Differential effects of foraging strategies on carotenoid‐derived plumage color and individual quality in stripe‐tailed yellow finches

Journal of Avian Biology, Volume 2025, Issue 2, March 2025.
Carotenoid‐based plumage color is crucial in avian mate selection, often serving as an indicator of individual quality. To determine whether carotenoid‐derived color can be a sign of individual condition and if there is a relationship between an individual's condition and color production, it is necessary to identify how carotenoids are acquired by ...

Tree species controls over nitrogen and phosphorus cycling in a wet tropical forest

Ecological Monographs, Volume 95, Issue 1, February 2025.
Abstract Wet tropical forests play an important role in the global carbon (C) cycle, but given current rates of land‐use change, nitrogen (N) and phosphorus (P) limitation could reduce productivity in regenerating forests in this biome. Whereas the strong controls of climate and parent material over forest recovery are well known, the influence of ...

Non‐native invasive plants in tropical dry forests: a global review of presence, impacts, and management

Restoration Ecology, Volume 33, Issue 1, January 2025.
Tropical dry forests (TDF) are among the most‐threatened terrestrial ecosystems, experiencing ongoing conversion to agricultural fields, pasture, and human settlements. Human disturbances are often precursors to invasion of ecosystems by non‐native species, but research on invasion patterns in tropical ecosystems is sparse, and there is no ...

Farming cattle in the tropics: Transnational science and industrializing pastures in Brazil

PLANTS, PEOPLE, PLANET, Volume 6, Issue 5, Page 1060-1069, September 2024.
Society is increasingly concerned over the environmental impact of diets. Much of this concern is over the environmentally destructive nature of meat production, especially beef and especially in the Amazon. This article aims to understand the production of beef in Brazil through the understudied perspective of forage grasses.
