Editor's Choice Extraterritorial forays by great tits are associated with dawn song in unexpected ways The dawn chorus is a familiar feature of sunrise to any who have ventured out camping, and its function has long puzzled behavioural ecologists. Several hypotheses have been proposed, including the idea that it serves as a paternity guard against rival males who may use the cover of twilight to enter a male’s territory and mate with his partner. An alternative explanation is that dawn singing serves to attract females for mating. In this article, Nina Bircher and her colleagues provide one of the largest radiotracking data sets ever published, following 66 great tits on more than 30,000 excursions into their neighbour’s territories at dawn. They found that females stayed away from territories of males with elaborate singing, whereas males were attracted to such territories. Clearly dawn singing does not repel rivals or attract extra mates. Neither did male or female forays predict extra-pair paternity, suggesting that sperm competition avoidance is unlikely to explain dawn singing, at least in these great tits. An explanation for dawn singing must remain, for now, an enduring puzzle.Read the article now Male harassment leads to fitness costs for females by disrupting oviposition site preferences Far from being a harmonious exercise, reproduction for males and females can often generate conflicts of interest. Seed beetles have been widely used to study sexual conflict. In seed beetles males directly harm females during mating in order to maximize their paternity share, but in so doing reduce female lifespan and productivity. Female beetles are understandably reticent to mate more than once. In this article, Elisabeth Bacon and Flavia Barbosa show that males can also harm a female’s offspring. When females are harassed for mating access they are unable to exercise their choice of egg laying substrate, so that eggs are laid on poor quality resources that reduce the survival of offspring. These findings illustrate the transgenerational costs of sexual conflict.Read the article now Ocean warming increases availability of crustacean prey via riskier behavior We often rely on predictive models to inform us of how animal populations might be affected by climate change. But experimental studies are needed to test those predictions. On pages 287-291 of this issue, Emma Marangon and her colleagues’ established experimental marine mesocosms that had temperature and carbon dioxide levels elevated to those predicted for 2100 by climate models under a business as usual scenario. The 2.7°C increase in temperature resulted in an increase in risky foraging behavior of two species of shrimp that are prey to predatory fishes. This does not mean that climate change will be beneficial. In the short term it may well be that increased availability of prey will benefit predator, but increased predation could result in prey extinction with detrimental impact on the food web as a whole. What these results do tell us is that climate change will have significant and unpredictable consequences for ecosystem functioning.Read the article now About ISBE Find out more about the International Society for Behavioral Ecology.Visit the ISBE homepage Editorial Office Contact the Editorial Office if you have any queries relating to Behavioral Ecology.Get in touch Become an ISBE Member Discover the benefits of becoming a member of the International Society for Behavioral Ecology.Find out more Facebook Stay up to date with the latest news and content from the International Society for Behavioral Ecology.Visit our Facebook page Email alerts Register to receive table of contents email alerts as soon as new issues of Behavioral Ecology are published online.Sign up Twitter Keep informed of the latest updates by following the official Twitter account of Behavioral Ecology.Follow us on Twitter Related Titles Current Zoology Journal of Heredity Molecular Biology and Evolution ICES Journal of Marine Science Journal of Plankton Research Journal of Molluscan Studies Journal of Mammalogy Mammalian Species Journal of Urban Ecology Journal of Language Evolution Journal of Crustacean Biology Integrative Organismal Biology Oxford University Press is a department of the University of Oxford.
