What do giant titanosaur dinosaurs and modern Australasian megapodes have in common?
(PeerJ, 2015-10)
Titanosauria is a globally distributed clade of sometimes extremely large Mesozoic herbivorous sauropod dinosaurs. On the basis of current evidence these giant dinosaurs seem to have reproduced in specific and localized ...
Effect of High Incubation Temperature on the Blood Parameters of Layer Chicks
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2016-10-01)
Adequate environmental temperature control is essential for incubation efficiency. Layer breeder eggs (n=360) were weighed and distributed in a completely randomized experimental design with two treatments, consisting of ...
Influence of a Commercial Hatchery Thermal Environmental on the Heat Loss of Fertile Broiler Eggs
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2016-10-01)
The objectives of this study were to monitor the thermal environment of different hatchery locations during the transfer of fertile eggs from the setter and to the hatcher, to measure egg heat loss, and to determine its ...
Production of Kluyveromyces spp. and environmental tolerance induction against Aspergillus flavus
(Inst Microbiologia, 2013-10)
The viability and biomass production of three isolates of Kluyveromyces spp. in six different growth media were studied. All yeast isolates showed good growth in all of the media tested, but nutrient yeast dextrose broth ...

Fire cues trigger germination and stimulate seedling growth of grass species from Brazilian savannas
(2019-01-01)
Premise: Although fire cues (high temperatures and smoke) influence seed germination in numerous species from fire-prone environments, their effects on seed germination of species from neotropical savannas are poorly ...
Factors affecting brood patch development in Magellanic Penguins Spheniscus magellanicus
(Polish Academy of Sciences. Museum and Institute of Zoology, 2016-05)
Brood patches allow the transfer of heat to eggs for their successful embryonic development, and in many species determine egg temperature during incubation. We investigated brood patch development of Magellanic Penguins ...
Vitamina C intra-ovo e estresse por calor na incubação de frangos de corte
(Universidade Estadual Paulista (Unesp), 2013-11-30)
Estresse calórico afeta o desempenho e as características morfofuncionais dos frangos. Manipulação das condições ambientais na fase fetal tem se mostrado efetiva na indução de características adaptativas ao calor na ...

Alterações celulares e moleculares induzidas pelo choque térmico em espermatozoides bovinos
(Universidade Estadual Paulista (Unesp), 2017-02-24)
A função do espermatozoide pode ser comprometida por condições ambientais adversas. Estudos já demonstraram que a exposição in vivo e in vitro de espermatozoides bovinos a temperatura elevada induz a morte celular, reduz ...
