Temporal partitioning of Bullacris unicolor (Orthoptera: Pneumoridae) calling activity to avoid predation
(Taylor and Francis Group, 2023)
Ecological interactions, including competition, predation, and environmental conditions, may significantly impact acoustic signal-ling behaviour. Here we characterise nocturnal signalling patterns in the bladder grasshopper ...
African rangelands and pastoralism in a changing continent: Perspectives and opportunities
(Taylor and Francis Group, 2023)
Eighty-five years ago, Africa was described as a land of promise because it provided an immense opportunity for maximum return in the minimum time (Olaniyan 2000). It was treated this way because ...
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
(Wiley, 2022)
Latitudinal range limits for mangroves on high-energy,
wave-dominated
coasts
are controlled by geomorphological features and estuarine dynamics. Mangroves
reach a southern global range limit along the South African ...
Iterative mapping of marine ecosystems for spatial status assessment, prioritization, and decision support
(Frontiers Media, 2023)
South Africa has taken an iterative approach to marine ecosystem mapping over
18 years that has provided a valuable foundation for ecosystem assessment,
planning and decision-making, supporting improved ecosystem-based ...
Is penguin circovirus circulating only in the antarctic circle? Lack of viral detection in namibia
(MDPI, 2023)
The known host range of circoviruses is continuously expanding because of more intensive diagnostic activities and advanced sequencing tools. Recently, a new circovirus (penguin
circovirus (PenCV)) was identified in the ...
Cross-shelf movement of chrysaora fulgida (scyphozoa; discomedusae) off namibia inferred from stable isotopes (δ15n and δ13c)
(Taylor and Francis Group, 2021)
Large and small specimens of two species of metagenic Scyphozoa (true jellyfishes) can be found in nearshore waters off central Namibia throughout the year. Whereas populations of Chrysaora ...
Nitrogen fertilization increases the growth and nutritional quality of the forage legume, Calobota sericea – A preliminary investigation
(Elsevier, 2023)
Calobota sericea is being evaluated as a forage for drought stressed areas. The nutritional quality
of C. sericea from native populations are poor, and this is believed to be due to poor soil fertility.
Therefore, a ...
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 ...
Initial evaluation of the care and rehabilitation success of Cape Cormorants Phalacrocorax capensis rescued from Robben and Jutten islands, South Africa, in January 2021
(Taylor and Francis Group, 2023)
The population of the endangered Cape Cormorant Phalacrocorax capensis more than halved over the last three decades (BirdLife International 2018a). In January 2021, nearly 2 000 Cape Cormorant chicks were ...
The diurnal activity budgets of extralimital giraffe (Giraffa camelopardalis giraffa) in the Western Cape Province, South Africa
(Wiley, 2023)
Despite being an extralimital species in the region, South African giraffes (Giraffa camelopardalis
giraffa, Schreber 1784) are continuously being introduced into the Albany
Thicket Biome of the Western Cape Province of ...
