Environmental sex determination and sex chromosomes are distributed throughout reptilian phylogeny, suggesting independent evolutionary losses and gains, but conserved mechanisms are known for crocodilians (temperature) and birds (chromosomal sex determination) (Olmo, 1990; Ewert and Nelson, 1991; Pieau et al, 1999; Shine, 1999; Nanda et al, 2000; Nanda and Schmid, 2002).
Others are environmental data she's collated from where she's been living, anything from tidal changes due to the sun and moon and ocean and land temperatures, to the relationship between barometric pressure, cloud cover, soil temperature readings, and bird sightings.
With their hot body temperatures, mammals and birds suffer from few fungal diseases save those confined to the coolish epidermis.
We used this as our dependent variable and ran a general linear model with temperature as a covariate and bird as a random factor (Barnett et al. 2012).
The hydration state of montmorillonite changes also with effective pressure and temperature (Bird 1984; Colten-Bradley 1987), meaning it is important to understand how hydration state influences the frictional strength of montmorillonite with depth.
Different homeothermic vertebrates can also show up to 5°C difference in body temperature, with dolphins and whales having a body temperature of 36°C and birds 41°C.
There is no evidence that body temperature of mammals and birds is adaptive to the different climates, either of great heat or cold.
Numerical results are validated against experimental data and further investigations are carried out to study the influence of environmental temperature, impact location on windshield and bird impact velocity.
Variations in pollutant concentrations at the exhaust fans were affected by outdoor temperature, ventilation, bird condition, and farm operation.
