Visitor reponse to demonstration fees at National Wildlife Refuges Visitor reponse to demonstration fees at National Wildlife Refuges

In response to a request from the United States Fish and Wildlife Service, we examined the likelihood of visitors changing their plans for future visits to National Wildlife Refuges (NWR) because of changes in entrance or use fees. We obtained data for this study from 3,173 respondents from 14 NWRs between 1998 and 2000. Overall, only 8% of all respondents reported potential displacement...

USFWS demonstration fees USFWS demonstration fees

This study examined National Wildlife Refuge (NWR) visitors' reactions to changes in fees implemented as part of the fee demonstration program. Visitors' evaluations of the fees paid were examined in addition to their beliefs about fees and the fee demonstration program, and the impact of fees paid on their intention to return. All results were analyzed relative to socio-demographic

Assessing vulnerability to invasion by nonnative plant species at multiple spatial scales Assessing vulnerability to invasion by nonnative plant species at multiple spatial scales

Basic information on where nonnative plant species have successfully invaded is lacking. We assessed the vulnerability of 22 vegetation types (25 sets of four plots in nine study areas) to nonnative plant invasions in the north–central United States. In general, habitats with high native species richness were more heavily invaded than species-poor habitats, low-elevation areas were more...

Evaluation of a habitat suitability index model Evaluation of a habitat suitability index model

We assisted with development of a model for maternity habitat of the Indiana bat (Myotis soda/is), for use in conducting assessments of projects potentially impacting this endangered species. We started with an existing model, modified that model in a workshop, and evaluated the revised model, using data previously collected by others. Our analyses showed that higher indices of habitat...

Phylogeography and history of giant Galápagos tortoises Phylogeography and history of giant Galápagos tortoises

We examined the phylogeography and history of giant Galápagos tortoise populations based on mitochondrial DNA sequence data from 161 individuals from 21 sampling sites representing the 11 currently recognized extant taxa. Molecular clock and geological considerations indicate a founding of the monophyletic Galápagos lineage around 2–3 million years ago, which would allow for all the

Razorback sucker movements and habitat use in the San Juan River inflow, Lake Powell, Utah, 1995-1997 Razorback sucker movements and habitat use in the San Juan River inflow, Lake Powell, Utah, 1995-1997

Seventeen subadult, hatchery-reared razorback suckers (Xyrauchen texanus; (x̄ = 456 mm total length) were implanted with sonic transmitters and tracked for 23 months in the lower 89.6 km of the San Juan River (San Juan arm of Lake Powell, Utah). Fish were released at 2 sites, and 9 made extensive up-and downstream movements (x = 47.8 km; contact was lost with 4, and 4 others presumably...

Quality of life on the Colorado Plateau: a report to the respondents in southwestern Colorado and northwestern New Mexico Quality of life on the Colorado Plateau: a report to the respondents in southwestern Colorado and northwestern New Mexico

During the fall of 1998, scientists from the Midcontinent Ecological Science Center (MESC) of the U.S. Geological Survey (USGS) a?? sent a survey by mail to residents in southwest Colorado and northwest New Mexico to better understand quality of life issues in this area of the Colorado Plateau. Collaborators in this study included the Bureau of Land Management and U.S. Forest Service...

Examination of native fish recruitment and description of the fish communities found in the San Juan and Colorado River interface zones of Lake Powell, Utah Examination of native fish recruitment and description of the fish communities found in the San Juan and Colorado River interface zones of Lake Powell, Utah

Researchers examined the fish communities of the Colorado and San Juan river interface zones of Lake Powell during 1999 and 2000. The objectives were to: (1) search for young razorback sucker and Colorado pikeminnow and, if found, RIT tag them; (2) examine the effectiveness of the various collection techniques on juvenile native fish; and (3) describe the fish communities found in these
