The breeding biology and nest-site selection of American crows (Corvus brachrhynchos) was studied in 2 areas of aspen parkland habitat in Saskatchewan in 1987 and 1988.<br>Overall, density of nests at St. Denis averaged twice that found at Elstow and clutches were initiated earlier at St. Denis than at Elstow. Clutch size and hatching success did not differ between years or areas, but in 1987, nests at St. Denis produced nearly twice as many young as at Elstow.<br>Crows nested in willow, aspen, and other trees. Nest trees were larger than randomly-selected trees in both years and areas. At St.

Abstract:

Abstract Rare and elusive species are difficult to study, because they are usually secretive, solitary, occur at low densities and have large home ranges. Wolverines (Gulo gulo) can both hunt and scavenge for food. In Fennoscandia, wolverines co-exist with either wild or semi-domesticated reindeer, which constitute their most important winter food. Approximately half of the 180–220 Finnish wolverines are found in northern Finland within the reindeer management area. However, the other half of the population is distributed in eastern and central Finland, and the ecology of wolverines especially

Abstract:

This thesis demonstrates how tidal changes in the availability of intertidal zone habitats can affect the distribution and behaviour of juvenile pollock (Pollachius virens). Schools of pollock moved from the subtidal zone to the open habitat in the intertidal zone. On rising tides, pollock switched from the open habitat at low tidal stages to the dense algal habitat at high tidal stages. On falling tides, pollock rapidly schooled downshore in the open habitat. Pollock were rarely solitary in the open habitat and usually formed large schools. In the algal habitats, pollock were usually disperse

In one of the first reintroductions of a semi-wild population of bison (Bison bison) east of the Mississippi River, The Nature Conservancy reintroduced bison to the Nachusa Grasslands in northern Illinois in October 2014.

My objective was to quantify bison habitat selection during 2014-16 to address literature gaps while investigating seasonal and annual changes.

Mallard broods' habitat use differed from 1988 to 1989 (from emergent to shrub-emergent areas) when average water levels were higher.

The habitat selection of 22 moose, 8 males and 14 females, in southwestern Sweden was studied from February 2002 until December 2005.

Successful forest management requires an understanding of the habitat requirements of individual species at multiple spatial scales. The cerulean warbler (Dendroica cerulea) is a neotropical migratory songbird that has recently gained widespread attention as a species of conservation and management concern. It breeds in mature, deciduous forests of eastern North America and has experienced precipitous range-wide declines over the last 40 years. Although Kentucky likely supports one of the largest breeding populations of the species, no information exists on cerulean warbler habitat selection w

I used a non-mapping technique and line transects to determine availability of vegetation associations and slope classes, and species composition, respectively.

The UK population of hedgehogs (Erinaceus europaeus) has halved in rural areas between 2005 and 2015, and hedgehogs select urban areas over arable land.

I investigated the reasons for hedgehog avoidance of arable land by measuring hedgehog habitat use, ranging behaviour, daily energy expenditure (DEE) and diet along a gradient of habitats from rural villages to arable farmland, under varying predation t

Abstract:

Coexistence is common in nature. Two fundamental conditions must meet for competitive species to coexist. First, at least one environmental dimension must be heterogeneous enough for various species to exploit it. Second, these species must show a certain degree of intrinsic potential to differentiate along this dimension. Organisms living and partitioning in mosaic habitats are often destined to coexist. Here, I propose that habitat selection is one of the major mechanisms promoting coexistence of desert scorpions. I tested this mechanism in a three-species community (Centruroides exilicauda,

Abstract:

Variations in species occurrence and distribution across the landscape over time provide fundamental information concerning population dynamics. How this relates to habitat characteristics at multiple scales can elucidate the process of habitat selection. I evaluated these processes for a montane fir (Abies) forest specialist, Bicknell’s Thrush (Catharus bicknelli) in Vermont. This species is threatened by a suite of anthropogenic disturbances on its breeding grounds and quantifying the effects of environmental change at the population level for this songbird has not been addressed.

Abstract:

Habitat selection by breeding black ducks (Anas rubripes) was studied in Antigonish County, Nova Scotia during April-September 1990 and 1991.<br>Black duck pairs selected deciduous shrub ponds and sparsely vegetated ponds and avoided estuarine marsh and large lake habitat. Hens with broods preferred the deciduous shrub habitat while they avoided large lakes.<br>Black duck pairs appeared to use the distance to a brood-rearing pond as a cue in site selection. The closer a pond was to a suitable rearing pond the more likely it was occupied by a pair, regardless of food or cover resource availabil

Abstract:

With the advent of global position system (GPS) collar technology, we have developed a much greater understanding of the temporal and spatial distribution of livestock and their associated grazing patterns. While significant research using GPS collars has been reported for cattle, little research is available describing collar use in understanding the behavior of domestic sheep. The purpose of our research was to evaluate the energy requirements of sheep with the use of GPS collars. To accomplish this, we adapted a low-cost i-gotU GPS tracking device that is typically designed for cattle and m
