“…Several spiders are known to be more commonly found in areas with a greater human impact (e.g., Damptey et al., 2022; Fraser & Frankie, 1986; Moorhead & Philpott, 2013), and some species actively thrive in these areas due to increased reproductive capacity (Lowe et al., 2014) and enhanced prey capture (Gomes, 2020). Many of the known North American non‐native spiders are synanthropic (e.g., Pholcus phalangioides and P. manueli : Campbell et al., 2020; Cyrtophora citricola : Chuang & Riechert, 2021; Latrodectus geometricus : Vetter et al., 2016; Oecobius navus : Voss et al., 2007), likely due to selective pressures associated with their common introduction pathway as shipping cargo stowaways (Hänggi & Straub, 2016; Nentwig, 2015). While T. clavata shares this proposed introduction pathway (Hoebeke et al., 2015), it is unlike the other species because it is present in both urban and natural environments in its introduced range, which increases the odds of impacts on native communities.…”

Economic and ecological consequences of invasive species make biological invasions an influential driver of global change. Monitoring the spread and impacts of non‐native species is essential, but often difficult, especially during the initial stages of invasion. The Jorō spider, Trichonephila clavata (L. Koch, 1878, Araneae: Nephilidae), is a large‐bodied orb weaver native to Asia, likely introduced to northern Georgia, U.S. around 2010. We investigated the nascent invasion of T. clavata by constructing species distribution models (SDMs) from crowd‐sourced data to compare the climate T. clavata experiences in its native range to its introduced range. We found evidence that the climate of T. clavata's native range differs significantly from its introduced range. Species distribution models trained with observations from its native range predict that the most suitable habitats in North America occur north of its current introduced range. Consistent with SDM predictions, T. clavata appears to be spreading faster to the north than to the south. Lastly, we conducted surveys to investigate potential ecological impacts of T. clavata on the diversity of native orb weaving spiders. Importantly, Trichonephila clavata was the most common and abundant species observed in the survey, and was numerically dominant at half of the sites it was present in. Our models also suggest that there is lower native orb weaver species richness and diversity closer to where T. clavata was initially found and where it has been established the longest, though human population density complicates this finding. This early study is the first to forecast how widely this spider may spread in its introduced range and explore its potential ecological impacts. Our results add evidence that T. clavata is an invasive species and deserves much more ecological scrutiny.

Economic and ecological consequences of invasive species make biological invasions an influential driver of global change. Monitoring the spread and impacts of non-native species is essential, but often difficult, especially during the initial stages of invasion. The Joro spider, Trichonephila clavata (L. Koch, 1878, Araneae: Araneidae), is a large-bodied orb weaver native to Asia, likely introduced to northern Georgia, U.S. around 2010. We investigated the nascent invasion of T. clavata by constructing species distribution models (SDMs) from crowdsourced data to compare the climate T. clavata experiences in its native range to its introduced range. We found evidence that the climate of T. clavata's native range differs significantly from its introduced range and that the most similar climate in North America to its native range is to the north of its current introduced range. We then compared the SDM predictions to current observations of spread. Consistent with predictions, T. clavata appears to be spreading faster to the north than to the south. Lastly, we conducted surveys to investigate potential ecological impacts of T. clavata on the diversity of native orb weaving spiders. Importantly, Trichonephila clavata was the most common and abundant species observed in the survey, and was numerically dominant at half of the sites it was present in. Our models also suggest that there is lower native orb weaver species richness and diversity closer to where T. clavata was initially found and where it has been established the longest, though human population density complicates this finding. This early study is the first to forecast how widely this spider may spread in its introduced range and explore potential ecological impacts of T. clavata, and we call for continued investigation of this invasion's effects.

“…As common and abundant predators, spiders play a central role in natural and agricultural ecosystems (Hogg et al, 2010; Michalko et al, 2019; Nyffeler & Birkhofer, 2017; Pétillon et al, 2020). Yet, the underlying mechanisms of invasions by spiders have only recently started to receive scientific attention (Bauer et al, 2019; Campbell et al, 2020; Chuang & Riechert, 2021, 2022; Mowery et al, 2021, 2022; Narimanov et al, 2022; Narimanov, Hatamli, et al, 2021, Narimanov, Kempel, et al, 2021; Nentwig, 2015), most likely due to the prevalently synanthropic lifestyle and limited evidence for economic damage by spiders (Kobelt & Nentwig, 2008). To our knowledge, the range dynamics and evolution of rapidly spreading spiders are largely unexplored (Chuang & Peterson, 2016; but see Chuang & Riechert, 2021, 2022; Mowery et al, 2021, 2022; Wolz et al, 2020).…”

Aim The continuous spread of invasive species is attributed to demographic processes and high dispersal rates. Both can change and evolve during range expansion, eventually accelerating spread dynamics. Here, we document such an accelerated spread for one of the most invasive spiders in Europe, the dwarf spider Mermessus trilobatus, and test whether dispersal, reproduction or competitive ability is at the source of this pattern. Location Europe. Time period 1981–2021. Major taxon studied Mermessus trilobatus (Arachnida: Araneae: Linyphiidae). Methods First, we collected records from 21 countries across Europe to document the speed of progression of the invasion front over the last 40 years. Second, we collected live individuals from populations in the longest and more recently invaded areas and compared the dispersal propensity of offspring raised under standardized conditions. Third, we compared the reproduction and competitive ability of females derived from the populations of long‐invaded areas against areas with more recent establishment. Results The progression of the invaded range increased from about 150 km in the 1980s to some 400 km between 2010 and 2020. Dispersal‐related behaviour was nearly twice as frequent in offspring from invasion front populations compared to the core area. By contrast, we found no differences in reproduction or competitive ability among the studied populations. Further, neither joint inheritance nor trade‐offs of dispersal, reproduction or competitive ability were identified. Main conclusion As high dispersal is recessively inherited in M. trilobatus, our results suggest that the accelerated invasion is due to the accumulation of dispersive but not more reproductive or competitive genotypes in newly colonized areas. Given the high climatic amplitude of the species in North America, we expect it to spread over the remaining parts of Europe and large parts of Asia in the coming decades. Accelerated range expansion through the evolution of dispersal behaviour could play a role in numerous arthropod invasions worldwide.
