Behavioural flexibility during year-round foraging in macaroni penguins

first_imgPenguins are major consumers in the marine environment. However, like many top predators, very little information exists on their foraging behaviour outside the breeding season. We investigated the foraging behaviour of the macaroni penguin Eudyptes chrysolophus continuously for 2 consecutive years, from the end of December 2001. This allowed us to investigate whether foraging behaviour varied between sexes, years or phases of the annual cycle. Male penguins tended to dive deeper and longer than female penguins, but at a lower frequency, probably as a result of their larger body size. There was little variation in foraging behaviour between the 2 years studied, although neither year included a notable period of low Antarctic krill abundance. Diving behaviour varied substantially within years and general linear models were used to investigate this variability. In summary, all penguins tended to dive deeper, longer and more efficiently during their winter migration than during the summer breeding season. The penguins dived predominantly during daylight hours at all times of the year, but appeared to be more constrained by daylight during the short winter days. Several diving variables including dive duration, dive rate and amount of time spent diving were significantly related to day length and these associations were stronger during winter than summer. The macaroni penguin shows flexibility in its foraging behaviour as it adapts to differing constraints and challenges during its annual cycle.last_img read more

Senex completes $278m Surat Basin gas development project in Australia

(Credit: 272447 from Pixabay) Australian firm Senex Energy has completed its A$400m ($278m) Surat basin natural gas development project in Queensland, Australia.The project involved the completion of 80 well drilling campaign, down from the originally planned 110 wells.Senex managing director and CEO Ian Davies said that the Surat Basin natural gas development project is implemented with strong support from partners and stakeholders.“In October 2018, Senex reached its Final Investment Decision for this $400 million capital program. Less than two years later, Roma North and Atlas have been successfully delivered – an industry leading achievement and a credit to all involved.“We are proud to have worked closely with our partners Jemena and Easternwell, landholders, community and other stakeholders to successfully develop these critical natural gas resources for the east coast market.“With proved and probable (2P) natural gas reserves in excess of 600 PJ across our Surat Basin acreage, Senex will be delivering natural gas to the domestic market for decades to come.”Senex also commissioned natural gas facilities at Roma North and AtlasSenex said it has also commissioned natural gas facilities at Roma North and Atlas. The two projects deliver a greenfield gas processing infrastructure capacity of over 20PJ a year.In 2019, Senex Energy said it has achieved first gas sales from Project Atlas, nearly two months after bringing the Surat Basin gas project into production.The first gas sales were made into the east coast market ahead of schedule with the buyer being CleanCo, a Queensland-based power generator.Gas from the Project Atlas is supplied at the Wallumbilla Gas Hub in Queensland through a 60km buried pipeline.last_img read more
