Happy Feet in a Hostile World? The Future of Penguins Depends on Proactive Management of Current and Expected Threats
(2019)Penguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 penguin species are decreasing. Here we present a review that ... -
Hatch traits of artificially incubated ostrich eggs as affected by setting position, angle of rotation and season
(AJOL, 2020)High levels of hatching failure in artificially incubated ostrich eggs cause considerable loss of income for the industry. In the 2015 - 2016 breeding seasons, between 846 and 1 549 egg records were used to determine the ... -
Heavy metals in the irrigation water, soils and vegetables in the Philippi horticultural area in the Western Cape Province of South Africa
(Springer Verlag, 2014)The aims of this study were to investigate the extent of heavy metal contamination in the Philippi horticultural area in the Western Cape Province, South Africa. Concentrations of Cd, Cr, Cu, Mn, Ni, Pb and Zn were ... -
Heydrichia cerasina sp. nov. (Sporolithales, Corallinophycidae, Rhodophyta) from the southernmost tip of Africa. Phycologia, 51(1): 11- 21
(International Phycological Society, 2012)A new species of Heydrichia (Sporolithales), H. cerasina sp. nov., is described, found only on pebbles in the low intertidal zone along a 10 km stretch of the South African south coast from Cape Agulhas to Struisbaai. The ... -
High-depth African genomes inform human migration and health
(Choudhury, A. et al. (2021). Author correction: High-depth African genomes inform human migration and health (nature, (2020), 586, 7831, (741-748), 10.1038/s41586-020-2859-7). Nature, 592(7856), E26. doi:10.1038/s41586-021-03286-9, 2021)The African continent is regarded as the cradle of modern humans and African genomes contain more genetic variation than those from any other continent, yet only a fraction of the genetic diversity among African individuals ... -
Hitting the right target: taxonomic challenges for, and of, plant invasions
(Oxford University Press, 2013)This paper explores how a lack of taxonomic expertise, and by implication a dearth of taxonomic products such as identification tools, has hindered progress in understanding andmanaging biological invasions. It also ... -
How many species of angulate tortoises occur in Southern Africa? (Testudines: Testudinidae: Chersina)
(Wiley-Blackwell, 2020)Using range-wide sampling and 1,143 bp of mtDNA (cytochrome b gene) and 14 microsatellite loci, we examined genetic differentiation in the widely distributed Southern African angulate tortoise (Chersina angulata). We found ... -
How much leaf area do insects eat? A data set of insect herbivory sampled globally with a standardized protocol
(Ecological Society of America, 2021)Herbivory is ubiquitous. Despite being a potential driver of plant distribution and performance, herbivory remains largely undocumented. Some early attempts have been made to review, globally, how much leaf area is removed ... -
How to build science-action partnerships for local land-use planning and management: Lessons from Durban, South Africa
(Resilience Alliance, 2016)The gap between scientific knowledge and implementation in the fields of biodiversity conservation, environmental management, and climate change adaptation has resulted in many calls from practitioners and academics to ... -

Hydromedusae off the Orange River Mouth, Southern Africa
(NISC (Pty) Ltd and Taylor& Francis, 2003)A total of 242 zooplankton samples from the upper 100 m of the water column was collected discontinuously from March 1997 to January 1999 off the Orange River mouth on the west coast of southern Africa. Six species of ... -
Identifying global priorities for the conservation of vipers
(Elsevier, 2016)Vipers are among the most misunderstood and persecuted animals. They occupy most terrestrial ecosystems around the world, often at high population densities. However, certain aspects of their biology (e.g., low fecundity ... -
Impact of climate change and anthropogenic activities on renewable coastal resources and biodiversity in Nigeria
(Academic Journals, 2012)Climates related disaster is greatly human induced warming, leading to substantial fluctuations in earth temperature which is currently a global issue of environmental concern. Human proximity and pressure in and around ... -
Impacts of an invasive alien Proteaceae on native plant species richness and vegetation structure
(South African Journal of Botany, 2021)The influence of invasive alien plants on plant community structure and above ground biomass in their novel range is poorly understood, as the magnitude and direction of these effects are often species and ecosystem specific. ... -
Implementing value chain analysis to investigate drivers and sustainability of Cape Town's informal economy of wild-harvested traditional medicine
(Routledge, 2015)Despite a highly visible presence, policy-maker knowledge of the drivers and participants in the informal economy of wild-harvested medicinal plants in Cape Town remains limited. To illuminate the workings of this local ... -
Implications of the breakdown in the indigenous knowledge system for rangeland management and policy: A case study from the Eastern Cape in South Africa
(Taylor and Francis Group, 2023)Communal rangelands in South Africa are generally perceived as overgrazed owing to complexities in their histories and collective utilisation which often leads to improper management. A suitable ... -
The implications of the reclassification of South African wildlife species as farm animals
(South African Assn. For The Advancement Of Science, 2020)The Government Gazette No. 42464 dated 17 May 20191 amended Table 7 of the Animal Improvement Act (Act no. 62 of 1998), which lists breeds of animals, to include at least 32 new wild animal species, including 24 ... -
In a rough spot: Declines in Arthroleptella rugosa calling densities are explained by invasive pine trees
