Data from: Costs of injury for scent signalling in a strepsirrhine primate, Harris, RL, Boulet, M, Grogan, KE, Drea, CM, Scientific Reports, 2018. Column heading descriptions - metadata: All columns: L = left dowel; R = right dowel Recipient = odour recipient (using institution name); Date = date bioassay conducted; Trial.no = the nth bioassay the recipient animal had participated in as part of this study; Donor = donor animal (using institution name); Donor.Sex = sex of the donor animal; Donor.Season = season in which the odorant sample was collected from the donor; L.dowel.ID = unique ID of sample assigned to the left dowel; L.dowel.state = injury status (injured or not injured, ‘control’) of the donor animal assigned to the left dowel; L.Age = relative age of the odorant sample assigned to the left dowel (i.e. which of each pair of odorants is the older or newer) Column heading descriptions – behavioural responses: lm = lick scent mark (seconds); #lm = lick scent mark (counts); ls = lick substrate, i.e. dowel (seconds); #ls = lick substrate, i.e. dowel (counts); pr = time spent in proximity (seconds); sm = sniff scent mark (seconds); #sr = shoulder rub (counts); ss = sniff substrate, i.e. dowel (seconds); wm = wrist mark (seconds); #wm = wrist mark (counts); tm = tail mark; bi = bites; prox.total = total time spent in proximity to dowel.
