Toxicological significance of soil ingestion by wild and domestic animals Toxicological significance of soil ingestion by wild and domestic animals
Most wild and domestic animals ingest some soil or sediment, and some species may routinely, or under special circumstances, ingest considerable amounts. Ingested soil supplies nutrients, exposes animals to parasites and pathogens, and may play a role in developing immune systems.1 Soil ingestion is also sometimes the principal route of exposure to various environmental contaminants.2-7...

Interaction between perchlorate and iodine in the metamorphosis of Hyla versicolor Interaction between perchlorate and iodine in the metamorphosis of Hyla versicolor
Perchlorate (ClO4-) is a water-soluble, inorganic anion that is often combined with ammonium, potassium or other cations for use in industry and agriculture. Ammonium perchlorate, for example, is a potent oxidizer and is used in various military applications including rocket fuel. It has also been found in an historically widely used fertilizer, Chilean nitrate and in other fertilizers...

Synergy of agroforestry and bottomland hardwood afforestation Synergy of agroforestry and bottomland hardwood afforestation
Afforestation of bottomland hardwood forests has historically emphasized planting heavy-seeded tree species such as oak (Quercus spp.) and pecan (Caryaillinoensis) with little or no silvicultural management during stand development. Slow growth of these tree species, herbivory, competing vegetation, and limited seed dispersal, often result in restored sites that are slow to develop...

Multiple stressor effects in relation to declining amphibian populations Multiple stressor effects in relation to declining amphibian populations
Original research discusses the protocols and approaches to studying the effects of multiple environmental stressors on amphibian populations and gives new perspectives on this complicated subject. This new publication integrates a variety of stressors that can act in concert and may ultimately cause a decline in amphibian populations. Sixteen peer-reviewed papers cover: Toxicity...
Bioindicators of contaminant exposure and effect in aquatic and terrestrial monitoring Bioindicators of contaminant exposure and effect in aquatic and terrestrial monitoring
Bioindicators of contaminant exposure presently used in environmental monitoring arc discussed. Some have been extensively field-validated and arc already in routine application. Included are (1) inhibition of brain or blood cholinesterase by anticholinesterase pesticides, (2) induction of hepatic microsomal cytochromes P450 by chemicals such as PAHs and PCBs, (3) reproductive problems...

Camping impact management on the Appalachian National Scenic Trail Camping impact management on the Appalachian National Scenic Trail
This report addresses the management of overnight use and associated impacts along the Appalachian National Scenic Trail (A.T.). This effort was initiated in response to agency and Appalachian Trail Conference (ATC) management concerns regarding the resource and social impacts of increasing overnight visitation, particularly in high use areas. Report findings and recommendations are...

Amphibian decline: An integrated analysis of multiple stressor effects Amphibian decline: An integrated analysis of multiple stressor effects
Capturing the attention and imagination of the public and the scientific community alike, the mysterious decline in amphibian populations drew scientists and resource managers from ecotoxicology and chemistry, ecology and field biology, conservation biology, and natural resource policy to a SETAC–Johnson Foundation workshop. Facilitating environmental stewardship, increasing capacity of...
