Extracellular enzyme activities in the Maumee and Ottawa Rivers (OH) from 1994 to 1995

Duke University Biology Department & Robert Sinsabaugh
The data include estimates of bacterial production and apparent Vmax (a measure of catalytic capacity) and apparent Km (a measure of available substrate concentration) for six extracellular enzymes (alpha-glucosidase, beta-glucosidase, aminopeptidase, protease, phosphatase, acetyl esterase) measured in the Maumee and Ottawa Rivers of Ohio (USA). The purpose of the dataset was to integrate the effects of temperature and resource availability on bacterial production using metabolic scaling theory and the kinetics of EEA.

Data and analyses for Hooper et al. (2012) Nature, �A global synthesis reveals biodiversity loss as a major driver of ecosystem change�, DOI: 10.1038/nature11118.

NCEAS 12560: Cardinale: Biodiversity And The Functioning Of Ecosystems: Translating Results From Model Experiments Into Functional Reality, National Center For Ecological Analysis And Synthesis & Dave Hooper
Many experiments have shown that species loss can alter key processes important to the productivity and sustainability of Earth�s ecosystems. However, it is unclear how these effects compare to the direct effects of other forms of environmental change that are both driving diversity loss and altering ecosystem function. We used a suite of meta-analyses of published data to show that the impacts of species loss on productivity and decomposition - two processes important in all...

Birds of the University of Kansas Field Station

University Of Kansas Field Station & Galen Pittman
This checklist is intended to provide an overview of the avifauna of KUFS. Two hundred thirty-seven bird species have been recorded on University of Kansas Field Station (KUFS) lands from 1948 to present. Eighty-eight of these species are confirmed breeding birds and another eight are probable breeders.

Growth of five species of trees on experimental plots on sand tailings left after mining for rutile in Sierra Leone

Data consists of the height of five species of trees after 2.5 years of growth; the five species are: â ¢ Gmelina (Gmelina arborea), â ¢ mango (Mangifera indica), â ¢ cashew (Anacardium occidentale), â ¢ citrus (Citrus sinensis) and â ¢ monkey apple (Anisophyllea laurina). Trees were planted on the sand tailings which consit of a very coarse quartz sand (silts and clays are dumped separetly during the processing of the rutile in the...

Biophysical Observations Aboard Alaska Marine Highway System Ferry: Tustumena, Gulf of Alaska (2004-2008)

Edward D. Cokelet
An oceanographic measurement system aboard the Alaskan ferry Tustumena operated for four years in the Alaska Coastal Current with funding from the Exxon Valdez Oil Spill Trustee Council, the North Pacific Research Board and the National Oceanic and Atmospheric Administration. Sampling water from the sea chest of the ship at 4m, the underway system measured: (1) temperature and salinity: basic physical variables, (2) nitrate: an essential phytoplankton nutrient, (3) chlorophyll fluorescence: an indicator of phytoplankton...

McKenzie, Lianne C. Ball, Michael C. Runge and ,Helen M. Alexander. (2011). An adaptive decision framework for the conservation of a threatened plant. Journal of Fish and Wildlife Management. In press.) The following description is modified from the Moore et al. (2011) abstract:...

Individual-based food web (Guadalquivir estuary, southern Spain)

Instituto De Ciencias Marinas De Andalucia & Pilar Drake
Stomach contents and estimates of abundance were collected monthly from February 1998 to January 1999 at three locations in the estuary of the Guadalquivir river, southern Spain. Samples were taken across a range of different environmental conditions, with seasonal variations in temperature and spatial variations in salinity.

Field voles and microparasite data

University Of Liverpool & Mike Begon
 May 2001 - March 2007. Four field vole populations trapped every 28 days (March-November) or every 56 days (November-March), using a 0.3ha grid at grassy sites within a man-made spruce forest, Kielder Forest, UK, (55o13&rsquoN, 2o33&rsquoW). The data set consists of 14,075 captures of 5,981 individual voles. Individuals were identified using subcutaneous microchip transponders. Each time an animal was trapped, data were collected on mass, reproductive condition, and numbers of ticks and fleas. Parasite...

invertebrates in aquatic plants in the Hudson River

Cary Institute Of Ecosystem Studies & David Strayer
These are data on macroinvertebrates living in beds of Trapa natans (an exotic plant) and Vallisneria americana (a native plant) in the freshwater tidal Hudson River in eastern New York in the year 2000. The data include both animals living on the plants and animals living in the sediments beneath the plants.

Multi-decade population studies of Michigan old-growth forests

NCEAS 12218: Woods: Slow Systems And Complex Data-Sets: Multi-Decade Permanent Plots Permit Address Of Recalcitrant Questions About Late-Successional Forests, National Center For Ecological Analysis And Synthesis & Kerry Woods
Established in 1935, a regular grid of 256 permanent plots includes about 20% of a 100-ha old-growth forest at the Dukes Research Natural Area in northern Michigan, USA. Woody stems have been remeasured 3�7 times providing extensive quantitative records of population and community dynamics over periods of up to 72 years. Woody stems in upland hemlock�northern hardwood stands, about half of the study plots, have been mapped and individually tracked since about 1990. Remaining plots...

Hydrologic modeling of the Baltimore region

Baltimore County University Of Maryland & Aditi Bhaskar
We applied a coupled hydrologic model (ParFlow) to the Baltimore metropolitan area to examine the impacts of urban development. The urban features we studied include reduced vegetative cover, impervious surface cover, infiltration and inflow (I&I) of groundwater and stormwater into wastewater pipes, and other anthropogenic recharge and discharge fluxes including water supply pipe leakage and well and reservoir withdrawals. We compared the base case (all four features) to simulations in which an individual urban feature...

Workshop on Establishing a Greenland Ice Sheet Ocean Observing System (GriOOS), 2015

Fiammetta Straneo, Twila Moon, Dave Sutherland, Patrick Heimach & Ginny Catania
The need to establish a Greenland Ice Sheet Ocean Observing System (GriOOS), as a means of providing long-term data at a number of key sites around Greenland that can inform understanding and provide boundary conditions and validation for models, was discussed at an International workshop held in San Francisco, on December 12-13, 2015. The workshop was attended by 47 participants from the USA, Canada, Greenland, Denmark, Norway, United Kingdom and Japan covering a wide range...
