A total 59 herpetological taxa were recorded for immediate surroundings. These include 11 amphibians, belonging to nine genera seven different families, 48 reptiles, 32 12 families. Of these, reptiles are strictly endemic, making richest region Africa respect strict endemics, per 127 km 2 .

The highlands of the Guiana Shield (Pantepui) in northern South America harbor a unique fauna and flora. However, this diversity remains poorly documented, as many Pantepui massifs remain little explored or unexplored, mainly because their access is very challenging. Considering amphibians, 11 genera are endemic sub-endemic to Pantepui, one them, Neblinaphryne, monospecific was recently described from Neblina massif, at border between Brazil Venezuela. We undertook an expedition nearby, previously uninventoried Imeri massif discovered new species genus. describe herein Neblinaphryne imeri sp. nov., combining molecular, external morphological, acoustic, osteological myological data. shares with other (N. mayeri) minuscule septomaxillae pointed terminal phalanges, confirming morphological diagnostic characters Nevertheless, can promptly be distinguished N. mayeri by having head wider than long, distinct color pattern, prominent tubercles on eyelid humeral region, well genetic differences. These two likely respective massifs, providing striking example speciation isolation within which possibly mediated climate elevation, hypothesized for lineages region.

Abstract Background Few animal populations have been studied under the framework of OCBIL theory, which addresses ecology and evolution biodiversity on old climatically buffered infertile landscapes. Available genetic data challenge low connectivity high differentiation predicted for isolated tepui-summit vertebrate communities, suggesting potential dispersal among summits. However, theory posits reduced dispersibility, enhanced resilience to habitat fragmentation inbreeding due small populations. We tested these hypotheses by conducting first analytic evaluation spatial population biology a at multiple scales. Results used harmonic radar tracking (100 individuals/448 points contact) capture-mark-recapture (596 individuals captured/52 recaptured) reveal temporal niche, microhabitat use, size, abilities endemic toad Oreophrynella quelchii Roraima-tepui. Abundance was determined using closed model incorporating sources variation in capture probability. relative influence biotic abiotic variables distances moved through selection. Our indicate that size O. is remarkably large (ca. 12 million individuals), with strong seasonal demographic fluctuations. Ecology observed limited movements likelihood active tepui tops this species. results are counter those available but support two theory: dispersibility resilience. they do not expectation refugial size. Conclusion postulate insular, hostile environment tends produce robust populations, likely buffer stochastic adverse environmental effects, rather than diversity, as much younger post-Pleistocene Neotropical draw attention value faunal studies an better understand unique biota worldwide.
