Low-lying areas of tropical Pacific islands

Sea level is rising faster than projected in the western Pacific, so understanding how wave-driven coastal flooding will affect inhabited, low-lying islands—most notably, the familiar ring-shaped atolls—as well as the low-elevation areas of high islands in the Pacific Ocean, is critical for decision-makers in protecting infrastructure or relocating resources and people.

    Developing optimal post-fire restoration strategies to build ecosystem resilience - Stephanie Yelenik

    Grass-fire cycles are a problem globally, contributing to expanding exotic grasslands, decreased forest area, and increased fire frequency/size worldwide. Thus, to create resilience to fire in these landscapes, we need to better understand grass-fire interactions and how to restore communities that can resist grass invasion.
