“…The high diversity in Farakeh could be attributed to river flow with nutrients load that was in agreement with earlier reports (Saraladevi et al, 1996;Dittmann 2000;Desroy et al, 2002;Ingole et al, 2008), the high diversity in Asaluyeh it could be related to habitat heterogeneity. Sediment mixed up with fine and coarse particles tend to harbour more diverse assemblages than the sand or silt-clay alone, because they can host greater habitat diversity (Yu et al, 2006).…”

“…The low abundance of macrobenthic community in the Farakeh creek (Table 2) could be attributed to the Helleh river run off that carries heavy load of sediments. Sediment load of rivers has also been blamed for the low abundance of macrobenthos in the northern creeks of Bushehr (Mirdar et al, 2009) and other parts of the world (Dittmann, 2000;Spruzen et al, 2008). Moreover, the macrobenthic assemblage in Farakeh was characterized by a higher abundance of some brackish water species, namely brackish oligochaetes, which was similar to Mogias and Kevrekidis (2005).…”

The spatial distribution of the macrobenthic community was studied along the Iranian coasts of Bushehr province during January and February 2013. Samples were collected with van Veen grab from intertidal (0 m) and subtidal (5 m and 10 m depths) zones at 16 stations designated in 6 transects, including 4 main harbors (Genaveh, Bandargah, Rostami and Asaluyeh) and 2 creeks (Farakeh and Shif). A total of 17 groups (taxa) of macrobenthos were identified, of which the most dominant assemblages belonged to Mollusca, Annelida and Arthropoda. Abundance and biomass are significantly higher in some stations and depths than others, which could be correlated with combination of factors. The average macrofaunal abundance and biomass ranged from 450 to 4380 indm -2 and its from 9 to 165 gm -2 , respectively. The highest abundance and biomass were observed at 10 m and intertidal depths, respectively.

“…Sharks use intertidal mudflats where there is an abundance of prey, especially fat innkeeper worms, but not mudflats that have a relatively depauperate prey field relative to neighboring subtidal habitats. Mudflats that experience more variable and extreme environmental conditions, such as high intertidal mudflats or mudflats in the upper region of the slough, generally harbor fewer prey items (Beukema 1976, Dittmann 2000, Wasson et al 2002 and are less frequently utilized by leopard sharks. It also appears that the size of low intertidal mudflats is important, with large areas of continuous mudflats being better shark habitat than narrow bands bordering subtidal areas.…”

Bays and estuaries play important roles in the life history of leopard sharks Triakis semifasciata, yet these coastal environments are among those most impacted by human activity. To better understand habitat use, spatial associations, and ecological roles of leopard sharks in estuarine environments, movements of leopard sharks were studied in Elkhorn Slough, California, USA. A total of 21 female leopard sharks (78 to 140 cm total length) were tagged with acoustic transmitters and tracked from August 2003 to February 2005. Eight sharks were manually tracked for 20 to 71.5 h, and 13 sharks were monitored for 4 to 280 d using an array of acoustic receivers. Female leopard sharks exhibited a high degree of fidelity to Elkhorn Slough. The distribution of tagged sharks changed seasonally and was likely associated with changes in temperature, salinity, and dissolved oxygen. Sharks used the area that comprises Elkhorn Slough National Estuarine Research Reserve (ESNERR) extensively throughout the year, but especially during spring and summer. When sharks occupied ESNERR, their habitat use was tidally influenced, with sharks using low intertidal mudflats extensively when available. Sharks using the main channel tended to remain in subtidal habitats at all tidal levels. These results suggest that efforts to protect important leopard shark habitats in bays and estuaries should focus on preserving and restoring intertidal mudflats.

The influence of seasonal and ontogenetic changes on the dietary composition of 3 amphipod species (Synchelidium lenorostralum, S. trioostegitum and Gitanopsis japonica) were studied in the surf zone of a sandy shore habitat in Dolsando, southern Korea. The 2 species of Synchelidium were found to be carnivorous feeders, consuming mainly benthic harpacticoid copepods, whereas G. japonica had a diet consisting of both copepods and detritus. The dietary composition of S. lenorostralum and S. trioostegitum overlapped for all ontogenetic stages. Little overlap was found in the dietary composition of G. japonica compared with the 2 Synchelidium species, a characteristic that might favor the co-existence of the 3 species. S. lenorostralum displayed significant differences in dietary composition between sexes, among developmental stages, and over the seasonal cycle. For S. trioostegitum, dietary composition varied over the seasonal cycle. Juveniles of Synchelidium fed mainly on copepod nauplii and nematodes as well as on benthic harpacticoid copepods. Our results suggest that the biological interactions between benthic amphipods and meiofauna, such as benthic harpacticoid copepods and nematodes, may be important in the trophic chain of sandy shore surf zone habitats.KEY WORDS: Synchelidium lenorostralum · S. trioostegitum · Gitanopsis japonica · Amphipoda · Feeding · Sandy surf zone Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 258: [189][190][191][192][193][194][195][196][197][198][199] 2003 sandy shore habitats, often dominating benthic macrofaunal communities in terms of both numbers and biomass (Fenchel et al. 1975, Wijnsma et al. 1999, Dittmann 2000.

Amphipods play an important role in surf zone food webs, acting as a trophic link from primary producers to higher-order consumers. Clearly, quantitative assessments of trophic relationships between amphipods and their prey/predators are important for our understanding of energy flow in sandy shore surf zone environments (Gerdol & Hughes 1994).Various aspects of amphipod feeding activity have been studied, including diet (Fenchel et al. 1975, Biernbaum 1979, Nielsen & Kofoed 1982, Icely & Nott 1985, Stuart et al. 1985, diel feeding patterns (SainteMarie 1986, Gerdol & Hughes 1994, Ingolfsson & Agnarsson 1999) and the influence of food quality on growth and reproduction (Gee 1988, Johnson & Wiederholm 1989, Delong et al. 1993, Pöckl 1995, Poltermann 2000. These studies have provided basic information on the feeding ecology of freshwater and marine amphipods inhabiting sublittoral and intertidal habitats. However, there is no information available on the feeding characteristics of amphipods in sandy shore surf zone habitats.In the s...
