Testing the Optimal Foraging Theory in a Generalist Feeder: The Case of Reintroduced European Pond Turtles and Its Impact on Macroinvertebrates Communities

Ecology and Evolution, Volume 15, Issue 8, August 2025.
In this study we investigated the macroinvertebrate (MI) communities in two newly created, man‐made ponds concurrently with the diet of captive‐bred European pond turtles that were translocated there. We aimed at assessing whether turtles were operating as generalist feeders, and if successive reintroductions of turtles would affect the overall MI ...

Responses of a bacterial pathogen to phosphorus limitation of its aquatic invertebrate host [PDF]

, 2008
Host nutrition is thought to affect the establishment, persistence, and severity of pathogenic infections. Nutrient-deficient foods possibly benefit pathogens by constraining host immune function or benefit hosts by limiting parasite growth and ...

Tolerance of organisms composing an Arctic kelp community to ocean warming and marine heatwaves

Journal of Ecology, Volume 113, Issue 8, Page 1938-1954, August 2025.
These results suggest that Arctic kelp communities are fairly tolerant to warming and short‐term marine heatwaves, despite the few minor effects on photosynthesis by some of the kelp species. We note that the future response of kelp communities must account for the potential indirect effects of climate change, such as predation and competition, along ...

Anatomical studies of sibling species within neotropical lymnaeids, snail intermediate hosts of fascioliasis

Memorias do Instituto Oswaldo Cruz, 2006
Several anatomical parameters of the reproductive system have been used to distinguish Lymnaea cubensis from L. viatrix, the snail hosts of fascioliasis in South America and the Caribbean area.

Relative Effects of Eutrophication and Warming on Freshwater Ecosystems Across Ecological Levels

Global Change Biology, Volume 31, Issue 8, August 2025.
This experimental study explores the effects of global change on different ecological levels. We demonstrate that warming primarily impacts lower ecological levels, such as community composition, whereas eutrophication predominantly affects the most integrative ecological level, that is, ecosystem.

Determination of the infection of Lymnaea-gedrosina to trematodes Larval in the water region of Khuzestan

Journal of Fasa University of Medical Sciences, 2011
Background & Objective: The province of Khuzestan with its wide geographical area and its tropical climate is susceptible for the maintenance of snails. One of the prevalent intermediate hosts for trematode in this area is the gasteropode snail, Lymnaea ...

CRISPR/Cas9 Knockout of Shell Matrix Protein 1 in the Slipper‐Snail Crepidula atrasolea

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 5, Page 266-283, July 2025.
Methods for CRISPR/Cas9 shell matrix protein knockout in the snail, Crepidula atrasolea including optimizing RNP delivery and embryo husbandry, to the use of Sanger and MiSeq sequencing, and high‐content screening of embryos to characterize the loss of Shell Matrix Protein 1 (SMP1) during larval shell development.
