Network dynamics revealed from eDNA highlight seasonal variation in urban mammal communities. [PDF]

J Anim Ecol
Our novel study applied eDNA to track seasonal shifts in urban mammal communities, revealing changes in diversity and species interaction networks across 21 urban parks in Detroit. We highlight the influence of park size and human activity on biodiversity, demonstrating the utility of eDNA for urban conservation and wildlife management.

Tracking Small Animals in Complex Landscapes: A Comparison of Localisation Workflows for Automated Radio Telemetry Systems. [PDF]

Ecol Evol
Automated radio telemetry grids provide the possibility of studying movement of small animals at very fine spatial scales, but the influence of rugged terrains and vegetation on localisation error curtails the applicability of this technology. In this study, we present a comparative workflow to reduce error and show how selecting higher radio signal ...

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, Volume 226, Issue 1, September 2026.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Soundscapes of the Upper Amazon: Seasonal Activity Patterns of Insectivorous Bats in Cordillera Escalera, Peru

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Bats, the second most diverse group of mammals, play essential ecological roles in insect control, pollination, and seed dispersal. In Peru, insectivorous bats remain poorly studied, particularly in high‐elevation rainforest ecosystems of the upper Amazon region.

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

New Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Wood anatomical trait correlations with hydraulic efficiency and safety in an aseasonal wet tropical forest

Functional Ecology, Volume 40, Issue 8, Page 2701-2717, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Xylem anatomy underpins the capacity of trees to transport water while avoiding hydraulic failure, shaping species performance and resilience to climate change. However, the specific ways anatomical traits underpin hydraulic trade‐offs in tropical forests remain debated.

High and dry: Environmental conditions drive opportunities for disease transmission in desert bighorn sheep

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
By using probabilistic models to predict contacts as a function of spatially and temporally varying environmental conditions, we show that population‐level conditions at the time of disease introduction can structure opportunities for transmission within each population.

How vulnerable are amphibians to climate change? A mechanistic perspective

Functional Ecology, Volume 40, Issue 6, Page 1550-1560, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Amphibians are frequently identified as highly vulnerable to climate change, yet the mechanisms driving this sensitivity remain uncertain. Approaches that explicitly link physiological mechanisms to environmental variation provide powerful tools for forecasting climate ...

Estimación del régimen de precipitación a partir de la distancia a la cordillera en el noroeste de la Patagonia

Ecología Austral, 1995
Se elaboraron modelos de regresión para el sector NO de Chubut (16000 km2 ) que permiten estimar la precipitación media anual y estacional y el coeficiente de variación interanual a partir de la distancia a la cordillera de los Andes.
