Moth genitalia is the key to snout grass borers from the Western Hemisphere

Two scientists have produced an illustrated key to define the subtle differences between the 41 species of snout moth grass borers that currently dwell in the Western Hemisphere. The researchers conclude that the adults moths are too tough to tell apart by external characters, and therefore, the only way to identify the species is by dissecting and comparing genitalia. The study is published in the open-access journal ZooKeys.

This identification key is compiled by Dr. M. Alma Solis and Dr. Mark Metz. Both scientists are Research Entomologists at the Agriculture Research Service’s Systematic Entomology Laboratory, USDA. Dr. Solis is Curator of the U.S. National Pyraloidea Collection located at the National Museum of Natural History, Smithsonian Institution Washington, D.C.

The caterpillars of this group of snout moth grass borers feed on crops such as sugarcane, corn, rice, sorghum, and on native grasses throughout the Western Hemisphere, which makes many of the species quite harmful pests.

“The caterpillars of snout moth borers are economically important worldwide as pests of planted crops used for food or biofuel, so their identity is important for their control,” says Dr. Solis. “A key with images provides a simple way to identify adult moths, especially those that cannot be distinguished easily. A key to their identification is one of the most important results of taxonomic research.”

This research required locating ‘type specimens’ or original individuals that were used to describe the species in museums, borrowing them and preparing them for studies while avoiding inflicting any damage, so that they can be used by future researchers. These special specimens are the “standard bearer” for the scientific name and solidify the morphological as well as the molecular identity of a species.

Furthermore, Dr. Solis explained that it is not only important to be able to recognize if a species is new to science, as she and her colleagues recently discovered with a species feeding on Eastern gamagrass in the United States. It is also crucial for tying a species’ scientific name to its biology or genetic composition.

The biology of many moth species is still a mystery, but a recent study, where Dr. Solis participated, identified and studied the biology of some of the species. It showed that there may have been two introductions of the sugarcane borer moth species to southeastern United States and it is likely that there is a species which is currently ‘hidden’ under the same name. She concluded that there is still much left to discover about these moth species from the Western Hemisphere.

Undergraduate student takes to Twitter to expose illegal release of alien fish in Japan

Posing a significant threat to the native biodiversity in Japan, specifically that of threatened aquatic insects, some alien fishes, such as the bluegill, have become the reason for strict prohibitions. All activities potentially capable of introducing the species into the wild are currently punishable by either a fine of up to 3 million yen for a person (100 million yen for corporations), or a prison sentence of up to 3 years.

Recently, ten years after the law has been adopted, illegal release of bluegill fish has been reported for the first time with the help of a post on Twitter from Akinori Teramura, undergraduate student at the Tokyo University of Marine Science and Technology and second author of the present study. The case is reported and discussed by him and two scientists, affiliated with Kanagawa Prefectural Museum of Natural History, Japan, in the open-access journal ZooKeys.

In June 2015, Akinori Teramura tweeted two photographs of the invasive bluegill fish, both adults and juveniles, along with two young goldfish, which do not belong to the local fauna, either. In his post he identified the species and shared his surprise at the irresponsibility of the people who had released the fish. When lead author Dr Yusuke Miyazaki saw the tweet, he signalled his colleagues with the idea to publish the information as a scientific report.

The student found them in an outdoor public pool in Yokohama city, Japan, while it was being cleaned before being opened ahead of the summer. Usually, these facilities are closed to the public during the colder seasons and it is then when native aquatic insect species, such as dragonflies and diving beetles, find spawning and nursery habitats in them. Curiously enough, though, the pool had been isolated from natural waters since its construction.

Therefore, the researchers conclude that the alien fishes have most likely been released from an aquarium from a local shop or an aquarist who no longer wanted them. However, the authors note that according to the law, keeping bluegill fish in a home aquarium is illegal as well.

“Our report demonstrates an example of web data mining in the discipline of Citizen Science,” say the authors. “Web data mining has been rapidly developing over recent years, and its potential continues to expand.”

“Community awareness of this issue needs to be improved, and widespread reporting of cases such as this one will help,” they conclude.

New bush tomato species is the link between botany and an Oscar-nominated Hollywood movie

A new Australian bush tomato species, discovered by a team of researchers led by biology professor Chris Martine of Bucknell University, has been named after main character Mark Watney from the book and film The Martian. The authors, among whom is the undergraduate student Emma Frawley, have published the new species in the open-access journal PhytoKeys.

