Subject:
Gobiidae; community structure; drought; estuaries; fish; freshwater; larvae; marine ecosystems; rivers; temporal variation; Australia
Abstract:
... Estuaries are transition zones that link freshwater and marine ecosystems and are often used as nursery areas by fish. The Murray–Darling Basin, which is heavily affected by flow regulation and water extraction, is the largest river system in Australia and terminates at the Murray Mouth estuary. Protracted drought conditions resulted in extremely low flows to the Murray Mouth that affected water c ...

Melicertus latisulcatus; Penaeus; abdomen; animals; biomass; body length; fisheries; fisheries management; food availability; larvae; larval development; rearing; salinity; spawning; temperature; South Australia
Abstract:
... Temperature, salinity and food availability are generally considered to have the most influence on larval growth and survival in penaeid species. Larval size has previously been used as a measure of animal quality in a range of crustacean species. The aim of this project was to investigate the effects of temperature (17°C, 20°C, 22.5°C and 25°C) on stage-specific larval size in Penaeus latisulcatu ...

Subject:
Eleotridae; fauna; taxonomic revisions; allozymes; mitochondrial DNA; phylogeny; freshwater fish; rain; biodiversity; case studies; biogeography; prediction; Australia
Abstract:
... As the driest inhabitable continent, it comes as no surprise that Australia has comparatively few species of freshwater-dependent fishes compared with land masses of similar size and latitudinal coverage. In addition to relatively low rainfall and few permanent waterbodies, a range of other climatic, geological, physical, and biogeographical factors are generally offered up, to account for the low ...

Abstract:
... Invasive algae alter the structure and function of ecosystems. The green alga Caulerpa taxifolia is an invasive alga introduced in the Mediterranean Sea, whereas Caulerpa prolifera is a native species in Mediterranean waters. The aim of the current work was to determine the oxidative status of both Caulerpa species by means of biomarker measures as a possible indicator of the regression state of C ...

Abstract:
... The encroachment of agriculture and human population is placing increasing levels of stress on estuarine ecosystems worldwide. The catchment of the Seteni Estuary, a small temporarily open/closed estuary in South Africa, has been under extensive sugar cultivation for over 60 years. The present study reports on the impact of agricultural practices on the structure and dynamics of its pelagic commun ...

Abstract:
... There is a lack of studies on how provisioning may influence shark numbers and behaviour. The effects of long-term provisioning were investigated at a Red Sea reef, where both grey reef shark (Carcharhinus amblyrhynchos) and silky shark (Carcharhinus falciformis) occurred. Initially, grey reef sharks outnumbered silky sharks, but over 6 years, silky shark numbers increased almost 20-fold, whereas ...

Abstract:
... The present study focuses on variations in day and night copepod community structure in a meromictic Mediterranean ecosystem (Lake Faro). Because of the high salinity in the lake, this environment is defined as a coastal-marine rather than true-lagoon ecosystem. Copepod abundances showed wide oscillations, with marked spatial and seasonal heterogeneity. The copepod assemblage was dominated by coas ...

Abstract:
... The stocking of predators can have significant consequences on recipient aquatic ecosystems. We investigated some potential ecological impacts of stocking a predatory fish (Lates calcarifer) into a coastal river and a large impoundment in north-eastern Australia. L. calcarifer was mostly found in slower-moving, larger reaches of the river or in the main body of the impoundment where there was abun ...

Abstract:
... Inadequate life-history information can compromise management of shark populations. The present study examined the life history of blacktip reef sharks (Carcharhinus melanopterus) from north-eastern Australia with predictions that they would show life-history patterns similar to those of other reef sharks species. Age and growth estimates were derived from vertebrae and five growth models. Males w ...
