Lethal Dietary Toxicities of Environmental Contaminants and Pesticides to Coturnix Lethal Dietary Toxicities of Environmental Contaminants and Pesticides to Coturnix
Five-day subacute dietary toxicity tests of 193 potential environmental contaminants, pesticides, organic solvents, and various adjuvants are presented for young coturnix (Japanese quail, Coturnix japonica Temminck and Schlegel). The report provides the most comprehensive data base available for avian subacute dietary toxicity tests and is primarily intended for use in ranking toxicities...

Aquatic birds and selenium in the San Joaquin Valley Aquatic birds and selenium in the San Joaquin Valley
Kesterton Reservoir is a series of ponds comprising 1,200 acres sitting in the grasslands of the Kesterton National Wildlife Refuge. It is bounded on the east by the San Luis Drain, a concrete-lined canal that discharges agricultural drainage into the ponds at their southern end, from which point it then flows northward through the twelve ponds (see the map on the page following). Mike...

Subspecies of the greater scaup and their names Subspecies of the greater scaup and their names
The name Fuligula mariloides Vigors, presently used by many authors for a subspecies of the Greater Scaup, Aythya marila, was originally proposed for the Lesser Scaup, A. afinis, and may not be used in combination with the name marila. The name mariloides has been applied to a population of Greater Scaup in Kamchatka and the Commander Islands, supposedly distinguished by small size and...

Seasonal influence of nutrients on the physiology and behavior of captive canvasbacks (Aythya valisineria) Seasonal influence of nutrients on the physiology and behavior of captive canvasbacks (Aythya valisineria)
Captive canvasbacks (Aythya valisineria) were maintained ad libitum on five diets during the winters of 1978-79 and 1979-80 to evaluate the effects of varying protein and energy levels on feed intake and condition. Diets were formulated to simulate either a natural diet high in invertebrates or one high in vegetation. Two diets low in protein and energy simulated stress diets. Feed...

Toxicity of methyl parathion to bats: Mortality and coordination loss Toxicity of methyl parathion to bats: Mortality and coordination loss
The 24-h oral LD50 of methyl parathion (phosphorothioic acid O, O-dimethyl O-(4-nitrophenyl) ester) to little brown bats (Myotis lucifugus) (372 mg/kg) was 8.5 times the LD50 for mice (Mus musculus) (44 mg/kg). However, orally dosed mice either died or appeared behaviorally normal after 2 to 3 h, whereas many dosed bats, although alive at 24 h, could not right themselves when placed on...

Frozen gene pools - A future for species otherwise destined for extinction Frozen gene pools - A future for species otherwise destined for extinction
Conclusion: Semen banks and ova and embryo banks can be practical methods to maintain gene pools. Gene pool preservation is desperately needed today due to the rapid decline in number of species and their habitat, a matter that is of concern to.biologists, economists, and politicians worldwide. Techniques are available for the cryopreservation of semen from many animals (and embryos from...
