CCAMLR ecosystem monitoring program standard methods: determination of sex of Adelie penguins
Abstract: The suggestion that sex of Adélie penguins, Pygoscelis adeliae, might be assigned by ... observing which member of the pair (the male) takes the first long incubation shift (Anon. 1991) was ... examined for each of the 1990–91, 1991–92 and 1992–93 breeding seasons. There was an 8- or 9-day period ... when more than 90% of the incubating birds were male and a 6- or 7-day period when more than 90% of the ...

Testing early life connectivity using otolith chemistry and particle-tracking simulations
Abstract: We measured the otolith chemistry of adult Scotia Sea icefish (Chaenocephalus aceratus ... ), a species with a long pelagic larval phase, along the Antarctic Circumpolar Current (ACC) and ... compared the chemistry with simulated particle transport using a circulation model. Material laid down in ... otolith nuclei during early life showed strong heterogeneity between the Antarctic Peninsula and South ...

An assessment of temporal variability and interrelationships between CEMP parameters collected on Adélie penguins at Béchervaise Island
Abstract: We examined temporal variability in a series of CEMP parameters collected over the ... the other parameters were more stable. We also explored the correlation between CEMP parameters, and ... the correlation of each parameter with breeding success. Breeding success was measured in terms of 1 ... ) the absolute number of chicks on the island which fully crèche and 2) the number of chicks crèched per ...
