“…Outcomes of this and previous studies on eriophyoid dispersal were drawn from the behaviour of mites held at one particular light, wind speed, temperature and humidity regime. These environmental variables may affect dispersal propensity, distance travelled, locomotor performance or speed 47 – 50 . In particular, temperature-related factors have a large impact on behaviour of ectotherms since it directly affects metabolic rates, and can alter activity patterns or movement speed 47 .…”

Passively dispersing organisms should optimise the time and direction of dispersal by employing behaviours that increase their probability of being successfully transported by dispersal agents. We rigorously tested whether two agriculturally important passively-dispersing eriophyoid species, wheat curl mite (WCM) and cereal rust mite (CRM), display behaviours indicating their readiness to depart from current host plants in the presence of potential dispersal cues: wind, an insect vector and presence of a fresh plant. Contrary to our expectations, we found that both species decreased their general activity in the presence of wind. When exposed to wind, WCM (but not CRM) significantly increased behaviour that has previously been considered to facilitate dispersal (in this case, standing vertically). Our study provides the first sound test of the function of what have been interpreted as dispersal-related behaviours of eriophyid mites. The low proportion of WCM exhibiting dispersal behaviour suggests there may be predisposed dispersers and residents in the population. Moreover, we found that WCM was generally more active than CRM, which is likely a contributing factor to its high invasive potential.

“…Overland dispersal in invasive crayfish species has been reported numerous times 15,24–27 in a number of species (e.g. red swamp crayfish ( Procambarus clarkii ; signal crayfish), including mitten crabs 28 . If faced with unfavourable conditions and/or barriers, crayfish and mitten crabs are known to exit the water to find more suitable habitats and to overcome barriers 15,24,27 .…”

The role of river obstacles in preventing or facilitating the dispersal and establishment of aquatic invasive species is controversial. Novel detection tools like environmental DNA (eDNA) can be used for monitoring aquatic invasive species (AIS) such as the American signal crayfish ( Pacifastacus leniusculus ) and the Chinese mitten crab ( Eriocheir sinensis ), providing information on the effect of barriers on their distribution. We analysed eDNA from both water and surface sediment in three river catchments (Medway, Dee and Stour; Great Britain), with differing levels of connectivity, to determine spatial distribution of the two species, and assessed the effect of barriers on their eDNA detection. Positive eDNA detections were obtained within confirmed sites for both species in all catchments, with evidence of species overlap in the River Medway. Upstream barriers in the Medway positively influenced detection success of mitten crab lower in the catchment while detection success of signal crayfish was higher in the highly fragmented catchment (River Medway). This information on the role of river barriers on AIS distribution and eDNA detection is important for management strategies and for predicting both future dispersal and likelihood of new colonisations in previously uninvaded fragmented catchments.

“…Amphibious behaviour, however, offers not only opportunities for foraging, reproduction and escape from unfavourable conditions, but terrestrial emigration to nearby water bodies (Sayer & Davenport, 1991). This has played an important role in the spread of invasive non-native species (Peterson et al, 2013;Marques et al, 2014;Ramalho & Anastácio, 2014;Fialho et al, 2016). Invasive species can detrimentally affect biodiversity, human health and industry in their introduced range (Mack et al, 2000), and determining their dispersal capacity is paramount for non-native species risk assessments (Johnson & Padilla, 1996).…”

“…Certain species have the capacity to disperse up to 1 km overland and move between isolated water bodies (Lutz & Wolters, 1999;Ramalho & Anastácio, 2014;Fialho et al, 2016), where they act as ecosystem engineers and interact with organisms on multiple trophic levels (Gherardi, 2007;Strayer, 2010;James et al, 2015a). Because of their success and impact, invasive crayfish are considered a major cause of biodiversity loss (Lodge et al, 2000;Manchester & Bullock, 2000).…”

Transmission and terrestrial dispersal of non-native ectosymbionts on invasive crayfish

et al. 2018

Symbionts are a fundamental component of biological systems, and their survival is highly dependent on transmission and host movement. Ectosymbionts of amphibious animals face the added challenge of having to survive dramatic environmental changes as their hosts cross ecosystem boundaries. Within freshwaters, crayfish are amongst the most widespread invasive species that readily disperse overland and are host to a wide range of ectosymbionts. Relatively little is known about the transmission of these ectosymbionts, including their ability to survive overland host migration. Here, we assessed terrestrial emigration and both inter-and intra-specific transmissions of Xironogiton victoriensis, a nonnative branchiobdellidan (Annelida: Clitellata) recently found on invasive signal crayfish (Pacifastacus leniusculus) in the UK. These branchiobdellidans tolerated desiccation and did not alter host terrestrial behaviour. Transmission was rapid between natural signal and novel virile (Orconectes cf. virilis) crayfish hosts, with host interactions facilitating transmission.Thus, branchiobdellidans can disperse via amphibious host behaviour and readily infect novel hosts. These traits facilitate symbionts' survival and provide access to additional dispersal pathways that are likely to aid transmission.
