Humpback Chub (Gila cypha) capture history data (2009-2017), and code for mark-recapture analysis and stochastic matrix projections, Colorado River and Little Colorado River, Arizona

These data represent capture histories for humpback chub (Gila cypha) that spawn in the Little Colorado River (LCR) from 2009-2017. Capture histories pertain to size class (<150mm total length [TL], 150-199mm TL, 200-249mm TL, and >250mm TL) and spatial location (the juvenile chub monitoring [JCM] reach in the Colorado River [63.4-65.0 river miles downstream of Lees Ferry], lower LCR [0-13.56 km upstream of Colorado River confluence], and upper LCR [13.57-17.9 km upstream of Colorado River confluence]).

Bartram's Stonecrop (Graptopetalum bartramii) survey data from southern Arizona, 2020-2021

These data were compiled for the U.S. Fish and Wildlife Service to assist them with updating the current status of the species Bartram's Stonecrop (Graptopetalum bartramii). Objective(s) of our study were to survey selected sites within the of Bartram's Stonecrop for future management and protection. These data represent summary population counts at selected known sites for the Federally listed Threatened plant species, Bartram's Stonecrop (Graptopetalum bartramii). These data were collected in the southern Arizona portion of the species' range, stratified across Sky Island Mountain ranges from the Rincon Mountains south to the Atascosa Highlands, just north of the Mexican border. Sites were selected to represent...
