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

open access: yesEcology 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

open access: yesEcology 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.

Stay in shape: Assessing the adaptive potential of shell morphology and its sensitivity to temperature in the invasive New Zealand mud snail Potamopyrgus antipodarum through phenotypic plasticity and natural selection in Europe

open access: yesEcology and Evolution, Volume 12, Issue 10, October 2022., 2022
In invasive populations of the New Zealand Mud Snail in Europe shell morphology, which is fitness relevant, is sensitive to temperature. The genetic variation underlying size and shape is very limited. As temperature is obviously not the sole factor influencing shell morphology, their interaction will probably not be a factor limiting population ...

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

open access: yes, 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

Differences on allocation of available resources, in growth, reproduction, and survival, in an exotic gastropod of Physidae compared to an endemic one Diferencias en la asignación de los recursos disponibles en crecimiento, reproducción y supervivencia entre un gasterópodo exótico y uno endémico de la familia Physidae

open access: yesIheringia: Série Zoologia, 2010
Physa acuta Draparnaud, 1805 is an invasive gastropod that can affect local species. In Argentina, it is widespread and abundant, even in environments inhabited by the native species Stenophysa marmorata Guilding, 1828.
