Powdered and pelletized wollastonite (CaSiO3) was applied to an 11.8 ha forested watershed at the Hubbard Brook Experimental Forest (HBEF) in northern New Hampshire, U.S.A. during October of 1999. The dissolution of wollastonite was studied using watershed solute mass balances, and a Sr/ Sr isotopic tracer. The wollastonite (Sr/Sr = 0.70554) that was deposited directly into the stream channel b...

The Longdong Stream Salamander Batrachuperus londongensis, living in a mountain stream environment at Mt. Emei in Sichuan Province, China, represents a rare species that is facultatively neotenic in the family Hynobiidae. Although the species has been known to science for some 40 years since its initial discovery in the late 1970s, anatomical details of its osteology remain poorly understood an...

Most salmonid taxa have an anadromous life history strategy, whereby fish migrate to saltwater habitats for a growth period before returning to freshwater habitats for spawning. Moreover, several species are characterized by different life history tactics whereby resident and anadromous forms may occur in genetically differentiated populations within a same species, as well as polymorphism with...

In this study, the adult population of Otsego Lake walleye was estimated in order to evaluate the success of the walleye stocking program. Spawning walleye were trap netted at five locations in April 2008, marked with a dorsal fin punch and visible implant elastomer, and recaptured in May using boat electro-fishing and in September by NYSDEC experimental gill net survey. Catch per unit effort a...

-Batrachuperus mustersi occurs only in the Paghman Mountains of Afghanistan in a single stream. They inhabit the cold sources of the stream where they are active year-round, feeding on aquatic organisms. Morphological examination revealed many similarities to other members of the genus. Differences were found in the tail morphology, degree of skeletal ossification and gill development. The only...
