Abstract Marine benthic ecosystems are difficult to monitor and assess, which is in contrast modern ecosystem-based management requiring detailed information at all important ecological anthropogenic impact levels. Ecosystem needs ensure a sustainable exploitation of marine resources as well the protection sensitive habitats, taking account potential multiple-use conflicts impacts over large spatial scales. The urgent need for large-scale data on species communities resulted an increasing...
Abstract This study provides an inventory of the recent benthic macrofaunal communities in entire Baltic Sea. The analyses soft-bottom invertebrate community data based on over 7000 locations Sea suggested existence 10 major species abundances and 17 biomasses, respectively. low-saline northern Baltic, characterized by silty sediments, is dominated Monoporeia affinis, Marenzelleria spp., Macoma balthica. Hydrobiidae, Pygospio elegans, Cerastoderma glaucum dominate sandy habitats off Estonian...
Abstract Bottom trawl fishing is a controversial activity. It yields about quarter of the world's wild seafood, but also has impacts on marine environment. Recent advances have quantified and improved understanding large‐scale trawling seabed. However, such information needs to be coupled with distributions benthic invertebrates (benthos) assess whether these populations are being sustained under current regimes. This study collated data from 13 diverse regions globe spanning four...
Many studies show that habitat complexity or diversity plays a major role in biodiversity throughout different spatial scales: as structural heterogeneity increases, so does the number of available (micro-) habitats for potential species inventory. The capability housing (even rare species) increases rapidly with increasing heterogeneity. However, is not easy to measure marine sublittoral sediments. In our study, we came up proposal estimate benthic using standard underwater video...
Quantifying the impact of lower trophic level species abundance on higher predators (and vice versa) is critical for understanding marine ecosystem dynamics and implementing ecosystem-based management. Trophic models generally predict a tight coupling between prey fish predators, such that results in predators. This assumes predator feeding rates to some degree are limited by availability. Despite being key component predator-prey interactions multi-species fisheries management, relatively...
Biological long-term data series in marine habitats are often used to identify anthropogenic impacts on the environment or climate induced regime shifts. However, particularly transitional waters, environmental properties like water mass dynamics, salinity variability and occurrence of oxygen minima not necessarily caused by either human activities change can attenuate mask apparent signals. At first glance it very seems impossible interpret strong fluctuations e.g. abundances species...
During several cruises in the southern Baltic Sea conducted different seasons from 2014 to 2016, sediment cores were collected for investigation of pore-water biogeochemistry and associated nutrient fluxes across sediment-water interface. Six stations positioned along a salinity gradient (ranging 22 8) covered various sedimentary habitats ranging mud sand. Integrated nutrients supernatant water oxygen consumption additionally derived incubations intact cores. Subsequently, incubation was...
During three cruises to the Bay of Gdansk, Baltic Sea, fauna, porewater and bottom water were sampled at stations parallel shore along a transect offshore. Diffusive fluxes calculated related total net (TNF) nutrients. The TNF comprise all nutrients that reach from sediment including diffusive nutrient efflux, discharge macrozoobenthos microbial activity. They determined during in situ incubations using benthic chamber lander, which is rarely done coastal research. lander restricts physical...
Abstract Species in the brackish and estuarine ecosystems will experience multiple changes hydrographic variables due to ongoing climate change nutrient loads. Here, we investigate how a glacial relict species (Saduria entomon), having relatively cold, low salinity biogeographic origin, could be affected by combined scenarios of eutrophication. It is an important prey for higher trophic-level such as cod, predator other benthic animals. We constructed habitat distribution models based...
Abstract. The availability of standardised biomass data is essential for studying population dynamics, energy flows, fisheries and food web interactions. To make the estimates consistent, weight-to-weight conversion factors are often used, example to translate more widely available measurements wet weights into required dry ash-free weight metrics. However, many species groups applicable freely have until now remained very rough approximations with high degree taxonomic generalisation. close...
Abstract An organism’s body condition describes its mass given length and is often positively associated with fitness. The of Atlantic cod (Gadus morhua) in the Baltic Sea has declined dramatically since early 1990s, possibly due to increased competition for food hypoxia. However, effects biotic abiotic variables on have not been evaluated at local scales, which important spatial heterogeneity. We evaluate changes distribution, experienced environmental conditions, individual-level relation...
Trawl-fishing is broadly considered to be one of the most destructive anthropogenic activities toward benthic ecosystems. In this study, we examine effects bottom-contact fishing by otter trawls on geochemistry and macrofauna in sandy silt sediment an area Baltic Sea where clear spatial patterns trawling activity were previously identified acoustic mapping. We calibrated early diagenetic model biogeochemical data from various coring locations. Fitting measured mercury profiles allowed for...
