We describe a new species of Stenasellus Dollfus, 1897 (Isopoda: Asellota: Stenasellidae) from stagnant freshwater habitats in a cave on Socotra Island, Yemen. S. taitii n.

Environmental risk assessment of propranolol in the groundwater bodies of Europe.

A growing concern for contamination due to pharmaceutical compounds in groundwater is expanding globally. The β-blocker propranolol is a β-adrenoceptors antagonist commonly detected in European groundwater bodies. The effect of propranolol on stygobiotic species (obligate groundwater dweller species) is compelling in the framework of environmental risk assessment (ERA) of groundwater ecosystems.

Characterization of polymorphic microsatellite loci in the marine isopod Sphaeroma terebrans (Crustacea, Isopoda).

Nine polymorphic microsatellites were characterized in the marine isopod Sphaeroma terebrans (Isopoda, Sphaeromatidae) for phylogeographic and parentage analyses. The number of alleles ranged from 3 to 10. Observed heterozygosity ranged from 0.
