Evaluating the power to detect temporal trends in fishery independent surveys: A case study based on Gillnets Set in the Ohio waters of Lake Erie for walleye Evaluating the power to detect temporal trends in fishery independent surveys: A case study based on Gillnets Set in the Ohio waters of Lake Erie for walleye
Fishery-independent (FI) surveys provide critical information used for the sustainable management and conservation of fish populations. Because fisheries management often requires the effects of management actions to be evaluated and detected within a relatively short time frame, it is important that research be directed toward FI survey evaluation, especially with respect to the ability...

Fledging success is a poor indicator of the effects of bird blow flies on ovenbird survival Fledging success is a poor indicator of the effects of bird blow flies on ovenbird survival
Infestations of bird blow flies (Protocalliphora spp. and Trypocalliphora braueri) have various negative effects on the condition of nestling birds. In the absence of other stressors such as inclement weather, however, infestation alone rarely reduces fledging success. Previous studies have documented effects of blow flies on nestling condition and fledging success. Without information...

Warmwater and coldwater fish in two-story stranding waters Warmwater and coldwater fish in two-story stranding waters
Two-story fisheries occur in lakes or reservoirs characterized by two distinct spatial strata, warmwater and coldwater. These strata develop as the system begins to warm in the spring or summer in response to solar radiation and then separate into an upper warmwater stratum (epilimnion, hereafter referred to as the upper stratum) and a lower coldwater stratum (hypolimnion, hereafter...

An introduction to standardized sampling An introduction to standardized sampling
It was probably one of the oddest riots in the history of the United States. In Erie, Pennsylvania during 1853. federal marshals were called to restore order during bloody uprisings. A mob of women, equipped with sledgehammers, was tearing up railroad rack to protest standardization of track width (Nesmith 1985). All across the United States, standardization of rail gauges was talking...

Movement and habitat use of sika and white-tailed deer on Assateague Island National Seashore, Maryland Movement and habitat use of sika and white-tailed deer on Assateague Island National Seashore, Maryland
This research project was conducted to describe habitat use of sika deer (Cervus nippon) and white-tailed deer (Odocoileus virginianus) and possibly attribute the effects of ungulate herbivory to specific deer species, if spatial separation in habitat use could be identified. Sturm (2007) conducted an exclosure study to document the effect of feral horse (Equus caballus) herbivory, deer...

Influences of high-flow events on a stream channel altered by construction of a highway bridge: A case study Influences of high-flow events on a stream channel altered by construction of a highway bridge: A case study
Impacts of highway construction on streams in the central Appalachians are a growing concern as new roads are created to promote tourism and economic development in the area. Alterations to the streambed of a first-order stream, Sauerkraut Run, Hardy County, WV, during construction of a highway overpass included placement and removal of a temporary culvert, straightening and regrading of...

Warmwater fish in wadeable streams Warmwater fish in wadeable streams
Both “warmwater” and “wadeable” are terms of convenience without precise definition and are used by biologists to describe streams that are generally too warm to have sustainable salmonid populations and can be safely traversed by walking (i.e., a section of stream should have the majority of its length less than 1 m deep, and it should be possible to cross in chest waders in nearly all...

Effects of landscape gradients on wetland vegetation communities: information for large-scale restoration Effects of landscape gradients on wetland vegetation communities: information for large-scale restoration
Projects of the scope of the restoration of the Florida Everglades require substantial information regarding ecological mechanisms, and these are often poorly understood. We provide critical base knowledge for Everglades restoration by characterizing the existing vegetation communities of an Everglades remnant, describing how present and historic hydrology affect wetland vegetation...

Rivers and streams: Physical setting and adapted biota Rivers and streams: Physical setting and adapted biota
Streams and rivers are enormously important, with their ecological, and economic value, greatly outweighing their significance on the landscape. Lotic ecology began in Europe with a focus on the distribution, abundance, and taxonomic composition of aquatic organisms and in North American with a focus on fishery biology. Since 1980, stream/river research has been highly interdisciplinary...

Short-term response of methane fluxes and methanogen activity to water table and soil warming manipulations in an Alaskan peatland Short-term response of methane fluxes and methanogen activity to water table and soil warming manipulations in an Alaskan peatland
Growing season CH4 fluxes were monitored over a two year period following the start of ecosystem-scale manipulations of water table position and surface soil temperatures in a moderate rich fen in interior Alaska. The largest CH4 fluxes occurred in plots that received both flooding (raised water table position) and soil warming, while the lowest fluxes occurred in unwarmed plots in the...
