In nature, marine mussels (Mytilus edulis) suffer less fouling colonization on the newly formed sides of their shells. Using settlement assays with algal spores of Porphyra suborbiculata, we determined that spore attachment and germination on the periostracum decreased to 36.8 and 3.3 %, respectively. Additionally, the spore settlement was considerably diminished by periostracum dichloromethane...

The social complexion of Toronto’s urban landscape has been irreversibly altered since the 1960s as new waves of migrants from Africa, Asia, the Caribbean, and Central and South America have replaced traditional white European migrant flows. We examine the very different residential settlement patterns of Toronto’s three largest racial minorities – Blacks, Chinese and South Asians. Unlike previ...

Mortality patterns from peak of settlement to d~spersal from the nursery area, concurrently with integration of juveniles into adult populations, of 3 llttoral fishes of the genus Diplodus (D. puntazzo. D. sargus, and D. vulgaris) (Family Spalidae) were studied between May 1993 and June 1996. Twenty-one stations were censused weekly, weather conditions permitting, along the Mediterranean coasts...

We introduce a dynamic model in which the ability of agents to perform certain welfare improving transactions is subject to random and unobservable shocks. We characterize the optimal setup for incentive compatible transactions, the optimal payment system. Implementation involves assigning balances to individual agents and optimally adjusting these balances given the agents’ histories of transa...

Under a real-time gross settlement (RTGS) system, there is an incentive for system participants to delay making their outgoing payments to facilitate their funding, and this creates the risk of settlement delays spreading throughout the entire system. Intraday credit facility and market practices have been established to avoid the risk and led to settlement concentration in the morning, as well...

Ecology Letters (2012) 15: 338-346 ABSTRACT: Successful recruitment in shallow reef ecosystems often involves specific cues that connect planktonic invertebrate larvae with particular crustose coralline algae (CCA) during settlement. While ocean acidification (OA) can reduce larval settlement and the abundance of CCA, the impact of OA on the interactions between planktonic larvae and their pref...

Vibrated stone columns are frequently used as a method of reinforcing soft ground as they provide increased bearing capacity and reduce foundation settlements. Their performance in relation to bearing capacity is well documented, but there is also a need for enhanced understanding of their settlement characteristics, particularly in relation to small-group configurations. This paper presents re...
