“…As pointed out by several authors, e.g. Wieser (1959), Novak (1982) and Hicks and Coull (1983), abundances and diversity of meiofauna of marine vegetation are positively correlated with habitat complexity and negatively correlated with water movements, which is confirmed by this study.…”

“…The macrophytodetritus accumulations harboured the same density in order of magnitude (10 4 -10 5 indiv. m −2 ) as P. oceanica meadows (Mascart et al, 2013;Novak, 1982). The diversity, around 30 to 50 harpacticoid species, was similar to other phytal ecosystems (De Troch et al, 2008;Heip et al, 1983;Hicks, 1977;Johnson and Scheibling, 1987;Steinarsdóttir et al, 2003).…”

“…The most abundant species in the macrophytodetritus accumulations were also commonly found in adjacent habitats (Hicks and Coull, 1983;Mascart et al, 2013;Novak, 1982). Colonisation by invertebrates is rapid, however, it is limited in its extent and magnitude (Norkko and Bonsdorff, 1996;Palmer, 1988).…”

The overall aim of this study was (1) to assess the diversity and density of meiofauna taxa, especially harpacticoid copepod species, present within accumulated seagrass macrophytodetritus on unvegetated sand patches and (2) to elucidate the community structure of detritus-associated harpacticoid copepods in relation to natural temporal variability of physico-chemical characteristics of accumulations. This was investigated in a Posidonia oceanica (L.) Delile seagrass ecosystem in the northwest Mediterranean Sea (Bay of Calvi, Corsica, 42°35′N, 8°43′E) using a triplicate macrophytodetritus core field sampling in two contrasting sites over the four seasons of 2011. Meiofauna higher taxa consisted of 50% Copepoda, of which 87% belonged to the Harpacticoida order. Nematoda was the second most abundant taxa. The copepod community displayed a wide variety of morphologically similar and ecologically different species (i.e. mesopsammic, phytal, phytal-swimmers, planktonic and parasitic). The harpacticoid copepod community followed a strong seasonal pattern with highest abundances and species diversity in May-August, revealing a link with the leaf litter epiphyte primary production cycle. Aside from the important role in sheltering, housing and feeding potential of macrophytodetritus, a harpacticoid community BEST analysis demonstrated a positive correlation with habitat complexity and a negative correlation with water movements and P. oceanica leaf litter accumulation.

“…Because of its high productivity, Posidonia oceanica represents an important food substrate for many marine organisms (NovAK 1982;PI:Rc 1985). The productivity is different in the various Mediterranean areas due to the sensitivity of the plants to changing local and temporal factors of its environment (GIACCONE et al 1981).…”

Harpacticoid copepods inhabiting a seagrass (Zostera marina L.) bed on Roberts Bank, British Columbia, Canada, were sampled every 2 wk from late January to mid July in 1986 and 1987. Samples were taken of seagrass leaves and the underlying sediment. The epiphytic copepod community at this study site was composed of typical temperate genera (e.g. Dactylopodia, Harpacticus, Mesochra, Tisbe, Zaus). Total copepod abundance on the leaves generally exceeded that in the sediment. Densities on seagrass leaves were markedly lower in 1987 than in 1986. Temporal patterns of abundance of individual species were different between years, contrasting with the stability of successional patterns in sediment-dwelling harpacticoid communities. Some seagrass-dwelling copepod populations may be seeded in the spring from sediment-dwelling individuals. Also, possible movement from the leaf surface to the sediment was observed for 1 species. This study underscores the importance of sampling multiple subhabitats in seagrass beds when assessing the dynamics of the epiphytic copepod community.
