Non-native Cyprinella venusta (Blacktail Shiner) are known to occur in Truman Reservoir in Missouri. In 2017, we documented hybridization between C. venusta and native C. lutrensis (Red Shiner) within the reservoir. The goal of this study was to quan

Egg size variation among 16 Gulf Coast populations of Cyprinella venusta, the Blacktail Shiner, previously was shown to be significantly correlated with annual stream runoff. In this study, we examined egg size across multiple years and seasons in a

Unstable hybrid swarms that arise following the introduction of non‐native species can overwhelm native congeners, yet the stability of invasive hybrid swarms has not been well documented over time. Here, we examine genetic variation and clinal sta

The independent effects of in-stream structure (ISS) and fish foraging on stream properties have been well documented, but few studies have explored the interactive effects of ISS and fishes on streams. Herein, we tested the independent and interacti

The availability of water is becoming more variable as flow regime alterations intensify both locally and on a global scale. This pattern has been observed in the tributaries of the central Chattahoochee River System as water withdrawal and natural d

In order for an acoustic signal to be an effective source of communication, the signal must be successfully detected and interpreted by the intended receiver. One potential barrier to acoustic communication is background noise. Lotic systems contain

Hybridization is more common in actinopterygian fishes than any other group of vertebrates. This is especially true for members of the family Cyprinidae; for example, Hubbs found 68 different combinations of inter-generic and intra-generic hybridizat

Summary Environmental degradation can result in the loss of aquatic biodiversity if impairment promotes hybridisation between non-native and native species. Although aquatic biological invasions involving hybridisation have been attributed to elevate

Performance-related variation in fitness can manifest as morphological responses to ecological and evolutionary pressures. Eco-morphological studies often utilize stark binary comparisons, such as lentic to lotic populations of freshwater fishes, to

We examined survival, competition, and recruitment among cyprinids that were subjected to interspecific and intraspecific competition and chronic heat stress in large, outdoor experimental streams. The study was conducted in 2011 during the hottest s
