Eden Hazard scored his first goal of the season as Chelsea built on Oscar’s first-half hat-trick to cruise towards the fifth-round of the FA Cup.The Belgian won a penalty 10 minutes after the break and coolly slid home the spot-kick for his first goal in his 29th appearance of the season before celebrating in front of the near 7000 travelling fans.And Hazard then set up substitute Bertrand Traore to make it 5-1.Chelsea were already in control at half-time after a thrilling, and astonishingly open, first half.Diego Costa made the most of a terrible Kyle McFadzean backpass to lay on a simple opener for Oscar.And although MK Dons levelled against the run of play through Darren Potter’s deflected long-range strike, Oscar’s tidy finish and sumptuous curler put Chelsea in control.Eden Hazard, on his first start since limping off early in the 3-0 win over Crystal Palace, was the key man in a dominant Chelsea display.He helped create three early chances, once for Costa via Oscar that produced a good save from keeper David Martin, and then twice teeing up Oscar, who miscued from 12 yards on both occasions.Rob Hall and Jake Forster-Caskey’s pace posed a few problems for the away side, but Chelsea controlled possession and created opportunities at will.Branislav Ivanovic had a shot blocked and Costa then made it 1-0, but the Championship strugglers levelled when Potter’s 20-yard strike from the edge of the box took a huge deflection off Matic and looped over Thibaut Courtois.Hazard also squandered a glorious one-on-one opportunity, but a clever Ruben Loftus-Cheek pass put Oscar clear inside the box and he finished tidily across Martin to make it 2-1.And the Brazilian completed his treble with his best effort just before the break, running across the box and curling home a stunning strike.Hazard’s strike, after a foul by Potter, and Traore’s first Blues goal made the tie safe after the interval and the score 5-1 with 20 minutes remaining.Chelsea: Courtois; Ivanovic, Cahill, Terry, Baba; Matic, Fabregas; Oscar, Loftus-Cheek, Hazard; Costa.Subs: Begovic, Azpilicueta, Zouma, Mikel, Pedro, Willian, Traore.Follow West London Sport on TwitterFind us on Facebook
The devil is in the detail: small-scale sexual segregation despite large-scale spatial overlap in the wandering albatross
Sexual segregation in foraging habitat occurs in many marine predators and is usually attributed to competitive exclusion, different parental roles of each sex or niche specialisation associated with sexual size dimorphism. However, relatively few studies have attempted to understand the patterns and underlying drivers of local-scale sexual segregation in marine predators. We studied habitat use, diet and feeding ecology of female and male wandering albatrosses Diomedea exulans, fitted with GPS and stomach-temperature loggers during the chick-rearing period (austral winter) at South Georgia in 2009. During this period, when oceanographic conditions were anomalous and prey availability was low in waters near the breeding colony, the tracked wandering albatrosses showed high consistency in their foraging areas at a large spatial scale, and both males and females targeted sub-Antarctic and subtropical waters. Despite consistency in large-scale habitat use, males and females showed different foraging behaviours in response to oceanographic conditions at a smaller scale. Males appeared to be more opportunistic, scavenging for offal or non-target fish discarded by fishing vessels in less productive, oceanic waters. They exhibited sinuous movements, feeding mostly on large prey and consuming similar amounts of food during the outbound and return parts of the foraging trip. In contrast, females targeted natural productivity hotspots, and fed on a wide variety of fish and cephalopods. They commuted directly to these areas; most prey were ingested on the outbound part of the trip, and they often started their return after ingesting large prey at the farthest point from the colony. Together, these results indicate that sexual segregation in core foraging areas of wandering albatrosses is driven by sex-specific habitat selection due to the low availability of prey in local Antarctic waters. This segregation results in different feeding behaviour at local scales which may be explained by differing breeding roles and degree of parental investment by each sex, with females investing more than males in reproduction. Further investigations are necessary to confirm the existence of this pattern through time under contrasting environmental conditions and to identify the drivers responsible for local-scale sexual segregation in wandering albatrosses.
