2. 1. Embracing Science : Sino-Swedish Collaborations in the Field Sciences, 1902–1935

   Author : Jan Romgard; Marja Kaikkonen; Stephen Morgan; Hans Ulrich Vogel; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Republican China; history of science; Geological Survey of China; Academia Sinica; Ding Wenjiang; Weng Wenhao; geology; palaeontology; archaeology; palaeoanthropology; geography; modernization; nationalism; scientific communities; international collaboration; Johan Gunnar Andersson; Sven Hedin; Erik Nyström; Swedish Museum of Natural History; Sino-Swedish Expedition; Central Asia; Asian Languages and Cultures; Asiens språk och kulturer;

   Abstract : In 1902, a Swedish professor at Shanxi University started to study the region’s geology and in 1913, he suggested to the Chinese Republican Government an expansion of these surveys nationwide. As a result, the Head of the Geological Survey of Sweden, J. G. Andersson, was employed as a geological adviser to the Chinese Government. READ MORE

4. 2. Population History and Non-invasive Monitoring : Use of low copy number DNA in Conservation Genetics

   Author : Øystein Flagstad; Ettore Randi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; genetic tagging; immigration; loss of genetic variability; non-invasive molecular techniques; population decline; Swayne’s hartebeest; wolf; wolverine; Biologi; Biology; Biologi; ekologisk botanik; Ecological Botany;

   Abstract : Conservation genetics research is increasingly becoming an integrated part of the management of small and endangered populations. In this thesis I developed tools for genetic analysis of low copy number sources of DNA, such as old teeth from museum specimens as well as field-collected faeces and urine. READ MORE

5. 3. In Murky waters : Swedish demosponges and their genealogies

   Author : Raquel Pereira; Mikael Thollesson; Hanna Johannesson; Dirk Erpenbeck; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Porifera; Swedish sponge fauna; Spongilla lacutsris; population structure; Suberites; Suberitida; Syringella; Systematics; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

   Abstract : Swedish Sponge fauna last updated happened over 80’s years ago. This fact explains, partially, the country’s low sponge. READ MORE

6. 4. Silurian vertebrates of Gotland (Sweden) and the Baltic Basin

   Author : Oskar Bremer; Henning Blom; Per E. Ahlberg; Tiiu Märss; Héctor Botella; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; early vertebrates; vertebrate microremains; scale taxonomy; early vertebrate distribution; environmental preferences; Silurian; Baltic Basin; Gotland; Sweden; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

   Abstract : During the Silurian, the Swedish island Gotland was positioned close to the equator and covered by a shallow sea called the Baltic Basin. The sedimentary rocks (predominantly carbonates) comprising most of the island today were initially formed in this warm sea, and the relatively complete succession of rocks often contains fossil fragments and scales from early vertebrates, including heterostracans, anaspids, thelodonts, osteostracans, acanthodians, and a stem-osteichthyan.

7. 5. Wide-scope screening for contaminants of emerging concern in archived biota: Method development, suspect prioritisation, and non-target screening in a novel identification tool

   Author : Wiebke Dürig; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Environmental monitoring of hazardous chemicals in wildlife conventionally uses target screening for selected contaminants, but relatively few contaminants are moni-tored and knowledge of potentially hazardous contaminants of emerging concern (CECs) in wildlife is lacking. In this thesis, a non-target screening (NTS) method com-bined with temporal trend analysis was developed and applied as a prioritisation tool for identification of CECs in top predators, using high-resolution mass spectrometry (HRMS).
