New Understanding Of Biological Systems On Regional To Continental Scales
National Science Foundation
Macrosystems biology awards support predictive understanding of large-scale biological responses to climate, land-use change
Have you looked closely at a local pond, meadow or forest and observed changes in it over time? That's exactly what scientists are trying to do on a larger, regional to continental scale--a macrosystems biology scale.
To better detect, understand and predict the effects of climate and land-use change on organisms and ecosystems at regional to continental scales, the National Science Foundation (NSF) Directorate for Biological Sciences recently awarded $15.3 million in 10 new macrosystems biology grants.
Since the Macrosystems Biology program was launched in 2011, NSF has made 50 such awards.
How will the biosphere respond to natural and human-induced changes across a range of time and space scales? What is the pace and pattern of these responses? What are the effects on ecosystem services--such as the availability of freshwater--across regions and continents?
"Scientists conducting macrosystems biology research are working to find answers to these complex questions," says John Wingfield, NSF assistant director for Biological Sciences.
"Current knowledge of the biosphere is largely based on research in small plots of land and on satellite-scale remote sensing," says Wingfield. "But the insights needed to answer critically important questions about the biosphere's future can't always be extrapolated from such studies. They require new approaches."
A significant part of these new approaches involves the integration of biology with other fields, Wingfield says, including the geosciences, engineering, mathematical and physical sciences, and social, economic and behavioral sciences.
Among the questions NSF's macrosystems biology awardees will ask are:
How are regional-scale processes in plant and animal invasions, and in disease transmission, shaped by continent-wide environmental and land-use patterns? How can continent-wide data lead to better forecasts of disease outbreaks? How do invasive species and infectious diseases arrive at new locations, sometimes across great distances?
Projects include studies of the influence of time and space scales on host-parasite interactions; modeling birds' responses to climate change; quantifying climate-forced extinction risks for lizards, amphibians, fish and plants; building local effects of forest management into Earth system models at continental scales; and investigating methane emissions from far Northern peatlands.
The projects criss-cross regions and continents, and bring together scientists from biological sciences, geosciences and other fields in an effort to find out what makes Earth's biosphere tick.
