Jiuzhaigou National Nature Reserve, a World Heritage Site, lies in the transition zone from the eastern edge of the Qinghai-Tibet Plateau to the Sichuan Basin in Sichuan Province, China, and occupies an area of 651 km2. The reserve is covered with well-preserved original forests, and numerous alpine lakes. Beautiful and picturesque, it is home to some rare animals, such as the Giant Panda (Ailuropoda melanoleuca) and Golden Snub-nosed Monkey (Rhinopithecus roxellana).

The herpetological diversity, in contrast to the mammals, is relatively low in the area due to the harsh alpine environment. To find out more about it, and to investigate the post-earthquake ecological system in the region, a group of researchers conducted a series of investigations in Jiuzhaigou National Nature Reserve. During their herpetological surveys, they collected some specimens of Gloydius, a genus of venomous pit vipers endemic to Asia, from Zharu Valley.
After running morphological and phylogenetic analyses, the scientists found out that these specimens in fact belonged to a yet-to-be-described species.

“The new species is morphologically similar, and phylogenetically closely related to G. swild, another recently described species from Heishui, Aba, Sichuan, but differs from it by having larger eyes (related to the head) and a continuous regular brown stripe on each dorsolateral side of the body,” explained the corresponding author, Dr Jingsong Shi.
“Thus, we named it after its unique color pattern: Gloydius lateralis.”

The newly described snake feeds on small mammals, such as mice, and “is active on sunny days by the roadside in a hot, dry valley”, the researchers write in their study, which was published in the open-access scientific journal ZooKeys.
“The discovery of G. lateralis provides new insights into the diversity and the distribution patterns of Asian pit vipers”, they write, suggesting that the formation of the Qinghai-Tibet Plateau might be one of the key factors to the geographical isolation of the alpine pit vipers in southwest China.

Jiuzhaigou National Nature Reserve, where G. lateralis was found, receives millions of tourists every year. “The only known habitat of the new species is Zharu Valley, and it is now under touristic development,” the researchers point out. “Thus, warning signs are still needed to remind visitors to watch out for the venomous pit viper, since this and another pit viper species, Protobothrops jerdonii, are often found in grass or bushes on both sides of roads.”
Snakes’ thermoregulation needs make them more prone to vehicle collisions, which is why the research team highlights the necessity to remind drivers to slow down in order to avoid road killings.

