“…If the intermediate disturbance effect were responsible (Connell 1978, Petraitis et al 1989, one would expect species diversity to be higher in the M treatments; but neither H' nor richness differed significantly as a function of treatment (Table 3). Laine (2003) concluded that declining richness due to low DO stress in the Baltic Sea may make that system more vulnerable to invasion, but richness alone did not correlate with invasion success in the present experiment.…”

“…Few experiments, however, have tried to isolate the changes directly attributable to low DO vs. other correlated physical properties. In addition, more studies have focused on the effects of hypoxia on recruitment (Breitburg 1992, Sagasti et al 2000, 2003 and on single species tolerance (Sagasti et al 2001, Gray et al 2002 without considering the effects on the entire community (Llanso 1992). The question of how single species tolerances scale-up to community change is less clear.…”

Hypoxia is increasing in marine and estuarine systems worldwide, primarily due to anthropogenic causes. Periodic hypoxia represents a pulse disturbance, with the potential to restructure estuarine biotic communities. We chose the shallow, epifaunal community in the lower Chesapeake Bay, Virginia, USA, to test the hypothesis that low dissolved oxygen (DO) (< 4 mg l -1 ) affects community dynamics by reducing the cover of spatial dominants, creating space both for less dominant native species and for invasive species. Settling panels were deployed at shallow depths in spring 2000 and 2001 at Gloucester Point, Virginia, and were manipulated every 2 wk from late June to mid-August. Manipulation involved exposing epifaunal communities to varying levels of DO for up to 24 h followed by redeployment in the York River. Exposure to low DO affected both species composition (presence or absence) and the abundance of the organisms present. Community dominance shifted away from barnacles as level of hypoxia increased. Barnacles were important spatial dominants which reduced species diversity when locally abundant. The cover of Hydroides dianthus, a native serpulid polychaete, doubled when exposed to periodic hypoxia. Increased H. dianthus cover may indicate whether a local region has experienced periodic, local DO depletion and thus provide an indicator of poor water-quality conditions. In 2001, the combined cover of the invasive and cryptogenic species in this community, Botryllus schlosseri (tunicate), Molgula manhattensis (tunicate), Ficopomatus enigmaticus (polychaete) and Diadumene lineata (anemone), was highest on the plates exposed to moderately low DO (2 mg l -1 < DO < 4 mg l -1 ). All 4 of these species are now found worldwide and exhibit life histories well adapted for establishment in foreign habitats. Low DO events may enhance success of invasive species, which further stress marine and estuarine ecosystems.

“…There is a small number of rare species in the Baltic, and the prevalence of common, tolerant species makes the system more stable and resistant to environmental stress, e.g. warming, eutrophication (Bonsdorff and Pearson 1999, Gray 2002, Laine 2003, Boero and Bonsdorff 2007.…”

Extensive sampling (450 grabs) was performed all over the inner part of Puck Bay (105 km 2 area) in summers of [2007][2008][2009]. The GIS-based analysis of samples was performed to assess in detail the distribution of 32 benthic species. The minimum area of occurrence was less than 1 km 2 for Lekanosphaera rugicauda and the maximum was 83 km 2 for Cerastoderma glaucum. The material reveals that species with the pelagic larval stage were most widespread, with the least distance between individuals and the highest average density (e.g. Cerastoderma glaucum, Hydrobia ventrosa). The most isolated and the least dense species within the studied area were discretely mobile, non-larval crustaceans (e.g. Gammarus oceanicus and Lekanosphaera rugicauda), present at single sites with the largest distance from each other. We conclude that * Corresponding author e-mail: weslaw@iopan.gda.pl analysis of species distribution helps in understanding the threats to populations of marine invertebrates and marine spatial planning, through locating the isolated species and populations.
