1. 6. Mechanisms of below-ground carbon cycling in subarctic ecosystems

   Författare :Maria Olsrud; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; pedology; geomorphology; Physical geography; subarctic tundra; phosphorous mobilization; organic acids; open top chamber experiment; 15N natural abundance; Ericoid mycorrhizas; global change; 14C pulse-labelling; Carbon allocation;

   Sammanfattning : Some components of the below-ground carbon (C) cycle in terrestrial ecosystems are still poorly understood. A better understanding will be necessary to predict adequately the impacts of global change factors on C cycling and storage, especially in high-latitude ecosystems, where much of the C is stored below-ground.

3. 7. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field

   Författare :Zsofia Réka Stangl; Vaughan Hurry; Lisa Ainsworth; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

   Sammanfattning : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. LÄS MER

5. 9. Essays on Energy and Climate Policy – Green Certificates, Emissions Trading and Electricity Prices

   Författare :Anna Widerberg; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attitudes; Carbon Dioxide; Carbon Intensity; Climate Change; Electricity; Electricity Prices; Emissions Trading; Emission Allowances; Environment; Fairness; GARCH models; Lyapunov Exponents; Market Structure; Personal Carbon Allowances; Public Opinion; Reconstructed Dynamics; Stability; Tradable Energy Quotas; Tradable Green Certificates; Volatility;

   Sammanfattning : Paper I: An Electricity Trading System with Tradable Green Certificates and CO₂-emission Allowances Combinations of various policy instruments to deal with the threat of climate change are used throughout the world. The aim of this article is to investigate an electricity market with two different policy instruments, Tradable Green Certificates (TGCs) and CO₂ emission allowances (an Emission Trading System, ETS).

7. 10. Carbon in Boreal Streams : Isotopic Tracing of Terrestrial Sources

   Författare :Audrey Campeau; Marcus Wallin; Kevin Prof; Emily Stanley; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The boreal biome comprises vast areas of coniferous forests, dotted with millions of peatlands. Plants harbouring these ecosystems fix CO2 from the atmosphere, which is later incorporated into the vegetation biomass and subsequently buried in soils. LÄS MER