In the world of biodiversity science, 2022 started with some great discoveries and a lot of hope. Here at Pensoft, we get to see a new species (or more!) make an appearance into the scientific world almost every day. The diversity is impressive, but what is even more amazing is how much more remains undiscovered.
With the first half of the year already behind us, here are the stellar new species that took the world by storm as soon as we published them.
The magical fairy wrasse
This rainbow-coloured fish is called Cirrhilabrus finifenmaa, or Rose-Veiled Fairy Wrasse, and it was found in the Maldives’ reefs. It can live 160 to 500 feet beneath the ocean’s surface in unexplored coral ecosystems dubbed “the twilight zone”.
“Nobody knows these waters better than the Maldivian people,” says senior author and Academy Curator of Ichthyology Luiz Rocha. “Our research is stronger when it’s done in collaboration with local researchers and divers.”
Media attention for our new species isn't slowing down, so I'll keep promoting it! Did you know that in addition to looking incredible in life, the new C. finifenmaa is also fluorescent!? Here's an unreleased photo taken by T. Gerlach and J. Theobald. https://t.co/EVwOtCvRc3pic.twitter.com/aqCNFvbzja
Apart from its striking appearance, Cirrhilabrus finifenmaa also gained popularity as the first new-to-science species to be described by a Maldivian scientist.
“It has always been foreign scientists who have described species found in the Maldives, even those that are endemic, without much involvement from local scientists, says study co-author and Maldives Marine Research Institute biologist Ahmed Najeeb. “This time it is different.”
It is also one of the first species to have its name derived from the local Dhivehi language, ‘finifenmaa’ meaning ‘rose’, a nod to both its pink hues and the island nation’s national flower.
This beautiful fish is already being exploited through the aquarium hobbyist trade, a fact described as “unsettling” by the people who discovered it.
How often is it that a millipede makes top news headlines? Well, Nannaria swiftaesure did.
Scientists Derek Hennen, Jackson Means, and Paul Marek, at Virginia Tech, U.S., described the new species in April, naming it after singer-songwriter Taylor Swift. “Her music helped me get through the highs and lows of graduate school, so naming a new millipede species after her is my way of saying thanks,” Derek Hennen says, admitting he has been her fan for years.
N. swiftae joins 16 other new species of twisted-claw millipedes described from the Appalachian Mountains of the United States. To find them, researchers traveled to 17 US states, checking under leaf litter, rocks, and logs. They then sequenced the DNA of the species they found and described them scientifically. They looked at over 1800 specimens collected on their field study or taken from university and museum collections!
These little-known invertebrates are somewhat tricky to catch, because they tend to remain buried in the soil, sometimes staying completely beneath the surface.
Most twisted-claw millipedes live on the forest floor, where they feed on decaying leaves and other plant matter. They also have a valuable role as decomposers: breaking down leaf litter, they release their nutrients into the ecosystem.
Swedish climate activist Greta Thunberg has been namesakes with a frog for half a year now. In 2018, Rainforest Trust celebrated its 30th anniversary by hosting an auction offering naming rights for some new-to-science species, including Pristimantis gretathunbergae, a black-eyed rainfrog from in eastern Panama.
The undisclosed auction winner wanted to name the frog in honor of Thunberg and her work in highlighting the urgency in preventing climate change. She has impressed global leaders and her work is drawing others to action for the climate.
The international team that discovered the new rainfrog was led by Abel Batista, Ph.D. (Panama) and Konrad Mebert, Ph.D. (Switzerland). They found the frog on Mount Chucanti, a sky island surrounded by lowland tropical rainforest in eastern Panama. Reaching its habitat in the cloud forest required access via horseback through muddy trails, hiking up steep slopes, by-passing two helicopters that crashed decades ago, and camping above 1000 m elevation.
Unfortunately, the frog’s remaining habitat is severely fragmented and highly threatened by rapid deforestation for plantations and cattle pasture. Rising temperatures are another threat as they could destroy its small mountain habitat. The Mount Chucanti region already has lost more than 30% of its forest cover over the past 10 years, and the scientists insist that conservation of the remaining habitat is critical to ensure the survival of the frog.
Instantly gaining popularity as Chocolate Frog, Synapturanus danta is a curious little frog that was recently discovered in the Peruvian Amazon. Local people had long known about this tiny, burrowing frog with a long snout; one local name for it is rana danta, “tapir frog”, for its resemblance to the large-nosed Amazonian mammal.
“These frogs are really hard to find, and that leads to them being understudied,” says Michelle Thompson, a researcher in the Keller Science Action Center at Chicago’s Field Museum and one of the authors of the study describing the frog. “It’s an example of the Amazon’s hidden diversity, and it’s important to document it to understand how important the ecosystem functions.”
While the frogs are hard to see, they’re not hard to hear. “We just kept hearing this beep-beep-beep coming from underground, and we suspected it could be a new species of burrowing frog,” says Thompson. “But how do we get to it?”
Local guides who were familiar with the frogs led the researchers to peatland areas– wetlands carpeted with nutrient-rich turf made of decaying plant matter. “After 15 to 20 minutes of digging and looking for them, I heard Michelle screaming, and to me that could only mean that she and David had found the first adult,” says Germán Chávez, a researcher at Peru’s Instituto Peruano de Herpetología and the study’s first author.
The researchers used the physical specimens of the frogs, along with the recordings of their calls and an analysis of the frogs’ DNA, to confirm that they were a new species. They named them Synapturanus danta – Synapturanus is the name of the genus they belong to, and danta is the local word for “tapir.”
This magnificent non-venomous snake, previously unknown to science, was discovered in Paraguay. It belongs to the genus Phalotris, a group of snakes from central South America noted for their striking coloration with red, black, and yellow patterns.
Jean-Paul Brouard, one of the involved researchers, came across an individual of the new species by chance while digging a hole at Rancho Laguna Blanca in 2014. Together with his colleagues Paul Smith and Pier Cacciali, he described the discovery, naming the new snake Phalotris shawnella.
The species name recognizes two children – Shawn Ariel Smith Fernández and Ella Bethany Atkinson – who were born in the same year as the Fundación Para La Tierra (2008). They inspired the founders of the NGO to work for the conservation of Paraguayan wildlife, in the hope that their children can inherit a better world.
🐍 This lovely #snake is the latest addition to the #herpetofauna of Paraguay. The team that discovered it, however, worries that this beautiful and highly endemic #NewSpecies is not well protected.
This new Phalotris snake is particularly attractive and can be distinguished from other related species in its genus by its red head in combination with a yellow collar, a black lateral band and orange ventral scales with irregular black spots.
Only known from three individuals, this species is endemic to the Cerrado forests of the department of San Pedro in east Paraguay. Its extreme rarity led the authors to consider it as “Endangered”, according to the conservation categories of the International Union for Conservation of Nature (IUCN), which means it is in imminent danger of extinction in the absence of measures for its protection.
Invasive species volunteers are driven by unique motivations, like the desire to support species management, conserve native species, and protect livelihoods.
Public involvement is an important component of many invasive species programmes. Volunteers perform early detection of invasive species, track their spread, and also play active roles in their capture, control and removal. Their involvement helps raise awareness of invasive species and encourages support for their management. Finding, recruiting and retaining a corps of committed volunteers, however, can be a challenge. Understanding the reasons why people participate in invasive species projects is critical for successful volunteer recruitment and the long-term sustainability of volunteer-driven projects.
A multidisciplinary team of invasion biologists and social scientists from the AlienCSI network funded by the COST programme, led by Ana Anđelković, used a meta-synthesis approach to analyze volunteer motivations in the monitoring and control of invasive alien species. They published their study in the open-access journal NeoBiota.

