A CHANGING ENVIRONMENT AND LARGE-SCALE POPULATION DYNAMICS
Many fish species inhabit wide distributions (on the order of 100's of miles) and/or undergo large-scale seasonal migrations. The environment across a species' range may differ substantially in physical dynamics (i.e. temperature) and biological dynamics (i.e. prey availability, quality). Investigating large-scale population dynamics in the context of environmental change is important because it can help us understand if certain portions of a population are impacted differently. This information is useful for both anticipating changes in ecosystems (i.e. under distribution shifts) and for fisheries management, as species traverse across multiple state and/or national boundaries. I primarily focus on using specimens collected across their distribution and measuring various energetic and reproductive parameters in the laboratory to assess potential intraspecific differences across a populations.
