Hugo, Sanet; Janse Van Rensburg, Berndt; Van Wyk, Abraham Erasmus (Braam); Steenkamp, Yolande (Public Library of Science, 2012-05-04)The distributions of naturalised alien plant species that have invaded natural or semi-natural habitat are often geographically restricted by the environmental conditions in their new range, implying that alien species ...
-
Kalwij, Jesse M.; Robertson, Mark P.; Janse Van Rensburg, Berndt (Springer, 2015-12)There is increasing evidence that invasive species are threating montane ecosystems globally. However, trends in species distribution are difficult to observe directly due to a lack of data with suitable spatio-temporal ...

Bishop, Tom R.; Robertson, Mark P.; Gibb, Heloise; Janse Van Rensburg, Berndt; Braschler, Brigitte; Chown, Steven L.; Foord, Stefan H.; Munyai, Thinandavha Caswell; Okey, Iona; Tshivhandekano, Pfarelo G.; Werenkraut, Victoria; Parr, Catherine Lucy (Wiley, 2016-12)AIM : In ectotherms, the colour of an individual’s cuticle may have important thermoregulatory and protective consequences. In cool environments, ectotherms should be darker, to maximize heat gain, and larger, to ...
-
Janse Van Rensburg, Berndt; Hugo, Sanet; Levin, Noam; Kark, Salit (Wiley-Blackwell, 2013-03)AIM To examine whether at a subcontinental-scale ecotonal areas of transition between vegetation communities are at higher risk of plant invasion. LOCATION South Africa and Lesotho. METHODS Using plant data on native ...

Robertson, Mark P.; Harris, K.R. (Kyle Robert); Coetzee, Julie A.; Foxcroft, Llewellyn C.; Dippenaar-Schoeman, Anna S. (Anna Sophia), 1948-; Janse Van Rensburg, Berndt (Zoological Society of Southern Africa, 2011-10)There is a paucity of studies examining direct impacts of introduced alien species on biodiversity, a key need for motivating for alien species control in conservation areas. The introduced prickly pear (Opuntia stricta) ...
-
Davies, Andrew Byron; Eggleton, Paul; Janse Van Rensburg, Berndt; Parr, Catherine Lucy (Wiley-Blackwell, 2013-04)Although termites are ecosystem engineers in tropical and sub-tropical environments, the study of termite ecology is often constrained by sampling difficulties and a lack of established sampling protocols, particularly for ...
-
Mokhatla, Mohlamatsane M.; Measey, G. John; Chimimba, Christian Timothy; Janse Van Rensburg, Berndt (Wiley-Blackwell, 2012-05)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 on ...
-
Janse Van Rensburg, Berndt; Peacock, Derick S.; Robertson, Mark P. (Elsevier, 2009)Similar to the process seen in invasion biology, urbanized environments lead to biotic homogenization with a few species, often alien, dominating the urban habitat. We investigated avian communities across an urban gradient ...
-
Bishop, Tom R.; Robertson, Mark P.; Janse Van Rensburg, Berndt; Parr, Catherine Lucy (Wiley, 2015-09)AIM : Beta diversity describes the variation in species composition between sites and can be used to infer why different species occupy different parts of the globe. It can be viewed in a number of ways. First, it can ...

Berthouly-Salazar, Cecile; Cassey, Phillip; Jansen van Vuuren, Bettine J.; Janse Van Rensburg, Berndt; Hui, Cang; Gardner, Michael G.; Le Roux, J.J. (Johannes Jacobus) (Springer, 2012)We used a next generation sequencing (NGS) approach to screen for genome-wide nuclear microsatellite loci in the common (Indian) myna, Acridotheres tristis. In addition, markers previously developed for other ...
-
Peacock, Derick S.; Janse Van Rensburg, Berndt; Robertson, Mark P. (Academy of Science of South Africa, 2007-11)The common myna is an Asian starling that has become established in many parts of the world outside of its native range due to accidental or deliberate introductions by humans. The South African population of this species ...
-
Filer, Alannah; Meyer, Edward A.; Janse Van Rensburg, Berndt (Wiley, 2022-11)Coastal wallum wetlands inhabited by the vulnerable wallum sedgefrog (Litoria olongburensis) are highly susceptible to habitat degradation owing to their unusual hydrology and water chemistry. Anthropogenic impacts on ...
-
Asefa, Addisu; Davies, Andrew Byron; McKechnie, Andrew E.; Kinahan Anouska A.; Janse Van Rensburg, Berndt (American Ornithological Society, 2017-06)The Afromontane forests of Ethiopia are global biodiversity hotspots, known for their high biological diversity and endemism. However, conservation of these areas is challenging due to increasing human threats, including ...
-
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 ...
-
Bishop, Tom R.; Robertson, Mark P.; Janse Van Rensburg, Berndt; Parr, Catherine Lucy (Wiley, 2014-12)AIM Patterns of biological diversity are often investigated across space but little work has attempted to explore the consistency of such observations through time. Here, our aim was to understand the patterns of diversity ...
-
Greve, Michelle; Gaston, Kevin J.; Janse Van Rensburg, Berndt; Chown, Steven Loudon (Blackwell, 2008)AIM: To determine how well variation in median body size of avian assemblages is predicted by (1) the environmental models usually employed in analyses of Bergmann's rule and (2) random sampling from the regional body ...
-
Teixeira, Daniella; Linke, Simon; Hill, Richard; Maron, Martine; Janse Van Rensburg, Berndt (Elsevier, 2022-07)Ecologists are increasingly using bioacoustics in wildlife monitoring programs. Remote autonomous sound recorders provide new options for collecting data for species and in contexts that were previously difficult. However, ...
-
Kalwij, Jesse M.; Robertson, Mark P.; Janse Van Rensburg, Berndt (Opulus Press Uppsala, 2008)QUESTION: Do anthropogenic activities facilitate the distribution of exotic plants along steep altitudinal gradients? LOCATION: Sani Pass road, Grassland biome, South Africa. METHODS: On both sides of this road, presence ...
-
Dalerum, Fredrik; Retief, Tarryn Anne; Havemann, Carl Peter; Chimimba, Christian Timothy; Janse Van Rensburg, Berndt (Wiley Open Access, 2019-01)Studies of biodiversity along environmental gradients provide information on how ecological communities change in response to biotic and abiotic factors. For instance, distance to water is associated with several factors ...
-
Davies, Andrew Byron; Janse Van Rensburg, Berndt; Eggleton, Paul; Parr, Catherine Lucy (Springer, 2013-05)One of the many ecological processes expected to undergo alteration due to global change is the decomposition of organic matter, with little known concerning the effects that changing disturbance regimes may have. Fire, a ...
