High-elevation observations of Long-tailed Weasel and Eastern Chipmunk in North Carolina High-elevation observations of Long-tailed Weasel and Eastern Chipmunk in North Carolina

Observations of Mustela frenata (Long-tailed Weasel) are rare within the southern Appalachians, while observations of Tamias striatus (Eastern Chipmunk) are uncommon in high-elevation spruce-fir forests. We conducted camera-trap surveys at Roan Mountain Highlands, Mitchell County, NC, during summer 2016 in a Picea rubens (Red Spruce)—Abies fraseri (Fraser Fir) forest. During the survey...

Fish assemblages Fish assemblages

Methods to sample fishes in stream ecosystems and to analyze the raw data, focusing primarily on assemblage-level (all fish species combined) analyses, are presented in this chapter. We begin with guidance on sample site selection, permitting for fish collection, and information-gathering steps to be completed prior to conducting fieldwork. Basic sampling methods (visual surveying...

Fisheries and aquatic resources of Prairie Creek, Redwood National Park Fisheries and aquatic resources of Prairie Creek, Redwood National Park

This report synthesizes information on the status of fisheries and aquatic resources in the Prairie Creek sub-basin of Redwood Creek in Humboldt County in northern California, founded on a bibliographic search we conducted of historic and current datasets, unpublished reports, theses, and publications. The compiled Prairie Creek Fisheries Bibliography is available at https://irma.nps.gov...

Considerations in representing human individuals in social ecological models Considerations in representing human individuals in social ecological models

In this chapter we focus on how to integrate the human individual into social-ecological systems analysis, and how to improve research on individual thought and action regarding the environment by locating it within the broader social-ecological context. We discuss three key questions as considerations for future research: (1) is human thought conceptualized as a dynamic and adaptive...

A global analysis of traits predicting species sensitivity to habitat fragmentation A global analysis of traits predicting species sensitivity to habitat fragmentation

Aim Elucidating patterns in species responses to habitat fragmentation is an important focus of ecology and conservation, but studies are often geographically restricted, taxonomically narrow or use indirect measures of species vulnerability. We investigated predictors of species presence after fragmentation using data from studies around the world that included all four terrestrial...

Beaver colony density trends on the Chequamegon-Nicolet National Forest, 1987 – 2013 Beaver colony density trends on the Chequamegon-Nicolet National Forest, 1987 – 2013

The North American beaver (Castor canadensis) is a managed species in the United States. In northern Wisconsin, as part of the state-wide beaver management program, the Chequamegon-Nicolet National Forest removes beavers from targeted trout streams on U.S. Forest Service lands. However, the success of this management program has not been evaluated. Targeted removals comprise only 3% of...

Determination of habitat requirements for Apache Trout Determination of habitat requirements for Apache Trout

The Apache Trout Oncorhynchus apache, a salmonid endemic to east-central Arizona, is currently listed as threatened under the U.S. Endangered Species Act. Establishing and maintaining recovery streams for Apache Trout and other endemic species requires determination of their specific habitat requirements. We built upon previous studies of Apache Trout habitat by defining both stream...

Conservation Reserve Program mitigates grassland loss in the lesser prairie-chicken range of Kansas Conservation Reserve Program mitigates grassland loss in the lesser prairie-chicken range of Kansas

Since the beginning of the 20th century, the overall occupied range of the lesser prairie-chicken (Tympanuchus pallidicinctus) has declined by 84% commensurate with population trends. Much of this decline has been attributed to the loss and fragmentation of native grasslands throughout the lesser prairie-chicken range. However, quantification of changes in land cover in the distribution...

An evaluation and comparison of conservation guidelines for an at-risk migratory songbird An evaluation and comparison of conservation guidelines for an at-risk migratory songbird

For at-risk wildlife species, it is important to consider conservation within the process of adaptive management. Golden-winged Warblers (Vermivora chrysoptera) are Neotropical migratory songbirds that are experiencing long-term population declines due in part to the loss of early-successional nesting habitat. Recently-developed Golden-winged Warbler habitat management guidelines are...

Validation of daily increments periodicity in otoliths of spotted gar Validation of daily increments periodicity in otoliths of spotted gar

Accurate age and growth information is essential in successful management of fish populations and for understanding early life history. We validated daily increment deposition, including the timing of first ring formation, for spotted gar (Lepisosteus oculatus) through 127 days post hatch. Fry were produced from hatchery-spawned specimens, and up to 10 individuals per week were...
