New insights into reproductive physiology in Antarctic fish: a trial in Lepidonotothen nudifrons
(Springer, 2021-06)
The spatio-temporal delimitation of fish reproduction is essential for the appropriate management and conservation strategies in populations. Assessing this feature in Antarctic Ichthyology is particularly difficult because ...
Dominance hierarchies and social status ascent opportunity: Anticipatory behavioral and physiological adjustments in a Neotropical cichlid fish
(Pergamon-Elsevier Science Ltd, 2012-07)
In this work we characterized the social hierarchy of non-reproductive individuals of Cichlasoma dimerus (Heckel, 1840), independently for both sexes, and its relationship to the opportunity for social status ascent. Female ...
Social and reproductive physiology and behavior of the Neotropical cichlid fish Cichlasoma dimerus under laboratory conditions
(Sociedade Brasileira de Ictiologia, 2011-09)
In this work we describe for the first time the social and reproductive behavior of the Neotropical fish Cichlasoma dimerus (Heckel, 1840) [Perciformes: Cichlidae], endemic to the Paraná River basin, using a comprehensive-integral ...
Ecotourism effects on health and immunity of Magellanic penguins at two reproductive colonies with disparate touristic regimes and population trends
(Oxford University Press, 2018-11)
Negative effects of ecotourism on wildlife are rising worldwide. Conservation physiology can play a major role in protecting wildlife by providing early alerts on changes in the status of individuals exposed to tourist ...
The South American Plains Vizcacha, Lagostomus maximus, as a Valuable Animal Model for Reproductive Studies
(JSciMed Central, 2016-10)
The vast majority of our understanding of the mammalianreproductive biology comes from investigations mainlyperformed in mice, rats and humans. However, evidencegathered from non-conventional laboratory models, farm andwild ...
Impacts of fisheries on elasmobranch reproduction: high rates of abortion and subsequent maternal mortality in the shortnose guitarfish
(Wiley Blackwell Publishing, Inc, 2019-04)
The fate of bycatch species released back into the water is crucial to estimate population status and consequent decisions to implement adequate management measurements for elasmobranchs. The shortnose guitarfish, Zapteryx ...
Aggressive behavior and reproductive physiology in females of the social cichlid fish Cichlasoma dimerus
(Pergamon-Elsevier Science Ltd, 2012-05)
The South American cichlid fish Cichlasoma dimerus is a freshwater species that presents social hierarchies, a highly organized breeding activity, biparental care and a high frequency of spawning. Spawning is followed by ...
Optimización del tratamiento térmico para la inducción al desove de Argopecten purpuratus (Mollusca: Bivalvia)
(Universidad de Valparaíso, 2021)
The effect of Glycoline® on reproductive efficiency in high-producing dairy cows
(Universidad de Córdoba, 2016)
Slow life histories in lizards living in the highlands of the Andes Mountains
(Springer Heidelberg, 2017-11-17)
In the highlands of the Andes, lizards must balance precisely the allocation of energy for growth and reproduction to ensure their survival. We studied the individuals’ age, growth rates, age at sexual maturity, and maximum ...
