Abstract Kelps act as ecosystem engineers on many polar rocky shore coastlines. The underwater light climate and temperature are the main drivers for their vertical latitudinal distribution. With temperatures rising globally, an Arctic expansion of temperate kelp species accelerating glacial melt is predicted. It was our aim to investigate effects retreating glaciers potential habitat kelps in fjords. We analyzed areas being influenced by different stages retreat (sea‐terminating glacier,...
Abstract Background The sugar kelp Saccharina latissima is a Laminariales species widely distributed in the Northern Hemisphere. Its physiology and ecology have been studied since 1960s, given its ecological relevance on western temperate coasts. However, research interest has rising recently, driven mainly by reports of negative impacts anthropogenically induced environmental change increased commercial cultivating species, with several industrial applications for resulting biomass. Scope...
Abstract The sugar kelp Saccharina latissima has received intense scientific attention over the last decades. In recent years, interest in cultivation of species strongly increased North Atlantic Ocean and Eastern Pacific Ocean, driven by great potential S. to be utilised for various industrial applications, including food, feed, biomaterials. Accordingly, current research focused on improving farming methods technology, environmental impacts, site selection. addition, many studies have...
Abstract Kelps (Phaeophyceae, Laminariales) are ecosystem engineers along Arctic rocky shores. With ongoing climate change, the frequency and intensity of marine heatwaves increasing. Further, extensive meltwater plumes darken fjords. Assessing effect a sudden temperature increase at cold-distribution limit cold-temperate kelp species, we compared responses two species ( Agarum clathratum , Saccharina latissima ) to realistic summer heatwave scenarios (4–10°C) under low- high-light...
A wide range of microorganisms inhabit biocrusts arctic and sub-arctic regions. These taxa live thrive under extreme conditions and, moreover, play important roles in biogeochemical cycling. Nevertheless, their diversity abundance remain ambiguous. Here, we studied microbial community composition from Svalbard Iceland using amplicon sequencing epifluorescence microscopy. Sequencing 16S rRNA gene revealed the dominance Chloroflexi Longyearbyen, Acidobacteria Ny-Ålesund South Svalbard. Within...
Summary The geographical distribution of organisms, such as the foundation kelp species Saccharina latissima , is mainly driven by temperature. Globally increasing sea surface temperature and further intensification marine heatwaves have already resulted in local extinction populations worldwide. In present study, we investigated temporal variation thermal susceptibility S. assessing stress responses field sporophytes sampled from Helgoland (German Bight) June 2018, August 2018 2019 heatwave...
Abstract Due to global rises in temperature, recent studies predict marine species shifting toward higher latitudes. We investigated the impact of interacting abiotic drivers on distribution potential temperate kelp Laminaria hyperborea . The ecosystem engineering is widespread along European coasts but has not yet been observed High Arctic, although it can survive several months low temperatures and darkness. To investigate its ability extend northward future, we conducted a long‐term...

Kelps (Laminariales, Phaeophyceae) are foundation species along Arctic rocky shores, providing the basis for complex ecosystems and supporting a high secondary production. Due to ongoing climate change glacial terrestrial run-off currently accelerating, drastically changing physical chemical water column parameters, e.g., transparency photosynthetically active radiation or dissolved concentrations of (harmful) elements. We investigated performance functioning kelp holobionts in response...
The Arctic is seasonally exposed to long periods of low temperatures and complete darkness. Consequently, perennial primary producers have apply strategies maximize energy efficiency. Global warming occurring in the faster than rest globe. highest amplitude temperature rise occurs during Polar Night. To determine stress resistance ecosystem-engineering kelp Laminaria digitata against winter warming, non-meristematic discs adult sporophytes from Porsangerfjorden (Finnmark, Norway) were kept...
