Where to Go<br />
Fourth Floor, Our Hudson Home, Microscopic Views<br />
What to Do<br />
• Observe <strong>the</strong> four slides, particularly <strong>the</strong> zooplankton<br />
(slide C) and algae (slide D). Can you see <strong>the</strong>se organisms<br />
in detail without <strong>the</strong> microscope?<br />
Consider This<br />
• Many aquatic species begin <strong>the</strong>ir life cycle as plankton. Several<br />
invasive species in this area arrived as plankton in <strong>the</strong> ballast<br />
water of ships and were discharged unknowingly in <strong>the</strong> harbor.<br />
• What measures can be taken to prevent <strong>the</strong> introduction of<br />
species <strong>that</strong> start life as microscopic plankton, almost invisible<br />
to our naked eyes?<br />
• What o<strong>the</strong>r species have stages in <strong>the</strong>ir life cycle <strong>that</strong> might<br />
share <strong>the</strong> same monitoring problem?<br />
• Many recreational boats are now responsible for spreading<br />
invasive species throughout different waterways. How does<br />
this spread occur, and how can it be prevented?<br />

O<strong>the</strong>r Things to Try<br />
• Read Benthic Banquet to see how pollution can accumulate in<br />
<strong>the</strong> food chain.<br />
