Amac Morphology Raw Data

This dataset was used for the analyses reported in "Trait variation in patchy landscapes: morphology of spotted salamanders (Ambystoma maculatum) varies more within ponds than between ponds". Data were collected from photo images in 2016 by E. Green and D. Daversa. The data reports morphological traits of spotted salamanders collected in Eastern Missouri. Pond characteristics are also included in the data set. Specifically, the dataframe contains the following columns: ID: Unique identifier for individualsdate: date of capture yearday: day of the year that individual was capturedspecies: the Genus and species of the individual (all are A. maculatum)side_image: A unique ID for photo image taken of the side of the individual (we also took ventral photos that were not used in the analysis)stage: larval developmental stage as described by Harrison (1969). See main text for citation. pond: name of the pond where the individual was capturesite: name of the conservation property where the pond of capture was located dipnets: number of dipnets made at the pond where individual was captureddensity: estimated salamander density in ponds according to dipnet surveysdensity_key: a categorical variable describing the density of salamanders at the pond, relative to other survey pondsspecies_richness: Number of amphibian species captured during dipnet surveypredator_sum: the total number of predator individuals found at the pondpredator_richness: The number of predator species found at the pondpredator_density: estimated number of predators in the pond of capturepred_key: A categorical variable describing the density of predators in the pond of capture, relative to other survey pondsorigin: The age of the pond of capture (new vs. old)head_length: linear length of head (mm)head_height: Linear height of head (mm)tail_height: linear height of tail (mm)total length: linear body length, including head and tail (mm)mass: the weight of the individual (g)whole_shape: morphometric shape of individual, including all body segmentsbody_shape: morphometric shape of the body, excluding head and tailtail_shape: morphometric shape of the tailhead_shape: morphometric shape of the head