“Citizen participation in invasion monitoring and control is clearly a booming business. Yet almost nothing is known about why volunteers engage in such programmes. We wanted to close that knowledge gap and make recommendations to project managers to keep their volunteer armies engaged, which is often as hard as tackling the invasive species itself. For this, we mined the literature for motivation statements”, explains Anđelković.
Searching through literature, the team found 264 motivations, which they then classified into 15 broader motivations. Generally, motivations fit three broad themes: reflecting environmental concerns, social motivations, and personal reasons.

“Some motivations, such as being in the great outdoors, making friends, taking care of a particular nature reserve, learning something new and having fun, are in line with other forms of environmental volunteering. They apply to many projects where citizen-scientists help to record sightings of invasive species around the world. But volunteers in invasive species projects seem to be unique in their desire to take part in the control and eradication of these species, to protect native biodiversity in the places they value,” says Anđelković.
“For instance, on Scottish seabird islands, people helped remove invasive tree mallow to protect the breeding puffins. In South Africa, volunteers want to rid the unique Fynbos of invasive trees. In some regions of the world people also take part in harvest management for food provision, as is the case with lionfish in the Caribbean or common carp in Australia.”

However, the relative lack of published studies and invasive species projects that have actually measured volunteer motivations was striking. “Motivations change over time and the reasons why people remain active in invasive species management are often not the same as their initial self-reported motivation,” they comment. “Also, the social implications for people taking part in eradication campaigns that involve the killing of invasive animals, or the cutting of trees to prevent the spread of insect pests, are not sufficiently understood.”
In conclusion, the authors call upon researchers and project managers to gather data on participant motivations in collaboration with social scientists, especially when volunteers are also involved in control. This way, projects can be inclusive of diverse groups of people, tailoring tasks and roles to everyone’s interests and capabilities.

