| Fisheries-dependent Sami communities in the Norwegian Arctic face major challenges adapting and responding to social-ecological changes. On a local scale, communities and households continually adapt and respond to interacting changes in natural conditions and governance frameworks. Degradation of the marine environment and decline in coastal settlements can move social-ecological systems beyond critical thresholds or tipping points, where the system irreversibly enters a different state. We examined the recent social-ecological history of 2 fjords in Finnmark, North Norway, which have coped, over the past 30 years, with the collapse of local fish stocks, harp seal (Pagophilus groenlandicus) and red king crab (Paralithodes camtschaticus) invasions, and... |

| Several species of crabs from hydrothermal vent sites in the Pacific Ocean Were found to be infested by small, symbiotic nemertean worms. Worms occurred on both male and female crabs, and were located in mucous sheaths adhering to the axillae between the limbs of males and females, the setae of the pleopods of females, and the sterna of infested male and female crabs. Only juvenile and regressed adult worms were observed, primarily because no ovigerous hosts were examined. Similar species of worms mature by eating eggs, then regress or die after host eclosion. Based on the size of the worms from file vent crabs, their habitus with their crustacean hosts, the presence of accessory stylet pouches, and the presence of a single stylet on a large basis... |
