1. 1. Population demography’s potential effect on stoichiometry : Assessing the growth rate hypothesis with demography

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Alexander Blochel; [2017]
   Keywords : Demography; insect populations; stoichiometry; growth rate hypothesis;

   Abstract : The elemental composition within structured insect populations was tested by creating a new method to analyze how variables (survival, growth and fecundity) within a population matrix could potentially affect the stoichiometric regime of a structured population at steady state. This was done by focusing on if the growth rate hypothesis, which states that there is a linear relationship between an individual growth rate and the percent of phosphorus within the individual, works at a population level.

3. 2. Nutrient cycling by the herbivorous insect Chrysomela tremulae : Nutrient content in leaves and frass and measurements of ingestion, egestion and exuviation rates

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Sara Andersson; [2016]
   Keywords : Insect herbivory; nutrient cycling efficiencies; approximate digestibility; Chrysomela tremulae; increased C:N;

   Abstract : Insect herbivory on forest canopies strongly affects ecosystem nutrient cycling and availability in a variety of ways, e.g. by changing the quantity, quality and timing of nutrient input to forest soils. READ MORE
