Fuzzy logic to address gradual patterns in species distribution and diversity (FLDD01)

11th May 2020 - 14th May 2020

£275.00 - £530.00

Course Overview:

Live beings are constantly in motion and occur with varying frequency across space. Hence, categorical occurrence maps are always incomplete and oversimplified representations of species’ actual distributions. Analyses that build on such categorical data, such as most diversity, overlap and (dis)similarity indices, overlook important gradations in species occurrence. Fuzzy logic is a valuable tool to formally address the locational uncertainty and gradual variations that characterize biodiversity patterns. This course will show how fuzzy logic can be incorporated in ecological analyses to improve the portrayal, understanding and prediction of species distribution patterns, with implications on (macro)ecological interaction, global change, biodiversity and biotic regionalization studies. We will work with a set of species distribution modelling methods that derive presence probability values (e.g. logistic regression, generalized additive models, tree-based classification and regression methods), which can be mathematically converted to fuzzy membership values. We will then see how these values allow more direct comparisons across species, regions and time periods. Finally, we will see how diversity and (dis)similarity indices, which normally require binary presence-absence data, can be generalized to work with fuzzy (degree of) occurrence data for both species and regions.

Intended Audience

The course is aimed at anyone (academic, government or industry) with an interest in analysing occurrence and diversity patterns of species and/or lineages.
