Abstract Biodiversity loss is extreme in amphibians. Despite ongoing conservation action, it difficult to determine where we stand overcoming their extinction crisis. Among the most threatened amphibians are 131 Neotropical harlequin toads. Many of them declined since 1980s with several considered possibly extinct. Recently, more than 30 species have been rediscovered, raising hope for a reversing trend amphibian We use past and present data available toads ( Atelopus ), examine whether...
This study documents the current state of conservation knowledge on threatened amphibian species in Peru. Following International Union for Conservation Nature (IUCN) classification system, we considered following categories: Critically Endangered, Vulnerable, and Near Threatened. Even though only first three categories are regarded as by IUCN, included fourth category to make comparisons with list issued Peruvian government. We used Global Amphibian Assessment's database Peru this...
Life at high altitudes is particularly challenging for ectothermic animals like reptiles and involves the evolution of specialised adaptations to deal with low temperatures, hypoxia intense UV radiation. As a result, only very few reptile taxa are able survive above 5,000 m elevation herpetological observations from these exceedingly rare. We report here an exceptional observation lizard population (Liolaemus aff. tacnae; Reptilia, Squamata) Andes Peru. During ascent Chachani mountain (6,054...
Abstract Anthropogenic biodiversity loss is extreme in amphibians. Despite ongoing conservation action, it difficult to determine where we stand overcoming their extinction crisis 1,2. Extinction risk not equally distributed across amphibians 3-5. Among the most threatened are 131 Neotropical harlequin toads (Atelopus), many of which dramatically declined since late 1980s with several considered possibly extinct 5,6. Recently, more than 30 species have been rediscovered7, raising hope for a...
El género Liolaemus presenta una gran diversidad entre los tetrápodos actuales, al punto de corresponder segundo con mayor número especies válidas descritas del infraorden Iguania. En este trabajo, se describe nueva especie lagartija arenícola perteneciente subgénero Eulaemus, grupo montanus, procedente las lomas costeras Quilca, La Chira y Ocoña, todos en la provincia Camaná, departamento Arequipa, Perú. Para determinar el estatus taxonómico esta especie, analizamos caracteres morfológicos,...
The southwestern Andes of Peru harbor a hidden taxonomic diversity reptiles. We describe new species Liolaemus Wiegmann (Iguania: Liolaemidae) from xerophytic environments the slopes Peru, 2,400-2,900 m asl. species, previously considered to be population L. insolitus Cei, exhibits unique diagnostic characters morphology, scalation and color pattern, molecular evidence that suggest it belongs in montanus group reichei clade. Moreover, is endemic eastern La Caldera batholith Department...
Antecedentes y Objetivos: En Perú, la conservación de los cactus está amenazada principalmente por expansión áreas agrícolas, minería, construcción carreteras, urbana el aumento población, ocasionando fragmentación destrucción hábitats. Los ecosistemas perturbados se podrían restaurar mediante uso semillas plántulas cactáceas. El objetivo este estudio fue evaluar efecto luz en germinación cactáceas peruanas. Métodos: Las fueron colectadas departamentos Ancash, Apurimac, Arequipa Huánuco....
Se describe una nueva especie de lagartija del grupo Liolaemus montanus, endemico lavertiente occidental los Andes, en la provincia Huaytara, departamento Huancavelica,Peru.

The Andes of southern Peru contain a biodiversity with high degree endemism due to itspeculiar geography and bioclimate. In this work new endemic species the genus Liolaemusis described which would be restricted an altitude between 3870–4100 m s.n.m., in theSalado river basin district province Espinar, department Cusco. This speciesis characterized by unique combination morphological characters color patternthat distinguish it from rest Liolaemus, mainly within L. ortiziclade montanus group,...
