Effects of nest-site availability on male-male competition and associated costs of nest site maintenance and paternal care in a resource-defense species

Effects of nest-site availability on male-male competition and associated costs of nest site maintenance and paternal care in a resource-defense species This repository contains the .csv files used for the statistical analyses of the study "Effects of nest-site availability on male-male competition and associated costs of nest site maintenance and paternal care in a resource-defense species". In case of questions, please email Laís A. Grossel: [e-mail] Data files and structure We have files for the analysis with field and experimental data. With the file field.csv we tested the probability of males obtaining a nest and receiving eggs from females. In this file, we have the headers: maleID: identity of males in the field DSW: dorsal scute width, in mm mass: to the nearest 0.001 g nest_possession: with 2 levels: 0 if the male did not possess a nest and 1 if the male possessed a nest nest_opening: in cm parental_status: with 3 levels: 0 if the male did not have a nest, 1: if the male had a nest but no eggs, and 2: if the male had a nest and eggs With the file experiment_nests.csv we tested predictions related with the nest possession. In this file, we have the headers: terrariaID: identity of the 14 terraria (containing 4 or 8 nests) exp_group: experimental group, with 2 levels of nests availability: low (4 nests per terraria) and high (8 nests per terraria) nestID: identity of the nests occupation: if the nest was once occupied during the experiment, with 2 levels: 0 if it was never occupied and 1 if it was occupied at least once occupied_scans: number of scans with any male inside the nest vacant_scans: number of scans without any male inside the nest total_scans: total number of observation scans owners: number of different owners of the nest (at least 6 consecutive scans) turnover: if there was at least a substitution of the nest owner without figths, with 2 levels: 0 if there was not any substitution and 1 if there was a substitution turnovers_number: number of substitutions of the nest owner without figths takeover: if there was at least a takeover attempt of the nest after figths, with 2 levels: 0 if there was not any attempt and 1 if there was an attempt takeovers_number: number of takeover attempts of the nest after figths fight: if there was at least a figth inside or close to the nest, with 2 levels: 0 if there was not any figth and 1 if there was a figth fights_number: number of figths inside or close to the nest canibalism: if there was at least a cannibalism event inside the nest, 2 levels: 0 if there was not any cannibalism event and 1 if there was a cannibalism event canibalism_number: number of cannibalism events (= number of eggs cannibalized) inside the nest With the file experiment_males.csv we tested predictions related to the males owners. In this file, we have the headers: terrariaID: identity of the 14 terraria (containing 4 or 8 nests) exp_group: experimental group, with 2 levels of nests availability: low (4 nests per terraria) and high (8 nests per terraria) maleID: identitity of the males DSW: dorsal scute width, in mm nest_possession: with 2 levels: 0 if the male never possessed a nest during the experiment and 1 if the male possessed a nest at least once (6 consecutive scans) nestID: identity of the nest possessed by the male inside_scans: number of scans with the male inside his nest outside_scans: number of scans with the male outside his nest total_scans: total number of scans in which the male was the owner of the nest takeover: if the male suffered a takeover attempt of his nest, with 2 levels: 0 if the male did not suffer any attempt and 1 if the male suffered an attempt eggs: if the male received eggs from a female, with 2 levels: 0 if the male did not receive eggs and 1 if the male received eggs eggs_number: number of eggs received cannibalism: if the owner male cannibalized the eggs inside the nest, 2 levels: 0 if the male did not cannibalize eggs and 1 if the male cannibalized eggs cannibalism_number: number of eggs cannibalized by the owner male With the file fights-takeovers.csv we tested predictions related with nest takeovers. In this file, we have the headers: terrariaID: identity of the 14 terraria (containing 4 or 8 nests) exp_group: experimental group, with 2 levels of nests availability: low (4 nests per terraria) and high (8 nests per terraria) nestID: identity of the nest possessed by the male focalID: identitity of the focal males (the owner nest) DSW: dorsal scute width, in mm fight: if the male was involved in at least a figth, with 2 levels: 0 if the male was not involved in any figth and 1 if the male was involved in a figth takeover: if the male suffered a takeover attempt of his nest, with 2 levels: 0 if the male did not suffer any attempt and 1 if the male suffered an attempt. Obs: the nest takeover always happens after a fight. If there was a takeover, then there was a fight too. res_focal: result of the figth or takeover for the focal male, with 2 levels: 0 if the focal male did not lose the figth or the nest and 1 if the focal male lost the figth or the nest intruderID: identity of the intruder male involved in the figth or the takeover with the owner male intruder_DSL: dorsal scute width of the intruder male, in mm dyad: identity of the two individuals involved in the figth or takeover (owner male and intruder male) DSW_difference: difference between the dorsal scute width of the dyad (focal male minus intruder male)
