CODE INFORMATION

Libraries and functions. List of required libraries.

Figures data. Needed data files and objects to produce all figures.

Update aquamapsdata. This script contains the code to update the local SQL data repository containing the data from AquaMaps.

1. Environmental suitability and degree of niche overlap. This script contains the code needed to obtain the environmental suitability (Component II) and degree of niche overlap (Component III), for each NIS at each half-degree cell.

2. Connectivity. This script corresponds to the calculation of the connectivity between source and recipient areas (Component I), from single port-to-port connections to aggregated values at a province level. Calculations were based on the work of Seebens et al (2013).

3. NIS establishment risk calculation. This script corresponds to the calculation of NIS establishment risk integrating the three previous components.

4. Global patterns of risk (Fig 1-4; Fig S1-3; Table S1). This script contains all the code related with the exploration of global risk patterns (Fig. 1), summary of risk in each realm (Fig. 2), decomposing the risk (Fig. 3) and mapping the patterns of contribution for each single component (Fig. 4). In addition, supplementary figures and tables showing other descriptors of risk (mean and sd; Fig. S1), the main source regions of NIS and cells included (Fig. S2), relationship between aggregated and mean risk (Fig. S3) and summary of risk and components values for each NIS (Table S1)

5. Cumulative impacts, MPAs and risk (Fig 5; Fig S4; Table S2). This script contains all the code needed to produce the GAMMs exploring the relationship between cumulative human impacts and establishment risk (Fig. 5, Table S2), as well as the relationship between risk and MPA presence (Fig. S4).

6. Comparison of risk with established NIS (Fig 6, Fig S5, Table S3). This script contains all the code needed for the comparison with the risk scores obtained and the current ranges of established NIS extracted from WRiMS (Fig. 6, Fig. S5, and Table S3)
