Code and data to replicate the article "Climate change effect on Octopus maya (Voss and Solís-Ramírez, 1966) suitability and distribution in the Yucatan Peninsula, Gulf of Mexico: A correlative and mechanistic approach".

In order to replicate the results of this study, open the octopusNiche.Rproj and follow the order provided in the code folder:

• 0. 0_auxiliar_functions.R (You do not need to run this code. It will be called from the following scripts).
• 1. 1_niche_model_maxent.R
• 2. 2_binary_maps.R
• 3. 3_physiology_maps.R

All the scripts have comments for an easy understanding of the process.

Nevertheless, you must download maxent software from: https://biodiversityinformatics.amnh.org/open_source/maxent/. After that, you have to create a folder named maxent, inside this folder there will be: maxent.bat, maxent.jar, maxent.sh, readme.txt.

Also, you need to install kuenm package. Please follow the instructions provided in this link: https://github.com/marlonecobos/kuenm#installing-the-package

The file structure of this project is:

• code

• dataset

• G_variables

• M_variables

• maxent

• octopusNiche.Rproj

• README.md

If you want to replicate the maps or other plots of the paper, contact to Luis Enrique Angeles-González ([email protected]) or Josymar Torrejón-Magallanes ([email protected]).

For Mac users: Before install the kuenm package, follow these instructions to install Xcode on your Mac: https://clanfear.github.io/CSSS508/docs/compiling.html Xcode will replace RTools.

If you find any problem in the code, please add this at the Issues section of the github.
