A survey of the Blanford's fox was established in Jabal Masuda (Southern Jordan), to increase the knowledge of its density. Live-trapping method was used and capture mark-recapture technique was applied. We captured a total of 27 specimens including nine re-captured specimens. Density was determined using two methods: the Bondrup-Nielsen formula which identified 8.5 individuals per km2, and the ArcGIS tools which showed values, between 0.177 to 9 individuals per km2. This paper is the first to give measured information on the Blanford's fox density in Jordan. As well, it showed that ArcGIS 9.3 Spatial Analyst Extension is an effective tool in establishing information on density in large spatial areas. The information provided could serve as a base for future monitoring of the Blanford's fox's range of occurrence. © 2013 Senckenberg Gesellschaft für Naturforschung.

Breeding territories of Mourning Wheatear Oenanthe lugens were investigated in three study areas in Jordan to describe and explain variation in territory size along an aridity gradient. In moderately productive semi-deserts, Mourning Wheatears defended small territories (averages for two different areas 3.0 ha and 5.9 ha) that were arranged as relatively dense neighbourhood clusters, while in extremely arid deserts, territories were significantly larger (average 22.8 ha) and arranged in very loose clusters. Contender pressure and probably vegetation cover (as cue of sustained prey availability) played a dual role in determining territory sizes. The relative role of prey availability as proximate factor increased with aridity due to low contender pressure in extremely arid deserts. © 2010 Elsevier Ltd.
