Variabilidade do conforto térmico de aves de corte nas condições de ambiente natural em Chimoio - Moçambique

Research, Society and Development, 2022
O objetivo do trabalho foi calcular índices de conforto térmico para ambiente natural de aves de corte na cidade de Chimoio, província de Manica – Moçambique. A partir de dados médios mensais da temperatura do ar e da umidade relativa, foi calculado Índices de Temperatura e Umidade (ITU) para diferentes fases de vida das aves.

Complex relationship between soil fungi and conservation value assessments in boreal forests

Conservation Biology, Volume 39, Issue 4, August 2025.
Abstract Large‐scale industrial forestry is a threat to biodiversity and imposes long‐lasting changes to many forested biomes. Preserving forests as reserves is an important component of the strategy for safeguarding forest biodiversity. Yet, the selection of forests of high biodiversity value is usually based on proxies (i.e., subsets of aboveground ...

Climatic and Edaphic Drivers of Soil Organic Carbon and Pyrogenic Carbon Stocks Across Elevation and Disturbance Gradients in Colombian Andean Forests

Global Change Biology, Volume 31, Issue 7, July 2025.
This study examined soil organic carbon (SOC) and pyrogenic carbon (PyC) stocks in tropical Andean soils across elevation and disturbance gradients in Colombia. SOC stocks to 100 cm depth averaged 433.10 Mg C ha−1 while PyC was 34.13 Mg C ha−1. Key drivers of PyC stocks include soil clay (%), mean annual precipitation (PA), pH, Ca, and NDVI, which ...

Thermal tolerance is linked to anatomical but not morphological leaf traits in woody species of Andean tropical montane forests

Functional Ecology, Volume 39, Issue 6, Page 1537-1549, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The world is experiencing a rise in global temperatures as a result of climate change. Higher temperatures along with more frequent heat waves negatively impact physiological levels and ultimately lead to plant death.

Coupling between the environment and the pelagic resources exploited off northern Chile: ecosystem indicators and a conceptual model Acoplamiento entre el ambiente y los recursos pelágicos explotados en el norte de Chile: un modelo conceptual

Latin American Journal of Aquatic Research, 2008
The eastern boundary of the Chile-Peru Current System constitutes one of the most biologically productive ecosystems in the world, due largely to coastal upwelling and the horizontal advection of nutrients.

Differential responses of community‐level functional traits to mid‐ and late‐season experimental drought in a temperate grassland

Journal of Ecology, Volume 112, Issue 10, Page 2292-2306, October 2024.
These findings suggest that functional trait composition of grassland communities may shift under climate change‐induced drought, depending on the growing season timings. Trait‐based attempts to predict ecosystem functioning must account for such temporal variation in community trait values.
