  2. 1. 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.

  4. 2. Climate change time machine : Adaptation to 30 years of warming in the Baltic Sea

    Author : Friederike Ermold; Anssi Laurila; Jukka Jokela; Kerstin Johannesson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; thermal adaptation; evolution; Baltic Sea; Biotest Basin; ecological interactions; biological invasions; phenotypic plasticity; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Earth mean surface temperature has increased by 1 °C since the industrial revolution, and this has already had considerable effects on animal and plant species. Ecological responses to the warming climate – often facilitated via phenotypic plasticity – are ubiquitous. READ MORE

  5. 3. Geology, stratigraphy, and fossil vertebrates of Gotland, Sweden : a review

    Author : Oskar Bremer; Henning Blom; Per Ahlberg; Märss Tiiu; Jan Ove Ebbestad; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silurian; Gotland geology; Baltic Basin; extinction events; isotope excursions; atmospheric and oceanic cycles; early vertebrates; scale taxonomy; environmental preferences; vertebrate biozonation.; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : The Silurian limestones of Gotland, Sweden, and their exceptionally well-preserved fossils have attracted the interest of scientists for more than 200 years. The sedimentary rocks represent approximately 10 million years of time, and were deposited in a shallow, equatorial inland sea named the Baltic Basin. READ MORE

  6. 4. From the migrations of herders and farmers to the colonial era and the modern-day : Genetic inferences on African demographic history

    Author : Rickard Hammarén; Mattias Jakobsson; Carina Schlebusch; Torsten Günther; Luca Pagani; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; admixture; African demography; human evolutionary genetics; population structure; sex-biased admixture; Africa; population genetics; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Abstract : Africa is the birthplace of the human species and home to great linguistic, cultural, and genetic diversity. Despite this, the genetics of the peoples of the continent remains understudied. In this thesis, I apply population genetic approaches, to contribute to the knowledge of human demographic history in Africa. READ MORE

  7. 5. Latest Miocene – Early Pliocene Paleoclimate and Phytoplankton Productivity

    Author : Boris-Theofanis Karatsolis; Jorijntje Henderiks; Luc Beaufort; Uppsala universitet; []
    Keywords : Late Miocene; early Pliocene; IODP; paleoclimate; basin evolution; phytoplankton; paleoproductivity; Milankovitch cycles; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : Paper IPre-Quaternary paleoclimate studies in Australia mainly focus on terrestrial records from the southeastern part of the continent. IODP Expedition 356 drilled on the northwestern Australian shelf, yielding Miocene-Pleistocene paleoclimate records in an area where climate archives are scarce. READ MORE
