Movement Strategies of Neotropical Nectarivorous Birds: Insights From High‐Andean Hummingbirds and Flowerpiercers

Biotropica, Volume 58, Issue 1, January 2026.
Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

White‐tailed deer habitat use and implications for chronic wasting disease transmission Uso del hábitat del ciervo de cola blanca e implicaciones para la transmisión de la caquexia crónica

Wildlife Monographs, Volume 217, Issue 1, July 2025.
White‐tailed deer habitat use, activity, and attraction to conspecifics is highly variable between sexes and seasons. In this study, we leverage an unprecedented dataset from Wisconsin to illustrate how deer respond to changing physiological and social needs through the course of year.

The Unstable Relationship Between Drought Status and Leaf Water Content Complicates the Remote Sensing of Tree Drought Stress

Global Change Biology, Volume 31, Issue 4, April 2025.
Remote sensing can monitor plant drought stress across ecosystems but is limited by uncertain links between physiological stress and measurements of water content. We examined how water potential and water content, measured in the field, laboratory, and via airborne imaging, vary over time and space in two oak species.

Microclimatic variation regulates seed germination phenology in alpine plant communities

Journal of Ecology, Volume 113, Issue 1, Page 249-262, January 2025.
This study combines novel laboratory experimentation based on detailed field microclimatic data to tackle the understudied topic of germination phenology in alpine habitats. The findings suggest a predictable phenological shift in the germination of alpine plants along microclimatic gradients.
