Invasion biology: hypotheses and evidence.

Book cover for Invasion biology: hypotheses and evidence.

Description

This book, containing 18 chapters, combines the hierarchy-of-hypotheses (HoH) approach with hypothesis networks for invasion biology. This book aims to further develop the HoH approach by inviting critical comments (Part I), apply it to 12 major invasion hypotheses (Part II) and explore how it can be expanded to a hierarchically structured hypothesis network (Chapter 7 and Part III). It is importa...

Conclusions and outlook.

In Chapters 8-16, the hierarchy-of-hypotheses (HoH) toolbox has been applied in various ways. The results displayed as HoHs and additional bar graphs in most chapters, and as networks in Chapter 17, can now be used to identify knowledge gaps and promising paths for future research. We suggest some further steps that could be taken, making use of the data gathered for this book (which are freely available at www. hi-knowledge.org) and possible avenues for more general methodological advancements. To strengthen research in invasion biology, we specifically suggest four steps: (i) a more efficient provision and use of existing data and knowledge; (ii) a stronger focus on experiments or ideally research projects combining field studies with experiments; (iii) the development of sets of conceptually based 'case-sensitive' generalizations; and (iv) continuous integration of newly gained data and knowledge into a growing and developing atlas of invasion biology, which could potentially be expanded into an atlas of science. In this final chapter, we will first discuss how the chapters in Part II of the book made use of the HoH approach, what we think was achieved and which further methodological steps can be taken. The second section of this chapter, and final section of the book, will be an overall brief conclusion about the current state of invasion biology and possible ways forward.
