Population estimates based on strip transect aerial surveys of large herbivores can aid
management decisions if estimates are accurate and precise. Because sampling intensities may influence precision, we simulated survey ...

Determining the age of individuals in a population can lead to a better understanding of population dynamics through age
structure analysis and estimation of age-specific fecundity and survival rates. Shoulder height has ...
Kinahan, A.A.; Pimm, Stuart L.; Van Aarde, Rudi J.(Elsevier, 2007-01)
Elephants occur in landscapes where temperatures can reach 50 °C. Due to their large size they may face physiological problems of dissipating heat during such high temperatures. In spite of this, no one seems to have ...

Information on the response of herpetofauna to different land uses is limited though important
for land-use planning to support conservation in human-modified landscapes. Though
transformation is dogmatically associated ...
Robson, Ashley S.; Van Aarde, Rudi J.(Wiley, 2018-08)
In conservation, adaptive management relies on the assessment of past actions to improve conservation efficiencies in the future. Conservation management approaches for African elephants have recently changed, however ...

Topography is rarely considered as an independent
goal of restoration. However, topography determines
microenvironmental conditions and hence living
conditions for species. Restoring topography may therefore
be an ...

Most of southern Africa’s elephants inhabit environments where environmental temperatures exceed body temperature,
but we do not know how elephants respond to such environments. We evaluated the relationships between ...

Setting conservation goals and management objectives relies on understanding
animal habitat preferences. Models that predict preferences combine location data
fromtracked animals with environmental information, usually ...

Previous studies demonstrate that old-growth forest remnants and vegetation regenerating after anthropogenic
disturbance provide habitat for birds in a human modified coastal dune forest landscape in northern KwaZulu-Na ...

QUESTIONS : What drives canopy gap formation in regenerating coastal dune forest? Does canopy gap size frequency distribution differ between new and old‐growth forests? Can canopy gaps divert regenerating trajectories?
Van Aarde, Rudi J.; Neluvhalani, M.J.; Ferreira, Sam M.; Verwoerd, Daniel Wynand(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1995)
Maintenance, expressed as change in daily body mass, and survival rates of Mastomys natalensis (sensu lato) were recorded from May to September 1994 in laboratory feeding trials, to investigate the short-term effects of a ...
Wilson, John W.; Van Aarde, Rudi J.; Janse Van Rensburg, Berndt(NISC, 2007)
We investigated the influence of forest fragment size and isolation on the bird assemblages in the species- and endemic-rich
sand forests of the Maputaland Centre of Endemism, southern Mozambique. Point-centre surveys ...

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) regulates trade in species and their products. The original listing of the African elephant (Loxodonta africana) in Appendix II ...

Licht and colleagues (BioScience 60:
147–153) identify South Africa’s pioneering
efforts to reintroduce top
predators to small, fenced protected
areas as a conservation model America
might be wise to follow. However,
Roever, Carrie Lynn; Van Aarde, Rudi J.; Leggett, K.(Elsevier, 2013-01)
Managing multiple parks, reserves, and conservation areas collectively as conservation
networks is a recent, yet growing trend. But in order for these networks to be ecologically
viable, the functional connectivity of ...
Changes in structure and functioning of tree communities in response to forest fragmentation may alter tropical forest’s capacity to store carbon and regulate climate. However, evidence for indirect effects of forest ...
Roever, Carrie Lynn; Van Aarde, Rudi J.; Leggett, K.(Wiley, 2012)
Resource selection function (RSF) models are commonly used to quantify species/ habitat
associations and predict species occurrence on the landscape. However, these models are
sensitive to changes in resource availability ...
De Flamingh, Alida; Sole, Catherine L.; Van Aarde, Rudi J.(Springer, 2015-06)
Earlier studies on savannah elephants (Loxodonta
africana) investigated the genetic structure of
fragmented or isolated populations. Contrastingly, this
study aimed to determine if there was genetic evidence for
