Streszczenie:

The aim in this study was to develop a model for the probability of finding active golden eagle nests during their breeding season. It was done by using environmental variables derived from expert models which were tested against empirical data. This resulted in a habitat suitability index (HSI), which in this case is assumed to indicate the probability of active nests of golden eagles. The study was conducted together with the County Administrative Board of Västernorrland with the purpose to improve golden eagle’s ecological status.To develop the model, different combinations of several expla

Efforts to reintroduce and maintain populations of pronghorn (Antilocapra americana) to the California Central Valley, specifically the Carrizo Plain National Monument (CPNM) and the Mojave Desert (Antelope Valley) portion of Tejon Ranch, have largely been unsuccessful due to dwindling numbers of translocated animals. The objective of this study was to improve upon previous models for the CPNM using aerial survey data and then apply the model to the Tejon Ranch. Aerial survey data collected from 2000-2010 on the CPNM was used to establish “use” and “non-use” areas in the model. Model variables

With exploding human populations and landscapes that are changing, an increasing number of wildlife species are brought to the brink of extinction. In Canada, the eastern hog-nosed snake, 'Heterodon platirhinos', is found in a limited portion of southern Ontario. Designated as threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), this reptile has been losing its habitat at an alarming rate. Due to the increase in development of southern Ontario, it is crucial to document what limits the snake’s habitat to direct conservation efforts better, for the long-term sur

It is widely known that the world is losing biodiversity and primarily it is thought to be caused by anthropogenic activities. Many of these activities have been identified. However, we still lack a clear understanding of the causal relationships between human activities and the pressures they place on the environment and biodiversity. We need to know how ecosystems and individual species respond to changes in human activities and therefore how best to moderate our actions and reduce the rate of loss of biodiversity. One of the ways to detect these changes is to use indicators of e

The Florida Sandhill Crane (Grus canadensis pratensis) is a state threatened endemic subspecies of the Sandhill Crane (Nesbitt & Tacha, 1997). With a population that was estimated at a maximum of 5,000 individuals in 2003 (Nesbitt & Hatchitt, 2008), it is imperative to identify potentially viable habitats, as Florida is rapidly developing. This research develops a Habitat Suitability Index model to determine unsuitable to optimally suitable habitat locations throughout west-central Florida. To do so, six suitability variables based on the crane’s life history were evaluated: Potential nesting

Fisheries combined with climate change may cause the redistribution of marine species commercially exploited by fisheries and these changes can cause considerable socio-economic impacts.

碩士<br>國立中興大學<br>森林學系<br>90<br>Abstract Species spatial distribution, species abundance and habitat suitable index are important information for managing wildlife populations and conserving biodiversity. Therefore, the techniques for evaluating wildlife habitats quantitatively are important tools for Ecosystem Management (EM). the main purpose of this study is to integrate the digital photogrammetry and geographic information system(GIS) technology to present the land-use pattern, digital s

Aquaculture is one of the fastest growing activities worldwide. In 2006, it already accounted for around 40% of total fish consumption, and since 2012, aquaculture is the main source of marine food supplies. However, this strong and fast development of the sector tends to be reflected in significant environmental impacts and new challenges in the management and planning of the coastal areas. In this context, this work intends to contribute to the sustainability of the sector, by identifying preferential locations to ensure aquaculture expansion and proper operation in a sustainable manner

Invasive alien species (IAS) pose a serious threat to ecosystems and societies worldwide. Local ecological knowledge (LEK) is increasingly valued as a means of understanding environmental issues; however, its application in the context of IAS research has been limited. The overall objective of this study was to document the LEK of farmers and Weed Supervisors to gain insight into a recent IAS, Odontites serotina. I conducted semi-structured interviews with farmers and Weed Supervisors with O. serotina management experience. Results indicated that the socio-economic impacts for farmer

Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial Technologies<br>The prediction of species' distribution is fundamental to many applications in ecology, wildlife conservation and the science of evolution. Variations in the abundance within a species' geographic range provide the connection between the disciplines of ecology, geostatistics and biogeography. Species predictive modelling is quite intricate considering the spatial and aspatial variables that both play interactive roles in predicting a species' occurrence. Like many

Seasonal habitat suitability models for Roosevelt elk, Cervus elaphus roosevelti, (Brunt 1991) were tested using two distinctly different study areas on northern Vancouver Island, British Columbia. Locations for 5 radio-collared elk, obtained approximately twice per week by telemetry from May 1992 to August 1993, were used to test the models. I used the adaptive kernel method to estimate seasonal home ranges from each elk's locations. Habitat suitability values for summer, mild winter, and severe winter were calculated across each study area on a geographic information system (GIS), usi

For the west coast of North America, from northern California to southern Washington, a habitat suitability prediction framework was developed to support wave energy device siting. Concern that wave energy devices may impact the seafloor and benthos has renewed research interest in the distribution of marine benthic invertebrates and factors influencing their distribution. A Bayesian belief network approach was employed for learning species-habitat associations for Rhabdus rectius, a tusk-shaped marine infaunal Mollusk. Environmental variables describing surficial geology and water depth were

The work of this thesis aims to highlight the contribution that suitability models can give to global scale conservation biology. Four main themes will be approached: Opportunity offered by model improvements; Information added to analyses on current protection status; contribution offered to priority setting; information added to long term efficiency in conservation plans
