Geodiversity–biodiversity relationships in northern environments

A long-term challenge in biodiversity research has been the establishment of robust methods for cost-effective targeting of conservation actions.

The concept of geodiversity has recently been expressed as a novel complementary and potentially useful means to explore biodiversity.

Geodiversity refers to the variability of the Earth’s surface materials, forms, and physical processes at different scales. In general, there is a lack of studies where geodiversity has been systematically inventoried across environments and scales. Importantly, the potential of geodiversity as a surrogate of biodiversity has not been assessed using comprehensive biological and geodiversity data sets.

Thus, our fundamental goal is to promote biodiversity monitoring by examining geodiversity and its relationship to biodiversity in boreal and subarctic landscapes. This research may produce answers to several scientifically important questions in geodiversity mapping and biodiversity assessment by revealing the most suitable measures of geodiversity for biodiversity assessments, and by improving the performance and robustness of biodiversity models.
