  • Bears in Oklahoma
    April 2010 Bears in Oklahoma Our speaker for the April 19 meeting of the Oklahoma City Audubon Society will be Jeremy Dixon, wildlife biologist at the Wichita Mountains Wildlife Refuge. His presentation is titled “The Strange But True History of Bears in Oklahoma.” For many years Jeremy was a biologist in Florida where he studied the interactions between black bears and humans. His master’s research was on the Conservation Genetics of the Florida Black Bear. Jeremy moved to Lawton in 2009 to experience life out here in the middle of the continent. Our grass prairie and ancient granite mountains are a new living environment for him. However, the black bears are coming back across Oklahoma from the east presenting birders an experience with a new and large predator to which we are unaccustomed. With an education from Jeremy, hopefully we can learn how to watch the birds while not feeding the bears ourselves. Come out for bear-hugging good time at bird club and bring a friend. County Birding: Kingfisher Jimmy Woodard On March 11, the group of 7 birders entered Kingfisher County in the far southeast corner. We located several small lakes with waterfowl: Canada Geese, Gadwall, Mallard, Green- Winged Teal and Ruddy Duck. We also found an adult Bald Eagle, the first of two found during the trip. Driving the back roads, we observed Great Horned Owl, Phoebe, King- fisher, and a bunch of sparrows – Harris, White Crowned, Song, Savannah, & Lincoln’s. We visited fields along the Cimarron River southeast of Dover. Carla Brueggen & her hus- band lease fields in this area.

  • Genetic Structure of the North American Porcupine (Erethizon Dorsatum) Across Western Texas
    GENETIC STRUCTURE OF THE NORTH AMERICAN PORCUPINE (ERETHIZON DORSATUM) ACROSS WESTERN TEXAS by Erica D. Thomas A Thesis Submitted in Partial Fulfillment Of the Requirements for the Degree MASTER OF SCIENCE Major Subject: Biology West Texas A&M University Canyon, Texas December 2017 Approved: Rocky Ward, PhD Date Chairman, Thesis Committee W. David Sissom, PhD Date Member, Thesis Committee William P. Johnson, M.S. Date Member, Thesis Committee W. David Sissom, PhD Date Department Head Dean, Academic College Date Angela N. Spaulding Date Dean, Graduate School ii ABSTRACT The North American porcupine (Erethizon dorsatum) is a highly mobile, generalist species with an extensive geographical distribution in North America. The porcupine was first documented in southwestern Texas in the early 20th century, but today occurs in most of the western two-thirds of the state. This species is relatively unstudied within the Great Plains ecoregion of North America, with no genetic studies having been conducted for this species in Texas. The objectives of this study were to describe population genetic metrics of porcupines across 3 ecoregions in western Texas by examining variation in 17 polymorphic microsatellites, and to confirm the applicability of the zinc finger protein sequencing method to identify sex in a population of North American porcupines. Tissue samples from 106 porcupines were collected from the High Plains, Rolling Plains, and Edwards Plateau ecoregions of western Texas. Sex was accurately identified for 92 porcupine tissue samples by directly sequencing a short portion (195 base pairs) of the zinc finger protein gene. Sixteen base pair substitutions between Zfx and Zfy chromosomes denoted the sex of individuals; heterozygous sequence for males (Zfx and Zfy), homozygous sequence for females (Zfx only).

BARRON1 1Department of Life, Earth and Environmental Sciences, West Texas A&M University, Box 60808, Canyon, TX 79016-0001 2Current address: Texas Parks and Wildlife Department, P.O.Box 226, Karnack, TX 75661 3Corresponding author; Internet: [email protected] 4Texas Parks and Wildlife Department, P.O. Box 659, Canyon, TX 79015 Abstract.—Migration chronology was quantified for 15 waterfowl species on 58 playa wetlands in the Southern High Plains of Texas from February 2004 through April 2006. Abundance of each species was estimated on playas once every two weeks during the nonbreeding season (16 August to 30 April); presence of ice was also recorded. Dabbling ducks were most common (N = 250,668) and most tended to exhibit either a bimodal migration pattern (lower abundance in winter than during fall and spring passage) or a unimodal pattern (one defined peak). Abun- dance of the most common dabbling ducks was skewed toward late winter and spring. Most species of diving ducks (N = 15,128) tended to exhibit irregular migration patterns. Canada Geese (both Branta canadensis and B. hutchinsii, N = 15,347) had an abundance pattern that gradually increased, peaking in midwinter, and then decreased, which is typical for a terminal wintering area. Ice was most common on playas during the first half of December, which coincided with the lowest winter abundance in dabbling ducks. Data from this study will support management ef- forts focused on playa wetlands, including the development of population goals and habitat objectives that span the entire non-breeding season.

