Definition of biogeochemical in English:



  • Relating to or denoting the cycle in which chemical elements and simple substances are transferred between living systems and the environment.

    • ‘Technically, this is called ‘closing the biogeochemical cycle.’’
    • ‘This study was conducted as part of a five-year interdisciplinary project funded by the National Science Foundation to investigate the consequences of greenhouse warming for biocomplexity and biogeochemical cycles.’
    • ‘Aquatic sediments host much of the bacterial biomass and biodiversity and play a key role in biogeochemical cycles.’
    • ‘Alteration in catchment subsurface water balances through land-use change and pumping can affect lake biogeochemical cycles through changes in groundwater flow rates.’
    • ‘Megaphylls altered the evolutionary trajectory of terrestrial plant and animal life, the biogeochemical cycling of nutrients, water and carbon dioxide and the exchange of energy between the land surface and the atmosphere.’
    • ‘First, while the basic biogeochemical characteristics of environmental change are generally understood, there remain major uncertainties about the feedback effects on both the physical and social processes.’
    • ‘The complex biogeochemical transformations that occur in wetlands have the ability to attenuate contaminants in runoff waters coming from a variety of human activities.’
    • ‘Indirect effects are feedbacks on ecosystem structure and function through many pathways, which include altered competitive relationships among species, biogeochemical cycles and carbon budgets.’
    • ‘An experimental design was set up in autumn 1997 in this stand to study the biogeochemical cycles of nutrients.’
    • ‘Taken together, these analyses suggest that the ongoing disruption of climate and biogeochemical systems by humans may obscure the relationship between aquatic biodiversity and ecosystem function in the future.’
    • ‘There can consequently be rapid changes in the bacterial community to maintain efficient processing of energy sources, and hence stable biogeochemical cycles.’
    • ‘A ‘critical load of acidity’ affects the sustainability of biogeochemical cycling in the ecosystem, while a ‘critical nutrient load’ affects the biodiversity within ecosystems.’
    • ‘Chapters devoted to how the biosphere is energized and how that energy powers biogeochemical cycles follow.’
    • ‘These so-called biogeochemical cycles are linked: changes in the cycling of oxygen, carbon, nitrogen, and phosphorus are interdependent.’
    • ‘We discuss the ecological and biogeochemical implications of these results.’
    • ‘Thus, the surface to volume ratio should be related to silicic acid flows in size-based biogeochemical models of planktonic ecosystems.’
    • ‘This component of the trees is largely involved in the biogeochemical cycles in forest ecosystems, through nutrient removals at harvest and nutrient translocations throughout stand rotation.’
    • ‘Improvement of models of anthropogenic effects on estuarine food webs requires knowledge of the ecological and biogeochemical significance of the different organic matter sources among and within estuaries.’
    • ‘The overall bacterial processing of iron is thought to play a substantial role in the biogeochemical cycling of iron in the ocean.’
    • ‘Therefore, it is important to understand the interaction of any release with the environment, particularly in relation to the biogeochemical cycles, so that any likely environmental impact can be assessed.’
