The responses of pikas and marmots to weather and snowpack dynamics have been species-specific.   

In 2018, USGS and partners completed an incredible feat against a harmful aquatic invasive species when over 240,000 pounds of invasive Silver Carp and Bighead Carp were removed from Creve Coeur Lake in Maryland Heights, Missouri.

Siyeh Glacier (upper – 2015 satellite photo,  lower - 2005 aerial photo). The glacier margin is more clearly identified in the 2015 image  because seasonal snow is persisting on the ice and rock debris atop the ice can be more clearly seen than in the heavily shaded 2005 image.
