A 20-year review of the status and distribution of African wild dogs (Lycaon pictus) in South Africa (Southern African Wildlife Management Association, 2020-02)South Africa is one of only seven countries with a viable population of African wild dogs (Lycaon pictus). The national population in 2017 was 372 adults and yearlings and comprised three subpopulations: 1) Kruger National ...

(AOSIS Open Journals, 2018-09-27)Vegetation mapping of protected areas is a cornerstone of conservation worldwide. Established in 1928 and covering over 1.4 million hectares, Hwange National Park (HNP) is the largest natural reserve in Zimbabwe. In 1993, ...
-
(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 ...
-
(Southern African Wildlife Management Association, 2019)The aardwolf (Proteles cristata) is a unique, insectivorous species of the family Hyaenidae. It occupies a disjunct range in eastern and southern Africa and is possibly a remaining member of a historical dog-like hyaena ...
-
(Wiley-Blackwell, 2012-09)Ticks are important vectors of pathogens of medical and veterinary importance worldwide. Despite their economic importance our current knowledge about the factors affecting tick prevalence and abundance in tropical and ...
-
(Entomological Society of America, 2014)Plant morphological changes mediated by growth conditions are linked to changes in host preference of herbivores. Understanding how these morphological changes influence herbivore feeding is critical in the interpretation ...
-
(NISC (Pty) Ltd and Informa UK Limited (trading as Taylor & Francis Group), 2021)The Antarctic blue whale Balaenoptera musculus intermedia was hunted to near extinction in the twentieth century. Current data on the abundance and distribution of the species are lacking owing to the difficulty and expense ...
-
(Elsevier, 2023-02)Abundance and trait-driven processes have both been identified as potential mechanisms in determining the occurrence of species interactions. However, little is known about how these two mechanisms interact to determine ...
-
(Inter-Research, 2011-05-05)Killer whales Orcinus orca are apex predators known to have important effects on marine ecosystems. A fundamental step towards understanding their role in ecosystems, and vital for their informed management and conservation, ...
-
(Public Library of Science, 2020-10)Coastally distributed dolphin species are vulnerable to a variety of anthropogenic pressures, yet a lack of abundance data often prevents data-driven conservation management strategies from being implemented. We investigated ...
-
(Wiley, 2022-06)Spatially synchronous fluctuations of animal populations have profound ecological consequences, especially in northern latitudes. Spatially coupled fluctuations are often seen in small rodent populations, albeit with ...
-
(Nordic Council for Wildlife Research, 2020)Killer whales, Orcinus orca, are a cosmopolitan species with large ecological and demographic variation across populations. Population-specific demographic studies are, therefore, crucial in accurately assessing the status ...
-
(BMC, 2021-05)BACKGROUND: Small-scale poultry farming plays a major role as a source of income for farmers through the sale of birds and eggs. Furthermore, in households’ poultry products are a valuable source of protein in the ...
-
(Frontiers Media, 2019-11-15)Flavan-3-ols including the monomeric catechin and the polymeric proanthocyanidins (PAs) are abundant phenolic metabolites in poplar (Populus spp.) previously described to protect leaves against pathogen infection. However, ...
-
(Elsevier, 2022-11)Anthropogenic underwater noise has been shown to negatively affect marine organisms globally; yet little to no noise research has been conducted in most African waters including South Africa's. This study aimed to ...

(Wiley, 2021-04)No abstract available.
-
(Taylor and Francis, 2015-05)Describing the repertoire of sounds produced by wild cetaceans is necessary for understanding their function, for acoustic population monitoring and for measuring the potential influence of anthropogenic impact. Geographic ...
-
(Inter Research, 2020-09)Descriptions of seasonal occurrence and behaviour of Antarctic blue and fin whales in the Southern Ocean are of pivotal importance for the effective conservation and management of these endangered species. We used an ...
-
(Transvaal Museum, 2015)A new apatetrine gelechiid, Acutitornus persectus spec. nov., is described from the Northern Cape province of South Africa. The larvae of this species develop in stem galls in Stipagrostis namaquensis (Nees) (Poaceae), a ...
-
(BioMed Central, 2011-05)BACKGROUND: Major Histocompatibility Complex (MHC) genes are central to vertebrate immune response and are believed to be under balancing selection by pathogens. This hypothesis has been supported by observations of extremely ...
