The process of conserving biodiversity: From planning to evaluating conservation actions on private land in the Cape Lowlands, South Africa
Conservation can be conceptualised as a process of linked phases that contribute to bringing about effective biodiversity protection: (i) a conservation assessment that identifies spatially explicit conservation priorities to provide strategic guidance on where best to invest conservation …

Operations and techniques for energy conservation by local governments
… often finding themselves required to make energy conservation decisions with a significant amount of experience in management procedures, but little or no experience in evaluating technical energy conservation data. This document was written in an attempt to provide local government administrators …

Using simulations to predict the genetic connectivity of the Mojave desert tortoise
… species is critical for developing appropriate conservation actions, but the effects of habitat fragmentation are often delayed, making it difficult to assess the impacts of recent landscape change. One tool often used to predict the impacts of fragmentation are agent-based models, which …

Conservation Awareness and Public Knowledge of the Endangered Southern Resident Killer Whales (Orcinus orca) on Vancouver Island, Canada
… study examined public knowledge, awareness, and conservation actions regarding SRKWs among 483 residents of Vancouver Island, Canada. Guided by Value‑Belief‑Norm and Place Attachment frameworks, it was predicted that length of residence would be positively associated with SRKW knowledge and …

Applications of the IUCN Red List in evaluating global extinction risk of timber tree species.
… for rapid species assessment in order to inform conservation actions. However, the use of ‘big data’ is coming to the fore in ecological research, and offers a valuable chance to meet international assessment targets such as those of The Global Strategy for Plant Conservation (GSPC), which call …

Reassessment of the extinction risk of the Neotropical freshwater crabs of the family Pseudothelphusidae
… 48 genera and 289 species. The 2008 IUCN global conservation assessment found 15.5% of the Pseudothelphusidae to be threatened with extinction and projected that in the worst-case scenario (if all of the Data Deficient species turned out to be threatened), the number of threatened species would …

Understanding and improving the cost-effectiveness of biodiversity conservation
Biodiversity conservation is currently facing extraordinary challenges but remains severely limited by funding. Thus, the importance of cost-effective conservation is being increasingly realised – requiring information on both the effects and costs of actions taken to conserve biodiversity. Yet, …

Wintering Reddish Egret (Egretta Rufescens) Foraging Response To Environmental Variability On The Southern Texas Gulf Coast
… winter foraging preferences and may help inform conservation actions including suitable habitat identification and protection in the future.

Populations studies on two endemic taxa of southwestern Sardinia: Dianthus morisianus Vals. (Caryophyllaceae) and Anchusa littorea Moris (Boraginaceae)
… making it difficult to identify and recommend conservation actions. The thesis provides a detailed investigation of the population ecology of the existing populations of the two species with the aim of identifying the constraints on their viability. Specifically, the aims of the present study …

Ecosystem Transformation Across a Changing Social Landscape: Landowner Perceptions and Responses to Woody Plant Encroachment
… Great Plains of the United States where the actions of private landowners are integral to sustaining grasslands. Increased diversity in landowners’ motivations for owning land have shifted the social landscape of rural areas necessitating a better understanding of landowners’ perspectives …

EVALUATING IMPACT ASSESSMENT IN NON-PROFIT CONSERVATION PROJECTS
Conservation organisations strive for positive impacts from their projects, often working in difficult conditions, with limited resources. In many cases conservation projects have successfully protected species and landscapes. However, sometimes things go wrong. Nowhere is this more obvious than in …

Cultural Built Heritage's Tangible and Intangible Dimensions and Digitalization Challenges
… ‘digital revolution’ in the field of the conservation of Cultural Built Heritage. Within this framework, this study analyzes how the dynamic relationship between tangible and intangible heritage strongly affects the understanding of a site as cultural heritage. This relationship influences …

Modelling the current and potential distribution of woody plants, with special emphasis on the importance of spatial scale and environmental factors
… of invasive species are required for management, conservation actions, and legislation. Using predictive geographical modelling, this thesis assesses the role of spatial scale in understanding the determinants of species distribution, modelling invasion spread, and taking conservation decisions. …

ECO-LENS Addressing Urban Biodiversity with Machine Learning
… key ecosystem services is crucial for targeted conservation actions, particularly in urban areas. Urban regions have doubled in size since 1992, and compared to 2020, they are expected to expand by 30% to 180% by 2100. Most of this growth will occur in the global south, in regions rich in …

Abundance Trends and Drivers of Change in Freshwater Fish Communities of the New River Basin
… little consideration or protection under current conservation law. I suggest potential avenues for improvement of conservation actions to help preserve these unique species and communities based on their responses to various land-use and non-native species stressors. My study framework should be …

CHROMOSOME-LEVEL DE NOVO GENOME ASSEMBLIES OF AVIAN SPECIES AND THEIR RELEVANCE FOR COMPARATIVE GENOMICS, PANGENOMICS, POPULATION GENOMICS AND SPECIES CONSERVATION.
… collapse of biodiversity. The establishment of conservation initiatives is now more crucial than ever and the genetic management of threatened species is currently gaining critical significance. Previous genetic studies have been limited by the lack of complete reference genomes, thus having to …

POPULATION GENOMICS, DISTRIBUTION AND REPRODUCTIVE ECOLOGY OF AN ITALIAN STENO-ENDEMIC CHASMOPHYTE, CAMPANULA RAINERI
… rarity and predict the possibilities for future conservation of a model chasmophyte species, Campanula raineri Perp. (Campanulaceae), a tetraploid steno-endemic of the Italian Prealps, by addressing the following hypotheses: 1) Polyploidy (chromosome set duplication) is a principle driver for the …

Bayesian approach for modeling zero-inflated plant percent covers using spatial left-censored beta regression
… responses to climate change and further to aid conservation decisions. Typical challenge with ecological data is the large number of zeros: most of the time species are not observed at the sampling location. Zeros can be thought to arise from ecological reasons or due to randomness. This problem …
