Ecological Infrastructure: A Framework for Planning and Design: "Addressing Landscape Connectivity and Wildlife Resources for Interstate Highway Systems"
… a dominant force shaping the modern American landscape. An unrivaled interstate highway system connects major metropolitan areas and is the basis of our transportation infrastructure. Unfortunately, many roadways were not planned or designed with wildlife in mind. As long linear features in …

Spatio-Temporal Connectivity in Dynamic Tropical Fragmented Landscapes
… that result in highly dynamic forested landscapes. These dynamical landscapes, when subjected to the current scenario of intense global change, poses particular challenges for biodiversity conservation in human-modified landscapes. This thesis provides insights towards (i) the …

Population Dynamics and Connectivity Patterns of Adfluvial and Stream-Resident Cutthroat Trout
… population dynamics, life history variation, and connectivity patterns of threatened cutthroat trout (O. clarkii spp.) is critical for effective management and restoration. The Lahontan cutthroat trout (O. c. henshawi; LCT) is classified as threatened under the Endangered Species Act due to …

Mapping Connectivity: Integrating Ecological Landscape Analysis into Urban Planning in the City of Nanaimo
… are critical for maintaining biodiversity, yet connectivity planning must balance ecological sustainability with urban growth and socio-economic considerations. This study had two main objectives: (1) identify from the literature which landscape, ecological, land use, and infrastructure …

Environmental, spatial and temporal drivers of plant community composition in British forest habitat
… for many rare plant species in human-modified landscapes. It is however, threatened by global change drivers such as deforestation and the associated fragmentation of remaining habitat areas, along with increased disturbance and exposure to nutrient inputs from surrounding intensive …

Predicting biodiversity loss in insular neotropical forest habitat patches
… increasing their protection, and enhancing connectivity of surrounding habitats becomes clearly important. For future Amazonian dams, it is recommended that engineers should consider the overall topography of planned reservoirs to maximise landscape connectivity and/or reject plans targeting …

Weaving through the matrix: investigating the influence of urban land use on weaver bird movements into and out of Cape Town wetlands
… important implications for maintaining current landscape connectivity. Habitat isolation, resulting from further habitat removal or destruction, could be expected to reduce movements of weavers, and potentially other species, among patches of favourable habitat. Weavers are robust, vagile birds …

Effectiveness of UK Legislation and Management in Producing Nature Conservation Outcomes: a Case Study of the Purbeck Heaths
… and increase overall biodiversity through landscape-scale management. The Purbeck Heath covers designated protected areas such as Sites of Special Scientific Interest (SSSI), Special Areas of Conservation (SAC), Special Protected Areas (SPA), and Ramsar Sites. This study investigated …

Ecology and Structure of Black Bear (Ursus americanus) Populations in the Interior Highlands of Arkansas
… into and out of populations, a process called connectivity, fundamentally shape wildlife distribution and abundance across the landscape. Connectivity determines taxonomic distinctiveness, colonization of new sites, and persistence of both local populations and metapopulations of linked …

Landscape Ecology of Chronic Wasting Disease in Virginia, USA
… predict their occurrence and spread across landscapes. Chronic wasting disease (CWD) is a neurodegenerative disease in the deer family Cervidae caused by a prion, a pathogenic and misfolded variant of a naturally occurring protein. Managing and controlling CWD is imperative for conservation …

State-wide assessment of status, predicted distribution, and landscape-level habitat suitability of amphibians and reptiles in Montana
… and areas that are critical for maintaining landscape connectivity.</p> In conjunction with field inventories, a state-wide assessment of the distribution of the pathogenic chytrid fungus (<i>Batrachochytrium dendrobatidis</i>) (Bd) was undertaken using PCR-based detection in skin swabs or …

Puma Dispersal Ecology in the Central Rocky Mountains
… gap exists in our knowledge of the influence landscape heterogeneity has on dispersal and its consequences. We examined landscape effects on dispersal and its consequences for puma (Puma concolor) populations using data from three separate populations in the Central Rocky Mountains including …

Determining habitat and biotic factors driving puma (<i>Puma concolor</i>) space use and underlying dynamic processes (colonization and extinction) over 20 years in protected and private areas throughout Belize, Central America
… could be targets for protection to preserve landscape connectivity. Additionally, due to high occupancy and colonization across varying habitat and biotic factors the jaguar is likely an effective umbrella species for puma space use, however more analysis on other species is needed to ensure …
