Macrofauna

Research Group: Rose Long, George Tang, Brendan McVeigh and Tyler Stetson

OBJECTIVE: TO FIND CORRELATION BETWEEN SPECIES DIVERSITY AND HABITAT QUALITY

TESTS PERFORMED:

pH TEST: THIS TESTS THE ACIDITY OF THE WATER. EACH SPECIES HAS A DIFFERENT TOLERANCE FOR THE PH LEVEL OF THE WATER. (7 IS NEUTRAL, HIGHER THAN 7 IS BASIC AND LOWER THAN 7 IS ACIDIC)

DISSOLVED OXYGEN: THIS TESTS THE AMOUNT OF OXYGEN THERE IS PRESENT IN THE WATER. SOME SPECIES REQUIRE MORE OXYGEN THAN OTHERS.

CONDUCTIVITY: THIS TEST MEASURES THE AMOUNT OF PARTICLES IN THE WATER. HIGHER CONDUCTIVITY MEANS MURKIER WATER, AND LOWER CONDUCTIVITY MEANS CLEARER WATER.

TEMPERATURE: DIFFERENT SPECIES LIVE AT VARYING TEMPERATURES.
