Major Advisor: Dr. RE-ROUGHLEY. .4mphizoidae is a family of the Suborder Adephaga of Coleoptera. There is only the single genus Ampltizoa. of which there are six species known in the world. There are three species in western North America: Amphboa insolens LECONTE 1 853, Amplzizoa leconrei MATII~EWS1872, and Amphizoa striata VAN DYKE1927, and three in China: Amphizoa davidi LUCAS 1882, Amphizoa sinica YU AND STORK 1991, and Amphizoa smeranai ROUGHLEY,XIE AND YU (in press). In this paper, the morphology, geographical distribution and habitat of each species in its larval stages are described, and certain characteristics of fom and structure are illustrated. Keys for identification of amphizoid Iarvae of hown species are presented for the first time. This study is based mainly on chaetotaxal analysis, a method of studying the serae and pores of immature stages. The chaetotaxal patterns of first instar larvae of five species of Amphizoa, and one species of Hygrobiidae (referred to as the out-goup) are described. The phylogenies of Hydradephaga and Amphizoidae were reconstnicted from these data. The origin of amphizoids is hypothesized to have occurred somewhere on Pacifica. a set of supposed continental masses, in the latc Permian or early Triassic. These areas would havc been highland areas with glaciations and ice cover during that tirne. As early as the Permian times, the amphizoid fauna originated within and adapted to high altitude, periglacial conditions, and cold lotic habitats. Then the arnphizoids drifted northward on thesc land masses of Pacifica, and split up into the Asian and North American branches. The Asian branch reached its present position, Sichuan Province, probably with the Yan-e block. The Nonh American lineage also speciared durkg the drifiing. One of these reached its location of Jilin Province with the Sino-Korean block, and others went to western Noah America with some Pacifica masses kom late Jurassic and early Cretaceous to the early Teniary. The present pattern of dismbution in geographical variation abo reflects a history of the development of the Himalayan Mountains and RocLy Mountain ranges, and of the repeated episodes of isolation and dispersal of these species during the various Pleistocme glaciations. Key words: Coleoptera; Adepbaga; Amphizoidae; immature stages; chaetotaxy; origin. 1 wish to express my sincere appreciation to my advisor, Dr. ROBERTE.

    Little Applegate Watershed Hydrology Report Michael Zan * Hydrologist April 1995 Little Applegate Watershed Analysis Hydrology Report SECTION 1 LITTLE APPLEGATE RIVER HYDROLOGY Mean Monthly Flows: Except for some data collected from May through October 1913, and from June through October 1994. there is no known flow data for the Little Applegate River or its tributaries. With this in mind it was necessary to construct a hydrograph displaying mean monthly flows by utilizing records from nearby stations that have been published in USGS Surface Water Records and Open-File Reports. In constructing a hydrograph, a short discussion of low flows is first in order. Since low streamflows have been identified as a key question pertaining to the larger issues of water quantity/quality and fish populations, the greatest need is to gain a reasonable estimate of seasonal low flows to help quantify the impacts of water withdrawals on instream beneficial uses. With this in mind, extreme caution must be used when extrapolating data from gaged to ungaged watersheds. This is particularly important in determining low-flow characteristics (Riggs 1972, Gallino 1994 personal communications). The principle terrestrial influence on low flow is geology and the primary meteorological influence is precipitation. Neither have been adequately used to describe effects on low flow using an index so that estimation of low flow characteristics of sites without discharge measurements has met with limited success. Exceptions are on streams in a region with homogeneous geology, topography, and climate, in which it should be possible to define a range of flow per square mile for a given recurrence interval.

