Experimental evidence of inbreeding avoidance in the hermaphroditic snail Physa acuta [PDF]
Evolutionary Ecology, 2018 Inbreeding depression should select for inbreeding avoidance behaviours. Here we test this hypothesis in two populations of the simultaneous hermaphroditic freshwater snail Physa acuta.

Effect of mating history on gender preference in the hermaphroditic snail Physa acuta [PDF]
Animal Behaviour, 2007 Several internally fertilizing hermaphroditic animals can only perform one sexual role at a time. In such species, two individuals that engage in a copulation may have different interests in acting as male or female. A gender choice must be made which, if both individuals have the same preference, may give rise to a severe sexual conflict.

Physa acuta Draparnaud, 1805 (Gastropoda: Physidae): a study of topotypic specimens [PDF]
Memórias do Instituto Oswaldo Cruz, 2003 A description is given of Physa acuta Draparnaud, 1805, based on topotypic specimens from the Garonne river basin, and additional samples from the environs of the French cities of Montpellier and Perpignan. It proved indistinguishable, in shell and anatomy, from topotypic Physa cubensis Pfeiffer, 1839, thus leading the authors to admit the synonymy of ...

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

Ecosphere, Volume 14, Issue 12, December 2023., 2023 Abstract Riffles are heterogeneous habitats that support diverse assemblages in natural streams. They are often constructed as part of stream restoration practice, including in degraded urban stream ecosystems, despite larger scale limits to ecological state.

American Journal of Botany, Volume 110, Issue 10, October 2023., 2023 Abstract Premise What maintains mixed mating is an evolutionary enigma. Cleistogamy—the production of both potentially outcrossing chasmogamous and obligately selfing cleistogamous flowers on the same individual plant—is an excellent system to study the costs of selfing.

Thirty years of slug control using the parasitic nematode Phasmarhabditis hermaphrodita and beyond
Pest Management Science, Volume 79, Issue 10, Page 3408-3424, October 2023., 2023 The nematode Phasmarhabditis hermaphrodita is a parasite of slugs and snails and has been formulated into a biological control agent for use across northern Europe since 1994. Here, we review all research on P. hermaphrodita that has been carried out over the last 30 years and suggest future priorities.

Journal of the World Aquaculture Society, Volume 54, Issue 5, Page 1247-1259, October 2023., 2023 Abstract Bolbophorus damnificus is a digenetic trematode causing significant economic losses within the United States commercial catfish industry. The indirect life cycle is complex, requiring piscivorous birds, aquatic snails, and fish to complete.

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023 In response to uncertain risks, prey may rely on neophobic phenotypes to reduce the costs associated with the lack of information regarding local conditions. We conducted an in situ field experiment of two high‐risk guppy populations designed to determine how the ‘average’ and ‘variance’ of several environmental factors might influence the neophobic ...
