Hypothesis networks map major hypotheses. They structure and provide an overview of existing theory. Through the hierarchy-of-hypotheses approach (Jeschke et al. 2012, Heger et al. 2013, Heger et al. 2021), hypothesis networks can be hierarchically structured and connected to empirical studies and data. Thus far, we have created several hypothesis networks, two of them are available as hierarchical interactive networks that can be interactively explored (other hypothesis networks in invasion biology, which were created by other methods, are available in Enders et al. 2018 and Enders et al. 2019):

Invasion biology: large hypothesis network

Interactive, hierarchically structured network showing clusters of 39 invasion hypotheses, based on Enders et al. (2020) and the book Invasion Biology: Hypotheses and Evidence (Jeschke & Heger 2018). The hierarchical structure was achieved by applying the hierarchy-of-hypotheses approach. This tool is an extension of the smaller network with 12 hypotheses.

Invasion biology: hypothesis network book

An interactive visualisation tool that structures scientific evidence from ca. 1100 publications in a hierarchical network of 12 invasion hypotheses, based on the book Invasion Biology: Hypotheses and Evidence (Jeschke & Heger 2018).

Urban ecology: bipartite hypothesis network

Bipartite network of hypotheses in urban ecology from Lokatis et al. (2023), which are also available in a Wikiproject.

Invasion biology meets urban ecology: combined hypothesis network

Interactive visualisation of a combined hypothesis network covering both invasion biology and urban ecology (cf. Bernard-Verdier et al. 2023). This network combines hypotheses in invasion biology from Enders et al. (2020) with hypotheses in urban ecology from Lokatis et al. (2023).
