“…RID-LER, DENT, and ARRINGTON (2006) (STEWARD et al, 2006). Similarly, research on the response of fish communities to the 2004 storms showed an initial short-term impact but rapid recovery (PAPERNO et al, 2006;STEVENS, BLEWETT, and CASEY, 2006). The results of the present study indicate that the tropical storms of 2004 greatly accelerated the rates and magnitudes of change in salinity within Pellicer Creek, but the effects on the benthic plant or fish communities remain undocumented.…”

“…More common and generalist species in both areas, however, exhibited rapid recovery and some species even increased in abundance. While initial mortality is high from storm surges, due to turbulence and low dissolved oxygen, estuarine fishes are mostly resilient to saltwater storm surges and recover to preimpact conditions within 4-6 weeks (Hutchinson and Williams 2003;Paperno et al 2006;Stevens et al 2006). Freshwater fishes in the downstream reaches (e.g., centrarchids) also exhibited an ability to withstand storm surge impacts.…”

“…Increased amounts of leaf litter in aquatic systems can cause marked increases in nutrient inputs to these systems Schaefer et al 2000;Mallin et al 2002), which in turn, can lead to bottom water hypoxia (Paerl et al 2001). Because of the lack of preimpact data available, there have been few attempts to directly measure how these hurricane impacts affect fish assemblages (Paperno et al 2006;Stevens et al 2006).…”

Hurricane Katrina struck southeastern Louisiana on 29 August 2005 and thereby created an opportunity to examine the effects of a catastrophic storm on fish assemblages in a coastal stream. Bayou Lacombe is a small (46.1 river kilometers), primarily freshwater stream that drains into the northeastern portion of Lake Pontchartrain, a large oligohaline estuary located north of New Orleans. In summer 2005 (prior to the hurricane), three upstream and three downstream reaches of Bayou Lacombe were surveyed by electrofishing. These same six reaches were resurveyed in the summer of 2006 to assess the effects of the hurricane on fish assemblages. There were significant changes in fish assemblages at the downstream and upstream reaches. At the downstream reaches, centrarchid species such as bluegill Lepomis macrochirus, warmouth L. gulosus, and redspotted sunfish L. miniatus increased in abundance after the hurricane, as did inland silverside Menidia beryllina and striped mullet Mugil cephalus, both estuarine‐dependent species. At the upstream reaches, longear sunfish L. megalotis decreased after the hurricane and weed shiners Notropis texanus, goldstriped darters Etheostoma parvipinne, and warmouth were absent from posthurricane samples. Principal components and BEST analyses showed that differences in dissolved oxygen between years were related to fish assemblage changes in the upstream reaches. Salinity and temperature were associated with fish assemblage changes in the downstream reaches. Similar significant changes could occur in other coastal streams prone to increased hurricane activity.

“…Intensive work has been done on estuaries and benthic/demersal communities where the impact of hypoxia forces species to adapt quickly or perform avoidance migrations (Pihl et al, 1991;Keister et al, 2000;Renaud, 1986). The complete species inventory of a community may be substituted by hypoxiatolerant species from neighbouring habitats (Stevens et al, 2006). Evidence for the impact of low oxygen on pelagic communities in open coastal and offshore waters is scarce.…”

Impacts of hypoxia on the structure and processes in pelagic communities (zooplankton, macro-invertebrates and fish)

Abstract. Dissolved oxygen (DO) concentration in the water column is an environmental parameter that is crucial for the successful development of many pelagic organisms. Hypoxia tolerance and threshold values are species-and stagespecific and can vary enormously. While some fish species may suffer from oxygen values of less than 3 mL O 2 L −1 through impacted growth, development and behaviour, other organisms such as euphausiids may survive DO levels as low as 0.1 mL O 2 L −1 . A change in the average or the range of DO may have significant impacts on the survival of certain species and hence on the species composition in the ecosystem with consequent changes in trophic pathways and productivity.Evidence for the deleterious effects of oxygen depletion on pelagic species is scarce, particularly in terms of the effect of low oxygen on development, recruitment and patterns of migration and distribution. While planktonic organisms have to cope with variable DOs and exploit adaptive mechanisms, nektonic species may avoid areas of unfavourable DO and develop adapted migration strategies. Planktonic organisms may only be able to escape vertically, above or beneath the Oxygen Minimum Zone (OMZ). In shallow areas only the surface layer can serve as a refuge, but in deep waters many organisms have developed vertical migration strategies to use, pass through and cope with the OMZ.Correspondence to: W. Ekau (wekau@zmt-bremen.de) This paper elucidates the role of DO for different taxa in the pelagic realm and the consequences of low oxygen for foodweb structure and system productivity. We describe processes in two contrasting systems, the semi-enclosed Baltic Sea and the coastal upwelling system of the Benguela Current to demonstrate the consequences of increasing hypoxia on ecosystem functioning and services.
