New open access journal Rethinking Ecology publishes novel ideas under Pensoft’s imprint

Needless to say, it is through sharing new ideas and hypotheses that critical issues such as climate change and biodiversity loss can be addressed. However, few scientists are currently in a position to do so, because publishing bold ideas in peer-reviewed journals is very difficult, especially for those who are not world-renowned scientists in their field. At the same time, scientists sharing novel ideas that have not been published yet, carry the risk of being ‘scooped’. This is probably a scientist’s worst nightmare: seeing someone else publish the idea they have been working on. In this context, many innovative ideas are kept secret and it can take years before they are made available to the scientific community.

This is the niche that the novel open access peer-reviewed journal Rethinking Ecology aims to fill by providing a platform for forward thinking and publication of novel ideas in all aspects of ecology, evolution and environmental science.

Adding to its innovative nature, Rethinking Ecology joins the modern technologically advanced Pensoft journals published on next-generation platform ARPHA (abbreviation standing for Authoring, Reviewing, Publishing, Hosting and Archiving). Not only is the platform to provide fast-track and convenient publishing for the authors, reviewers and editors in Rethinking Ecology, as it takes care of a manuscript through all stages from authoring and reviewing to dissemination and archiving, but it is user-friendly to the readers as well, who enjoy publications in three formats (PDF, XML, HTML) and full of semantic enhancements.

The innovative journal aims to encourage all scientists, regardless of their seniority, publication track record, gender, or country of origin, to publish perspective papers, so that they are put in the open for peers to discuss and build on, while credit is given where credit is due. Publishing these ideas early also draws attention from the scientific community, potential collaborators and potential funders. To further avoid potential bias, Rethinking Ecology implements double-blind peer review, with the journal supporting the notion that it is the content of a manuscript that matters. Moreover, reviewers will not be asked for a formal recommendation. Instead, they will comment and evaluate the work against a set of specific questions. Thus, each paper ends up with a score on Novelty, Feasibility, Scholarship and Literacy, so that only perspective papers with an emphasis on novel hypotheses and bold ideas are accepted for publication.

Another innovative feature applied in the new journal is an Author Contribution Index (ACI), meaning that each publication will include a pie chart pointing to the contribution of each of the authors, estimated in percentage. This is the editors’ answer to the so-called ‘guest authorship’ (i.e. inclusion of authors who did not significantly contribute to the work).

It is no coincidence that Rethinking Ecology has a spiral-shaped unfurling fern leaf as a logo. Called Koru in the language of the indigenous Polynesian people of New Zealand – Māori, it symbolises novelty, new life and new beginning, as well as perpetual movement.

“Each publication in Rethinking Ecology can be seen as the beginning of life for a new idea and its metaphorical unfurling as it reaches out to the scientific community,” explain the journal editors in their very first Editorial at Rethinking Ecology.

“We see Rethinking Ecology as an incubator for novel ideas, and a catalyst for new thinking,” says the journal’s Editor-in-Chief Dr Stephane Boyer, Unitec Institute of Technology, New Zealand.

“In a world where scientific publications are increasingly open source and immediately available, it makes no sense to keep our most innovative ideas hidden from the world for years while we secretly test them,” he elaborates. “Bold ideas and new hypotheses need to be shared, they may or may not turn into world-changing paradigm shifts, but they all have the potential to contribute to new thinking.”

“I am pleased to welcome a groundbreaking journal such as Rethinking Ecology to the Pensoft family, which has already built a nice and extensive portfolio of innovations in scholarly publishing,” says Pensoft’s founder and CEO Prof. Lyubomir Penev. “Seeing genuine ideas and hypotheses yet to be tested, and possibly, yet to revolutionise the ecological science is certainly a thing worthy of eager anticipation.”

Could green façades cool down cities in the future

Predictions for temperature rise and the particular sensitivity of urban ecosystems to heat stress pose a pressure to find the best solution for mitigation and adaptation to climate change. Could green façades be a sustainable and easy to implement strategy to keep our cities cool? A new study in the open access journal One Ecosystem uses the method of Bayesian networks to assess applicability of this nature-based solution, within the context of Berlin’s urban environment.

Urban heat is a recognised challenge for mid-latitude cities possibly aggravated by global climate change. Among the strategies to adapt the urban fabric, façade greening has been identified as an important measure to adjust the building stock and new buildings to adverse climatic impacts. Yet, little is known on factors that influence implementation probabilities for this adaptation measure.