Martine announced the new name, Solanum watneyi, in The Huffington Post last year when he described it as a tribute to the heroic portrayal of Watney as a NASA botanist and engineer who saves himself with plant science expertise after being stranded on Mars.

In fact, Matt Damon’s botanist character impressed both the audience and the critics so much that it resulted in several Academy Awards nominations to the whole production team. The actor himself received a Golden Globe among many other prestigious recognitions including the BAFTA for Best Actor and the Critics’ Choice Award for Best Actor.   

This is a botanist portrayal that turns an unusually bright spotlight on authentic scientific endeavor,” Martine explains the choice. “Scientist heroes are already unusual in Hollywood, but a space-deserted protagonist who studies plants as a profession is something extraordinary.

However, according to Martine, the decision to name the species after Watney also has some taxonomic relevance.

“The plant that Watney manages to grow on Mars is none other than Solanum tuberosum (the potato), a member of the same genus as our new species,” he says.

This connection was not missed by Andy Weir, author of the book-turned-movie and father of the Watney character, who expressed his approval of the name on his Facebook page.  

“What higher honor could a botanist like Watney ask for than to have a plant named after him?” writes Weir. “And to have it be a relative of the potato as well? Perfect!”

[PR] Solanum watneyi Martine Img2Martine collected specimens of the new species during a six-week expedition to the Northern Territory of Australia with his wife, Rachel, and their two children. Rachel drew the illustration of the species that appears in the PhytoKeys paper.

In order to make sure the new species is not in fact a previously known and closely related Solanum species, the family team collected hundreds of seeds of both species. Thus, the plants could be grown and compared side-by-side in a research greenhouse.

In the summer of 2015, Bucknell undergraduate student Emma Frawley, class 2017, studied the plants, ultimately gathering and analyzing enough morphometric data to confirm the distinctiveness of Solanum watneyi. This is how Frawley, a double major in environmental studies and Spanish, became a co-author of the present paper.

The new species occurs in and around the western part of Judbarra/Gregory National Park, where it was occasionally encountered by regional botanists who nicknamed the oddball plant “Bullita” after the cattle station that once operated in the area.

“The nickname started being applied in the 1970s,” said Martine, who studied historical collections of the plant at the Northern Territory Herbarium. “But no one had yet done statistical comparisons between that plant and its similar relative.”

Watney is not the only one being recognized by the botanical community following the release of The Martian. In recognition of his botanist star turn, the Botanical Society of America has extended an honorary membership to actor Matt Damon, who portrays the space botanist in the film.

 

Note:  Also listed as authors on the recent publication are Bucknell University Burpee Postdoctoral Fellow Jason Cantley and University of California-Berkeley Research Botanist Ingrid Jordon-Thaden.

World’s smallest of giant flowers discovered in the Philippines

Some of the world’s giant flowers, those of the parasitic plant genus Rafflesia, can reach up to a meter and a half in diameter. Therefore, what could be more impressive about them are ‘dwarves’ such as the record-breaking one that was recently discovered by scientists from the University of the Philippines Diliman and the University of the Philippines Los Baños. Its average diameter is only 9.73 cm and has been named  consueloae. The study is published in the open-access journal PhytoKeys.

Curiously enough, the discovery happened after a field assistant accidentally tripped over a pile of forest litter to expose a decayed flower. Later on, lead researcher Prof Perry S. Ong would describe the novel finding as “serendipitous”.

The new species is named Rafflesia consueloae in honor of Ms Consuelo ‘Connie’ Rufino Lopez, lifelong partner of Filipino industrialist Oscar M. Lopez. “With her demure, but strong personality traits, which Rafflesia consueloae also possesses, she provides the inspiration for Mr Lopez’s pursuit of biodiversity conservation in the Philippines,” Prof Ong says.

Rafflesia flowers are unique in that they are entirely parasitic on roots and stems of specific vines in the forests and have no distinct roots, stems, or leaves of their own,” explains co-author Prof Edwino S. Fernando. “Thus, they are entirely dependent on their host plants for water and nutrients.”

