rather overlooked means of migration occur in insects, and in non-insect terrestrial arthropods. These include: aerial transport without powered flight (with or without the use of silk), pedestrian and waterborne migration, wind-propelled migration on the surface of water, and phoresy. ('Parasitic dispersal,' the movement of true parasites in or between their hosts, is outside the scope of this paper.) There is a large body of literature on some of these topics (e.g. phoresy in mites), so the current paper will be illustrative rather than comprehensive.The movements by which animals are able to change their physical location can be categorized behaviourally into 'station-keeping' movements (e.g. foraging), 'ranging,' and migration [2]. The present review is concerned with migratory movements, and we adopt the widely-accepted behavioural definition of this process formulated by J.S. Kennedy [6]:"Migratory behaviour is persistent and straightened-out movement effected by the animal's own locomotory exertions or by its active embarkation on a vehicle. It depends upon some temporary inhibition of station-keeping responses but promotes their eventual disinhibition and recurrence." Abstract: Animal migration is often defined in terms appropriate only to the 'to-and-fro' movements of large, charismatic (and often vertebrate) species. However, like other important biological processes, the definition should apply over as broad a taxonomic range as possible in order to be intellectually satisfying. Here we illustrate the process of migration in insects and other terrestrial arthropods (e.g. arachnids, myriapods, and non-insect hexapods) but provide a different perspective by excluding the 'typical' mode of migration in insects, i.e. flapping flight. Instead, we review non-volant migratory movements, including: aerial migration by wingless species, pedestrian and waterborne migration, and phoresy. This reveals some fascinating and sometimes bizarre morphological and behavioural adaptations to facilitate movement. We also outline some innovative modelling approaches exploring the interactions between atmospheric transport processes and biological factors affecting the 'dispersal kernels' of wingless arthropods.

“…This cosmopolitan species has also been recorded from widely separated locations along the Antarctic Peninsula as far south as Léonie Island (Greenslade 1995). Hypogastrura viatica is capable of dispersal on floating marine debris (hydrochory) and can undergo its whole development under water (Witteveen and Joose 1988). It occurs on all subantarctic islands except for Heard Island, and has been shown to be sufficiently homogenous in the COX1 gene, at least in southern regions, for it to be considered a single species (Greenslade et al 2011).…”

Three exotic species of Collembola are here identified in collections made during surveys on subantarctic South Georgia in the summers of 2005/2006 and 2009/2010.Previously, only two exotic species of Collembola were known from the island. Increased visitation by tourists, research and maintenance personnel seems an obvious cause despite strict quarantine controls imposed on all visitors. The biology, habitat and distribution of the new species records indicated that fresh vegetables, imported in past years, were their likely means of dispersal to the island. A risk analysis based on their current distribution and ecology was conducted for exotic collembolan species that could invade South Georgia. Pathway analysis of the species with the highest risk scores suggested additional quarantine management protocols could include fumigation of imported fresh food, and this is recommended to minimise the risk of further invasions. A review of exotic Collembola in the Antarctic and subantarctic is provided and the biological traits of Collembola are discussed in relation to their invasion potential.

“…1) (Thibaud et al 2004), but there are also some scarce inland records from wet habitat (Fjellberg 1998). H. viatica is adapted to regular flooding; individuals can float on the water surface, on which they can survive up to 70 days and quickly colonize emerging parts of the green beach after flooding (Van Wingerden et al 1981;Witteveen 1986). The second dominant collembolan, I. riparia, is a strictly hydrophilous species (Witteveen 1986).…”

Interaction Milieu Explains Performance of Species in Simple Food Webs along an Environmental Gradient

Species interact with each other in a complex network of relationships that can be modeled as an interaction milieu, i.e. a biotic background with which the species interacts. The interaction milieu is given by the frequency distribution of traits that are important to a given interaction; hence this approach provides a direct link between organism performance, abiotic environmental conditions and interspecific interactions. In this study, we investigate how performance of component species is affected by the interaction milieu along an environmental gradient. We specifically addressed two questions: 1) can the interaction milieu shift species performance away from the niche optimum?, and 2) do species have a higher invasive potential if they have divergent trait values compared to the interaction milieu? We developed a model where a target species showing a given performance response curve to an environmental gradient, i.e., generalist or specialist, interacts with predators and competitors. The predictions of the model were compared with empirical findings on the abundance patterns of species along a salinity gradient in a green beach ecosystem. Green beaches are characterized by their strong gradients and spatial variability in abiotic factors, and their relatively simple food web consisting of Collembola species and their spider predators. First, our results showed that interaction milieu can displace species from their fundamental niche optimum. This led to abundance patterns that cannot be predicted by species performance response curves alone, emphasizing the importance to include ecological interactions. Second, species failed to invade their preferred part of the gradient if predators or competitors shared the target species' preference. Future studies should explore if the concept of interaction milieu can be generalized across trophic levels, and search for traits that are important on deciding the outcome of ecological interactions. Furthermore, the identification of the relevant response traits and their frequency distribution, in combination with trait plasticity of species in interaction milieus might be a step forward to link evolutionary principles to ecological networks, and vice versa.
