“…On islands, the use of eDNA methods will very likely result in better biosecurity effectiveness due to increased early detection rates and improved IAS surveillance (Herder et al, 2014;Tingley et al, 2019). Smart applications for reporting nature observations are used in citizen science projects to detect, monitor and manage alien species (Mannino and Balistreri, 2018;Roy et al, 2018;Johnson et al, 2020) and satellite data are used via remote sensing for alien species mapping and management (Henderson and Dawson, 2009;Robin et al, 2011;Rocchini et al, 2015;Rivas-Torres et al, 2018). On the other hand, e-commerce has resulted in increased alien species introductions and has emerged as a new pathway of introductions that is difficult to manage (Lenda et al, 2014;Humair et al, 2015), which likely explains why the divergence in opinion was higher for the introduction than for the two other stages of invasion.…”

“…Despite some drawbacks (e.g. incorrect identifications and/or non-standardised and biased sample), validated and opportunistically collected data have already proven its potential, for example, in producing habitat suitability models for elusive bird species (Bradter et al, 2018), in estimating nationwide climatic niches for amphibians and reptiles (Tiago et al, 2017), in producing distribution maps of endangered saproxylic beetles (Zapponi et al, 2016) and in collecting records of alien invasive species (Johnson et al, 2020).…”

The invasive yellow‐legged hornet (Vespa velutina) was first detected in mainland Portugal in September 2011. The lack of information regarding the processes of species spread has hampered the development of adequate measures to mitigate the potential impact of this invasive predator. Crowdsourced data, i.e., information opportunistically reported by citizens, can facilitate the collection of numerous species occurrence records over large spatial scales, which can be valuable to understand the expansion of invasive species. Here, using validated crowdsourced data on the precise location of 49 013 nests, we: (i) update information regarding V. velutina distribution in Portugal; (ii) estimate the species expansion rate; and (iii) analyse the patterns of nests distribution at national and local scales. The species is currently distributed over an area of approximately 57 000 km2, which corresponds to 62% of mainland Portugal. We estimated an average rate of 37.4 ± 13.2 km/year for V. velutina expansion. Vespa velutina nests presented an aggregated distribution and nest density at the urban local‐scale was estimated in 5.4 ± 3.3 nests/km2. The observed decrease in the nearest‐neighbour nest distance over the years suggests that the density of nests has not reached its limit. We advocate that the development of a cheap and rapid method for nest detection and the study of fine‐scale mechanisms leading to V. velutina dispersal are important steps to identify colonisation pathways and plan management approaches aiming to halt species spread and impact in apiaries.

“…Moreover, even when data are public (e.g. citizen science initiatives), lack of data sharing with larger initiatives and databases continues to pose a barrier to implementation of emerging data sources in research and management (Johnson et al 2020). The most effective management strategies will couple an appropriate synthesis of traditional and emerging data sources based on the scope and connectivity of target water-bodies, but this will require a significant investment in web infrastructure to collate, update and disseminate disparate data sources and formats.…”

Prevention of aquatic invasive species is a fundamental management challenge. With hundreds of millions of people participating in fishing trips each year, understanding angler movements that transmit invasive species can provide critical insight into the most effective locations and scales at which to apply preventative measures. Recent evidence suggests that mobile technologies provide new opportunities to understand different types of angler movement behaviour beyond what is possible with infrequently and sparsely conducted in-person boat surveys and mail questionnaires. Here we capitalise on data provided by ReelSonar’s iBobber, a sonar-enabled bobber with over 5 M recorded fishing locations, globally. By quantifying geographic patterns of fishing activities and assessing how these patterns change seasonally, we explore angler behaviour across the entire continental United States in terms of fishing frequency and distance travelled between sites and characterise the attributes of fished ecosystems. We found that iBobber users (anglers) undertook 66,918 trips to 20,049 different water-bodies over a two-year period. Anglers who use iBobber were more likely to visit larger, deeper and more urbanised water-bodies and these water-bodies were over five times more likely to be a reservoir compared to a lake. Inter-water-body travel road distances averaged 93 km (SD = 277 km; range < 1–300 km) and nearly half of these movements occurred over a timespan of two days or less, a timeframe that we show falls well within the desiccation tolerance window of many prevalent plant and animal invasive species. Our study offers novel insight into spatiotemporal patterns of angler behaviour well beyond the geographical and temporal extent of conventional ground-collected approaches and carries important implications for predicting and preventing future transmission of aquatic invasive species via recreational fishing.
