Eutrophication is a serious threat to aquatic ecosystems globally with pronounced negative effects in the Baltic and other semi-enclosed estuaries regional seas, where algal growth associated excess nutrients causes widespread oxygen free "dead zones" threats sustainability. Decades of policy initiatives reduce external (land-based atmospheric) nutrient loads have so far failed control Sea eutrophication, which compounded by significant internal release legacy phosphorus (P) biological...

Abstract Predictive species distribution models are mostly based on statistical dependence between environmental and distributional data therefore may fail to account for physiological limits biological interactions that fundamental when modelling distributions under future climate conditions. Here, we developed a state-of-the-art method integrating theory with survey experimental in way allows us explicitly model both physical tolerance of inherent natural variability regional conditions...

Abstract For many coastal areas including the Baltic Sea, ambitious nutrient abatement goals have been set to curb eutrophication, but benefits of such measures were normally not studied in light anticipated climate change. To project likely responses on eelgrass ( Zostera marina ), we coupled a species distribution model with biogeochemical model, obtaining future water turbidity, and wave for predicting hydrodynamics area. Using this, was modeled different combinations scenarios wind...

In shallow vegetated aquatic habitats exceeding 2 m depth, conventional methods to determine fish abundances are of limited success. this study, the sampling qualities for investigating community associated with eelgrass Zostera marina were tested: a newly developed enclosure drop trap (ET) operated from water surface and visual diving strip transect technique. The construction procedure described in detail. Both procedures performed simultaneously at same site depths between 5 m. comparison...
