There was described a new species for fish fauna of Western Podolian Prydnistrovya – stickleback Gasterosteus aculeatus Linnaeus, 1758 ( Gasterosteidae ). The changes of plastic and meristic characters, diet and propagation in comparison with other water bodies of Ukraine were studied. It was shown that present conditions of nonmigratory form of stickleback in waters of the region are favourable. There was made a conclusion on high possibility of further increase of the stickleback number and… Expand
Freshwater influence is associated with differences in bone mineral density and armour configuration in threespine stickleback (Gasterosteus aculeatus)
TLDR
Threespine stickleback (Gasterosteus aculeatus Linnaeus, 1758) exhibit a well-documented reduction in plate number associated with adaptation to freshwater environments, and this work tested the hypothesis that this reduction is related to climate change. Expand
Using predator models to induce anti-predator behaviors in two captive tamarin (Callitrichidae) species at Parken Zoo
TLDR
Conclusions of predator models, particularly a stuffed fox, being an effective way of inducing anti-predator behaviors in these tamarin species could be made, although warnings for possible habituation effects should be issued. Expand
Hormonal and fitness consequences of behavioral assortative mating in the convict cichlid (Amatitlania siquia).
TLDR
Investigation of the link between partner behavioral assortment and their hormonal response to the pairing context suggests hormonal adjustment within pairs in this species of convict cichlid. Expand
Response of New Zealand birds to the presence of novel predators
TLDR
The results support the importance of historical and ontogenetic factors in influencing how predator recognition and personality traits are expressed and confirm that at least some native birds can develop recognition of novel predators. Expand
Are there consistent behavioral differences between sexes and male color morphs in Pelvicachromis pulcher?
TLDR
Red males are hypermasculinized as predicted with respect to aggressive behavior and activity levels, but not all behaviors follow this pattern and there is no evidence for a common behavioral syndrome underlying personality traits across females, yellow males and red males. Expand
Validation of water-borne steroid hormones in a tropical frog (Physalaemus pustulosus).
TLDR
The findings indicate that sampling water-borne hormones presents a non-invasive and biologically informative approach that will be useful for behavioral endocrinologists and conservation physiologists. Expand
Association between pituitary adenylate cyclase-activating polypeptide and reproduction in the blue gourami.
TLDR
It is proposed that in the blue gourami, PACAP is involved in the final oocyte maturation stage in females, whereas in males, it is associated with sexual behavior. Expand
Mate choice, parental care and foraging behaviour of the northern trout gudgeon, Mogurnda mogurnda (Pisces : Eleotridae)
TLDR
This study focuses on mate choice in the Northern Trout GUDGEon, which is concerned with female choice and male competition, and the consequences of these choices on offspring selection and energy gain. Expand
eview nvironmentally induced oxidative stress in aquatic animals
Reactive oxygen species (ROS) are an unenviable part of aerobic life. Their steady-state concentration is a balance between production and elimination providing certain steady-state ROS level. TheExpand
Environmentally induced oxidative stress in aquatic animals.
TLDR
The general processes responsible for ROS generation in aquatic animals are described and the identification of its general characteristics and mechanisms responsible for adaptation to the stress have been discussed. Expand
