The 41 pages that link to Species, each with the reason it gives.

• IUCN Red ListNarrower topic: Species are the principal units assessed in the Red List.

• Carl LinnaeusRelated: Linnaeus’s system gave each classified species a stable two-part name.

• TaxonomyRelated: Species delimit the units that taxonomy names and groups.

• Endangered speciesNarrower topic: Risk assessments apply to defined species, though taxonomic boundaries can be contested.

• Linnaean taxonomyBroader topic: Linnaean naming assigns each classified organism to a named species.

• CultivarNarrower topic: A cultivar is a cultivated grouping within a species or, sometimes, across hybrid origins.

• RaceCompared with: Human racial categories are not equivalent to biological subdivisions such as species.

• Species DelimitationNarrower topic: Delimitation is the task of deciding which populations merit recognition as separate units of this kind.

• Taxonomic rankBroader topic: Species is generally the most specific standard rank in the main hierarchy.

• Cat breedNarrower topic: A breed is an intraspecific population, not a separate species.

• Species complexNarrower topic: A complex groups multiple putative species, so its boundaries depend on what counts as a species.

• TaxonBroader topic: Species is the lowest rank commonly used for naming taxa.

• Bird taxonomyRelated: Species are the principal units named and compared in bird taxonomy.

• Louis AgassizRelated: Agassiz regarded species as distinct, fixed units in his classification of life.

• Biological classificationBroader topic: Species are the units that classification groups into broader taxa.

• Natura 2000Narrower topic: Listed species are a central target of the network’s conservation measures.

• AllopolyploidyNarrower topic: The term distinguishes allopolyploid chromosome sets by their different species of origin.

• Common nameRelated: Many common names designate a species, but others cover several species or only part of one.

• Community (ecology)Narrower topic: Species identity determines which populations make up a community.

• EcocentrismRelated: Ecocentric ethics can value species as ecological lineages, not merely as resources.

• Snake identificationNarrower topic: Identification aims to assign an individual to a species, though species boundaries can be complex.

• Systema NaturaeRelated: Linnaeus’s naming system identifies species with distinctive two-part names.

• GenusBroader topic: Species are the principal units grouped together within a genus.

• OrganismRelated: Species classification organizes the diversity of organisms into named biological groups.

• John RayRelated: Ray helped define species by shared traits and the capacity to produce similar offspring.

• SubspeciesNarrower topic: Subspecies are named divisions within this broader taxonomic rank.

• Type speciesNarrower topic: The type species belongs to this rank, although the genus name is being anchored.

• CoywolfNarrower topic: Coywolf is not generally recognized as a distinct biological species.

• Family (biology)Broader topic: Species are grouped into genera, the immediate rank beneath family.

• Canid hybridRelated: Hybrid labels often depend on how the parental species are defined.

• Class (biology)Compared with: Species is a low-level unit, far more specific than class.

• Chrysalidocarpus lutescensNarrower topic: The name identifies one species rather than the many palms sold under overlapping common names.

• DalbergiaRelated: The genus contains numerous species with differing ranges and timber traits.

• Georges-Louis LeclercNarrower topic: Buffon treated reproductive continuity as a stronger guide to species than superficial resemblance.

• Gottfried Reinhold TreviranusRelated: Questions about the variety and transformation of species formed part of nineteenth-century biology.

• IdentificationRelated: Many identification tasks aim to decide which species a specimen belongs to.

• Kimura spiderNarrower topic: The unresolved question is which species, if any, this common name denotes.

• Northern storm petrelRelated: The family contains multiple species whose classification informs its boundaries.

• Order (taxonomy)Broader topic: Species lie several standard ranks below an order.

• PatagonaNarrower topic: Patagona is a genus-level grouping containing a living species.

• Ursid hybridRelated: The concept depends on distinguishing the parental bear species.
