In wallace: A Modular Platform for Reproducible Modeling of Species Niches and Distributions

Component: Model Transfer

ORIENTATION

Frequently, research questions require the application (or “transfer”) of a model to a geographic region or time period different from those used to build it (e.g., for studies of invasive species or the effects of climate change). Component: Model Transfer allows certain functionalities for such transfers, as well as the means for assessing issues regarding environmental conditions not found in the space and time where the model was built (non-analog environments; Williams and Jackson 2007, Fitzpatrick and Hargrove 2009). Wallace currently allows users to transfer a model to: 1) another region (Module: Transfer to New Extent), 2) another time period (Module: Transfer to new time), or 3) a user-provided environment (Module: Transfer to User environment). Note: Transferring can also be known as a “projection”, but users should not confuse this with the GIS concept of geographic projections. Furthermore, at present Wallace provides some information characterizing the degree to which the environment in the spatial/temporal transfer differs from that used to make the model (Module: Calculate Environmental Similarity). For these functionalities, only one transfer can be displayed at a time, and Module: Calculate Environmental Similarity can only be run after a transfer has been made.
