Associations Between Two Trematode Parasites, an Ectosymbiotic Annelid, and Thiara (Tarebia) Granifera (Gastropoda) in Jamaica

Journal of Parasitology, 2011
This work describes associations of Thiara (Tarebia) granifera, its larval trematode community, and Chaetogaster limnaei limnaei at a freshwater reservoir in Jamaica. Larvae of 2 trematodes were present, i.e., a notocotylid (15.3%) and Philophthalmus sp. (1.3%), in 3,575 T. granifera examined.

Fine Structure of Spermatogenesis in the Snail Tarebia Granifera (Melaniidae)

Proceedings, annual meeting, Electron Microscopy Society of America, 1977
Jacob (1), citing chromosomal studies, emphasized the extreme rarity, or possible non-existence of viable males in observed Indian populations of Melanoides tuberculatus, of the same family as Tarebia granifera. The snail population, almost totally female in chromosomal count, were presumed to reproduce parthenogenetically; no sexual reproduction was ...

Evaluating the ecological consequences of Tarebia granifera density on benthic diatom communities in South African river systems

open access: yesBiological Invasions
Abstract Invasive species pose a significant threat to global freshwater biodiversity. The invasive snail Tarebia granifera has been reported to exploit microphytobenthos and detritus, potentially exercising a greater feeding impact compared to other invertebrates. Despite its presence in several important conservation regions in the country,

Fine Structure of Oogenesis in the Snail Tarebia Granifera (Melaniidae)

Proceedings, annual meeting, Electron Microscopy Society of America, 1977
The ovary of the fresh-water snail, Tarebia granifera, is found in the caudal upper whorls of the shell. Careful dissection was required to separate the ovary from the digestive gland which shared a common epithelial covering with the ovary. The ovarian tissue was fixed in sodium cacodylate buffered 3% glutaraldehyde, post-fixed in 1% osmium tetroxide,

First record of an intermediate thiarid snail host; Tarebia granifera (Lamarck, 1822) of the lung trematod (Paragonomus westermani Kerbert) in Qena Province, Upper Egypt [PDF]

open access: yesEgyptian Journal of Aquatic Biology and Fisheries, 2021
In a one-year study, a new record of the freshwater thiarid snail, Tarebia granifera, was collected in huge amounts from the River Nile in Qena province, Upper Egypt. Tarebia granifera is a highly invasive species that has spread throughout the tropical world and can displace native gastropods as well as cause damage to water systems by clogging pipes ...

The abundance of an invasive freshwater snail Tarebia granifera (Lamarck, 1822) in the Nseleni River, South Africa

African Journal of Aquatic Science, 2017
The invasive freshwater snail Tarebia granifera (Lamarck, 1822) was first reported in South Africa in 1999 and it has become widespread across the country, with some evidence to suggest that it reduces benthic macroinvertebrate biodiversity. The current study aimed to identify the primary abiotic drivers behind abundance patterns of T.
