Size-assortative mating in simultaneous hermaphrodites: an experimental test and a meta-analysis [PDF]

, 2015
Assortative mating by size has been argued to be widespread in the animal kingdom. However, the strength of size-assortative mating is known to vary considerably between species and the underlying mechanisms promoting this inter-specific variation remain

Life history and population ecology of Radix swinhoei (Lymnaeidae) in nearshore regions of a hypereutrophic plateau lake

Ecology and Evolution, Volume 12, Issue 12, December 2022., 2022
The life history traits (life span and growth), annual secondary production, and population size structure of Asia widespread pulmonate Radix swinhoei were carefully and systematically examined across 1 year in nearshore regions of a hypereutrophic plateau lake, Lake Dianchi. The maximum potential life span of R.

Diet quality impairs male and female reproductive performance and affects the opportunity for selection in an insect model

Ecology and Evolution, Volume 12, Issue 11, November 2022., 2022
Environmental factors can have profound effects on the strength and direction of selection and recent studies suggest that such environmentdependent selection can be sex‐specific. We manipulated diet quality in an insect model finding no sex‐specific effect of dietary stress on reproductive success.

Invasive freshwater snails are less sensitive to population density than native conspecifics. [PDF]

Ecol Evol
Species invasion can negatively affect natural ecosystems, so understanding how and why lineages become invasive is critically important to effectively predict potential future invasions. We address whether key life‐history traits across invasive versus native lineages of a New Zealand freshwater snail species differ in response to population density ...

Diverzita vodních měkkýšů řeky Turiec (Slovensko) [PDF]

Malacologica Bohemoslovaca, 2023
During a detailed faunistic survey of the river Turiec in northern Slovakia in 2013–2022, we found 18 species of aquatic molluscs (8 gastropods and 10 bivalves) at 9 sites. The most species-rich assemblages were in the middle course of this river.

First report of Chaetogaster limnaei (Annelida: Naididae) in Chile based on samples retrieved from an invasive freshwater snail

Revista Mexicana de Biodiversidad, 2019
Some naidid oligochaetes establish commensal relationships with species of molluscs worldwide. In the present study, we report the finding of Chaetogaster limnaei in Illapel River, northern Chile.
