Going with the flow? Diversification of gastropods reflects drainage evolution in Africa

Journal of Biogeography, Volume 48, Issue 7, Page 1579-1593, July 2021., 2021
Abstract Aim The roles of geodynamics, climatic variability and landscape evolution in shaping aquatic biodiversity patterns on the African continent remain poorly understood. We studied the geographical origin and phylogenetic relationships of an Afrotropical freshwater snail genus to examine the role of drainage evolution on diversification and range

A Dissenters’ View on AppleSnail Immunobiology

Frontiers in Immunology, 2022
We stand as dissenters against the acceptance of scientific knowledge that has not been built on empirical data. With this in mind, this review synthesizes selected aspects of the immunobiology of gastropods and of apple snails (Ampullariidae) in ...

A new species of Pila (Gastropoda: Ampullariidae) from Mizoram, India

Molluscan Research, 2021
Family Ampullariidae consists of 11 genera of freshwater snails distributed pan-tropically in the Old and the New World. One of the ampullarid genera, Pila, is distributed in Africa and Asia and consists of 28 species. Here we describe the sixth member of the genus Pila from India. Pila mizoramensis n. sp.

A multiple comparative study of putative endosymbionts in three coexisting apple snail species [PDF]

PeerJ, 2019
We here compare morphological and molecular characters of some putative endosymbiotic elements of the digestive gland of three ampullariid species (Pomacea canaliculata, Pomacea scalaris and Asolene platae) which coexist in Lake Regatas (Palermo, Buenos ...

Morphometric study of a Brazilian strain of Carchesium polypinum (Ciliophora: Peritrichia) attached to Pomacea figulina (Mollusca: Gastropoda), with notes on a high infestation

Zoologia (Curitiba), 2010
During an ecological study of the epibiotic relationship between ciliate protists and Pomacea figulina (Spix, 1827) (Gastropoda, Ampullariidae), originating from an urban stream in southeast Brazil, a high infestation by the peritrich ciliate Carchesium ...

Survivorship of geographic Pomacea canaliculata populations in responses to cold acclimation

Ecology and Evolution, Volume 10, Issue 8, Page 3715-3726, April 2020., 2020
Survival of Pomacea canaliculata depends on their shell height and the level of low temperature. P. canaliculata population from the mid‐subtropical zone exhibit the highest viability over the cold thermal range. Abstract Pomacea canaliculata, a freshwater snail from South America, has rapidly established natural populations from south to north ...

Nuptial Feeding In the Freshwater Snail Pomacea canaliculata (Gastropoda: Ampullariidae)

Malacologia, 2007
The males of the freshwater snail Pomacea canaliculata have a copulatory apparatus consisting in a delicate penis running through a muscular channeled sheath bearing three different glands. The outer gland is the most conspicuous one and often secrets a sticky drop of mucus during copula.

First record of epibionts peritrichids and suctorians (Protozoa, Ciliophora) on Pomacea lineata (Spix, 1827)

Brazilian Archives of Biology and Technology, 2006
This study made a survey on the ciliate protozoans from Peritrichid and Suctorian taxa, epibionts of Pomacea lineata (Spix, 1827) (Ampullariidae). Fifty mollusks were collected in places of irrigation ditches and shell was scraped with a scalpel and the ...

Assessment of the kidney and lung as immune barriers and hematopoietic sites in the invasive apple snail Pomacea canaliculata [PDF]

PeerJ, 2018
Knowledge on the immune system of Pomacea canaliculata is becoming increasingly important, because of this gastropod’s role as intermediate host and vector of Angiostrongylus cantonensis, the etiologic agent of eosinophilic meningitis in humans and ...
