3 Dec 2015 Team named to target Costa Ballena success Six players from the England men’s A squad will bid to regain the trophy in the Costa Ballena International Quadrangular Tournament in Spain on January 20-22. They are: Ben Amor of Wiltshire (image © Leaderboard Photography), Will Enefer of Shropshire & Herefordshire, Scott Gregory of Hampshire, Josh Hilleard of Somerset, Will Whiteoak of Yorkshire and Andrew Wilson of Durham. The Costa Ballena competition is played on a round robin basis against teams from Finland, Germany and the hosts, Spain. England won the tournament in 2014 and were only beaten in a title decider on the final day last year. The players: Ben Amor, 20, (Marlborough) was in England’s winning Costa Ballena team in 2014. Last season he was runner up in the Darwin Salver and led the southern qualifiers for the Brabazon Trophy, where he went on to finish 15th. Will Enefer, 18, (Wrekin) represented England in the Boys’ Home Internationals. He was runner-up in the German boys’ amateur and had eight top ten finishes in the 2015 season. Scott Gregory, 21, (Corhampton) was in last year’s Costa Ballena team. He was third on the England Golf men’s order of merit with results including fourth place in the European Amateur and second in the Lagonda Trophy. Josh Hilleard, 20, (Farrington Park) was fourth on the men’s order of merit after a season in which he was top qualifier at the English amateur and won both the Midlands amateur and North of England Youths. Will Whiteoak, 21, (Shipley) won the Tillman Trophy and led the northern qualifiers for the Brabazon Trophy, alongside a number of top 20 finishes. Andrew Wilson, 21, (Wynyard) was runner-up in the North of England Youths and was 10th in the French amateur stroke play.
Linking extreme interannual changes in prey availability to foraging behaviour and breeding investment in a marine predator, the macaroni penguin
Understanding the mechanisms that link prey availability to predator behaviour and population change is central to projecting how a species may respond to future environmental pressures. We documented the behavioural responses and breeding investment of macaroni penguins Eudyptes chrysolophus across five breeding seasons where local prey density changed by five-fold; from very low to highly abundant. When prey availability was low, foraging trips were significantly longer and extended overnight. Birds also foraged farther from the colony, potentially in order to reach more distant foraging grounds and allow for increased search times. These extended foraging trips were also linked to a marked decrease in fledgling weights, most likely associated with reduced rates of provisioning. Furthermore, by comparing our results with previous work on this population, it appears that lowered first-year survival rates associated, at least partially, with fledging masses were also evident for this cohort. This study integrates a unique set of prey density, predator behaviour and predator breeding investment data to highlight a possible behavioural mechanism linking perturbations in prey availability to population demography.
