Abstract: In a natural resource management setting, monitoring is crucial component of an informed process for making decisions, and design should be driven by the decision context associated uncertainties. Monitoring itself can play ≥3 roles. First, it important state‐dependent decision‐making, as when managers need to know system state before deciding on appropriate course action during ensuing cycle. Second, critical evaluating effectiveness actions relative objectives. Third, in adaptive...
Abstract Climate change and its associated uncertainties are of concern to natural resource managers. Although aspects climate may be novel (e.g., system nonstationarity), managers have long dealt with developed corresponding approaches decision‐making. Adaptive management is an application structured decision‐making for recurrent decision problems uncertainty, focusing on objectives, the reduction uncertainty over time. We identified 4 types that characterize in management. examined ways...

Understanding how events during one period of the annual cycle carry over to affect survival and other fitness components in periods is essential understanding migratory bird demography conservation needs. Previous research has suggested that western Atlantic red knot (Calidris canutus rufa) populations are greatly affected by horseshoe crab (Limulus polyphemus) egg availability at Delaware Bay stopover sites their spring northward migration. We present a mass-based multistate,...

Conservation of migratory birds throughout the full annual cycle requires a comprehensive understanding abundance and distribution in interconnected breeding, migration, wintering habitats. The Mountain Plover (<em>Anarhynchus montanus</em>) is rare endemic breeder Rocky Great Plains regions that migrates to grounds southwestern USA northern Mexico. Information regarding its distribution, particularly Texas, limited. This study provides first population estimate for Plovers Texas examines...
The nonbreeding distribution of Western Sandpipers (Calidris mauri) was documented using 19 data sets from 13 sites along the Pacific and Atlantic coasts Americas. showed latitudinal segregation with regard to sex age. Females wintered farther south than males. A “U” shaped pattern found respect age, juveniles occurring at higher proportions both northern southern ends range. Distribution sexes might be affected by differences in bill length a trend depth prey. For age class distribution,...

Abstract Conserving migratory birds is made especially difficult because of movement among spatially disparate locations across the annual cycle. In light challenges presented by scale and ecology birds, successful conservation requires integrating objectives, management, monitoring scales, from local management units to ecoregional flyway administrative boundaries. We present an integrated approach using a explicit energetic‐based mechanistic bird migration model useful decision‐making...
Ecological restoration has traditionally been evaluated by monitoring the recovery of ecological conditions, such as species abundance and diversity, physical form, water quality; social benefits is uncommon. Current frameworks do not track who from or how much. We investigate could be monitored to provide indications improvement in terms conditions. suggestions for measuring several categories indicators, including access, beneficiaries, quality benefit, using information compiled natural...
Semipalmated Sandpipers (Calidris pusilla) stop at staging areas during migration to replenish fat reserves that fuel long distance flights. We hypothesize if sandpipers are minimizing time spent en route between wintering and breeding grounds, a negative correlation should exist content upon arrival area length of stay. examined the relationship these two variables spring in coastal South Carolina using simple multiple regression models. Length stay was independent estimated capture after...
