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. |
