There are known plenty tiny invertebrate species associated with decapod crustaceans. Our contribution documents the first record of New Guinean ornamental Cherax crayfish epibiont, Diceratocephala boschmai (Platyhelminthes: Temnocephalida) found in pet trade Czech Republic. Correct assignment was confirmed by genetic barcoding. The pathway for introductions organisms unintentionally moved asso...

Abstract Antarctic krill ( Euphausia superba ) are amongst the most abundant animals on Earth, with a circumpolar distribution in Southern Ocean. Genetic and genomic studies have failed to detect any population structure for species, suggesting single panmictic population. However, hyper‐abundance of slows rate genetic differentiation, masking potential underlying structure. Here we use high‐th...

BACKGROUND Diseases associated to external parasitosis are scarcely reported in sea turtles. During the last decades several organism have been documented as a part of normal epibiont community connected to sea turtles. The copepod Balaenophilus manatorum has been cited as a part of epibiont fauna with some concern about its parasitic capacity. This study serves three purposes, i.e. (i) it shed...

In this paper, we describe the first association of ostreid species Ostrea puelchana d’Orbigny, 1842, as new epibiont in Eriphia gonagra (Fabricius, 1781), with material collected Northeastern Brazil. The specimens E. were manually November 2020 during low tide Barra de Catuama beach, State Pernambuco. Among 10 collected, only one adult male showed presence two commensal O. adhered epibranchial...

Dinoroseobacter shibae DFL 12T is a metabolically versatile member of the world-wide abundant Roseobacter clade. As an epibiont of dinoflagellates D. shibae is subjected to rigorous changes in oxygen availability. It has been shown that it loses up to 90% of its intracellular ATP when exposed to anoxic conditions. Yet, D. shibae regenerates its ATP level quickly when oxygen becomes available ag...

Invasive species can alter coastal ecosystems both directly, e.g. through competition for substratum and nutrients, and indirectly. Indirect effects may be mediated by creation of dissimilar or inimical habitats, changes in predator and/or prey assemblages, alterations in associated biota, and perturbations of water movement and thermal regimes. Previous studies have shown that invasive algae c...
