Variación estacional del contenido de alginatos en tres especies de feofitas de Baja California Sur, México [PDF]

open access: yes, 1985
Se estudió la variación estacional del contenido de alginatos de Macrocystis pyrifera (L.) C. Agardh, Sargassum sinicola Setchel y Gardner y Eisenia arborea Areschoug, tres especies de feofitas de Baja California Sur; en las dos primeras se encontró una ...

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.

open access: yesWildlife 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

open access: yesBiotropica, 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

open access: yesNew 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

open access: yesFunctional 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

open access: yesJournal 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

open access: yesFunctional 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 ...

Forest cover drives bird occupancy across guilds and habitats in a Colombian coffee‐farming landscape

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Increasing landscape forest cover would improve occupancy for nearly all bird guilds using coffee and forest habitats in the Eastern Colombian Andes. Conserving forest and enhancing shade coffee are complementary–not interchangeable–strategies: landscape forest cover shapes the conditions under which farm‐scale habitat management can sustain diverse ...
