Effects of Warming on Growth and Leaf Colonization by Litter Mat‐Forming Fungi in a Wet Tropical Forest in Puerto Rico

Biotropica, Volume 58, Issue 3, May 2026.
We took advantage of a long‐running field warming experiment, the Tropical Responses to Altered Climate Experiment (TRACE) located in the Luquillo Experimental Forest in Puerto Rico to evaluate the effects of +4°C warming on relative growth rates (RGR) and time to leaf colonization of a recently senesced leaf for drought‐tolerant species Marasmius ...

Local climate and genetic influence on intraspecific variation in torpor physiology of a cave‐roosting bat

Functional Ecology, Volume 40, Issue 4, Page 857-867, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...

AMPLIAÇÃO DO CALENDÁRIO DE SEMEADURA DA SOJA NO RIO GRANDE DO SUL PELO USO DE CULTIVARES ADAPTADOS AOS DISTINTOS AMBIENTES

Pesquisa Agropecuária Gaúcha, 2000
A época de semeadura é, provavelmente, a prática cultural isoladamente mais importante para a soja [Glycine max (L.) Merrill]. A melhor época de semeadura para esta oleaginosa depende, principalmente, da temperatura do solo para a germinação e emergência,

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

New Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

SOIL TEMPERATURE MODIFICATIONS CAUSED BY SOLARIZATION IN NURSERIES

Ciência Rural, 1993
Solarization effects on soil temperature were evaluated during the autumn. The increase in soil temperature caused by the use of transparent polyethylene (PE) low tunnels over solarized nurseries, in subtropical central region of the Rio Grande do Sul ...

Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams

Austral Ecology, Volume 51, Issue 3, March 2026.
Multi‐scale drivers of aquatic insect communities in Cerrado streams. The gradient (from left to right) indicates increasing spatial scale, showing that abundance is influenced by local factors (conductivity, temperature), taxonomic richness responds to agricultural land use at an intermediate scale, and community composition is structured by regional ...

Características térmicas do solo observadas em cidades distintas do estado da Paraiba

Revista Verde de Agroecologia e Desenvolvimento Sustentável, 2013
A variação da temperatura do solo que uma planta consegue suportar é relativamente ampla, no entanto, seu desenvolvimento é seriamente comprometido a partir do momento em que solo passa a assumir temperaturas abaixo ou acima de certos valores limites ...
