- A third of the tropical plants in Africa are threatened with extinction according to the IUCN's latest assessment. The information available for plants is less complete than for birds or mammals.
- All but one of the species listed under the Endangered Species Act face threats from climate change, but climate response has not been included in the recovery plans for most species.
- Conserving wildlife that disperse seeds is key to using forests as carbon sinks.
- Scientists are looking at fossil oysters to gauge what a health Chesapeake would look like.
- A tiny population of the endangered St. Francis Satyr persists on the Fort Bragg artillery range, and scientists are starting to build backup populations elsewhere.
- Data in notebooks from the early 20th century show that sockeye salmon populations have crashed even more than usually thought.
- New dragonfly and damselfly species continue to be found in Sri Lanka, but many are threatened by increasing water pollution.
