1. Cretaceous (Wealden) climates: a modelling perspective

   This paper describes the results from a new palaeoclimate modelling exercise for the Early Cretaceous (Barremian) focussed on the Weald (SE England), using a Limited Area Numerical Climate Model (LAM). […]

3. Modelling Pliocene warmth: contribution of atmosphere, oceans and cryosphere

   The relative role of the atmosphere, oceans and cryosphere in contributing towards middle Pliocene warmth (ca 3 Ma BP) is investigated using the HadCM3 coupled ocean-atmosphere general circulation model. The […]

4. Habitat moisture availability and the local distribution of the Antarctic Collembola Cryptopygus antarcticus and Friesea grisea

   Population densities of the Collembola Cryptopygus antarcticus and Friesea grisea were compared in two maritime Antarctic habitats with different moisture availability. C. antarcticus was absent from the drier rock platform […]

5. The relationship of Pacific deep tropical convection to the winter and springtime extratropical atmospheric circulation of the South Pacific in El Niño events

   During some El Nino events Rossby wave trains (RWT) are observed to strongly modulate the seasonal atmospheric circulation of the South Pacific extratropics in the austral winter and spring. Here […]

6. The impact of winter ice retreat on Antarctic winter sea-ice extent and links to the atmospheric meridional circulation

   15 years of weekly Antarctic ice extent and 10 m winds from numerical meteorological reanalyses have been used to test the hypothesis that the Antarctic final winter ice extent (FWE) […]

7. Telomere loss in relation to age and early environment in long-lived birds

   Shortening of telomeres, specific nucleotide repeats that cap eukaryotic chromosomes, is thought to play an important role in cellular and organismal senescence. We examined telomere dynamics in two long-lived seabirds, […]

8. Effects of long-term implanted data loggers on macaroni penguins Eudyptes chrysolophus

   We tested the hypothesis that implanted data loggers have no effect on the survival, breeding success and behaviour of macaroni penguins Eudyptes chrysolophus . Seventy penguins were implanted with heart […]

9. Energetics of the moult fast in female macaroni penguins Eudyptes chrysolophus

   The metabolic rate of moulting macaroni penguins Eudyptes chrysolophus was investigated using three techniques in order to test two hypotheses concerning the energetic cost of the moult fast in penguins. […]

10. Long-term interannual cycles of the gametogenic ecology of the Antarctic brittle star Ophionutus victoriae

    Spermatogenesis, oogenesis and fecundity are described and the gonad index calculated for 10 individuals from each month using histological and image analysis techniques for the Antarctic brittle star Ophionotus victoriae […]

11. Sexual size dimorphism in northern giant petrels: ecological correlates and scaling

    Northern giant petrels (Macronectes halli) are among the largest and most sexually size dimorphic species of seabirds, with females being only 80% the mass of males. Both sexes scavenge on […]

12. Regulation of incubation shifts near hatching by giant petrels: a timed mechanism, embryonic signalling or food availability?

    In most seabird species incubation shifts shorten when hatching approaches, a behavioural response allowing the chick to be fed soon after hatching. Three mechanisms have been proposed to explain these […]
