Species distribution modelling
Occurrence records and environmental layers are combined to estimate where a species can occur, with sampling bias corrected, absence data used where they exist and uncertainty mapped beside the prediction.
GCRI · Biodiversity Nexus
Ecology is the core science of this platform: it explains how species, populations and ecosystems respond to pressure, which changes matter for ecosystem function, and how losses become changes in the services people depend on. Field survey design and long-term monitoring give the evidence that every model is checked against.
Ecology studies the interactions among organisms and between organisms and their environment, from populations to ecosystems. It explains how 生物多样性丧失 and ecosystem change alter services such as pollination, water regulation and disease control. In biodiversity and nature, climate and hazards and oceans and coasts, ecological assessment identifies dependencies of agriculture, water and health on natural 系统. It supports nature-related disclosure and the evaluation of tipping-point risks. The canonical description is on STEM Commons.
Occurrence records and environmental layers are combined to estimate where a species can occur, with sampling bias corrected, absence data used where they exist and uncertainty mapped beside the prediction.
Repeated counts are modelled to separate trend from observation error, and viability analysis estimates how extinction risk changes under alternative management or habitat loss.
Water, soil or air samples are sequenced and sound recorders deployed to detect species that are hard to see, with detection probability estimated from replicate samples.

Assembled from the Nexus Standards area profile 生物多样性与自然风险标准: the hazards it names, the 系统 and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

Predictions are compared with independent survey data and long-term monitoring sites. Experimental manipulations and natural experiments test causal mechanisms.
| 核查 | 如何开展 |
|---|---|
| Independent survey validation | Distribution models are tested against survey data not used in fitting, held out in spatially separate blocks |
| Detection and observer effects | Occupancy and abundance models account for imperfect detection and changing observer effort |
| Taxonomic verification | Identifications are checked against reference collections and a taxonomic backbone before analysis |
| Sampling bias assessment | Record density is compared with access and effort so that gaps are not read as absence |
Ecosystems show nonlinear responses and thresholds that are hard to anticipate from past data. Sampling is uneven across regions and taxa.
The sectors ecology and biodiversity science touches and how strongly they depend on each other: what a study has to observe and model together.

A source is registered and assessed, its record labelled and classified, and a Digital Evidence Passport carries provenance; a correction reaches every dependent record.

No cycle has run and every programme is at service level R0. A gate is a programme decision, never a public-authority approval, certification or deployment authorisation.
