Eavesdropping : how do vervet monkeys perceive the alarm calls of other species?.
(2013)Perceived predation risk has a large impact on how prey species utilise landscapes. In an effort to reduce predation risk, individuals tend to utilise safer areas more than unsafe areas. How perceived predation risk affects ... -
Ecological aspects and conservation of the invertebrate fauna of the sandstone caves of Table Mountain, Cape Town.
(1998)No abstract available. -
Ecological correlates : endophagous insects and plants in fynbos.
(1995)The objective of this study was to investigate endophagous insect species richness in Fynbos. The influences of plants as determinants of insect occurrence were given special attention. The endophagous insects associated ... -
Ecological effects of Festuca costata on the Drakensberg grasslands.
(2018)Fire and herbivory are important in determining the vegetation structure in savannas and grasslands. In addition, anthropogenic activities have significantly contributed to alterations in the relative abundance and ... -
Ecological effects of fire in the montane grasslands of Natal.
(1985)Although controlled burning has been used to manage Highland Sourveld grasslands, little was known of its effects on the vegetation. This study examined the effects of past fire treatments on veld condition,species ... -
Ecological factors influencing the reproductive ecology, territoriality and foraging behaviour of fiscal shrikes.
(1998)This thesis describes the behavioural ecology of South African fiscal shrikes through detailed field observations and experimental manipulations, and discusses these in the context of reproductive ecology, life history ... -
The ecological implications of sea-level rise and storms for sandy beaches in KwaZulu-Natal.
(2008)The aesthetic appeal of beaches has made coastal properties prime sites for development. However, this development has been mismanaged and is within the littoral active zone. Beaches retreat landwards as sea levels rise, ... -
An ecological investigation of the insects associated with exposed carcasses in the northern Kruger National Park : a study of populations and communities.
(1984)Extensive seasonal collections along with absolute counts of all the arthropods attracted to medium- and large mammal carcasses resulted in the most complete record of carrion-fauna in Africa to date. The abundance of ... -
Ecological studies of bottlenose and humpback dolphins in Maputo Bay, southern Mozambique.
(2008)The ecology and population biology of bottlenose and humpback dolphins inhabiting the Maputo Bay, Southern Mozambique were studied through boat based photoidentification surveys and behavioural methods between December ... -
Ecology and conservation of the Cape vulture in the Eastern Cape Province, South Africa.
(2016)Abstract available in PDF file. -
Ecology and behaviour of the Seychelles giant millipede.
(1999)On certain islands in the Seychelles archipelago a large and abundant animal is the Seychelles giant millipede, Seychelleptus seychellamm (Desjardins, 1834). This study quantifies the ecological role of this species in ... -
The ecology and conservation biology of Lilian's lovebird Agapornis lilianae in Malawi.
(2014)Despite their popularity, parrots are the world’s most threatened birds. Lovebirds (Agapornis) are very popular pet and aviary birds and as ecologically specialised species in the wild, they are also among the most threatened ... -
The ecology and conservation biology of the Black-cheeked Lovebird Agapornis nigrigenis in Zambia.
(2003)This study was undertaken to investigate the ecology of the Black-cheeked Lovebird Agapornis nigrigenis in the wild. Prior to this study little was known about the ecology of this parrot or other members of the genus ... -
The ecology and conservation of blue duiker and red duiker in Natal.
(1990)The ecology of blue duikers Philantomba monticola and red duikers Cephalophus natalensis was studied in three lowland coastal evergreen forests in Natal. Variation in population densities, estimated with numerous census ... -
Ecology and evolution of the specialized hemipepsis-wasp (Hymenoptera : Pompilidae) pollination guild in South Africa.
(2011)Pollinators are believed to have played a key role in the radiation of flowering plants. The Grant-Stebbins model of pollinator-mediated speciation, in which evolutionary shifts between pollinators result in phenotypic ... -
The ecology and parasitology of small mammals from selected sites in Swaziland.
(2007)The study was initially a long term study of the ecology of small mammals at Mlawula Nature Reserve in the eastern part of Swaziland. Due to the drought and dwindling numbers of rodents in the reserve the study was ... -
The ecology of Black Sparrowhawks (Accipiter melanoleucus) in KwaZulu-Natal, South Africa.
(2014)Black Sparrowhawks (Accipiter melanoleucus) are a medium-sized raptor found across much of sub-Saharan Africa. Within South Africa their distribution has historically been across most of the east with no distribution across ... -
The ecology of black-backed jackal (Canis mesomelas) on farmlands in the Midlands of KwaZulu-Natal, South Africa.
(2014)Agricultural development is progressively being attributed as a cause of biodiversity loss. Despite this development, some species do successfully inhabit these transformed habitats and benefit from increased food and ...
