MS Reference Number: OECO-D-15-00685 MS Dryad ID: OECO-D-15-00685 MS Title: Land colonisation by fish is associated with predictable changes in life history MS Authors: Platt, Edward; Fowler, Ashley; Ord, Terry MS Journal: OECOLOGIA **FILE NAME AND CONTENT** PLATT-OECOLOGIA-2016-OECO-D-15-00685_growth.txt - data on the age and size of female fish for six species of Blennidae from Guam **FILE STRUCTURE AND UNITS OF MEASUREMENTS** The file is a tab delimited text file. There are no missing values. Column headings are in the following order and format: species - The species name of the fish examined. lifestyle_rating - An estimate of the general level of amphibious behaviour exhibited by a species, ranging from 0 (largely aquatic) to 3 (exclusively terrestrial). age_days - An estimate of the age of a female based on microincrement otolith counts. standard_length_mm - The standard length of a female in millimetres, based on the length from the anterior of the upper jaw to the caudal peduncle. **FILE NAME AND CONTENT** PLATT-OECOLOGIA-2016-OECO-D-15-00685_ovary.txt - data on the weight of ovarian tissue, reproductive status and size of female fish for six species of Blennidae from Guam **FILE STRUCTURE AND UNITS OF MEASUREMENTS** The file is a tab delimited text file. There are no missing values. Column headings are in the following order and format: species - The species name of the fish examined. lifestyle_rating - An estimate of the general level of amphibious behaviour exhibited by a species, ranging from 0 (largely aquatic) to 3 (exclusively terrestrial). standard_length_mm - The standard length of a female in millimetres, based on the length from the anterior of the upper jaw to the caudal peduncle. ovarian_weight_g - The wet weight of the ovaries in grams. probable_latest_egg_stage - The latest egg stage found in ovaries that was used to estimate the reproductive status of a female. **FILE NAME AND CONTENT** PLATT-OECOLOGIA-2016-OECO-D-15-00685_eggnumber.txt - data on the number of eggs and size of female fish for six species of Blennidae from Guam **FILE STRUCTURE AND UNITS OF MEASUREMENTS** The file is a tab delimited text file. There are no missing values. Column headings are in the following order and format: species - The species name of the fish examined. lifestyle_rating - An estimate of the general level of amphibious behaviour exhibited by a species, ranging from 0 (largely aquatic) to 3 (exclusively terrestrial). standard_length_mm - The standard length of a female in millimetres, based on the length from the anterior of the upper jaw to the caudal peduncle egg_number - The largest total number of eggs across egg development stages found in ovaries **FILE NAME AND CONTENT** PLATT-OECOLOGIA-2016-OECO-D-15-00685_eggsize.txt - data on the average size of eggs, development stage of those eggs and size of female fish for six species of Blennidae from Guam **FILE STRUCTURE AND UNITS OF MEASUREMENTS** The file is a tab delimited text file. There are no missing values. Column headings are in the following order and format: species - The species name of the fish examined. lifestyle_rating - An estimate of the general level of amphibious behaviour exhibited by a species, ranging from 0 (largely aquatic) to 3 (exclusively terrestrial). standard_length_mm - The standard length of a female in millimetres, based on the length from the anterior of the upper jaw to the caudal peduncle. mean_egg_size_micrometre - The average area of eggs (in micrometers) for the latest egg stage found in the ovaries. egg_stage - The egg development stage associated with the estimated egg number, based on a classification scheme described in Table S2 of the paper. **DATA COLLECTOR** Specimens and life history data were collected and compiled by Edward R.
