“…Few studies have assessed dispersal unit survival (see e.g. Brochet et al ., ,b; Raulings et al ., ; Águas et al ., ; Banha & Anastácio, ; Banha et al ., ) (Table ), and such survival requires experimental validation and should not be assumed.

“…A combination of controlled laboratory and simulated bird flight experiments demonstrated greater probability of attachment to duck plumage than to duck feet, and the ability of C. pseudogracilis to remain attached and survive (10% probability) flight conditions for a distance of up to 6.8 km. Similarly, both Aguas et al (2014) and Anast acio et al (2014) examined the capability of waterbirdmediated external dispersal of recently hatched and juvenile, invasive red swamp crayfish respectively (see Table 1). Recently, hatched crayfish adhered and remained attached to the plumage of a slow moving (≤ 0.5 m s À1 ) mallard duck carcass during simulated swim conditions.…”

SUMMARY1. Aquatic birds can facilitate the dispersal of plants, animals, microbes and fungi. Here, we review existing literature on bird-mediated external (ectozoochorous; synonyms epizoochorous, exozoochorous) dispersal to determine the importance of birds as mobile links between aquatic environments, and to evaluate ectozoochory as a mechanism of dispersal for aquatic organisms and their propagules (collectively referred to as dispersal units). Bird-mediated ectozoochory occurs when dispersal units stick to feathers, feet and bills, become enmeshed within plumage or encapsulated within mud coating the soft parts of vector birds. 2. The importance of waterbird-mediated ectozoochorous dispersal relates to the topical problems of increasing anthropogenic habitat fragmentation, climate change and the associated alterations in species distributions and biological invasions. Nevertheless, some aspects of the bird-mediated ectozoochorous dispersal remain understudied, and poorly understood. 3. This review identifies two areas where further research is required. Firstly, the quantitative contribution of bird-mediated ectozoochory to overall dispersal remains unclear. Secondly, greater consideration of all the requirements necessary for successful waterbird-mediated ectozoochorous dispersal is needed. In particular, the impact of factors which influence attachment and detachment of dispersal units (e.g. dispersal unit densities, preening behaviour and the role of encapsulating mud) needs further examination. Moreover, few investigators have taken the step of examining viability of found dispersal units, and fewer still have examined tolerances of dispersal units to the 'in-flight' conditions experienced during transport, in order to determine probability of survival of external dispersal. 4. Evidence presented in this review indicates that bird-mediated ectozoochorous transport of aquatic dispersal units is a frequent process, at least at a local scale, and therefore needs to be considered in the context of connectivity and gene flow between isolated aquatic environments.

1. Despite their importance for aquatic biodiversity, ponds are among the most vulnerable freshwater habitats. Owing to their isolation in terrestrial environments, ponds are expected to be relatively well protected from biological invasions, but this depends on many factors.2. The purpose of this study was to examine the influence of a range of variables (water quality, habitat, and landscape attributes) on the colonization of discrete ponds by a widespread aquatic invader, the red swamp crayfish Procambarus clarkii, which can disperse overland.3. Investigations were conducted in two networks of ponds, each located in close proximity to a large invaded marsh. The two marshes under study differed in the length of time since the crayfish were introduced.4. The proportions of colonized ponds and crayfish abundances were moderate in both networks, but higher in the network that had been invaded first. In both networks the distance to the marsh was the main predictor of pond colonization, considering similar energy costs to cross aquatic and terrestrial habitats for the recently invaded network, but assuming that dispersal was 25 times costlier across the terrestrial matrix than via streams for the earlier invaded network. Pond characteristics had no influence on crayfish occurrence in either network. Furthermore, predictions of pond invasion were lower for the recently invaded network. 5. The importance of the distance to the marsh indicates that natural dispersal was the main process of pond colonization by crayfish. Findings also suggested that overland dispersal was rare and costly. By contrast, streams were probably significant in facilitating crayfish dispersal. Differences between the two networks might arise from an invasion process still in progress in the recently invaded network. 6. From a management viewpoint, local actions are encouraged to prevent the spread of crayfish via streams. In addition, broader-scale actions to mitigate other human disturbances would improve the outlook for pond biodiversity.
