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 from their higher elevation counterparts.]]> http://gallery.usgs.gov/photos/05_22_2009_h41Og66Fea_05_22_2009_1 <![CDATA[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.]]> http://gallery.usgs.gov/photos/05_22_2009_h41Og66Fea_05_22_2009_2 <![CDATA[While still common at higher elevations, iiwi are extremely susceptible to avian malaria.

"Likely secure populations" indicates areas where sage-grouse are present and currently stable. "Currently extirpated" indicates areas where sage-grouse are now locally extinct, as the model predicted. "Potential recolonization" indicates areas where populations are known to be locally extinct, but based on the model, landscape conditions are most similar to areas where sage-grouse currently persist. "At-risk populations" predicts absence where populations are known to occur. These habitats are most similar to areas where sage-grouse have already disappeared; therefore, existing populations are likely at risk of local extinction.]]> http://gallery.usgs.gov/photos/160
