Tracking Fish Lifetime Exposure to Mercury Using Eye Lenses.

Mercury (Hg) uptake in fish is affected by diet, growth, and environmental factors such as primary productivity or oxygen regimes. Traditionally, fish Hg exposure is assessed using muscle tissue or whole fish, reflecting both loss and uptake processes that result in Hg bioaccumulation over entire lifetimes. Tracking changes in Hg exposure of an individual fish chronologically throughout its lifetime can provide novel insights into the processes that affect Hg bioaccumulation.

Functional traits reveal the dominant drivers of long-term community change across a North American Great Lake.

Ecosystems worldwide have been impacted by multiple anthropogenic stressors, yet efforts to understand and manage these impacts have been hindered by difficulties in disentangling relative stressor effects. Theoretically, the actions of individual stressors can be delineated based on associated changes in functional traits and these relationships should be generalizable across communities comprised of different species. Thus, combining trait perspectives with community composition data could help to identify the relative influence of different stressors.

Improving communication and documentation concerning preliminary and final radiology reports.

The communication and documentation of radiology preliminary and final interpretations for the identification of discrepancies failed to evolve with radiology's transition away from film. Processes should facilitate documentation and distribution of preliminary findings to multiple practitioners in real time and should provide timely communication and documentation of additional findings. The evolution of the electronic medical record and digital radiology images provided an opportunity to establish effective, safe, and efficient methods of communication and documentation.
