Document Summary

Bio202: lecture 10: internal balance and environment: april 1, 2019. Don"t know much about environmental or biotic effects of expected changes, such as exploitation and contaminant accumulation. Increase in chloride trends in majority of freshwater lakes in. Study: wood frogs in gta areas have a higher parasite load and reduced anti-parasite response when exposed to road salt: wood frog = higher parasite load when exposed to road salt. Don"t have the anti-immune response to help them reduce the parasite load in non-salty water. & are more susceptible to human salting of the roads. Persistent organic pollutants (pops agriculture) in fish: tend to accumulate mainly in the brain and liver (the detoxifying organ) and some species are more sensitive (= can decease, or decrease production = can affect other animals) Know little of micro plastic (2-5mm) effects, esp. in freshwater environments. Gentoo penguin: more diverse in prey intake (generalists in diet)
