The Solitary Islands Marine Park is positioned in a transition zone between tropical and temperate regions and consequently supports a range of taxa with different biogeographic affinities. Driven by variable influence of the East Australian Current, there is increasing representation of tropical taxa along a cross-shelf gradient (inshore to offshore). Patterns in the population of the endolith...

In the present study, two small lakes on the margins of the River Cuiabá were analyzed regarding taxonomic composition and population densities of the zooplankton. Diversity was evaluated for two groups, Rotifera and Cladocera; sampling was carried out on two dates: 2 March 1999, in the rainy season, and 25 August 1999, in the dry season. Seventy-nine rotifer taxa, 30 cladoceran taxa, and 6 cop...

Cipangopaludina cathayensis (Gastropoda: Prosobranchia; Mesogastropoda; Viviparidae) is widely distributed in the freshwater habitats of China. It an economically important snail with high edible and medicinal value. However, genomic resources reference genome this are lacking. In study, we assembled first chromosome-level C. cathayensis. The preliminary assembly was 1.48 Gb size, a contig N50 ...

This study aimed to develop original laboratory culture and sediment toxicity testing protocols for the freshwater gastropod Bellamya aeruginosa (Reeve), a new potential species for sediment toxicity testing. B. aeruginosa was successfully cultured with an effective culture system under proposed laboratory conditions. Optimal ad libitum feeding levels for larvae, juveniles, and adults were 2.0,...
