2020 Healy et al., Remarkable Response of Native Fishes to Invasive Trout Suppression Varies with Trout Density, Temperature, and Annual Hydrology
ABSTRACT: Recovery of imperiled fishes can be achieved through suppression of invasives, but outcomes may vary with environmental conditions. We studied the response of imperiled desert fishes to an invasive brown (Salmo trutta) and rainbow trout (Oncorhynchus mykiss) suppression program in a Colorado River tributary, with natural flow and longitudinal variation in thermal characteristics. We […]

2014 Yackulic, Yard, Korman and Van Haverbeke, A Quantitative Life History of Endangered Humpback Chub that Spawn in the Little Colorado River, Variation in Movement, Growth, and Survival
While the ecology and evolution of partial migratory systems (defined broadly to include skip spawning) have been well studied, we are only beginning to under- stand how partial migratory populations are responding to ongoing environmen- tal change. Environmental change can lead to differences in the fitness of residents and migrants, which could eventually lead to […]
