Light use efficiency in pure and mixed Eucalyptus and Acacia mangium plantations with different stocking densities [PDF]
Competition for light in mixed-species plantations is a main limiting factor for tree growth. Understanding the light absorption and light use efficiency for each species at different planting densities and spatial arrangement of trees is essential for ...

Influência do sítio no desenvolvimento do Pinus taeda L.aos 22 anos: estado nutricional das plantas. [PDF]
A análise de solo, freqüentemente usada na agricultura, tem provado ser pouco útil em prever o crescimento de espécies florestais pela dificuldade em determinar com precisão a camada do solo de maior absorção dos nutrientes para a amostragem.

Fungos endofíticos associados a acículas de Pinus taeda [PDF]
O presente trabalho objetivou estudar os fungos endofíticos em acículas de árvores jovens de Pinus taeda L. e avaliar o efeito da posição de coleta na árvore. As amostras foram coletadas em duas alturas (30-50 cm e 100-130 cm acima do solo) e nas quatro posições cardeais (norte, sul, leste e oeste), em plantas com 18 meses de idade, localizadas em ...

Multi‐scale maternal behavioral responses by white‐tailed deer to coyote predation risk
In the piedmont region of the southeastern US, white‐tailed deer adjust maternal care strategies in response to variation in risk of encountering coyotes. In areas frequented by coyotes, adult female deer (i.e., does) increase their use of space, likely to avoid drawing coyotes to the location where a fawn is hidden.

In some portions of the southeastern United States where white‐tailed deer populations are declining, alteration of adult female harvest levels and the availability of alternative foods for coyotes can help increase population growth. Abstract White‐tailed deer (Odocoileus virginianus) populations in the southeastern United States have declined from ...

Insecticidal properties of Pinus taeda essential oil
This study aimed to evaluate the yield of essential oil extracted from different sample and pH compositions, as well as the insecticidal potential of Pinus taeda essential oil. For this, samples composed only of needle and composed of needle and branches were kept in solvent water at different pH (3, 4, 5 and 6). Subsequently, the oils extracted in the

Abstract Most of Earth's present‐day terrestrial surface is covered by regolith—the layers of soil, saprolite, and weathered bedrock that together comprise the critical zone. Recent research has focused on understanding fluxes of minerals, water, and energy through the critical zone under steady state assumptions.
