However, the average decline after Filomena was 66.5% for seven populations monitored both in the year before and after Filomena, i.e. According to the results obtained, during the control period, between 20, the species suffered an overall annual decline of 19.4% for the 14 populations sampled. The researchers have analyzed the changes in the abundance of the Dupont's lark before and after Storm Filomena in 14 populations in the provinces of Soria, Lleida, Murcia, Burgos, Segovia and Valencia. In this work, they used Dupont's larks as a study model because it is a species with annual monitoring in several localities and because it is a resident, threatened species with a highly specialized habitat selection. ![]() ![]() ![]() In this sense, scientists must be aware that the frequency and intensity of these extreme weather events may increase in many regions in the coming decades due to climate change. As Cristian PĂ©rez-Granados, lead author of the article and distinguished researcher Beatriz Galindo of the University of Alicante (UA) Department of Ecology, points out, the aim of this study has been to expand scientific knowledge on the impact of extreme weather events, such as the one experienced last January 2021 in Spain with Storm Filomena, on the population dynamics of endangered fauna, since such events can represent a general threat to diversity.