Ask any scientist — for every “Eureka!” moment, there’s a lot of less-than-glamorous work behind the scenes. Making discoveries about everything from a new species of dinosaur to insights about climate change entails some slogging through seemingly endless data and measurements that can be mind-numbing in large doses.
Community science shares the burden with volunteers who help out, for even just a few minutes, on collecting data and putting it into a format that scientists can use. But the question remains how useful these data actually are for scientists.
A new study, authored by a combination of high school students, undergrads and grad students, and professional scientists showed that when museum-goers did a community science activity in an exhibit, the data they produced were largely accurate, supporting the argument that community science is a viable way to tackle big research projects.
“It was surprising how all age groups from young children, families, youth, and adults were able to generate high-quality taxonomic data sets, making observations and preparing measurements, and at the same time empowering community scientists through authentic contributions to science,”
“This study demonstrates the wonderful scientific outcomes that occur when an entire community comes together,”
says Melanie Pivarski, an associate professor of mathematics at Roosevelt University (USA) and the study’s lead author.
“We were able to combine a small piece of the Field Museum’s vast collections, their scientific knowledge and exhibit creation expertise, the observational skills of biology interns at Northeastern Illinois University (USA), led by our collaborator Tom Campbell, and our Roosevelt University student’s data science expertise. The creation of this set of high-quality data was a true community effort!”
The study focuses on an activity in an exhibition at the Field Museum, in which visitors could partake in a community science project. In the community science activity, museumgoers used a large digital touchscreen to measure the microscopic leaves photographs of plants called liverworts.
These tiny plants, the size of an eyelash, are sensitive to climate change, and they can act like a canary in a coal mine to let scientists know about how climate change is affecting a region. It’s helpful for scientists to know what kinds of liverworts are present in an area, but since the plants are so tiny, it’s hard to tell them apart. The sizes of their leaves (or rather, lobes — these are some of the most ancient land plants on Earth, and they evolved before true leaves had formed) can hint at their species. But it would take ages for any one scientist to measure all the leaves of the specimens in the Field’s collection. Enter the community scientists.
“Drawing a fine line to measure the lobe of a liverwort for a few hours can be mentally strenuous, so it’s great to have community scientists take a few minutes out of their day using fresh eyes to help measure a plant leaf. A few community scientists who’ve helped with classifying acknowledged how exciting it is knowing they are playing a helping hand in scientific discovery,”
says Heaven Wade, a research assistant at the Field Museum who began working on the MicroPlants project as an undergraduate intern.
Community scientists using the digital platform measured thousands of microscopic liverwort leaves over the course of two years.
“At the beginning, we needed to find a way to sort the high quality measurements out from the rest. We didn’t know if there would be kids drawing pictures on the touchscreen instead of measuring leaves or if they’d be able to follow the tutorial as well as the adults did. We also needed to be able to automate a method to determine the accuracy of these higher quality measurements,”
says Pivarski.
To answer these questions, Pivarski worked with her students at Roosevelt University to analyze the data. They compared measurements taken by the community scientists with measurements done by experts on a couple “test” lobes; based on that proof of concept, they went on to analyze the thousands of other leaf measurements. The results were surprising.
“We were amazed at how wonderfully children did at this task; it was counter to our initial expectations. The majority of measurements were high quality. This allowed my students to create an automated process that produced an accurate set of MicroPlant measurements from the larger dataset,”
says Pivarski.
The researchers say that the study supports the argument that community science is valuable not just as a teaching tool to get people interested in science, but as a valid means of data collection.
“Biological collections are uniquely poised to inform the stewardship of life on Earth in a time of cataclysmic biodiversity loss, yet efforts to fully leverage collections are impeded by a lack of trained taxonomists. Crowd-sourced data collection projects like these have the potential to greatly accelerate biodiversity discovery and documentation from digital images of scientific specimens,”
says von Konrat.

“…the most realistic and tangible way out of the looming biodiversity crisis is to put a price tag on species and thereby a cost to actions that compromise them.”
So far, science has described more than 2 million species, and millions more await discovery. While species have value in themselves, many also deliver important ecosystem services to humanity, such as insects that pollinate our crops.
Meanwhile, as we lack a standardized system to quantify the value of different species, it is too easy to jump to the conclusion that they are practically worthless. As a result, humanity has been quick to justify actions that diminish populations and even imperil biodiversity at large.
In a study, published in the scholarly open-science journal Research Ideas and Outcomes, a team of Estonian and Swedish scientists propose to formalize the value of all species through a conceptual species ‘stock market’ (SSM). Much like the regular stock market, the SSM is to act as a unified basis for instantaneous valuation of all items in its holdings.
However, other aspects of the SSM would be starkly different from the regular stock market. Ownership, transactions, and trading will take new forms. Indeed, species have no owners, and ‘trade’ would not be about transfer of ownership rights among shareholders. Instead, the concept of ‘selling’ would comprise processes that erase species from some specific area – such as war, deforestation, or pollution.
“The SSM would be able to put a price tag on such transactions, and the price could be thought of as an invoice that the seller needs to settle in some way that benefits global biodiversity,”
explains the study’s lead author Prof. Urmas Kõljalg (University of Tartu, Estonia).
Conversely, taking some action that benefits biodiversity – as estimated through individuals of species – would be akin to buying on the species stock market. Buying, too, has a price tag on it, but this price should probably be thought of in goodwill terms. Here, ‘money’ represents an investment towards increased biodiversity.
“By rooting such actions in a unified valuation system it is hoped that goodwill actions will become increasingly difficult to dodge and dismiss,”
adds Kõljalg.
Interestingly, the SSM revolves around the notion of digital species. These are representations of described and undescribed species concluded to exist based on DNA sequences and elaborated by including all we know about their habitat, ecology, distribution, interactions with other species, and functional traits.
For the SSM to function as described, those DNA sequences and metadata need to be sourced from global scientific and societal resources, including natural history collections, sequence databases, and life science data portals. Digital species might be managed further by incorporating data records of non-sequenced individuals, notably observations, older material in collections, and data from publications.
The study proposes that the SSM is orchestrated by the international associations of taxonomists and economists.
“Non-trivial complications are foreseen when implementing the SSM in practice, but we argue that the most realistic and tangible way out of the looming biodiversity crisis is to put a price tag on species and thereby a cost to actions that compromise them,”
says Kõljalg.
“No human being will make direct monetary profit out of the SSM, and yet it’s all Earth’s inhabitants – including humans – that could benefit from its pointers.”

