ESTRUCTURA DE RODALES DE Pinus hartwegii AFECTADOS POR INCENDIOS UTILIZANDO PARÁMETROS DE VECINDAD EN LA SIERRA MADRE ORIENTAL, MÉXICO

Tropical and Subtropical Agroecosystems, 2012
<p>The objective of this research was to characterize the pattern of spatial structure of a <em>Pinus hartwegii</em> forest in the Sierra Madre Oriental, affected by a fire in 1998. Sampling was stratified by fire severity. Three fire severity classes were defined based on the degree of crown consumption (low, medium and high).

Knee height is often right: evaluating device height effects on camera trapping rate

Remote Sensing in Ecology and Conservation, EarlyView.
Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, EarlyView.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Parámetros genéticos de caracteres de interés agronómico en cuatro poblaciones espontáneas de Pappophorum vaginatum (Poaceae) en la región semiárida de la provincia de Buenos Aires, Argentina

Lilloa, 2021
En Argentina, más específicamente en los pastizales del sur de la provincia fitogeográfica del Monte, Pappophorum vaginatum Buckley es prácticamente la única especie que provee forraje para los animales durante el verano. Debido a esto, se necesitan estudios orientados a lograr la mejora genética en esta especie que combine los efectos de la selección ...

Monitoring wildlife health for diseases with visible signs by integrating camera traps with marked individuals

Conservation Biology, EarlyView.
Abstract Monitoring wildlife health is essential for conservation and management, wildlife and livestock welfare, and public health in a One Health framework. Yet, wildlife health monitoring often requires long‐term fieldwork and intensive sampling, which can be costly or logistically challenging, especially for remote, rare, or elusive populations. To
