The microstructure and location of impurities in polar ice are of great relevance to ice core studies. We describe a reliable method to examine ice in the scanning electron microscope […]
Colonization by alien species poses one of the greatest threats to global biodiversity1. Here I investigate the colonization by marine organisms of drift debris deposited on the shores of 30 […]
There is a complex and dynamic interrelationhip between hermit crabs, humans and the coastal environment. Hermit crab homes (shells) are often hard to come by, but humans are helping out […]
Two clades of marine bryozoans, cyclostomes and cheilostomes, exemplify the benefits of applying a multidisciplinary approach to the interpretation of long-term evolutionary patterns. The cyclostome bryozoans were dominant in the […]
In marine ecosystems, characterisation of the foraging areas and habitats of predators is a key factor in interpreting their ecological role, We studied the foraging areas of the macaroni penguin […]
Understanding how parental expenditure reflects food availability and influences reproductive output is a key part of studies of breeding performance. Provisioning behaviour is an important aspect of parental expenditure. We […]
During Leg 178, multiple advanced piston corer holes were drilled at our sites (1095, 1096, 1098, and 1099). Cores from the holes were correlated on board to produce composite depths […]
The Pacific margin of the Antarctic Peninsula was drilled during Ocean Drilling Program (ODP) Leg 178 to understand the past 10 m.y. of its glacial history and to test a […]
We used the otoliths from a sample of Dissostichus eleginoides pre-recruits, whose length density was distinctly polymodal, to see whether ages estimated by reading otoliths were congruent with the length […]
Plasma leptin levels were determined in 8 lactating female and 20 pup Antarctic fur seals (Arctocephalus ga:ella) during fasting periods of normal duration. Plasma leptin levels ranged from 1.35-3.19 ng.ml(-1) […]