Façade greening could be rather suitable way to establish vegetation in cities despite the development pressure. Not used for other purposes, unlike most of the horizontal green and open spaces in cities, façade greening needs very little space on the ground eliminating pressure and user competition.

In the past years, most German cities have developed climate change adaptation strategies which particularly focus on nature-based measures for urban planning to tackle the impacts of urban heat. In 15 of the 24 German adaptation strategies façade greening is mentioned as a measure to improve microclimatic conditions. But what is the likelihood of implementing and what is the attitude towards this measure?

Analysing attitudes and possibilities in the context of Berlin, a group of scientists found out that experts in Berlin estimate the likelihood of an implementation of façade greening under current conditions at 2% only. A different scenario including financial incentives from a backyard greening program, however, has shown to raise the chances to 14 %. Nonetheless, the factor of “willingness” of involved actors and the right combination of supportive and legislative factors appeared as a crucial pre-condition for the implementation of this measure.

“Our analysis allowed for ranking the influence of each of the factors on the outcome the research and we were surprised to see that in this case the “attitude” of determinant actors is of outmost importance, while financial prerequisites, legal and technical conditions also have an influence on the decision to install green façades but remain lower on the list.” comments the lead author of the study Nora Sprondel, Technische Universität Berlin, Germany.

A new species of quillwort named for the US state of Mississippi

Stunningly underwhelming, species of the genus Isoetes, commonly known as quillworts, bear amazing similarity to grass plants with which they are often confused. The US state of Mississippi has now given its name to a new species of the enigmatic quillwort group. The study was published in the open access journal PhytoKeys.

The new species, Isoetes mississippiensis, is an unusually large representative of the genus, first discovered in 1996 by Mr. Steve Leonard. For years it was known by the informal name “Big Dog”, a reference to its size.

Further microscopic and cytological study by Rebecca Bray, Lytton Musselman, and Peter Schafran (Old Dominion University, Norfolk, Virginia, USA); and W. Carl Taylor (National Museum of Natural History, Smithsonian Institution, Washington, D.C.) revealed that this is in fact a new species, rather than a strange form of a wide-ranging Midwestern species of Isoetes.

Interestingly, despite considerable field work, only two populations of I. mississippiensis are known from a tributary stream of the Pearl River, suggesting the extreme rarity of this Mississippi endemic, which already puts the new species at risk of extinction from human development.

What is the importance of this discovery and why does this often overlooked group matter? Despite their understated looks, quillworts can have an important role in biodiversity and conservation science, helping us interpret the environment — water quality, phytogeography, and evolution.

The unexpected and unexplored diversity of quillworts in the American South, for example, could be due to the machinations of glaciers, according to scientists. The last glacial epoch pushed northern quillworts south where they could cross with previously isolated species.

“Understanding the diversity of quillworts and their genetic makeup allows making hypotheses as to the movement of these plants and, by extension, to other plants in the same flora,” comments one of the co-authors Dr. Musselman. “We do not know how old this species is but we do know that it has been able to survive in its present habitat despite extensive perturbation of hydrology and natural vegetation.”

“When one southern Senator was told about an endangered quillwort in his state, he made a public statement questioning why anyone would be interested in this “grass”,” shares Musselman. “Despite their ecological importance, quillworts are largely ignored due to their understated appearance. No one knows how many quillworts have been extirpated without being described, and what those could tell us about the past and future of their environment.”

Foreign beetle species recorded for the first time in Canada thanks to citizen science

With social networks abound, it is no wonder that there is an online space where almost anyone can upload a photo and report a sighting of an insect. Identified or not, such public records can turn out to be especially useful — as in the case of an Old World beetle species — which appears to have recently entered Canada, and was recently discovered with the help of the BugGuide online portal and its large citizen scientist community.

Having identified the non-native rove beetle species Ocypus nitens in Ontario, Canada, based on a single specimen, author Dr Adam Brunke, affiliated with the Canadian National Collection of Insects, Arachnids and Nematodes, Ottawa, sought additional data to confirm his discovery.

Eventually, he found them in the citizen-generated North American digital insect collection BugGuide, created and curated by an online community of naturalists, insect enthusiasts and entomologists. After he verified as many as 26 digital photographs to be records of the same species, he concluded that the rove beetle has expanded its distribution to two new locations — Ontario, its first in Canada, and the state of Vermont, USA. His study is published in the open access Biodiversity Data Journal.

