Trace elements in soil and biota in confined disposal facilities for dredged material Trace elements in soil and biota in confined disposal facilities for dredged material
We studied the relation of trace element concentrations in soil to those in house mice (Mus musculus), common reed (Phragmites australis) and ladybugs (Coccinella septempunctata) at five disposal facilities for dredged material. The sites had a wide range of soil trace element concentrations, acid soils and a depauperate fauna. They were very poor wildlife habitat because they were...

[Book review] Return of the Whooping Crane [Book review] Return of the Whooping Crane
Fewer than 40 years ago, Life magazine ran an article decrying the plight of Whooping Cranes (Grus americana) on their wintering grounds at Aransas National Wildlife Refuge (Aransas) along the Gulf Coast. The small flock of approximately 20 birds that summered at Wood Buffalo National Park (Wood Buffalo) in Canada and wintered on the Texas coast at Aransas comprised the entire wild...

Environmental contaminant concentrations in biota from the lower Savannah River, Georgia and South Carolina Environmental contaminant concentrations in biota from the lower Savannah River, Georgia and South Carolina
Planned harbor expansion and industrial developments may adversely affect the economically important aquatic resources of the lower Savannah River, including those at the Savannah National Wildlife Refuge. To establish the present level of chemical contamination in this system, we collected a total of 102 samples of nine species of fish and fiddler crabs (Uca pugilator) from eleven sites...

Brain cholinesterase inhibition in songbirds from pecan groves sprayed with phosaline and disulfoton Brain cholinesterase inhibition in songbirds from pecan groves sprayed with phosaline and disulfoton
Brain cholinesterase (ChE) activities of songbirds collected in pecan groves 6 to 7 hr after separate applications of the organophosphorus pesticides, phosalone and disulfoton, were compared to mean ChE activities of controls (normals) as a measure of insecticide exposure. In general, reduction of brain ChE activity ≥2 standard deviations below the control mean indicates exposure to an

Statistical inference for capture-recapture experiments Statistical inference for capture-recapture experiments
This monograph presents a detailed, practical exposition on the design, analysis, and interpretation of capture-recapture studies. The Lincoln-Petersen model (Chapter 2) and the closed population models (Chapter 3) are presented only briefly because these models have been covered in detail elsewhere. The Jolly- Seber open population model, which is central to the monograph, is covered in...

Owls Owls
Eight species of owls regularly occur and may breed in one or more of the southeastern states. Several additional northern or western species appear irregularly as accidentals or during years of southward incursions. In the Southeast, the most common and wide- spread owls are the common barn-owl, eastern screech-owl, great horned owl and barred owl; the most restricted is the burrowing...

Breeding biology of the spotted salamander Ambystoma maculatum (Shaw) in acidic temporary ponds at Cape Cod, USA Breeding biology of the spotted salamander Ambystoma maculatum (Shaw) in acidic temporary ponds at Cape Cod, USA
The relationship between water chemistry and breeding success of spotted salamanders Ambystoma maculatum (Shaw) was examined in temporary woodland ponds on outer Cape Cod, Massachusetts in 1985 and 1986. Most pond waters were dilute (3median coductivity = 57 umhos cm−1 (1 umhos cm−1 = 0·1 mSm−1)), acidic (median pH = 4·82), and highly colored (median = 140 Pt-Co units). Most acidity was...
