title: Communal nesting in the garden dormouse (Eliomys quercinus).
abstract: Communal nesting has been described in many rodents including some dormouse species. In this study, we report the existence of this reproductive strategy in the garden dormouse Eliomys quercinus. Data was recorded by checking natural nests and nest-boxes from 2003 to 2013 in SE Spain. Pups and adults dormice found in nests were captured and marked. Overall, 198 nests were found: 161 (81.31%) were singular nests and 37 (18.69%) were communal nests. Communal nests were composed by different combinations of one up to three females together with one up to three different size litters. The number of communal nests varied from year to year in accordance with the number of singular nests and no seasonal differences were observed. In at least one case, an adult female and her adult daughter were found sharing the same nest-box. The hypothesis that communal nesting was encouraged by a lack of favourable nesting sites was rejected. Litters protection from predators or conspecifics seems the most likely hypothesis to explain communal nesting in our garden dormouse population.