The BiCIKL project invites submissions of Expression of Interest (EoI) to the First BiCIKL Open Call for projects. The purpose of this call is to solicit, select and implement four to six biodiversity data-related scientific projects that will make use of the added value services developed by the leading Research Infrastructures that make the BiCIKL project.
By opening this call, BiCIKL aims to better understand how it could support scientific questions that arise from across the biodiversity world in the future, while addressing specific scientific or technical biodiversity data challenges presented by the applicants.
We need and want to assess real-world problems and make the best possible use of our data and technical capabilities. This will greatly assist in defining the long-term development goals of the participating Research Infrastructures and improve the way they can technically and operationally work together to deliver greater scientific value.
explain the project partners.
The BiCIKL project – a Horizon 2020-funded project involving 14 European institutions, representing major global players in biodiversity research and natural history, and coordinated by Pensoft – establishes a European starting community of key research infrastructures, researchers, citizen scientists and other biodiversity and life sciences stakeholders based on open science practices through access to data, tools and services.
Deep in the forests of Odisha and Andhra Pradesh in India lives a colourful gecko species that only now revealed its true identity. Meet Eublepharis pictus, also known as the Painted Leopard Gecko.
In 2017, researchers Zeeshan A. Mirza of theNational Centre for Biological Sciences in Bangalore and C. Gnaneswar of theMadras Crocodile Bank Trust in Chennai found a gecko in a water tank near a temple in Vishakhapatnam, Andhra Pradesh, during a field survey. Back then, they identified it as belonging to the East Indian Leopard Gecko species (Eublepharis hardwickii).
“The species appears to be common in the hill forests, but its distinctness was only confirmed by other researchers,” Zeeshan Mirza explains.
In a phylogenetic study, where they looked for the evolutionary history and relationships within and between the leopard gecko species in the genus Eublepharis, the researchers found that what had until then been considered a southern population of East Indian Leopard Geckomight be distinct enough to represent a new species.
Once they had molecular data they could work with, the team made morphological comparisons between the species, looking at specimens across natural history museums.

“These lizards have conserved morphologies and most species are quite similar in general appearance,” Zeeshan Mirza elaborates. “With a few characters based on the number of specimens examined, we described the species and named it the Painted Leopard Gecko – in Latin, Eublepharis pictus, for its colouration.” Theypublished their discovery in the open-access scientific journalEvolutionary Systematics.
With this new addition, the gecko genus Eublepharis now contains 7 species. Two of them – E. pictus and E. satpuraensis – were described by Zeeshan Mirza.
The Painted Leopard Gecko measures 11.7 cm in length, which is somewhat large for a leopard gecko. The Brahmani River, which runs through the Eastern Ghats, separates it geographically from the East Indian Leopard Gecko, with which it shares a lot of similar traits.
The new species lives in dry evergreen forests mixed with scrub and meadows. It is strictly nocturnal, actively foraging along trails in the forest after dusk. While looking for food, it has been observed licking surfaces as it moves, which suggests it might use its tongue as a sensory organ.
Even though the Painted Leopard Gecko seems to be widespread across the state of Odisha and northern Andhra Pradesh, the researchers worry about its conservation. “The species is collected for the pet trade and even now may be smuggled illegally,” they write in their paper, which is why they refrain from giving out the exact locations where it may be found.

