Data from: Using artificial intelligence classification of videos to examine the environmental, evolutionary and physiological constraints on provisioning behavior

Heather M. Williams & Robert L. DeLeon
The use of artificial intelligence (AI) technologies can revolutionize how we approach data collection and analysis in behavioral ecology. One such example is in provisioning behavior. Parents of altricial species are selected to provide parental care (such as food provisioning) for their offspring, but there is substantial variation in the level of this care. Provisioning rate may be determined environmentally, by the physiological ability of parents and needs of nestlings, or by evolutionary incentives. We...

Coregonus spp. opsin amplicon sequence alignments

Katherine Eaton & Trevor Krabbenhoft
Local adaptation can drive diversification of closely related species across environmental gradients and promote convergence of distantly related taxa that experience similar conditions. We examined a potential case of adaptation to novel visual environments in a species flock (Great Lakes salmonids, genus Coregonus) using a new amplicon genotyping protocol on the Oxford Nanopore Flongle. Five visual opsin genes were sequenced for individuals of C. artedi, C. hoyi, C. kiyi, and C. zenithicus. Comparisons revealed species-specific...

Landmarks and 3D scan data of Macaca fascicularis

Hyunwoo Jung, Evan Simons & Noreen Von Cramon-Taubadel
Objectives: Magnitudes of morphological integration may constrain or facilitate craniofacial shape variation. The aim of this study was to analyze how the magnitude of integration in the skull of Macaca fascicularis changes throughout ontogeny in relation to developmental and/or functional modules. Materials and Methods: Geometric morphometric methods were used to analyze the magnitude of integration in the macaque cranium and mandible in 80 juvenile and 40 adult M. fascicularis specimens. Integration scores in skull modules...

Support for a relationship between demography and modeled habitat suitability is scale dependent for the Purple Martin, Progne subis

Heather Williams, Joe Siegrist & Adam Wilson
1. Species distribution models (SDMs) estimate habitat suitability for species in geographic space. They are extensively used in conservation under the assumption that there is a positive relationship between habitat suitability and species success and stability. 2. Given the difficulties in obtaining demographic data across a species’ range, this assumption is rarely tested. Here we provide a range-wide test of this relationship for the eastern subspecies of purple martin (Progne subis subis). 3. We build...
