Van Aarde, Rudi J.; Pimm, Stuart L.; Guldemond, Robert Abraham Rene; Huang, Ryan M.; Mare, Celeste (PeerJ, 2021-01-11)The cause of deaths of 350 elephants in 2020 in a relatively small unprotected area of northern Botswana is unknown, and may never be known. Media speculations about it ignore ecological realities. Worse, they make ...

Ferreira, Sam M.; Van Aarde, Rudi J. (South African Wildlife Management Association, 2009-10)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 ...
-
Trimble, Morgan Jayne; Van Aarde, Rudi J.; Ferreira, Sam M.; Norgaard, Camilla F.; Fourie, Jo; Lee, Phyllis C.; Moss, Cynthia J. (Public Library of Science, 2011-10-19)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 ...
-
Trimble, Morgan Jayne; Van Aarde, Rudi J. (Wiley, 2014-10)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 ...
-
Ott, Theresia; Van Aarde, Rudi J. (Springer, 2014-01)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 ...

De Flamingh, Alida; Ishida, Yasuko; Pecnerova, Patrícia; Vilchis, Sahara; Siegismund, Hans R.; Van Aarde, Rudi J.; Malhi, Ripan S.; Roca, Alfred L. (Frontiers Media, 2023-01-12)Non-invasive biological samples benefit studies that investigate rare, elusive, endangered, or dangerous species. Integrating genomic techniques that use non-invasive biological sampling with advances in computational ...

Mole, Michael Austin; DAraujo, Shaun Rodrigues; Van Aarde, Rudi J.; Mitchell, Duncan; Fuller, Andrea (Oxford University Press, 2016)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 ...

Mashintonio, Andrew F.; Pimm, Stuart L.; Harris, Grant M.; Van Aarde, Rudi J.; Russell, Gareth J. (PeerJ, 2014-08-19)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 ...
-
Trimble, Morgan Jayne; Van Aarde, Rudi J. (Public Library of Science, 2011-01)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 ...
-
Guldemond, Robert Abraham Rene; Louw, Cornelius J.; Mare, Celeste; Norgaard, Camilla; Van Aarde, Rudi J. (Wiley, 2022-08)Disturbances that change population structure may evoke transient dynamics that can be assessed within a demographic resilience framework. Conservation management interventions are conceptually disturbances that can be ...
-
Rolo, Victor; Olivier, Pieter Ignatius; Van Aarde, Rudi J. (Wiley, 2018-07)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? LOCATION ...
-
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 ...
-
Van Aarde, Rudi J.; Ferreira, Sam M. (Cambridge University Press, 2009)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 ...

Morley, R.C. (Robert Carl); Van Aarde, Rudi J. (Blackwell, 2007-04)Please open article to read abstract
-
Trimble, Morgan Jayne; Van Aarde, Rudi J. (American Institute of Biological Sciences, 2010-07)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, South ...

Functional connectivity within conservation networks : delineating corridors for African elephants 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 ...

Rolo, Victor; Olivier, Pieter Ignatius; Pfeifer, Marion; Van Aarde, Rudi J. (Elsevier, 2018-01)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 ...