In Sumatra and Borneo another species of the same genus, Rafflesia arnoldi, holds the record of being the largest single flower in the world with a diameter of up to 1.5 meter. In the Philippines, Rafflesia schadenbergiana, found only in Mindanao, is still large with a flower diameter of 0.8 meter. Professor Fernando, added that Rafflesia consueloae is the 6th species from Luzon Island and the 13th for the entire Philippine archipelago.

The new species has been classified as Critically Endangered, based on IUCN criteria as it has less than 100 km2 extent of occurrence with its two small populations. The continued protection of the populations of this species is important as some local people still hunt wildlife within the area and forest fires are likely in the dry season, factors which might threaten the survival of R. consueloae.

The field and laboratory work of the field scientists are part of the Comprehensive Biodiversity Conservation Monitoring Program of Pantabangan-Carranglan Project, funded by the First Gen Hydro Power Corportation (FGHPC) and Wildlife Forensics and DNA Barcoding of Philippine Biodiversity of the University of the Philippines Diliman – Department of the Environment and Natural Resources – Biodiversity Management Bureau (DENR-BMB).

Four new orchid species discovered during Lengguru 2014 expedition, West Papua, Indonesia

One of the biggest scientific expeditions ever undertaken in Indonesia, Lengguru 2014, made it possible to study and collect dozens of unknown plant and animal species, including four new orchids. Curiously, the research team, led by Dr. Lina Juswara, Cibinong Science Centre, Indonesia, collected three of these novelties over the span of a single day at the top of a small and unexplored mountain at 1000-metre elevation. The findings, which confirm previous suggestions that many species still await discovery there, are described and published in the open-access journal Phytokeys.

Thanks to the 2014 Lengguru scientific expedition some of the mysteries of Lengguru, an almost impenetrable mountainous area in an isolated and difficult-to-reach part of the Indonesian half of the New Guinea island, have been revealed. About a hundred participants, including 25 European and 45 Indonesian scientists, took part in it with the shared goal to collect essential data on the biodiversity of West Papua.

Lengguru remains one of the last unexplored territories on the planet. Covering an area, comparable in size to Sardinia, it consists of limestone formations, known as ‘karst’, forming a mosaic of natural ecosystems. The Lengguru 2014 expedition attempted to investigate Lengguru’s biodiversity in order to generate scientific data for molecular, ecological, taxonomical and biogeographical studies.

During the 6-week expedition, 72 fertile/flowering orchid specimens have been collected from the field by the internal team of Indonesian, French and Belgian botanists. So far, four new species have been identified among them.

“After the expedition, we examined and compared the Lengguru orchids with reference material housed in scientific collections,” explains Dr. Lina Juswara. Together with Dr. Vincent Droissart from the Research Institute for Development, France, they were the experts in charge to gather data on the large and glamorous Orchid family during the expedition. The identifications, descriptions and drawings of the new species were realized in close collaboration with Dr. Andre Schuiteman, Royal Botanical Garden Kew, United Kingdom, an internationally recognized expert on the orchid flora of Asia.

New Guinea is known to harbor one of the richest orchid floras in the world, surpassed only by Colombia, Ecuador, and Peru. All four new orchid species discovered in Lengguru have been collected in high altitude forest, at over 1000 meters above sea level. These particular habitats, usually shrouded in clouds, are home to an exceptional plant diversity with a high degree of endemism, meaning the species cannot be found anywhere else in the world. The specific environmental conditions and the very small surface occupied by these ‘isolated islands’ of mountain forests make them particularly vulnerable to global climate change.

“Large parts of New Guinea have been overlooked in terms of collection initiatives and it is likely that many species still await discovery there”, says Dr. Lina Juswara. “More field studies are also required to find additional populations of the new species we found in Lengguru, in order to better characterize their habitat, ecology and conservation status. Of the four new orchid species collected during the expedition, three were collected on a single day, confirming that the flora of Lengguru is still far from completely described.”

The Castaway: New monitor lizard fills top-order predator role on remote Pacific island

Separated by several hundred kilometres from its next of kin, a new species of blue-tailed monitor lizard unique to the remote Mussau Island has been described. Unknown to science until recently and formally termed the “isolated”, it is the only large-sized land-living predator and scavenger native to the island.

Dubbed a “biogeographical oddity” by its discoverers, led by Valter Weijola, a graduate student from the University of Turku, Finland, the lizard species is also the first new monitor lizard to be described from the country of Papua New Guinea in over twenty years. The finding was published in the open-access journal ZooKeys.

