Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="geb12021-sec-0001" sec-type="section"> <title>Aim</title> <p>One of the main gaps in the assessment of biodiversity is the lack of a unified framework for measuring its taxonomic and functional facets and for unveiling the underlying patterns.</p> </sec> <sec id="geb12021-sec-0002" sec-type="section"> <title>Location</title> <p>Europe, 25 large river basins.</p> </sec> <sec id="geb12021-sec-0003" sec-type="section"> <title>Methods</title> <p>Here, we develop a decomposition of functional β‐diversity, i.e. the dissimilarity in functional composition between communities, into a functional turnover and a functional nestedness‐resultant component.</p> </sec> <sec id="geb12021-sec-0004" sec-type="section"> <title>Results</title> <p>We found that functional β‐diversity was lower than taxonomic β‐diversity.
