Live performance to 96 d was compared for 1,584 turkey toms reared on diets containing four levels of whole barley and two levels of insoluble grit (0 or 9 g/bird per wk). Nutrient specifications for all diets were similar. The six dietary treatments were 1) 0% whole barley plus grit, 2) Treatment 1 minus grit, 3) grit plus 5% whole barley at 0 d increasing to 35% by 19 d, 4) grit plus 5% whole...

In this research, we investigate how grittier individuals might incur some costs by persisting when they could move on. Grittier participants were found to be less willing to give up when failing even though they were likely to incur a cost for their persistence. First, grittier participants are more willing to risk failing to complete a task by persisting on individual items. Second, when they...

The Black Brant Branta bernicla nigricans is a seagrass-obligate goose, strongly tied to the estuaries of the Pacific Flyway coast of North America. Black Brant are unique in that they remain reliant on their traditional food resource, in contrast to other Brent Goose populations that now readily switch to feed on agricultural land during migration and in winter. While Black Brant use of coasta...

—In herbivorous birds the processing rate of food is constrained by gizzard capacity. To enhance digestive processes, many species ingest grit to grind the food. Grit ingestion, however, may further limit the capacity of the gizzard. Graylag Geese (Anser anser) wintering in SW Spain fed mainly on Alkali Bulrush (Scirpus maritimus) tubers, showing a preference for small tubers. This preference m...

The objective of this short-term longitudinal study was to examine individual versus classroom peer effects of grit on later individual literacy achievement in elementary school.
