Ecosystem resilience to invasion and drought: Insights after 24 years in a rare never‐grazed grasslandNARA Subscribed
Understanding the resilience of ecosystems globally is hampered by the complex and interacting drivers of change characteristic of the Anthropocene. This is true for drylands of the western US, where widespread alteration of disturbance regimes and spread of invasive non‐native species occurred with westward expansion during the 1800s, including the introduction of domestic livestock and spread of Bromus tectorum , an invasive...
Droughting a megadrought: Ecological consequences of a decade of experimental drought atop aridification on the Colorado PlateauNARA Subscribed
Global dryland vegetation communities will likely change as ongoing drought conditions shift regional climates towards a more arid future. Additional aridification of drylands can impact plant and ground cover, biogeochemical cycles, and plant–soil feedbacks, yet how and when these crucial ecosystem components will respond to drought intensification requires further investigation. Using a long‐term precipitation reduction expe...
A hidden Markov model for estimating age‐specific survival when age and size are uncertainNARA Subscribed
Estimates of age‐specific survival probabilities are needed for age‐structured population models and to inform conservation decisions. However, determining the age of individuals in wildlife populations is often problematic. We present a hidden Markov model for estimating age‐specific survival from capture–recapture or capture–recapture–recovery data when age is unknown and indicators of age, such as size and growth layer coun...
