While the susceptibility of endangered akepa honeycreepers to avian malaria is unknown, it is likely very high given their current restriction to the highest elevation forests on the island of Hawaii.

During the past decade populations of this honeycreeper have begun to rebound at lower elevations on most of the main Hawaiian Islands, in spite of high prevalence of infection with avian malaria. Natural selection for resistance to avian malaria is the leading explanation for this rebound and recent genetic studies indicate that these populations are genetically distinct

Routine maintenance on a ground-water monitoring well,
Perry Park, Brunswick, Glynn County, Georgia. At one time this well was used by the City of Brunswick for drinking water. Saltwater intrusion forced the city to abandon the well, so the USGS started monitoring it for water levels and specific conductance.

A coyote walking in dry creek bed of streamside scrub vegetation dominated by the native plant, mule fat (Baccharis salidifolia), about 20 days before the fire. In their wildlife research, USGS scientists position camera traps along trails and dry creek beds, places that are likely to be travel routes for carnivores. From this particular location in Borrego Wash, the
