Abstract Mediterranean ecosystems are predicted to undergo longer and more intense summer droughts. The mechanisms underlying the response of herbaceous communities to such drier environments should be investigated to identify the resilience thresholds of Mediterranean rangelands. A 5‐year experiment was conducted in deep and shallow soil rangelands of

Bat winter foraging habitat use in working forests: a multispecies spatial occupancy approach
We examined winter occupancy and foraging habitat associations of bats in working pine forests of the southeastern United States Coastal Plain using acoustic detection. Although responses varied among species, we found that sites with high proportions of contiguous forest and low levels of basal area had higher bat community richness and species ...

Prototipo compactador de forraje
Uno de los problemas que enfrenta la ganadería en México es la escasez de alimento en la temporada de sequía. El ensilado es una de las actividades que soluciona ésta problemática. Para este fin se diseñó y construyó en el Departamento de Ingeniería Mecánica Agrícola de la Universidad Autónoma Chapingo, un prototipo para el compactado del forraje ...

Influence of microclimate and forest management on bat species faced with global change
Abstract Climate refugia, areas where climate is expected to remain relatively stable, can offer a near‐term safe haven for species sensitive to warming temperatures and drought. Understanding the influence of temperature, moisture, and disturbance on sensitive species is critical during this time of rapid climate change.

Densidad de siembra del girasol forrajero
Con el objetivo de promover el girasol como un cultivo forrajero, se evaluó el efecto de 4 densidades de siembra (75.000, 100.000, 125.000 y 150.000 plantas.ha-1) en el rendimiento de forraje para consumo de ganado.

Connectivity conservation planning through deep reinforcement learning
Abstract The United Nations has declared 2021–2030 the decade on ecosystem restoration with the aim of preventing, stopping and reversing the degradation of the ecosystems of the world, often caused by the fragmentation of natural landscapes. Human activities separate and surround habitats, making them too small to sustain viable animal populations or ...
