There is, however, recent evidence that this number was overestimated because of the previous use of line transects for estimating population sizes. In […]

Duponts Lark (Chersophilus duponti) Science Article 1 abstract Habitat-suitability modelling is being increasingly used as a tool for conservation biology. Although studies at large spatial scales are more appropriate for reserve design and management, there is a scarcity of published work on local, high-resolution applications of such models. In this work we develop high-resolution habitat […]

Duponts Lark (Chersophilus duponti) Science Article 4 abstract The Dupont’s Lark Chersophilus duponti isone of the rarest Palearctic passerines, whosedistribution is confined in Europe to the remainingsteppe plateaux and lowlands of the Iberianpeninsula (Cramp, 1998). As a consequenceof recent data that revealed that Spanishpopulations are much smaller than previouslyestimated, the species is currently considered
