Environmental detection of the amphibian chytrid fungus in water bodies is associated with host infection along a deforestation gradient

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Linking environmental pathogen detection with host infection patterns can improve surveillance of diseases involving environmental transmission, particularly where direct host sampling is logistically challenging. This approach enables the identification of areas of elevated transmission risk and supports targeted monitoring and management under ...

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars

Functional Ecology, Volume 40, Issue 5, Page 1475-1490, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Choice of grazed herbage or maize silage by lactating dairy cows: influence of sward height and concentrate level Preferência por pastagem ou silagem de milho por vacas leiteiras em lactação: influência da altura do pasto e do nível de concentrado

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
The preference of lactating dairy cows for grazed herbage or maize silage (MS), simultaneously offered ad libitum in the field, was examined at two sward heights (SH 4-6 and 8-10cm) and two concentrate levels (CL 0 and 6kg day-1) in a 2x2 factorial ...

Beyond Ecology: How Environmental and Social Landscapes Shape Tropical Forest Restoration in Southeast Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Restoration was more associated with environmental variables than socioeconomics. Active restoration was utilized in degraded areas and pasture abandonment favored natural regeneration. Successful tropical restoration is dependent on a complex interdependent mix of factors.

EVENTOS PLUVIOMÉTRICOS CONCENTRADOS NO ESPAÇO URBANO

Observatorium: Revista Eletrônica de Geografia, 2019
O intenso processo de urbanização pelo qual passou o Brasil nas últimas décadas, culminou num crescimento desordenado da maioria das cidades brasileiras. Tal processo resultou em vários problemas associados ao planejamento inadequado da ocupação do espaço urbano, intensificando a ocorrência de enchentes provocadas por eventos pluviométricos intensos ...

Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...
