Genetic composition

The spatial and temporal variability in the intraspecific genetic composition.

EBV name EBV description
Intraspecific genetic diversity The variation in DNA sequences among individuals of the same species.
Genetic differentiation Divergence in genetic composition (identity and frequencies of alleles) among multiple populations.
Effective population size The number of individuals in an idealized population that will exhibit the same amount of genetic diversity loss as the population under consideration.
Inbreeding Mating between related individuals.

Species populations

The spatial and temporal variability in the distribution and abundance of species populations.

EBV name EBV description
Species distributions The species occurrence probability over contiguous spatial and temporal units addressing the global extent of a species group.
Species abundances Predicted count of individuals over contiguous spatial and temporal units addressing the global extent of a species group.

Species traits

Within-species variation in trait measurements along the axis of taxonomic diversity.

EBV name EBV description
Morphology The variation in physical attributes of organisms of the same species.
Physiology Chemical or physical functions promoting organism fitness and responses to environment.
Phenology Presence, absence, abundance or duration of seasonal activities of organisms.
Movement Behaviors related to the spatial mobility of organisms such as dispersal and migration routes.
Reproduction Sexual or asexual production of new individual organisms (‘offspring’) from parents. Examples: Age at maturity, number of offspring, lifetime reproductive output.

Community composition

The abundance and diversity of organisms making up ecosystems.

EBV name EBV description
Community abundance The abundance of organisms in ecological assemblages.
Taxonomic/phylogenetic diversity The diversity of species identities, and/or phylogenetic positions, of organisms in ecological assemblages.
Trait diversity The diversity of functional traits of organisms in ecological assemblages.
Interaction diversity The diversity and structure of multi-trophic interactions between organisms in ecological assemblages.

Ecosystem functioning

Attributes related to the performance of ecosystems that result from the collective activities of its organisms.

EBV name EBV description
Primary productivity The rate at which energy is transformed into organic matter primarily through photosynthesis.
Ecosystem phenology Duration and magnitude of cyclic processes observed at the ecosystem level, such as in vegetation activity, phytoplankton blooms, etc.
Ecosystem disturbances Abrupt deviances in the functioning of the ecosystem from its regular dynamics.

Ecosystem structure

The spatial arrangement of ecosystem units collectively defined by organisms forming these units.

EBV name EBV description
Live cover fraction The horizontal (or projected) fraction of area covered by living organisms, such as vegetation, macroalgae or live hard coral.
Ecosystem distribution The horizontal distribution of discrete ecosystem units.
Ecosystem Vertical Profile The vertical distribution of biomass in ecosystems, above and below the land surface.