The species O. nitens is a fairly large rove beetle measuring between 12 and 20 mm in length and visibly distinguished by the characteristic form of the head and relatively short forewings. Furthermore, the insect is quite easy to spot because it prefers living around humans, often being spotted in woodlots and backyards.

As a result of the hundreds of years of Transatlantic trade, many species have been transported accidentally among various produce to subsequently adapt and establish on the other side of the ocean. While the rove beetle species O. nitens was first reported from the Americas in 1944, it was not until the turn of the new millennium that it escaped the small area in New England, USA, which had so far been its only habitat on the continent. Then, its distributional range began to rapidly expand. It is unlikely that the presence of this rove beetle, especially in Ontario, has long remained undetected, because of thorough and multiple sampling initiatives undertaken by professionals and students in the past.

The effect of the newly recorded species on the native rove beetles is still unknown. On the other hand, there are observations that several related beetles have experienced a drop in their populations in comparison to the records from the beginning of the century.

“Citizen-generated distributional data continues to be a valuable ally in the detection of adventive insects and the study of their distributional dynamics,” concludes the author.

Ottawa confirmed as the biodiversity hotspot for a subfamily of wasps in North America

What usually comes to mind when speaking about biodiversity hotspots are tropical regions, pristine areas and magnificent forests. Meanwhile, it is quite rare that a city in a temperate zone is considered significant in terms of biodiversity, much less mentioned as a hotspot. Yet, the city of Ottawa together with its surroundings, despite having population surpassing 1 million people, is now confirmed to be the locality in North America with the most recorded species of braconid wasps in the subfamily Microgastrinae, a group of parasitic insects that attack caterpillars and play an important role in the natural biocontrol of agriculture and forestry pests.

A study published in ZooKeys reports 158 species within 21 different genera of Microgastrinae for Ottawa. “To put this into perspective,” says Dr. Jose Fernandez-Triana, affiliated with the Canadian National Collection of Insects and lead author of the paper, “if Ottawa (a relatively small area of less than 7,800 km2) would be considered as a country itself, its species total would rank 17th among all countries in the world.”

There are close to 200 species of microgastrine wasps known from Canada and around 350 – from North America. Thus, the fauna in Ottawa equals to three quarters of the total recorded for the entire country, and almost half of all species in the Nearctic region. In fact, the diversity in the Canadian capital represents by far the highest number of species ever recorded for a locality in North America, a consequence of the city being a transition from an eastern deciduous forest biome to a boreal biome, with small areas of unusual habitats like dunes, alvars, floodplains and bogs.

Based on the analysis of almost 2,000 specimens, collected between 1894 and 2010, and housed in the Canadian National Collection of Insects, the paper also reports two new species for North America and two additional species records for Canada and Ontario, as well as dozens of new additions to the regional fauna. Seasonal distribution showed several peaks of activity, in spring, summer, and early fall.

The study highlights the incredible diversity of parasitoid wasps and how much remains to be discovered, even in temperate areas and/or city environments. “It is possible that southern localities in North America are eventually found to be more diverse than Ottawa,” notes Dr. Fernandez-Triana. “But for that to happen one would need to find an area that has a variety of habitats and has also been thoroughly sampled over the years, with thousands of specimens available for study.”

“In the meantime,” jokes the scientist, “the citizens of the Canadian capital will have the bragging rights in North America, at least for microgastrine wasp diversity.”

Disentangling the myth of the singing bushmaster viper with the help of tree frogs

Reaching over 3.5 m in length, the bushmaster (belonging in the Lachesis genus) is the largest viper in the western hemisphere. Legend spread among both colonists and natives from the Amazon region and Central America has it that it sings. Finding these numerous unrelated reports quite puzzling, since it is well known that snakes cannot sing, scientists took to finally disentangle the myth.

When the researchers recently conducted fieldwork in Amazonian Ecuador and Peru, they revealed it was not the snake singing. The ‘song’ was indeed the call of large tree frogs that live in hollow trunks in the forest.

While local guides in both countries attributed the songs to the bushmaster, the amphibians were almost completely unknown. To their surprise, instead of finding a snake, the field teams found two species of frogs of the genus Tepuihyla. The results are published in the open access journal ZooKeys in a collaborative effort by scientists from Catholic University of Ecuador, the Peruvian Institute of Research of the Amazon, Ecuadorian Museum of Natural Sciences, and Colorado State University, USA.