The authors believe the species would stand more of a chance against humans if more people knew it was actually harmless. To protect it, they suggest listing it as Near Threatened based on IUCN conservation prioritisation criteria, until more is known about the size of its populations.
Further research may also encourage better protection of biodiversity in the area. “The Eastern Ghats are severely under-surveyed, and dedicated efforts will help recognize it as a biodiversity hotspot,” the authors conclude.

Against the odds, a study by Brazilian researchers describes a new to science species of evidently cave-bound – or troglobitic – clam from northern Brazil.
Exclusively subterranean bivalves – the group of molluscs comprising clams, oysters, mussels, scallops – are considered a rarity. Prior to the present study, there had only been three such species confirmed in the world: all belonging to a small-sized mussel genus known from southeastern Europe. Furthermore, bivalves are not your typical ‘underworld’ dweller, since they are almost immobile and do not tolerate environments low in oxygen.

Named Eupera troglobia, the mollusk demonstrates features characteristic for organisms not meant to see the daylight, including lack of pigmentation, reduced size, delicate shell and fewer, yet larger eggs.
Curiously, it was back in 2006 when a report presenting a faunal survey of a cave in northern Brazil featured photographs of what was to be described as Eupera troglobia. However, the evidence was quickly dismissed: the clam must have been carried into the cave by water.

In 2010, Dr Rodrigo Lopes Ferreira accessed the report and noticed the depigmentation of the clams. Wondering whether it was indeed possible that he was looking at a troglobite, he searched amongst the collected specimens from that study, but could not find any of the discoloured bivalve.
Ten years later, his team visited the cave to specifically search for depigmented shells. Although the cave was partially flooded, the researchers were able to spot the specimens they needed attached to the walls of the cave.
In conclusion, the scientists highlight that their discovery is the latest reminder about how important the conservation of the fragile subterranean habitats is, given the treasure troves in their holdings.
Meanwhile, recently amended laws in Brazil put caves at considerably higher risk.

