FEATURED DATA
New Data Oak Forest Regeneration Study in Pennsylvania (ORSPA)
In this long-term project funded by the Pennsylvania Bureau of Forestry, Dr. Kim Steiner, Dr. Jim Finley, and Dr. E. Zenner of Penn State's Department of Ecosystems Science Management are following the regeneration process in over 50 mixed-oak forest stands.
New Data

Trophic Mismatch: Caribou Phenology. This data from Dr. Eric Post, Department of Biology, records the near daily ratio of caribou calve to adult females at a caribou calving ground located in SW Greenland. Data include the proportion of calves observed relative to the total population of observed caribou on that day for each corresponding year.

New Data

Metabolomics: Coralpos
This data from Dr. Andrew Patterson, Center for Molecular Toxicology and Carcinogenes, is one example of metabolomics data. Metabolomics is a tool for either discovering cellular responses to external stimuli such as toxicant administration or cataloging metabolic pathways in health and disease.
New Data

Impacts of contrasting land-use history on composition, soils, and devlopment of mixed-oak, coastal plain forests on Shelter Island, New York
This dataset by Dr. Marc Abrams, Dept. of Ecosystems Science & Management, shows how contrasting land-use history affected: 1) tree species composition, size, and age structure; 2) soil chemistry and morphology; 3) the dominance of Smilax, a native invasive shrub; and 4) the historical ecology and successional pathways.

New Data

Pocono Birds: Presence and Proportion on Lakes
This dataset by Dr. Rob Brooks, PSU Riparia, is based on a pilot study in 1991 to test a method for sampling avian communities on a series of lakes in northeastern Pennsylvania and to determine whether differences between undisturbed and disturbed sites could be detected from a census period consisting of two surveys taken during the breeding season.

New Data

Air Quality and Awareness of Ground-level Ozone in the Delaware Valley
This report by Dr. Al Luloff and Dr. Mark Brennan, Dept. of Agricultural Economics, summarize a study undertaken by the Delaware Valley Regional Planning Commission on concern about air pollution and awareness of ozone-related issues among residents of the Phila-Wilmington-Trenton metro area.

New Data

Inventory and Assessment of Invertebrate Biodiversity at Gettysburg National Military Park & Eisenhower National Historic Site
This data, from Dr. K.C. Kim, Dept. of Entomology, is a series of taxon-based surveys and research projects conducted to document flora and fauna. Data include presence, abundance, and distribution of resident species of a number of major plant and animal taxa, namely vertebrates and vascular plants.
