Positive indirect effects of reef fishes on kelp performance: the importance of mesograzers.
It has been suggested that microcarnivorous reef fishes may play an important role in giant kelp forest communities by preventing infestations of mesograzers that could severely impact or potentially destroy recovering kelp forests after extreme disturbance events. However, these trophic linkages, specifically the direct and indirect effects of fishes on the biomass of mesograzers, grazing inte...
متن کاملQuantitative Assessment of Different Artificial Reef Designs in Mitigating Losses to Kelp Forest Fishes
Determining the success of artificial reefs as a tool for mitigating human-induced losses to fish populations requires explicit standards for performance assessment, and a robust monitoring program designed to collect the information necessary to evaluate those standards. Here we describe: (1) the biological performance standards established for kelp forest fishes on an artificial reef designed...
متن کاملWhat is the impact of kelp forest density and/or area on fisheries?
Background: Kelp forests are highly productive ecosystem engineers of rocky cold-water marine coastlines, providing shelter, habitat and food for a variety of associated organisms. Several factors have been related with an observed trend of kelp deforestation in some regions of the globe. The effect of this trend on fisheries has been poorly studied. The European directives addressing the conse...
متن کاملNearshore Pelagic Microbial Community Abundance Affects Recruitment Success of Giant Kelp, Macrocystis pyrifera
Marine microbes mediate key ecological processes in kelp forest ecosystems and interact with macroalgae. Pelagic and biofilm-associated microbes interact with macroalgal propagules at multiple stages of recruitment, yet these interactions have not been described for Macrocystis pyrifera. Here we investigate the influence of microbes from coastal environments on recruitment of giant kelp, M. pyr...
متن کاملFitting of two benthic fishes abundance Paracobitis hircanica and Neogobius fluviatilis Using Fuzzy Regression
Knowledge of biological requirements of aquatic organisms in perennial rivers is necessary for protection of biological diversity in riverine ecosystems. Habitat knowledge includes using models for estimating specific properties from physical structure of rivers by simple and accurate methods. Fuzzy regression model was investigated for two common endemic and benthic fishes, Paracobitis hircani...
