Unexpected Levels of Biological Activity during the Polar Night Offer New Perspectives on a Warming Arctic
The current understanding of Arctic ecosystems is deeply rooted in the classical view of a bottom-up controlled system with strong physical forcing and seasonality in primary-production regimes.Expand

An assessment of seabird influence on Arctic coastal benthic communities
Abstract It is well recognized that seabirds, particularly those nesting in coastal colonies, can provide significant nutrient enrichment to Arctic terrestrial ecosystems. However, little is knownExpand

Following the flow of ornithogenic nutrients through the Arctic marine coastal food webs
Abstract Arctic colonial seabirds are recognized as effective fertilizers of terrestrial ecosystems by delivering marine-origin nutrients to the vicinities of their nesting sites. A proportion ofExpand

Hermit crabs (Pagurus spp.) at their northernmost range: distribution, abundance and shell use in the European Arctic
Hermit crabs are important components of Arctic benthic systems, yet baseline data on their densities and distribution patterns in this rapidly changing region are still scarce. Here we compileExpand

Seasonality in vegetation biometrics and its effects on sediment characteristics and meiofauna in Baltic seagrass meadows
Abstract Seagrass meadows can act as ecosystem engineers, i.e., organisms that modify the availability of resources to other organisms. However, their possible positive impacts depend on theExpand

Growth Rate of Selected Sheet-Encrusting Bryozoan Colonies Along a Latitudinal Transect: Preliminary Results
Climate change driven alterations of sea-water temperature, salinity, acidity and primary production in many coastal regions will probably affect the ecophysiological performance of sedentaryExpand

Evidence of Season-Dependency in Vegetation Effects on Macrofauna in Temperate Seagrass Meadows (Baltic Sea)
Seagrasses and associated macrophytes are important components of coastal systems as ecosystem engineers, habitat formers, and providers of food and shelter for other organisms. The positive impactsExpand

Seasonal and multi-annual patterns of colonisation and growth of sessile benthic fauna on artificial substrates in the brackish low-diversity system of the Baltic Sea
Although benthic succession is well understood, the growth of assemblages does not follow the same progression across environmental variables and differs among coastal ecosystems. This studyExpand

Mobile hard substrata – An additional biodiversity source in a high latitude shallow subtidal system
Abstract This study demonstrates the importance of a hard mobile substratum (hermit crab shells) for Arctic biodiversity. Based on previous observations from other geographic regions we hypothesizedExpand

Species pool structure explains patterns of Antarctic rock-encrusting organism recruitment
Understanding the population dynamics of benthic communities is impossible without understanding the processes related to their initial development, including recruitment. In polar areas, encrustingExpand
