“…Multivariate analysis showed nematode assemblage composition in crab-tile plots to be comparable to controls after 36 h. The sampled intertidal mudflat meiofaunal communities can, therefore, be defined as resilient. This is supported by previous studies, which found meiofaunal recovery times from physical disturbance to vary between 12 h and 48 h, depending on habitat type (Sherman and Coull, 1980;Hockin, 1982;Mistri et al, 2004).…”

The provision of artificial shelters for the collection of crabs, known as crab-tiling, and the subsequent harvesting of the soft "peeler" crabs for angling bait, are associated with trampling disturbance of intertidal mudflats in the United Kingdom. Recovery of meiofauna communities following crab-tiling activity was investigated on an intertidal mudflat in SW England. Harvesting of experimental plots was reproduced six times over a 2-week period. Meiofauna was collected at low tides 12h, 36 h and 144 h after treatment. Meiofaunal and nematode abundance, and nematode species number, was significantly greater in controls compared to crab-tile stations at 12h. At 36 h and 144 h there were no significant differences between treatments, indicating recovery had occurred in 12-36 h. Multivariate analysis showed nematode assemblage composition from control plots to be significantly different from crab-tile plots at 12h. No significant differences were observed between sediment physical parameters with treatment. Results suggest that the predominant effect of disturbance may be vibration-induced burial, which causes nematodes to bury deeper into the sediment, beyond the depth sampled, and explains the rapid recovery.

“…The theory of island biogeography (MacArthur and Wilson, 1967) predicts decreasing species richness with increasing distance from source areas, even when there are habitat ‘stepping stones’ that diminish isolation (Wilson and Hunt, 1967). The effects of isolation from source areas have been demonstrated experimentally for a variety of marine species requiring ‘hard’ substrates, including fish and a variety of invertebrates (Schoener, 1974; Molles, 1978; Hockin, 1982; Osman and Dean, 1987). New field studies, focused on the western portions of the archipelago, are required to resolve the existence and locations of additional ecological transitions in the Aleutians.…”

This compilation of new information and summaries of earlier work emphasizes variability within marine waters of the Aleutian Archipelago. From the Alaska Peninsula to Near Strait, net flow through the passes is northward, with four passes (Amukta, Amchitka, Buldir, and Near Strait) contributing most of the flow. East of Samalga Pass (169°W), waters derived from the Alaska Coastal Current predominate, whereas west of Samalga Pass, waters of the Alaskan Stream predominate. The pattern of storm tracks creates a climatological (interannual and long term) transition zone in weather features (e.g. surface air temperature) near 170°W. The marine ecosystem of the Aleutian Archipelago also has a strong discontinuity at Samalga Pass, where cold‐water corals, zooplankton, fish, marine mammals and foraging seabirds show a step change in species composition. Diets of ground fish, Steller sea lions (Eumetopias jubatus) and some seabirds also change there. Lower growth rates of some fish species and stable isotope data indicate that productivity declines westward along the archipelago. The available data demonstrate considerable ecosystem variability over time scales of decades to millennia. Abrupt changes in composition of fish communities at several of the major passes suggest that Samalga Pass may mark only one of several ecological divisions of Aleutian waters. This spatial and temporal heterogeneity provides an important context within which to view recent declines in populations of Steller sea lions and other species, and has important implications for the management of regional marine resources. We conclude that the marine waters of the Aleutian Archipelago are divided into at least two different ecological regions, with potential for a concomitant separation of some fishery resources.

“…Therefore, lakes can also be perceived as islands within a sea of terrestrial landscapes (Keddy, 1976;Eadie et al, 1986;Minns, 1989;Heino, 2011), having also its own size, shape, diversity and history, as any other true island. Although lakes could serve as good models to study island biogeography theory, relatively few works have done so (but see e.g., Hubbard, 1973;Browne, 1981;Hockin, 1982;Brönmark, 1985;March and Bass, 1995;Harris et al, 2011;Brooks and Colburn, 2012). Most of the tests of island biogeography theory in lakes focus on the relationship between species richness and lake surface area and/or isolation (March and Bass, 1995;Rolon et al, 2008;Bagella et al, 2010;Bosiacka and Pieńkowski, 2011;Brooks and Colburn, 2012).…”
