Bats of the piñon-juniper woodlands of southwestern Colorado Bats of the piñon-juniper woodlands of southwestern Colorado
As one of the most abundant and widespread forest types in the Southwest, piñon-juniper woodlands are used to varying degrees by many bat species (Chung-MacCoubrey 1996; Findley et al. 1975; Hoffmeister 1986; Jones 1965). Because of the uniqueness and rarity of old-growth piñon-juniper, the ancient woodlands of Mesa Verde Country likely provide bats with a combination of roosting and...

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...

Biological structure and dynamics of fish assemblages in tributaries of eastern Lake Ontario Biological structure and dynamics of fish assemblages in tributaries of eastern Lake Ontario
Interest in effective management of Great Lakes natural resources and restoration of native populations has stimulated interest in the conditions and ecological role of tributaries in the Great Lakes ecosystem. Rivers of Lake Ontario's eastern basin provide an excellent opportunity to examine important tributaries and their relationship to Lake Ontario. This paper reports on the results...

Brittle deformation along the Gulf of Alaska margin in response to Paleocene-Eocene triple junction migration Brittle deformation along the Gulf of Alaska margin in response to Paleocene-Eocene triple junction migration
A spreading center was subducted diachronously along a 2200 km segment of what is now the Gulf of Alaska margin between 61 and 50 Ma, and left in its wake near-trench intrusions and high-T, low-P metamorphic rocks. Gold-quartz veins and dikes, linked to ridge subduction by geochronological and relative timing evidence, provide a record of brittle deformation during and after passage of...

Changes in wetland sediment elevation following major storms: implications for estimating trends in relative sea-level rise Changes in wetland sediment elevation following major storms: implications for estimating trends in relative sea-level rise
Hurricanes can be important agents of geomorphic change in coastal marshes and mangrove forests. Hurricanes can cause large-scale redistribution of sediments within the coastal environment resulting in sedimentation, erosion, disruption of vegetated substrates, or some combination of these processes in coastal wetlands. It has been proposed that such sediment pulsing events are important...
