TL;DR: Salinity tolerance experiments in the laboratory showed that all individuals in the seawater control survived while 25% survived a 12-hour exposure to freshwater from Gatun Lake, confirming that some A. peruviana individuals can survive even the estimated maximum transit of up to 12 hours through the Panama Canal.

TL;DR: It is shown that shell sculpture is habitat-dependent and indeed evolved several times independently in lentic River Snails, and that directional evolution towards smooth shells in lotic habitats explains why sculptured shells are rarely found in these habitats.

TL;DR: Sperm packages of 11 paludomid cerithioideans from Lake Tanganyika suggest that the spermatophore-forming organ is a synapomorphy of Paludomidae, that a bifurcate sperMatophore structure is plesiomorphic, and that the evolution of structurally complex, spiny sPermatophores has occurred independently in disparate lineages within the thalassoid species flock.

TL;DR: The present analysis confirms that syrnolopsines possess a spermatophore-forming organ – a synapomorphy of the Paludomidae – corroborating their placement in this family.

TL;DR: It is argued that a multi-marker approach combined with taxonomic expertise to develop a curated, vouchered, local barcode database increases taxon detection with metabarcoding, and its potential as a tool for zooplankton biodiversity surveys is argued.
