A team of researchers has found a key to improving long-term survival of the endangered Florida Scrub-Jay. "Clustered habitat networks" can maintain genetic diversity for a species at risk of extinction, and offer a model for similar conservation efforts.

Coral-eating sea star invaders turn out to be locals

Researchers have disproven the secondary outbreak hypothesis in the Central Pacific. One of the greatest biological threats to tropical coral reefs can be a population outbreak of crown-of-thorns (COT) sea stars (Acanthaster planci). Outbreaks can consume live corals over large areas, a change that can promote algal growth and alter reef fish populations.
