1. 11. THE INFLUENCE OF TUNDRA VEGETATION ON SOIL TEMPERATURES

   Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Författare :Edith Aspelin; [2022-09-28]
   Nyckelord :;

   Sammanfattning : The arctic has experienced more rapid global warming and is more sensitive to temperature changes compared with the rest of the world. We can already see how vegetation distributed across the arctic tundra has changed in composition, height, and abundance. LÄS MER

3. 12. POSSIBLE TIMING OF THE TRANSITION FROM PRE-INDUSTRIAL TO INDUSTRIAL CLIMATE IN THE CENTRAL TO NORTHERN OF SWEDEN, BASED ON PROXY DATA FROM TREE-RINGS

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Mika Falkensjö Oppenheim; [2022-09-28]
   Nyckelord :Tree-ring; maximum latewood density MXD ; Scandinavia; pre-industrial; industrial climate;

   Sammanfattning : Earth’s climate has varied through time, with orbital forcing as the most dominant force on the climate system the last million years, causing glacial-interglacial cycles. The last glacial period ended about 11.6 thousand years (kyr), ago and the last interglacial maximum around 6.5 kyr ago. LÄS MER

4. 13. FLOWERING TIME DEPENDENCE ON MICROCLIMATE ACROSS AN ELEVATIONAL GRADIENT IN ARCTIC PLANT COMMUNITIES

   Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Författare :Maria Pavolotskaia; [2022-07-06]
   Nyckelord :The Arctic; flowering time; flowering phenology; elevation; elevational gradient; temperature; snowmelt; snow cover; microclimate.;

   Sammanfattning : The Arctic is the fastest-warming region on Earth. Arctic plant communities are highly sensitive to temperature change; temperature-dependent advancement of flowering dates has already been observed in the Arctic. Flowering time is critical for reproductive success. LÄS MER

5. 14. ARCTIC PLANT COMMUNITIES RISE WITH TEMPERATURE Plant functional traits as a tool to predict global climate change

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Helena Sundell; [2022-07-06]
   Nyckelord :Arctic warming; plant functional traits; Community Weighted Mean; vegetational changes; global climate change;

   Sammanfattning : Global warming occurs at a rate at least three-fold in the arctic regions compared to the rest of the world. Here, plant community functional traits were assessed in response to experimental warming in three arctic areas of Fennoscandia (Latnajajure, Abisko and Kilpisjärvi). LÄS MER

7. 15. INDIVIDUAL TRAIT MATCHING OF BUMBLEBEES (BOMBUS) AND FLOWERS ALONG AN ENVIRONMENTAL GRADIENT

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Johan Per Michael Svedin; [2022]
   Nyckelord :Arctic climate change; Bombus; Flower morphology; Plant-pollinator trait-matching;

   Sammanfattning : Insect pollinators serve a critical role in maintaining plant biodiversity and are especially susceptible to changes within their environment. To study the possible effects of seasonal variation in temperature, as well as climatic temperature increase on the plant-pollinator community, the relationship between bumblebee and flowering plant traits along an elevational gradient, representing warming-induced changes in plant community, were examined.
