The Southern Ocean is a climatically important region, and its large-scale circulation influences climate and climate change globally. Through the uptake of carbon and heat from the atmosphere, and through […]
Environmental change is a major threat to marine ecosystems worldwide. Understanding the key biological processes and environmental factors mediating spatial and temporal species’ responses to habitat alterations underpins our ability […]
Coastal ecosystems, including estuaries, are increasingly pressured by expanding hypoxic regions as a result of human activities such as increased release of nutrients and global warming. Hypoxia is often defined […]
75 taxa of Protozoa (18 flagellates, 9 naked rhizopods, 20 testate rhizopods and 28 ciliates) were found in 14 samples of mineral materials, peats, soils and guano collected from the […]
Duct coupling, in which part of the energy of a downcoming whistler-mode wave becomes trapped in a different duct after upward reflection in the ionosphere, manifests itself in the phenomenon […]
The pattern of growth, timing and magnitude of seasonal changes in body weight and condition were compared between male and female reindeer. The data were derived from 300 animals shot […]
Population structure and growth of Philine gibba Strebel have been examined using weight- and length-frequency analyses. The population consisted of five year classes but the 4th and 5th year classes […]
