Ecological features of exotic Vespula wasps (Hymenoptera: Vespidae) invading the southernmost UNESCO Biosphere Reserve

When ice and sea are not barriers for flies: First report of Trichocera maculipennis (Diptera) in South America

“…dispersal ranges (Hughes et al, 2019(Hughes et al, , 2023. For instance, during the last decade, yellow jackets (wasps) and the European bumblebee have become established on Navarino Island (Rendoll-Carcamo et al, 2017;Rendoll-Cárcamo et al, 2022), while increasing numbers of non-native invertebrates have been reported from the Maritime Antarctic (Greenslade & Convey, 2012;Hughes et al, 2023).…”

“…Human activities in the MSA and Maritime Antarctic regions have significantly increased connectivity in recent years and have the potential to transport species far beyond their natural dispersal ranges (Hughes et al, 2019, 2023). For instance, during the last decade, yellow jackets (wasps) and the European bumblebee have become established on Navarino Island (Rendoll‐Carcamo et al, 2017; Rendoll‐Cárcamo et al, 2022), while increasing numbers of non‐native invertebrates have been reported from the Maritime Antarctic (Greenslade & Convey, 2012; Hughes et al, 2023).…”

“…Although these regions remain relatively free of direct human impact, they face rapidly growing development pressures combined with climate change and the introduction of non‐native species (Convey & Peck, 2019; Rozzi et al, 2012). Increasing industrial development, trade, tourism, and scientific activities render these regions vulnerable to the introduction of non‐native species (Bartlett et al, 2020; Frenot et al, 2005; Hughes et al, 2015; Lebouvier et al, 2020; Rendoll‐Cárcamo et al, 2022). The MSA ecoregion comprises a mountainous archipelago shaped by erosion during repeated glacial cycles, which forged a diverse range of terrestrial and freshwater ecosystems characterised by sharp altitudinal and precipitation gradients (Contador et al, 2015; Rendoll Cárcamo et al, 2019).…”
