Presynaptic regulation of transmission at the first olfactory synapse was investigated by selectively imaging axon terminals of receptor neurons in the lobster olfactory lobe and turtle olfactory bulb. In both species, action potential propagation into axon terminals after olfactory nerve stimulation was measured using voltage-sensitive dyes. In addition, in the turtle, calcium influx into term...

Assessments of the conservation and fisheries effects of marine reserves typically focus on single reserves where sampling occurs over narrow spatiotemporal scales. A strategy for broadening the collection and interpretation of data is collaborative fisheries research (CFR). Here we report results of a CFR program formed in part to test whether reserves at the Santa Barbara Channel Islands, USA...

Lobster-ISS is an X-ray all-sky monitor experiment selected by ESA two years ago for a Phase A study (now almost completed) for a future flight (2009) aboard the Columbus Exposed Payload Facility of the International Space Station. The main instrument, based on MCP optics with Lobster-eye geometry, has an energy passband from 0.1 to 3.5 keV, an unprecedented daily sensitivity of 2×10 erg cm s, ...

In order to explore the functions of the peptide proctolin in the lobster nervous system, 3 classes of neurons showing proctolin-like immunocytochemical staining were selected for study. These neurons were identified on the basis of physiological and/or morphological criteria, isolated by dissections, and analyzed with biochemical methods to determine whether they contained authentic proctolin ...

Aspects of the feeding behaviour of Ergalatax contractus (Muricidae) were studied. Field experiments demonstrated that large numbers of individuals of this species, comprising *90% of a suite of gastropod scavengers, were attracted to baited traps in the subtidal sands of Lobster Bay, Cape d’Aguilar Marine Reserve, Hong Kong. Laboratory experiments identi¢ed the e¡ective chemo-detection distanc...

Over-exploited fisheries are a common feature of the modern world and a range of solutions including area closures (marine reserves; MRs), effort reduction, gear changes, ecosystem-based management, incentives and co-management have been suggested as techniques to rebuild over-fished populations. Historic accounts of lobster (Jasus frontalis) on the Chilean Juan Fernández Archipelago indicate a...

We studied the ecology of four species of coastal marine.homalopsine snakes (OrientalAustralian rear-fanged water snakes) in the Pasir Ris Park mangrove forest, Singapore, using survey methods and radiotelemetry. The snake assemblage atPasir Ris (220 snakes collected) was dominated by Cerberus rynchops (72.7% of total snakes), amedium-sized piscivore. Three species of crustacean eaters were als...

Salmonid aquaculture occurs in coastal Atlantic waters around the Canadian Maritimes and can overlap with American lobster ( Homarus americanus) fishery, most profitable fishery region. There has been debate whether there is potential for salmonid to negatively affect that heated both scientific community public news media. This review resultant commentary explore developing research approaches...

Abundance of juvenile lobsters at the new outfall site: comparisons with inshore abundances and discussion of potential impacts on lobster populations. The Massachusetts Water Resources Authority (MWRA) was mandated by the Outfall Monitoring Task Force (OMTF) to design and execute a study in the cobble-boulder habitats of the new outfall nearfield region for determination of the density of earl...