From 17th to 21st October 2022, the Biodiversity Information Standards (TDWG) conference – to be held in Sofia – will run under the theme “Stronger Together: Standards for linking biodiversity data”.
Between 17th and 21st October 2022, the Biodiversity Information Standards (TDWG) conference – to be held in Sofia, Bulgaria – will run under the theme “Stronger Together: Standards for linking biodiversity data”.
In addition to opening and closing plenaries, the conference will feature 14 symposia and a mix of other formats that include lightning talks, a workshop, and panel discussion, and contributed oral presentations and virtual posters.
For a seventh year in a row, all abstracts submitted to the annual conference are made publicly available in the dedicated TDWG journal: Biodiversity Information Science and Standards (BISS Journal).
Thus, the abstracts – published ahead of the event itself – are not only permanently and freely available in a ‘mini-paper’ format, but will also provide conference participants with a sneak peek into what’s coming at the much anticipated conference.
The new special issue of BioRisk compiles materials presented at the International Seminar of Ecology – 2021. The multidisciplinary nature of modern ecology was demonstrated by the main topics of the Seminar: biodiversity and conservation biology, biotic and abiotic impact on the living nature, ecological risk and bioremediation, ecosystem research and services, landscape ecology, and ecological agriculture.
Research teams from various universities, institutes, organizations, and departments, both from Bulgaria and abroad, took part in the Seminar. Foreign participants included: Environmental Toxicology Research Unit (Egypt), Pesticide Chemistry Department, National Research Centre (Giza, Egypt); National Institute for Agrarian and Veterinary Research (Oeiras, Portugal), Centre for Ecology, Evolution and Environmental Changes (Lisbon, Portugal); Bach Institute of Biochemistry, Research Center of Biotechnology of the Russian Academy of Sciences (Moscow, Russia).
Some of the reports presented joint research of Bulgarian scientists and scientists from Germany, the Czech Republic, Lithuania, Romania, Slovenia, Spain, and the USA. After assessment by independent reviewers, the articles published in the journal cover the topics presented and discussed at the Seminar.
A set of reports were focused on the anthropogenic and environmental impacts on the biota. Soil properties were shown as a factor that can modulate the effect of heavy metals, present in chronically contaminated soils. Different approaches to overcome environmental pollution were presented and discussed: zeolites as detoxifying tools, microalgae for the treatment of contaminated water bodies, and a newly developed bio-fertilizer, based on activated sludge combined with a bacterial strain with detoxifying and plant growth-promoting properties. The clear need for the enlargement of existing monitoring program by including more bioindicators and markers was pointed out.
It was shown that, by using various markers for the evaluation of environmentally induced stress response at different levels (microbiological, molecular, biochemical), it is possible to gain insights of the organisms’ protection and the mechanisms involved in resistance formation. The contribution of increased DNA repair capacity and AOS to the development of environmental tolerance or adaptation was also shown.
Important results for understanding the processes of photoprotection in either cyanobacteria or algae, and higher plants were obtained by in vitro reconstitution of complexes of stress HliA protein with pigments. The crucial role of the cellular physiological state, as a critical factor in determining the resistance to environmental stress with Q cells was demonstrated.
Several papers were focused on the action of bioactive substances of plants origin. The bioactivity was shown to depend strongly on chemical composition. Origanum vulgarehirtum essential oil was promoted as a promising candidate for the purposes of “green” technologies. Analyzing secondary metabolites of plants, it was shown that their productivity in vitro is a dynamic process closely related to the plant growth and development, and is in close relation with the interactions of the plant with the environment.
The influence of the agricultural system type on essential oil production and antioxidant activity of industrially-cultivated Rosa damascena in the Rose valley (Bulgaria) was reported, comparing organic vs conventional farming. The rose extracts from organic farming were shown to accumulate more phenolic compounds, corresponding to the higher antioxidant potential of organic roses.
A comparative study, based on official data from the statistics office of the EU and the Member countries, concerning viral infection levels in intensive and organic poultry farming, demonstrated that free-range production had a higher incidence of viral diseases with a high zoonotical potential.
Pollinators of Lavandula angustifolia, as an important factor for optimal production of lavender essential oil, were analyzed. It was concluded that, although lavender growers tend to place beehives in the fields for optimal essential oil production, it was crucial to preserve wild pollinators, as well.
Lavandula angustifolia inflorescence excluded from pollinators.
New data reported that essential oils and alkaloid-rich plant extracts had the strongest acetylcholinesterase inhibitory activity and could be proposed for further testing for insect control.
It was reported that the vegetation diversity of Bulgaria had still not been fully investigated. Grasslands, broad-leaved forests, and wetlands are the best investigated habitats, while data concerning ruderal, shrubland, fringe, and chasmophytic vegetation in Bulgaria are scarce.
Other important topics were reported and discussed in this session: the possibility of pest control using pteromalids as natural enemies of pests in various crops; the main reasons responsible for the population decrease of bumblebees – habitat destruction, loss of floral resources, emerging diseases, and increased use of pesticides (particularly neonicotinoids); the strong impact of temperature and wind on the distribution of zooplankton complexes in Mandra Reservoir, in Southeastern Bulgaria; an alternative approach for the ex-situ conservation of Stachys thracica based on in vitro shoot culture and its subsequent adaptation under ex vitro conditions.

New information was presented concerning pre-monitoring geochemical research of river sediments in the area of Ada Tepe gold mining site (Eastern Rhodopes). The obtained results illustrate that the explored landscapes have been influenced by natural geochemical anomalies, as well as, impacted by human activity. The forests habitat diversity of Breznik Municipality was revealed, following the EUNIS Classification and initial data from the Ministry of Environment and Water and the Forestry Management Plans. It was shown that, in addition to the dominant species Quercus dalechampii, Quercus frainetto, Fagus sylvatica, Carpinus betulus, some artificial plantations with Pinus nigra and Pinus sylvestris were also present, as well as non-native species, such as Robinia pseudoacacia and Quercus rubra.
Models for Predicting Solution Properties and Solid-Liquid Equilibrium in Cesium Binary and Mixed Systems were created. The results are of great importance for the development of strategies and programs for nuclear waste geochemical storage. In conclusion, many results in different areas of ecology were presented in the Seminar, followed by interesting discussions. A lot of questions were answered, however many others remained open. A good platform for further discussion will be the next International Seminar of Ecology – 2022, entitled Actual Problems of Ecology.
