The response of primary producers to nutrient enrichment in a shallow estuary The response of primary producers to nutrient enrichment in a shallow estuary

Shallow coastal systems worldwide are exhibiting increased algal growth in response to nutrient enrichment. This study evaluates primary production patterns in an estuarine system (Bass Harbor Marsh, Maine) receiving low levels of anthropogenic nitrogen. Biomass, areal coverage and in situ oxygen production of green macroalgae, Ruppia maritima, and phytoplankton were measured over a...

The Wisconsin Frog and Toad Survey: Update and 1984-97 trends [abstract] The Wisconsin Frog and Toad Survey: Update and 1984-97 trends [abstract]

The Wisconsin Frog and Toad Survey (WFTS) is a volunteer-based, roadside auditory count that began in 1981. It's protocols were recently modified for continent-wide use by the North American Amphibian Monitoring Plan (NAAMP). In 1997 we initiated a study to compare data collected by the WFTS and NAAMP protocols, in order to guide WFTS transition from its current methodology to one more...

Fish and wildlife species as sentinels of environmental endocrine disruption Fish and wildlife species as sentinels of environmental endocrine disruption

This chapter provides an overview of the history and criteria for use of captive and free-ranging fish and wildlife (amphibians, reptiles, birds, and mammals) species as sentinels of potential environmental endocrine disruption. Biochemical, behavioral, physiological, immunological, genetic, reproductive, developmental, and ecological correlates of endocrine disruption in these sentinels...

A survey of whitewater recreation impacts along five West Virginia rivers A survey of whitewater recreation impacts along five West Virginia rivers

Results are reported from an assessment of whitewater river recreation impacts at river accesses and recreation sites along five West Virginia rivers: the New, Gauley, Cheat, Tygart, and Shenandoah. Procedures were developed and applied to assess resource conditions on 24 river access roads, 68 river accesses, and 151 recreation sites. The majority of river accesses and recreation sites...

Evidence from Lake Baikal for Siberian glaciation during oxygen-isotope substage 5d Evidence from Lake Baikal for Siberian glaciation during oxygen-isotope substage 5d

The paleoclimatic record from bottom sediments of Lake Baikal (eastern Siberia) reveals new evidence for an abrupt and intense glaciation during the initial part of the last interglacial period (isotope substage 5d). This glaciation lasted about 12 000 yr from 117 000 to 105 000 yr BP according to correlation with the SPEC-MAP isotope chronology. Lithological and biogeochemical evidence...
