What Can Birds Hear?, Robert C. Beason

United States Department of Agriculture Wildlife Services: Staff Publications

For bids, hearing is second in importance only to vision for monitoring the world around them. ./\vim hearing is most sensitive to sounds from about 1 to 4 kHz, although they can hear higher and lower frequencies. No species of bird has shown sensitivity to ultrasonic frequencies (>20 kHz). Sensitivity to frequencies below 20 Hz (dasound) has not received much attention; however, pigeons and a few other species have shown behavioral and physiological responses to these low frequencies. In general, frequency discrimination in birds is only about one-half or one-third as good it is for humans within the 1 …

Lower Grand River Watershed Management Plan, Fishbeck, Thompson, Car & Huber, Inc.

Watershed Management Plans and Reports

A Watershed Management Plan (WMP) considers many aspects of water usage and functions, and coordinates them into a comprehensive plan for managing the activities that govern how our natural resources are utilized or viewed. A WMP is developed to provide direction and prioritize how resources are used for the management, protection, or restoration of a watershed. A watershed approach is ideal for managing water resources since they cross jurisdictions and political boundaries. Often this fluid nature of water is overlooked or taken for granted. Water flows over the ground and picks up pollutants before reaching a lake, stream, wetland, or …

Toxicity Of Manufactured Particulate Materials On Plant Root Growth, Ling Yang

Dissertations

The rapid development of particle technology and the growing use of particulate materials in industries are bringing large amounts of manufactured particles into the environment. Epidemiological studies suggest that fine particles (particles with aerodynamic diameter smaller than 2.5 μm, i.e., PM_2.5) have an association with various adverse health effects in humans. Mass studies have been performed on the toxicity and toxicological mechanisms of airborne particles such as PM_2.5 and PM₁₀, but there are very few investigations which contribute to the knowledge base on biological implications of manufactured particulate materials. Up to now, the published toxicity …

The E!Ect Of Trap Spacing On The Capture Of Brown Tree Snakes On Guam, Richard M. Engeman, Michael A. Linnell

United States Department of Agriculture Wildlife Services: Staff Publications

Trapping is central to the integrated control program to deter brown tree snakes from entering the outbound cargo 1ow from Guam. Trapping brown tree snakes is effective, but labor intensive. Increasing inter-trap spacings without loss of e3cacy could substantially increase the e3ciency of efforts to prevent dispersal of this species. Inter-trap spacings of 20, 30 and 40 m along perimeter trap lines were compared using recaptures of tagged brown tree snakes. No differences were found among the different spacing distances for the distribution of recapture times. The results indicate that for some situations, snake trapping may be extended or made …

Ex Post Economic Analysis Of Reproduction-Monitoring And Predator-Removal Variables Associated With Protection Of The Endangered California Least Tern, Stephanie A. Shwiff, Ray T. Sterner, John W. Turman, Brian D. Foster

United States Department of Agriculture Wildlife Services: Staff Publications

Important nest sites for the endangered California least tern remain at the U.S. Marine Corps Base, Camp Pendleton, CA; these terns comprise approximately 17% of the state’s breeding population. This paper presents an empirical analysis of annual, fixed-cost budgets expended for reproduction-monitoring and predator-removal activities to protect this shorebird. The ex post study covered the inclusive 7-year period between 1995 and 2001. Separate regression analyses were computed using 15 biological (XB), economic (XE), and meteorological (XM) variables. In separate analyses, 14 of these variables served as independent variables to predict each of four dependent tern observation variables (i.e., Ynests, Yeggs, …

Vegetation Characteristics Associated With Small Mammal Populations In The Las Vegas Wash, Christine Therese Herndon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Percent litter, average litter depth, percent bare ground, vegetation density, vegetation canopy, and distance to an ecotone boundary were measured and compared to small mammal capture locations in the Las Vegas Wash. Neotoma lepida appear to be greatly dependent upon the foliage litter of T. ramosissima. Alternatively, ecotone boundaries appear to be the most important factor affecting Dipodomys merriami distributions. Peromyscus eremicus distributions may be predicted based on vegetation density and increased canopy during shorter, winter torpor periods. Chaetodipus penicillatus were consistently associated with dense, seed-bearing vegetation, although C. penicillatus is extremely opportunistic and vegetation density should not limit their …

Livestock Depredation By Wolves, Michael Francis

Rocky Mountain Wolf Recovery: Annual Reports

The state of Colorado expects recovering and dispersing wolf (Canis lupus and C. l. baileyi) populations to reach the state in the near future. Likewise, the western Distinct Population Segment of recovering gray wolves may be delisted soon. In preparation for this eventuality, the Colorado Division of Wildlife (CDOW) has initiated the development of a state wolf management plan in an effort to deal with the many controversial issues surrounding this topic, which includes the possible depredation upon livestock and other domestic animals by wolves. This paper deals specifically with cowcalf and sheep depredation and examines the actual …

Factors Related To Fecal Estrogens And Fecal Testosterone In California Spotted Owls, Brian E. Washburn, Douglas J. Tempel, Joshua J. Millspaugh, R.J. Gutierrez, Mark E. Seamans

United States Department of Agriculture Wildlife Services: Staff Publications

We estimated concentrations of fecal reproductive steroid metabolites in free-ranging California Spotted Owls (Strix occidentalis occidentalis) during the breeding season. We collected fresh fecal samples (n= 142) from 65 individual owls in the Sierra Nevada during April–August of 2001. We developed and validated radioimmunoassay procedures to quantify fecal estrogen metabolites and fecal testosterone metabolites. We used an information- theoretic approach to identify factors that might influence fecal estrogen (E), fecal testosterone (T), and fecal estrogen:testosterone ratio (E:T ratio) levels during the owl’s breeding season. We hypothesized that factors related to sampling procedures, owl characteristics (sex, reproductive …

Monitoring Maize (Zea Mays L.) Phenology With Remote Sensing, Andrés Viña, Anatoly A. Gitelson, Donald C. Rundquist, Galina P. Keydan, Bryan Leavitt, James Schepers

School of Natural Resources: Faculty Publications

Monitoring crop phenology is required for understanding intra- and interannual variations of agroecosystems, as well as for improving yield prediction models. The objective of this paper is to remotely evaluate the phenological development of maize (Zea mays L.) in terms of both biomass accumulation and reproductive organ appearance. Maize phenology was monitored by means of the recently developed visible atmospherically resistant indices, derived from spectral reflectance data. Visible atmospherically resistant indices provided significant information for crop phenology monitoring as they allowed us to detect: (i) changes due to biomass accumulation, (ii) changes induced by the appearance and development of …
