Complementarity in marine biodiversity manipulations: reconciling divergent evidence from field and mesocosm experiments.
Mounting concern over the loss of marine biodiversity has increased the urgency of understanding its consequences. This urgency spurred the publication of many short-term studies, which often report weak effects of diversity (species richness) driven by the presence of key species (the sampling effect). Longer-term field experiments are slowly accumulating, and they more often report strong div...
متن کاملUV effects on marine planktonic food webs: A synthesis of results from mesocosm studies.
UV irradiance has a broad range of effects on marine planktonic organisms. Direct and indirect effects on individual organisms have complex impacts on food-web structure and dynamics, with implications for carbon and nutrient cycling. Mesocosm experiments are well suited for the study of such complex interrelationships. Mesocosms offer the possibility to conduct well-controlled experiments with...
متن کاملThinking Towards Peace: On Triades and New Cosmology of the Mesocosm
This paper has three parts. In the first part, we bring to the fore an ancient Vedic concept of mesocosm and discuss its religious and cosmic significance within Indian religion. This part also brings an initial approach towards philosophy of spirituality by focusing on the role of breath within the very concept of mesocosm. In the second part, based on our preliminary analysis, we present an o...
متن کاملImproving marine ecosystem models: Use of data assimilation and mesocosm experiments
Our inability to accurately model marine food webs severely limits the prognostic capabilities of current generationmarine biogeochemistrymodels. To address this problem we examine the use of data assimilation and mesocosm experiments to facilitate the development of food web models. The components of the data assimilation demonstrated include the constructionof measurement models, the adjoint ...
متن کاملProtozoan grazing on planktonic bacteria and its impact on bacterial population
Grazing by heterotrophic nanoflagellates and < 100 Fm microzooplankton on planktonic bacteria was followed during a mesocosm experiment in the Baltic Sea between 23 July and 12 August 1988 on the SW coast of Finland. During the succession of the planktonic community in one mesocosm, 4 grazing experiments were run with a size-fractionation technique. The size fractions used were: < 1 pm (bacteri...
