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

Invasive freshwater gastropods in South America: Physa acuta and its expansion to Austral Patagonia in Argentina

Papéis Avulsos de Zoologia
Physa acuta is a freshwater snail of North American origin that has spread to all continents. In South America it was detected for the first time in 1966 (Brazil) and is currently present in Argentina, Brazil, Peru, Chile, Colombia, Ecuador and Uruguay ...

Biochemical responses to the toxicity of the biocide abamectin on the freshwater snail Physa acuta

Ecotoxicology and Environmental Safety, 2014
The toxic effects of abamectin (ABM), an anthelmintic drug, on the snail, Physa Acuta, and the biochemical responses to the exposure stress were evaluated. The activities of superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), acetylcholinesterase (AChE), and nitric oxide synthase (NOS), and the contents of malondialdehyde (MDA)

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).

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 ...

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.

Food web structures of irrigated rice fields estimated from carbon and nitrogen stable isotopes: Special reference to the role of filamentous green algae as a food resource of aquatic consumers

Ecological Research, Volume 39, Issue 3, Page 318-329, May 2024.
We examined aquatic food web structures in two adjacent rice fields in northeastern Japan using carbon and nitrogen stable isotope ratios. δ13C‐based isotopic mixing model estimated that the majority of herbivores and omnivores, as well as several carnivorous taxa, assimilated carbon derived from filamentous green algae (contributions to carbon ...

Fitness effects of assisted gene flow in an endangered salmonid population

Conservation Science and Practice, Volume 6, Issue 1, January 2024.
This study investigates the impact of assisted gene flow on the fitness of an endangered landlocked salmon population. Our results reveal that while assisted gene flow can have a positive influence on individual growth, it can also lead to decreased survival rates under predation risk.
