Maps show the distribution and interannual variability of 64 Ecosystem Functional Types (EFTs) across the conterminous United States from 2001 to 2014. The dataset, produced by NASA, uses a 0.05-degree resolution time-series of MODIS Enhanced Vegetation Index (EVI) imagery to classify ecosystems based on functional traits. It provides spatial patterns of modal EFT and pixel-level variability without relying on prior vegetation type classifications.
Aerial Photo Interpretation mapping produced broad floristic types for the Upper North East NSW CRA region. The NPWS completed GIS products for this layer in 2001, using traditional API techniques on plastic overlays at scales of 1:25,000 and 1:50,000. The scanned and rectified digital dataset merges information compiled into 1:100,000 tiles across the project area.
Initial conditions for ionic concentrations in intracellular and extracellular domains. The values are based on four cited references, with some values reported with extra digits to ensure initial electroneutrality. The dataset is a 5.5 KB XLS file authored by Karoline Horgmo Jæger and last updated on 2026-05-28.
9.5 KB of parameter values used in biophysical simulations, authored by Karoline Horgmo Jæger and last updated on 2026-05-28. The data likely contains parameters for extracellular, membrane, and intracellular domains, with specific diffusion coefficients set for ions in the cell membrane and synaptic cleft.
Federica Palma's 16.3 KB Excel file discusses a unified strain taxonomy system for bacterial pathogens. The dataset likely contains information on Life Identification Number (LIN) codes, a proposed stable multilevel strain taxonomy. This resource, updated in June 2026, aims to address challenges in classification instability and nomenclature disconnection in core genome multilocus sequence typing.
A global dataset compiled from primary literature provides estimates of fine root biomass and specific area. The data supports studies on root property distributions and is associated with research papers from Jackson et al. in 1996 and 1997. It was compiled by NASA to aid in understanding ecosystem functions like carbon and water fluxes.
12 beagle dogs were used to evaluate electrospun gelatin/polycaprolactone nanofiber membranes for repairing full-thickness buccal mucosal defects, with a comparative study against acellular dermal matrix membranes. The dataset, authored by Kun Song and shared under a CC-BY-4.0 license, includes results from macroscopic observations and histological assessments at postoperative days 7, 14, and 28. It was last updated on 2026-05-25.
Fisheries and Oceans Canada researchers tested a non-destructive method for assessing clam populations by correlating siphon hole observations with actual clam presence, number, and size. Data includes clam abundance, biomass, size, and corresponding siphon hole metrics alongside environmental parameters like sediment grain size and seawater temperature. The dataset was collected at four sites in New Brunswick and Nova Scotia and was validated by multiple researchers prior to publication.
800 field plots inform vegetation community maps at 20 cm resolution for three landscapes near Toolik Lake, Alaska. The National Aeronautics and Space Administration created these maps using a Random Forest model with 2013 airborne lidar and imagery, validated by 2014-2015 field data. This dataset provides a detailed snapshot of northern foothills vegetation in the Brooks Range.
1.77 million square kilometers of the Central Amazon Basin were analyzed to produce monthly mean inundation areas for four distinct wetland cover classes from 1979 to 1996. This time-series data quantifies the extent of open water, river channels, macrophytes, and flooded forests, including calculations for the mainstem and its eastern and western halves. The dataset provides a foundational record for understanding the seasonal and interannual flood pulse dynamics of this critical ecosystem.
Research data from a study investigating the role of bacterial glutathione peroxidase in Pseudomonas aeruginosa virulence under hyperuricemic conditions. The dataset, authored by Jadye da Silva Cordeiro and last updated in May 2026, includes results from in vitro oxidant exposure and in vivo mouse infection models. Findings demonstrate that GPx detoxifies organic hydroperoxides, enhancing bacterial resistance to oxidative killing.
U.S. Pacific Northwest forests are analyzed through Biome-BGC modeled estimates of carbon stocks and fluxes from 1986 to 2010. The dataset includes mapped distributions of forest disturbances categorized by type (harvest, fire, pest/pathogen) and tabular summaries broken out by ownership and ecoregion. It was produced by the National Aeronautics and Space Administration and includes supporting climate data for 1980-2010.
Chaofang Sun published a dataset on figshare in June 2026, investigating legacy effects of senescent plant material on invasion success. The data, 111.8 KB in size, includes results from experiments using soils conditioned with healthy and diseased litter from 14 native species to examine impacts on invader Solidago canadensis and native competitor Artemisia scoparia. The study reveals coupled nutrient and disease pathways through which litter deposition promotes invasion.
NASA's NACP VPRM dataset provides optimized net ecosystem exchange parameters for 65 flux tower sites across North America. It includes parameters like basal respiration rate (beta), temperature sensitivity (alpha), and light-use efficiency (lambda) derived from eddy covariance, temperature, PAR, and satellite data. The data cover the conterminous USA, Alaska, and Canada from 2000 to 2006, aggregated by site, plant functional type, and temporal scale.
A study of 384 Lohmann Pink hens at 65 weeks old compared fasting-induced molting with zinc oxide supplementation. Serum, cecal contents, and ovaries were sampled across six stages from pre-molt to post-molt recovery. The dataset, last updated in May 2026, contains results showing accelerated cessation of lay and earlier recovery with high-zinc diets.
A dataset from a study comparing fasting-induced molting to zinc oxide supplementation in 384 Lohmann Pink hens. It includes serum, cecal, and ovarian samples across six stages from pre-molt to post-molt recovery, measuring physiological and production outcomes. The data was published by Ling Chang on figshare under a CC-BY-4.0 license.
Supplementary file 1_Multi-index analysis for wildfire severity and vegetation dieback assessment in semi-arid forest ecosystems.docx contains remote sensing analysis results from a study in the Ouled Yagoub State Forest, Algeria. The dataset, authored by Oussama Meghithi and shared on figshare under CC-BY-4.0, uses Landsat 8 OLI and Sentinel-2 imagery from 2019 to 2022 to assess wildfire impacts and vegetation decline. It employs ten spectral indices across themes of vegetation dynamics, burned-area severity, and forest dieback.
NASA's NPP Multi-Biome dataset provides site-level summary statistics from 125 intensive study sites across five major biomes: boreal forest, grassland, temperate forest, tropical forest, and tundra.
