Introduction
It is just plain good luck to have been born in one of the biodiversity' richest countries in the World and, on top of that, to have moved to work and live in a biodiversity hotspot with the highest numbers of total and endemic species. #Venezuela #NorthernAndes #Flora&Fauna. This tropical paradise, being full of evolutionary surprises, revealed to me a diverse world that ended up directing my main interests. #Herpetology #Amphibians #ConservationBiology. Being surrounded by high mountains also canalized an unusual interest to reach high peaks and to protect the life in the surrounding ecosystems. My C.V. is to be found in: http://www.saber.ula.ve/handle/123456789/9857. This is me and my production, but by any means my totality...

La rana “sifrina” invade Mérida
Conference Paper
Full-text available
In the course of providing support to endangered animals, it comes out that the most benefited are usually those that are either large, colorful, or have some unusual attributes. However, the vast majority of species in peril commonly lack them and hence go unattended. The amphibians are not an exception. Most of the considerations go to colorful s...

Boana xerophylla is a common treefrog widely distributed in northern Brazil, Colombia, French Guiana, Guyana, Panama, Suriname, Trinidad and Tobago, and Venezuela. A recent study found molecular, acoustic, and morphometric differences between the populations located on opposite sides of the Orinoco River. Here, we carry out an updated molecular phy...

La ciudad de Mérida, en los Andes de Venezuela, está rodeada de altas montañas con predominancia de ambientes de páramo y de bosque nublado. En estos últimos se encuentra una variedad de anfibios, muchos de los cuales están amenazados de extin-ción. La ranita de La Culata (Aromobates duranti) es uno de ellos. Común a comienzos de los años 80 del si...

A progress report note on how the COVID-19 pandemic affected activities and posing problems to conservation efforts at the REVA Conservation Center. Since REVA conservation programs imply in situ, ex situ, and community outreach projects, the collateral adverse effects of the virus werealso multifold. REVA fieldwork, lab, and teaching activities we...

Pristimantis telefericus se propone como una especie en peligro de extinción.Fue originalmente descrita de elevaciones cercanas a los 3.500 m. snm en el Parque Nacional Sierra Nevada. La especie había permanecido esquiva a pesar de varias búsque-das durante este siglo. Los registros estuvieron ausentes durante veinte años después de la primera reco...

Pristimantis telefericus, a high Andean Venezuelan frog known to exist at no more than four locations, is facing a high risk of extinction after experiencing an estimated reduction in population size of ≥50% over the last twenty years. The reduction of its causes are suspected to be linked to climate change and/or the presence of the Bd, but with t...

Lambert et al . question our retrospective and holistic epidemiological assessment of the role of chytridiomycosis in amphibian declines. Their alternative assessment is narrow and provides an incomplete evaluation of evidence. Adopting this approach limits understanding of infectious disease impacts and hampers conservation efforts. We reaffirm th...

El patrimonio hidráulico y la cultura del agua en Iberoamérica dan como resultado un paisaje cultural creado por el hombre, siglo tras siglo, donde se superponen los legados de varios pueblos. El agua es aquí un elemento de diferenciación paisajística y se constituye, por tanto, como marca distintiva en el territorio y la memoria local. El acercami...

This research focuses on the study of an ancient geo-archaeological irrigation ditch located at El Platanal, a small mountain village located in the Sierra Nevada of Merida, in the Venezuelan Andes. To the best of our knowledge, it is the first time that this hydric configuration is reported. We first present an overview of the ancestral hydric sys...

Atelopus is a species-rich group of Neotropical bufonids. Present knowledge on bioacoustics in this genus is relatively poor, as vocalisations have been described in only about one fifth of the ca. 100 species known. All studied members of the genus produce vocalisations although, with a few exceptions, most species lack a middle ear. Nonetheless,...

La Culata’s Frog (Aromobates duranti) was described in 1985 and a few additional specimens were deposited in museums until the end of that same decade. Subsequently it seems to have disappeared, judging by the absence of visual records or collections after 1990. We do not know what caused the decline or extinction of their populations, even though...

Mountain chains and rivers are often found to represent barriers promoting vicariant differentiation in terrestrial vertebrates. Previous studies have supported the idea that the Cordillera de Mérida (CM), the easternmost branch of the Northern Andes, represents a geographic barrier for vertebrates, including frogs. Previous studies have also sugge...

Anthropogenic trade and development have broken down dispersal barriers, facilitating the spread of diseases that threaten Earth's biodiversity. We present a global, quantitative assessment of the amphibian chytridiomycosis panzootic, one of the most impactful examples of disease spread, and demonstrate its role in the decline of at least 501 amphi...

Species diversity in collared frogs of the genus Mannophryne is presumed to be underestimated due to the paucity of external morphology characters, but combining morphology with bioacoustics and other lines of evidence has shown to be useful in delimiting species of this group. Herein we describe a new species of Mannophryne from Sierra de Aroa in...
