  1. 21. Plant Population Dynamics of Dodonaea angustifolia and Olea europaea ssp. cuspidata in Dry Afromontane Forests of Ethiopia

    Författare :Tesfaye Bekele; Ingvar Backéus; Karin Bengtsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Demography; Dodonaea angustifolia; Elasticity; Establishment; Germination; Natural regeneration; Olea europaea ssp. cuspidata; Population structure; Recruitment; Seed bank; Survival; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecological Botany; Ekologisk botanik;

    Sammanfattning : Human disturbance has led to excessive deforestation and to a very limited forest cover in the Afromontane zone of Ethiopia, which forms a large part of the country. Thus urgent conservation measures are required to ameliorate the situation. LÄS MER

  3. 22. Genome mapping of the horse

    Författare :Gabriella Lindgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Horse; microsatellites; linkage analysis; FISH; Type I markers; BAc library; Y chromosome; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Evolutionary Genetics; evolutionär genetik;

    Sammanfattning : Our ability to map and sequence whole genomes is one of the most important developments in biological science. It will provide us with an unprecedented insight into the genetic background of phenotypic traits, such as disease resistance, reproduction and growth and also makes it feasible to study the processes of genome evolution.

  4. 23. Early development of the olfactory placode and early rostrocaudal patterning of the caudal neural tube

    Författare :Esther Maier; Lena Gunhaga; Fernando Giraldez; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory placode; caudal neural tube; Wnt; FGF; RA; BMP; Notch; patterning; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The development of the nervous system is a complex process. Cell divisions, cell differentiation and signalling interactions must be tightly regulated. To comprehend the mature nervous system, we have to understand its assembly during development. LÄS MER

  5. 24. Early Rostrocaudal Patterning of the CNS

    Författare :Ulrika Nordström; Thomas Edlund; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CNS development; neural patterning; neural specification; Wnt; FGF; RA; Isthmic organizer; motor neurons; rostrocaudal patterning.; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : The transformation of an initially uniform population of epiblast cells into an intricately complex central nervous system (CNS) is one of the most fascinating processes during embryonic development. Presumptive neural cells are initially specified as cells of forebrain character. LÄS MER

  7. 25. Disturbed sleep and emotion : a developmental perspective

    Författare :Nanette S. Danielsson; Steven J Linton; Markus Jansson-Fröjmark; Børge Sivertsen; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sleep disturbance; emotion dysregulation; catastrophic worry; sleep-onset; partial sleep deprivation; neuroticism; depressive symptoms; Psykologi; Psychology;

    Sammanfattning : Sleep disturbances are not only defining features, but also diagnostic criteria for most psychiatric disorders. Recently, researchers have proposed a theoretic role for sleep disturbances in emotion dysregulation, subsequently linking neurobiological processes and psychopathology. LÄS MER
