1. 16. Variation in age and size at maturation in two benthic crustaceans in the Gulf of Bothnia

   Författare :Kjell Leonardsson; J. Ekman; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Age at maturation; alternative prey; Bergmanris rule; cannibalism; growth; life-history theory; mortality; Mvoxocephalus quadricornis; poikilotherm; Pontoporeia affinis; population dynamics; risk- taking behaviour; Saduria entomon; size at maturation; temperature;

   Sammanfattning : The thesis deals with variation in age and size at maturation in Saduria entomon and Pontoporeia affinis along a depth gradient in the Gulf of Bothnia, Sweden. I have analysed at what sizes and ages animals should mature in relation to growth and mortality conditions. LÄS MER

   Sammanfattning : Serum amyloid A protein (SAA) is an acute phase protein that has recently gained increasing interest as a potential marker for disease and treatment monitoring. We investigated SAA and CRP levels in (a) patients with various common infectious diseases (n=98), (b) patients with pyelonephritis (n=37) versus patients with cystitis (n=32), (c) healthy individuals of varying ages (n=231), (d) very immature newborn infants with or without nosocomial infections (NIs) (n=72) and (e) patients with bacterial infections treated with cefuroxime (n=81).

4. 18. Tree-rings and climate - Standardization, proxy-development, and Fennoscandian summer temperature history

   Författare :Jesper Björklund; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tree rings; Fennoscandia; summer temperature; maximum latewood density MXD ; blue intensity BI ; standardization;

   Sammanfattning : Instrumental meteorological observation are too short for trying to estimate climate change and variability on multi-decadal and centennial time-scales, and when trying to evaluate the response of the climate system to human influence, such as raised concentrations of green house gases (GHG), altered land-use, black carbon etc. To access information about the climate system predating instrumental observations, reliable proxy records (natural archives) are necessary.

5. 19. Micro- and macroevolutionary aspects of body size diversification and thermal adaptation in insects

   Författare :John Waller; Evolutionär ekologi; []
   Nyckelord :Evolution; body size; Insects; dragonflies; damselflies; Odonata; Comparative methods; fossils;

   Sammanfattning : Body size and body temperature are the two most important traits in biology. In this thesis I show how these twovariables have shaped the evolution of insects over the last 300 million years. LÄS MER

7. 20. Temperature- and body size scaling: effects on individuals, populations and food webs

   Författare :Max Lindmark; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Climate warming impacts organisms directly through changes in their physiology. Empirical evidence suggest warming has already led to changes in growth, body size, population and community size-structure of natural populations. However, it is difficult to understand the underlying mechanisms from observational data alone. LÄS MER
