LARVAL AMPHIBIAN DISTRIBUTION ACROSS INTERMITTENT STREAM POOLS IN THE FLINT HILLS
Climate change is expected to increase the frequency and severity of droughts and precipitation events. Intermittent stream pools in the Great Plains present an idealized replicated system to study the impacts of variable climatic conditions on the distribution of aquatic species including amphibians. We sampled 117 stream pools to investigate the effects of fish presence, stream vegetation, hydroperiod, connectivity, and pool volume on larval amphibian distribution and density in the Flint Hills of Kansas. Fish presence, pool volume, and pool connectivity all influenced the distribution of amphibians on the landscape (P < 0.05). In pools where amphibian larvae occurred (n=31), density(g/m3) was significantly influenced by stream vegetation and pool volume (P < 0.01). In the Great Plains, intermittent stream pools are the most abundant spawning habitat for amphibians. We sampled during a wet year (2020) and the results we found are likely to be variable year to year due to the variation in precipitation. Although more precipitation has the potential to increase the likelihood of larval amphibian presence, it also makes pools more susceptible to fish colonization due to increased connectivity.
