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 ...
Net effects of multiple stressors in freshwater ecosystems: a meta-analysis
(John Wiley & Sons Ltd, 2016)
The accelerating rate of global change has focused attention on the cumulative impacts of novel and extreme environmental changes (i.e. stressors), especially in marine ecosystems. As integrators of local catchment and ...
Seasonal changes in reproductive development in male spiny mice (Acomys spinosissimus) from South Africa
(Elsevier, 2012)
Seasonal reproduction is a common characteristic of many small mammals which inhabit seasonal environments
in temperate regions, the sub-tropics as well as the tropics. It is important for an animal to
reproduce during ...
Trophic interrelationships between the exotic Nile tilapia, Oreochromis niloticus and indigenous tilapiine cichlids in a subtropical African river system (Limpopo River, South Africa)
(Springer, 2011)
The stable isotope ratio and seasonal changes
in diet of two indigenous (Oreochromis mossambicus,
Tilapia rendalli) and one exotic (Oreochromis niloticus)
tilapiine cichlids in the subtropical Limpopo
River, South ...
The locomotory activity rhythm of the spiny mouse, Acomys spinosissimus from southern Africa: Light entrainment and endogenous circadian rhythms
(Zoological Society of London, 2012)
The circadian rhythm of locomotor activity in the spiny mouse Acomys spinosissimus
from South Africa was investigated under controlled laboratory conditions.
Nine individuals were subjected to six successive light cycles ...
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 ...
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 ...
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 ...
The hippocampus of the eastern rock sengi: cytoarchitecture, markers of neuronal function, principal cell numbers, and adult neurogenesis
(Open Access Publishing, 2013-10)
The brains of sengis(elephant shrews, order Macroscelidae)have long been known to contain a hippocampus that in terms of allometric progression indices is larger than that of most primates and equal in size to that of ...
Spatio-temporal separation between lions and leopards in the Kruger National Park and the Timbavati Private Nature Reserve, South Africa.
(Elsevier B.V., 2015)
Understanding of the underlying processes that drive coexistence among apex predators
is of great importance to landscape managers overseeing their persistence. Two pressing
questions stand out. These questions relate ...
