Nutrient compensatory foraging in a free-living social insect.

The geometric framework model predicts that animal foraging decisions are influenced by their dietary history, with animals targeting a combination of essential nutrients through compensatory foraging. We provide experimental confirmation of nutrient-specific compensatory foraging in a natural, free-living population of social insects by supplementing their diet with sources of protein- or carbohydrate-rich food. Colonies of the ant Iridomyrmex suchieri were provided with feeders containing food rich in either carbohydrate or protein for 6 days, and were then provided with a feeder containing the same or different diet. The patterns of recruitment were consistent with the geometric framework: while feeders with a carbohydrate diet typically attracted more workers than did feeders with protein diet, the difference in recruitment between the two nutrients was smaller if the colonies had had prior access to carbohydrate than protein. Further, fewer ants visited feeders if the colony had had prior access to protein than to carbohydrates, suggesting that the larvae play a role in worker foraging behaviour.

Clinical decision support to avoid adverse drug events with anticoagulants.

Unintentional duplication or timing of anticoagulant orders leaves patients at high risk for serious adverse events. Alerts at the point of electronic order entry have the potential to mitigate this risk; however poor specificity with a high frequency of interruptions may decrease the ability of a clinician to recognize specific hazards. This poster will depict custom clinical decision support designed to prevent specific misadventures with this high risk class of medications.
