Four contrasting tundra vegetation types were studied near Toolik Lake, Alaska, in 1982. Living above- and below-ground biomass was sampled three times during the growing season using quadrats ranging from 10 cm x 20 cm to 50 cm x 50 cm. The dataset includes measurements of net primary production components, biomass, elemental content of above-ground samples, and leaf area index.
Thirty-two quaking aspen and thirty-one black spruce sites in the boreal forest were studied to measure forest stand characteristics for remote sensing validation and ecology. The dataset provides counts of canopy and subcanopy tree species, with measurements including diameter breast height (dbh), tree height, and crown depth derived from triangulation. For aspen sites, it also includes visual estimates of percent vegetation coverage across canopy, subcanopy, and understory strata.
Soil surface carbon dioxide flux can be a major, non-negligible component of a grassland's carbon budget. This dataset contains measurements from the FIFE study area, using a prototype gas exchange system to characterize CO2 flux alongside critical parameters like soil temperature, moisture, and leaf area index. The results demonstrate a soil chamber method for estimating fluxes, linking them to plant contributions via root respiration.
A 1.6 MB PDF review article authored by Chenyang Liu, last updated on May 22, 2026. It synthesizes findings from PubMed, Web of Science, and Scopus up to March 2026 to explain the gut-bone axis and novel microbiota-targeted therapeutic strategies.
NASA's MEaSUREs Vegetation Continuous Fields (VCF) Version 1 provides global fractional vegetation cover at 0.05 degree (5,600 meter) spatial resolution for yearly intervals from 1982 to 2016. The data product is derived from a bagged linear model algorithm using Advanced Very High Resolution Radiometer (AVHRR) observations compiled in the Long Term Data Record Version 4. It includes three bands for percent tree cover, non-tree vegetation, and bare ground, with a water mask applied.
A hierarchical classification tool developed by the Quebec Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks in 2024 to document conservation actions. The classification was refined from international standards with numerous partners to provide a more precise and practical tool for monitoring biodiversity initiatives. It is intended for government partners and conservation organizations.
39 threatened native vegetation communities are mapped across Tasmania in this state-wide layer. The Tasmanian Vegetation Monitoring and Mapping Program produced TNVC 2025, largely derived from TASVEG 5.0, as the fourth major release version. It replaces the previous TNVC 2020 layer.
Over 3000 km2 of seafloor imagery was collected aboard the RVIB Nathaniel B Palmer during the NBP14-02 expedition from 29 January to 16 March 2014. The Australian Ocean Data Network provides this data, captured using a 'yoyo' camera system with a 10.2-megapixel digital still camera and strobe, imaging approximately 4.8 m2 per shot. Still images have been analyzed for seafloor habitats and are hosted by the National Computing Infrastructure.
Jie Wang's dataset from figshare, last updated May 14, 2026, investigates the cascading effects of cadmium contamination on a tomato plant, western flower thrips, and minute pirate bug predator system. The 74.0 KB XLSX file contains results from analyses of plant photosynthetic physiology, untargeted metabolomics, and insect fitness, behavior, and cadmium accumulation. The study quantifies reductions in photosynthesis, insect survival, predation rates, and cadmium transfer through the food chain.
A 2026 study by Glenn T. Schumacher provides length and weight data for sampled Arctic Charr and Brook Trout. The dataset supports an analysis of ontogenetic niche shifts using eye lens stable isotope analysis in four lakes in Maine, USA. It is published under a CC-BY-4.0 license on figshare.
A 5.5 KB Excel dataset by Glenn T. Schumacher, last updated May 15, 2026, contains Bayesian hierarchical linear regression results from an eye lens stable isotope analysis study. The research examined ontogenetic niche shifts in Arctic Charr and Brook Trout populations across four lakes in Maine, USA, to assess differential vulnerability to environmental change.
Initial model setups for an agent-based model named MEET-eaters, which explores two-way interactions between supermarket supply and household demand for meal choices. The model, developed by Christa Blokhuis and reviewed with experts, simulates supply scenarios and interventions to shift diets towards more plant-based consumption. The dataset is 5.5 KB in size and was last updated on May 22, 2026.
MEET-eaters is an agent-based model exploring two-way interactions between supermarket supply and household meal choices in the Dutch context. The 5.5 KB dataset contains expert review inputs for the model, authored by Christa Blokhuis and last updated in May 2026. It was developed to test interventions targeting consumer preference or supermarket supply to shift diets from animal-based to plant-based options.
5.5 KB of model setup data from the MEET-eaters agent-based model, representing supermarkets, households, and consumers. The dataset, authored by Christa Blokhuis and last updated in May 2026, was developed to explore two-way interactions between supermarket supply and household demand for plant-based and animal-based meals within the Dutch socio-cultural context.
MEET-eaters is an agent-based model exploring two-way interactions between supermarket supply and household meal demand in the Dutch context. The 5.5 KB dataset contains simulation results from Christa Blokhuis, last updated in May 2026, testing interventions on consumer preference and supermarket supply. Results indicate supply and demand both strongly influence meal choice, with long-term policies required for a sustained dietary shift.
Christa Blokhuis published a 5.5 KB Excel dataset on figshare in May 2026. The data contains a summary of OFAT-based sensitivity analysis for the MEET-eaters agent-based model. The model explores interactions between supermarket supply and household demand for meals within the Dutch socio-cultural context.
Environment Agency data segments England's rivers into environmentally homogenous reaches for natural capital assessment. The network is derived from points every 500m, which defines the resolution limit for features like lakes. This river asset baseline supports an England-wide geospatial evidence base for environmental planning and delivery.
A fishery-independent acoustic survey initiated in 2015 provides an abundance index for herring stock assessment in NAFO Division 4T. The survey, a partnership between Fisheries and Oceans Canada and fishery associations, uses random parallel transects within predefined strata to estimate nightly spawning biomass. Data includes size and age measurements, acoustic tracking, and species counts.
James Nankivell's supplementary data supports a taxonomic reassignment of Australian sea snakes. The dataset includes morphological data from 51 examined museum specimens and collated data from 55 published individuals. It was last updated on May 12, 2026, and is licensed under CC-BY-4.0.
Genome assembly and annotation files from a pan-genome study of the mycoheterotrophic orchid Gastrodia elata. The dataset includes sequences and annotations for dark-red G. elata and re-annotated data from a 2022 reference genome, totaling 2.5 GB.
