“…This finding influences our perception of the distances over which gene flow and population rescue can occur (Keister et al 1982, Burke et al 1995, and perhaps our FIG. The longest dispersal from 2004 to 2007 was ;2 km, but by examining capture-recapture histories spanning back .20 years to 1983, we detected dispersal events nearly three times as far that linked the two wetland systems.…”

Inter-wetland connectivity, defined here as the movement of biota among discrete water bodies, can have important population- and community-level consequences in aquatic systems. We examined inter-wetland connectivity in a southeastern Australian national park by intensively monitoring the movements of freshwater turtles (Chelodina longicollis) via capture-mark-recapture over a three-year period, and more sporadically for 25 years. A high percentage (33%) of turtles moved between wetlands, suggesting that single wetlands should not represent the minimum habitat unit harboring a C. longicollis population. Distance was the only structural landscape metric correlated with inter-patch transition probability, with probability declining as inter-wetland distance increased. Movements also appear to be strongly influenced by shifting resource quality gradients between temporary wetlands and permanent lakes according to drought and flood cycles, a pattern more consistent with migration between critical resource patches than occasional interpopulational dispersal. Rare dispersal events of up to 5.2 km were known to occur. Captures at a terrestrial drift fence suggest that small and immature turtles moved between wetlands more frequently than our aquatic sampling indicated. We caution that measures of actual (or functional) connectivity can be biased by sampling methods and the temporal scale of sampling and must also be interpreted in the context of factors that motivate animal movements. This requires some understanding of spatial and temporal variation in intra-patch processes (e.g., quality and extent) and the expected movement responses of animals (e.g., habitat selection) over extended time frames, information that can potentially yield more important insight on connectivity than measures of landscape structural features alone.

“…-If HWA is a large central population, then no genetic differences would be found between individuals in different locations. Radiotracking and mark-recapture studies may not detect migrants and transients between the subpopulations, and gene flow could be maintained by matings between individuals within the subpopulations and transients (Kiester et al 1982) and/or consecutive matings across overlapping home ranges between Mallard Pools and Greencastle. The latter conclusion is supported by the knowledge of unmarked turtles found between the 2 subpopulations (Bernstein and Black, unpubl.…”

“…A relatively low level of gene flow may be required in long-lived organisms, such as turtles, to counteract genetic costs associated with population isolation (Kiester et al, 1982;Scribner et al, 1984). Additionally, our data suggest that the probability of detecting successful dispersal may be low because large scale movements are infrequent (Fig.…”
