Title Observations of C. Turbinata foraging behavior in the field
Downloaded 1 time
Description These data describe 10 days of continuous observations of the behavioral responses ("Event"-- attack or rest) of 9 individual female Cyclosa turbinata ("ID") to prey items hitting the web at different times of day ("TimeofDay.h").

Title Metabolic Calculations for C. turbinata
Downloaded 1 time
Description Metabolic calculations used to estimate the proportion of prey energy consumed per time step in the dynamic model. Includes estimates of metabolic rate for C. turbinata in microliters of oxygen per hour (Greenstone & Bennett 1980) and conversion factors from Gnaiger 1983 and Riechert 1991.

Title Collated Predator and Prey Abundances for C. turbinata
Downloaded 1 time
Description These data describe daily patterns in the abundances of potential predators (wasps) and prey (arthropods <1.5 cm in length) of C. turbinata in the field. The data include pooled estimates of encounter rates per 3 hour interval collated from Moore et al. 2016 ("PreyTrapped", "PredatorsTrapped"), and subsequent calculations to yield encounter rates per day ("Prey.per.Day", "Pred.per.Day") and per time step ("Prey.per.t", "Pred.per.t"), as well as encounter probabilities per time step ("ProbEncPrey.per.t", "ProbEncPred.per.t").

Title R Code for Dynamic Model of Sit-and-Wait Foragers
Downloaded 2 times
Description This file contains R code for the dynamic model used to determine whether temporal variation in predation risk favors daily patterns of foraging behavior in a sit-and-wait predator. This file was created using R v3.4.1. Additional versions of the model code (i.e., those used to plot effects of various model parameters) are available by request.

Title R Code for Dynamic Model of Searching Foragers
Downloaded 3 times
Description This file contains R code for an extension of our dynamic model that considers scenarios in which foragers must actively search for prey to attack. The R code was produced in R v.3.4.1.
