Down Effects of a Native Crab on a System of Native and Introduced Prey Emilyw
OPENQ ACCESS Freely available online e pLOSl- Preference Alters Consumptive Effects of Predators: Top- Down Effects of a Native Crab on a System of Native and Introduced Prey EmilyW. Grason"'', BenjaminG. Miner"' 1 WesternWashington University, Biology Department, Bellingham, Washington, United States of America,zshannon Point MarineCenter, Anacortes, Washington, UnitedStates of America Abstract Top-down effects of predators in systems depend on the rate at which predators consume prey, and on predator preferences among available prey. In invaded communities, these parameters might be difficult to predict because ecological relationships are typically evolutionarily novel. We examined feeding rates and preferences of a crab native to the Pacific Northwest, Cancer productus, among four prey items: two invasive species of oyster drill the marine whelks Urosaipinx cinerea and Ocenebra inornata! and two species of oyster Crassostrea gigas and Ostrea iurida! that are also consumed by U. cinerea and O. inornata. This system is also characterized by intraguild predation because crabs are predators of drills and compete with them for prey oysters!. When only the oysters were offered, crabs did not express a preferenceand consumedapproximately 9 juvenileoysters crab " day ". Wethen testedwhether crabs preferred adult drills of either U. cinerea or O. inornata, or juvenile oysters C. gigas!. While crabs consumed drills and oysters at approximately the same rate when only one type of prey was offered, they expressed a strong preference for juvenile oysters over drills when they were allowed to choose among the three prey items. This preference for oysters might negate the positive indirect effects that crabs have on oysters by crabs consuming drills trophic cascade! because crabs have a large negative direct effect on oysters when crabs, oysters, and drills co-occur. -

New Records for the Distribution and a Description of the Egg Capsules Of
New records for the distribution and a description of the egg capsules of the Japanese nassa, Hima fratercula (Dunker, 1860) Family Nassariidae in Ladysmith Harbour, B.C. 1 2 2 by R.M. Harbo , George P. Holm and W. (Bill) Merilees 1 Research Associate, Invertebrate Zoology, Royal BC Museum. E-mail: [email protected] 2, 3 Pacific Northwest Shell Club SUMMARY The intertidal Japanese snail, Hima fratercula (Dunker, 1860), was most likely introduced to Washington and B.C. from Japan along with Pacific oyster seed, Crassostrea gigas, over the period from the 1920’s to 1960’s. Previously, it has only been reported from isolated sites in Washington and at Boundary Bay, B.C. Both the native Western lean nassa, H.mendica and the non-native Japanese nassa, H. fratercula were found at numerous sites at the head of Ladysmith Harbour, B.C. over the period April to October, 2014. Bubble-shaped or bulliform egg capsules of H. fratercula, with 4 to 7 eggs per capsule, were found in May and June, 2014 at Ladysmith. H. fratercula were common and abundant in the mud under rocks, shells and wood debris. The limited distribution of the non-native species, H. fratercula at isolated sites may be attributed to a limited dispersal of crawl-away larvae. In contrast, the widely distributed native species, H. mendica has 28 to 33 embryos per capsule and planktonic larvae. ---------------------------------------------------------------------------------------------------------- It was a clear, sunny spring day in April, 2014. We slowly grounded the boat on the mud bottom at Page Point in Ladysmith Harbour, B.C. -

Risk assessment is the management approach or framework of choice in many disciplines, including health care and research, engineering design, and particularly the insurance sector which relies on the best available forward projections of natural hazards and accidents. The marine manage- ment community, which includes researchers, practitioners, and resource managers responsible for individual targeted stocks, aquaculture activ- ities, and the marine environment in general, has been slower to take up quantitative risk assessment approaches. Whilst there are prominent examples where risk assessment and management approaches have been applied, they are relatively few. This article theme set presents examples of such and identifies tools and approaches that can be applied to coastal and oceanic marine systems worldwide. The methods developed and the lessons learned from these studies can be used to guide researchers, practitioners, and resource managers. -

Species description Species name Rapana venosa, (Valenciennes, 1846) – Veined rapa whelk Synonyms Purpura venosa Valenciennes, 1846; Rapana thomasiana Crosse, 1861; ?Rapana marginata (Valenciennes, 1846); ?Rapana pechiliensis Grabau & King, 1928; Rapana pontica Nordsieck, 1969. Common names Veined rapa whelk, Asian rapa whelk (USA, UK); Thomas’ whelk (English common name for Black Sea whelks identified as R. thomasiana); Cocozza, Bobolone (IT); Geaderde stekelhoorn (NL); Bai top shell (commercial name for Bulgarian Black Sea specimens); Akanishi (JP). Taxonomic note The genus Rapana is sometimes referred to the family Muricidae (e.g., DAISIE, 2006), sometimes to Thaididae (e.g., Koutsoubas & Voultsiadou-Koukoura, 1991; Mann & Harding, 2000). According to World Register of Marine Species (WoRMS) the family should be Muricidae, and the Thaididae is considered a synonym of Rapaninae, a subfamily of Muricidae (see Bouchet & Rocroi, 2005). Identification Rapana venosa is a large, 9-16 cm shell length, species with a heavy, strongly sculptured shell. Specimens up to 17.5 cm have been recorded in the Black Sea (Micu et al., 2008). The spire is relatively short, less than half the height of the aperture. -
