Hazards of volcanic lakes: analysis of Lakes Quilotoa and Cuicocha, Ecuador
Volcanic lakes within calderas should be viewed as high-risk systems, and an intensive lake monitoring must be carried out to evaluate the hazard of potential limnic or phreatic-magmatic eruptions. In Ecuador, two caldera lakes – Lakes Quilotoa and Cuicocha, located in the high Andean region >3000 a.s.l. – have been the focus of these investigations. Both volcanoes are geologically young or his...

—Nitrogen (N) and phosphorus (P) cycling in lakes can be impacted by numerous abiotic and biotic factors. Large animals, such as birds and mammals, may recycle nutrients within a system or bring them in from surrounding habitats or different landscapes. Eared Grebes (Podiceps nigricollis) congregate in large numbers in the fall on the Great Salt Lake (GSL), Utah, and may have an important role ...
متن کاملMercury Concentrations in Fish-eating Birds from the Pinchi Lake Area in Relation to Productivity and Reproductive Success
Bald eagles and red-necked grebes were monitored from 2000 2002 on several lakes along the Pinchi fault, an area with a known source of geologic mercury and previous Hg mining (on Pinchi Lake), in an effort to discern whether increased Hg concentrations were affecting reproductive success and productivity. To determine whether or not Hg levels were elevated, fish tissues (rainbow trout and nort...
متن کاملLake Use by Three Avian Piscivores and Humans: Implications for Angler Perception and Conservation
Humans and colonial piscivorous birds are often perceived to be in conflict over shared aquatic habitats and fisheries resources in inland lakes. We examined angler perception of birds and the relative abundance of American white pelicans (Pelecanus erythrorhynchos), double-crested cormorants (Phalacrocorax auritus), western grebes (Aechmophorus occidentalis), and boats on two lakes in Saskatch...
