Adjustment of the reproductive activity of vulnerable lizard phymaturus williamsi at high altitudes
(Herpetological Conservation and Biology, 2018-04-30)
In environments with cold climates, reproduction of lizards is restricted to short seasonal periods of activity, from mid-spring to early autumn. We studied the reproductive biology of Phymaturus williamsi (William’s Andean ...
Dynamics of energy reserves and the cost of reproduction in female and male fiddler crabs
(Elsevier Gmbh, 2018-02)
The physiological costs of reproduction can be measured as the energy allocated to reproductive activities. In fiddler crabs, females allocate energy to vitellogenesis and brooding, whereas males perform expensive courtship ...
Life on the edge: Incubation behaviour and physiological performance of squat lobsters in oxygen-minimum conditions
(Inter-Research, 2019-07)
Squat lobsters frequently inhabit low-oxygen waters, facing particular physiological challenges. Pleuroncodes monodon inhabits one of the most extreme oxygen minimum zones in the world’s oceans at low temperatures, but ...
Photoperiodic modulation of reproductive physiology and behaviour in the cichlid fish Cichlasoma dimerus
(Pergamon-Elsevier Science Ltd, 2010-03)
Timing of breeding to an optimal season is a requirement for a successful reproductive outcome in seasonally breeding species. Photoperiodic signals are capable of modifying the reproductive behaviour and reproductive ...
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 ...
