Metal concentrations in aquatic macrophytes as influenced by soil and acidification Metal concentrations in aquatic macrophytes as influenced by soil and acidification
Bioavailability of metals to aquatic plants is dependent on many factors including ambient metal concentration, pH of soil or water, concentration of ligands, competition with other metals for binding sites, and mode of exposure. Plants may be exposed to metals through water, air, or soil, depending on growth form. This paper examines the influence of soil type under two regimens of...

Demography of forest birds in Panama: How do transients affect estimates of survival rates? Demography of forest birds in Panama: How do transients affect estimates of survival rates?
Estimates of annual survival rates for a multispecies sample of neotropical birds from Panama have proven controversial. Traditionally, tropical birds were thought to have high survival rates for their size, but analyses by Kart et al. (1990. Am. Nat. 136:277-91) contradicted that view, suggesting tropical birds may not have systematically high survival rates. A persistent criticism of...

International impact research and management International impact research and management
To be sustainable, ecotourism requires the protection of natural environments and processes both from development and operation of the tourism infrastructure, and from the activities of ecotourists within protected areas. This book chapter reviews the international literature on the study of visitor or recreation-related resource impacts with special reference to ecotourism. Four case...

Effects of pesticides on Canada Geese Effects of pesticides on Canada Geese
This paper summarizes published and unpublished sources relating to exposure of Canada geese (Branta canadensis) to pesticides, emphasizing documented episodes of poisoning by organochlorine (OC), organophosphorus (OP), and carbamate compounds. Canada geese accumulate the lipid-soluble OC compounds, although they have a lower potential for biomagnification of these pesticides than...

Copper hazards to fish, wildlife and invertebrates: a synoptic review Copper hazards to fish, wildlife and invertebrates: a synoptic review
Selective review and synthesis of the technical literature on copper and copper salts in the environment and their effects primarily on fishes, birds, mammals, terrestrial and aquatic invertebrates, and other natural resources. The subtopics include copper sources and uses; chemical and biochemical properties; concentrations of copper in field collections of abiotic materials and living...
