dc.description.abstract1.Identifying which species are being negatively impacted by climate change and the mechanisms driving their decline is essential to effectively protect biodiversity. 2.Coenonympha pamphilus is a common and generalist butterfly, widely distributed throughout the Western Palearctic, being multivoltine in southern Europe. Previous studies indicate that it will not be substantially affected by climate change; however, it has seemingly disappeared from the southeast of the Iberian Peninsula in the last decades. 3. Here, we aim to determine if it has effectively disappeared from this area, as well as identify the environmental conditions limiting its distribution and the potential causes behind this a priori local extinction. 4.We downloaded all the occurrence records of C. pamphilus and analysed their spatial and temporal trends. To identify the climatic variables driving the distribution of this butterfly in the Iberian Peninsula, we performed an ensemble species distribution model (SDM), combining 600 individual models produced with 6 algorithms. 5.We confirmed that C. pamphilus has not been observed in the southeast of the Iberian Peninsula since 2008. Aridity was the main factor limiting the distribution of C. pamphilus in our ensemble SDM, with areas with high aridity being unsuitable for this species. 6. We hypothesise that multivoltinism is the mechanism driving this local extirpation, as high aridity is causing host plants (Poaceae) to wither prematurely, precluding the development of the second and/or third generations of the butterfly. Even though generalist species are theoretically more resilient to climate change, other traits such as multivoltinism may increase their vulnerability and need to be further investigated.
dc.description.abstract1.Para proteger eficazmente la biodiversidad es esencial identificar qué especies están siendo afectadas negativamente por el cambio climático y los mecanismos que impulsan su declive. 2.Coenonympha pamphilus, es una mariposa diurna común y generalista, ampliamente distribuida por el Paleártico occidental, siendo polivoltina en el sur de Europa. Estudios previos indican que no se verá sustancialmente afectada por el cambio climático. Sin embargo, parece haber desaparecido del sureste de la Península Ibérica. 3. Aquí, pretendemos determinar si efectivamente ha desaparecido de esta zona, así como identificar las condiciones ambientales que limitan su distribucion y las posi- bles causas que están detrás de esta a priori extincion local. 4. Descargamos todos los registros de presencia de C. pamphilus y analizamos sus tendencias espaciales y temporales. Para identificar las variables climáticas que impulsan la distribucion de esta mariposa en la Península Ibérica, realizamos un modelo de distribucion de especies (SDM), combinando 600 modelos individuales produci- dos con 6 algoritmos. 5. Confirmamos que C. pamphilus no se ha observado en el sureste de la Península Ibérica desde 2008. La aridez fue el principal factor que limito su distribuci on en nuestro SDM, siendo las zonas con alta aridez poco adecuadas para esta especie. 6. Nuestra hipotesis es que el polivoltinismo es el mecanismo que impulsa esta extincion local, ya que la elevada aridez está provocando el agostamiento prema- turo de las plantas hospedadoras (Poaceae), impidiendo el desarrollo de la segunda y/o tercera generacion de la mariposa. Aunque las especies generalistas son teoricamente más resistentes al cambio climático, otros rasgos como el polivolti- nismo pueden aumentar su vulnerabilidad y deben ser investigados más a fondo.
