Pattern and pathways for mercury lifespan bioaccumulation in Carcinus maenas.

Cadmium bioaccumulates after acute exposure but has no effect on locomotion or shelter-seeking behaviour in the invasive green shore crab (Carcinus maenas)

Cadmium (Cd2+) is a non-essential metal ubiquitous in the environment due to industrial processes. However, little is known regarding the ability of Cd2+ to impact the behaviour of aquatic animals in receiving environments. Green shore crabs (Carcinus maenas) were exposed to waterborne Cd2+ [control (no Cd2+), low (0.30 μmol/L), medium (3.3 μmol/L) and high (63 μmol/L)], for 24 h, then, crabs w...

Trophic and direct transfer of microplastics into the common shore crab Carcinus maenas. ICES CM 2013/A:02

Microscopic plastic debris is emerging as a global conservation issue. Ingestion of microplastics has been demonstrated in a range of marine animals both in the laboratory and in the oceans, but we know little of how microplastics may be transferred across trophic levels. Here, we used mussels (Mytilus edulis) and crabs (Carcinus maenas) to investigate the bioaccumulation and trophic transfer o...

Experimental evidence for latent developmental plasticity: intertidal whelks respond to a native but not an introduced predator.

Animals with highly inducible traits may show no inducible response when exposed to a related but wholly novel cue. This appears to be true for the intertidal whelk Nucella lamellosa faced with a voracious introduced predator. In the laboratory, we exposed whelks to effluent from two species of predatory crab, the native red rock crab Cancer productus and the invasive European green crab Carcin...

Range extension of two invasive crab species in eastern Australia: Carcinus maenas (Linnaeus) and Pyromaia tuberculata (Lockington).

Relatively few introduced crabs are presently known from Australian waters. The present report significantly extends the documented range of the European Shore Crab Carcinus maenas (Linnaeus) and the Fire Crab Pyromaia tuberculata (Lockington) in eastern Australia, based on recently collected specimens now deposited in the Australian museum, Sydney (AM), and old collections in the Macleay museu...
