  2. 6. Variation in age and size at maturation in two benthic crustaceans in the Gulf of Bothnia

    Author : Kjell Leonardsson; J. Ekman; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 9. Thermal adaptation along a latitudinal gradient in damselflies

    Author : Viktor Nilsson-Örtman; Frank Johansson; Karl Gotthard; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Growth rate; metabolic theory of ecology; universal temperature dependence; environmental gradients; thermal performance; thermal sensitivity; environmental variability; optimality theory; life history; acclimation; size structure; competition; cannibalism; intraguild predation;

    Abstract : Understanding how temperature affects biological systems is a central question in ecology and evolutionary biology. Anthropogenic climate change adds urgency to this topic, as the demise or success of species under climate change is expected to depend on how temperature affects important aspects of organismal performance, such as growth, development, survival and reproduction.

  7. 10. Ontogenetic bottlenecks : effects on intraguild predation systems and ecosystem efficiency

    Author : Birte Reichstein; Lennart Persson; André M. De Roos; Priyanga Amarasekare; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mixed interactions; cannibalism; life-history omnivory; ontogenetic niche shift; biomass overcompensation; biomass production; ontogenetic asymmetry; indirect effects; biology; biologi; zooekologi; Animal Ecology;

    Abstract : Size-dependent differences between individuals in size-structured organisms have fundamental effect on population and community dynamics. Intraguild predation (IGP) is one specifically interesting constellation that often arises when two size-structured populations interact. READ MORE
