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.

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 kehilangan keanekaragaman hayati 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 sistem. 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.

Predictions are compared with independent survey data and long-term monitoring sites. Experimental manipulations and natural experiments test causal mechanisms.
| Pemeriksaan | Cara pelaksanaannya |
|---|---|
| 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.
