Big questions, big science: meeting the challenges of global ecology. Repositório Alice
SCHIMEL, D.; KELLER, M..
Ecologists are increasingly tackling questions that require significant infrastucture, large experiments, networks of observations, and complex data and computation. Key hypotheses in ecology increasingly require more investment, and larger data sets to be tested than can be collected by a single investigator?s or s group of investigator?s labs, sustained for longer than a typical grant. Large-scale projects are expensive, so their scientific return on the investment has to justify the opportunity cost-the science foregone because resources were expended on a large project rather than supporting a number of individual projects. In addition, their management must be accountable and efficient in the use of significant resources, requiring the use of formal...

NEON terrestrial field observations: designing continental-scale, standardized sampling. Repositório Alice
KAO, R. H.; GIBSON, C. M.; GALLERY, R. E.; MEIER, C. L.; BARNETT, D. T.; DOCHERTY, K. M.; BLEVINS, K. K.; TRAVERS, P. D.; AZUAJE, E.; SPRINGER, Y. P.; THIBAULT, K. M.; MCKENZIE, V. J.; KELLER, M.; ALVES, L. F.; HINCKLEY, E-L. S.; PARNELL, J.; SCHIMEL, D..
Rapid changes in climate and land use and the resulting shifts in species distributions and ecosystem functions have motivated the development of the National Ecological Observatory Network (NEON). Integrating across spatial scales from ground sampling to remote sensing, NEON will provide data for users to address ecological responses to changes in climate, land use, and species invasion across the United States for at least 30 years. Although NEON remote sensing and tower sensor elements are relatively well known, the biological measurements are not. This manuscript describes NEON terrestrial sampling, which targets organisms across a range of generation and turnover times, and a hierarchy of measurable biological states. Measurements encompass species...
