Extreme Environmental Heat Stress in Costa Rica
(1989-07-16)
Five years of meteorological records were manually tabulated and analyzed for the estimation of the maximum WBGT (an environmental heat stress index) values that could be expected at different times of the day in three ...
Scrotal thermography and doppler ultrasonography of the testicular artery of buffaloes subjected to environmental heat stress
(2013-12-01)
The process of spermatic division and differentiation (spermatogenesis) occurs with intratesticular temperature lower that the corporal temperature and for that is essential that the testicular thermoregulation mechanism ...
Thermoregulatory responses of Alpine goats during thermal stress
(Amer Soc Agricultural Engineers, 1997-01-01)
Eight non-lactating Alpine goats, averaging 57kg, were paired according to weight and assigned randomly to 2 groups of 4 animals, control (CG) and treatment (TG) with feed and water ad libitum. An adjustment period of 7 ...
Influence of the environment on behavior patterns of laying hens kept in cages
(2008-12-01)
The aim of this paper is to verify the correlation between environmental indicators and behaviors expressed by laying hens kept in cages. The birds react to a severe environment through their behaviors, end the behaviors ...

Tolerance of an invasive plant in a copper saturated environment: Local adaptation as an evolutionary response?
(2015)
Human disturbance associated with mining activity can lead to accumulation of certain metals in
the environment, and these metals can limit plant growth and survival. Faced with these new
environmental conditions, the ...
