Habitat Choice and Spatial Ecology of Nerodia Sipedon, the Northern Water Snake
… telemetry to examine the spatial ecology and habitat choice of Nerodia sipedon in a lentic ecosystem in southwestern Missouri. In late spring of 1998, radio transmitters were implanted into 18 adults, which were located daily. Home range areas and shifts in activity centers were calculated …

Experience With Chemical Cues Influences Subsequent Behavior of Rainbow Darters, Etheostoma Caeruleum
… and heterospecific stimuli influenced habitat choice of darters. Darters were initially exposed to the stimuli in one of the two habitats (woody debris and rocks). The results were: (a) Darters exposed to chemical cues from predators (in both habitats) preferred to occupy the rock …

Habitat Mapping and Predator-Prey Dynamics in Ohio Resevoirs
Mechanisms associated with habitat choice in fish are often unknown, and require exploration of many different abiotic and biotic habitat features. The importance of finding these drivers lies in helping to explain population variation. Saugeye Sander vitreum ¿ X S. canadense ¿ are stocked with …

Variação espacial e temporal na estrutura do habitat e prefência de microhabitat por pequenos mamíferos na Mata Atlântica
Nowadays studies on habitat choice have been worried with scale problems, as spatial as temporal scale. This work was carried out in Guapimirim (22°29'S e 43°00'W), Rio de Janeiro State from February'97 to February'98. The study area is a vicinity of Serra dos Órgãos National Park at Atlantic …

The Effects of USDA Farm-Bill Restoration Programs on Prairie Voles (microtus ochrogaster) in the Barrens Region of Kentucky
… population density, body mass, survival, habitat choice, and home range will be measured to quantify the relative success of small mammals with respect to each plant mixture. Results from this study showed that certain small mammals, particularly prairie voles, were more successful in …

Influence of living and non-living habitat complexity on arthropods in strip-tilled cabbage fields
… abundance of important natural enemy species. Habitats with both later oat kill dates or reduced herbicide intensity contained 1) fewer herbivores with chewing feeding guilds and more specialized diet breadths and, 2) greater abundance of active hunting natural enemies. In 2012, mulch species …

The responses of subtropical nearshore fishes to climate change
… Nearshore ecosystems serve as critical habitat for juvenile fishes (e.g., schoolmaster snapper, yellowfin mojarra) and function as foraging grounds for adults (e.g., bonefish, checkered puffer), yet it is unclear how nearshore fishes will respond to forecasted increases in temperature …

Experimental study of fish response to turbulent flow fields generated by in-stream structures
The influence of hydrodynamics on habitat choice and migration path of fish is of great interest for biologists and engineers, especially when considering the impact of in-stream structures like dams or fish passages during stream restoration projects. Research is needed in both laboratory and …

An experimental assessment of the efficacy of falconry to mitigate human-wildlife conflict: Egyptian Geese Alopochen aegyptiaca at golf courses
… would re-establish a landscape of fear, whereby habitat choice is influenced by the perceived fear of predation, resulting in the local departure of geese to a safer habitat, thereby reducing the population of geese to a tolerable level. Absolute counts of geese and analysis of vigilance levels …

Studies of the Annual Cycle of the Swallow-Tailed Kite (<em>Elanoides forficatus</em>): Migration, Habitat Use, and Parasites
… on Cuba and the Yucatan Peninsula, range-wide habitat associations, and parasites. Because Cuba and the Yucatan Peninsula are situated along the migratory route after a long over-water crossing, they may be potentially important stopover sites. To examine this prediction, 29 satellite-tracked …

The ecology of ray species in an urbanised estuary: Seasonality, habitat use and pollutant exposure in Tauranga Harbour
… about the movement, seasonality, and use of habitats by marine animals is vital for the mitigation of potential anthropogenic impacts. Ray species may be particularly at risk as they regularly inhabit coastal and estuarine waters. In New Zealand to-date, there has been scant research on the …

Going through the motions : the impacts of frequent fires and grazing pressure on reproduction of Montane grassland birds
… horizontal heterogeneity. I also examined micro-habitat choices, the form of natural selection and the adaptiveness of preferences in four coexisting grassland bird species (Yellow-breasted Pipit Hemimacronyx chloris, Grassveld Pipit Anthus cinamomerous, Orange-throated Longclaw Macrony capensis, …

Behavioral type - environment correlations in three-spined stickleback
… and the other between exploratory behavior and habitat type. In the second chapter I test the hypothesis that behavioral type-environment correlations are generated via natural selection. My goal in the third chapter was to compare the predictive power of different factors that might explain why …
