Protected fish spawning aggregations as self-replenishing reservoirs for regional recovery.

Dispersal of eggs and larvae from spawning sites is critical to the population dynamics and conservation of marine fishes. For overfished species like critically endangered Nassau grouper (), recovery depends on the fate of eggs spawned at the few remaining aggregation sites. Biophysical models can predict larval dispersal, yet these rely on assumed values of key parameters, such as diffusion and mortality rates, which have historically been difficult or impossible to estimate.

Recovery of critically endangered Nassau grouper () in the Cayman Islands following targeted conservation actions.

Many large-bodied marine fishes that form spawning aggregations, such as the Nassau grouper (), have suffered regional overfishing due to exploitation during spawning. In response, marine resource managers in many locations have established marine protected areas or seasonal closures to recover these overfished stocks. The challenge in assessing management effectiveness lies largely in the development of accurate estimates to track stock size through time.

Association Between Nonmodifiable Demographic Factors and Patient Satisfaction Scores in Spine Surgery Clinics.

The Press Ganey survey is the most widely used instrument for measuring patient satisfaction. Understanding the factors that influence these surveys may permit better use of survey results and may direct interventions to increase patient satisfaction. Press Ganey Clinician and Group Consumer Assessment of Healthcare Providers and Systems surveys administered to ambulatory spine surgery clinic patients within a large tertiary care network from May 2016 to September 2017 were retrospectively reviewed.
