Invasion Biology [EPUB ebook] 
Hypotheses and Evidence

Invasion biology has many hypotheses, but it is largely unknown whether they are backed up by empirical evidence. This book fills that gap by (a) further developing a tool for assessing research hypotheses and (b) applying it to a number of invasion hypotheses, using the hierarchy-of-hypotheses (Ho H) approach. Part 1, an overview chapter of invasion biology will be followed by an introduction to the Ho H approach and short chapters of science theorists and philosophers that comment on the approach. Part 2 outlines the 30 invasion hypotheses and their interrelationships. Part 3 suggests future directions of invasion research.
