Estimating Respiration Rates and Secondary Production of Macrobenthic Communities Across Coastal Habitats with Contrasting Structural Biodiversity

Invasions in Marine Communities: Contrasting Species Richness and Community Composition Across Habitats and Salinity

Whilemany studies of non-native species have examined either soft-bottom or hard-bottom marine communities, including artificial structures at docks andmarinas, formal comparisons across these habitat types are rare. The number of nonindigenous species (NIS) may differ among habitats, due to differences in species delivery (trade history) and susceptibility to invasions. In this study, we quant...

Biodiversity enhances ecosystem multifunctionality across trophic levels and habitats

The importance of biodiversity for the integrated functioning of ecosystems remains unclear because most evidence comes from analyses of biodiversity's effect on individual functions. Here we show that the effects of biodiversity on ecosystem function become more important as more functions are considered. We present the first systematic investigation of biodiversity's effect on ecosystem multi...

Bottom-Up Control of Macrobenthic Communities in a Guanotrophic Coastal System

Soft bottom macrobenthic communities were studied seasonally in three coastal ponds (Marinello ponds, Italy) at increasing distances from a gull (Larus michahellis) colony to investigate the effect of seabird-induced eutrophication (i.e. guanotrophication) on macrobenthic fauna. We hypothesized that enhanced nutrient concentration and organic load caused by guano input significantly alter the t...

Macrobenthic Community Structure, Secondary Production, and Rates of Bioturbation and Sedimentation at the Kiine'ohe Bay Lagoon Floor!

The Kane'ohe Bay lagoon floor is one of the largest shallowwater, muddy habitats in Hawai'i and is a major repository for sediments and, possibly, pollutants from the Kane'ohe watershed. Nonetheless, macrobenthic community structure, secondary production, and particle-mixing rates at the lagoon floor remain largely unstudied. During 1990-1991, we surveyed macrobenthic community structure at fou...
