This paper presents modeling approaches for wildlife and species conservation with a special emphasis on large mammals in a developing country setting. In such countries there are frequently conflicts over land use and species conservation, and institutions for managing conflicts are often weak...

A four-stage model (calves, yearlings, adult female and adult male) of the Scandinavian moose (Alces alces) is formulated. Fecundity is density dependent while mortality is density independent. The paper aims to demonstrate the economic content of such a wildlife model and how this content may...

A static bioeconomic model of a marine reserve allowing asymmetric density dependent migration between the reserve and the fishable area is introduced. This opens for habitat or ecosystem differences allowing different fish densities within and outside a reserve, not described in earlier...

This study develops a model for wildlife migrating seasonally between a conservation area and a neighbouring area. When being outside the conservation area, harvesting takes place by a group of small-scale farmers. The local people have two motives for harvesting; to get rid of ‘problem’...

Total Allowable Catch (TAC) regulating schemes have been introduced in most fisheries. TAC distribution following the Proportional Rule, based on historical catches, implies that harvesters or vessel groups which have captured more in the past and contributed to overfishing are getting larger...
