The threat of native molluscs by the New Zealand mud – snail (Potamopyrgus antipodarum (gray) = Угроза для местных моллюсков со стороны новозеландского слизня [PDF]

open access: yes, 2002
Potamopyrgus antipodarum has been introduced to brackish and fresh waters of Europe probably in the first half of XIXth century, when the regular clipper lines have connected from 1840 the British Isles with New Zealand.

Identifying invertebrate invasions using morphological and molecular analyses: North American Daphnia ‘pulex’ in New Zealand fresh waters [PDF]

open access: yes, 2012
We used a DNA barcoding approach to identify specimens of the Daphnia pulex complex occurring in New Zealand lakes, documenting the establishment of non-indigenous North American Daphnia 'pulex'.

Glabralysins, potential New β-pore-forming toxin family members from the schistosomiasis vector snail biomphalaria glabrata [PDF]

open access: yes, 2020
Biomphalaria glabrata is a freshwater Planorbidae snail. In its environment, this mollusk faces numerous microorganisms or pathogens, and has developed sophisticated innate immune mechanisms to survive.

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Cercarial fauna of freshwater snails in selected agricultural areas in Laguna, Philippines

open access: yesHelminthologia, 2019
Freshwater snails serve as one of trematodes’ intermediate hosts. Previous studies on trematode larval stages in the Philippines have largely focused on species with public health importance.

De Novo transcriptome analysis of Oncomelania hupensis after molluscicide treatment by next-generation sequencing: implications for biology and future snail interventions. [PDF]

open access: yesPLoS ONE, 2015
The freshwater snail Oncomelania hupensis is the only intermediate host of Schistosoma japonicum, which causes schistosomiasis. This disease is endemic in the Far East, especially in mainland China.

Gastropod communities of the reservoirs and the rivers of the Ciechanowska Upland = Сообщества Gastropodа в водохранилишах и реках Цехановского Нагорья [PDF]

open access: yes, 2002
The aims of research were: analysis of the number of species, density, domination, constancy and commonness of the gastropod communities in the water environments of the Ciechanowska Upland (northeastern part of Po-land), analysis of biodiversity of the ...

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

Snails promote methane release from a freshwater lake ecosystem

open access: yesFrontiers in Environmental Science, 2014
Benthic fauna, as ecosystem engineers, can strongly affect microbial-driven ecosystem biogeochemical cycling. However, the effects of benthic fauna, especially epifauna, on CH4 cycling remain still elusive.

Tolerance to air exposure of the New Zealand mudsnail Potamopyrgus antipodarum (Hydrobiidae, Mollusca) as a prerequisite to survival in overland translocations [PDF]

open access: yes, 2013
Spreading throughout a new ecosystem is the last step of an exotic species to become invasive. In the case of invasive aquatic molluscs, tolerance to air exposure is one of the main mechanisms allowing overland translocation and spreading.
