Data from: Born in heterogenous landscapes: birth timing, body mass and growth of roe deer (Capreolus capreolus) fawns in contrasting habitats

# Born in heterogenous landscapes: birth timing, body mass and growth of roe deer (Capreolus capreolus) fawns in contrasting habitats. ## **Data:** **Data for body mass/habitat analyses:** We investigated the effects of habitat, sex and birth date on fawn's body mass during the 20 first days of their lives. To do so, we used the following data to perform the analyses, by building generalized additive models (GAM): *Data_gamm_models_whole_dataset.rds* We performed the same analyses with fawns who survived until the set of autumn only: *Data_gamm_models_alive_dataset.rds* **Data for phenology/parturition dates analyses:** Data with the birth dates, including those calculated from the age estimation during fawn captures, and those estimated from GPS monitoring of females in spring, for each habitat. *birth_date_Forest.rds* *birth_date_Mixed.rds* *birth_date_Open.rds* ## **Data:** *Script_body_mass_habitat_birth_date:* Script used to build GAM from the data: "Data_gamm_models_whole_dataset.rds" and "Data_gamm_models_alive_dataset.rds" to analyse the effects of habitat, sex and birth date on fawn's body mass during the 20 first days of life. The script also contains the code for the model selection using AIC. *Script_parturition_dates_analyses:* This script contains the code for analyses related to birth timing with the estimation of the median date of birth in each habitat, the building of the density plots, and the Mood's median test, performed to compare the median dates of births between the habitats. ## Description of the data and file structure **Data for body mass/habitat analyses:** "id": identity of the fawn "Capture_date": Date of capture of the fawn, in the fromat : *yyyy-mm-dd* "Capture_Julian_date": Date of capture of the fawn, in the julian date format (January 1st = 1, January 2nd =2,...) "Body_mass": the body mass of fawns at the date of the capture, measured using a spring balance (in kg) "age": estimation of the age of fawn at capture (in days) "birth_day": day of birth of the fawn, calculated from the date of capture and age estimation (in julian date) "sex": the sex of the fawn (Male/Female) "cohort": the cohort in which the fawn belongs (here, the year of birth) "habitat": habitat where the fawn was captured (Open, Mixed, Forest) **Data for phenology/parturition dates analyses:** "id": identity of the individual (fawn, if it is a name, in character / mother, if it is constituated of numbers) "birth_date": day of birth of the fawn, calculated from the date of capture and age estimation OR parturition date estimated from the GPS of mothers (see id to know which), format = *yyyy-mm-dd* "habitat": habitat where the individual was captured (Open, Mixed, Forest), in spring for fawns, in winter for mothers "birth_julian_date": day of birth of the fawn, calculated from the date of capture and age estimation OR parturition date estimated from the GPS of mothers (see id to know which), format = *Julian date* ## Code/Software We performed our analyses using R, and RStudio.
