title: Synthesis of nitrogen fertilization experiments in North America - plant species relative abundance

description: Nitrogen (N) is a limiting nutrient to plant growth in many ecosystems, and human-caused N enrichment has the potential to fundamentally alter the structure and functioning of plant communities. Nutrient limitation of primary production has been of interest to ecologists for many years, as a result there are many fertilization experiments in diverse community types. A group of Long Term Ecological Research (LTER) network researchers founded PDT-Net (Productivity, Diversity &raits Network), to synthesize datasets from fertilization experiments in herbaceous communities across North America. Although responses to N addition were highly variable, several clear patterns emerged. We found that N addition increased productivity, reduced plant species diversity, and that plant species with particular functional traits (e.g. N-fixation ability, native and annual species) declined with fertilization, while others increased in dominance. Differences among responses of particular species common to several sites, as well as responses of species diversity in general, could be explained by differences in environmental context across sites. Finally, we found that fertilization altered community structure, by altering the distribution of species rank abundances, and by creating greater spatial heterogeneity. The dataset archived here contains relative abundances by species for ten sites (and many experiments within those sites) in control and fertilized plots. Species traits, productivity, and other environmental data are archived separately but link with this dataset.

title: Introduced Species Study

description: Data is continually being collected until the end of this study in December 2008. For each intertidal rocky and sandy site, we recorded upcoast and downcoast latitude and longititude, low-tide time and level, rugosity, swell, dominant substrate, beach angle, beach wrack presence, sediment coarseness, and profiles of each quadrat clearing (ex. horizontal, vertical, etc). In the event that quadrats or sandy cores were placed farther apart, a separate lat/long was recorded for those quadrats and cores. We also recorded non-native species found as well as had taxonomists in the field to provide complete species lists for the site. Site notes and photos were done at each site. For each subtidal site, we recorded latitude and longitude, time searched and depth range, rugosity, dominant substrate, surge, current, sediment appearance and profiles of each quadrate clearing and sandy core taken. Site notes were taken at each site as well as photographs of quadrat clearings when visibility allowed.

title: Datos climaticos Estacion Pico Espejo-MARS periodo 2004-2006

description: El conjunto de datos que se presenta en esta coleccion contiene informacion climatica registrada desde el 2004 hasta la actualidad. Los datos se registran, almacenan y transmiten cada minuto para los fines internos de investigacion y se transfieren a un servidor local cada hora, para la disposicion al publico. Estos datos son de importancia para la evaluaciÃ³n correcta de los resultados que se obtienen con los instrumentos del Proyecto MARS (Merida Atmospheric Research Station), pero tambien estan a disposiciÃ³n de cualquier instituciÃ³n interesada. Las variables actualmente registradas por la estaciÃ³n son: presion, temperatura, viento, humedad relativa, radiacion solar total y radiacion difusa. Los datos puestos a disposicion son datos crudos no validados tal como se reciben de la estacion.

title: Boreal Ecosystem-Atmosphere Study Project

description: The Boreal Ecosystem-Atmosphere Study (BOREAS) was a large-scale international interdisciplinary climate-ecosystem interaction experiment in the northern boreal forests of Canada. Its goal was to improve our understanding of the boreal forests -- how they interact with the atmosphere, how much CO2 they can store, and how climate change will affect them. BOREAS wanted to learn to use satellite data to monitor the forests, and to improve computer simulation and weather models so scientists can anticipate the effects of global change.

title: Barro Colorado Island 50 hectare forest dynamics plot data: 1980 - 2005

description: The 50 ha plot at Barro Colorado Island has 6 completed censuses: 1981-83, 1985, 1990, 1995, 2000, 2005. All trees &gt;=10 mm diameter at breast height were tagged, measured, mapped and identified to species. This site forms part of the Center for Tropical Forest Science (CTFS) network of large tropical forest plots in 14 countries, most ranging from 16 to 52 hectares.

title: Hawk Mountain Winter Bird Population Study

description: Like the Breeding Bird Census, the Winter Bird Population Study (WBPS) is a monitoring program that estimates winter bird densities in specific habitat types throughout North America. In addition, the vegetation of the plot is described. Relatively large areas of a single habitat are preferred for WBPS plots. Censusing methodology follows the Cornell Laboratory of Ornithology guidelines. Two permanent plots (the same two used in our BBCs), a ridge-top south-southwest facing 19.3 ha site in 120-130 year old oak-maple forest (elevation 408-448m), and a low elevation east-facing 16.9 ha site in 120-200 year old, oak-maple forest (elevation 265-347m), have been gridded at 30.5 m intervals in the Sanctuary's forest. The two sites are 750m apart. The habitat in each plot is characterized on a Habitat Classification Form supplied by the Cornell Laboratory of Ornithology. A detailed vegetation survey and vegetation mapping of each plot was conducted in 1989 (F. Watson, unpubl. data).

title: Arctic Ocean Invertebrate and POM Carbon and Nitrogen Isotope Dynamics

description: Carbon and Nitrogen Isotope Dynamics Biological material from three levels in the ocean (POM, plankton, benthos) was collected to determine the natural abundance of d13C and d15N. Isotope data were used to trace the advection of northward flowing organic material through the Bering Strait into the Chukchi and Bering Seas. Isotope signatures also provided information about the trophic links between pelagic and benthic components of the shelf and slope within the study area. Collections were made from USCG R/V Healy during two expeditions through the Bering, Chukchi, and eastern Beaufort Seas. The first 6-week expedition occurred from 15 May to 23 June 2004 (Spring) and the second from 16 July to 26 August 2002 (Summer).

title: Description and Data Archives of the University of Kansas Field Station (KUFS) Weather Station (1986-2008)

description: The University of Kansas Field Station (KUFS) acquired climate data from a single location, known as the Nelson Environmental Study Area (NESA), from 1986-2008. The weather station at NESA was set to sample eight atmospheric parameters (24 hours a day, 7 days a week) using a battery-powered datalogger. Raw data, data summeries, and complete metadata and documentation for the operation of the KUFS Weather Station at NESA are available. In August 2008, a new NRCS SCAN network weather station was installed adjacent to the KUFS weather station at NESA as its replacement.