Monitors play an important ecological role in many island ecosystems in the southwest Pacific. Predatory mammals have never colonized the region due to the isolation of these islands. Instead, these large, active and intelligent lizards fill the role of top-predators and scavengers. The Pacific monitor lineage to which the new species belongs have been so successful at oversea dispersal that a number of different species now occupy almost every island from the Moluccas in Indonesia to the eastern Solomon Islands and even Micronesia.

The new endemic species was observed and studied during fieldwork by Weijola and local assistants in the relatively dry coastal vegetation of Mussau, but it is likely that it also persist in the remnants of intact forest in the interior of the island.

in habitat

The formally described female lizard, or holotype, measures 1 m with the tail being one and and a half times the length of the dominantly black-coloured body covered with yellow and orange markings. The tail of the adults shows varying degrees of turquoise to bluish pigmentation. Another distinctive feature for the species is the pale yellow tongue, which is a trait shared only by three other species of Pacific monitors. The new species is known to eat crabs, other reptiles and their eggs, and small birds.

“Usually monitors like these will eat just about anything they can catch and kill, as well as carcass and turtle eggs when available,” explains Weijola. “While young, Pacific monitor lizards are highly secretive and subsist mainly on insects and other small animals.”

The new species, which can grow to well over a meter in length, was named Varanus semotus, a Latin reference to the remoteness and isolation of the relatively small and partly volcanic island where the lizard was found. Close examination revealed the reptile to be distinct from its relatives from New Guinea and New Britain. Genetic studies, conducted by co-authors Stephen Donnellan, South-Australian Museum, and Christer Lindqvist, Åbo Akademi University, showed that the species has been isolated for a long time, estimatedly 1-2 million years, or even longer.

Varanus2

“Isolation is the keyword here,” says Weijola. “It is what has driven speciation and made the South-Pacific region one of the World’s biodiversity hotspots.” For anything to arrive on Mussau (from New Guinea or New Britain) it would need to cross 250-350 kilometers of open sea, and this doesn’t happen frequently. So, once the ancestor arrived, perhaps in the form of a gravid female, the population must have been completely isolated.””These islands are full of unique creatures often restricted in distribution to just one island or island group,” explains the researcher. “Yet, we know relatively little about them. Even large species of reptiles and mammals are regularly being discovered, not to mention amphibians and invertebrates. This is what makes it such a biologically valuable and fascinating region.”

All Pensoft journals now integrated with Peerage of Science

Collaboration is a major driver of scientific advancement. Pensoft recognises this and has now integrated all of its journals with Peerage of Science — a platform with a mission to foster new levels of collaboration between scientists.

This integration between two innovative platforms, striving to modernize the publishing industry, provides authors with the possibility not only to receive fast-track high-quality peer review of their manuscripts, but also to have a choice between a pool of journals, when it comes to publication.

“Pensoft is a special partner for us, because they were the first publisher to start an official collaboration with Peerage of Science years ago, when we had just launched. Also, Pensoft is in many ways a pioneering publisher seeking to make the world a better place for scientists, with initiatives like the ARPHA writing tool and the RIO Journal,” explains Janne-Tuomas Seppänen, Co-Founder and Managing Director at Peerage of Science.

“I am particularly happy that Pensoft is continuing and expanding its support for our solutions for peer review, and brings more journals to the author’s destination menu in Peerage of Science. We warmly welcome the 10 new titles and their editors, and look forward to a long and productive partnership.” he adds.

The idea behind Peerage of Science was inspired by the real-world struggles a young scientist is bound to face in the traditional peer-review system. The average peer review process takes more than 160 days and could easily conclude with the paper being rejected.

The initiative applies an out-of-the-box approach to the problem, providing a collaborative platform, where peer review takes place before the actual submission to a journal. Thus the process is significantly shortened, while at the same time it secures high quality manuscripts at the end.

Similarly, Pensoft journals provide open access, new generation publishing to scientists with an emphasis of online dissemination, data re-use and semantic linking of contents. With its latest projects — RIO Journal and the ARPHA writing tool — the publisher has introduced a new generation of pre-submission and post publication peer review possibilities.

Additional benefit for the reviewers is that their reviews will be registered at Publons automatically by Pensoft, if the manuscript is published in a Pensoft journal. Reviewers will be asked for approval of the review registration before it appears in their Publons profiles.

