Managing multiple uncertainties in species distribution modelling
Aim
We present a methodology to address multifaceted uncertainties in species distribution models (SDMs), enhancing their robustness and providing vital insights to inform management and conservation decisions. Data uncertainties, including positional inaccuracies in historical data and absences in survey data that could be attributed to anthropogenic disturbances rather than habitat unsuitability, can compromise SDM predictions, risking the efficacy of resultant conservation strategies.
Location
While the concepts and methodologies presented hold global applicability, our case study is situated in and around the Negev Desert of southern Israel and the Palestinian West Bank, focusing on the critically endangered Be'er Sheva fringe-fingered lizard (Acanthodactylus beershebensis) that is endemic to this area.
Methods
Utilizing calculated combinations of reliable and uncertain datasets, we created diverse dataset scenarios. Pre-development distribution and habitat requirements were estimated for each scenario using a blend of statistical and machine-learning algorithms in R. Additionally, a combined scenario was modelled using hierarchical model ensembles to effectively weight data by reliability.
Results
Our innovative approach produces more robust models and reveals the impact of uncertain datasets on model predictions. Incorporating potential anthropogenic absences led to erroneous model conclusions, particularly when historical data exclusion occurred—a practice often implemented in the pursuit of model robustness.
Main Conclusions
Uncertainties in SDMs can yield incorrect conclusions, imperilling conservation efforts. Initiated by land managers, our work actively informs conservation practices. The study's global relevance provides an approach for addressing real-world challenges in estimating species distributions, advancing the application of conservation science.
期刊介绍:
Diversity and Distributions is a journal of conservation biogeography. We publish papers that deal with the application of biogeographical principles, theories, and analyses (being those concerned with the distributional dynamics of taxa and assemblages) to problems concerning the conservation of biodiversity. We no longer consider papers the sole aim of which is to describe or analyze patterns of biodiversity or to elucidate processes that generate biodiversity.
