Comparing Landscape Suitability And Permeability With And Without Migration Data: Theinfluence Of Species Movement Behavior, Azita Rezvani, Shima Malakoutikhah, Sima Fakheran, Alireza Soffianian, Mahmoud-Reza Hemami, Josef Senn

Turkish Journal of Zoology

Maintaining landscape connectivity through identifying movement corridors is the most recommended conservation strategy to reduce the negative impacts of habitat loss and isolation. The basis of most connectivity modelling approaches for modelling corridors is that species choose movement pathways based on the same criteria they used to choose habitats. However, species behave differently in using landscape elements for moving than for selecting habitat. In other words, suitability of a given landscape feature may differ between moving and habitat use stages. In this study, we evaluated how the availability of migration occurrence points for wild sheep (Ovis orientalis) could affect the …
