Overview of the Spotted Lanternfly Paninvasion Severity Research Compendium
Welcome to the Research Compendium Overview for “Paninvasion severity assessment of a U.S. grape pest to disrupt the global wine market” (https://doi.org/10.1038/s42003-022-03580-w). This overview aims to outline the contents of the compendium to ensure that the study is transparent and reproducible.
This compendium follows the paper structure, which assesses the risk of a paninvasion of Lycorma delicatula, the spotted lanternfly (SLF). This emerging invasive pest was recently introduced to the U.S. and demonstrates a preference for feeding on agriculturally important crops, including grapes (Urban (2020)). As it continues to spread, the severity of SLF paninvasion can be thought of in much the same way as emerging infectious diseases. Therefore, we adapt a framework from the epidemiologic literature (Reed et al. (2013)) and merge it with existing invasion ecology theory (Blackburn et al. (2011)) to determine the intensity of a SLF paninvasion.
Our adapted framework determines how closely three (3) invasion potentials align:
We ascertain the strength of alignment at both a domestic (U.S. states) and global (countries) scale. With the resulting alignments, we assign the overall risk of a paninvasion by SLF by calculating the relationship between predicted impact potential to grape production and the market size for the wine industry. Of note, large data for this study are kept separately in a Dryad repository (https://doi.org/10.5061/dryad.msbcc2g1b). Lastly, we deploy a public-facing visualization app of our assessment with Google Earth Engine (https://ieco.users.earthengine.app/view/ieco-slf-riskmap).
The research compendium is organized into several Analyses (or vignettes) that can be accessed via the top bar of this site. Each analysis aims to illuminate the process by which we obtained, prepared, or visualized our results. Currently, the compendium contains the following articles:
Step 1: Estimate Invasion Potentials
Step 2: Calculate Alignment Correlations
Step 3: Quantify Paninvasion Risk
