A new composite abundance metric detects stream fish declines and community homogenization during six decades of invasions

Aim We developed a new technique, utilizing species‐specific counts of individuals from historical fish community samples, to examine landscape‐level, spatio‐temporal trends in relative abundance distributions. Abundance‐based historical distribution analyses are often plagued by data comparability...
