The role of refuges in biological invasions: A systematic review

Global Ecology and Biogeography, Volume 32, Issue 8, Page 1244-1271, August 2023., 2023
Abstract Aim Ecological refuges buffer organisms against stressors and mediate a range of species interactions. However, their role in the context of biological invasions has yet to be synthesized, despite the increasing prevalence and impact of non‐native species.

Niche filtering, competition and species turnover in a metacommunity of freshwater molluscs

Oikos, Volume 2022, Issue 9, September 2022., 2022
Metacommunity structure reflects the interplay of various processes, including niche filtering, extinction/colonization and interspecific interactions. Spatial patterns of species distributions are often analyzed to infer these processes. However, such inferences rely on often unrealistic equilibrium assumptions, and remain ambiguous, as different ...

Stable isotope mixing models demonstrate the role of an invasive plant in wetland songbird food webs

Applications in Plant Sciences, Volume 10, Issue 4, July-August 2022., 2022
Abstract Premise Invasive plants in wetlands are often ecosystem engineers, mediating changes in ecosystem functions like trophic support. We documented the impacts of Lepidium latifolium, an invasive plant, on the food web of omnivorous birds (Suisun song sparrows, Melospiza melodia maxillaris) in a tidal wetland of northern California, USA.

The immunobiological interplay between Pseudosuccinea columella resistant/susceptible snails with Fasciola hepatica: Hemocytes in the spotlight [PDF]

Developmental & Comparative Immunology, 2020
The Fasciola hepatica/Pseudosuccinea columella interaction in Cuba involves a unique pattern of phenotypes; while most snails are susceptible, some field populations are naturally resistant to infection and parasites are encapsulated by snail hemocytes. Thus, we investigated the hemocytes of resistant (R) and susceptible (S) P. columella, in particular

The effect of mating on female reproduction across hermaphroditic freshwater snails

Invertebrate Biology, Volume 139, Issue 1, March 2020., 2020
Abstract Sexual conflicts often arise between mating partners because each sex tries to maximize its own reproductive success. One major male strategy to influence a partner's resource allocation is the transfer of accessory gland proteins. This has been shown to occur in simultaneous hermaphrodites as well as in organisms with separate sexes. Although

The Large American Liver Fluke (Fascioloides magna): A Survivor’s Journey through a Constantly Changing World

Parasitologia, 2023
The large American liver fluke (Fascioloides magna) is considered an invasive trematode parasite in Europe. Its origin dates back before the Cretaceous-Paleogene Mass Extinction, after which it survived at least three population bottlenecks and ...

A first report of Pseudosuccinea columella (Say, 1817), an alien intermediate host for fascioliasis, in Malawi

Abstract Starting in October 2021, quarterly malacological surveys have been undertaken in Malawi, sampling 12 specified freshwater habitats throughout a calendar year. Each survey monitors the presence of aquatic intermediate snail hosts of medical and veterinary importance; in March 2023, the alien lymnaeid species Pseudosuccinea columella ...

Susceptibilidade de Lymnaea (pseudosuccinea) columella (Say, 1817) exposta à infecção por miracídios de Fasciola hepatica (Linnaeus, 1758)

Revista do Instituto de Medicina Tropical de São Paulo, 1988
Com o objetivo de estudar a susceptibilidade de Lymnaea (pseudosuccinea) columella de Minas Gerais, Estado onde ainda não se registraram casos autóctones de fasciolose hepática, foram utilizadas as amostras MG 1, MG 2, MG 3 e MG 4, provenientes de ...

Variation of snail's abundance in two water bodies harboring strains of Pseudosuccinea columella resistant and susceptible to Fasciola hepatica miracidial infection, in Pinar del Río Province, Cuba

Memorias do Instituto Oswaldo Cruz, 2005
The abundance of freshwater snails in two rural sites of Pinar del Río, Cuba, which harbor Pseudosuccinea columella susceptible and resistant to miracidia of Fasciola hepatica was followed for one year. Susceptible snails were found in the most anthropic
