  2. 11. Divergence, selection, demographic history and conservation genomics of sibling bird species in boreal forest in Northern Eurasia and the Qinghai-Tibetan Plateau

    Author : Kai Song; Jacob Höglund; Yue Hua Sun; Peter Halvarsson; Juha Merilä; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sichuan Jay; Siberian Jay; Chinese Grouse; Hazel Grouse; genomics; demographic history; ROH; genetic load;

    Abstract : I used two pairs of sibling boreal forest bird species to study divergence, selection, demographics, and conservation in northern Eurasia and the Qinghai-Tibetan Plateau at the microsatellite level (chapter 1) and whole genome level (chapters 2, 3, 4 and 5). In chapter 1, which is the first study to describe genetic diversity of the Sichuan Jay, I used microsatellite markers to estimate genetic differentiation in Sichuan Jay and Siberian Jay populations.

  4. 12. Essays on demographic factors and housing markets

    Author : Marie Heiborn; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Abstract : This thesis consists of four essays on demographic variables and housing markets.Essay I analyses the impact of demographic changes on housing demand. A demographic demand variable is constructed out of the age structure of housing demand and the age composition of the population. READ MORE

  5. 13. Demographic History and Adaptation in African Populations

    Author : Mário Vicente; Carina Schlebusch; Mattias Jakobsson; Lluis Quintana-Murci; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; African demography; human evolutionary genetics; population structure; population admixture; genetic adaptation;

    Abstract : Africa is the continent where modern humans originated and yet, African demographic history remains largely unknown. Through analyzing the genetic composition of extant and extinct individuals, it is possible to reveal signals of past demographic history and adaptation. READ MORE

  6. 14. Divergence, admixture and continuity in the human past : Demographic inference using ancient and modern genomes

    Author : James McKenna; Mattias Jakobsson; Per Sjödin; Ida Moltke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human evolution; population genetics; ancient genomes; population continuity; divergence; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Abstract : Demographic forces shaping the genetic variation we observe today can include population divergences, admixture events and continuity through time. The advancement of high-throughput sequencing technologies, together with developments in molecular and bio-informatics methods, mean the number of ancient genomes available for inference has risen steeply.

  7. 15. Shared practices : social networks and fertility decline during the Swedish demographic transition, 1850-1950

    Author : Johan Junkka; Sören Edvinsson; Angélique Janssens; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; historical demography; fertility transition; social interaction; social network; voluntary associations; historia; History;

    Abstract : This thesis studies how social interactions influenced the fertility decline during the Swedish demographic transition between 1850 and 1950. This, to gain insights into how and why norms and values affected married couples' birth control practices, and how this shaped the fertility decline. READ MORE
