Tadpole begging reveals high quality
(2017)
Parents can benefit from allocating limited resources non randomly among offspring, and offspring solicitation (i.e. begging) is often hypothesized to evolve because it contains information valuable to choosy parents. We ...
Discrimination of offspring by indirect recognition in an egg-feeding dendrobatid frog, Oophaga pumilio
(2009)
Offspring discrimination, the differential treatment of offspring and unrelated young, functions in numerous animal taxa to ensure that vital and costly parental care behaviours are appropriately directed. Discrimination ...
Empirical evidence for multiple costs of begging in poison frog tadpoles
(2018)
In recent decades, theoretical and empirical work has investigated the relative roles of costs and benefits in inhibiting excessive displays of begging to parents. Whether costs are important in maintaining reliability of ...
Interacting environmental stressors modulate reproductive output and larval performance in a tropical intertidal barnacle
(2015-07)
Tropical intertidal filter-feeding invertebrates often face thermal stress and oligotrophic nearshore conditions, which may modulate reproductive responses. In order to investigate how these stressors affect resource ...
Maternal dietary carotenoids mitigate detrimental effects of maternal GnRH on offspring immune function in Japanese quail (Coturnix japonica)
(Wiley, 2013-12)
Maternal resources deposited in eggs can affect the development of several offspring phenotypic traits and result in trade-offs among them. For example, maternal androgens in eggs may be beneficial to offspring growth and ...
Availability of a rich source of sodium during the perinatal period programs the fluid balance restoration pattern in adult offspring
(Pergamon-Elsevier Science Ltd, 2012-02)
Osmoregulatory mechanisms can be vulnerable to electrolyte and/or endocrine environmental changes during the perinatal period, differentially programming the developing offspring and affecting them even in adulthood. The ...
Availability of a rich source of sodium during the perinatal period programs the fluid balance restoration pattern in adult offspring
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Osmoregulatory mechanisms can be vulnerable to electrolyte and/or endocrine environmental changes during the perinatal period, differentially programming the developing offspring and affecting them even in adulthood. The ...
Sperm quality of spontaneously occurring gynogenetic males in the yellowtail tetra Astyanax altiparanae
(2021-01-01)
Gynogenesis is a chromosomal manipulation technique where an offspring is generated exclusively from maternal inheritance. In the yellowtail tetra (Astyanax altiparanae) almost all gynogenetic fish were females, suggesting ...
Offspring of male rats exposed to binge alcohol exhibit heightened ethanol intake at infancy and alterations in T-maze performance
(Elsevier Science Inc, 2019-05)
Alcohol use is associated with a variety of negative consequences, including heightened likelihood of cognitive impairment, proclivity to alcohol use disorders (AUD), and alterations in the drinker's offspring. Children ...
The first case of induced gynogenesis in Neotropical fishes using the yellowtail tetra (Astyanax altiparanae) as a model organism
(Elsevier B.V., 2020-01-01)
Gynogenesis is a chromosome manipulation technique applicable on the production of all-female populations, generation of inbred or clonal lines and identification of genetic sex determination mechanisms in fish. Therefore, ...
