Vocalizations of the squirrel family

The dataset Squirrel_Calls is a collection of vocal records (defined as
primary literature that numerically describes the vocalization of at least
1 squirrel species) where each row corresponds to a single call type of
one species. The details of the row include a summary of the literature
metadata, categorical descriptions of the call and the caller as well as
numerical values of the call frequencies. The dataset
Squirrel_Ecological_Traits is a corresponding set of ecological traits for
all the species listed in the Squirrel_Calls dataset. The traits listed
(mass, time partitioning, gliding capabilities, habitat, and sociality)
reflect hypotheses and predictions explored in the associated article. At
the end of this document, there is a complete list of the literature
references used to assemble these datasets. Squirrel_Script is the R
script used to produce the statistics and models used in the corresponding
paper. Squirrel_Tree is a nexus file compiling the data of 1000 trees
downloaded from VertLife.org which were subsetted from their published
mammalian supertree. The nexus file was used in the R script.
