The recent industrial boom along the Australian coastline has increased concerns about the long term conservation of snubfin dolphins along the Queensland coast. National assessment of the conservation status and management of the Australian snubfin dolphin is currently hindered by the lack of adequate biological and ecological information throughout most of its range. In response to the issue ...
We provide a checklist of 45 species amphibians from Lai Chau Province, northwestern Vietnam. Thirteen are recorded for the first time Province; these include four Dicroglossidae, Megophryidae, three Ranidae, and two Rhacophoridae. also descriptions newly species. The amphibian fauna Province is high conservation concern, with endemic to Vietnam, 10 listed in IUCN Red List, Data Book
Green Plants in the Red: A Baseline Global Assessment for the IUCN Sampled Red List Index for Plants
Plants provide fundamental support systems for life on Earth and are the basis for all terrestrial ecosystems; a decline in plant diversity will be detrimental to all other groups of organisms including humans. Decline in plant diversity has been hard to quantify, due to the huge numbers of known and yet to be discovered species and the lack of an adequate baseline assessment of extinction risk...
The IUCN Red List has assessed the global distributions of the majority of the world's amphibians, birds and mammals. Yet these assessments lack explicit reference to widely available, remotely-sensed data that can sensibly inform a species' risk of extinction. Our first goal is to add additional quantitative data to the existing standardised process that IUCN employs. Secondly, we ask: do our ...
The IUCN (International Union for Conservation of Nature) Red List classifies species according to their risk of extinction, informing global to local conservation decisions. Unfortunately, important geospatial data do not explicitly or efficiently enter this process. Rapid growth in the availability of remotely sensed observations provides fine-scale data on elevation and increasingly sophisti...
We describe and illustrate a new species of Masdevallia from the Andean-Amazonian foothills Caquetá, Colombia. leonor-baeziana belongs to subsect. Saltatrices, within M. constricta group. It is most similar constricta, but it can be distinguished by shorter sepals sepaline tails that do not surpass tube length, shorter, sigmoid-ovate lip. proposed categorizing as Critically Endangered (CR) base...
We describe a new terrestrial frog from the puna grasslands adjacent to Mantaro dry valley in southern Peru. Phrynopus apumantarum sp. nov. is similar appearence P. bufoides but differentiable by lacking discoidal fold and enlarged warts on dorsum, prominent post ocular having canthal stripe. Lastly, we propose place species under Vulnerable (VU) category of IUCN Red List, due its small distrib...