One of the tree frogs is a new species, Tepuihyla shushupe. The word shushupe is used by native people to refer to the bushmaster. The calls are highly unusual for frogs because they are a loud chuckle resembling the song of a bird. It is still unknown why locals associate the calls of the two species with the bushmaster.

Two new lizards with ‘heroic past’ discovered in the Chilean Andes

Two new species of lizards have been discovered in the Andean highlands of Southern Chile. Collected from areas of heroic past, both small reptiles were named after courageous tribal chiefs who have once fought against colonial Spaniards in the Arauco war. The study, conducted by a team of Chilean scientists, is published in the open access journal ZooKeys.

Jaime Troncoso-Palacios from Universidad de Chile and his team found both new species near a lake in a pre-Andean zone among deciduous vegetation. Following the examination of the collected specimens and further analysis of their mitochondrial DNA, performed by Dr. Alvaro A. Elorza from Universidad Andres Bello, Chile, the scientists concluded that they belong to species unknown to science.

One of the species, called Liolaemus janequeoae, or, Janequeo`s Lizard, is distinct for being smaller than its relatives, measuring a maximum of roughly 7 centimeters at length, as well as having no pattern on its back. Both features are quite striking for the group of lizards it belongs to. The only contrasting coloration for the species are several white scales appearing on the upper side in males. Otherwise, the species are predominantly light brown with pearly whitish down side of the body.

In the local Lonko tribe’s history, Janequeo was a prominent chief, who lost her partner during the Arauco war, after he was caught and tortured to death by the colonial Spaniards. She is said to have had a leading role in the Battle of Fort Puchunqui. Coincidentally, the new species was discovered where the war once took place, in the Araucanía Region.

The second new species, called Liolaemus leftrarui, or Leftraru`s Lizard, was collected from the same locality, hence it also received a heroic name honoured in the Arauco war. It is called after the most prominent Mapuche tribal chief. According to the stories, he was taken by the Kingdom of Chile’s Governor at the age of 11 to become his servant. There, however, he learned the military strategy of the Spanish, managed to escape and joined his people in the war. Later, not only did he kill his former master, but also won the most remarkable victories over the Spaniards.

The Leftraru`s Lizard is a large species of about 8 centimeters in length, characterised with absent precloacal pores, a common feature for its lizard group, save few. On the upper side of its body there are also unusual light blue dots. Overall, its colour is brown splashed with dark brown spots. Apart from the blue scattered scales on the back, there is also a bit of green on its head, limbs and tail. At the rear it becomes yellowish.

In conclusion, the authors note that the lizard fauna of Chile has been mistakenly assumed to be quite scarce up until recently. Yet, their latest discovery, along with several other new species, described in recent years, could be a clear sign that, “some populations under study could be described as new species in the future”.

The Caucasus as an ‘island’ in the ‘sea’ of steppes: New insights in mosquito evolution

From a geographical point of view, the Caucasus is far from an island or even a peninsula, being a relatively big mountainous region appearing as a fence at the border of Europe and Asia, situated between the Black and the Caspian seas. However, a study into the chromosome structure of mosquito larvae of the species Glyptotendipes salinus, living by a saltwater lake in the foothills of the Caucasus, suggests that the region could be imagined as an “island” in the “sea” of steppes.

Scientists Dr Mukhamed Karmokov, Tembotov Institute of Ecology of Mountain territories, Russian Academy of Science, and Dr Azamat Akkizov, Institute of Biomedical Problems, RAS, and Center of Medico-Ecological Researches, have their paper, where they describe the Caucasian population of the species, published in the open access journal Comparative Cytogenetics.

Earlier, it has been known that in the Tambukan Lake, located at the foothills of the Caucasus Mountains, lives at least one of the representatives of the genus Glyptotendipes, more precisely, the species G. salinus. Actually, the process of studying the fauna of the genus in the Caucasus region has just began and many questions have remained unclear.

During their research, the authors collected a sufficient amount of larvae of G. salinus that made it possible to study the chromosome structure, rearrangements and peculiarities of the Caucasian population of the species. In addition, the authors tried to understand how the population relates to the previously studied ones, living in the Altai region of Russia and Kazakhstan.

