Can earthworms survive fire retardants? Can earthworms survive fire retardants?
Most common fire retardants are foams or are similar to common agricultural fertilizers, such as ammonium sulfate and ammonium phosphate. Although fire retardants are widely applied to soils, we lack basic information about their toxicities to soil organisms. We measured the toxicity of five fire retardants (Firetrol LCG-R, Firetrol GTS-R, Silv-Ex Foam Concentrate, Phos-chek D-75, and...

Age-specific survival and philopatry in three species of European ducks: A long-term study Age-specific survival and philopatry in three species of European ducks: A long-term study
Capture-recapture and band recovery models were used to estimate age-specific survival probabilities for female Northern Shovelers (Anas clypeata), Common Pochards (Aythya ferina), and Tufted Ducks (Aythya.fuligula) at Engure Marsh, Latvia, in 1964-1993. We banded more than 65,100 day-old ducklings of both sexes and captured 10,211 incubating females (3,713 new bandings and 6,498...

Flood magnitude and frequency of Monongahela Brook at the culvert on New Jersey Route 41, Deptford Township, Gloucester County, New Jersey Flood magnitude and frequency of Monongahela Brook at the culvert on New Jersey Route 41, Deptford Township, Gloucester County, New Jersey
Flood magnitude and frequency of Monongahela Brook in Deptford Township, Gloucester County, New Jersey, were determined by using the rational method. Flood-magnitude and -frequency estimates, as well as drainage-basin characteristics, are included in this report. The 100-year-flood estimate is 80 cubic feet per second.

Ultrastructure of the haemocytes of Ixodes scapularis (Acari: Ixodidae) Ultrastructure of the haemocytes of Ixodes scapularis (Acari: Ixodidae)
Haemocytes of Ixodes scapularis were characterized on the basis of their ultrastructure by transmission electron microscopy of thin sections. Three types of haemocytes were identified: prohaemocytes, plasmatocytes, and granulocytes. Prohaemocytes are undifferentiated cells containing very little cytoplasm (high nucelo-cytoplasmic ratio). Plasmatocytes are rich in free ribosomes...

Nutritional value of winter foods for whooping cranes Nutritional value of winter foods for whooping cranes
We measured metabolizable energy and digestibility of Whooping Crane (Grus americana) winter foods (blue crab [Callinectes sapidus]), common Rangia clam (Rangia cuneata), wolfberry fruit (Lycium carolinianurn [wolfberry]), and live oak acorn (Ouercus virginiana [acorn])] with feeding trials to captive-reared Whooping Cranes. Apparent metabolizable energy coefficients (expressed as %)...

Flood magnitude and frequency of Main Ditch at the culvert on New Jersey Route 44 and at the Conrail culvert downstream, West Deptford Township, Gloucester County, New Jersey Flood magnitude and frequency of Main Ditch at the culvert on New Jersey Route 44 and at the Conrail culvert downstream, West Deptford Township, Gloucester County, New Jersey
The magnitude and frequency of floods at Main Ditch at the culvert on New Jersey Route 44 at milepost 8.3 and at the Conrail culvert 0.21 miles downstream, in West Deptford Township, New Jersey, were determined by using the New Jersey Department of Environmental Protection Special Report 38 method. Flood-magnitude and -frequency estimates, as well as drainage-basin characteristics, are...

Ecology, Conservation, and Management of Colonial Waterbirds in the Mediterranean Region Ecology, Conservation, and Management of Colonial Waterbirds in the Mediterranean Region
(excerpt from Forword) The Mediterranean Symposium, part of the annual conference of The Colonial Waterbird Society in October 1993 in Arles, France, was the successful culmination of ideas shared among leading European waterbird and wetland scientists... Both invited and contributed papers focused on two areas - breeding biology (especially of threatened or little known species), and...
