Classification of Planorbidae cellected from Geum river basin
The Korean Journal of Parasitology, 1983 The distribution, external morphology, radula, chromosome numbers of Planorbidae snails were studied. 1. The specimens were collected at four stations in Nonsangun, Kongjugun, and Daedukgun which are located around Geum river. Three genera and three species of Planorbidae, Hippeutis cantori, Segmentina hemisphaerula and Gyraulus convexiusculus, were ...

Revista do Instituto de Medicina Tropical de São Paulo, 1992 Studies on eight localities on the Island of Santa Catarina revealed the presence of three species of the molluscan family Planorbidae: Biomphalaria tenagophila, Drepanotrema cimex and Biomphalaria oligoza, the first one being naturally infected by ...

Oikos, Volume 2025, Issue 7, July 2025.Parasite occurrence and infection estimates vary through time and space, making understanding the underlying drivers highly complex. Comparative studies based on empirical data must consider the factors of variation involved in estimating infection metrics in natural populations to make appropriate and reliable comparisons. Using a multi‐scale approach,

Unexpected Shifts in Bivalve Function From Filtration to Transmission Risk
Freshwater Biology, Volume 70, Issue 6, June 2025.ABSTRACT Understanding the complex interactions between filter‐feeding species and zoonotic disease transmission in aquatic environments is crucial for accurately quantifying the ecosystem services provided by these organisms. This study explores for the first time the roles of freshwater bivalves in the transmission dynamics of emerging zoonotic ...

Revealing hidden sources of uncertainty in biodiversity trend assessments
Ecography, Volume 2025, Issue 5, May 2025.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
Freshwater Biology, Volume 70, Issue 3, March 2025.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 ...

When One Global Invasion Hides Another—Cryptic Interspecific Invasion in Freshwater Gastropods
Diversity and Distributions, Volume 31, Issue 1, January 2025.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
Limnology and Oceanography Letters, Volume 9, Issue 6, Page 696-715, December 2024.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
