Freshwater fish diversity is harmed as much by selective logging in rainforests as they are by complete deforestation, according to a new study.
Researchers had expected the level of damage would rise depending on the amount of logging and were surprised to discover the impact of removing relatively few trees.
[...] Lead author Clare Wilkinson, from the Department of Life Sciences at Imperial, said: "That such a small change can impact fish biodiversity is shocking and worrying. We expected to see a gradient from least affected in the selectively logged areas, to heavily impacted for the streams in oil palm plantations. Instead, we saw almost the same level of fish biodiversity loss in all altered environments."
[...] Researchers believe the reasons for these dramatic changes are likely to be down to a range of factors that affect stream habitats when trees are lost. Trees provide shade, creating cooler patches of stream that many fish need to spawn. Older, taller trees provide more of this shade, but they are the ones usually removed in selective logging. Leaf litter from these trees also helps to keep the streams cool and to concentrate food sources.

Ahhh, you must be one of those sad little dweebs who think that it's perfectly fine for any organism except humans to eat other animals. Live with it. We're nothing special, just a hairless ape with delusions of grandeur. Some more deluded than others.
And, yes, most conservationists who do any actual work (not just pissing and moaning) have always been fishermen and hunters. Nobody wants their favorite pastime fucked up by inconsiderate shitheads.
My rights don't end where your fear begins.
