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

Journal 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 ...

Evolution of Reproductive Plasticity in a Seasonal Tropical Environment

Ecology Letters, Volume 29, Issue 5, May 2026.
We reveal widespread occurrence of seasonal reproductive plasticity, including reproductive diapause, in Nymphalid butterflies in a seasonal rainforest in the Amazon. This highlights that, not only in temperate but also tropical habitats, seasonality is an important driver of plastic life history strategies. ABSTRACT Seasonality can drive the evolution

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

People and Nature, Volume 8, Issue 3, Page 782-796, March 2026.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

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.

High soil moisture triggers negative plant–soil feedbacks in a tropical forest

Functional Ecology, Volume 39, Issue 6, Page 1469-1482, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐microbial interactions help stabilize coexistence and shape ecological communities. These interactions are sensitive to abiotic conditions, but how they may be affected by environmental change is unknown.

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.
