|Title: ||The role of habitat connectivity on road mortality of Tawny owls|
|Authors: ||Pereira, Miguel|
|Issue Date: ||Jun-2011|
|Abstract: ||Research of habitat fragmentation has revealed a large number of constraining effects on
species, which represent a central issue for wildlife conservation. In this article we address an
approach based on spatial models of tawny owl Strix aluco. The habitat is assessed in relation to
species density and hotspots of road casualties. The data was collected in two years surveys, in the
montado habitat and casualties along 40 km of the road network. Data was used to generate a
density surface and the identification of casualties‟ hotspots. The density surface and the location of
mortality clusters were used to model a spatial perspective of population likelihood and mortality.
The results reveal evidences of increased habitat fragmentation and casualty occurrence. The results
allow us a vision of transportation infrastructure near future consequences of development and
suggestions for defragmentation actions.|
