  2. 1. Birds and butterflies at the forest-farmland interface

    Author : Dafne Ram; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conservation; Monitoring; Forestry; Grassland butterflies; Farmland birds;

    Abstract : Land-use change is one of the greatest threats to biodiversity. Through intensification of land-use, the agricultural landscape has become more homogenous and a result, many species associated with traditional farmland or other semi-natural open habitats have declined. READ MORE

  4. 2. Birds as a Model for Comparative Genomic Studies

    Author : Axel Künstner; Hans Ellegren; Hanna Johannesson; Chris Ponting; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Birds; Selection; Gene expression; Sequence evolution; Next-generation sequencing; Comparative genomics; Molecular evolution; Genomics; Substitution Rates; Non-coding DNA; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Comparative genomics provides a tool to investigate large biological datasets, i.e. genomic datasets. In my thesis I focused on inferring patterns of selection in coding and non-coding regions of avian genomes. READ MORE

  5. 3. Effective conservation of biodiversity and ecosystem services in agricultural landscapes

    Author : William Sidemo Holm; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem services; agri-environmental measures; cost-effectiveness; conservation;

    Abstract : Agricultural land use is a major driver of biodiversity losses and changes in ecosystem services. Thus, for the sake of both humans and wild organism per se, effective strategies that enable both agricultural production and conservation of biodiversity and ecosystem services are urgently needed.

  6. 4. On the importance of farmland as stopover habitat for migrating birds

    Author : Juliana Dänhardt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conservation; bird migration; agriculture; stopover ecology; Golden plover; Pluvialis apricaria; landscape heterogeneity; organic farming; food availability; earthworms;

    Abstract : Agricultural intensification has led to dramatic population declines among many farmland bird species. Negative effects of intensive farming in terms of decreased local habitat quality or structural simplification of farmland landscapes have reduced both reproductive outcome and winter survival of many species.

  7. 5. Behavioural differences and genetic relationships between four captive populations of red junglefowl (Gallus gallus) : possible implications for conservation

    Author : Jennie Håkansson; Linköpings universitet; []
    Keywords : Red junglefowl; behavioural differences; genetic relationships; captive populations; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Conservation of species is to a large extent carried out by zoos where animals are kept in small populations under protected conditions. The ultimate goal of such ex situ conservation programs is to eventually reintroduce the animals into natural habitats to provide support for the survival of the species. READ MORE
