Effects of selective harvest on antler size of white‐tailed deer in Texas, USA
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Distribuição espacial de atributos físicos do solo em área cultivada com cana-de-açúcar.
O conhecimento da variabilidade dos atributos do solo é essencial para a tomada de decisão das práticas de manejo a serem adotadas numa determinada área de cultivo e assim, estabelecer um plano amostral adequado.

Abstract In the years immediately following the Spanish Civil War, the political culture of Falangism developed a deeply gendered regenerationist discourse, which proposed that regeneration would only be possible if the nation recovered its virile attributes.

Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over