Researchers found interesting, some of them even striking, peculiarities in the chromosome structure and morphology of the larvae from Caucasus. Namely, they found four new chromosome rearrangements, likely unique for the Caucasus. Also, some of the chromosome characters were most similar to the mosquitoes from Altai, while others — to the population in Kazakhstan. The most curious difference of the Caucasian larvae in comparison to data from earlier studies was that they were twice as short.

In conclusion, the authors note that from the obtained data it could be deduced that that the Caucasian population had undergone a significant divergence, or even that it represents a subspecies.

Also, it turns out that the Caucasus itself is a relatively isolated and complex region in terms of microevolution. “The Caucasus, in some sense, can be imagined as a relatively isolated territory, a special place, where evolution has made some unexpected twists,” they say.

Plants cheat too: A new species of fungus-parasitizing orchid

Plants usually produce their own nutrients by using sun energy, but not all of them. A new ‘cheater’ species of orchid from Japan, lives off nutrients obtained via a special kind of symbiosis with fungi. The study was published in the open access journal PhytoKeys.

The new orchid species, named Lecanorchis tabugawaensis, is by far not on its own in its strange feeding habits. The so called mycoheterotrophic plants are found among all plant species groups.

Mycoheterotrophy is a term derived from Greek to describe the bizarre symbiotic relationship between some plants and fungi, where the plant gets nutrients parasitizing upon fungi, rather than using photosynthesis.

Considered a kind of a cheating relationship, these plants are sometimes informally referred to as “mycorrhizal cheaters”.

Having long attracted the curiosity of botanists and mycologists, a common feature of most mycoheterotrophic plants is their extreme scarcity and small size. In addition, most species are hiding in the dark understory of forests, only discoverable during the flowering and fruiting period when aboveground organs appear through the leaf litter.

Despite it seems like these ‘cheating’ plants have it all easy for themselves, in reality they are highly dependent on the activities of both the fungi and the trees that sustain them. Such a strong dependency makes this fascinating plant group particularly sensitive to environmental destruction.

“Due to the sensitivity of mycoheterotrophic plants it has long been suggested that their species richness provides a useful indicator of the overall floral diversity of forest habitats. A detailed record of the distribution of these vulnerable plants therefore provides crucial data for the conservation of primary forests,” explains leading author Dr Kenji Suetsugu, Kobe University.

Just discovered, the new orchid species has been already assessed with an IUCN status – Critically Endangered. With a distribution restricted to only two locations along the Tabu and Onna Rivers, Yakushima Island, this fungus-eating cheater might need some conservation attention.

Global change, ecosystem services and human well being: An assessment for Europe

Highly dependent on the different aspects of global change, variations in ecosystem services supply can also have direct impacts on human well being. A new article published in the open access journal One Ecosystem assesses the relationships between climate and land use change and ecosystem services supply in Europe, to pave the way on research connecting them to adaptation and human well being in a changing world.

Ecosystem services arise when ecological structures or functions contribute toward meeting a human demand. With global change impacting biodiversity and ecosystems properties, ecosystem services supply are also likely to be affected, consequently impacting various aspects of human well being.

In this context, assessing the possible bio-physical impacts of the ongoing and future changes in climate and land use becomes highly relevant for designing mitigation and adaptation policies.

While undergoing a comprehensive climate and land use impact assessment continues to be a demanding research challenge due to the large knowledge gaps, in their new paper, the team of scientists from the European Commission’s Joint Research Centre, Ispra, Italy and the Institute for Environmental Studies at the VU University Amsterdam, the Netherlands, present a first of its kind spatially explicit preliminary assessment of the changes in ecosystem services supply as a function of these global change drivers.

Carried out for the mainland of the 28 Member States of the European Union, the focus of this analysis is on regulating ecosystem services, due to their direct dependency on the proper functioning of ecosystems. Focusing on three regulating services: air quality regulation, soil erosion control, and water flow regulation, the new research presents an assessment of changes related to global change and their projected impacts, positive or negative, on human well being in the different European regions.

“Considering both land use projections and climate change scenarios in our research, in principle, enabled us to capture the main pressures acting on ecosystems and their services, thus enhancing the suitability of this approach to generate policy-relevant information,” explains the authors. “Yet, this study is only preliminary and a stepping stone for further research, needed not only to expand the analysis to other ES, but also to incorporate processes and scaling properties of the systems considered as they become available, and to account for spatial dependencies.”
