Variation in the trophic structure and species composition of some invertebrate communities in polluted kelp forests in the North Sea

Influence of sewage pollution on a rocky intertidal community dominated by the mytilid Brachidontes rodriguezi

“…Whereas most previous investigations describe sewage impact on communities dominated by macrophytes (Borowitzka 1972, Jones 1973, Munda 1974, 1980a, b , 1982, Littler & Murray 1975 or on infaunal soft bottoms (Marcotte & Coull 1974, Anger 1975a, b, Leppakoski 1975, Mearns & Word 1982, the present study deals with an epilithic community dominated by mytilid bivalves. Although low diversity and specific richness in the neighbourhood of the outfall could be predicted on the basis of previous studies, the decrease in diversity observed in transects located away from the outfall (200 and 250 m) was unexpected.…”

Potential novel habitat created by holdfasts from cultivated Laminaria digitata: assessing the macroinvertebrate assemblages

“…Change in habitat from benthic to suspended has many associated changes which could all cause variations in faunal communities. Changes in abiotic conditions, such as hydrodynamic environment (Moore 1972), sedimentation rates (Schaal et al 2012), depth (Coleman et al 2007), salinity (Jones 1973), oxygen availability (Scarratt 1961) and temperature (Scarratt 1961) are all associated with changes in kelp fauna. These factors could be measured relatively easily in the field to determine their degree of influence on suspended communities.…”

“…(3) Finally, cultivated kelp are suspended from ropes in the water column; this will alter both the hydrodynamic environment (discussed as an influence on epifauna by Moore 1972) and the accumulation of sediments thought to provide the bulk of carbon supply to the associated species (Schaal et al 2012). Changing from a benthic to a suspended growth form may also alter the environmental conditions experienced by kelp epifauna: changes in depth (Coleman et al 2007), salinity (Jones 1973), oxygen availability (Scarratt 1961), and temperature (Scarratt 1961). Ecological processes may also be altered between benthic and suspended growth forms.…”

Invertebrate communities in holdfasts of the kelp Macrocystis pyrifera from southern Chile

“…Only occasionally have the ecological interactions of the invertebrate communities occurring in the holdfasts been analysed or even described (Jones, 1971(Jones, , 1972(Jones, , 1973Moore, 1972Moore, , 1973bMoore, , c, 1974Moore, , 1978. The knowledge of the fauna inhabiting holdfasts of Macrocystis pyrifera is not a n exception to this trend.…”
