“…Vegetation such as seagrasses can profoundly influence animal assemblages by modification of physical, chemical and biological processes within these habitats (Everett 1994, Webster et al 1998, Attrill et al 2000, van Houte-Howes et al 2004. For example, the physical presence of a plant canopy provides shelter and protection from predation for invertebrates and young fish (Summerson & Peterson 1984, Stoner & Lewis 1985, Edgar 1990, Boström & Bonsdorff 1997, De Almeida & Ruta 2000, Norkko et al 2000, Jackson et al 2001, Bloomfield & Gillanders 2005. Vegetation also influences localised water flow (Fonseca & Cahalan 1992, van Keulen & Borowitzka 2002, which changes the sedimentation rate and can enhance sediment organic/nutrient content and food availability for infaunal and epifaunal communities (Hull 1987, Reusch & Williams 1999.…”

Consequently, vegetated habitats such as seagrass beds are typically characterised by high primary production, species diversity and faunal abundances (Webster et al 1998, Bloomfield & Gillanders 2005.…”

Sargassum muticum is an invasive brown macroalga that originates from Japan. In the introduced range, thalli can grow in soft substratum habitats attached to embedded rock fragments and shells. Within Strangford Lough, Northern Ireland, S. muticum has rapidly colonised large areas of soft substrata, where dispersal by peripatetic or 'stone-walking' plants is very effective. Sediment cores were collected under and outside canopies of S. muticum in Strangford Lough (S. muticum first recorded there in 1995) and Langstone Harbour, English Channel (S. muticum first found there in 1974) to investigate modification of the infaunal assemblages. At both study sites, community analyses highlighted significant differences between the assemblages under the canopies and those in adjacent unvegetated areas. In Strangford Lough, the invertebrate community under the canopy contained a higher abundance of smaller, opportunistic, r-selected species than outside the canopy. By contrast, the communities under and outside the canopy at Langstone Harbour were similar in species composition, diversity and dominance, but overall faunal abundance was greater under the canopy. Sediment characteristics were not affected by S. muticum canopies, but the infaunal changes may be related to environmental modification; shading, flow suppression and temperature stratification were also investigated. The differences between these 2 sites indicate that localised conditions and/or the duration of colonisation of S. muticum are important in determining the nature of habitat modification.

“…Even though Spartina wetlands often provide poorer habitat quality than co-occurring seagrass for nursery-stage marine fauna (Minello et al 2003, Bloomfield & Gillanders 2005), here we found that Spartina is superior habitat to tropical mangrove vegetation. As such, mangrove expansion is likely to have a negative impact on Callinectes populations.…”

“…Seagrass beds function as important nurseries for larval and juvenile stages of fish and invertebrates (Beck et al, 2001;Bloomfield & Gillanders, 2005; Dorenbosch et al, 2005), particularly in patchy rather than homogenous seagrass meadows (Holt et al, 1983). In H. wrightii patches at Golfo La Perra and Corral de Mulas, we identified 22 macroinvertebrate species from three taxonomic groups (Crustaceans, Echinoderms, Molluscs) in three phyla (Table 1).…”

ABSTRACT. Seagrasses are aquatic angiosperms that grow submerged in shallow marine and estuarine environments worldwide. Halodule wrightii is a circumtropically distributed seagrass species found primarily in the Atlantic Ocean, but also in parts of the Indian Ocean and eastern Pacific Ocean. Along the Pacific coast of Central America, large swaths of the reported distribution of H. wrightii are assumptions based on interpolation between known seagrass point locations, and despite confirmation of H. wrightii occurrence in Bahía de Jiquilisco in El Salvador, little is known about its distribution and associated species, which can hamper efforts to conserve this seagrass ecosystem. To address these gaps in data, we provide the first assessment of H. wrightii distribution and associated macroinvertebrate species in Bahía de Jiquilisco. We identified six areas where seagrasses occurred and two of these were selected for monitoring. At the two sampled areas, heterogeneous patches of H. wrightii covered 27.1 km 2 with 22 associated macroinvertebrate species from three taxonomic groups in three phyla. We conclude by discussing local threats to H. wrightii, including implications for endangered hawksbill (Eretmochelys imbricata and green (Chelonia mydas agassizii) turtles that depend on these ecosystems, and describe opportunities for conservation in Bahía de Jiquilisco.
