   Sammanfattning : This thesis aims to explore students’ argumentation and decision-making relating to authentic socioscientific issues (SSI). The ability to make informed decisions about socio scientific issues has been recognized to be an important element in science education to achieve the goal of scientific literacy. LÄS MER

5. 4. Food Web Ecology -- individual life-histories and ecological processes shape complex communities

   Författare :Martin Hartvig; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; food web; community ecology; community assembly; size-structure; life-history omnivory; ontogeny; trophic interactions; trait based model; topology; emergent organisation; size-spectrum;

   Sammanfattning : This thesis sets out a food web framework for size-structured populations. The framework enables an ecological approach to food web modelling as the individual life-history from birth, through maturation, and ultimately death is explicitly resolved with the use of bioenergetics based on individual body size.
