Aethomys chrysophilus (Rodentia: Muridae)
(American Society of Mammalogists, 2008-06-08)The genus Aethomys currently includes 11 species, but recent evidence indicates a need for taxonomic revision of the genus. Aethomys chrysophilus (De Winton, 1897) is a muroid rodent commonly called the red veld rat. A ... -
Aethomys ineptus (Rodentia: Muridae)
(American Society of Mammalogists, 2008-06-06)Aethomys ineptus (Thomas and Wroughton, 1908), commonly called the Tete veld rat, is a medium-sized rodent with a long, sparsely haired tail and spermatozoa with spatulate-shaped heads (unique for all muroid rodents thus ... -
Ananlysis of gonadotrophin-releasing hormone-1 and kisspeptin neuronal systems in the nonphotoregulated seasonally breeding eastern rock elephant-shrew (Elephantulus myurus)
(Wiley Periodicals Inc., 2018)Of the 18 sub-Saharan elephant-shrew species, only eastern rock elephant-shrews reproduce seasonally throughout their distribution, a process seemingly independent of photoperiod. The present study characterizes gonadal ... -
Bartonellae of the Namaqua rock mouse, Micaelamys namaquensis (Rodentia: Muridae) from South Africa
(Elsevier, 2012)The aim of this study was to determine Bartonella prevalence and diversity in Namaqua rock mice, Micaelamys namaquensis, a species endemic to South Africa, which can attain pest status. A total of 100 heart samples ... -
A biogeographical assessment of anthropogenic threats to areas where different frog breeding-groups occur in South Africa: implications for anuran conservation
(Wiley Blackwell, 2012-04)Aim To determine the spatial relationship between areas where different frog breeding groups occur and elevated anthropogenic activities, and the conservation implications thereof. Location South Africa. Methods Data ... -
Bioregion heterogeneity correlates with extensive mitochondrial DNA diversity in the Namaqua rock mouse, Micaelamys namaquensis (Rodentia: Muridae) from southern Africa - evidence for a species complex
(BioMed Central Ltd., 2010)Background: Intraspecific variation within the diverse southern African murine rodents has not been extensively investigated, yet cryptic diversity is evident in several taxa studied to date. The Namaqua rock mouse, ... -
Broad niche overlap between invasive Nile tilapia Oreochromis niloticus and indigenous congenerics in Southern Africa: Should we be concerned?
(MPDI (Basel, Switzerland), 2015)This study developed niche models for the native ranges of Oreochromis andersonii, O. mortimeri, and O. mossambicus, and assessed how much of their range is climatically suitable for the establishment of O. niloticus, and ... -
Calibrating a camera trap-based biased mark-recapture sampling design to survey the leopard population in the N'wanetsi concession, Kruger National Park, South Africa
(John Wiley & Sons Ltd, 2013)Estimating large carnivore abundance can be challenging. A biased leopard (Panthera pardus) population survey was conducted in the N’wanetsi concession in the Kruger National Park (KNP), South Africa, using motion-sensitive ... -
Circadian rhythms of locomotor activity in the reddish-grey musk shrew (Eulipotyphla: Soricidae) from South Africa
(The Zoological Society of London, 2011)The circadian rhythm of locomotor activity in a southern African shrew, the reddish-grey musk shrew Crocidura cyanea was investigated. Thirteen individuals were subjected to three successive light cycles, each cycle lasting ... -
A comparative analysis of components incorporated in conservation priority assessments: a case study based on South African species of terrestrial mammals.
(2007-07-06)Assessing the risk of extinction to species forms an essential part of regional conservation initiatives that facilitate the allocation of limited resources for conservation. The present study conducted conservation priority ... -
Craniometric sexual dimorphism and age variation in the South African Cape dune mole-rat (Bathyergus Suillus)
(American Society of Mammalogists, 2007)Because absolute mammalian age is difficult to measure directly, various methods have been used for its estimation. Among these methods, the degree of molar eruption and wear are considered to be the most reliable indicators ... -
Dynamics of Rodent-Borne Zoonotic Diseases and Their Reservoir Hosts: Invasive Rattus in South Africa
(University of California, Davis., 2012)Lack of adequate sanitation and pest control, and poor housing conditions that prevail in much of both rural and urban South Africa, cause rodent populations to thrive, promoting contact with humans, which results in ... -
Ecological niche modeling of the invasive potential of Nile tilapia Oreochromis niloticus in African river systems: concerns and implications for the conservation of indigenous congenerics
(2013-06-30)This study applied ecological niche models to determine the potential invasive range of Nile tilapia, Oreochromis niloticus, with a particular focus on river systems in southern Africa where it is now established and ... -
Evidence of a contact zone between Rhabdomys dilectus(Rodentia: Muridae) mitotypes in Gauteng province, South Africa
(Zoological Society of Southern Africa, 2015)Recent studies have described the presence of several mitochondrial lineages within Rhabdomys, which was previously considered to be a monotypic genus. The exact distributional limits of the species and subspecies and their ... -
Faecal glucocorticoid metabolite concentrations and their alteration post-defaecation in African wild dogs, Lycaon pictus from South Africa
(BioOne, 2018)Non-invasive techniques for the monitoring of animal well-being, such as faecal hormone analysis, are increasingly becoming some of the most desirable methods for addressing practical conservation questions. Despite the ... -
Food web properties vary with climate and land use in South African streams
(2020)Land use intensification and climate change are two prominent drivers of variation in biological communities. However, we know very little about how these two potential environmental stressors interact. Here we use a stable ... -
Genetic identification of freely traded synanthropic invasive murid rodents in pet shops in Gauteng Province, South Africa
(2020)Although synanthropic invasive murid rodents are freely traded in pet shops in South Africa, their taxonomic identities, however, remain largely unknown. Twenty-four murid rodents were sampled from pet shops in four of the ... -
Genetic monitoring detects an overlooked cryptic species and reveals the diversity and distribution of three invasive Rattus congeners in South Africa
(BioMed Central, 2011)Background: South Africa’s long and extensive trade activity has ensured ample opportunities for exotic species introduction. Whereas the rich biodiversity of endemic southern African fauna has been the focus of many ... -
Geometric craniometric analysis of sexual dimorphism and ontogenetic variation: A case study based on two geographically disparate species, Aethomys ineptus from southern Africa and Arvicanthis niloticus from Sudan (Rodentia:Muridae)
(ElsevierGmbH., 2009)Non-geographic morphometric variation, particularly at the level of sexual dimorphism and ontogenetic (age-related) variation, has been documented in rodents, and useful for establishing whether to analyse sexes separately ...
