New study finds that sewage release is worse for rivers than agriculture      (via sciencedaily.com)     Original source 

Sewage pollution, whether treated or untreated, was found to be the primary driver of increased nutrients, algae, and sewage fungus in rivers. Sewage discharge also radically altered plant, animal, and microbe communities, increasing the abundance of harmful species. Run-off from agriculture was also found to lower water quality and be particularly harmful for sensitive insect groups.

Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration      (via sciencedaily.com) 

• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.

Some spiders can transfer mercury contamination to land animals      (via sciencedaily.com) 

Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.
