habitat association

Edge evidence

• habitat causes habitat association biolink:causes

  The organism's primary habitat sets its habitat-association classification.

  • DOI:10.1038/nrmicro1341 Martiny et al. show habitat as a structuring axis of microbial biogeography.
• habitat association associated with biogeographic community structure biolink:associated_with

  Habitat-associated taxa display environment-specific community membership.

  • DOI:10.1038/nrmicro.2017.87 Fierer documents environment-specific community membership (e.g. the soil microbiome).
• habitat structures microbial community composition

  The habitat/environment selects for spatial variation in community composition.

  • DOI:10.1038/nrmicro1341 Free-living taxa exhibit biogeographic patterns; the environment selects for spatial variation in diversity (Martiny et al. review).
• environmental stress increases deterministic selection in community assembly RO:0002213

  Higher environmental stress increases the contribution of deterministic selection to assembly.

  • DOI:10.1038/s41564-023-01573-x Selection producing more dissimilar communities increased with stress (groundwater assembly study).
• environmental stress decreases ecological drift in community assembly RO:0002212

  Higher environmental stress decreases the contribution of stochastic drift to assembly.

  • DOI:10.1038/s41564-023-01573-x Drift showed negative correlation with stress; stochastic importance decreased with increasing environmental stress.
• environmental stress decreases dispersal limitation in community assembly RO:0002212

  Higher environmental stress decreases the contribution of dispersal limitation to assembly.

  • DOI:10.1038/s41564-023-01573-x Dispersal limitation showed negative correlations with stress.
• salinity structures microbial community composition

  Salinity is a primary abiotic regulator of aquatic community composition.

  • DOI:10.1186/s40168-024-01979-7 Lake microbiomes primarily regulated by salinity; saline vs freshwater lakes show distinct taxonomic profiles.
• salinity enriches osmolyte transport and synthesis genes

  Saline habitats enrich for osmolyte transport and synthesis genes.

  • DOI:10.1186/s40168-024-01979-7 Saline-lake microbiomes possess more genes encoding osmolyte transport and synthesis.
