dc.description.abstract | [EN] Paradoxically, seedlings of clonal plants are rarely observed in nature, despite many of these species producing large amounts of seeds every fruiting season. Studies about clonal plants’ recruitment strategies are usually based on experiments carried out under controlled conditions (e.g., laboratory) and rarely consider frugivores’ effects. We tested the role of endozoochory in the seedling recruitment in natural conditions of the bilberry Vaccinium myrtillus, a widely distributed clonal species and a key resource in temperate and boreal regions of Eurasia, which has been suggested to recruit at occasional windows of opportunity (unpredictable conditions in which seedling recruitment may occur within conspecific adult stands). We marked brown bear Ursus arctos, mesocarnivore (red foxes Vulpes vulpes and martens Martes spp.) and passerine feces containing bilberry seeds in the Tatra Mountains (Carpathian Mountains, Southern Poland) and followed the fate of the embedded seeds during two years. We detected bilberry germination associated with 100%, 87.5%, and 50% of brown bear, mesocarnivore, and passerine feces, and also in 43.6%, 41.2%, and 23.1% of the control plots located 5, 10, and 30 m away from the bear scats, respectively. In bear scats, investigated in more detail, 15.7% of the seedlings survived at least one year. The largest numbers of seedlings were associated with bear scats (154.4 ± 237.3 seedlings/m2), especially to those defecated upon the soil disturbances these animals create next to their resting sites. Our results demonstrate that endozoochory facilitates repeated bilberry seedling recruitment in nature, suggesting that studies on the reproductive strategies of clonal plants must consider the role of frugivores. Some frugivores’ behaviors, such as the defecation by bears in the vicinity of their resting sites, may in fact be crucial for the reproduction of clonal plants and for the adaptation of these species to the current changing climatic conditions | es_ES |

dc.description.project | This study was supported by the BearConnect project funded by the National Science Centre in Poland (2016/22/Z/NZ8/00121) through the 2015–2016 BiodivERsA COFUND call for research proposals, with the national funders ANR/DLR-PT/UEFISCDI/NCN/ RCN. We thank Aida Parres, Danuta Frydryszak, Carlos Bautista, Katarzyna Chrzaz scik, and Max Murgio for their help during the fieldwork and Tomasz Zwijacz-Kozica for providing the GPS locations of brown bear clusters. Tatra National Park provided the necessary permits to conduct the field work. A stimulating discussion with Sam Steyaert and comments made by two anonymous reviewers improved the overall quality of this manuscript. AGR and NS conceived the study, designed the methodology, and conducted the fieldwork. AGR performed all statistical analyses and wrote a first draft of the manuscript with significant contributions of NS. The authors declare no conflict of interest | es_ES |
