Data from: Time-integrated habitat availability is a resource attribute that informs patterns of use in intertidal areas

Leonardo Calle, Lauri Green, Allan Strong & Dale E. Gawlik
In dynamic environments, resource availability may change by several orders of magnitude, over hours to months, but the duration of resource availability is not often included as a characteristic attribute of resources even though temporal resource dynamics might limit patterns of use. In our study of wading birds foraging in intertidal areas, tides cause large changes in the areal extent of shallow-water foraging habitat (i.e., the resource), but tides also constrain the duration of availability,...

Data from: Linkage and trade-off in trophic morphology and behavioral performance of birds

Clay E. Corbin, Lauren K. Lowenberger & Brandan L. Gray
1. Bill closing behaviour involves a complex suite of tissue types, kinematics, morphological states and muscle architectural arrangements that has been under the scrutiny of natural selection for millions of years. Hence, an evolutionary shift to specialize in closing force may come at a cost to closing velocity and vice versa. 2. Using field measurements on behavioural performance and morphological data from museum specimens, we tested predictions of the force–velocity trade-off hypothesis in 18 species...
