Methane-cycling is becoming more important in high-latitude ecosystems as global warming makes permafrost organic carbon increasingly available. We explored 387 samples from three high-latitudes regions (Siberia, Alaska and Patagonia) focusing on mineral/organic soils (wetlands, peatlands forest), lake/pond sediment and water. Physicochemical, climatic and geographic variables were integrated ...

The Cuscuta genus comprises obligate parasitic plants that have an unusually wide host range. Whether Cuscuta uses different infection strategies for different hosts or whether the infection strategy is mechanistically and enzymatically conserved remains unknown. To address this, we investigated molecular events during the interaction between field dodder (Cuscuta campestris) and two host species ...

Classification of zooplankton to species with broadband echosounder data could increase the taxonomic resolution of acoustic surveys and reduce the dependence on net and trawl samples for ‘ground truthing’. Supervised classification with broadband echosounder data is limited by the acquisition of validated data required to train machine learning algorithms (‘classifiers’). We tested the hypothesis ...

Under kontrollerte forhold i kar var det en positiv effekt av et vintersignal kombinert med brakkvann i RAS på vekst etter overføring til sjøvann. Men et vintersignal ga også økt kjønnsmodning i hannfisk når fisken gikk lenge i RAS på kontinuerlig lys etter at vintersignalet var avsluttet. Kjønnsmodning ble redusert når fisken ble satt ut på lav sjøtemperatur. Resultatene fra utsett i sjømerder viste ...

Little is currently known about how climate modulates the relationship between plant diversity and soil organic carbon and the mechanisms involved. Yet, this knowledge is of crucial importance in times of climate change and biodiversity loss. Here, we show that plant diversity is positively correlated with soil carbon content and soil carbon-to-nitrogen ratio across 84 grasslands on six continents ...

On 18 June, 1945 ,a 15½ year old boy, O.A.E. (born1929), was brought before the Stjørdal and Verdal court of inquiry together with his father. Both had spent two days in Vollan circuit jail and six weeks in Falstad internment camp on suspicion of criminal treason, as they during the German occupation had been members of the collaborationist party Nasjonal Samling (NS). According to the newspaper ...

Carnobacterium is a genus of Gram-positive bacteria, within family Carnobacteriaceae, and they are catalase- and oxidase-negative, non-sporing bacteria with properties such as CO² and L (+)- lactic acid production from glucose, but they are not able to grow on acetate agar. They are ubiquitous lactic acid bacteria and have been isolated from both cold and temperate environments, and ...

Permafrost soils store a substantial part of the global soil carbon and nitrogen. However, global warming causes abrupt erosion and gradual thaw, which make these stocks vulnerable to microbial decomposition into greenhouse gases. Here, we investigated the microbial response to abrupt in situ permafrost thaw. We sequenced the total RNA of a 1 m deep soil core consisting of up to 26 500-year-old permafrost ...

Creative thinking is crucial to address the sustainability challenge of academic conferences. Adopting a creativity lens, we explored the low-carbon initiatives and actions associated with an organizational studies conference in Italy. We relied on an action research approach that involved implementing one of the initiatives included in the study, interviews with key informants, and secondary data. ...

The ocean’s biological carbon pump (BCP) is a vital part of the global carbon cycle as it produces, transforms, and transfers organic carbon from the surface ocean to the deep. To model the oceans capacity to store carbon today and in the future, we need to understand these processes well. In the Eurasian Arctic, the marine ecosystems who control most of the BCP face a rapid decline in sea ice cover, ...
