Revisited phytoplanktonic carbon dependency of heterotrophic bacteria in freshwaters, transitional, coastal and oceanic waters.
Positive relationships between heterotrophic bacteria and particulate phytoplankton production (respectively, BP and PPP) have been reported for several areas, suggesting that material produced by phytoplankton was a major substrate for bacterial growth. Since then, thousands of simultaneous measurements of both PPP and BP have been performed. A review of these data showed that BP may exceed PP...
متن کاملScale-dependent carbon : nitrogen : phosphorus seston stoichiometry in marine and freshwaters
The classical Redfield ratio of carbon106 : nitrogen16 : phosphorus1 is a cornerstone of biogeochemistry. With the use of .2,000 observations of the chemistry of particulate matter from small and large lakes, as well as nearand off-shore marine environments, we found that the best model to describe seston stoichiometry depended on the scale of analysis. We also found that there were better esti...
متن کاملTransitional states in marine fisheries: adapting to predicted global change.
Global climate change has the potential to substantially alter the production and community structure of marine fisheries and modify the ongoing impacts of fishing. Fish community composition is already changing in some tropical, temperate and polar ecosystems, where local combinations of warming trends and higher environmental variation anticipate the changes likely to occur more widely over c...
متن کاملAdaptive Diversity: Hormones and Metabolism in Freshwaters
Genes underlying the evolution of morphological traits have recently been identified in a number of model species. In the stickleback, the metabolic adaptations to a freshwater habitat have now been linked to a well-known hormonal system.
متن کاملStructural Acoustics and Hydroacoustics Phenomena in Finite Fluid
Long-term Research Objective: The scientific objectives of this project are: 1. To describe and characterize the physical mechanisms which determine how most of the noise radiates from a finite fluid-filled pipe with turbulent flow. 2. To determine criteria which estimate the relative importance of these various mechanisms. 3. To develop experimental and analytical techniques for investigating ...
