Diet and co-ecology of Pleistocene short-faced bears and brown bears in eastern Beringia
This paper presents stable carbon and nitrogen isotope data obtained from the fossil bone collagen of late Pleistocene short-faced bears and brown bears, and bone collagen from modern brown bears in eastern Beringia. The data elucidate many
important aspects of these bears'diets and can be used to test the potential for competive interactions. The A. also summarizes a model of short-faced bear foraging behavior that is the most parsimonious integration of the isotope data and the morphological
A geographical approach to William Faulkner's the Bear
Il reste peu de choses du paysage du Mississipi qu'avait décrit W. Faulkner dans The Bear, les changements qu'il avait imaginés puis dénoncés se sont effectivement produits.
Small monthly water bearing values of the streams of the Czech Socialist Republic
The continous duration of small monthly water bearing values is analysed in the four year periods in plains, hilly lands and lower highlands. They are connected with lack of precipitation especially in the autumn and winter periods. Owing
Soil-landscape relationships at the lower reaches of a watershed at Bear Creek near Oak Ridge, Tennessee
This study examines the effects of slope and geomorphic processes, human impacts, and particular characteristics of soils and saprolite that may effect drainage and water movement in the wetlands and adjacent landscapes in a watershed at Bear Creek
The A. argues that Yu. P. Seliverstov made a mistake when relating the Lower Cretaceous surface in Kazakhstan to the Gondvana surface in Africa : in fact it corresponds to the African surface which bears a thick lateritic crust. The latter is also
erroneously equated by Seliverstov with the Eocene surface in Kazakhstan which bears a thick lateric crust. The latter is also erroneously equated by Seliverstov with the Eocene surface in Kazakhstan which bears only siliceous crust of weathering. - (L'Ed.).
Oil and gas infrastructure and the spatial pattern of grizzly bear habitat selection in Alberta, Canada
This article examines oil and gas infrastructure and the spatial pattern of grizzly bear habitat selection in the Kakwa region of Alberta, Canada. The results indicate that bears are generally observed closer to oil and gas features during spring
. Adult males are farther than expected to all features during the summer season. During fall, adult females show avoidance of all oil and gas features during the day, but were closer at night. Active well sites are avoided by all bears in the fall
Pleistocene stratigraphy, paleopedology, and paleoecology of a multiple till sequence exposed on the Little Bear River, Western District of Mackenzie, N.W.T., Canada
La coupe de Little Bear River est localisée dans une zone de transition entre la plaine du Mackenzie et les Canyons Ranges des monts Mackenzie. L'extension maximale de l'inlandsis laurentidien y chevauche l'extension plus ancienne des glaciers de
