We present a genome assembly from an individual Anisus vortex (the Whirlpool Ramshorn snail; Mollusca; Gastropoda; Hygrophila; Lymnaeoidea; Planorbidae). The genome sequence is 869.5 megabases in span.

Revealing hidden sources of uncertainty in biodiversity trend assessments
Idiosyncratic decisions during the biodiversity trend assessment process may limit reproducibility, whilst ‘hidden' uncertainty due to collection bias, taxonomic incompleteness, and variable taxonomic resolution may limit the reliability of reported trends.

Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components
ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...

The South-American distribution and southernmost record of Biomphalaria peregrina—a potential intermediate host of schistosomiasis [PDF]
Schistosomiasis remains a major parasitic disease, endemic in large parts of South America. Five neotropical species of Biomphalaria have been found to act as intermediate hosts of Schistosoma mansoni in natural populations, while others have been shown ...

When One Global Invasion Hides Another—Cryptic Interspecific Invasion in Freshwater Gastropods
ABSTRACT Aim Cryptic invasions are an understudied phenomenon among species invasions, especially in freshwater invertebrates. We study the gastropod family Physidae, including the global invaders Physella acuta and several enigmatic Stenophysa species, their phylogenetic relationships and the presence of native species among African Physidae. We infer

A dataset of individual wet weights of benthic macroinvertebrates
Abstract Biomass estimates are crucial for modeling and understanding energy flow through ecosystems. Many modeling frameworks rely on published body weights of organisms to convert density estimates to biomass. However, published body weight data are limited to few taxa in a limited number of systems. Here we present mean individual weights for common

True metabolizable energy of foods consumed by lesser scaup (Aythya affinis)
Estimating true metabolizable energy (TME) of available foods has become a common way for resource managers to increase reliability in energetic carrying capacity estimates and precision of management actions. We estimated nitrogen adjusted TME of five common foods of lesser scaup (Aythya affinis) by conducting feeding trials with wild birds.
