Landscape fragmentation affects wildlife population viability, in part, through the effects it has on individual dispersal. In addition, some forms of human disturbance impinge on dispersal without physically fragmenting habitats. Here, we use the term "landscape resistance" to capture constraints to dispersal that cannot be linked directly to fragmentation. The extent to which landscape resist...

Wolf-prey research has focused on single-prey systems in North America dominated by moose (Alces alces) or white-tailed deer (Odocoileus virginianus). Elk (Cervus elaphus) are social ungulates and the main prey item of wolves {Canis lupus) in Banff National Park (BNP), Alberta. Grouping behaviour may affect the functional response of predators by changing how predators encounter and kill prey. ...

The recent discovery of a lineage of gray wolf in North-East Africa suggests the presence of a cryptic canid on the continent, the African wolf Canis lupus lupaster. We analyzed the mtDNA diversity (cytochrome b and control region) of a series of African Canis including wolf-like animals from North and West Africa. Our objectives were to assess the actual range of C. l. lupaster, to further est...

numbers of persian leopards have considerably decreased in recent years and for this reason it has been categorized as endangered in the iucn classification. habitat destruction is believed to be the main cause of the species population decline. hence, attempts to preserve the remaining habitats of this kind of animal effectively are deemed essential in reversing its downgrading trend. to hit t...

Finland has struggled with formulating and implementing policies regarding the national grey wolf (Canis lupus) population. It seems that after major institutional adjustments undertaken to improve wolf protection, the wolf population has, in fact, decreased. This calls for an explanation. My approach to the question of institutional fit builds upon classical institutional economics and pragmat...
