The relationships between prey abundance, diet and individual fitness have often been explored. However, these relationships are complex and difficult to disentangle, especially in vertebrate top predators. Here, we present the results of a long\u2010term study using multi\u2010model inference procedures to elucidate the influence of diet\u2010related variables on breeding parameters and home range behaviour of a top predator, the eagle owl\n                    <jats:italic>Bubo bubo<\/jats:italic>\n                    . Superpredation, diet diversity, rat biomass and rabbit mean weight were the most important variables when analysing reproductive parameters, suggesting that less diverse diets with greater rabbit biomass percentage may benefit reproductive performance, whereas rat biomass percentage is apparently associated with greater variation of breeding success. Earlier laying dates seem to be associated with the consumption, on average, of smaller rabbits. On the other hand, edge density was the most relevant factor determining the variation in home range behaviour, with individual characteristics, such as age and sex, also being important. Although the relative importance of the diet\u2010related variables was generally low, mean weight of alternative prey, diet diversity and rabbit biomass also helped to explain home range parameters. In an optimal foraging context, centred on the abundance of the main prey species, our results suggest that when rabbits are less available eagle owls may increase home range size in order to obtain alternative prey, increasing at the same time their dietary diversity, which may also require higher movement speed.\n                  <\/jats:p>","DOI":"10.1007\/s10144-015-0506-1","type":"journal-article","created":{"date-parts":[[2015,9,1]],"date-time":"2015-09-01T23:50:44Z","timestamp":1441151444000},"page":"625-636","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Evaluating the influence of diet\u2010related variables on breeding performance and home range behaviour of a top predator"],"prefix":"10.1002","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7694-0478","authenticated-orcid":false,"given":"Rui","family":"Louren\u00e7o","sequence":"first","affiliation":[{"name":"Labor\u2010Laboratory of Ornithology, Instituto de Ci\u00eancias Agr\u00e1rias e Ambientais Mediterr\u00e2nicas Universidade de \u00c9vora\u2010N\u00facleo da Mitra Ap. 94 7002\u2010554 \u00c9vora Portugal"}]},{"given":"Maria del Mar","family":"Delgado","sequence":"additional","affiliation":[{"name":"Department of Conservation Biology Estaci\u00f3n Biol\u00f3gica de Do\u00f1ana, CSIC c\/Americo Vespucio s\/n 41092 Seville Spain"},{"name":"Metapopulation Research Group, Department of Biosciences University of Helsinki 00014 Helsinki Finland"}]},{"given":"Letizia","family":"Campioni","sequence":"additional","affiliation":[{"name":"MARE, Marine and Environmental Sciences Centre ISPA Instituto Universit\u00e1rio Rua Jardim do Tabaco 34 1149\u2010041 Lisbon Portugal"}]},{"given":"Erkki","family":"Korpim\u00e4ki","sequence":"additional","affiliation":[{"name":"Section of Ecology, Department of Biology University of Turku 20014 Turku Finland"}]},{"given":"Vincenzo","family":"Penteriani","sequence":"additional","affiliation":[{"name":"Department of Conservation Biology Estaci\u00f3n Biol\u00f3gica de Do\u00f1ana, CSIC c\/Americo Vespucio s\/n 41092 Seville Spain"},{"name":"Research Unit of Biodiversity (UMIB, UO\u2010CSIC\u2010PA) Oviedo University\u2010Campus Mieres 33600 Mieres Spain"}]}],"member":"311","published-online":{"date-parts":[[2015,9,3]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"BartonK(2013)MuMIn: multi\u2010model inference.R package version 1.9.5.http:\/\/CRAN.R\u2010project.org\/package=MuMIn.
