File Information The FrogAbnormalities.csv data set includes information on each of the 9,011 individual amphibians surveyed for this effort. Information on data in each column follows. Column Information The Frog.csv data set includes the following column headings: COLLECTION_ID --- The collection ID always follows the same format, ("site_id”-”species ”-“date" in the format, “MMDDYY”). All amphibians sampled for this project were Lithobates sylvaticus (formerly Rana sylvatica or RASY), based on the following reference, Crother B (2012) Scientific and standard English names of amphibians and reptiles of North America north of Mexico. Saint Louis, MO: Society for the Study of Amphibians and Reptiles. FROG_ID---This combines with the collection_id field to create a unique identifier for each individual amphibian sampled. SITE---The identifier for each wetland in which an animal was sampled. This field provides a join field to the site.csv file. YEAR---The calendar year in which the animal was sampled. GOSNER_STAGE---The developmental stage of the animal, based on the following reference, Gosner KL (1960) A simplified table for staging anuran embryos and larvae with notes on identification. Herpetologica 16: 183-190. All animals were “metamorphs”, between stages 42 and 46. “NULL” codes for missing data. SVL---The length of the animal from snout (tip of nose) to vent (cloaca), measured in mm. In animals with tails, SVL does not include tail length. “NULL” codes for missing data. TAIL_LENGTH--- The length of the animal’s tail from the vent (cloaca) to the tail tip, measured in mm. DATE---The date on which the animals were sampled. For more information on the following categories, please refer to the “Abnormality Classification SOP” document, which is included with this data submission. Each of these columns includes a binomial (0 or 1) response variable coding for whether the animal had an abnormality of each of these specific types (“1”) or not (“0”). The first 10 categories are data summarized from the SOP columns as follows: ABNORMAL---Includes all categories of abnormalities in the SOP. These are the final columns of the spreadsheet, which are described in detail in the “Abnormality Classification SOP” document also included with this data submission - Table 1 of this SOP document links the names in the databases to the descriptive categories in the SOP. It was possible to have more than one type of abnormality. In this case, it would receive a count for each SOP level abnormality it had, but all the summary categories above this in this document count abnormal animals, not individual abnormalities. For example, and animal with a shrunken limb and an abnormal eye would have a "1" in each of the SOP level columns, however, it would only be counted once in the "skeletal_plus_eye" category. EYE_AB---Includes the following categories of abnormalities: abnormal_iris_coloration abnormal_eye_size_shape_iris_or_pupil anopthalmia eye_abnormality_other BLEEDING_INJ---Includes the following categories of abnormalities: amelia_full_remove_bloody appendage_dislocated_broken_dangle brachydactyly_bone_protruding_or_blood_at_stump ectrodactyly_bone_protruding_or_blood_at_stump ectromelia_bone_protruding_or_blood_at_stump digits_curled_smashed_with_blood skeletal_injury_other bifurcated_tail pooled_blood intestines_protruding trauma_or_cut SKEL_AB---Includes the following categories of abnormalities: brachydactyly ectrodactyly ectromelia kinked_tail non_flexible_limb one_limb_thinner skeletal_abnormality_other amelia_full_remove_bloody appendage_dislocated_broken_dangle brachydactyly_bone_protruding_or_blood_at_stump ectrodactyly_bone_protruding_or_blood_at_stump ectromelia_bone_protruding_or_blood_at_stump digits_curled_smashed_with_blood skeletal_injury_other amelia anteversion brachynathia clinodactyly cutanuous_fusion hemimelia microcephaly micromelia polydactyly polymelia polyphalangy scoliosis syndactyly taumelia skeletal_malformation_other SURF_AB---Includes the following categories of abnormalities: bifurcated_tail pooled_blood edema cysts intestines_protruding missing_typanum pigment_anomaly trauma_or_cut surface_other Perkensus---Animals with a 1 in this category were diagnosed in the field with visual signs of infection by an undescribed protozoan pathogen, similar to Perkensus marinus. The taxonomy of this organism has not been done and the pathology has not been verified by a lab in most cases. FROG_COMMENTS---These are descriptions of the abnormalities by those who examined the animals in the field. Notes about the frogs were taken by field crews during frog assessment. Statements are anecdotal observations by field crew members of variable levels of expertise and training. The veracity of these statements has not been verified. These statements represent the opinions and observations of individual workers and do not necessarily represent the views of the U.S. Fish and Wildlife Service. Pictures are not available.
