Metadata: Model outputs created using the NIS (Non indigenous species) surveillance simulator in 2024
Abstract:
This is the data associated with a surveillance simulator to determine detection time, detection failure and overall survey probability of detection for NIS introduced at seed site(s) with different surveillance efforts (assumes no spread). It may include variation in method detection probability relative to abundance at each site as defined by a detection dynamic. The data is split into two folders TheoreticalSimulations and EmpiricalSimulations. The Empirical_Simulations folder contains its own scripts alongside the data which are derived from the scripts in the main github in order to interact with the empirical risk data. Code is available at `https://github.com/CefasRepRes/C8389-NIS-surveillance-simulator`_. The data is available via Zenodo at `https://zenodo.org/doi/10.5281/zenodo.10355963`_ Publication DOI: 10.3897/neobiota.97.121188 .. _`https://github.com/cefasrepres/c8389-nis-surveillance-simulator`: https://github.com/CefasRepRes/C8389-NIS-surveillance-simulator .. _`https://zenodo.org/doi/10.5281/zenodo.10355963`: https://zenodo.org/doi/10.5281/zenodo.10355963

| Other details | ||
| Internal code | Internally assigned metadata identifier | 9565 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Model outputs created using the NIS (Non indigenous species) surveillance simulator in 2024 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFAS42f4528b-7987-4f79-9be7-a588d8270f02 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS22087 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2024 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2025-04-14 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This study implemented a theoretical surveillance simulator in R to model the relative merit of different surveillance strategies with different levels of focus on NIS risk for NIS detection at one or more sites. Three potential surveillance scenarios were modelled: random, risk-based and heavy risk-based surveillance, each with three distributions of combined NIS risks of introduction and establishment: exponential, random and uniform. An example analysis using model derived NIS risk data was also provided. Sensitivity and elasticity analyses were conducted to identify variables which influence model outputs. The interaction between sampling method detection probability and changes in NIS abundance was modelled. For further details and the scripts used to produce the data for the Theoretical_Simulations please refer to the publication and the github associated with this project `GitHub - CefasRepRes/C8389-NIS-surveillance-simulator: Simulator to determine detection time of NIS introduced at seed site with different surveillance efforts (assumed no spread).`_ .. _`github - cefasrepres/c8389-nis-surveillance-simulator: simulator to determine detection time of nis introduced at seed site with different surveillance efforts (assumed no spread).`: https://github.com/CefasRepRes/C8389-NIS-surveillance-simulator |