“This collaboration works well both for us and for Peerage of Science, but most of all, it empowers the authors to set the deadlines for peer review and choose between publication offers. From the very inception of Pensoft we have striven to provide a fast, reliable and innovative service to our authors, and this new move is yet another building block in this vision.” comments Prof. Lyubomir Penev, Founder and Managing Director at Pensoft.

 

African Invertebrates migrates to Pensoft’s journal publishing platform

One of the oldest zoological journals in Africa, African Invertebrates, is now moving to Pensoft to benefit from the next generation publishing offered by the company. The journal focuses on the taxonomy, systematics, biogeography, biology, ecology, conservation and palaeontology of all Afrotropical invertebrates.

Established as early as 1906 by the KwaZulu-Natal Museum as Annals of the Natal Museum, the journal was renamed to African Invertebrates in 2003 to mark the centenary of the founding of the museum and to declare its ambition to establish itself as a recognizable title in taxonomy. Throughout the years the journal has been building reputation and strengthening its position as a primary outlet for publishing original research on African insects and other invertebrates.

The migration to Pensoft marks yet another step forward in the journal’s development placingAfrican Invertebrates on the map of technologically advanced journals with a mission to provide semantically enriched, interlinked and re-usable content.

“The transfer of African Invertebrates to Pensoft is an exciting development for the KwaZulu-Natal Museum. We are immensely proud of the journal and have striven to maintain and enhance its high quality. However, we realise that the journal must also keep pace with new trends and developments in the fast-moving world of scientific publication.” comments Prof. Dai Herbert, Editor-in-Chief of African Invertebrates.

“We are delighted that Pensoft has agreed to include African Invertebrates in its journal portfolio. This kind of cutting-edge publishing platform is precisely what the journal needs to ensure its future relevance and growth. We are excited to see African Invertebrates enter this new phase in its development.” he adds.

The international peer-reviewed e-journal will now be hosted on the ARPHA publishing platform, benefitting from a number of inbuilt innovations, including:

  • Fast-track professional publication services;
  • Open access, semantically enriched content;
  • Online publication in HTML, semantically enhanced with biodiversity-specific markup provided by the publisher, high resolution, full-color, print-quality PDF, as well as XML;
  • Archiving in various data repositories;
  • A number of additional services including linguistic editing, tailored dissemination campaigns and more.

“We are pleased to welcome African Invertebrates on board. Our experience in advanced open access publishing as well as our domain specific expertise promise good future for our collaboration with the KwaZulu-Natal Museum to innovate and develop the journal.” explains Prof. Lyubomir Penev, Founder and Managing Director at Pensoft.

Conservation hopes up for the endangered banana frog restricted to Southwest Ethiopia

As the natural forest cover in Ethiopia is already less than 3% of what it once has been, the banana frog species, dwelling exclusively in the remnants of the country’s southwestern forests in only two populations, is exposed to a great risk of extinction.

Through their survey, a research team, led by Matthias De Beenhouwer, Biodiversity Inventory for Nature Conservation (BINCO), Belgium, have now extended the species’ range, thus making the first steps to saving the charming frogs. The study is published in the open-access journal ZooKeys.

Although Ethiopia is known for its high number of both animal and plant species that do not live anywhere else in the world, there is a concerning lack of conservation activities to preserve the local biodiversity. Moreover, while as much as 41% of the amphibians ever recorded in the country are exclusive for its fauna, there have been only few researches. Without such, pointing the hotspots in greatest need of protection and restoration, as well as taking adequate measures subsequently, is impossible.

7114_banana frog blog img3

Concerned about the endangered status of the banana frog, and supported with a Rufford grant, Matthias and his team spent ten evenings, or 111 hours, in August 2014, seeking and collecting as many frogs as possible from seven different locations. When they determined the species status of the found individuals, it turned out that they have managed to discover several new populations of banana frogs from unexpected localities.

As a result of their survey, the geographical range of the Ethiopian banana frog has been expanded by roughly 40 km towards the North and 70 km to the East. Its altitudinal distribution already reaches a maximum of 2030 metres above sea level, compared to the previously known maximum of 1800 m.

Banana frogs being identified from outside forest habitats is also a good news for the species’ preservation since it shows that not only are the frogs more tolerable against forest degradation than expected, but that also there could be even more populations.

