Prey Selection of Scandinavian Wolves: Single Large or Several Small?
Research on large predator-prey interactions are often limited to the predators' primary prey, with the potential for prey switching in systems with multiple ungulate species rarely investigated. We evaluated wolf (Canis lupus) prey selection at two different spatial scales, i.e., inter- and intra-territorial, using data from 409 ungulate wolf-kills in an expanding wolf population in Scandinavi...
متن کاملEstimating parameters of neutral communities: from one single large to several small samples.
The neutral theory of S. P. Hubbell postulates a two-scale hierarchical framework consisting of a metacommunity following the speciation-drift equilibrium characterized by the "biodiversity number" theta, and local communities following the migration-drift equilibrium characterized by the "migration rate" m (or the "fundamental dispersal number" I). While Etienne's sampling formula allows simul...
متن کاملRecolonizing gray wolves increase parasite infection risk in their prey
The recent recolonization of Central Europe by the European gray wolf (Canis lupus) provides an opportunity to study the dynamics of parasite transmission for cases when a definitive host returns after a phase of local extinction. We investigated whether a newly established wolf population increased the prevalence of those parasites in ungulate intermediate hosts representing wolf prey, whether...
متن کاملShifting prey selection generates contrasting herbivore dynamics within a large-mammal predator-prey web.
Shifting prey selection has been identified as a mechanism potentially regulating predator-prey interactions, but it may also lead to different outcomes, especially in more complex systems with multiple prey species available. We assessed changing prey selection by lions, the major predator for 12 large herbivore species in South Africa's Kruger National Park. The database was provided by recor...
متن کاملDifferences in Characteristics of the ERP System Selection Process between Small or Medium and Large Organizations
In this paper we detail the results from an empirical study concerning differences in characteristics of the ERP system selection process between small or medium and large sized organizations. In particular we address the fields of software packages considered and chosen, the weights assigned to different selection criteria, the persons involved in this process, the methods employed and impleme...
