Variable definitions for RPSITE_SB_baylisascaris_data.csv. Measurements on Baylisascaris worms recorded in RPSITE_SB_parasites_data.csv and removed from raccoons listed in RPSITE_SB_hosts_data.csv. When data entries are restricted (e.g. “M” or “F” or “U”), acceptable values are listed in the Definition.

Variable	Definition	Format
Project_host_ID	Code assigned to the animal at time of dissection.	numeric
Worm_ID	Worm ID, each Baylisascaris worm is assigned a unique ID code which starts with the raccoon number (R#) followed by the worm number, generating a code in the from R#W#. If “0” no Baylisascaris were found in that host.	text or numeric
Location	Location in host small intestine, measured in centimeters from the junction with the stomach. For worms found in stomach, location is listed as stomach. These data were never used for analyses as worms can migrate after host death and it is unclear how reliable these measurements are.	text or numeric
Mature	Reproductive status of each worm. “A” for adult with mature gonads present, “U” for immature, without developed gonads.	text
Sex	Sex of worm. “M” for Male, “F” for female, “U” for uncertain. Uncertain typically used for immature worms without characteristic male and female tail morphology (or gonads)	text
Weight	Whole worm wet weight in grams. Worms were blotted on a paper towel and weighed on an electric balance; weight is in grams to the nearest 0.001g. Recorded only for a subset of worms.	numeric
Length	Full length of worm, measured to the nearest millimeter using a ruler.	numeric
Width	Width of worm at widest point, measured to the nearest hundredth of a millimeter using electronic calipers. Recorded only for a subset of worms.	numeric
Uterus_weight	Weight of uterus dissected out of female worms in grams. Recorded only for a subset of female worms	numeric
