Tiny titans: Impact of Meiofauna diversity and activity on coastal sediment biogeochemistry
(2024-11-11)Chemical reactions in marine sediments and the resulting fluxes across the sediment-water interface influence ecosystem functioning, global carbon cycling, and ultimately global habitability. Although previous research has ... -
Methane offsets to carbon sequestration in coastal ecosystems
(2024-11-08)Mangroves, saltmarshes, and seagrasses are known as blue carbon ecosystems because of their high rates of productivity and efficiency in sequestering carbon. Carbon can be stored in sediments, biomass, exported laterally ... -
Drivers affecting seagrass meadows: An approach for conservation and restoration in Mozambique
(2024-09-30)Seagrasses and other shallow-water vegetation are important coastal habitat because they provide many ecosystem services, including food, shelter and nursery areas of shellfish and finfish as well as marine endangered ... -
Carbon outwelling and greenhouse gas exchange across mangrove seascapes
(2024-08-09)Mangroves, renowned for their high primary productivity and carbon burial rates, play a crucial role in the ocean carbon cycle. However, uncertainties persist regarding the fate of mangrove-derived carbon across seascapes. ... -
The role of chromosomal inversions in rough periwinkle snails (Littorina saxatilis)
(2024-04-15)Chromosomal inversions are genomic rearrangements that may have a major role in local adaptation, facilitating ecotype formation and speciation. Recombination can hinder these processes as it breaks apart beneficial ... -
On the generation of Maud Rise polynyas in the Weddell Sea
(2024-04-12)The Weddell Sea is a region prone to the formation of open-ocean polynyas. Open-ocean polynyas are offshore openings of sea ice in the winter season, often accompanied by deep convection. Deep convection allows for the ... -
From alpha to beta ocean: Exploring the role of surface buoyancy fluxes and seawater thermal expansion in setting the upper ocean stratification
(2023-12-05)The ocean plays a central role in the climate system by absorbing excess anthropogenic heat and carbon dioxide. Moreover, the ocean circulation distributes heat from the tropics towards the poles. Due to the large ocean ... -
Connections between biodiversity and ecosystem functioning in large-scale natural ecosystems
(2023-11-21)Billions of years of evolution have given us a planet that supports a remarkable diversity of life. Estimates for the number of Eukaryotic species frequently number in the millions and the Prokaryotes are much more diverse ... -
Seaweeds as a future protein source: innovative cultivation methods for protein production
(2023-10-20)As the global population is projected to reach approximately 10 billion people by 2050, it is estimated that we will need to produce up to 60% more food compared to 2010. Although the current food production system contributes ... -
Survivors of the Sea: Investigating the genomics and survival strategies of the diatom Skeletonema marinoi
(2023-09-14)Diatoms are an ecologically important group of phytoplankton, responsible for around 20% of global primary production. One of the features contributing to their success is their ability to form resting stages, a response ... -
Single cell carbon and nitrogen dynamics in chain forming diatoms, including their resting stage
(2023-08-10)The oceans are a fundamental part of all life on earth, accounting for more than half of Earth’s oxygen production. The ocean is also key to long term carbon dioxide sequestration. Diatoms are a group of phytoplankton ... -
Nutrient Transfer in Aquaponic Systems – Optimizing microbial processes for greater circularity and economic viability
(2023-04-18)The trend towards sustainable process design in modern industries combines the goal of improving process efficiency with a conscientious shift towards resource conservation. Aquaponics, a system that involves co-cultivating ... -
Evolutionary and Ecological Effects of Metal Pollution on Coastal Diatoms
(2022-10-21)Oceans are changing rapidly in response to human activities, such as toxic pollution, eutrophication, and climate change. Diatoms are major primary producers in the oceans with short generation times, flexible reproductive ... -
Modelling the Evolution of Species’ Ranges
(2022-09-16)The fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental ... -
Microbial degradation of wooden foundation piles in urban context – causes and concerns
(2022-05-18)Modern infrastructural projects can endanger historical piled foundations supporting cultural heritage buildings, as groundwork can affect the subsurface environment by lowering the local groundwater level and increasing ... -
Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export
(2022-05-12)The sea ice impacted Southern Ocean, south of the Antarctic Circumpolar Current, is one of the most important regions on earth for the cycling of carbon and distribution of heat and freshwater around the globe. Here, ... -
Ocean mixing and polynyas at Maud Rise, Weddell Sea
(2022-04-22)The Weddell Sea Polynya is an intermittent, ice free area in the marginal ice zone with an extent of up to 350 000 km². It was first observed by satellites in the winter seasons of 1974-1976. In 2016 and 2017, an open-ocean ... -
Crossing barriers: Genetic consequences of translocating wild cleaner fish for aquaculture
(2022-04-21)Several species of fish show a symbiotic cleaning behaviour, where they assist other species by feeding and removing dead skin or ectoparasites. Some of these cleaner fish species are used as a low-cost parasite control ... -
Nutrient dynamics in coastal and shelf oceans - sediments as a regulator of eutrophication feedbacks
(2022-01-10)Coastal and shelf systems are under increasing pressure from human activities. Many coastal systems currently suffer from excessive algae growth following increased nutrient input from land, a process called eutrophication. ...
