    Thick-billed Murres in breeding pairs migrate and overwinter far apart but in similar photic environments

    Scheduling between mates in species with long-term pair bonds can be essential for positive fitness. The annual cycle in photoperiod is the primary environmental cue used by many animals to synchronize behavio...

    Marine invertebrate epibionts on photophilic seaweeds: importance of algal architecture

    The macrofauna of marine invertebrates of two photophilic algal communities on the Maresme coast (Barcelona, NE Spain) were studied. We evaluated how the type of algal substrate (soft or hard thallus algae) af...

    Stargazing under the sea: molecular and morphological data reveal a constellation of species in the Berthella stellata (Risso, 1826) species complex (Mollusca, Heterobranchia, Pleurobranchidae)

    Molecular and morphological evidence support the view that the widely distributed species Berthella stellata (Risso, 1826) is a species complex of at least eight different species. The closely related species Ber...
