title: Growth and fitness measures of cytoplasmic male sterility (CMS) of Physa acuta

description: We compared male fitness (male sterility, seminal vesicle area, and number
 of spermatozoa), female fitness (eggs production), growth rate (body mass
 and shell length), and whole body metabolism between the three mitotypes
 (D male-sterile individuals, N normal hermaphrodite, and K restored
 hermaphrodite) at two temperatures (18°C and 25°C).
description: # Growth and fitness measures of CMS *Physa acuta*
 [https://doi.org/10.5061/dryad.f1vhhmh5r](https://doi.org/10.5061/dryad.f1vhhmh5r) The data contains measurement of the following traits: * male fitness (male status [sterile or fertile], number of spermatozoa and seminal vesicle area); * female fitness (egg production);  * growth rate (body mass and shell length);  * whole body metabolism. We compared all these traits between the three groups : mitotypes D (male-sterile), mitotype N (normal hermaphrodite) and mitotype K (restored hermaphrodite) at two temperatures : 18°C and 25°C. ## Description of the data and file structure There are 6 data files (named "**data_*xxxxx*.txt**") and 1 R script (named "**scripts_CMSxTemperature_Physa acuta**"). ##### More informations about the data files: There are **empty cells** in some columns, which correspond to missing data, i.e., data that were not collected (e.g., the snail individual died before measurement). These two following dataset contains the 12 variables (12 column total):  * **data_repro.txt** contains the measurements of the traits mentioned above for the 50 individuals per mitotype (regardless of their male status). * **data_sf.txt** contains data of N and K male-fertile individuals (normal hermaphrodite and restored hermaphrodite, respectively) and D male-sterile individuals. * temperature (in celsius degree (°C)) * mitotype: N for normal hermaphrodite, K for restored hermaphrodite and D for male-sterile * individu: the individual's number * poids: the whole body mass (shell + body) in g * taille: the maximal shell lenght in mm * taux de croissance poids: growth rate from the body mass (in g/day) * taux de croissance taille: growth rate from the shell length (in mm/day) * pigmentation ponte albinos: pigmentation of the offspring produced by the albino partner used to determine male status (1 = pigmented eggs; 0 = albinos) * sterile_fertile: male status (sterile or fertile according to the pigmentation of the offsprings of the albino partner) * n oeufs focal: number of eggs produced by the focal individual * surface vs: seminal vesicle area (in mm²) * MO2 / pds: in vivo metabolic rate (in mgO2.h-1.mg snail-1) The following dataset contains data of N and K male-fertile individuals (normal hermaphrodite and restored hermaphrodite, respectively) and D male-sterile individuals. * **data_sf_egg_predicted_values.txt** contains variables: * temperature (in °C) * mitotype * individu * poids (in g) * n oeufs focal * v predites mod complet: the predicted values of the global model * v predites: the predicted values of the simplified model * **data_sf_spz.txt** contains variables: * temperature (in °C) * mitotype * individu * nb spz: number of spermatozoa produced by the focal individual (two counts per individual) * surface vs (in m²) * poids total: the whole body mass (shell + body) in g * **data_sf_spz_predicted_values.txt** contains variables: * temperature (in °C) * mitotype * individu * poids total (in g) * v.predites: the predicted values of the simplified model * moy.nb.spz: means of the 2 counts per individual * **data_sf_vesicle_predicted_values.txt** contains variables: * temperature (in °C) * mitotype * individu * poids (in g) * surface vs (in mm²) * v predites mod complet * v predites
