Prevalence and intensity of Angiostrongylus cantonensis in freshwater snails in relation to some ecological and biological factors

Parasite, 2007
The purpose of the study was to record different intermediate hosts of A. cantonensis and to determine the infection prevalence and intensity of this parasite in freshwater snails in relation to some ecological and biological factors.

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Putting Structural Variants Into Practice: The Role of Chromosomal Inversions in the Management of Marine Environments

Molecular Ecology, EarlyView.
ABSTRACT Major threats to marine species and ecosystems include overfishing, invasive species, pollution and climate change. The changing climate not only imposes direct threats through the impacts of severe marine heatwaves, cyclones and ocean acidification but also complicates fisheries and invasive species management by driving species range shifts.

Gastropods potential intermediate hosts of parasites in the region of Lençóis Maranhenses National Park/Brazil, an international tourist destination [PDF]

Brazilian Journal of Biology
Several aquatic ecosystems present favorable conditions for the establishment of freshwater gastropod populations in Maranhão (Brazil). However, research on these snails in this Brazilian state is more focused on Baixada Maranhense, an endemic area for ...

Genome Architecture and Speciation in Plants and Animals

Molecular Ecology, EarlyView.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.

Ecological and Mutation‐Order Speciation in Senecio

Molecular Ecology, EarlyView.
ABSTRACT Natural selection shapes how new species arise, yet the mechanisms that generate reproductive barriers remain actively debated. Although ecological divergence in contrasting environments and mutation‐order processes in similar environments are often viewed as distinct speciation mechanisms, we show they can occur simultaneously and act as part

Overlooked and underestimated: reframing restoration to include inconspicuous native invaders

Restoration Ecology, EarlyView.
Anthropogenic changes cause some native species to increase in abundance or distribution. These hyperabundant natives, native invaders, follow the same ecological ‘rules’ as exotic invasives and can have comparable impacts. However, their management is a relatively new challenge in restoration ecology, with most frameworks operating within a native ...

Structural and Functional Variations of Enzymes Indicate Latitudinal Adaptations of Subarctic and Arctic Sea Urchins

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Rapid warming in Arctic fjords challenges cold‐adapted benthic species, such as sea urchins of the genus Strongylocentrotus, key grazers on kelp forests. By comparing Arctic and Subarctic populations, we identified genetic and enzymatic differences in Arctic sea urchins, suggesting enhanced metabolic efficiency at low temperatures and potential for ...

Composition and Distribution of Snail Fauna in Water Bodies around Irrigation Schemes of Benue River Valley, Yola Area, Adamawa State, Nigeria

Journal of Applied Sciences and Environmental Management
Freshwater snails that act as intermediate host and some abiotic environmental factors plays a prominent roles in these infections. The objective of this paper as to assess the composition and distribution of the snail fauna in water bodies around ...

A survey of freshwater and terrestrial snails in a predominantly urban municipality of Rio de Janeiro State, Brazil, with emphasis on human parasites vectors

Revista do Instituto de Medicina Tropical de São Paulo, 2018
Many snail species act as intermediate hosts of helminths that transmit diseases to humans and animals, such as schistosomiasis and angiostrongyliasis.
