Cranial and dental abnormalities of the endangered red wolf Canis rufus Cranial and dental abnormalities of the endangered red wolf Canis rufus
Three skulls of captive-raised female endangered red wolves (Canis rufus) exhibited severe malocclusion of the jaws. Cranial and dental abnormalities (including crowding of upper toothrows, and an extra tooth behind the lower left M3 in one of the three mandibles) were also evident. Ratios of alveolar length of maxillary toothrow to maximum width across the outer sides of crowns of P4...

Use of a helicopter to capture flighted cranes Use of a helicopter to capture flighted cranes
Using a helicopter, we pursued 12 sandhill cranes (Grus canadensis) and captured 6. In forested habitat, cranes could be forced down, but we were unable to deploy the pursuit team, so cranes could not be captured. In open habitat, every crane we pursued was captured. Target cranes were forced to the ground in 0.3-14 minutes. Adjusting pursuit distance (50-150 m) was essential in...

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...
