“…The biological traits for a given taxon may include, for example, the number of generations per year, the ability to enter a state of diapause, and the ability to burrow into the streambed to obtain food, seek refuge from predators, or escape low-flow conditions (Beˆche and Resh, 2007a, b). Biological traits of benthic-macroinvertebrate communities in Mediterranean-climate regions have been shown to be affected by long-term climate variability (Beˆche et al, 2006;Beˆche and Resh, 2007a, b;Bonada et al, 2007a, b;Lawrence et al, 2010) and seasonal differences (Mouthon and Daufresne, 2006;Cordellier and Pfenninger, 2008;Spooner and Vaughn, 2008;Clausnitzer et al, 2009;Hering et al, 2009).…”
