the river would have less water, so there would be less fish to catch
a mutation in a gene that does not affect the downstream genes in an operon. ie. a polar mutation is one that DOES affect the transcription or translation of genes in the same operon downstream of your gene of interest.
yes because black sea urchins are fished for their roe.

They reduce flow, and create a backpool which reduces flow downstream

Landslides caused by cutting trees affect the ecosystem by destroying habitat where many animals and even people live. The landslides actually change the contours of the land sometimes rerouting rivers.
There is no commercial fishing -- thus no 'over-fishing' -- in Antarctica based on the the Antarctic Treaty.
No
Tides affect fishing because they can provide plenty of fish for fishermen. For example, when the tide is moving, it is more productive and doesn't have slack. When there is less of a slack, then there will be more fishes in the surf.
