The effects of sand temperature on pre-emergent Green Sea Turtle hatchlingsEfecto de la temperatura de la arena en los días previos al emergimiento de neonatos de Tortuga Verde Marina
(Herpetological Conservation and Biology, 2010-08)
La temperatura de la arena puede desempeñar un rol importante en la supervivencia de neonatos de tortugas marinas. Altas temperaturas de la arena podrían inhibir la coordinación muscular en el proceso de ascenso hacia la ...
The identity of a controversial Neotropical turtle hatchling (Reptilia: Testudines: Chelidae)
(Society for the Study of Amphibians and Reptiles, 2015-12)
The purpose of this paper is to set the correct identity of a hatchling chelid turtle, purportedly the southernmost record of Mesoclemmys vanderhaegei (Bour), whose identification has been doubted repeatedly. This specimen ...
Incubation Temperature during Fetal Development Influences Morphophysiological Characteristics and Preferred Ambient Temperature of Chicken Hatchlings
(Public Library Science, 2016-05-16)
Skin and feather characteristics, which play a critical role in body temperature maintenance, can be affected by incubation circumstances, such as incubation temperature. However, no study to date has assessed the influence ...
Chicken hatchlings prefer ambient temperatures lower than their thermoneutral zone
(Elsevier B.V., 2014-10-01)
We investigated whether or not the preferred ambient temperature (Tapref) of the 1-day old chicken hatchling, a precocial neonate with excellent locomotory capacity, clearly identifiable thermogenesis and independence from ...

Sex differences in the genitalia of hatchlings Caiman latirostris (Daudin, 1801)
(Society for the Study of Amphibians and Reptiles, 2010-06)
To date the discrimination of newly hatched caiman into malesand females has not been possible by observing the externalgenitalia. We show that such separation can be achieved fromsimple measures that can be recorded on ...

Maternal Lipid Provisioning Mirrors Evolution of Reproductive Strategies in Direct-Developing Whelks
(UNIV CHICAGO PRESS, 2016)
The energetic input that offspring receive from their mothers is a well-studied maternal effect that can influence the evolution of life histories. Using the offspring of three sympatric whelks: Cominella virgata (one ...
Thermogenesis, vocalization, and temperature preference of 1-day-old chicken hatchlings after cold-exposure in late embryogenesis
(Springer, 2014-07-01)
In a thermal gradient the preferred ambient temperature (T (a) pref) of chicken hatchlings is a few degrees lower than thermoneutrality. To investigate whether a correlation may exist between T (a) pref and the autonomic ...
