SETL Project: Monitor the Growth of Introduced Species

1
SETL ProjectMonitor the Growth of Introduced
Species
2
Non-Native Species

• Hundreds of new species arrive in the United
  States daily
• Survive and force their way into the ecosystem
• These introductions are exponentially increasing
  every year
• Non-native species are the second largest cause
  of biodiversity loss

3

• New introductions impact the environment,
  fisheries, and economy
• Some of the most widespread non-native species in
  New England are colonial tunicates, green fleece,
  and the Asian shore crab
• These are currently displacing native species,
  affecting their distribution and abundance
• Introduced species create a waterfall effect that
  creates unpredictable shifts in the basic
  environment

4
What Can We Do?

• Due to the many aspects of introduced species
  that cannot be predicted, it is important to know
  more about them
• We need to devise a method to determine the
  number and distribution of the known introduced
  species and monitor new introductions

Anemoon FoundationSETL Project

• Become part of a worldwide program initiated by
  Adriaan Gittenberger to monitor the growth of
  invasive species
• By 2009 the project will be in effect in
  temperate waters of every continent

SETL Materials

• Brick with holes
• PVC plate
• Washing/clothing line
• Cable ties
• 2 long and 4 short
• Electric Sanding Device
• Scissors
• Pliers
• Measuring Tape
• Electric Drill

8
Steps 1-3

• Steps 1-3
• Roughen one side of the plate with sandpaper.
  Drill 4 holes 3.3 cm (1.30 in.) and 5.5 cm (2.17
  in.) from each corner (see diagram).

9
Steps 4-6

• Step 4
• Pull a short cable tie through each pair of
  holes. (Use the pair of holes with a distance of
  7.4 cm (2.91 in.) make sure the two loose ends
  are not on the rough side of the plate).
• Step 5
• Attach the two ends of each cable tie. (Do not
  tighten them).
• Step 6
• Place brick between the two cable ties.

10
Steps 7-10

• Place two short cable
• ties around each side
• of the attached cable
• ties, then thread each
• one through one
• holes of the brick to
• the other side, around the second
• cable ties and attach.

11
Steps 11-15

• Step 11
• Tighten all the cable
• ties with pincers to
• firmly attach the brick
• to the plate.
• Steps 12-15
• Cut away excess ends
• of cable ties.

12
Steps 16-18

• Steps 16-18
• Pull long cable ties through each top corner hole
  of brick and thread both ties through one loop of
  the line. Close the ties, but do not tighten.

13
Steps 19-23

• Steps 19-23
• Cut away excess ends of cable tie. Hide
  connections of cable tie in holes of the brick.

14
Step 24

• Step 24
• Make sure the effective length between plate and
  the top end of line is 1 m. (3.28 ft.).

What do we expect to find?

• Fouling organisms animals and plants that
  attach to man-made structures like ships hulls
  or docks
• Early settlement organisms who are the first of a
  succession of species
• Natives, established introduced species, and
  maybe new non-natives

20
Potential Fouling Organisms

• Barnacles Mussels
• Hydroids
