1. 1. Patterns in diversity : Geochemical analyses and settlement changes during the Iron Age - Early Medieval time in the Lake Mälaren region, Sweden

   Författare :Björn Hjulström; Sven Isaksson; Michael Parker Pearson; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Arkeologi; Archaeological Science; laborativ arkeologi;

   Sammanfattning : The principal aims of this thesis were two-fold, encompassing both a geochemical approach and a focus on the settlement structure of the Lake Mälaren region of Sweden during the first millennium A.D. LÄS MER

3. 2. Timing Modes for the MAX IV Storage Rings

   Författare :Teresia Olsson; Lunds universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synchrotron light storage rings; timing experiments; ultralow emittance; harmonic cavities; fill patterns; PPRE; PSB; Fysicumarkivet A:2018:Olsson;

   Sammanfattning : The MAX IV facility includes two storage rings, operated at 1.5 and 3 GeV energy, for the purpose of producing high-brilliance synchrotron radiation for users. The 1.5 GeV ring replaces the previous MAX II and MAX III storage rings as a source of UV and soft X-rays, whereas the 3 GeV ring is optimized for hard X-rays. LÄS MER

4. 3. Distribution patterns of fleshy-fruited woody plants at local and regional scales

   Författare :Matilda Arnell; Ove Eriksson; Johan Ehrlén; Sara A.O. Cousins; Angela Moles; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fleshy fruits; woody plants; dispersal; distribution patterns; range filling; dispersal limitation; historical land use; spatial associations; point-pattern analysis; recruitment; reproduction; pollination; fruit set; fruit-removal; Daphne mezereum; Plant Ecology; växtekologi;

   Sammanfattning : Fleshy-fruited woody plants share a long history with humans, providing us with food and wood material. Because of this relation, we have actively moved some of these plants across landscapes and continents. LÄS MER

5. 4. Global patterns of international fisheries conflict

   Författare :Jessica Spijkers; Henrik Österblom; Matthew Osborne; Tiffany Morrison; Graeme S. Cumming; Geoff Dabelko; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fisheries; conflict; environmental security; social-ecological systems; complex adaptive systems thinking; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : Are international conflicts over fishery resources a growing security concern? High-profile incidences of conflict, diminishing fishery resources and climate impacts on marine systems have made the international community increasingly wary of fisheries conflict. However, we lack knowledge on conflict incidences over time, as well as the contexts in which the conflicts occur, to assess if fisheries conflict is a growing security threat. LÄS MER

7. 5. Environmental sequencing to infer patterns of eukaryotic evolution : Combining long-read and short-read metabarcoding

   Författare :Mahwash Jamy; Fabien Burki; Micah Dunthorn; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protists; eukaryotes; environmental sequencing; ribosomal DNA; PacBio; long-read metabarcoding; phylogenetics; salt barrier; habitat evolution; eukaryotes evolution; evolutionary rate; Apicomplexa; pathogen; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

   Sammanfattning : Our view of eukaryotes is biased towards plants, animals, and fungi. But the vast majority of eukaryotic diversity is microbial in nature. These microbial eukaryotes are key players in all ecosystems on earth and are collectively known as protists. LÄS MER
