The use of aquatic macrophytes in monitoring and in assessment of biological integrity The use of aquatic macrophytes in monitoring and in assessment of biological integrity
Aquatic plant species, populations, and communities should be used as indicators of the aquatic environment, allowing detection of ecosystem response to different stressors. Plant tissues bioaccumulate and concentrate toxin levels higher than what is present in the sediments; and this appears to be related to organic matter content, acidification, and buffering capacity. The majority of...

Toward the use of remote sensing and other data to delineate functional types in terrestrial and aquatic systems Toward the use of remote sensing and other data to delineate functional types in terrestrial and aquatic systems
This chapter discusses the role that remotely sensed data play in improving the ability to document the distribution of global land cover types. If the relationships between the cover types and trace gas fluxes can be determined, then the dynamics of these fluxes can be established. The chapter discusses important aquatic systems—such as wetlands—and the land–water interface. Researchers...

Vocalization behavior and response of black rails Vocalization behavior and response of black rails
We measured the vocal responses and movements of radio-tagged black rails (Laterallus jamaicensis) (n = 43, 26 males, 17 females) to playback of vocalizations at 2 sites in Florida during the breeding seasons of 1992-95. We used regression coefficients from logistic regression equations to model the probability of a response conditional to the birds' sex, nesting status, distance to...

Wetlands of the Prairie Pothole Region: Invertebrate species composition, ecology, and management Wetlands of the Prairie Pothole Region: Invertebrate species composition, ecology, and management
The Prairie Pothole Region (PPR) of the United States and Canada is a unique area where shallow depressions created by the scouring action of Pleistocene glaciation interact with mid-continental climate variations to create and maintain a variety of wetland classes. These wetlands possess unique environmental and biotic characteristics that add to the overall regional diversity and...
