  • Given that sediment grain size is a major delimiter of infaunal distribution, there should be a clear linkage of structural vegetation to below-SWI biodiversity and composition.
  • infaunal species

Examples

  • This raises the intriguing question of whether there are fundamental differences in the effects of above-SWI versus infaunal predators on sedimentary biodiversity.

    Academic text (2000)
  • Benthic infaunal species also aggregate, possibly because detritus distribution is not uniform or because different types of detritus might attract different types of species.

    Academic text (2000)
  • No studies have been designed to test whether the diversity of these predators is significant for infaunal communities.

    Academic text (2000)
  • Interestingly, most of what we know about predation is from studies of above-sediment species, rather than interactions among infaunal species.

    Academic text (2000)
  • Before hypoxia, a mature assemblage of diverse infaunal and epifaunal species lives in the community (successional stage III).

    Academic text (2000)
  • Simple removal of these major predators is likely to alter infaunal biodiversity, in some cases increasing species richness (Peterson 1979, Reise 1985).

    Academic text (2000)
  • Infaunal grazers on seedlings and root structures can also regulate mangrove distributions (see Tomlinson 1986).

    Academic text (2000)
  • The infaunal organisms burrow deeply into the ocean floor, creating habitats for other marine life.

  • Researchers study infaunal communities to understand their role in the marine ecosystem.

  • Infaunal species play a crucial part in nutrient cycling within sediments by breaking down organic matter.

Morphology

infaunal = faunal (semi-transparent) = in + fauna + al

The word is regularly formed from 'faunal' with the prefix 'in-' meaning 'within', so the structure is clear even though the term is technical.

Etymology

Infaunal breaks into two parts: in- meaning 'in' or 'within' and fauna meaning 'animals'. So infaunal describes animals that live inside the sea or lake bed, like clams that bury themselves in the sand.
