Choice and context: testing a simple short-term choice rule

Article Abstract:

Psychological studies of animal choice show that the immediate consequences of choice strongly influence preference whereas evolutionary models emphasize the longer-term fitness consequences of choice and two experiments that address this conflict is addressed. An alternative choice situation based on patch-leaving decisions is developed and compared to the binary choice, or self-control, situation typically used in psychological studies.

Genotypic differences in space use and movement patterns in Drosophila melanogaster

Article Abstract:

Five Drosophila melangaster recurrent F1s were used to investigate genotypic differences in space use and movement patterns, focusing on the behavior of teneral females and individually marked young adults that were allowed free access to large, structurally complex environments. Teneral females from the five F1s differed in their propensity to hide after emergence and in the height at which they perched above the substrate.
