Long-term population sampling for the Preble\u2019s meadow jumping mouse (PMJM) has allowed Rob Schorr to estimate population change (\u03bb) for the population along Monument Creek at the U.S. Air Force Academy (Academy).  Using mark-recapture techniques and a novel population model that allows estimation of survival and recruitment, Schorr estimated changes in PMJM \u03bb from 2000-2006.  Although \u03bb varied annually, the 7-year mean showed a declining population, and \u03bb was less impacted by changes in PMJM survival than by changes in PMJM recruitment.<\/p>\n\n\n\n\n

\nRecruitment can be influenced by immigration or reproduction.  Given the loss of habitat along eastern tributaries of Monument Creek, there are limited opportunities for increasing immigration from these tributaries and this may be a driving force during this time.  However, Schorr warns that this may be a temporary decline that will be compensated by increased reproduction or immigration from western tributaries that are on the Academy.<\/p>\n\n\n\n\n
