Influencia de la temperatura y el tiempo de exposición sobre la germinación y la emergencia de Piptochaetium napostaense (Speg.) Hack.

Semiárida, 2020
El fuego no sólo afecta a la vegetación sino también al suelo donde se encuentra el banco de semillas, principal reservorio de propágulos con que cuenta Piptochaetium napostaense (Speg.) Hack. (“flechilla negra”) para su mantenimiento y regeneración.

Efeito do estresse térmico e do exercício sobre parâmetros fisiológicos de cavalos do exército brasileiro Effect of heat stress and exercise on physiological parameters of horses of the Brazilian army

Revista Brasileira de Zootecnia, 2002
Os cavalos do exército brasileiro são usados em dias de exposição e, muitas vezes, submetidos a exercício intenso, que, aliado às condições climáticas do cerrado do Centro-Oeste brasileiro, resulta na necessidade de extrema aclimatação dos mesmos.

A link between increased temperature and avian body condition in a logged tropical forest

Conservation Biology, EarlyView.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Produção e composição do leite de porcas híbridas mantidas em ambiente quente Production and composition of milk of hybrid sows maintained in hot environment

Ciência Rural, 2007
Foram avaliados os efeitos da ordem de parto e do estágio de lactação sobre a produção e composição do leite de matrizes suínas híbridas mantidas em ambiente quente (± 28,5°C). Foram utilizadas 36 fêmeas de 1, 2, 3 e ³4a ordem de parição,

Nearest-Neighbour and Non-Nearest-Neighbour Non-Covalent Interactions between Substituents in the Aromatic Systems: Experimental and Theoretical Investigation of Functionally Substituted Benzophenones

Molecules, 2022
Benzophenone derivatives exhibit not only biological activity but also act as photo initiator and UV blocker. We carried out experimental and theoretical thermochemical studies of hydroxy- and methoxy-substituted benzophenones.

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

Conservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Breeding in natural nesting sites can improve the resilience of local Lesser Kestrel (Falco naumanni) populations to environmental changes

Ibis, EarlyView.
The identification of key habitats of threatened species and of extrinsic environmental factors that influence their resilience to human‐induced environmental changes are the foundation for the definition of conservation objectives. Using the presence and numerical abundance data collected in a long‐term survey (2000–24) of breeding colonies of Lesser ...

On thermodynamical work and heat definitions and their consistency regarding the second law

Revista Brasileira de Ensino de Física
We start by presenting an overview of the various definitions of heat and work found in the literature. Then, we consider several examples for analysis and show that the theory of Thermodynamics requires a precise definition of such quantities.

Mosquito and arbovirus surveillance in wetlands of South‐East England: Comparison of two adult mosquito traps, use of a novel trap with FTA™ cards and arbovirus testing

Medical and Veterinary Entomology, EarlyView.
Trap performance: Mosquito Magnet® captured significantly more mosquitoes overall, while BG‐Sentinel showed greater species evenness and was more effective for Culex pipiens s.l. and broader species representation. Spatial variation: Mosquito abundance and species composition varied significantly between wetlands, highlighting the importance of site ...
