A new study published in The American Naturalist links grazing halo patterns in coral reefs, as well as those in other patchy habitats, to the spatial patterns of the shelter habitat itself. The researchers found that grazing halos are distinct when the coral is clustered but merge into each other when the coral is dispersed. According to the lead author, "...gaining a better understanding of how halo patterns reflect reef community dynamics may be useful in reef conservation efforts."

University of Utah hydrologists show most streamflow out of the West’s mountains is old snowmelt on a multi-year underground journey. New study finds that spring runoff is on average 5 years old.
