Predator And Abiotic Effects On Hatching Phenotype And Survival Of Arboreal Frog Eggs With Implications For Phytoplankton, Jessica Hite

Theses and Dissertations

Historically studies have focused on either the terrestrial or aquatic environments independently. However, these systems are inherently linked through numerous pathways including organisms with complex life cycles. Both abiotic factors and predators of these organisms can influence connections by changing the number of prey moving across habitat boundaries and by changing the phenotype of prey. When the focal organisms are primary consumers, these effects may have important implications for ecosystem processes. My study investigated how terrestrial predators and abiotic factors affect the number and phenotype of herbivorous tadpole inputs into a tropical forest pond. I found that predators and abiotic …
