Brood care in Brachyuran crabs: the effect of oxygen provision on reproductive costs
Provedor de dados: 97
Autores: FERNÁNDEZ,MIRIAM; BRANTE,ANTONIO.
The quantification of the costs associated with parental care of marine invertebrates requires a first and necessary step, which is the identification of the different forms of care exhibited by this group. Among marine invertebrates, provision of oxygen to the aggregation of embryos may be critical, although most evidence on the link between oxygen limitation and parental care is indirect. Species which show active behavior directed at providing oxygen to the brood offer a good model to establish the direct link between behavioural patterns and oxygen provision to the embryos, and to estimate the costs associated with this form of care. In this manuscript, we conducted a review of the current knowledge about oxygen limitation in embryos aggregations of...

Latitudinal comparisons of reproductive traits in five Brachyuran species along the Chilean coast

Understanding large-scale patterns in reproductive investment and fecundity of marine invertebrates is important for determining the critical environmental variables affecting reproduction and thus, the spatial patterns of population dynamics. However, information on patterns of reproduction of marine invertebrates at large spatial scales are either scarce, or have been conducted by mixing species with contrasting modes of development. Brachyuran crabs are an ideal group to analyze large-scale patterns of reproduction not only because many species are commercially exploited, but also because they show a single mode of larval development and wide distributional ranges. Here, we report latitudinal patterns of reproductive variables in five Brachyuran crab...
