Long-Term Ecological Monitoring

Ecological and genetic correlates of long-term population trends in the park grass experiment.

The Park Grass Experiment (PGE) is the longest-observed set of experimental plant communities in existence. Although the gross composition of the vegetation was at equilibrium over the 60-yr period from 1920 to 1979, annual records show that individual species exhibited a range of dynamics. We tested two hypotheses to explain why some species initially increased and why subsequently some of the...

Ecological Informatics: a Long-Term Ecological Research Perspective

Scientists within the Long-Term Ecological Research (LTER) Network have provided leadership in ecological informatics since the inception of LTER in 1980. The success of LTER, where research projects span wide temporal and spatial scales, depends on the quality and longevity of the data collected. Scientists have devised data collection, data entry, data access, QA/QC and archiving strategies f...

Adding values: an experiment in systematic attention to values and preferences of community long-term care clients.
