Tidal creeks are widespread and abundant estuarine ecosystems, yet their ecological relevance is undervalued as reflected by the lack of research on these systems relative to larger, better-known estuarine systems (e.g. the Chesapeake Bay, the Albemarle–Pamlico Sound System, Florida Bay, to name a few). These better-known large estuaries contain numerous tidal creeks which, in comparison to the...

BACKGROUND Volatile organic compounds (VOCs) are human-made chemicals widely spread in the environment and produced by petrochemical industries and petroleum refineries. The aim of this research was to evaluate the distribution of VOCs in the ambient air of Mahshahr Petrochemical Complex, Iran. METHODS This study was a cross-sectional research performed in 2009. We used the method numbered 15...

Coastal salt marsh tidal creeks are thought to show less channel adjustment/movement relative to their terrestrial fluvial counterparts. We propose a mechanism for disturbance-mediated bank failure that may allow/initiate channel migration in these otherwise stable systems. The stability of tidal creeks is promoted by the extensive vegetation root structure along the banks. However, wrack mats ...

Fish associated with Australian saltmarshes have previously been sampled fi-om within creeks or semi-permanent pools on the marsh; this is the first record of fish use of marsh flats inundated on high tides but emergent on low tides. Buoyant pop nets (9 m^ 1 mm mesh) were used to collect fish from two areas of the marsh flat on Torrens Island in the Barker Inlet-Port River estuary. South Austra...

Lauren McConnell, Department of Earth Sciences, University of South Alabama, Mobile, AL 36688. E-mail: [email protected] Perch Creek and Alligator Bayou are tributaries to Dog River, both being similar in nature and close in proximity. The goal of this project is to determine whether Alligator Bayou contains a higher concentration of phosphorus and nitrates due to agricultural run-off...

Deviations in bilateral symmetry or fluctuating asymmetry of an organism may result under environmental stressors that reduce developmental homeostasis and stability. Anthropogenic stressors such as increased urbanization can negatively impact environmental quality of aquatic ecosystems. Researchers have stressed the value in finding easy, accurate and inexpensive methods for assessing potentia...

Expectations of ecological and fisheries benefits of habitat restoration are commonly used to justify its high financial cost; however, few empirical studies that rigorously test these expectations exist. Here, we describe the results of a study designed to quantify the effects of restoring oyster reefs in marsh tidal creeks on the mobile macrofauna. We used a before/after control/impact (BACI)...

Dendritic tidal creek networks are important habitats for sustaining biodiversity and ecosystem functioning in salt marsh wetlands. To evaluate the importance of creek heterogeneity in supporting benthic secondary production, we assess the spatial distribution and secondary production of a representative polychaete species (Dentinephtys glabra) in creek networks along a stream-order gradient in...

0-group sea bass, Dicentrarchus labrax, colonize intertidal marsh creeks of Mont Saint Michel Bay, France, on spring tides (e.g., 43% of the tides) during flood and return to coastal waters during ebb. Most arrived with empty stomachs (33%), and feed actively during their short stay in the creeks (from 1 to 2 h) where they consumed on average a minimum of 8% of their body weight. During flood t...
