The Architecture of the Physid Musculature ofPhysa acutaDraparnaud, 1805 (Gastropoda: Physidae) [PDF]

open access: yesAfrican Invertebrates, 2009
ABSTRACT The basommatophoran family Physidae possesses a remarkable but little known set of muscles called the “physid musculature”. Using Physa acuta as a model, this musculature was shown to be anatomically complex and associated in places with the columellar muscle.

Genome Architecture and Speciation in Plants and Animals

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.

Matching maternal and paternal experiences underpin molecular thermal acclimation

open access: yesMolecular Ecology, Volume 34, Issue 15, August 2025.
Abstract The environment experienced by one generation has the potential to affect the subsequent one through non‐genetic inheritance of parental effects. Since both mothers and fathers can influence their offspring, questions arise regarding how the maternal, paternal and offspring experiences integrate into the resulting phenotype.

NO CORRELATION BETWEEN INBREEDING DEPRESSION AND DELAYED SELFING IN THE FRESHWATER SNAIL PHYSA ACUTA [PDF]

open access: yesEvolution, 2007
Inbreeding depression, one of the main factors driving mating system evolution, can itself evolve as a function of the mating system (the genetic purging hypothesis). Classical models of coevolution between mating system and inbreeding depression predict negative associations between inbreeding depression and selfing rate, but more recent approaches ...
