Current status of the threatened Dupont’s lark Chersophilus duponti in Spain: overestimation, decline, and extinction of local populations
Duponts Lark (Chersophilus duponti) Science Article 2 abstract The European population of Dupont’s lark Chersophilus duponti, restricted to Spanish steppe, was estimated to be 13,000 pairs in c. 50 populations in 1988. There is, however, recent evidence that this number was overestimated because of the previous use of line transects for estimating population sizes. In […]
Habitat-suitability modelling to assess the effects of land-use changes on Dupont’s lark Chersophilus duponti: A case study in the Layna Important Bird Area
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 […]
Two new calls from the Dupont’s Lark Chersophilus duponti and imitations by other alaudids: ecological and monitoring implications
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
Home range, territoriality and habitat selection by the Dupont
Duponts Lark (Chersophilus duponti) Science Article 3 abstract A total of 32 birds were radiotagged (22 males, 4 females and 6 juveniles) and monitored nearly daily from April 1st to September 1st. The following variables were measured (1) home ranges using the Minimum Convex Poligon, MCP, (2) core areas using the kernel 80 % density […]
ENERGY AND WATER BUDGETS OF LARKS IN A LIFE HISTORYPERSPECTIVE: PARENTAL EFFORT VARIES WITH ARIDITY
Bar-tailed Lark (Ammomanes cinctura) Science Article 1 abstract We compared physiological, demographic, and ecological variables of larksto gain insights into life history variation along an aridity gradient, incorporating phylogeneticrelationships in analyses when appropriate. Quantifying field metabolic rate (FMR)and water influx rate (WIR) of parents feeding nestlings as measures of parental effort, wefound that parental FMR […]
