- Abstract
Marine spatial planning and ecosystem-based management involves different methods of assessing the quality of habitats. The increase of information on spatial environmental parameters triggered the application of different species distribution models in benthic ecology. In this study empirical modelling is being used for the assessment of benthic habitat quality in aquatic ecosystems. A comparative analysis of four species distribution modelling methods (generalized additive models, multivariate adaptive regression splines, maximum entropy and random forests) was performed for predictions of the occurrence and biomass distribution of 23 macrozoobenthos species in Lithuanian marine area. These models, together with data on fish diet, were integrated in the system for the benthic habitat quality assessment in terms of food provision for Baltic cod, European flounder and eelpout. Also, biological valorisation of Lithuanian marine area was performed based on species traits, species richness, rarity of habitats and the status of benthic communities. Empirical modelling based on video survey data was applied for the assessment of the habitat alteration range caused by invasive bivalve Dreissena polymorpha.
