Behavioural Ecology of Lake Trout: From Movement Ecology to Bioenergetics
The movement patterns of most organisms are directed to maximizing the success of habitat exploitation, which can be quantified by examining population-level parameters such as size and age at maturity, and the population bioenergetics. Similarly, the behavioural decisions of organisms are …

A multi-scale study on the movement ecology of Afrotropical waterbirds
… the processes and mechanisms governing animal movement is a fundamental goal in ecology. Processes driving movement can occur across multiple spatiotemporal scales and have important consequences for the structure and dynamics of populations, communities and ecosystems. The study of movement …

Air-breathing and movement ecology of Arapaima sp. in the Amazon
… for seasonally hypoxic waters and directed movements to best utilize habitats as they become available. This study examined the environmental, temporal and body-size influences on air-breathing behavior and movement ecology of Arapaima sp., one of the most economically and ecologically …

Effects of Fertility Control on the Movement Ecology of White-Tailed Deer
… explores the effects of fertility control on the movement ecology of white-tailed deer (Odocoileus virginianus Zimmermann). Deer populations may become abundant in human-dominated landscapes, taking advantage of anthropogenic resources and the lack of natural predators. This abundance poses …

Movement ecology of the bronze whaler shark (carcharhinus brachyurus) in southern Africa
… that alter the abundance, distribution or movements of large sharks can thus have destabilising ecosystem impacts along economically important coastal regions. The bronze whaler shark (Carcharhinus brachyurus) is a vulnerable carcharhinid, with a global distribution, largely restricted to …

Movement Ecology and Conservation of the Migratory Bats Lasiurus cinereus and Lasionycteris noctivagans
… and genetic analyses, I studied patterns of movement and relatedness of two species of migratory tree-roosting bats frequently killed by wind turbines: hoary bats (Lasiurus cinereus) and silver-haired bats (Lasionycteris noctivagans). Using stable isotopes of nitrogen (δ15N), carbon (δ13C), …

Movement Ecology and Trophic Dynamics in the northern Gulf of Mexico: Implications for Fisheries Management
… distribution of fishing effort and the stock’s movement ecology. Fish movement was informed using <em>n</em> = 80 acoustically tagged individuals. Chapter 1 expands upon our understanding of the movement ecology of Southern Flounder and using a novel modeling approach, we evaluate management …

Seasonal habitat and movement ecology of adult brook trout in a northern Michigan headwater stream
… fontinalis</em>) exhibit a wide variety of movement and habitat use strategies. Habitat needs change seasonally and ontogenetically, but the degree to which brook trout move among suitable habitats depends on life history strategy and stability in environmental conditions. This study …

Malleefowl and anthropogenic change: an integrated analysis of population trends, landscape genetics and movement ecology
… trends, investigate landscape genetics, study movement patterns and the influence of habitat variables. These objectives were addressed through a multidisciplinary approach to study discrete Malleefowl populations at study sites located on the Eyre Peninsula in South Australia. To assess …

The movement ecology of common bream Abramis brama in a highly connected wetland using acoustic telemetry.
Evidence increasingly suggests that the movement behaviours of potamodromous fishes can be highly diverse in well-connected systems. Intra-population divergence in spatial and temporal resource-use is an important component of fish distribution patterns and population structure, which can affect …

Using spatial methods to analyse anthropogenic predation risk and movement ecology of white-tailed deer (Odocoileus virginianus)
… populations. This research explores the spatial ecology of hunters and White-tailed deer in the Cross Timbers ecoregion of Oklahoma. Using new statistical methodologies to analyse simultaneous GPS tracking data on deer and hunters to study their spatial interactions. The results show how new …

Movement ecology and fisheries bycatch risk of albatross and large petrel species from Bird Island, South Georgia
Recording animal movements is essential for understanding the distribution of species over time, with far-reaching consequences for fitness, population dynamics and conservation. Oceanic seabirds are some of the most mobile and threatened species on Earth, mainly because of incidental mortality …

Movement ecology and habitat use of Canada geese using major metropolitan areas in the context of human-wildlife conflicts
… to urban gradient of the upper Midwest shape the movement and behavioral ecology of Canada geese, requiring unique life history strategies to maximize survival through-out the annual cycle. Winter is an energetically costly period due to food limitation and increased thermoregulatory costs. Urban …

The genes must flow: using movement ecology to understand connectivity of Mojave desert tortoise (Gopherus agassizii) populations in altered landscapes
… mitigation efforts. Connectivity arises from the movement of individuals within and between populations; understanding the movement ecology of a species can provide crucial information in how to best manage populations to maintain gene flow across a landscape. The Mojave desert tortoise (Gopherus …

Movement ecology of two threatened anadromous species, twaite shad Alosa fallax and sea lamprey Petromyzon marinus, revealed by acoustic telemetry.
… anadromous species. Understanding the movement ecology of anadromous species during all phases of their lifecycle is vital to understand, predict and mitigate the impacts of fragmentation. This is especially crucial for groups such as the Alosinae (shads) and Petromyzontiformes …

Modelling animal movement in heterogeneous environments: from statistical inferential models to individual-based models
Modelling animal movement in heterogeneous environments is challenging because organisms experience a complex suite of internal and external stimuli that operate hierarchically over multiple temporal and spatial scales. A fundamental goal of movement ecology is to relate the behaviour of animals to …

Habitat selection and spatial personalities of Belizean white-tailed deer
Understanding movement ecology – broadly defined as the study of how environmental conditions shape animal movement – can provide inference into the environmental traits required to sustain viable wildlife populations. Therefore, movement models have emerged as important tools for wildlife …
