Slime proves valuable in developing method for counting salmon in Alaska

Scientists have published a novel method for counting Pacific salmon – analyzing DNA from the slime the fish leave behind in their spawning streams.

Trees’ enemies help tropical forests maintain their biodiversity, study finds

Scientists have long struggled to explain how tropical forests can maintain their staggering diversity of trees without having a handful of species take over – or having many other species die out. The answer, researchers say, lies in the soil found near individual trees, where natural “enemies” of tree species reside. These enemies, including fungi and arthropods, attack and kill many of the seeds and seedlings near the host tree, preventing local recruitment of trees of that same species.
