Data from: Selection for mechanical advantage underlies multiple cranial optima in new world leaf-nosed bats

Elizabeth R. Dumont, Krishna Samadevam, Ian R. Grosse, Omar M. Warsi, Brandon Baird, Liliana M. Davalos & Ian Grosse
Selection for divergent performance optima has been proposed as a central mechanism underlying adaptive radiation. Uncovering multiple optima requires identifying forms associated with different adaptive zones and linking those forms to performance. However, testing and modeling the performance of complex morphologies like the cranium is challenging. We introduce a three-dimensional finite element (FE) model of the cranium that can be morphed into different shapes by varying simple parameters to investigate the relationship between two engineering-based...

Data from: Phylogenetic, ecological, and allometric correlates of cranial shape in Malagasy lemuriforms

Karen L. Baab, Jonathan M. G. Perry, F. James Rohlf & William L. Jungers
Adaptive radiations provide important insights into many aspects of evolution, including the relationship between ecology and morphological diversification as well as between ecology and speciation. Many such radiations include divergence along a dietary axis, although other ecological variables may also drive diversification, including differences in diel activity patterns. This study examines the role of two key ecological variables, diet and activity patterns, in shaping the radiation of a diverse clade of primates, the Malagasy lemurs....

Data from: Sustained costs of growth and the trajectory of recovery

Kestrel O. Perez & Stephan B. Munch
1. Large body size is associated with many fitness advantages. Despite this, most species do not grow at their physiological maximum, suggesting costs to rapid growth. There are now many empirical examples of trade-offs with growth. 2. Despite the ubiquity of physiological delays, few studies have evaluated the duration over which growth costs occur. To address this question, we measured swimming ability in growth-manipulated Atlantic silversides (Menidia mendia). Fish were manipulated to grow at their...

Data from: MotionMeerkat: integrating motion video detection and ecological monitoring

Ben G. Weinstein
1. Human observation is expensive and limits the breadth of data collection. For this reason, remotely placed video cameras are increasingly used to monitor animals. One drawback of field-based video recordings is extensive review time. Computer vision can mitigate this cost and enhance data collection by extracting biological information from images with minimal time investment. 2. MotionMeerkat is a new standalone program that identifies motion events from a video stream. After running a video, the...
