EXAMINING BIODIVERSITY OF ARCTIC FRESHWATER ECOSYSTEMS: DO CONSERVATION GOALS CHANGE WHEN LOOKING AT STRUCTURAL VERSUS FUNCTIONAL DIVERSITY?
Assessments of diversity in Arctic freshwaters generally focus on structural diversity, i.e., the number and composition of taxa at local or regional scales. However, changes in community structure may not result in alterations to ecosystem function if there is strong niche overlap among taxa, leading to functional redundancy. In Arctic freshwaters, where the number of taxa is often limited due to harsh environmental conditions, functional diversity and redundancy have not been widely studied, despite the importance of understanding how ecosystem function may change with a warming climate. Furthermore, northward range expansion may alter functional composition of these systems as taxa that occupy a different functional niche are introduced. In this presentation, we will provide an overview of the approach being taken in the ARCTIC-BIODIVER project to quantify functional diversity of Arctic freshwaters across the circumpolar region, including compilation of circumpolar trait data, selection of relevant traits, preliminary patterns of trait distribution along latitudinal gradients and a comparison to patterns in structural diversity of the circumpolar region.
