In contrast, most people would consider a natural enemy used against a marine pest, such as the
green crab, to be unsafe if it were to significantly reduce Dungeness crab populations, even if the natural enemy was effective against the targeted pest.
Further, with increased salinity and benthic abundance and diversity, conditions are now more hospitable to a new assemblage of predators [e.g., Atlantic horseshoe crabs (Limulus polyphemus), American eels (Anguilla rostrata), moonsnails (Euspira heros), and invasive species, including the invasive European
green crab (Carcinus maenas)].
Weight-carapace width relationship of the Mediterranean
green crab (Carcinus aestuarii, Nardo 1847) in Cakalburnu Lagoon, Izmir Bay.
Similarly, because of strong tidal mixing through the Gulf and San Juan Islands and in Admiralty Inlet, temperatures of surface waters in the Strait are typically less than 10[degrees]C, too cold for
green crab larvae to develop (deRivera et al.
Grosholz of the University of New Hampshire in Durham has shown that the
green crab has culled 90 percent of the small shore crabs (Hemigrapsus oregonensis) and native clams (Nutricola).
Another [in a netted plot (4.2-mm aperture) without cultured clams] was a European
green crab Carcinus maenas (9.18 mm).
Ultrastructural changes in the gill epithelium of
green crab Carcinus maenas in relation to external salinity.
One of the most globally abundant crabs is the invasive
green crab Carcinus maenas (Linnaeus), which is a prominent and ecologically important inhabitant of rocky shores and mudflats in the northwest Atlantic.
A carbonic anhydrase repressor is localized in the sinus gland of the eyestalk in the euryhaline
green crab, Carcinus maenas.
In contrast, the European
green crab has long been recognized as a menace to marine systems (SN: 6/13/98, p.
Because of the phenomenon of El Nino, the Davidson Current was very strong in 1997, the year that the
green crab was first discovered in Oregon.
ABSTRACT The physiology of ion regulation in the highly invasive European
green crab Carcinus maenas has been widely studied, but mostly in constant salinity conditions, and not in context of their molt cycle-dependent sternite coloration.
