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.

Feeding dynamics of the invasive gastropod Tarebia granifera in coastal and estuarine lakes of northern KwaZulu-Natal, South Africa

Estuarine, Coastal and Shelf Science, 2011
Abstract Gut fluorescence and carbon budget techniques were applied to Tarebia granifera (shell height 10–12 mm) at the iSimangaliso Wetland Park, a UNESCO World Heritage Site. This snail has recently invaded a number of estuaries in northern KwaZulu-Natal, where it reaches densities of over 1000 ind.

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 ...

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,

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.
