Shallow benthic Antarctic food webs recover complexity after disturbance
Read more of: Shallow benthic Antarctic food webs recover complexity after disturbanceNatural disturbance events are expected to increase with climate change. This is particularly evident in polar regions where reduced winter sea-ice has increased movement of icebergs, and thus seafloor scouring. […]

Lake sediment records of deglaciation and post-glacial paleoenvironmental conditions, northeast Pennsylvania, USA
Read more of: Lake sediment records of deglaciation and post-glacial paleoenvironmental conditions, northeast Pennsylvania, USASediment cores from two glacial lake basins in northeast Pennsylvania, USA, record the timing of Laurentide Ice Sheet (LIS) retreat along with post-glacial climate and environmental conditions. Basal radiocarbon ages […]

Projected warming disrupts temperate serpulid communities, key engineers of benthic ecosystems: evidence from in situ thermal experiments
Read more of: Projected warming disrupts temperate serpulid communities, key engineers of benthic ecosystems: evidence from in situ thermal experimentsGlobal ocean warming is reshaping marine communities, with consequences for species- and community-level functioning. Serpulid polychaetes are a key component of benthic ecosystems that may be particularly vulnerable to rising […]

Ikaite precipitation indicates near surface occurrence of methane in an Icelandic fjord
Read more of: Ikaite precipitation indicates near surface occurrence of methane in an Icelandic fjordClimate change driven release of methane (CH4) from polar and sub-polar sediments could accelerate global warming, and tracking CH4 in cold sediments over geological time helps predict future releases. Isotopic […]

Antarctic, Southern Ocean, and Global Ocean Temperatures during Dansgaard–Oeschger Events [preprint]
Read more of: Antarctic, Southern Ocean, and Global Ocean Temperatures during Dansgaard–Oeschger Events [preprint]Global Mean Ocean Temperature (GMOT) changes are thought to be both an important consequence and a possible cause of Dansgaard-Oeschger (DO) events, a series of abrupt climate changes during the […]

Moss-associated metabolites decrease antibiotic-resistant Enterobacterales in urban environment
Read more of: Moss-associated metabolites decrease antibiotic-resistant Enterobacterales in urban environmentHuman activity intensifies the spread of antibiotic resistance genes (ARGs), threatening environmental and public health. Plant metabolite-microbe interactions play a crucial role in mitigating ARGs by shaping the soil environment. […]

Soil arthropod communities are better predictors of soil quality than nematodes in agricultural soils
Read more of: Soil arthropod communities are better predictors of soil quality than nematodes in agricultural soilsSoil ecosystems are shaped by complex interactions between their biological communities, environmental conditions and physicochemical properties. However, higher-trophic soil fauna is often neglected in soil risk assessments. This study utilized […]

Functional Genetic Potential Of Benthic Microbial Mat Communities in Arctic, Antarctic and Sub-Antarctic Lakes
Read more of: Functional Genetic Potential Of Benthic Microbial Mat Communities in Arctic, Antarctic and Sub-Antarctic LakesBenthic microbial mat communities are key drivers of ecosystem functioning in polar lakes and ponds, forming the base of aquatic food webs and contributing substantially to nutrient cycling. Although Arctic, […]

Diatom–environment relationships and limnological variability: an updated quantitative tool for palaeoclimatology on sub-Antarctic Macquarie Island
Read more of: Diatom–environment relationships and limnological variability: an updated quantitative tool for palaeoclimatology on sub-Antarctic Macquarie IslandSub-Antarctic Macquarie Island is ideally located for reconstructing past variations in Southern Hemisphere westerly wind strength. Diatoms are a valuable palaeolimnological tool on sub-Antarctic islands, providing a means to reconstruct […]
