Larval settlement preference of a native bivalve: the influence of an invasive alga versus native substrata
Recruitment patterns of marine invertebrates are strongly influenced by the habitat preference of larvae as larvae can choose to settle (or not) in response to positive or negative cues. High abundances of recruits of the native infaunal bivalve Anadara trapezia occur in the invasive alga Caulerpa taxifolia compared to native habitats. Using controlled laboratory experiments, A. trapezia larval...
متن کاملDifferences in anti-predator traits of a native bivalve following invasion by a habitat-forming seaweed
Invasive habitat-forming species cause large changes to the abiotic environment, whichmay lead to lethal and sublethal effects on native fauna. In this study, we tested whether morphological anti-predator traits of an infaunal bivalve, Anadara trapezia, differed between areas invaded by the habitat-forming seaweed Caulerpa taxifolia and uninvaded habitats in estuaries in New South Wales, Austra...
متن کاملUranium in aragonitic marine bivalve shells
a r t i c l e i n f o Uranium concentrations in foraminiferal and coral skeletons track oceanic [CO 3 2 − ] and can be useful as a proxy of ocean acidification, but this pH proxy is yet to be investigated in bivalves. Two Saxidomus giganteus shells from the industrialized Puget Sound (WA, USA) and one from the more pristine Kodiak Island (AK, USA) were sampled through ontogeny for U/Ca using la...
متن کاملHabitat Simulation Technique as a Powerful Tool for Instream Flow Needs Assessment and River Ecosystem Management
Instream flow needs (IFN) assessment studies are performed to provide guidelines for stream water management and to assess the impacts of different water projects such as weirs, dams and stream diversions on the available fish habitat. The physical habitat simulation is one of the IFN assessment methods and also a powerful tool in management of river ecosystem that has not become a common metho...
متن کاملThe Bivalve Corbicula fluminalis (Müller, 1774): an Indicator for Heavy Metals Accumulation in the Habitat of Zayandeh-Roud River
The accumulation of the heavy metals Cd, Zn, Cu, and Pb were surveyed in the samples of mantle tissues, crusts and so the habitat sediments of C. fluminalis to reveal the probable biomonitoring rule of the bivalve in the ecosystem. The warm-cold seasonally samplings were carried out over the stations of Zayandeh-Roud River in Safi'eh, Isfahan province, during 2014. The warm and cold seasonal a...
