  1. 1. Effects of size-dependent predation and competition on population and community dynamics

    Detta är en avhandling från Umeå : Institutionen för ekologi, miljö och geovetenskap. Umeå universitet

    Författare :Karin Nilsson; Umeå universitet.; [2010]
    Nyckelord :size-structure; cannibalism; resource competition; predation; emergent facilitation; population regulation; population dynamics; overcompensation; density-dependence; cycles; zooekologi; Animal Ecology;

    Sammanfattning : Most animals grow substantially during their lifetime and change in competitive ability, predatory capacity and their susceptibility to predation as they grow. This thesis addresses the implications of this on regulation and dynamics within populations as well as between population interactions. LÄS MER

  2. 2. Population Genetics of Human Genomic Elements

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Thijessen Naidoo; Uppsala universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population genetics; human genome; functional elements; natural selection; pseudogenes; loss-of-function; gene regulation; Y chromosome; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : The genomes of living organisms are composed of a multitude of functional units, which interact with each other and their environment in a highly regulated fashion, to facilitate the expression of an enduring (and evolving) phenotype. Several approaches have emerged in the effort to identify these functional units and explore their activities. LÄS MER

  3. 3. Effects of Great Cormorant Predation on Fish Populations and Fishery

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Henri Engström; Uppsala universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Great Cormorant; Phalacrocorax carbo sinensis; predation; population regulation; diet; diet preferences; eel; behavioural responses; bird-fishery conflicts; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; populationsbiologi; Population Biology;

    Sammanfattning : The strong increase in number of Great cormorants Phalacrocorax carbo in Sweden in recent years has led to conflicts - particularly with fishery. This thesis focuses on the possible effects of cormorant predation on fish populations. LÄS MER
