Do lower air or water temperatures limit the southern distribution of the white mangrove Laguncularia racemosa in South America?
(2019-12-15)
Rising temperatures due to climate change are expected to drive shifts in species composition, phenological patterns and the productivity of mangrove trees. During early life history stages, such as dispersal and settlement, ...
Thermal tolerance and survival responses to scenarios of experimental climatic change: changing thermal variability reduces the heat and cold tolerance in a fly
(Springer, 2016)
Climate change poses one of the greatest threats to biodiversity. Most analyses of the impacts have focused on changes in mean temperature, but increasing variance will also impact organisms and populations. We assessed ...
Acclimation of broiler chickens to chronic high environmental temperature
(2004-02-01)
The present study was conducted to evaluate the zootechnical parameters and age related changes in physiological responses of broiler chickens exposed to hot environment from early age onwards. The broiler chickens were ...
Predator-prey interactions under climate change: the importance of habitat vs. body temperature.
(2009)
Habitat temperature is often assumed to serve as an effective proxy for organism body temperature when making predictions of species distributions under future climate change. However, the determinants of body temperature ...
Analysis of the Trends in Observed Extreme Temperatures in Mainland Chile Between 1966 and 2015 Using Different Indices
(Birkhauser Verlag AG, 2019)
Air temperature records provide strong evidence of change and variability in the climate system. The sensitivity of temperature to changes throughout the year renders it an ideal object of study when seeking to identify ...
Incubation and rearing temperature effects on Hsp70 levels and heat stress response in broilers
(Agricultural Inst Canada, 2003-06-01)
Incubation temperature (IT) was changed to evaluate if 6-wk-old birds become more tolerant to heat stress. After 13 d of incubation, 470 eggs were submitted to low (36.8degreesC), normal (37.8degreesC) and high (38.8degreesC) ...
The Mean and Variance of Environmental Temperature Interact to Determine Physiological Tolerance and Fitness
(UNIV CHICAGO PRESS, 2011)
Global climate change poses one of the greatest threats to biodiversity. Most analyses of the potential biological impacts have focused on changes in mean temperature, but changes in thermal variance will also impact ...
Evidence of climate change based on lake surface temperature trends in south central Chile
(MDPI, 2021)
Lake temperature has proven to act as a good indicator of climate variability and change.
Thus, a surface temperature analysis at different temporal scales is important, as this parameter
influences the physical, chemical, ...
Meteorological factors and childhood diarrhea in Peru, 2005-2015: a time series analysis of historic associations, with implications for climate change
(BioMed Central, 2021)
BACKGROUND: Global temperatures are projected to rise by ≥2 °C by the end of the century, with expected impacts on infectious disease incidence. Establishing the historic relationship between temperature and childhood ...
Attribution and projections of temperature extreme trends in South America based on CMIP5 models
(Blackwell Publishing, 2021-03)
Temperature extreme indices were analyzed for five continental regions of southern South America defined according to their climatic characteristics. Gridded observations, reanalysis, and global-coupled climate models from ...
