This biological opinion analyzes the project’s effect on Sonora tiger salamander (Ambystoma tigrinum stebbinsi) (STS) and Chiricahua leopard frog (Rana chiricahuensis) (CLF) in accordance with section 7 of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). We received your February 20, 2003 request for formal consultation on February 21, 2003. In that request, you determined that suppression activities associated with the Ryan fire likely adversely affected CLF and STS. You have also requested our concurrence that suppression activities may have affected, but did not likely adversely affect, lesser long-nosed bat (Leptonycteris curasoae yerbabuenae), Huachuca water umbel (Lilaeopsis schaffneriana ssp. recurva), Canelo Hills ladies’ tresses (Spiranthes delitescens), and Gila topminnow (Poeciliopsis occidentalis occidentalis). Our concurrences are provided in Appendix A. This biological opinion is based on information provided in the January 28, 2003 biological assessment (BA). Literature cited in this draft biological opinion is not a complete bibliography of all literature available on the species of concern, wildfire suppression and its effects, or on other subjects considered in this opinion.

ZooKeys 547: 165–192. doi: 10.3897/zookeys.547.6018 Abstract The taxonomic circumscription of the large and diverse leaf beetle genusChrysolina Motschulsky is not clear, and its discrimination from the closely related genus Oreina Chevrolat has classically been controver- sial. In addition, the subgeneric arrangement of the species is unstable, and proposals segregating Chryso- lina species into new genera have been recently suggested. In this context, the availability of a phylogenetic framework would provide the basis for a stable taxonomic system, but the existing phylogenies are based on few taxa and have low resolution.

UNDER SECRETARY OF COMMERCE FOR OCEANS AND ATMOSPHERE AND NOAA ADMINISTRATOR NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION U.S. DEPARTMENT OF COMMERCE OVERSIGHT HEARING ON THE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION’S FY 2008 BUDGET REQUEST BEFORE THE COMMITTEE ON NATURAL RESOURCES SUBCOMMITTEE ON FISHERIES, WILDLIFE AND OCEANS U.S. HOUSE OF REPRESENTATIVES February 27, 2007 Madam Chairwoman and members of the Subcommittee, before I begin my testimony I would like to thank you for your leadership and the generous support you have shown the National Oceanic and Atmospheric Administration (NOAA). Your continued support for our programs is appreciated as we work to improve our products and services for the American people. Thank you for the opportunity to testify on the President’s Fiscal Year (FY) 2008 Budget Request for NOAA. The FY 2008 President’s Budget supports NOAA’s priority to advance mission-critical services. The FY 2008 request is $3.815 billion, which represents a $131 million or 3.4% increase over the FY 2007 request. This request includes the level of resources necessary to carry out NOAA’s mission, which is to understand and predict changes in the Earth’s environment, and conserve and manage coastal and marine resources to meet our nation’s economic, social and environmental needs. At NOAA we work to protect the lives and livelihoods of Americans, and provide products and services that benefit the economy, environment, and public safety of the nation. Before I discuss the details of our FY 2008 budget request, I would like to briefly highlight some of NOAA’s notable successes from the past fiscal year (2006).

    DISSERTATION VIABILITY AND INVASIVE POTENTIAL OF HYBRIDS BETWEEN YELLOW TOADFLAX (LINARIA VULGARIS) AND DALMATIAN TOADFLAX (LINARIA DALMATICA) Submitted by Marie F.S. Turner Department of Soil and Crop Sciences In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Fall 2012 Doctoral Committee: Advisor: Sarah Ward Christopher Richards David Steingraeber George Beck Sharlene Sing Copyright by Marie Frances Sundem Turner 2012 All Rights Reserved ABSTRACT VIABILITY AND INVASIVE POTENTIAL OF HYBRIDS BETWEEN YELLOW TOADFLAX (LINARIA VULGARIS) AND DALMATIAN TOADFLAX (LINARIA DALMATICA) Although outcomes of hybridization are highly variable, it is now considered to play an important role in evolution, speciation, and invasion. Hybridization has recently been confirmed between populations of yellow (or common) toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria dalmatica) in the Rocky Mountain region of the United States. The presence of hybrid toadflax populations on public lands is of concern, as both parents are aggressive invaders already listed as noxious weeds in multiple western states. A common garden experiment was designed to measure differences in quantitative (shoot length, biomass, flowering stems, seed capsule production) phenological (time of emergence, first flowering and seed maturity) and ecophysiological (photosynthesis, transpiration and water use efficiency (WUE)) traits for yellow and Dalmatian toadflax, F1 and BC1 hybrids, as well as natural field-collected hybrids from two sites. Genotypes were cloned to produce true replicates and the entire common garden was also replicated at two locations (Colorado and Montana); physiological data were collected only in Colorado. All genotypes grew larger and were more reproductively active in Colorado than in Montana, and hybrids outperformed parent taxa across vegetative and reproductive traits indicating heterosis.
