Aonyx capensis

  title={Aonyx capensis},
  author={Serge Larivi{\'e}re},
CONTEXT AND CONTENT. Order Carnivora, family Mustelidae, subfamily Lutrinae. The genus Aonyx is monophyletic and phylogenetically linked to the New World otters (Lontra—van Zyll de Jong 1987), with Paraonyx recognized as a valid subgenus (Ellerman et al. 1953). Exactly which species should be included in the genus Aonyx is not resolved. For example, the Asian smallclawed otter (Amblonyx cinerea) is often included in the genus Aonyx (Chanin 1985; Foster-Turley et al. 1990), but recent… 

Lutrinae Bonaparte, 1838 (Carnivora, Mustelidae) from the Plio-Pleistocene of the Lower Omo Valley, southwestern Ethiopia: systematics and new insights into the paleoecology and paleobiogeography of the Turkana otters

We describe otter remains (Lutrinae Bonaparte, 1838) from the Plio-Pleistocene of the Lower Omo Valley of southwestern Ethiopia. We report isolated lower and upper teeth of Torolutra sp. dated to c.

Establishing the foundation for an applied molecular taxonomy of otters in Southeast Asia

A multigene data set comprised of segments from 13 nuclear and 5 mitochondrial loci was used to develop a provisional set of diagnostic nucleotides that can be potentially used to identify the four species of Southeast Asian otters from noninvasively collected biological samples, such as feces.

Re-evaluation of the species composition of Bashkirovitrema Skrjabin, 1944 (Digenea: Echinostomatidae), with the description of two new species of this genus and the proposal of Kostadinovatremanovaeguiniense n. g., n. sp.

A comparison of specimens previously identified as Bashkirovitrema incrassatum from the African or cape clawless otter Aonyxcapensis, and the speckle-throated or spotted- Throated otter Hydrictismaculicollis from the Old World with specimens and descriptions of B. incrASSatum fromThe New World showed that those from Africa had a more extensive distribution of the vitelline fields than either B. canadense n.

First fossil small-clawed otter, Amblonyx, with a note on some specimens of Lutra, from the Upper Siwaliks, India

Otter-like mammals have been reported from the Indian sub-continent for more than a century and a half. Enhydriodontini are far more common and have a longer fossil record than either Lutrini or

Chapter 15 The Mammals of Angola

Scientific investigations on the mammals of Angola started over 150 years ago, but information remains scarce and scattered, with only one recent published account. Here we provide a synthesis of the

Carnivoran Evolution: Tiptoeing through the trophics: geographic variation in carnivoran locomotor ecomorphology in relation to environment

Taken together, these two observations suggest that a simple index of digitigrady calculated either for a single species or an entire fauna across a broad geographic range could reveal variation in palaeocommunity types.

Genetic diversity of African clawless otters (Aonyx capensis) occurring in urbanised areas of Gauteng, South Africa

Genetic diversity is the basis of the evolutionary potential of species to respond to environmental changes. However, restricting the movement of species can result in populations becoming less

Temporal Change in Functional Richness and Evenness in the Eastern African Plio-Pleistocene Carnivoran Guild

It is concluded that climate change is unlikely to explain all of the changes found and suggested that the evolution of early hominins into carnivore niche space, especially the Evolution of derived dietary strategies after 2 Ma, played a significant part in the reduction of carnivore functional richness.

Diet analysis of the African clawless otter (Aonyx capensis) in and around Lake Tana

A dietary flexibility and shift in the African clawless otter from crabs to fish that can be explained by availability and accessibility is suggested.



A phylogenetic study of the Lutrinae (Carnivora; Mustelidae) using morphological data

The phylogenetic relationship of the 13 extant species of otters were analyzed by canonical variate analysis using mensural data and by Wagner analysis using qualitative characters, showing a high degree of concordance.

Phylogenetic relationships of otters (Carnivora: Mustelidae) based on mitochondrial cytochrome b sequences

This work evaluates the relationships among nine of the 13 species of otters and their position in the Mustelidae through phylogenetic analysis of the complete nucleotide sequence of the mitochondrial cytochrome b gene and indicates that among sampled mustelid taxa, members of the genus Mustela are most closely related to otters.

The distribution of Mammals in Natal. Part 2. Carnivora

The distribution patterns of the following thirty-one species of mammals are recorded: Proteles cristatus, Aonyx capensis, Lutra maculicollis, Mellivora capensis, Ictonyx capensis, Poecilogale

Quantitative Estimations of Populations of the River Crab, Potamon (Potamonautes) perlatus (M. Edw.), in Rhodesian Trout Streams

Preliminary Rhodesian studies indicate that the river crab occurs in trout stomachs with a median percentage frequency occurrence and there is a 100.0 per cent frequency and 97.5 per cent volumetric occurrence in droppings of the clawless otter, Aonyx capensis Schinz.

Trophic overlap between three syntopic semi‐aquatic carnivores: Cape clawless otter, spotted‐necked otter and water mongoose

Summary Drought conditions in the Eastern Cape Province, South Africa, from 1990 to 1993 caused much of the Bushmans River to dry up, thus forcing Cape clawless otters Aonyx capensis (Schinz),

Crabs Potamonautes perlatus in diet of Otter Aonyx capensis and Water mongoose Atilax paludinosus in a freshwater habitat in South Africa

Studied the feeding ecology of sympatric Cape clawless otter and water mongoose at the Olifants River, Cape Province to determine the extent of dietary overlap.

Prey of the Cape clawless otter (Aonyx capensis) in the Tsitsikama Coastal National Park, South Africa

It was concluded that otters are opportunistic feeders with a good ability to capitalize on available prey, but along the Tsitsikama coast this was also due to the fact that no change in hunting method (used inland) was necessary.

Food Ecology of Otters in Natal, South Africa

It was concluded that small fish (< 200 mm) were easier to capture than larger ones, and were more abundant in otters' diets.

Observations on the food and status of the Cape clawless otter Aonyx capensis at Betty’s Bay, South Africa

The feeding ecology and status of Cape clawless otters were studied from April to December 1984 at Betty’s Bay, South Africa, and compared to similar studies along the Tsitsikama coast. Enough food,

Feeding habits of the Water mongoose (Atilax paludinosus)

Water mongooses are solitary, nocturnal herpestines that are found mainly in close proximity to water. The diet of free-living mongooses was assessed through scat analysis. Results show crabs to be
