Yet the proximate mechanisms influencing differential maternal allocation in relation to male sexiness are poorly known. Here, we studied the importance of visual stimulation for maternal allocation in the Houbara bustard, a vulnerable bird species bred in captivity to support wild populations. Artificial insemination allowed controlling for potential confounding factors, such as a male's territory quality, social interactions or sperm quality\/quantity, probably linked to mate attractiveness. We show that artificially inseminated females stimulated by highly displaying males increased their hatching success, owing to increased fertilization success. The females also increased the allocation of maternal androgens in their eggs, leading to an increase of circulating testosterone and growth rate in chicks. Hence, visual stimulation of the females can promote differential maternal allocation and favour offspring fitness. Our results further suggest that using artificial insemination for species conservation without appropriate stimulation of the breeding females probably has negative impacts on their breeding performance and therefore on population viability.<\/jats:p>","DOI":"10.1098\/rspb.2010.0473","type":"journal-article","created":{"date-parts":[[2010,6,11]],"date-time":"2010-06-11T01:04:22Z","timestamp":1276218262000},"page":"3453-3460","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":22,"title":["Watching sexy displays improves hatching success and offspring growth through maternal allocation"],"prefix":"10.1098","volume":"277","author":[{"given":"Adeline","family":"Loyau","sequence":"first","affiliation":[{"name":"Emirates Center for Wildlife Propagation, 33250 Missour, Morocco"},{"name":"Department of Conservation Biology, Helmholtz Centre for Environmental Research\u2014UFZ, Leipzig, Germany"},{"name":"Station d'Ecologie Exp\u00e9rimentale du CNRS \u00e0 Moulis, USR 2936, 09200 Saint Girons, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fr\u00e9d\u00e9ric","family":"Lacroix","sequence":"additional","affiliation":[{"name":"Emirates Center for Wildlife Propagation, 33250 Missour, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2010,6,10]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2005.3081"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.1086\/284877"},{"key":"e_1_3_2_4_1","volume-title":"Model selection and multimodel inference: a practical information-theoretic approach.","author":"Burnham K.
