Q
Pond
Def
A
Shallow enough that light reaches the bottom throughout the pond.
(You will therefore potentially get root macrophytes throughout)
7
Q
Lake
Def
A
Deep enough so that there is an aphotic zone without rooted plants (and other zones)
8
Q
Osmoconformer
A
Body osmo = about the same as sea water and not found in estuaries or freshwater
9
Q
Osmoregulators
A
Active regulation of bodies osmolarity. But there is a cost
10
Q
Euryhaline
A
Able to osmoregulate across a wide range of conditions
11
Q
Stenohaline
A
Unable to osmoregulate (typically narrow range of tolerance)
12
Q
Adaptations for breeding success in FW envs from marine
X6
A
Lower fecundity Brood protection Larger egg size Abbreviated larval stage Higher tolerance to physio-chemical stress Little to no larval growth
