Maximising Return on Investment for Species Conservation
… crucial to the action plans that governments and conservation organizations are developing to prevent species from going extinct. A Return on Investment (ROI) approach that explicitly incorporates the costs, benefits and risks of investment has been shown to improve the effectiveness and …

Developing a gene model for simulations that incorporates multi-species conservation
… mutations was modeled by utilizing the cross-species conservation of each region. The combined distribution of variants by their frequency over 500 genes was compared between the simulated genes and the corresponding empirical data. This distribution of variants between the simulated and …

Investigating Determinants of Collaboration between Landowners and Wildlife Agencies for Endangered Species Conservation
… is critical to accomplishing endangered species conservation (ESC) goals because of the large amounts of terrestrial land held in private ownership. To increase ESC collaboration above and beyond the deficiencies perpetuated by status quo command-and-control approaches, agencies have …

Managing open habitats for species conservation : the role of wild ungulate grazing, small-scale disturbances, and scale
… has caused a dramatic loss of habitats and species. In Central Europe, open habitats are particularly affected. The main objective of this thesis was to experimentally test the suitability of wild megaherbivore grazing as a conservation tool to manage open habitats. We studied the effect of …

An Assessment of Caribou (Rangifer tarandus) Genomic Diversity and Structure in Western Canada to Guide Species Conservation and Management
… have made it increasingly difficult for species to adapt and survive. The use of genomic technologies, such as the inference of genetic structure, can aid species conservation and prevent population declines. Particularly for caribou (Rangifer tarandus), which are considered an at-risk …

CHROMOSOME-LEVEL DE NOVO GENOME ASSEMBLIES OF AVIAN SPECIES AND THEIR RELEVANCE FOR COMPARATIVE GENOMICS, PANGENOMICS, POPULATION GENOMICS AND SPECIES CONSERVATION.
… the sixth mass extinction. A major loss of species is being caused by anthropogenic habitat destruction, illegal wildlife trade, overfishing, massive fossil fuel consumption and the consequent climate changes, leading to a progressive collapse of biodiversity. The establishment of …

Behavioural ecology and conservation of the Anosy mouse lemur (Microcebus tanost) in the littoral forests of southeastern Madagascar
… tanosi) and to relate these new insights to species conservation in the littoral forests of Sainte Luce. The littoral forests of southeast Madagascar represent a distinct phytogeographic habitat, characterised by tremendous species richness and floristic diversity, however, they have been …

Demographic and genetic variability in Cape Dwarf Chameleons, Bradypodion pumilum, withink a fragmented, urban habitat
… maintenance, researchers in the field of conservation biology often investigate population demography and genetic variability for species inhabiting fragmented landscapes. Findings from such work enable effective conservation management, maximizing viability for potentially imperiled …

Geographic range dynamics of South Africa's bird species
A key issue in species conservation is a knowledge of the geographic ranges of species, and how these are changing through time. For birds there is a special opportunity to undertake studies of range changes, making use of the data collected by the First and Second Southern African Bird Atlas …

UTR prediction programs for trypanosoma brucei
… UTRs. These regions tend to exhibit less cross-species conservation than do coding sequences. There are many software packages available today for use in determining UTRs, most of which are only available for use by not-for-profit organizations such as universities. Such programs include BLAST …

Bull trout (Salvelinus confluentus) population structure and extent of hybridization with brook trout (S. fontinalis) across Alberta's Eastern Slopes
… fundamental in advancing our understanding of species conservation. Bull trout (Salvelinus confluentus), a charr native to northwestern North America, face population declines and require protection to ensure their persistence and survival. In my thesis, I used genetic loci known as Single …

Great white sharks Carcharodon carcharias in Gansbaai, South Africa : environmental influences and changes over time, 2007-2011
… pre-emptive measure was intended to protect this species from increasing fishing pressure to allow researchers to gather information of this shark’s distribution, basic life history traits, breeding behaviour, and habitat use. Following this, the species conservation status was placed on CITES …

Habitat Modeling of Three Endemic Crayfish Species in the Black River Drainage of Missouri and Arkansas: Factors Affecting Distribution and Abundance
… and anthropogenic factors influence these three species across multiple spatial scales. Local and landscape data were used in decision tree analyses (CART) to determine their influence effect on presence/absence and density of the three species. Predictive models were validated using k-fold cross …
