Population ecology is concerned with measuring changes in population size and composition, and identifying the causes of these fluctuations. Important driving variables include animal body size and growth rate, and their relationship to reproduction and m... see more

Since the mid 1980's, the Aishihik herd of woodland caribou (Rangifer tarandus caribou) declined from approximately 1500 to 583 animals. During the same period a nearby herd, the Wolf Lake Herd increased from approximately 664 to 1249 animals. This paper ... see more

This paper is a review of the ecology of two caribou populations inhabiting predator-free northern islands, Coats and Southampton Island. Findings are analyzed in light of the hypothesis that in absence of prédation or high human harvest, food competition... see more

Bergerud has discussed how major differences in caribou density across North America appear to be related to the impact of wolf (Canis lupus) predation, and the strategies used by caribou to avoid wolves. Caribou living in areas without wolves usually occ... see more

AbstractHaworthia koelmaniorum Oberm. & D.S. Hardy var. mcmurtryi (C.L. Scott) M.B. Bayer is an endemic plant restricted to the high-lying areas of Mpumalanga Province in South Africa. There is a serious lack of information on this species; it was known ... see more

In this study, the interactions among populations and the effects on founding rates are examined within the context of organizational ecology theory. Two populations, bank intermediary institutions and non-bank intermediary institutions, which perform the... see more

Wild reindeer in Norway, presently (winter 2005-06) numbering some 25 000 animals, are found in 23 more or less separated areas in the mountainous southern part of the country (see map in appendix). All herds are hunted and management is organized in clos... see more

Use of the subspecies as the basic unit in the conservation of endangered caribou (Rangifer tarandus) would produce a “melting pot” end-product that would mask important genotypic, phenotypic, ecological, and behavioral variations found below the level of... see more

The population differences in ecology and behaviour of reindeer (Rangifer tarandus spp.) is closely paralleled by the characteristic features of reindeer husbandry which reveals the close relationship between behaviour and husbandry. The western portion o... see more
