Ecological resilience is essential for maintaining ecosystem services in an era of rapid global change, but successful attempts to operationalize it for managing ecosystems at risk have been limited. Clear formulation and application of ecological resilience concepts can guide ecosystem management so that it enhances the capacity of ecosystems to resist and recover from disturbances and provides adaptive space for periods of ecological reorganization. As originally defined, ecological resilience measures the amount of perturbation required to change an ecosystem from one set of processes and structures to a different set of processes and structures, or the amount of disturbance that …

The Effects Of Phosphate On The Metamorphosis Of Larval Western Barred Tiger Salamanders (Ambystoma Mavortium), Alexis Jean Polivanov
Department of Environmental Studies: Undergraduate Student Theses
This investigation will collect data to assist in determining if elevated aquatic phosphate levels affects the metamorphosis rate of larval western barred tiger salamanders (Ambystoma mavortium). Monoammonium phosphate fertilizers are being used on crops in Nebraska (NDA, 2017). This area lines up with the area the western barred tiger salamanders are disappearing from (Damme, 2018). Monoammonium phosphate is made up of nitrogen and phosphate. There have been several studies showing how nitrogen is harmful to amphibians such as this salamander (Griffis-Kyle, 2007) (Griffis-Kyle & Richtie, 2007), but there have not been many showing how phosphate affects amphibian’s metamorphosis …
