Economic growth and land use change: implications for global biodiversity.
This study examines whether land use change and biodiversity loss conform to an environmental Kuznets curve, a relationship in which certain environmental impacts increase then decrease with economic growth. The study draws on the experience of economic structural change to show that agricultural …

Endemism and richness in the Cape floristic region: phytogeographic patterns and environmental correlates in a global biodiversity hotspot
… species 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 …

The international convention for the control and management of ships' ballast water and sediments 2004: a critical appraisal
… supply comes from the sea, while the majority of global biodiversity and over 97 per cent of the biosphere is marine and is unknown. Invasive marine species are one of the four major threats to the world's oceans; the other three major threats are land-source marine pollution, over-exploitation of …

Late Quaternary palaeoenvironments of the southern Cape, South Africa palynological evidence from three coastal wetlands
… region 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 …

Weaving through the matrix: investigating the influence of urban land use on weaver bird movements into and out of Cape Town wetlands
… sites 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 …

From camera traps to conservation: biodiversity and mammal functional diversity in the Langkloof Corridor, Eastern Cape province, South Africa
ENGLISH ABSTRACT: The global biodiversity crisis has intensified the urgency of conservation strategies that extend beyond traditional protected areas. International frameworks such as the Convention on Biological Diversity’s Global Biodiversity Framework (GBF) calls for protecting 30% of the …

Increased phenotypic plasticity linked to broader geographic range size in sunflower (Helianthus) species
Human activity worsens global biodiversity loss, particularly for vulnerable rare species. Plant species can respond to environmental changes via adaptation and/or acclimation or migration, yet limited genetic diversity and fitness in rare species can hinder these processes. Changes in light …

A Global Conservation Assessment of Temperate Forests: Status and Protection
Global biodiversity protection requires the development of protected areas that include representative samples of different ecosystems and their associated biodiversity (Dudley 1992, Scott et al. 2001a). I compared long-term decline and protection of forests in three major biomes; boreal, temperate …

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 …

Assessing the Live Bait Industry and the Ecological Status of Invasive Cyprinodontiformes (Sheepshead minnow: Cyprinodon variegatus and Gulf killifish: Fundulus grandis) in Texas Streams
… species is one of the greatest threats to global biodiversity. Once established, invasive species often cause irreversible ecological damage on native communities. Here, I investigated the pathway of introduction and ecological impacts of the sheepshead minnow (<em>C. variegatus</em>) and …

Biodiversity and Biogeography of Deep-Sea Gastropod Mollusks from the Pacific Costa Rica Margin
… vents and hydrocarbon seeps, represent biodiversity hotspots along the ocean floor. Yet, investigations into the diversity, genetic connectivity, and biogeography of life at such ecosystems are still ongoing. The present dissertation explores the diversity and biogeography of deep-sea …

A GIS-Based Landscape Scale Model for Native Bee Habitat
… because it threatens food supplies and global biodiversity. An alternative to alleviating the effect of a honey bee shortage could be to use native bees. Problems with adoption of native bees in agriculture occur because of a lack of large scale analysis methods for native bees, regional …

Effects of anthropogenic change on animal cognition and emotion
Human activity is driving global biodiversity loss. However, the effects on animal cognition and emotion are less studied. In this thesis, I argue that anthropogenic change impacts animals’ mental states, with implications for both individuals (welfare) and populations (conservation). My first …
