Scientists provide crucial data to prompt further conservation and safety measures at the notorious BR-262 highway

Having systematically monitored wild animals killed on the Brazilian federal highway BR-262, which passes through the Pantanal region, a research team from the Federal University of Mato Grosso do Sul, Brazil, published their data concerning birds and reptiles in the open access journal Check List.

Apart from information crucial for future conservation activities, the paper provides new and unexpected roadkill records, including the Black-and-white hawk-eagle.

Authored by Wagner Fischer and his colleagues Raquel Faria de Godoi and Antonio Conceição Paranhos Filho, the article is part of the first dataset of vertebrate mortality in the region. A separate paper of theirs is planned to present the data concerning mammals gathered during the same survey, which took place between 1996 and 2000.

Having mapped bird and reptile roadkill on the highway between the cities of Campo Grande and Corumbá in the Brazilian savannah, the team reports a total of 930 animals representing 29 reptile and 47 bird species. In addition, the data provide the first regional geographic record of the colubrid snake Hydrodynastes bicinctus.

The researchers conclude that the species richness observed in the road-killed animals clearly confirms earlier concerns about wildlife-vehicle collisions in the Pantanal region. Such accidents lead to long-term and chronic impact on both wildlife and road safety.

“Mitigation of wildlife-vehicle collisions on this road continues to claim urgency for biodiversity conservation and for human and animal safety and care,” say the authors.

“For managers, the main goal should be to determine target species of greatest concern, focusing on those vulnerable to local extinction or those which represent major risks of serious accidents.”

In the past, the team’s dataset had already been used as a guide to road fauna management. In particular, it was used by government road managers when planning animal overpassess and underpassess equipped with roadside fences as part of the long-term project Programa Estrada Viva: BR-262. So far, however, only some of the less efficient safety methods, such as road signs and lowered speed limits, have been applied at the most critical points.

Over the past several years, a few independent studies have been conducted to monitor roadkill in a similar manner. Two of them (2010 and 2017) looked into mammal-vehicle collisions, while the third recorded reptiles and birds as well. All of them serve to demonstrate that BR-262 continues to be a major cause for the regional wildlife mortality, which in turn increases the risks of serious accidents.

“BR-262 keeps its inglorious fame as a highway to hell for human and wild lives,” points out lead author Wagner Fischer.

The Alps are home to more than 3,000 lichens

Historically, the Alps have always played an emblematic role, being one of the largest continuous natural areas in Europe. With its numerous habitats, the mountain system is easily one of the richest biodiversity hotspots in Europe.

Lichens are curious organisms comprising a stable symbiosis between a fungus and one or more photosynthetic organisms, for example green algae and/or cyanobacteria. Once the symbiosis is established, the new composite organism starts to function as a whole new one, which can now convert sunlight into essential nutrients and resist ultraviolet light at the same time.

Being able to grow on a wide range of surfaces – from tree bark to soil and rock, lichens are extremely useful as biomonitors of air quality, forest health and climate change.

Nevertheless, while the Alps are one of the best studied parts of the world in terms of their biogeography, no overview of the Alpine lichens had been provided up until recently, when an international team of lichenologists, led by Prof. Pier Luigi Nimis, University of Trieste, Italy, concluded their 15-year study with a publication in the open access journal MycoKeys.

The scientists’ joint efforts produced the first ever checklist to provide a complete critical catalogue of all lichens hitherto reported from the Alps. It comprises a total of 3,138 entries, based on data collected from eight countries – Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia and Switzerland. In their research paper, the authors have also included notes on the lichens’ ecology and taxonomy.

They point out that such catalogue has been missing for far too long, hampering research all over the world. The scientists point out that this has been “particularly annoying”, since the data from the Alps could have been extremely useful for comparisons between mountainous lichen populations from around the globe. It turns out that many lichens originally described from the Alps have been later identified in other parts of the world.

“It was a long and painstaking work, which lasted almost 15 years, revealing a surprisingly high number of yet to be resolved taxonomic problems that will hopefully trigger further research in the coming years,” say the authors.

“We think that the best criterion to judge whether a checklist has accomplished its task for the scientific community is the speed of it becoming outdated,” they conclude paradoxically.

The new checklist is expected to serve as a valuable tool for retrieving and accessing the enormous amount of information on the lichens of the Alps

that has accumulated over centuries of research. It offers a basis for specimen revisions, critical re-appraisal of poorly-known species and further exploration of under-explored areas. Thus, it could become a catalyst for new, more intensive investigations and turn into a benchmark for comparisons between mountains systems worldwide.

Pensoft journals integrated with Catalogue of Life to help list the species of the world

While not every taxonomic study is conducted with a nature conservation idea in mind, most ecological initiatives need to be backed by exhaustive taxonomic research. There simply isn’t a way to assess a species’ distributional range, migratory patterns or ecological trends without knowing what this species actually is and where it is coming from.

In order to facilitate taxonomic and other studies, and lay the foundations for effective biodiversity conservation in a time where habitat loss and species extinction are already part of our everyday life, the global organisation Catalogue of Life (CoL) works together with major programmes, including GBIF, Encyclopedia of Life and the IUCN Red List, to collate the names of all species on the planet set in the context of a taxonomic hierarchy and their distribution.

Recently, the scholarly publisher and technological provider Pensoft has implemented a new integration with CoL, so that it joins in the effort to encourage authors publishing global taxonomic review in any of the publisher’s journals to upload their taxonomic contributions to the database.

Whenever authors submit a manuscript containing a world revision or checklist of a taxon to a Pensoft journal, they are offered the possibility to upload their datasets in CoL-compliant format, so that they can contribute to CoL, gain more visibility and credit for their work, and support future research and conservation initiatives.

Once the authors upload the dataset, Pensoft will automatically notify CoL about the new contribution, so that the organisation can further process the knowledge and contact the authors, if necessary.

In addition, CoL will also consider for indexing global taxonomic checklists, which have already been published by Pensoft.

It is noteworthy to mention that unlike an automated search engine, CoL does not simply gather the uploaded data and store them. All databases in CoL are thoroughly reviewed by experts in the relevant field and comply with a set of explicit instructions.

“Needless to say that the Species 2000 / Catalogue of Life community is very happy with this collaboration,” says Dr. Peter Schalk, Executive Secretary.

“It is essential that all kinds of data and information sharing initiatives in the realm of taxonomy and biodiversity science get connected, in order to provide integrated quality services to the users in and outside of our community. The players in this field carry responsibility to forge partnerships and collaborations that create added value for science and society and are mutually reinforcing for the participants. Our collaboration is a fine example how this can be achieved,” he adds.

“With our extensive experience in biodiversity research, at Pensoft we have already taken various steps to encourage and support data sharing practices,” says Prof. Lyubomir Penev, Pensoft’s founder and CEO. To better serve this purpose, last year, we even published a set of guidelines and strategies for scholarly publishing of biodiversity data as recommended by our own experience. Furthermore, at our Biodiversity Data Journal, we have not only made the publication of open data mandatory, but we were also the first to implement integrated narrative and data publication within a single paper.”

“It only makes sense to collaborate with organisations, such as Catalogue of Life, to make sure that all these global indexers are up-to-date and serve the world’s good in preserving our wonderful biodiversity,” he concludes.
