| Sammendrag: | This study concerns interaction between organisms. Such interactions are often studied
through organism abundances over periods of time (time-series). Time-series reflect both
internal (biological) and external (environmental) factors and the separation of these factors
from time-series is a non-trivial task.
The first two papers represent an introductory stage where a new approach to time-series
analysis is presented and where two-species interactions are explored with synthetic data
obtained from model simulations and lake plankton data. Paper 3 reports on time-series
analysis of an experimental ecological system in which interactions are studied in greater
detail. Paper 4 covers experiments testing the stability of demographic trade-offs in
microcosms. By doing nearly equivalent analyses within a range of “ecological realism” of
the time-series, this thesis puts the suggested method through a systematic test and explores
some basic assumptions in time-series analysis.
The first part of the thesis consists of a summary where this work is presented and discussed
in the context of current time-series analysis. The second part contains the four papers. |