XIE & P. Yu Abstract A new species, Amphizoa smetanai (Coleoptera: Amphizoidae), is described from Emci Shan, Sichuan Province, China. The adult female of Amphizoa davidi LUCAS is described for the first time in this paper. A revised key to the adults of all six known species (three North American and three Chinese) of Amphizoa is provided. Key words: Coleoptera, Amphizoidae, Amphizoa davidi, Amphizoa smetanai, new species, China. Introduction The family Amphizoidae includes only one genus, Amphizoa LECONTE, 1853, and presently it consists of six known species. There are three species in western North America: A. insolens LECONTE, 1853, A. striata VAN DYKE, 1927, and A. lecontei MATTHEWS, 1872, and three in China: A. davidi LUCAS, 1882, A. sinica Yu & STORK, 1991, and A. smetanai sp.n. In North America, amphizoids are restricted to the western states and provinces from Alaska south to southern California and east to central Wyoming and Colorado. The Chinese species occur in Jilin and Sichuan.

Internal and external structures of the head of 3'''' instar larvae of Amphizoa lecontei Matthews 1872 were examined and interpreted phylogenetically. 2.) The presence of strongly developed, complex ventral pharyngeal dilator muscles is con- sidered as a possible synapomorphy of Trachypachini and Hydradephaga excl. Gyrinidae. 3.) Caudal tentorial arms, the complete loss of the lacinia, and the origin of the galea from the unsclerotized mesal side of palpomere I are considered as synapomorphies of a monophy- letic unit comprising Trachypachini, Noteridae, Amphizoidae, Hygrobiidae, and Dytiscidae. 4.) Separation of the posterior tentorial grooves as found in larvae of Haliplidae, Noteridae, Amphizoidae, Hygrobiidae, and Dytiscidae is a feature vi^hich has probably evolved several times independently. 5.) The articulation of the maxilla with an elongated, flexible process of the anterior margin of the head capsule is a possible synapomorphy of Noteridae, Amphizoidae, Hygrobiidae, and Dytiscidae.

  • Asian Spirituality of Christian Stewardship (Keynote Address of the Rev
    Asian Spirituality of Christian Stewardship (Keynote Address of the Rev. Dr. Winfred B. Vergara, Missioner for Asiamerica Ministry of the Episcopal Church Center at the diocesan EAM Consultation of the Diocese of California, held in Christ Episcopal Church, Alameda, California on June 10-11, 2011) Introduction This gathering today, here in this Diocese of California has a triple significance for me: first, it is here, in this diocese where the first national Episcopal Asiamerica Ministry Consultation was held in 1974; second, it is here, in this Diocese, where I was installed as the second missioner for Asiamerica Ministry in 2004; and third, it is here now, in this Diocese that this first diocesan-wide EAM Consultation is ever held. The end of all exploring,” wrote the English poet, T. S. Eliot, “will be to arrive where you started and know the place for the first time.” Or as one Chinese proverb says, “If you just stay in the same place for as long as you can, you will finally see the world coming back to you.” So I feel like, today, it is “dejavu” – all coming back again, as if, for the first time. You‟ve assigned me to speak on “Asian Spirituality of Christian Stewardship.” Let me arranged this theme on three chapters: first, what is spirituality; second, what is Asian; and third, what is Christian stewardship. Then, I will sum up on how we can arrive at a contextual teaching on Christian Stewardship. First, what is Spirituality? A story is told of a parrot which was fond of speaking bad words.

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.

    Snake Surveys in Jackson, Josephine and Southern Douglas Counties, Oregon JASON REILLY ED MEYERS DAVE CLAYTON RICHARD S. NAUMAN May 5, 2011 For more information contact: Jason Reilly Medford District Bureau of Land Management [email protected] Introduction Southwestern Oregon is recognized for its high levels of biological diversity and endemism (Whittaker 1961, Kaye et al. 1997). The warm climate and broad diversity of habitat types found in Jackson and Josephine counties result in the highest snake diversity across all of Oregon. Of the 15 snake species native to Oregon, 13 occur in the southwestern portion of the state and one species, the night snake, is potentially found here. Three of the species that occur in Oregon: the common kingsnake, the California mountain kingsnake, and the Pacific Coast aquatic garter snake are only found in southwestern Oregon (Table 1, St. John 2002).
