Edge effects on the regeneration of forest fragments in south Brazil
... Forested environments are being cleared all over the world. From 1981 to 1990, the loss of tropical forests was estimated at 154 million ha. As a result of that, the interface between forest and open environment has increased greatly. General patterns of species distribution and dynamics in these fo ...

Caribbean acroporid coral hybrids are viable across life history stages

Fused staghorn coral, A. prolifera, is an F1 hybrid with an intermediate morphology to the parental species. The hyb ...
