Abstract
The extent to which habitats are spatially heterogeneous, or "patchy" and the implications of this form of complexity for the organisms that live in them, are presently topics of considerable active research. The patch complexity within and around some montane meadow habitats in the Alps was defined and measured by calculating the fractal dimensions of mosaics created on a Geographical Information System. Results demonstrate that the meadows have extremely high fractal dimensions—indeed they are the most spatially complicated habitat mosaics that have been measured. Spatial variations in the fractal dimension itself correlate with observed patterns of species richness and abundance of syrphid flies (Diptera), a group of common flower-visiting insects in the area.
期刊介绍：
The Journal of Theoretical Biology is the leading forum for theoretical perspectives that give insight into biological processes. It covers a very wide range of topics and is of interest to biologists in many areas of research, including:
• Brain and Neuroscience
• Cancer Growth and Treatment
• Cell Biology
• Developmental Biology
• Ecology
• Evolution
• Immunology,
• Infectious and non-infectious Diseases,
• Mathematical, Computational, Biophysical and Statistical Modeling
• Microbiology, Molecular Biology, and Biochemistry
• Networks and Complex Systems
• Physiology
• Pharmacodynamics
• Animal Behavior and Game Theory
Acceptable papers are those that bear significant importance on the biology per se being presented, and not on the mathematical analysis. Papers that include some data or experimental material bearing on theory will be considered, including those that contain comparative study, statistical data analysis, mathematical proof, computer simulations, experiments, field observations, or even philosophical arguments, which are all methods to support or reject theoretical ideas. However, there should be a concerted effort to make papers intelligible to biologists in the chosen field.
