Carbon and microbes in a degrading palsa mire are distinct from a peatland and a wider connected sub-Arctic fluvial system Open
Climate change is altering the biogeochemical cycling of carbon and nutrients in the northern peatland and permafrost regions, which provide one of the largest terrestrial carbon storages. Lateral transfer of carbon needs to be more widely…

Biodegradation of different bioplastics by specialised microbial communities in a coastal brackish environment Open
Bioplastics are frequently promoted as a more sustainable alternative to conventional plastics. Microorganisms are metabolically versatile and central to marine ecosystems, yet the potential of marine microbial communities to degrade diffe…

Observation‐Based Estimate of Net Community Production in Antarctic Sea Ice Open
Antarctic sea ice is one of the largest biomes on Earth providing a critical habitat for ice algae. Measurements of primary production in Antarctic sea ice remain scarce and an observation‐based estimate of primary production has not been …

Changes in riverine dissolved organic matter caused by gypsum‐induced flocculation Open
Gypsum (CaSO 4 ·2H 2 O) is increasingly used to bind P to soil on agricultural fields, which mitigates eutrophication caused by runoff of excess PO 4 3− fertilizers into adjacent aquatic environments. Gypsum also binds dissolved organic ma…

Plastic pollution and human pathogens: Towards a conceptual shift in risk management at bathing water and beach environments Open
Emerging evidence indicates that micro- and macro-plastics present in water can support a diverse microbial community, including potential human pathogens (e.g., bacteria, viruses). This interaction raises important concerns surrounding th…

Organising for Social Change: A Study in the Theory and Practice of Community Work Open
Originally published in 1976, the aim of this book was to understand the contribution of community work to meeting some of the problems to be found in many of Britain’s inner city neighbourhoods. It describes the community work process and…

Societal implications of a changing Arctic Ocean Open
The Arctic Ocean is undergoing rapid change: sea ice is being lost, waters are warming, coastlines are eroding, species are moving into new areas, and more. This paper explores the many ways that a changing Arctic Ocean affects societies i…

Sea-Ice Bacteria <i>Halomonas</i> sp. Strain 363 and <i>Paracoccus</i> sp. Strain 392 Produce Multiple Types of Poly-3-Hydroxyalkaonoic Acid (PHA) Storage Polymers at Low Temperature Open
Plastic pollution is one of the most topical threats to the health of the oceans and seas. One recognized way to alleviate the problem is to use degradable bioplastic materials in high-risk applications.

Shift from Carbon Flow through the Microbial Loop to the Viral Shunt in Coastal Antarctic Waters during Austral Summer Open
The relative flow of carbon through the viral shunt and the microbial loop is a pivotal factor controlling the contribution of secondary production to the food web and to rates of nutrient remineralization and respiration. The current stud…

Hydrocarbon-Degrading Bacteria Alcanivorax and Marinobacter Associated With Microalgae Pavlova lutheri and Nannochloropsis oculata Open
Marine hydrocarbon-degrading bacteria play an important role in natural petroleum biodegradation processes and were initially associated with man-made oil spills or natural seeps. There is no full clarity though on what, in the absence of …

Platelet ice, the Southern Ocean's hidden ice: a review Open
Basal melt of ice shelves is not only an important part of Antarctica's ice sheet mass budget, but it is also the origin of platelet ice, one of the most distinctive types of sea ice. In many coastal Antarctic regions, ice crystals form an…

Life Inside and Under Frozen Seawater Open
Seawater freezes below -2.0°C and therefore ice covers vast areas of the polar oceans for part of every year. First, ice crystals float to surface; then ice floes form to create a frozen landscape on the ocean surface. This pack ice moves …

Maternal and cohort effects modulate offspring responses to multiple stressors Open
Current concerns about climate change have led to intensive research attempting to understand how climate-driven stressors affect the performance of organisms, in particular the offspring of many invertebrates and fishes. Although stressor…
