Abstract Loma acerinae is a xenoma-forming fish microsporidium described from common ruffe Gymnocephalus cernua (Perciformes: Percidae) and also found in Ponto-Caspian gobies (Gobiiformes: Gobiidae). This casts doubt on the strict host specificity of this parasite. The largest subunit RNA polymerase II ( rpb1 ) was used as genetic marker parasite isolated six species Perciformes G.

The study of assemblages fish in their early phases estuaries is an essential approach to understanding the functioning these types ecosystems and role as nursery grounds for some marine species. main aim this was analyze ichthyoplankton assemblage Bons Sinais Estuary, specifically clarify use area by species socio-economic interest. This identified 22 larval taxa among families, genera, Gobiid...

Tropical deep reefs (~40–300 m) are diverse ecosystems that serve as habitats for communities of reef-associated fishes. Deep-reef fish taxonomically and ecologically distinct from those on shallow reefs, but like they home to a species-rich assemblage small, cryptobenthic reef fishes, including many species the family Gobiidae (gobies). Here we describe two new deep-reef gobies, Varicus promet...

Why non-breeding subordinates of many animal societies tolerate group-living remains a pertinent question in evolutionary biology. The ecological constraints and benefits of philopatry hypotheses have the potential to explain the maintenance of group-living by specifying the ecological conditions favouring delayed dispersal over independent breeding by subordinates. In this study, I used field ...
