Barred tiger salamander (paedomorph)
Barred Tiger Salamander Paedomorph, Cottonwood Lake Study Area, North Dakota. Some barred tiger salamanders never metamorphose and keep their larval features (e.g., gills, finlike tail) their whole lives as reproductively mature adults known as paedomorphs, which can grow to be 14 inches in length.

Grass carp larvae
These images show grass carp larvae from the Maumee River. Characteristics of larval grass carp include overall length (left), skeletal muscle development (center) and presence of an eye spot that lacks pigmentation (right; pigment starting to develop on lower eye).

Managing Fire on the US Mexico Borderlands
RAMPS met with DOI Office of Wildland Fire, US Customs and Border Patrol, and US Fish & Wildlife Service staff at Buenos Aires National Wildlife Refuge in southern AZ last November. The group is developing tools to reduce wildfire risk, conserve wildlife habitat and natural resources, and increase safety and security of border operations.

Arid grassland
Arid grasslands in the U.S. Mexico border are fire adapted and used by diverse groups. Science from the Southwest Biological Science Center and the Restoration Assessment and Monitoring Program for the Southwest (RAMPS) is helping these groups find common ground to manage this dynamic landscape.
