Recruitment of benthic invertebrates in high Arctic fjords: Relation to temperature, depth, and season
Sign Up to like & getrecommendations! Published in 2017 at "Limnology and Oceanography"
DOI: 10.1002/lno.10602
Abstract: In the high Arctic, recruitment of hard-bottom benthic organisms has been studied at single locations, but little is known about how it varies spatially or temporally, or how it is influenced by abiotic factors. In… read more here.

Methane cold seeps as biological oases in the high‐Arctic deep sea
Sign Up to like & getrecommendations! Published in 2018 at "Limnology and Oceanography"
DOI: 10.1002/lno.10732
Abstract: Cold seeps can support unique faunal communities via chemosynthetic interactions fueled by seabed emissions of hydrocarbons. Additionally, cold seeps can enhance habitat complexity at the deep seafloor through the accretion of methane derived authigenic carbonates… read more here.

DOI: 10.1002/qj.3877
Abstract: Wintertime warm extremes in the high Arctic, primarily associated with intrusions of moist airmasses from the midlatitudes, have occurred with an ostensibly high frequency in recent years. Here, we compute the temperature anomaly return values… read more here.

Microbial Organic Matter Utilization in High-Arctic Streams: Key Enzymatic Controls
Sign Up to like & getrecommendations! Published in 2019 at "Microbial Ecology"
DOI: 10.1007/s00248-019-01330-w
Abstract: In the Arctic, climate changes contribute to enhanced mobilization of organic matter in streams. Microbial extracellular enzymes are important mediators of stream organic matter processing, but limited information is available on enzyme processes in this… read more here.

DOI: 10.1007/s10021-018-0323-4
Abstract: Herbivores are key drivers of vegetation dynamics in most ecosystems. However, the effect of high arctic herbivores on vegetation dynamics throughout a growing season is not well understood. In this study, we examine the impacts… read more here.

DOI: 10.1007/s10021-020-00506-7
Abstract: Increasing air temperatures are driving widespread changes to Arctic vegetation. In the high Arctic, these changes are patchy and the causes of heterogeneity are not well understood. In this study, we explore the determinants of… read more here.

Nitrogen fixation in the High Arctic: a source of ‘new’ nitrogen?
Sign Up to like & getrecommendations! Published in 2017 at "Biogeochemistry"
DOI: 10.1007/s10533-017-0393-y
Abstract: Biological nitrogen (N2) fixation performed by diazotrophs (N2 fixing bacteria) is thought to be one of the main sources of plant available N in pristine ecosystems like arctic tundra. However, direct evidence of a transfer… read more here.
