Relationships between climate variables, seed production and reproduction of the Edible Dormouse (Glis glis) in mixed oak forests of the Iberian Peninsula

The Edible Dormouse ( Glis glis ) is a small arboreal mammal that lives in deciduous forests much of Europe, the Iberian Peninsula being one southern limits its distribution. Some studies have shown this species uses strategy anticipatory reproduction, which means it adapts reproductive effort to seed production, such as beech mast and acorns, varies greatly from year year. anticipates future availability coming autumn modulates effort, acorns are crucial resource for young survive their first hibernation. This work aims determine correlations between annual variations climate effect on reproduction using 9 years data (2012–2020) two natural parks Catalonia (Montseny Montnegre-Corredor). These located at southernmost limit distribution Peninsula. results show productivity Beech trees Fagus sylvatica conditioned by local meteorological conditions pollen availability, acorn production oak Quercus sp. also affected conditions, but not availability. Additionally, breeding Montseny has high synchrony with presence seeds increases number offspring per female. encourage us conduct predict how populations will be impacted change.
