We assigned six life history traits - fecundity, longevity, maturation age, maximum total length, parental care, and spawning season duration - to each fish species. Decreaser species were significantly smaller in size and shorter-lived with reduced fecundity and shorter spawning seasons compared to increaser species. Cluster analysis of traits revealed correspondence with a life history model defining equilibrium (low fecundity, high parental care), opportunistic (early maturation, low parental care), and periodic (late maturation, high fecundity, low parental care) end-point strategies. Nearly 50% of decreaser species were associated with an intermediate opportunistic-periodic strategy, suggesting that abiotic factors such as habitat specialization and streamflow alteration may serve as important influences on life history traits and strategies of decreaser species. In contrast, the percent of increaser species among life history strategy groups ranged from 21 to 32%, suggesting that life history strategies of increaser species were more diverse than those of decreaser species. This study highlights the utility of linking life history theory to biodiversity to better understand mechanisms that contribute to fish species distributions in the eastern U.S. Springer Science+Business Media Dordrecht (outside the USA), 2014 Life history traits nationallicence Life history strategies nationallicence Predictive models nationallicence Biodiversity nationallicence Meador Michael U.S. Geological Survey, 12201 Sunrise Valley Drive, MS 413, 20192, Reston, VA, USA aut Brown Larry U.S. Geological Survey, 6000 J Street, 95819, Sacramento, CA, USA aut Environmental Biology of Fishes Springer Netherlands 98/2(2015-02-01), 663-677 0378-1909 98:2<663 2015 98 10641 https://doi.org/10.1007/s10641-014-0304-1 text/html Onlinezugriff via DOI BK010053 XK010053 XK010000 Metadata rights reserved Springer special CC-BY-NC licence nationallicence 1 research-article jats NATIONALLICENCE NATIONALLICENCE NL-springer NATIONALLICENCE 856 40 https://doi.org/10.1007/s10641-014-0304-1 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Meador Michael U.S. Geological Survey, 12201 Sunrise Valley Drive, MS 413, 20192, Reston, VA, USA aut NATIONALLICENCE 700 1- Brown Larry U.S. Geological Survey, 6000 J Street, 95819, Sacramento, CA, USA aut NATIONALLICENCE 773 0- Environmental Biology of Fishes Springer Netherlands 98/2(2015-02-01), 663-677 0378-1909 98:2<663 2015 98 10641
