4. 2. Ecology of zooplankton communities: climate, dormancy, and benthic-pelagic coupling

   Author : Mikael Gyllström; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Marinbiologi; limnologi; akvatisk ekologi; limnology; Hydrobiology; marine biology; aquatic ecology; phytoplankton; temporal stability; recruitment; seasonal succession; environmental cues; diapause; shallow lakes; predation; enrichment; climate; temperature;

   Abstract : This thesis describes how influences, such as top down and bottom up forces, shape zooplankton communities in shallow lakes. I have also extended the traditional food-web theory by investigating the effects of climate on total biomass, taxonomic composition, and temporal properties of zooplankton communities. READ MORE

5. 3. On the Effects of Blood Parasites in Wild Birds

   Author : Peter Halvarsson; Jacob Höglund; Staffan Bensch; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atoxoplasma; avian malaria; coccidia; Gallinago media; Haemoproteus; Leucocytozoon; parasite prevalence; Passer montanus; Plasmodium; recapture mod-els; survival; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

   Abstract : Coccidian and haemoatozoan parasites are commonly occurring endo-parasites in wild birds and prevalence can vary among species and populations. In addition to prevalence studies, parasites are often used to investigate effects on life history traits. READ MORE

6. 4. Recruitment and distribution patterns of plants in Swedish semi-natural grasslands

   Author : Åsa Eriksson; Brita Svensson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant Ecology; växtekologi;

   Abstract : Semi-natural pastures with different histories of management are nowadays the main remnants of the traditional agrarian landscape in southern Sweden. The aims of this thesis were to investigate the importance of features of the present-day landscape and its management history for species distribution and abundance patterns in Swedish semi-natural pastures, with a particular focus on factors affecting recruitment processes.

7. 5. Quantitative genetic variation in declining plant populations

   Author : Maarten Ellmer; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Saxifraga granulata; Briza media; Nigella degenii; bottleneck; Inbreeding depression; founder effects; drift; quantitative genetic; diversifying selection; habitat fragmentation; small populations;

   Abstract : The ecological and genetic effects of habitat fragmentation are an issue of major concern in current conservation biology. Habitat fragmentation results in smaller habitat areas and as a consequence smaller and more isolated populations. Many habitats have become fragmented through human activities such as forestry and agricultural development. READ MORE
