Impacts of harvesting on brine shrimp (Artemia franciscana) in Great Salt Lake, Utah, USA.
Selective harvesting can cause evolutionary responses in populations via shifts in phenotypic characteristics, especially those affecting life history. Brine shrimp (Artemia franciscana) cysts in Great Salt Lake (GSL), Utah, USA are commercially harvested with techniques that select against floating cysts. This selective pressure could cause evolutionary changes over time. Our objectives are to...
متن کاملBiostromes, brine flies, birds and the bioaccumulation of selenium in Great Salt Lake, ,Utah
Benthic organisms and substrates in Great Salt Lake, Utah, were sampled to measure selenium concentrations of prey organisms of the birds that utilize the lake for nesting and during migrations. The sampling was focused on stromatolite biostromes, as these solid reef-like structures cover approximately 23% of the oxic benthic area of the lake and are the principal habitat for brine fly (Ephydra...
متن کاملArthropod Evolution: Brine shrimp add salt to the stew
The expression patterns of homeotic genes in a crustacean-the brine shrimp Artemia franciscana-provide a new perspective on the evolution of arthropod body plans. The ancestral arthropod is thought to have had a body made up of a series of similar segments, each bearing an unspecialized limb. A major trend in arthropod evolution has been an ever-increasing specialization and regional-ization of...
متن کاملGreat Salt Lake Selenium Standard
The Great Salt Lake ecosystem is widely recognized to be unique and to have very high environmental and commercial value. Great Salt Lake is recognized regionally, nationally, and hemispherically for its extensive wetlands, and its tremendous and often unparalleled values to migratory birds. These values are derived from the lake’s unique physical features, including its immense size, dynamic w...
متن کاملA Bioeconomic Model of the Great Salt Lake Watershed
111 We present a computable general equilibrium model of the interface between the Great Salt Lake (GSL) ecosystem and the regional economy that impacts the ecosystem. With respect to the ecosystem, the model treats the various representative species as net-energy maximizers and bases population dynamics on the period-by-period sizes of surplus net energy. Energy markets-where predators and pre...
