Living in an area chronically polluted with metals is usually associated with changes in the energy distribution in organisms due to increased energy expenses associated with detoxification and excretion processes. These expenses may be reflected in the available energy resources, such as lipids, carbohydrates, and proteins. In this context, the en...

To address the question about costs of living in polluted areas, biomarkers linked to metabolism were measured in Pterostichus oblongopunctatus (Coleoptera: Carabidae) collected along two metal-pollution gradients in the vicinity of the two largest Polish zinc smelters: 'Bolesław' and 'Miasteczko Śląskie' in southern Poland. Both gradients covered...

Efficient monitoring of biodiversity-rich areas in conflict-affected areas with poor rule of law requires a combination of different analytical approaches to account for data biases and incompleteness. In the upland Amazon region of Venezuela, in Canaima National Park, we initiated biodiversity monitoring in 2015, but it was interrupted by the esta...

Camera trapping has revolutionized wildlife ecology and conservation by providing automated data acquisition, leading to the accumulation of massive amounts of camera trap data worldwide. Although management and processing of camera trap‐derived Big Data are becoming increasingly solvable with the help of scalable cyber‐infrastructures, harmonizati...

The figure Conserved Area is a category of environmental protection not legally established in Venezuela. This is an "effective area-based conservation measure" (OECMs) in which the IUCN has recognized private, communal, mixed, peasant or demarcated land for native ethnic groups and that are not part of protected areas. of the nation, in which the...

Para todos los autores y equipo editorial que nos unimos para realizar esta extraordinaria obra es un honor muy grande presentar este compendio sobre los Felinos de Venezuela que representa una publicación muy significativa para el conocimiento de este grupo animal tan importante.

The Garden Hunting hypothesis establishes that heterogeneous agroforestry landscapes maintain a species richness similar to that of virgin forests, but with a species composition dominated by herbivores. Here, camera trap surveys and spatially explicit interviews are combined on the extent and occurrence of indigenous Pemón hunting in a mosaic of s...

Background Human encroachment and overexploitation of natural resources in the Neotropics is constantly increasing. Indigenous communities all across the Amazon, are trapped between a population rise and a hot debate about the sustainability of hunting rates. The Garden Hunting hypothesis states that shifting cultivation schemes (conucos) used by A...

A new species of Protopedaliodes Viloria & Pyrcz, a satyrine butterfly genus endemic to the highest part of the Guyana Shield, P. arekuna Pyrcz & Stachowicz n. sp., is described from the summit area, ca. 2400 m, of Tramen Tepui, an isolated mountain situated on the Venezuela–Guyana border. It is a remarkable finding as it is probably a narrow endem...

The Gran Sabana is a region of great biogeographical and conservation value that has been recently threatened due to increasing overexploitation, of natural resources and illegal mining. Systematic survey methods are required in order to study species responses to landscape transformation. The main objectives of this study were: 1) to test the rela...

La reciente explosión de estudios con cámaras trampas, representan un gran desafío en la técnicas modernas de muestreo de la vida silvestre. Esta herramienta, ha complementado y en algunos casos, reemplazado, métodos tradicionales de muestreo como los transectos lineales, identificación de rastros, entrevistas a comunidades locales, observaciones d...

Habitat fragmentation, fire and hunting are among the most important anthropogenic disturbances that are a direct threat to wildlife and its conservation. They permanently affect the short-term dynamics of mammal’s population, their distribution and abundance and are of extreme importance for the conservation of biodiversity and natural resources o...

Habitat fragmentation, wildfire and hunting are anthropogenic disturbances that pose direct threat to wildlife and have gained increasing importance for conservation. Do some level of disturbances enhance biodiversity in the Gran Sabana of Venezuela? (Intermediate Disturbance Hipotesis, Conell 1987) Which mammals diet group tolerate habitat fragmen...

Density is crucial for understanding large carnivore ecology and conservation, but estimating it has proven methodologically difficult. We conducted 1 year of camera trapping to estimate jaguar (Panthera onca) density and population structure in the Los Llanos region of Venezuela on the Hato Piñero ranch, where hunting is prohibited and livestock a...

Two new species of diurnal moths of the genus Erateina (Geometridae, Larentiinae) are described from the table mountains of the Guiana Shield in the SE Venezuela. The genus is species rich, with 85 described and over 200 recognized species, but was so far known only from the Andes and the mountains of Costa Rica and Panama. This report extends...
