Mesozooplankton distribution and community structure was investigated during 3 cruises to the Scotia Sea in austral spring, summer and autumn. Three mesh sizes of Bongo nets were used during each […]
Many mobile animals migrate because of the different benefits provided by different localities in time and space. For hermit crabs, such benefits include resource (shell, water, food) acquisition and gamete […]
Most organisms experience competition for resources, probably most of the time. As the structure and requirements of closely related species are generally liable to be more similar than in distantly […]
[1] The International Photolysis Frequency Measurement and Model Intercomparison (IPMMI) took place in Boulder, Colorado, from 15 to 19 June 1998, aiming to investigate the level of accuracy of photolysis […]
In vivo P-31-nuclear magnetic resonance (NMR) spectroscopy was used to measure the levels of ATP, phospho-L-arginine (PLA), and inorganic phosphate in the adductor muscle of the Antarctic scallop Adamussium colbecki […]
The few existing measurements of deep-sea fish physiology consistently indicate reduced basal metabolism and metabolic power. A possible explanation for this is the reduction in selective pressure for burst activity […]
The response of rhizosphere microbial communities associated with natural populations of Deschampsia antarctica growing on Leonie Island (67degrees36’S, 68degrees21’W, Antarctic Peninsula) to UV radiation was investigated. UV radiation was controlled […]
The diet of black-browed albatrosses was studied at Gonzalo Island, Diego Ramirez, Chile, during the early chick-rearing periods of 2000, 2001, and 2002. Diet composition was determined by sampling chick-stomach […]
A non-linear regression model describing the mass-balance distribution of the whole Vatnajokull ice cap, Iceland, for the years 1992-2000 is presented. All available data from some 40 locations over this […]
Surveys of the microplankton communities of the Scotia Sea, Southern Ocean, were carried out during three separate seasons of interest, spring, summer, and autumn of consecutive years. The surveys were […]
