READ ME: Precision of cementum annuli method for aging male white-tailed deer Citation ***when available*** Author Information Daniel M. Adams, Julie A. Blanchong Department of Natural Resource Ecology and Management, Iowa State University Corresponding author: Daniel Adams, dadams6218@gmail.com AdamsBlanchong_TeethAges.csv Content- .csv spreadsheet of white-tailed deer tooth-replacement-and-wear and incisor cementum annuli age estimates Columns and explanation- Deer_ID- unique identification of each deer Harvest_Date- date deer was harvested; UNK = unknown Year- year deer was harvested TRW_Age- tooth-replacement-and-wear (TRW) age estimate (in year classes) for the deer; ages were estimated using three age classes: 1.5, 2.5, 3.5+ Conf_Level- confidence level of the person that aged the deer using TRW in their age estimate; confidence levels were recorded as high (H), medium (M), or low (L) CA_Age1- cementum annuli (CA) age estimate (in years) for the deer's first incisor Matson_CC1- certainty code applied to CA_Age1 estimate by the laboratory that aged the deer; ranges from greatest ("A") to least certainty ("C") CA_AR1- age range (in years) provided by the laboratory that aged the deer that the deer's age probably falls into if CA_Age1 estimate is incorrect (if applicable) Mat_Batch1- batch of teeth aged by the laboratory that aged the deer in which the CA_Age1 estimate was determined CA_Age2- cementum annuli age estimate (in years) for the deer's second incisor (if applicable) Matson_CC2- certainty code applied by the laboratory that aged the deer to CA_Age2 estimate; ranges from greatest ("A") to least certainty ("C") CA_AR2- age range (in years) provided by the laboratory that aged the deer that the deer's age probably falls into if CA_Age2 estimate is incorrect (if applicable) Mat_Batch2- batch of teeth aged by the laboratory that aged the deer in which the CA_Age2 estimate was determined Batch- batch code assigned to paired incisors (first and second incisors from a deer) based on the batches (1, 2 or 3) in which the two incisors were aged by the laboratory that aged the deer using cementum annuli; batch code for pairs: First & second batch (1-2) = 'A', 2-3 = 'B', 1-3 = 'C', 3-3 = 'D' AdamsBlanchong_DupAges.csv Content- .csv spreadsheet of paired white-tailed deer cementum annuli age estimates to be read into Program R for analysis Columns and explanation- DeerID- unique identification of each deer AgeA- cementum annuli age estimate for the first incisor provided by the laboratory that aged the deer AgeB- cementum annuli age estimate for the second incisor provided by the laboratory that aged the deer Abs- absolute value of the difference in age estimates between AgeA and AgeB Diss- binary indicating if AgeA and AgeB estimates disagreed; "0" indicates no disagreement between the age estimates, "1" indicates disagreement Diss2- binary indicating if AgeA and AgeB estimates agreed; "0" indicates no agreement between the age estimates, "1" indicates agreement CccodeA- binary indicating the certainty code of the AgeA estimate provided by the laboratory that aged the deer; "0" indicates 'A' certainty code, "1" indicates either 'B' or 'C' certainty code CccodeB- binary indicating the certainty code of the AgeB estimate provided by the laboratory that aged the deer; "0" indicates 'A' certainty code, "1" indicates either 'B' or 'C' certainty code Certainty- binary indicating certainty of both the AgeA and AgeB estimates; "0" indicates that both age estimates had an 'A' certainty code (high certainty), "1" indicates that at least one of the age estimates did not have an 'A' certainty code (low certainty) Batch- batch code assigned to paired incisors (first and second incisors) based on the batches in which the incisors were aged by the laboratory that aged the deer when four batches were compared; batch code for pairs (four): First & second batch (1-2) = 'A', 2-3 = 'B', 1-3 = 'C', 3-3 = 'D' Batch2- batch code assigned to paired incisors (first and second incisors) based on the batches in which the incisors were aged by the laboratory that aged the deer when three batches were compared; batch code for pairs (three): 1-2 & 1-3 = 'A', 2-3 = 'B', 3-3 = 'D' Batch3- batch code assigned to paired incisors (first and second incisors) based on the batches in which the incisors were aged by the laboratory that aged the deer when two batches were compared; batch code for pairs (two): 1-2 & 1-3 = 'A', 2-3 & 3-3 = 'B' AdamsBlanchong_Precision of CA.R Content- R file for logistic regression of paired CA ages (AdamsBlanchong_DupAges.csv) in Program R Explanation- code for logistic regression models to determine best 1) batch classification system, 2) on effects of age and batch on certainty code, and 3) on effects of age, certainty code, and batch on the probability of agreement between paired CA age estimates. Also contains code to plot predicted probability of agreement given top-ranked model by AIC *See annotations in R file for further explanation
