Natural variability or anthropogenically-induced variation? Insights from 15 years of multidisciplinary observations at the arctic marine LTER site HAUSGARTEN
Abstract Time-series studies of arctic marine ecosystems are rare. This is not surprising since polar regions are largely only accessible by means of expensive modern infrastructure andExpand
Major impacts of climate change on deep-sea benthic ecosystems
The deep sea encompasses the largest ecosystems on Earth. Although poorly known, deep seafloor ecosystems provide services that are vitally important to the entire ocean and biosphere. RisingExpand
Ocean acidification increases the vulnerability of native oysters to predation by invasive snails
Testing whether ocean acidification, driven by elevated seawater pCO2, increases the susceptibility of native Olympia oysters to predation by invasive snails finds that smaller individuals were consumed at disproportionately greater rates. Expand
Rocky islands in a sea of mud: biotic and abiotic factors structuring deep-sea dropstone communities
The hypothesis that dropstones would have the same species distribution patterns as terrestrial islands was tested, using 5 patterns commonly found in the classical island literature to offer alternative mechanisms for dropstones. Expand
Recruitment of benthic invertebrates in high Arctic fjords: Relation to temperature, depth, and season
Recruitment in Svalbard is highly variable, both spatially and temporally, and the results show the influence of local factors such as adult species composition, which can be described as pioneer (early-succession) species. Expand
Diversity, endemism and conservation of the freshwater crabs of China (Brachyura: Potamidae and Gecarcinucidae).
There is an urgent need for increased species exploration and for the development of a conservation strategy for China's threatened (and potentially threatened) endemic freshwater crab species. Expand
Interannual variation in the epibenthic megafauna at the shallowest station of the HAUSGARTEN observatory (79° N, 6° E)
Epibenthic megafauna play an important role in the deep-sea environment and contribute significantly to benthic biomass, but their population dynamics are still understudied. We used a towed deep-seaExpand
Key role of bacteria in the short-term cycling of carbon at the abyssal seafloor in a low POC flux region of the eastern Pacific Ocean
The cycling of carbon (C) by benthic organisms is a key ecosystem function in the deep sea. Pulse-chase experiments are designed to quantify this process, yet few studies have been carried out usingExpand
High Biodiversity on a Deep-Water Reef in the Eastern Fram Strait
The east side of the reef summit, where the highest richness and density of fauna are found, faces into the predominant bottom current, which likely increases in speed to the summit and serves as a source of particulate food for the numerous suspension feeders present there. Expand
Environmental factors structuring Arctic megabenthos—a case study from a shelf and two fjords
From photographic samples, we describe the benthic megafaunal communities in two north Svalbard fjords and on the adjacent continental shelf. We analyze the fauna in relation to abiotic factors ofExpand
