In this study of three years of monitoring, we assessed the spatio-temporal distribution, diversity and relative abundance of invasive and native rodents in a West African autonomous port. Data useful for interpreting the results were collected during each sampling campaign at each of the surveyed sites.

Details for each dataset are provided in the README file.

Datasets included:

1. Small mammal captures by wire and shermans traps. Number of small mammals caught per trapping campaign.
2. Sampling design. Description of the characteristics of each sampled site.
3. Trapping and identification of small mammals Sampling protocol in detail. Morphological identification using morphometric measurements (body mass, length of body, tail, hind leg and ear).
4. Trapping data analysis Trap-specific and species-specific trapping effort under the R software (R Core Team, 2011). Species-specific relative abundance according under the R software (R Core Team, 2011). Specific diversity using EstimateS v.9.1.0. Co-occurrence analyses using the program Pairs v.1.0. Occupancy modelling under R using the unmarked v.0.13-2 package.

There are not missing values.
