“…The best documented examples of aquatic invertebrate invasions include the introduction of the zebra mussel Dreissena polymorpha in North America and the cercopagids Bytotrephes longimanus and Cercopagis pengoi in Europe and North America via release of ballast water (Hebert et al, 1989;Panov et al, 2004). Once introduced, these species were able to spread quickly via boating and angling equipment (Jacobs and MacIsaac, 2007). The movement not only of ballast water, but also ballast sediment, containing dormant propagules, may pose a risk of introduction (Bailey et al, 2005).…”

ABSTRACT1. Several human activities, such as actions for nature conservation, research and recreational activities, are closely associated with inland aquatic habitats that are usually considered as isolated island habitats. In this study, the possibility of unintentional dispersal of aquatic invertebrates among water bodies via footwear and motor vehicles was investigated.2. Mud samples collected from boots and from the tyres and wheel cases of cars used for field work by biologists (Camargue, Southern France) were hatched under laboratory conditions and also checked for the presence of unhatched propagules. A large number of organisms hatched and invertebrate propagules from a wide range of taxa were encountered (including Artemia, freshwater large branchiopods, Cladocera, Ostracoda, Rotifera, Turbellaria, Nematoda, etc.). The results also demonstrated that different research groups tend to transport the aquatic invertebrates typical for their respective study systems.3. Human dispersal of aquatic invertebrates has been studied mainly on large continental scales, such as in the case of transoceanic transport via ballast water in ships. This study provides evidence that dispersal via footwear and motor vehicles may result in frequent dispersal of aquatic invertebrates on a local scale, and we presume also occasionally over longer distances. Given the rapid spread of invasive zooplankton species (e.g. Artemia franciscana encountered in this study), we promote caution and recommend cleaning before transport of any equipment which comes in contact with water or aquatic sediment.

“…Man undoubtedly remains unrivalled when it comes to transporting vast numbers of exotic organisms including many freshwater invertebrates on a global scale (Havel & Shurin, 2004; Green et al. , 2005; Jacobs & Mac Isaac, 2007; Waterkeyn et al. , 2010a,b).…”

“…Inspired by Darwin's pioneer work, and propelled by productive ornithological research groups, current literature related to vectormediated dispersal of freshwater organisms considers waterbirds as the most important natural dispersal vectors (Frisch, Green & Figuerola, 2007;Green et al, 2008;Brochet et al, 2010a) responsible for colonisation and exchange of propagules among isolated unconnected freshwater habitats. Man undoubtedly remains unrivalled when it comes to transporting vast numbers of exotic organisms including many freshwater invertebrates on a global scale (Havel & Shurin, 2004;Jacobs & Mac Isaac, 2007;Waterkeyn et al, 2010a,b). Still, waterbirds firmly hold the second place in the vector hall of fame and are held responsible for most long-distance dispersal events of freshwater invertebrates for which humans cannot be blamed (Brendonck, Thiery & Coomans, 1990;Figuerola, Green & Michot, 2005;Muñ oz et al, 2008).…”

Passive external transport of freshwater invertebrates by elephant and other mud-wallowing mammals in an African savannah habitat

1. Recent findings hint at the potential importance of mammals affecting the spatial dynamics of aquatic organisms in areas where mammals live in close association with water. Perhaps the most iconic example of such an environment is the African savannah. 2. We investigated dispersal patterns of freshwater organisms among a set of temporary ponds in SE Zimbabwe to test the hypothesis that large mammals, and particularly African elephants (Loxodonta africana), can be important vectors of aquatic organisms. Dispersal kernels were reconstructed by hatching mud collected from 'rubbing' trees located at increasing distances from a set of isolated ponds. To assess the relative importance of other mammalian vectors, the vertical distribution of mud on rubbing trees was mapped and related to the body size of candidate vector species. 3. Laboratory hatching of mud samples revealed large numbers of propagules of 22 invertebrate taxa as well as some aquatic macrophytes. Dispersing communities reflected source communities and diverged with increasing distance from the source. Both dispersal rates and richness of transported taxa decreased significantly with dispersal distance. No indications for differences in dispersal capacity among propagule types were detected. Instead, common propagules were more likely to travel greater distances. Most mud was attached to trees at heights >1.5 m, implicating elephants as the dominant vector. Vertical distributions of tree mud, however, also revealed clustering at heights up to 50 cm and 90-120 cm corresponding to the height of warthog, rhinoceros and buffalo, respectively. Finally, variation in the vertical distribution of mud on trees in combination with differences in vector vagility suggests that local differences in vector species composition may affect passive dispersal dynamics of aquatic organisms. 4. Based on vagility and vector load, mud-wallowing mammals emerge as highly effective vectors that, in some areas, may be more important in transporting aquatic organisms than traditionally recognised vectors such as waterbirds. Since most large-and medium-sized mammals currently have restricted geographic distributions, it is likely that mammalmediated dispersal was more important in the past.

“…For planktonic NIS such as Cercopagis , management options may include education of recreationalists through awareness of invaded lakes in the Finger Lakes region; inspecting fishing lines or water‐based vectors such as bait buckets, live wells or bilge water for animals; and washing boats and trailers after emerging from invaded lakes. Commercial solutions such as the development of fishing lines that prevent Cercopagis attachment may prove highly effective (Jacobs & MacIsaac, 2007).…”

Aim Predictions of spread of non‐indigenous species allow for greater efficiency in managing invasions by targeting areas for preventative measures. The invasion sequence is a useful concept in predictions of spread, as it allows us to test hypotheses about the transport and establishment of propagules in novel habitats. Our aims are twofold: (1) to develop and validate multi‐stage invasion models for the introduced fishhook waterflea, Cercopagis pengoi, and (2) to assess how variability in the transport patterns of the propagules influences the accuracy and spatial extent for predictions of spread. Location New York State, USA. Methods We developed a two‐stage model for the spread of C. pengoi. First, we developed a stochastic gravity model for dispersal based on surveys of recreational boat traffic in New York State as a proxy for propagule pressure. We then modelled the probability of establishment based on predicted levels of propagule pressure and measures of lakes’ physicochemistry. In addition, we used Monte Carlo simulations based on the gravity model to propagate variability in boater traffic through the establishment model to assess how uncertainty in dispersal influenced predictions of spread. Results The amount recreationalists were willing to spend, lake area and population size of the city nearest to the destination lake were significant factors affecting boater traffic. In turn, boater traffic, lake area, specific conductance and turbidity were significant predictors of establishment. The inclusion of stochastic dispersal reduced the rate of false positives (i.e. incorrect prediction of an invasion) in detecting invasions at the upper 95% prediction interval for the probability of establishment. Main conclusions Combinations of measures of propagule pressure, habitat suitability and stochastic dispersal allow for the most accurate predictions of spread. Further, multi‐stage spread models may overestimate the extent of spread if stochasticity in early stages of the models is not considered.
