Phylogeography and genetics of the globally invasive snail Physa acuta Draparnaud 1805, and its potential to serve as an intermediate host to larval digenetic trematodes

BMC Evolutionary Biology, 2018
Background Physa acuta is a globally invasive freshwater snail native to North America. Prior studies have led to conflicting views of how P. acuta populations are connected and genetic diversity is partitioned globally.

Matching maternal and paternal experiences underpin molecular thermal acclimation

Molecular 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.

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

Larvae of the water scavenger beetle, Hydrophilus acuminatus (Coleoptera: Hydrophilidae) are specialist predators of snails

European Journal of Entomology, 2015
Hydrophilus acuminatus larvae are known to feed on aquatic prey. However, there is no quantitative study of their feeding habits. In order to determine the feeding preferences and essential prey of larvae of H.

Environmental DNA Particle Size Distribution and Quantity Differ Across Taxa and Organelles

Environmental DNA, Volume 6, Issue 5, September–October 2024.
ABSTRACT The use of environmental DNA to detect species is now widespread in freshwater ecology. However, the detectability of species depends on many factors, such as the quantity of eDNA particles available in the environment and their state (e.g., free DNA fragments, organellar, or aggregated DNA particles).

Ovoposició en poblacions de "Physa acuta" "(Gastropoda: Pulmonata)" mantingudes al laboratori [PDF]

, 2005
The ovipositional parameter, number of egg masses/snailxday, has been recorded in laboratory-kept populations of Physa acuta in the period 1973-1975. The results show a clear non circadian rhythm with a period slightly over 3 days long, and whose extent ...

Invasive freshwater snails are less sensitive to population density than native conspecifics

Ecology and Evolution, Volume 14, Issue 5, May 2024.
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 ...

Temperature drives asymmetric competition between alien and indigenous freshwater snails (Physa acuta vs. Physa fontinalis)

, 2015
Biological invasion represent one of the major threats to global biodiversity as alien species often displace indigenous species. However, knowledge of the mechanisms behind such displacements and the driving factors of the competitive superiority of the
