Online Course – 3rd Edition

Embracing uncertainty: preserving gradual patterns when modelling species distribution diversity and change

January 17th-21st, 2022

This course will be delivered live online

This course will be taught using a combination of live (synchronous) sessions on Zoom, with tasks to be completed in between live sessions on the Slack platform.
The live sessions will be recorded and available to the participants for a limited period of time. However, attendance to the live sessions is required as this course is mostly hands-on.

Course Embracing uncertainty preserving gradual patterns when modelling species distribution diversity and changeCourse overview

Species occurrence data are always incomplete snapshots of actual species distributions, which are often elusive, dynamic and constantly changing. Predicting species distributions and how they may evolve is crucial for ecosystem management and conservation planning, but the intrinsic unpredictability that is inherent to living organisms prevents accurate categorical forecasts of species’ occurrence sites, or accurate delimitations of their distribution ranges.

Species distribution models are often applied, but their predictions are then typically converted to binary predictions of presence or absence, using artificial thresholds whose choice can have substantial impacts on the results, conclusions and recommendations arising from such studies. The problem is compounded when these models need to be combined to forecast species diversity patterns, range overlaps, and distributional changes such as range shifts, expansions or contractions.

In this course, we will:

1) Recognize the intrinsic uncertainty associated with all species occurrence data

2) Employ easy-to-use tools for formally dealing with this uncertainty using species distribution models, favourability, fuzzy logic, and an analogy with quantum physics

3) Obtain more realistic estimates of species distribution, diversity (including vulnerability and endemicity) and change, without using thresholds.

The course includes theoretical and practical sessions, which are carried out entirely in R. We will use R packages such as fuzzySim and modEvA to 1) model species distributions based on available occurrence records, and obtain favourability from species presence probability; 2) evaluate the predictive capacity of these models with a varied set of metrics that address different facets of model performance, including discrimination and calibration; and 3) incorporate natural uncertainty in the analysis of species distributions, avoiding thresholds and instead using fuzzy logic to assess potential diversity, vulnerability, endemicity, overlap and change in biogeographical communities.

We will provide plenty of example data for the practicals, but participants are also encouraged to bring their own species distribution data to analyse under our guidance.

REQUIREMENTS

Participants will need a computer with R installed, a good internet connection, and preferably a webcam to keep the live sessions as dynamic and interactive as possible. Basic knowledge of R is required.
