  1. 1. Population and Community Dynamics in Variable Environments

    University dissertation from Theoretical Ecology, Ecolgy Building, Lund University

    Author : Jörgen Ripa; Lund University.; Lunds universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dispersal; Moran effect; linear dynamics; synchrony; power spectrum; autocorrelation; extinction risk; population dynamics; environmental stochasticity; migration; stochastic modelling; Ecology; Ekologi;

    Abstract : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. READ MORE

  2. 2. Bloom dynamics and population genetics of marine phytoplankton - Community, species and population aspects

    University dissertation from Theoretical Ecology, Ecolgy Building, Lund University

    Author : Karolina Härnström; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; dynamics; Skeletonema marinoi; population genetics; resting stages;

    Abstract : Phytoplankton are the most important primary producers in the world’s oceans and coastal waters, accounting for nearly half of the global net primary production. Although they are such important organisms, little is known about the ecology and dynamics of phytoplankton. READ MORE

  3. 3. Species interactions govern evolutionary and ecological effects of population harvesting

    University dissertation from Department of Theoretical Ecology, Ecology Building, SE-223 62 Lund, Sweden

    Author : Anna Gårdmark; Lund University.; Lunds universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; population harvesting; species interactions; ecological community; Ekologi; Ecology; competition; predation; fisheries; spatial dynamics; maturation; population dynamics; life-history evolution; adaptation;

    Abstract : Harvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment.

  4. 4. Landscape Dynamics Spatial analyses of villages and farms on Gotland AD 200-1700

    University dissertation from Uppsala : Uppsala universitet

    Author : Gustaf Svedjemo; Uppsala universitet.; [2014]
    Keywords : HUMANIORA; HUMANITIES; Gotland; Archaeology; History; Historical maps; Roman Iron Age; Migration Period; Middle Ages; Village; Village formation; Farm; Settlement archaeology; Spatial analyses; GIS; Prediction modelling.; Gotland; Arkeologi; Historia; Historiska kartor; Romersk järnålder; Folkvandringstid; By; Bybildning; Gård; Bebyggelsearkeologi; rumsliga analyser; GIS; Geografiska informationssystem; prediktionsmodellering;

    Abstract : This dissertation deals with the long-term dynamics and fluctuations of settlements on Gotland for the period from AD 200 up until early modern times. The settlement structure on Gotland is most often described as very stable and consisting of solitary farms, established in the Iron Age. READ MORE

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

    University dissertation from Umeå : Institutionen för ekologi, miljö och geovetenskap. Umeå universitet

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

    Abstract : 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. READ MORE
