19 views9 pages

Document Summary

Environmental toxicity testing continued: focus: ecotoxicity testing. Multispecies toxicity tests: limnocorrals, artificial streams, field surveys, biomonitoring, experimental lakes, watersheds. Use of transplanted organisms as sentinels in the environment. ** field survey = wild animals in wild original environment. ** biomonitoring = animals into environment of interest: contamination of source waters is usually episodic, therefore monitoring must be continuous and time-relevant . Example: early life stage (els) salmonids: freshwater species, rainbow trout, cutthroat trout, model lab species, rt genome sequenced, commercially significant. Laboratory control: quality control measure, monitor stream temperature & mimic in lab, 4 l test volume. For exam, state what"s on the x-axis and y-axis: a and b = significantly different. If all letters are the same, then there"s no difference. In situ field studies: expression cluster analysis reveals distinct gene patterns. Laboratory and field expression patterns formed separate expression clusters. Fewest differences in gene expression between water control and meoh control.
