A research document describing a study on the probiotic Faecalibacterium prausnitzii and its role in sepsis-induced acute lung injury. The study used 16S rRNA sequencing and metabolomics on patient and murine model data to investigate the gut-lung axis. The document was authored by Xiaoli Feng and uploaded to figshare in May 2026 under a CC-BY-4.0 license.
Over 60 intensive study sites provide detailed biomass dynamics, climate, and site-characteristics data, with a majority being grasslands and the remainder tropical forests, boreal forests, and tundra. More than 1700 additional sites offer georeferenced NPP estimates, typically including latitude, longitude, and vegetation type. The compilation uses consistent, well-documented methods to estimate Net Primary Productivity from field measurements.
SWECON Project data provides stand characteristics, biomass, and production allocation for young and old-growth Scots pine forests near Jädraås, Sweden. Measurements from destructive and non-destructive methods were collected between 1973 and 1983, with accompanying climate data from 1974 through 1990. The dataset includes specific estimates for components like net primary production, litterfall, and root growth.
Updated palaeogeographic maps present alternative tectonic reconstructions for the northern margins of the Australian plate. The report, published by the Australian Ocean Data Network, details the tectonostratigraphic evolution from the Carboniferous to the Holocene. The models incorporate configurations for microplates like the Greater Birds Head and describe phases of rifting, sedimentation, and orogeny.
A palaeoecological record from lake sediment cores in Panama's Veraguas Province, spanning the Late Pleistocene to the Holocene. The data includes stratigraphy, radiocarbon-dated chronology, spores of coprophilous fungi, pollen, and charcoal. It was collected for PhD research funded by UKRI and is intended for publication in Quaternary Science Reviews.
NASA and the CABARE research program provide digital maps of surface parameters for a 5x5 degree region in Rondonia, Brazil. The dataset includes elevation, soil classification, sand and clay content, and two vegetation classifications from RADAMBRASIL and LANDSAT (1993-1994). This mapping work supported mesoscale meteorological modeling in forested and deforested Southwestern Amazonia.
SAFARI 2000 Land Cover from AVHRR, 1-Deg, 1987 is a southern African subset of a global land cover classification product. The dataset is based on Advanced Very High Resolution Radiometer (AVHRR) data from 1987, processed to a one-degree resolution and classified into eleven cover types representing major world biomes. It provides a coarse-resolution, supervised classification of vegetation and land cover for the region.
Fisheries and Oceans Canada and the Magdalen Islands ZIP Committee produced this dataset by interviewing experienced fishermen between January and April 2024. The resulting 16 vector layers map four types of herring observations across four distinct time periods, from before 1996 to 2021. Polygons are classified by the number of fishermen reporting each location, indicating the relative importance of areas over time.
Southern African biogenic volatile organic compound (BVOC) emissions were measured at flux tower sites in Maun, Botswana and Skukuza, South Africa during the 2001 wet season campaign. The dataset includes flux measurements from two ecosystems, species-level isoprene emission screening for 95 African plant species, and concurrent meteorological and CO2 data. It was collected by NASA investigators to support the development of a regional BVOC emissions model.
February 2001 measurements capture leaf-level biogenic volatile organic compound emissions from the dominant tree species Colophospermum mopane and other vegetation near Maun, Botswana. This dataset, collected as part of the SAFARI 2000 initiative, includes emission rates, physical leaf measurements, and controlled environmental parameters from a LI-COR leaf cuvette. The National Aeronautics and Space Administration is the listed organization for this data.
Experimental burns in Zambia's Western Province during August and September 2000 provide data for analyzing fire impacts in dambo grasslands and miombo woodlands. This dataset contains three measurement sets: field spectroradiometer reflectance along transects and plots, leaf reflectance/transmittance for three tree species, and calculations integrating biomass with Landsat-equivalent reflectance to estimate combustion completeness. The data is stored in CSV files, with detailed methodology in a companion PDF.
Australian Ocean Data Network hosts a geological study on the long-term landscape evolution of Groote Eylandt. The description argues the Cretaceous marine transgression was the most significant event, altering drainage and preserving a pre-Cretaceous landscape form with minimal escarpment retreat. The dataset was last updated on 2026-06-04.
A geological bulletin summarizes regional mapping results from 1961 to 1967 over an area of 67,000 km² near Townsville. The work was conducted by teams from the Bureau of Mineral Resources and the Geological Survey of Queensland. It details the geological evolution from the Precambrian or Cambrian through to the Cainozoic, covering major structural events, sedimentary basins, and economic geology.
The Koonamore Vegetation Reserve (KVR) dataset contains long-term vegetation monitoring records, including fixed photopoints, from a 400-hectare protected area in arid South Australia. Established in 1925 by Professor TGB Osborn, the project studies vegetation recovery after the removal of grazing pressure. The monitoring series is over 80 years old, making it one of the longest-running of its type globally.
February 23 to September 18, 2022, this dataset contains field photographs from vegetation sampling plots during NASA's SHIFT campaign. It provides visual ground reference data collected concurrently with weekly AVIRIS-NG airborne spectrometer flights over three California reserves. The imagery supports validation and analysis of spectral data for terrestrial ecosystem studies.
Australia's Commonwealth waters include a network of 58 marine parks covering 3.3 million square kilometres. This dataset provides a 30-meter resolution bathymetry grid for the Gifford Marine Park, compiled from Geoscience Australia's holdings and processed with a hillshade image. The data supports the development of 'eco-narrative' documents for park management.
A longitudinal pilot study tracks gut microbiota changes in a single participant switching from a Western diet to a 12-week Indigenous Arctic animal-based diet. The dataset includes 29 fecal samples analyzed via 16S rRNA gene sequencing, measuring diversity metrics and taxonomic composition. The data was published by Mads B. W. Bjørnsen under a CC-BY-4.0 license.
A longitudinal pilot study tracks gut microbiota changes in a single participant switching from a Western diet to an Indigenous Arctic diet. The dataset includes 29 fecal samples analyzed via 16S rRNA gene sequencing, profiling bacterial community composition. The study was authored by Mads B. W. Bjørnsen and last updated on 2026-05-21.
29 fecal samples were collected from a single participant before, during, and after a 12-week dietary intervention switching from a Western to an Indigenous Arctic diet. The data, generated via 16S rRNA gene sequencing and analyzed for diversity metrics and taxonomic composition, was authored by Mads B. W. Bjørnsen and published on figshare in 2026. The study provides preliminary evidence of significant gut microbiota restructuring linked to the dietary change.
A longitudinal pilot study of gut microbiota dynamics during a dietary transition from a Western to an Indigenous Arctic animal-based diet. The dataset includes 29 fecal samples analyzed via 16S rRNA gene sequencing, profiling bacterial community shifts. The study was authored by Mads B. W. Bjørnsen and published on figshare under a CC-BY-4.0 license.
