Investigating the comparison between bird diversity and apex aquatic predators in sub-alpine beaver ponds
Abstract
Predation of native salamanders by non-native trout in Colorado is a wildlife concern. Understanding the dynamics of how the different species interact is important. Cascade effects in the environment are caused by declines of species in a community. Birds, fish, and amphibians are deeply connected, therefore observing birds may help understand the ecosystem. Bird diversity is a crucial indicator to understand environmental changes and health. The research focused on the effects of different apex aquatic predators and the number of different bird species near beaver ponds. Point counts were conducted to observe birds visually and aurally for 15 minutes. The comparison between pond type and number of different species was significant, suggesting that different aquatic predators may affect bird communities. In future research, analyzing the tree canopy and pond depth would provide a useful distinction of each pond.