  • Response to CEQA Comments
    Attachment 7: Response to CEQA comments Responses to verbal comments received during the 03/14/2019 Planning Commission Hearing on the Public Draft IS/MND/IEC document Comment Jeff Marcus -1 (PCE groundwater contamination and the Tahoe Asphalt Plant) Mr. Marcus stated concern about snow removal and American Disability Act (ADA) access. Mr. Marcus discussed general concern about repaving and dust control actions at the Tahoe Asphalt Plant, and stated concern about groundwater contamination, more specifically the health dangers of PCE. Lead Agency Response to Jeff Marcus (Verbal Comments 03/14/2019) The comments presented are not specific to the Project or project area. City general snow removal actions are part of the Operations and Maintenance Program. ADA access ramps are constructed with City-managed sidewalk and bike trail projects. Dust control measures must comply with El Dorado County Air Quality Management District Rule 223. The PCE contamination plume originates at Lake Tahoe Laundry Works at the Raley's Center and has migrated north towards Lake Tahoe (and remains outside of the Greenbelt and Bonanza portions of the project area) and at depths that extend below any 5-8 foot excavations that may be necessary for stormwater improvements on the north side of US Highway 50, should the plume direction change. Melanie Greene of Cardno, the firm that prepared the project-level analysis and environmental document, spoke to the information presented by Mr. Marcus related to PCE groundwater contamination, confirming that the Project posed no risk of exposing PCE contaminated groundwater. The South Tahoe “Y” PCE investigation and remediation efforts are in an adjacent catchment (west of the project boundary) and is a groundwater contamination issue from past use of dry cleaning solvents and metal degreasers containing tetrachloroethylene (PCE).

  • Haldane's Rule and American Black Duck × Mallard Hybridization
    1827 NOTE / NOTE Haldane’s rule and American black duck × mallard hybridization Ronald E. Kirby, Glen A. Sargeant, and Dave Shutler Abstract: Species ratios and rangewide distributions of American black ducks (Anas rubripes Brewster, 1902) and mal- lards (Anas platyrhynchos L., 1758) have undergone recent changes. Mechanisms behind these changes are not known with certainty, but recent investigations have focused on the possibility of competitive exclusion and the consequences of hybridization. Consequences of hybridization have been difficult to assess because of the difficulty in identifying hy- brids beyond the F1 generation and lack of means to quantify introgression in wild populations. We documented a postmating isolating mechanism between the two species that follows Haldane’s rule in controlled, interspecific matings in captive populations. Hybridization reduces the proportion of F1 females available to return to the breeding grounds in the subsequent year. This effect, although likely small in overall population consequences in any year, may be of lo- cal significance and may contribute to recent reports of range shifts in both American black ducks and mallards. Résumé : L’importance relative des canards noirs (Anas rubripes Brewster, 1902) et des canards colverts (Anas platyr- hynchos L., 1758) et leur répartitiol’échelle de leur aire totale ont encouru des modifications récentes. Les mécanismes responsables de ces changements ne sont pas connus avec précision, mais des études récentes ont examiné l’exclusion par compétition et les conséquences de l’hybridation. Les conséquences de l’hybridation sont difficiles à évaluer car il n’est pas facile d’identifier les hybrides au-delà de la génération F1 et il n’y a pas de moyen pour quantifier l’introgression chez les populations sauvages.

Schacht, Range Scientist, Department of Agronomy and Horticulture, University of Nebraska–Lincoln Lars C. Anderson, Range Ecologist, Department of Agronomy and Horticulture, University of Nebraska–Lincoln William L. Vodehnal, Certified Wildlife Biologist, Nebraska Game and Parks Commission reater prairie-chickens fascinate landowners, hunters, and birders Galike. They are a symbol of the natural heritage of the Great Plains. Their colorful mating rituals decorate pastures, and their booming calls add charm to meadows. Many landowners want to learn more about managing pastures to increase the number of greater prairie-chickens. Some have a personal desire to conserve the species. Others recognize that these native grouse offer income opportunities in the form of fee hunting and ecotourism. The more information landowners have, the easier it will be to find these birds and make sure they flourish year after year. Whatever your interest in greater prairie-chickens, learning more about this interesting species will help you maintain their habitat while you maintain your land. Stuhr Museum of the Prairie Pioneer Millions of greater prairie-chickens once inhabited the vast prairies in the Midwest. Their numbers were so great that in the late 1800s and early 1900s, a so- called “chicken hunting culture” was created. The loss of habitat was, by far, the biggest reason for the dramatic decline in prairie-chicken numbers, but hunting was another factor.

  • Utilization of Hydrilla Verticillata by Wintering Waterfowl on the Tidal Potomac River
    UTILIZATION OF HYDRILLA VERTICILLATA BY WINTERING WATERFOWL ON THE TIDAL POTOMAC RIVER by Jeffrey A. Browning Advisor: Dr. Albert Manville Presented to the Faculty of the Graduate School of Johns Hopkins University In Partial Fulfillment of the Requirements For the Degree of Master of Science Johns Hopkins University May 2008 ABSTRACT Submersed aquatic vegetation (SAV) communities in the tidal Potomac River were decimated during the 20th century by multiple environmental and anthropogenic factors. With the major declines of SAV communities, waterfowl populations have declined greatly as well (Hindman 1989). Hydrilla verticillata, an introduced submersed aquatic plant, was first discovered in the tidal Potomac River in 1982 (Steward et al. 1984). One hundred nine waterfowl were collected from the tidal Potomac River and its tributaries during the 2007-2008 Virginian and Maryland waterfowl hunting seasons. The esophagi and gizzards were dissected and analyzed to determine the utilization of H. verticillata by wintering waterfowl. Only 2 duck species, Mallard (Anas platyrhynchos) and Lesser Scaup (Aythya affinis), consumed small amounts of H. verticillata, 2.52% and 0.20% aggregate percentage of esophageal content, respectively. An inverse relationship between H. verticillata and gastropod consumption was observed as the season progressed. i ACKNOWLEDGMENTS I would like to thank Dr. Albert Manville for his guidance and input during this research. Dr. Manville helped me reach decisions and get past certain obstacles. I would also like to thank Dr. Matthew Perry and Mr. Peter Osenton at the USGS Patuxent Wildlife Research Center for advice and consultation during the design of this study and analysis of the data.
