At the close of the Fourth International Polar Year, we take stock of the ecological consequences of recent climate change in the Arctic, focusing on effects at population, community, and ecosystem scales.
It further states that research on living resources in the Gulf show long term ecological changes in species diversity and a large scale, often rapid change, in the ecosystem's food - web that is both «difficult and impossible to reverse.»
Given the obvious concerns for human ecological health — in terms of climate change, heavy metal toxification, indoor air quality, air pollution, plastics in the oceans, and things like that — there will be a large - scale trend to buildings that start to act like organisms.
Organisation and dynamics of biocoenosis; biodiversity patterns at various scales; hydrobiology of running and standing waters and wetlands; ecological effects of climate and land use changes; conservation biology and restoration ecology; new plant resources; natural vegetation in Hungary; maintenance of the Botanical Garden.
Introducing NEON: The National Ecological Observatory Network was created to understand and forecast the impacts of climate change, land use change, and invasive species on continental - scale ecology by providing an observational infrastructure to support research, education, and environmental management in these areas.
A particular challenge for science is the growing evidence that social - ecological interactions across scales can generate regime shifts where profound and abrupt changes can occur in systems ranging from local ecosystems (such as lakes) to large biomes (such as the Arctic); from local communities (such as farming systems) to regional economic sectors (e.g., global fisheries).
Funded by the National Science Foundation and operated by Battelle, The National Ecological Observatory Network (NEON) provides open, continental - scale data that characterize and quantify complex, rapidly changing ecological Ecological Observatory Network (NEON) provides open, continental - scale data that characterize and quantify complex, rapidly changing ecological ecological processes.
While BCDR promises some direct (climate) and ancillary (restoration, habitat protection) benefits, Pg C - scale implementation may be constrained by ecological factors, and may compromise the ultimate goals of climate change mitigation.
Land managers have realized that static protected areas will not be sufficient to conserve biodiversity in a changing climate, requiring an emphasis on landscape - scale conservation, connectivity among protected habitats, and sustaining ecological functioning of working lands and waters.
BTW there are many serious ecological economists (myself among them) who believe that the thermodynamics problem is moot, and that climate change is the primary constraint on scale.
What are the large - scale consequences of ongoing ecological changes for social systems and human security, and are the impacts gender - differentiated?
What kind of catastrophe can not be predicted, but numerous candidates have been discussed in this book: ecological collapses of various kinds, large - scale crop failures due to ecological stress or changes in climate and leading to mass famine; severe resource shortages, which could lead either to crop failures or to social problems or both; epidemic diseases; wars over diminishing resources; perhaps even thermonuclear war.»
Yes conservation is important, not least in ensuring that species can migrate to deal with climate changes and other environmental disruptions, but the scale of human activity is such that we are collectively making the future ecological conditions of the planet.
Future coupling of demography with existing global land model predictions could enable assessment of these potentially important die - off responses [44], as well as implementation of more realistic reductions in tree loss to drive scenarios (i.e., enabling assessments of ecological changes less drastic or occurring on shorter time - scales than conversion from forest to grassland biomes).
Our results illustrate the utility of global scale analyses that can aide in identifying potential ecoclimate teleconnections affected by vegetation change at regional scales, while simultaneously providing insight into the mechanisms of the associated ecological responses in affected regions.
It is unknown whether the ecosystem will return to the pattern of decadal - scale change exhibited in previous decades, or how polar bears and seals will respond to ecological changes in the future, but research on these topics is a high priority.
Private and public sector organizations face significant obstacles to adaptation: uncertainty regarding future climate change at regional and local scales; uncertainty regarding the future frequency of extreme weather events; and uncertainty regarding the ecological, economic and other impacts of climate change.
Weeds as ecological and climate change opportunists The resilience of weeds is due to their genetic diversity, something that is deliberately bred out of our industrialized crop plants in the interest of increased yields with large - scale genetic uniformity.
