“…Many of these taxa (species or genus level identification; see Table S4) were also found in our study, but with lower density in the east zone and in spring collections. We suggest that the most parsimonious ex planation of low occupancy by Gulf sturgeon of all sizes and the associated reduced macrobenthic densities in the eastern zone result from the coupling of minor physical habitat characteristic differences within the eastern estuary, industrialization, and sediment alteration (Lytle & Lytle 1985, Peterson et al 2007, Partyka & Peterson 2008, which have jointly degraded sediments and thus critical feeding habitat in the east zone compared to the west zone of the Pascagoula River estuary.…”

“…amphipods, isopods, and mollusks; e.g. Dauer 1993, Dean 2008) across the Pascagoula River estuary likely indicates overall pollution or sediment alteration (Lytle & Lytle 1985, Partyka & Peterson 2008. Total sediment hydro carbon content in Bayou Casotte, the Es ca tawpa River, and the industrialized east Pascagoula River distributary region of the Pascagoula River estuary ranged from 306 to 13 300 µg g −1 (Lytle & Lytle 1985); values in the west and east mouth, however, were about the same (12.9 versus 14.8 µg g −1 , respectively) as was % total organic carbon (TOC; 0.85 versus 0.86).…”

“…Partyka & Peterson (2008) noted that altered areas in the eastern distributary exhibited coarser sediments and greater %TOC than non-altered areas immediately up-estuary, and this pattern may explain the absence or low abundance of key fish diet components (Hargeria rapax and Corophium [= Apocorophium] loui si anum); thus, the east distributary has been viewed as having poor habitat quality for nekton. Engle et al (1994) indicated that tubificid and polychaete worms were useful indicators of organic pollution, and Lerberg et al (2000) noted that macrobenthic richness and diversity were significantly lower in impacted areas compared to non-impacted (control) salt marsh creeks, mainly driven by the lack of crustaceans and bivalves.…”

Gulf sturgeon Acipenser oxyrinchus desotoi is listed as 'threatened' under the US Endangered Species Act throughout its range in the northern Gulf of Mexico, with Mobile Bay, Alabama, USA, as the recognized break between eastern and western populations. Population recovery requires protection of the species and its critical habitat. We examined Gulf sturgeon physical habitat attributes and infaunal macrobenthic prey density and composition both spatially and seasonally relative to acoustically tagged Gulf sturgeon occurrence in the Pascagoula River estuary. Gulf sturgeon occupancy patterns indicated that adults move quickly through the system during fall and spring compared to longer but more spatially and temporally variable occupancy for juveniles and sub-adults in both seasons; sub-adults exhibited a less spatially and temporally variable occupancy pattern. We found significant differences in physical habitat and macrobenthic density characteristics that partially explained Gulf sturgeon spatial and temporal occupancy patterns. Direct comparisons of physical drivers (% silt, depth, particulate organic carbon) and macrobenthic density patterns (BEST procedures) were significantly correlated (p < 0.01) but weak (global R = 0.277) and suggest alternate hypotheses to better explain the differential estuarine habitat use patterns. The most parsimonious explanation with multiple weights-of-evidence suggests reduced use of the eastern distributary habitat by Gulf sturgeon based on synergistic effects of urbanization and industrialization such as bulkheading, channelization, dredging and related maintenance activities, and beach re-nourishment, all of which occur almost exclusively in the east zone of the estuary.

“…Given the regional focus on wetland habitat loss, it is easy to lose sight of the fact that most estuaries have a variety of habitats that exist in a mosaic [10] and that variations in the landscape such as habitat structure and abiotic factors that vary temporally and spatially [8,[11][12][13] provide a complex environment for associated mobile species. Physical/chemical properties of the estuarine waters of Barataria Bay vary along a north to south salinity gradient which is influenced by freshwater input, tides, and wind, and with water temperatures that varies seasonally, and three habitat types dominate estuaries in Louisiana: marsh (largely Spartina sp.…”

Louisiana wetlands are disappearing at a dramatic rate, providing an impetus for identifying the relative value to fishes of a matrix of estuarine habitat types. The distribution, relative abundance, biomass, and length of spotted seatrout, Cynoscion nebulosus (Cuvier) were examined in Barataria Bay, Louisiana, in relation to habitat type and abiotic variables. Spotted seatrout were collected from three sites located along a salinity gradient. Each site contained the three habitat types of interest: marsh edge, soft bottom and oyster shell, and were sampled monthly from May 2003 to May 2004 with gillnets. Habitat preference of spotted seatrout was not easily defined by habitat type alone, but rather their distribution, relative abundance, biomass and length distribution were influenced by a combination of habitat type and abiotic variables. These results suggest that habitat type and abiotic properties of the water act together to provide a diverse range of available habitats important to spotted seatrout. Despite the importance of incorporating habitat in fisheries management, it may be that a combination of habitats and their spatial arrangement, as well as abiotic variables, contribute to the value of estuarine habitats in support of fisheries productivity. Thus, efforts to ensure future fisheries productivity of spotted seatrout fisheries in Louisiana will likely be maximized by managing the spatial integrity of multiple habitat types as opposed to focusing on any single type.

“…Considerable research has been carried out in coastal wetland science studies. This has included elaboration of land use and land cover (LULC) and vegetation community maps (Wright and Gallant, 2007), analysis of hydrological and land cover changes in wetlands, using high-resolution Quickbird satellite imagery to distinguish and map black mangroves (Everitt et al, 2008), using habitat suitability mapping in Chongming Dongtan NR, China (Tian et al, 2008), determining habitat patch connectivity and corridors in refuge design (Partyka and Peterson, 2008), assessing coastline changes (Ekercin, 2007;Vidal and Filograsso, 2008), determining the effects of habitat loss and species diversity on landscape composition (Cardozo and Chiaraviglio, 2008;La Greiner, Reams, and Mendelssohn, 2000;Simenstad et al, 2006), and pursuing biodiversity conservation, eradication of poverty, and coastal management (Foster et al, 2007).…”

Journal of Coastal Research, 27(5), 966-972. West Palm Beach (Florida), ISSN 0749-0208.Habitat change of coastal wetlands caused by natural and anthropogenic factors is an important issue facing China. Large areas of coastal habitat are disappearing, and those remaining become vulnerable to anthropogenic impacts from industry, agriculture, aquaculture, urban development, and domestic waste. A question is whether the change of habitat area has an influence on boundary adjustments of natural reserves. The study reported in this paper applied remotesensing images, and environmental and socioeconomic data to analyse the change of land use and land cover and habitat quality in an estuarine area and to identify the driving forces for these changes from
