Abstract
Many teleosts exhibit intraspecific variation that correlates with differences in available resources and environmental conditions. We evaluated the extent of intraspecific variation in yellow perch, Perca flavescens, between two lakes (a mining-influenced lake vs. a spring-fed lake) that present differences in calcium availability, pH, and visibility. Previous studies demonstrated that these two lake populations have different predator escape kinematics, body morphologies, and vertebral material properties, leading us to hypothesize that the pattern of vertebral bone formation through remodeling was different since these two lake populations shared the same calcium concentrations in their vertebrae. In this study, we conducted a series of dissections of the vertebrae and used microCT scans to reveal detailed morphology of the vertebrae for interpopulation comparisons, as well as intrapopulation/intersegmental comparisons, in P. flavescens. We will discuss the implication of our findings.
