The findings of a week-long survey of coastal marine molluscs around King Island are documented. In total, 408 species were recorded, 78 for the first time. King Island appears to be the only Tasmanian outpost for 44 species. Only two non-native species were found. A number of usually distinct species-pairs or groups appear to form intergrades around King Island. Along the island's east coast, beached shells belonging to Quaternary-era sub-fossils were found, not all of which are represented in the contemporary local fauna. Following critical examination of published sources and museum specimens, a checklist of King Island's coastal marine mollusc fauna is presented, comprising 619 species. It is likely that many more local species await discovery and documentation.
A pragmatic approach to the long-term monitoring of rivers leverages available information with targeted field investigations to address key uncertainties relevant to management decisions. An over-arching management issue for many rivers is how reservoir operation affects the amount and location of in-channel sediment and the resulting distribution of aquatic habitats. We integrate remotely acquired and field-survey morphologic data for the Cedar River, Washington, to constitute the current status of aquatic habitats and benchmarks for long-term monitoring that will inform streamflow management. Four key habitats (river edge, side channels, riffles, and pools) are feasible to monitor with high-resolution aerial imagery, a longitudinal profile of the river, and a side channel inventory, but full characterization of the functional differences within these habitats requires additional information. Habitat use information such as redd surveys will continue to be important for long-term monitoring where it cannot be inferred reliably from physical habitat characteristics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
