As an example, in the eelgrass beds of North Carolina, gastropods represented up to 72% of the total numbers of epifauna found in the ecosystem (Thayer et al.
Reports of the epifauna in this Bight substrate include most of the species noted in the above Coastal section.
On arrival at the laboratory, all non-barnacle epifauna were removed from both sides of barnacle substrates.
A combination of techniques was used at each site, including grab and box samples for infauna and sediments, and towed video for epifauna and general seafloor conditions, as described below.
Because bottom fishing can kill and injure benthic invertebrates that are either caught as bycatch or crushed underneath fishing gear, heavily fished areas often exhibit decreased abundance, biomass, and diversity of epifauna (Collie et al.
Bottom-fishing gear can reduce habitat complexity by removing emergent epifauna, smoothing sedimentary bedforms and by removing structure-forming species such as corals and sponges (Hutchings, 1990; Auster et al.
maxima taken by research drift divers in Western Australia ranges between less than 80 mm to ~250 into, providing evidence for ongoing recruitment, supported by the presence of 0+ and 1+ y classes (<35 and 40-80 mm, respectively) as epifauna on commercially harvested shell (Hart & Joll 2006).
Kingklip are piscivorous and were largely confined to holes at the base of rocks and favored areas without a conspicuous epifauna.
The heterogeneous 3-dimensional structures formed by oyster reefs provide settlement surfaces for epifauna and habitat for benthic organisms, serving as the base for a complex ecosystem (Wells 1961, Dame 1979, Kennedy 1996, Tolley & Volety 2005).
The epifauna were then carefully picked by hand from the net and preserved in 70% ethanol solution for identification and enumeration.
Bivalve tissue samples from whelk epifauna (12 mussels and 1 oyster) and whelk foot muscle tissue samples (ranging from 0.
Pacific oysters could influence local drill density by creating complex habitat structure (Crooks 2002) or via bottom-up pathways (drills consume oysters as well as oyster epifauna such as barnacles), which could lead to apparent competition (Holt & Lawton 1994) between Pacific and Olympia oysters.
