Towards an explicit spatial perspective of ecological networks in Canada
Ecological networks of species interactions are fundamentally realized in space. Yet, few studies are repeated in space and time due to the complexity of sampling both interactions and networks. In my thesis, I will develop three essential elements required to build an explicitly spatial perspective of ecological networks: draft predictions of networks accompanied by a quantification of uncertainty, sampling recommendations to improve our current predictions, and standardized variables for repeated network monitoring. Chapter 1 will use the recent metaweb of Canadian mammals and produce a spatial probabilistic version, which will return localized draft networks that allow propagating uncertainty. Chapter 2 will reuse the uncertainty output and generate recommendations for new sampling locations to reduce uncertainty in the models. Chapter 3 will consider how data should be collected in those locations and recommend standardized variables and indicators for repeated monitoring, which will become the Essential Biodiversity Variables for species interactions and ecological networks.
