Listening to male song induces female field crickets to differentially allocate reproductive resources

Orientation to calling song by female crickets, Scapsipedus marginatus (Gryllidae).

Females allocate differentially to offspring size and number in response to male effects on female and offspring fitness.

Female investment in offspring size and number has been observed to vary with the phenotype of their mate across diverse taxa. Recent theory motivated by these intriguing empirical patterns predicted both positive (differential allocation) and negative (reproductive compensation) effects of mating with a preferred male on female investment. These predictions, however, focused on total reproduct...

How to Allocate Resources For Features Acquisition?

We study classification problems where features are corrupted by noise and where the magnitude of the noise in each feature is influenced by the resources allocated to its acquisition. This is the case, for example, when multiple sensors share a common resource (power, bandwidth, attention, etc.). We develop a method for computing the optimal resource allocation for a variety of scenarios and d...

Using Performance Prediction to Allocate Grid Resources

Large-scale applications often require computational grids to obtain the needed compute power for execution. Generally, users are given access to a collection of resources that can be used for execution. The collection of resources can be dynamic, and the users must decide which collection of heterogeneous and distributed resources to use. However, many users often do not have knowledge of all ...

Female Field Crickets Incur Increased Parasitism Risk When Near Preferred Song

Female animals often prefer males with conspicuous traits because these males provide direct or indirect benefits. Conspicuous male traits, however, can attract predators. This not only increases the risk of predation for conspicuous males but also for the females that prefer them. In the variable field cricket, Gryllus lineaticeps, males that produce preferred song types provide females with g...
