Interactions in shrubsteppes: Implications for the maintenance of a threatened bird

The interactions between ecosystem components and their implications on birds have been poorly studied, especially in shrubsteppes. In this work, we evaluate the interactions between vegetation structure, arthropods availability and the use of space by the Dupont's lark (Chersophilus duponti) i...

description The interactions between ecosystem components and their implications on birds have been poorly studied, especially in shrubsteppes. In this work, we evaluate the interactions between vegetation structure, arthropods availability and the use of space by the Dupont's lark (Chersophilus duponti) in important areas for the species in the Iberian Peninsula. To that end, between 20152018 springs, bird censuses and microhabitat samples were carried out in suitable areas for the species, which should be taken as a reference for habitat restoration tasks. The intensity of space use by the species was calculated by a kernel density function, which defines the probability of finding a territory from the spatial pattern of observations.
