Reproductive and development biology
Reproduction and early developmental stages determine the offspring and survival of living organisms. Marine invertebrate reproduction is particularly interesting due to its great diversity as well as the multiple habitats and environmental conditions in which it occurs, leading to a broad variety of reproductive modalities. Marine invertebrates exhibit complex life cycles that may include: external or internal fertilization, development through lecitotrophic or planctotrophic larvae, and even species with direct development (within egg capsules) as well as parental care and incubation.
Strong components of the studies we carry out at LARBIM are focused on reproduction and development of marine invertebrates. The main taxonomic groups we currently study are molluscs, echinoderms and nemerteans. Our studies cover behavioural features such as mating and egg laying, embryonic and larval development, fecundity, nutrition modalities of embryonic stages, parental care, seasonality and reproductive maturity (gametogenic and behavioural). We also study the relationship between reproductive features of marine invertebrates and environmental parameters (physical, chemical and biological), in a variety of extreme and diverse habitats such as intertidal and shallow subtidal Patagonian shores, abyssal depths and subantarctic waters.
The study of reproduction and development of marine invertebrates and their relationship with other features within benthic ecosystems is particularly interesting for the integrative approach we promote at LARBIM.
