متن کاملShrinking of fishes exacerbates impacts of global ocean changes on marine ecosystems
Changes in temperature, oxygen content and other ocean biogeochemical properties directly affect the ecophysiology of marine water-breathing organisms1–3. Previous studies suggest that the most prominent biological responses are changes in distribution4–6, phenology7,8 and productivity9. Both theory and empirical observations also support the hypothesis that warming and reduced oxygen will redu...
متن کاملEffects of Global Warming on Marine Ecosystems
Marine ecosystems are very diversified and involved in a complicated net of internal and external intercommunications. Their evolutionary history and present adaptive possibilities strongly depend on variability of climate conditions. Ocean basins in equatorial, tropical, and moderate zones are distinguished by the stability of environmental parameters and less affected by climatic anomalies. O...
متن کاملHistorical changes in arctic freshwater ecosystems.
Various types of ecosystem-based climate proxies have been used to assess past arctic change. Although lotic records are relatively poor because of the constant reworking of riverine material, high-quality lentic data have been assembled back to the end of the Pleistocene and deglaciation of the circumpolar Arctic. In general, climatic variations in the Holocene, partly due to changes in the sh...
متن کاملPattern and control of biomass allocation across global forest ecosystems
The underground part of a tree is an important carbon sink in forest ecosystems. Understanding biomass allocation between the below- and aboveground parts (root:shoot ratios) is necessary for estimation of the underground biomass and carbon pool. Nevertheless, large-scale biomass allocation patterns and their control mechanisms are not well identified. In this study, a large database of global ...
