(** Throughout this section, click on the upper left icon to return to the Activities Main page **) Habitat Hypotheses Activity What do you know about how things work together in the river? Match these "if-then" statments to make hypotheses about the interrelationships in the river. Draw lines which connect the "if" statements with all possible "then" statements. You should be able to see how the many elements of salmon habitat are connected. Do the connections you hypothesized make sense? Why? If the river is too polluted then the salmon eggs cannot not hatch. If the river floods then the salmon cannot survive. If there is a drought then the salmon cannot spawn. If the temperature of the river gets too warm then the water gets too warm. If there is no vegetation along the river banks then the salmon cannot get enough oxygen. Now finish these hypotheses yourself: If there is a log jam in the river then... If there is heavy weed growth then... If there is a dam on the river then... Top of page.
