All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Historically, cities were established in close proximity to the richest agricultural lands and freshwater resources. In tropical islands, urbanization occupies a large percentage of land use along streams and rivers and strongly affects the biota and habitat quality. I studied freshwater decapod population and community dynamics in tropical streams of Puerto Rico across human and elevational gradients. I found that: 1) streams with less urbanization had higher decapod species richness and population sizes than the highly urbanized streams; 2) changes in the food webs in the streams are the result of the influence of changes in land use and environmental …
