Selectivity2023.csv

Dataset of field experiments on hummingbirds' selectivity and hummingbirds morphology used in Guevara et al., 2023 <strong>Hummingbird community structure and nectar resources modulate the response of interspecific competition to forest conversion</strong> (submitted to Oecologia). <br> Selectivity approximates the competitive ability of hummingbirds to access optimal nectar resources (see methods Guevara et al., 2023). <br> Metadata of <strong>Selectivity2023 file</strong> <strong>site</strong>: name of the reserve or farm were the experiment was done <strong>habitat</strong>: type of habitat <strong>forest conversion</strong>: dummy variable indicating whether forest conversion have occurred (0 = forest, 1 = converted) <strong>hummingbird:</strong> hummingbird species <strong>activity</strong>: measure of hummingbird species' activity at experimental feeders (number of visits per species divided over the total number of visits of all hummingbirds) <strong>trial</strong>: trial number <strong>day: </strong>date of the experiment <strong>day2</strong>: day number used in analyses <strong>hour:</strong> hour during the day at which the observation was done <strong>time10:</strong> time in seconds spent feeding at the 10% percent feeder <strong>time30</strong>: time in seconds spent feeding at the 30% percent feeder <strong>timeT</strong>: total time spent at both feeders <strong>selectivity</strong>: proportion of time spent at the optimal resource in relation to the total <strong>resources.all: </strong>number of open flowers around 100m nearby the experimental trials <strong>morph.distance: </strong>morphological distance among competing humminbgbirds (see methods Guevara et al., 2023). <strong>weighted.distance</strong>: morphological distance weighted by activity (see methods Guevara et al., 2023). <br> <br> <br> <br>