“Although Southwest Ethiopia is known to harbour the last large tracts of natural forest, forest cover has declined dramatically to less than 3% nationwide,” point out the researchers. “Therefore, accurate information on species conservation and distribution is an essential first step to facilitate the delivery of conservation updates, recognize biodiversity hotspots and encourage habitat protection and restoration.”

New species with heart-shaped fruits inspires a love for biodiversity in Hawai’i

Just in time for Valentine’s Day, botanists from Hawai’i have discovered a new species of plant with small heart-shaped fruits. The new species is a member of the coffee family (Rubiaceae) and part of the genus Coprosma, which occurs across many remote islands of the Pacific Ocean. They named the new Hawaiian species after the symbol of love – calling it Coprosma cordicarpa – meaning the Coprosma with heart-shaped fruit. Their research is published in the open-access journal PhytoKeys.

 

The botanists, who discovered C. cordicarpa, describe their finding as the result of a loving adventure with Hawaiian biodiversity. It began when Hawai’i’s State Botanist Dr. Maggie J. Sporck-Koehler noticed the little heart-shaped fruits in the Kanaio Natural Area Reserve on the Island of Maui, while attending a work meeting with the Department of Land and Natural Resources (DLNR), Division of Forestry and Wildlife (DOFAW).

 

One of the primary mandates of DOFAW is to conserve Hawai’i’s native ecosystems and the species that reside in them. As State Botanist, Sporck-Koehler is most often working on issues relating to rare or State and Federally listed threatened and endangered (T&E) plant species. Gaining a better understanding of native Hawaiian plant conservation status and helping to facilitate conservation efforts is one of the main objectives of the work she does for the State. Therefore, when something extraordinary gets under her nose, such as an unusual Coprosmapopulation, she takes a note and a sample.

 

Sporck-Koehler attempted to identify the species using a key so that she could know what she was looking at. She got to Coprosma foliosa, but was not satisfied. So, she turned to Dr. Jason T. Cantley, who at the time was finishing his PhD research on the genus Coprosma at the University of Hawai’i at Manoa Department of Botany. “I was very taken with it,” Sporck-Koehler told Cantley. “It seemed different than any other [Coprosma] foliosas I’ve seen.”

Image2_CantleyCoprosmacordicarpa

Then, Cantley concluded that the heart-shaped fruits and other characteristics looked different enough that it was worth it to visit specimens at the Bernice Pauahi Bishop Museum in Honolulu, and then to examine the plants themselves. “We needed to get all our ducks in a row, making sure we knew what we were looking for before we flew to Maui,” Cantley says. “Part of that planning was to think about the long-term conservation of Coprosma cordicarpafrom the start. That’s one reason it was necessary to bring Dr. Chau into this project.”

 

Dr. Marian M. Chau is the Seed Conservation Laboratory Manager at Lyon Arboretum’s Hawaiian Rare Plant Program in Honolulu. The Seed Conservation Lab‘s mission is to aid in the prevention of extinction of Hawaiian plant species by maintaining a long-term seed bank collection, to propagate plants for use in approved restoration projects, and to conduct research on seed storage and germination for the Hawaiian flora. The Seed Conservation Lab currently stores over 11 million seeds from about 40% of all Hawaiian native species, with the ultimate goal to represent the entire flora with research and/or long-term germplasm collections. This includes under-described biodiversity, like the heart-shaped fruits of C. cordicarpa.

 

From early on, it was clear that C. cordicarpa was not all that common, as it can only be found on one island. In fact, the botanists determined the new species fell within the International Union for Conservation of Nature (IUCN) Red Vulnerable Category (VU) for extinction risk. The VU is the lowest of the three threatened Red List categories, but indicates that C. cordicarpastill faces threats of extinction in the wild. Chau suggested that they collect seeds for long-term germplasm storage at the Seed Conservation Lab.

 

Two field adventures on Maui and many herbarium specimen measurements later, the authors were confident they were looking at a new species. All in all, 609 seeds from 32 plants were collected, which are going to help preserve the biodiversity of this species for many years to come.

 

The authors had a passion for Hawaiian plant biodiversity and conservation well before this project, but it was the discovery of the heart-shaped fruits that brought these three botanists together. With their naming of this new species, they hope to also inspire others with a love for biodiversity that will continue long into the future.
