Procavia capensis – Rock Hyrax
نویسنده
چکیده
Taxonomic notes: While as many as 17 subspecies have been described across its range by Hoeck and Bloomer (2013), only one (P. c. capensis), is recognised from the assessment region (Meester et al. 1986). However, Prinsloo and Robinson (1992) discovered a genetic break between the north-western and south-central populations in South Africa, indicating a possible species complex. Similarly, Visser (2013) found a genetic break across the Knersvlakte region; however this was only evident in the mitochondrial DNA (mtDNA, for females). Thus, separation across this barrier has not been long enough to warrant a Procavia capensis – Rock Hyrax

Elevated testosterone levels and social ranks in female rock hyrax.
In mammals, males maintain significantly higher testosterone (T, 'the male hormone') levels than females throughout the year and are typically dominant over females. Our study of the cooperatively breeding rock hyrax (Procavia capensis) demonstrated a distinct exception. In most hyrax social groups that we studied, adult females were at the highest social rank within the group and showed higher...
متن کاملNeocortical neuron morphology in Afrotheria: comparing the rock hyrax with the African elephant.
The mammalian neocortex contains a great variety of neuronal types. In particular, recent studies have shown substantial morphological diversity among spiny projecting neurons in species that diverged close to the base of the mammalian radiation (e.g., monotremes, afrotherians, and xenarthrans). Here, we used a Golgi technique to examine different neuronal morphologies in an afrotherian species...
متن کاملGeographic mitochondrial DNA variation in the rock hyrax, Procavia capensis.
Restriction-fragment-length polymorphisms in mitochondrial DNA (mtDNA) were used to evaluate geographic population genetic structure in the rock hyrax, Procavia capensis, a species which occurs widely, though restricted to rocky habitat, throughout South Africa. Ten restriction endonucleases were employed to assay mtDNAs from 55 specimens representing 10 localities. Haplotypes showed strong geo...
متن کاملSyntactic structure and geographical dialects in the songs of male rock hyraxes.
Few mammalian species produce vocalizations that are as richly structured as bird songs, and this greatly restricts the capacity for information transfer. Syntactically complex mammalian vocalizations have been previously studied only in primates, cetaceans and bats. We provide evidence of complex syntactic vocalizations in a small social mammal: the rock hyrax (Procavia capensis: Hyracoidea). ...
متن کاملRock hyrax (Procavia capensis) den site selection: preference for artificial sites
Context. Objective assessments of habitat requirements for endangered species are often lacking when planning management strategies, and inappropriate landscape manipulation can sometimes turn an endangered species into a pest. Recent expansive population growth of the rock hyrax Procavia capensis in northern Israel has been attributed largely to the proliferation of man-made boulder piles on t...
