Resource partitioning between black-backed jackal and brown hyeana in Waterberg Biosphere Reserve, South Africa
(Canid Specialist Group, 2016)
Understanding resource partitioning by predators is important for understanding coexistence patterns, with this becoming more relevant as historical food webs are altered through human impacts. Using scat analysis, we ...
Identifying barriers to effective management of widespread invasive alien trees: Prosopis species (mesquite) in South Africa as a case study.
(Elsevier Ltd, 2016)
Biological invasions are a major driver of ecological and social change globally. The negative effects of these invasions have led to the initiation of programs to manage these invasions across the world. Management aims ...
South African National Survey of Arachnida: A checklist of the spiders(Arachnida, Araneae) of the Lekgalameetse Nature Reserve, Limpopo province, South Africa
The aim of the South African National Survey of Arachnida (SANSA) is to document the Arachnida fauna of South Africa. One of the focus areas of SANSA is to survey protected areas to obtain species-specific information, ...
Trophic ecology and persistence of invasive silver carp Hypophthalmichthys molitrix in an oligotrophic South African impoundment
(NISC (Pty) Ltd and Taylor & Francis, 2016)
The alien invasive silver carp Hypophthalmichthys molitrix established a self-sustaining feral population in an oligotrophic impoundment, Flag Boshielo Dam, in South Africa. The ability of this population to persist in a ...
Managing a threatened savanna ecosystem(KwaZulu-Natal Sandstone Sourveld) in an urban biodiversity hotspot: Durban, South Africa
Background: The city of Durban in the province of KwaZulu-Natal (KZN), South Africa, falls within a global biodiversity hotspot. KwaZulu-Natal Sandstone Sourveld (KZNSS) is a savanna vegetation type endemic to KZN. KZNSS ...
Capture the time when plants reach their maximum body size by using the beta sigmoid growth equation
(Elsevier B.V., 2016)
Of the many mathematical models proposed for capturing the dynamics of plant growth, the beta sigmoid function (BSF) is the newest and consequently is not well known to ecologists. A recent software package based on the ...
EMAPi 2015: Highlighting links between science and management of alien plant invasions
(Pensoft Publishers, 2016)
Historical costs and projected future scenarios for the management of invasive alien plants in protected areas in the Cape Floristic Region
(Elsevier Ltd., 2016)
Scarce funds for conservation need to be optimally used, yet there are few studies that record the costs and projected outcomes of major conservation efforts. Here we document the historical costs and extent of efforts to ...
Using functional responses to quantify interaction effects among predators
(British Ecological Society, 2016)
1. Predator diversity alterations have been observed in most ecosystems as a result of the loss and/ or addition of species. This has implications for predator–prey dynamics as non-trophic interactions among predators, ...
