Estuarine intertidal mudflats play a crucial role in the remineralization of organic matter, nutrient recycling, and filtration pollutants nutrients from terrestrial sources. Despite their importance, global extent is decreasing due to range direct indirect anthropogenic stressors. This thesis was motivated by urgent need expand our understanding present state biogeochemical dynamics mudflats. Our primary aim determine which contribute estuarine retention how this contribution influenced seasonal fluctuations biological activity. Furthermore, we sought understand potential modifications that may occur functioning as resulting sand starvation increased sediment resuspension. Since subtidal areas experience distinct daily dynamics, it necessary different processes occurring each zone.

Introduction The importance of the response-effect trait dichotomy in marine benthic ecology has garnered recent attention. Response traits, characterising species responses to environmental variations, have been a dominant focus development ecological indicators for ecosystem health assessment. In contrast, effect expressing effects organism activities on ecosystem, still do not benefit from an equal interest spite complementary facet that they provide complete our understanding functional diversity and vulnerability. this study, we explore consequences disturbance by bottom trawl fisheries composition. Methods To end, used different contexts trawling conditions thirteen case studies European waters apply same analytical procedure derive gradient solely account trawling-induced (Partial RLQ analysis). Results Bottom was found be selective force composition majority studies. general, tube-dwelling were more typical low frequencies, whereas deep burrowing resistant at high frequencies. Although report significantly deleterious functions, pattern along never related life span, key response generally assumed express recoverability following disturbance. Furthermore, show trends multi-functionality community can negative or positive intensity gradient. Discussion We discuss relevance these results light developments framework dichotomy, guidelines data analysis context impact sea floor. Our findings emphasize fundamental concepts represent first step toward assessment oriented benthos-mediated biogeochemical processes.
