We report upon the amphibians collected during seven expeditions carried out between the years 2000–2006 to thirteen localities in both Refugio de Vida Silvestre Río San Juan and Reserva Biológica Indio-Maíz, southeastern Nicaragua. We include morphometric data of around one-half of the adult specimens in the collection, and provide a brief general overview and discuss zoogeographic and conservation considerations of the amphibians known to occur in the Río San Juan area. Keywords. Amphibia, conservation, ecology, morphometry, zoogeography. Introduction potential of holding America’s first interoceanic channel and also because it was part of the sea route to travel The San Juan River is an approximately 200 km slow- from eastern to western United States. -
Conserving the Hip Hoppers: Amphibian Research at Greater Manchester Universities
REVIEW ARTICLE The Herpetological Bulletin 135, 2016: 1-3 Conserving the hip hoppers: Amphibian research at Greater Manchester Universities ROBERT JEHLE1*, RACHAEL ANTWIS1 & RICHARD PREZIOSI2 1School of Environment and Life Sciences, University of Salford, M5 4WT Salford, UK 2Faculty of Life Sciences, University of Manchester, M13 9PT Manchester, UK *Corresponding author Email: [email protected] Characterising Greater Manchester is not an easy task. As a hotbed of radical ideas, the rise of Greater Manchester during the industrial revolution was followed by a significant economic and population decline. As one of the fastest-growing regions in the United Kingdom of the 21st century, contemporary Greater Manchester is shaped by a conglomerate of different influences. The dynamic history of the area is also reflected in emerging herpetological research activities. Without a pronounced tradition in organismal herpetology, Greater Manchester has recently developed into a national hotspot for academic research on amphibian conservation. Perhaps most importantly, the emerged activities are largely shaped through efforts led by postgraduate students. The present overview summarises Figure 1. Participants of the 2015 Amphibian Conservation these developments. Research Symposium in Cambridge. The conference series A main home of amphibian research activities in Greater started in Manchester in 2012. Manchester is represented by the Manchester Amphibian Research Group (MARG, http://amphibianresearch.org), with a main goal to “advance both ex situ and in situ amphibian conservation through evidence-based research”.

Reserve. 3 Costa Rica is internationally recognized as one of the most biologically diverse countries on the planet in total species numbers for many taxonomic groups of flora and fauna, one of those being amphibians. Costa Rica has 190 species of amphibians known from within its tiny 51,032 square kilometers territory. With 3.72 amphibian species per 1,000 sq. km. of national territory, Costa Rica is one of the richest countries in the world regarding amphibian diversity density. Amphibians are under constant threat by contamination, deforestation, climatic change, and disease. The majority of Costa Rica’s amphibians are surrounded by mystery in regards to their basic biology and roles in the ecology. Through intense research in the natural environment and in captivity many important aspects of their biology and conservation can become better known. The Costa Rican Amphibian Research Center (C.R.A.R.C.) was established in 2002, and is a privately owned and operated conservational and biological research center dedicated to studying, understanding, and conserving one of the most ecologically important animal groups of Neotropical humid forest ecosystems, that of the amphibians. -

Myers, Ph.D., Chair, Department of Mathematics & Computer Science ABSTRACT Assisting Frog Identification in Costa Rica Using a Mobile App. LAPLANTE, JUSTIN (Department of Mathematics and Computer Science). Quickly identifying a single frog species from over a hundred other possible species can be a challenge for research while in the Costa Rican jungle. Though researchers can use field guides to assist, these still mean you may have look through all currently identified frog species to find the frog being viewed. This project was created to help researchers narrow the list of possible frog species quickly based on Geolocation. Using Xamarin.Forms, an app was developed that worked offline, used an ArcGIS API and was cross platform. However, to ensure performs and accuracy certain design choices were made for designing the ArcGIS map that was used within the app. The used geospatial data for the frog species and generalized it into a hexagonal pattern. -

However, this number is likely an underestimate due to the presence of many unexplored areas that are diffcult to access. Between 2012 and 2017, a monitoring survey of amphibians was conducted in the Central Caribbean of Costa Rica, on the northern edge of the Matama mountains in the Talamanca mountain range, to study the distribution patterns and natural history of species across this region, particularly those considered as endangered by the International Union for Conservation of Nature. The results show the highest amphibian species richness among Middle America lowland evergreen forests, with a notable anuran representation of 64 species. -

Some of these species had suffered from serious population declines, probably due to chytridiomycosis, but all are generally threatened by habitat loss. We detected 53% of the Endangered and 56% of the Critically Endangered amphibian species that have previously been reported from within the investigated area. We report on findings of species that have not been found in Panama for many years, and provide locality data of newly discovered populations. There is a need to create a new protected area in the Cerro Colorado area of the Serranía de Tabasará, where we found 15% of the Endangered and Critically Endangered am- phibian species known to Panama. -
