Incorporating costs and processes into systematic conservation planning in a biodiversity hotspot
… with which to stem the rapid destruction of biodiversity, conservationists must set clear priorities for action. Systematic Conservation Planning (SCP) is an approach that uses spatially explicit data to identify areas that meet conservation targets efficiently, usually focusing on species’ …

Diversity patterns and conservation priorities in the "Mountains of Central Asia" biodiversity hotspot
The biodiversity hotspot concept prioritises regions where exceptional concentrations of endemic vascular plant species coincide with high vulnerability, thereby guiding global conservation efforts. Within this framework, the biodiversity hotspot “Mountains of Central Asia” (MoCA) represents a …

Endemism and richness in the Cape floristic region: phytogeographic patterns and environmental correlates in a global biodiversity hotspot
… rich Cape Floristic Region (CFR), a global biodiversity hotspot in South Africa. Modern Analytical techniques, including a novel approach developed within this study, were used to identify Phytogeographical Centres. Moreover, the efficiency and optimality of these techniques were tested …

Wild carnivore habitat use and community ecology in a biodiversity hotspot and human-wildlife conflict with pumas and dogs across Chile
… highlight threats that free-ranging dogs pose to biodiversity conservation and even human public health. I also used single-species, single-season occupancy models fit to camera-trap data to investigate the patterns of site occupancy and response to mega-wildfires of native mesocarnivores in …

Mapping Plant Biodiversity Hotspots at the County Scale: A New Tool for Establishing Resource Conservation Strategies
<p>Myers first identified the world’s 25 biodiversity hotspots and pioneered innovative ideas about the usefulness of biodiversity models for establishing long-term resource conservation strategies at global scales. Since Myers, most of the subsequent studies using hotspot science for biodiversity …

Late Quaternary palaeoenvironments of the southern Cape, South Africa palynological evidence from three coastal wetlands
… as it encompasses the Fynbos Biome, a global biodiversity hotspot, as well as rare Afrotemperate forest patches and is therefore of great botanical importance. As this area includes the transition from southern Africa’s winter rainfall zone to the year-round rainfall zone, it is also important …

Weaving through the matrix: investigating the influence of urban land use on weaver bird movements into and out of Cape Town wetlands
… in Cape Town, a growing city within a global biodiversity hotspot. Weaver bird movement data from 42 wetland sites were obtained through a long term mark - release - recapture project. Distance - based linear models revealed that site proximity was important as a predictor of weaver movement …

INVESTIGATION INTO THE INDIVIDUAL AND COMBINED IMPACTS OF WILDLIFE TRADE AND HABITAT LOSS ON BIODIVERSITY AND CONSERVATION INTERVENTIONS INTHE TROPICS
… two economic drivers of environmental change and biodiversity decline, wildlife trade and habitat loss. My first data chapter explores how socio-economic factors undermine protected areas by studying the spatial occurrence of protected area downgrading, downsizing and degazettement. Next, I apply …

The role of hydraulic strategies in understanding the response of fynbos to drought
… concern in South Africa’s fynbos biome, a global biodiversity hotspot. This Mediterranean-type region is predicted to experience an increase in drought, with unknown consequences for the endemic flora. We asked whether drought affected this diverse ecosystem in a predictable manner and if these …

Physiological tolerances of high temperatures in Fynbos birds: implications for climate change
… change. The Fynbos biome of South Africa is a biodiversity hotspot and is home to a rich birdlife, including six endemic bird species. Climate change models predict an increase in temperature for this biome, which may alter the ranges of many of these species, resulting in a loss of species …

Using primates to establish priority conservation sites in Mexico.
… we invest those resources in areas with great biodiversity value. The Uxpanapa Valley in Mexico is one of Mesoamerica's largest forest remnants, is considered as a main biodiversity hotspot and has recently been established as a Protected Area. However, only minimal research has been conducted …

Relationships between conservators, community partners and urban conservation areas: a case study of nature reserves on the Cape Flats
Cape Town is a unique city. It has a global biodiversity hotspot, in the midst of an urban area. Historically, nature conservation practice excluded and marginalized certain groups of people based on their race and class. This has led to peoples� disconnection from nature. Rapid biodiversity loss …

Ecological, Social, And Educational Dimensions Of Restoration: Insights From Berenty Reserve, Madagascar
Amidst a global biodiversity crisis, ecological restoration emerges as a critical solution to mitigate the devastating effects of biodiversity loss and climate change. Focusing on Madagascar, a biodiversity hotspot facing significant forest loss, this dissertation explores various aspects of …
