Buth, Chair Several species of fishes have been introduced into the Santa Clara River system in southern California, including Catostomus santaanae (Santa Ana sucker), Catostomus fumeiventris (Owens sucker), Gila orcutti (arroyo chub), and Pimephales promelas (fathead minnow). These species are known to inhabit similar ecological niches but little is known about their associated parasite fauna. Two C. fumeiventris, 35 C. santaanae, 63 hybrid catostomids, 214 G. orcutti, and 18 P. promelas were collected and necropsied in the summers of 2017 and 2018. Nine macroparasite taxa were harvested including seven native, and two nonnative parasites Schyzocotyle acheilognathi (Asian fish tapeworm) and Lernaea cyprinacea (anchor worm). Prevalence and intensity of parasites were not related to the genetic history of these catostomids. This is the first host-association record for G. orcutti with Gyrodactylus sp., S. acheilognathi, ii diplostomid metacercariae, Rhabdochona sp, Contracaecum sp., and larval acuariid cysts and for P. -

Zzyzx Mineral Springs— Cultural Treasure and Endangered Species Aquarium
Cultural and Natural Resources: Conflicts and Opportunities for Cooperation Zzyzx Mineral Springs— Cultural Treasure and Endangered Species Aquarium Danette Woo, Mojave National Preserve, 222 East Main Street, Suite 202, Barstow, California 92311; [email protected] Debra Hughson, Mojave National Preserve, 222 East Main Street, Suite 202, Barstow, California 92311; [email protected] A Brief History of Zzyzx Human use has been documented at Soda Dry Lake back to the early predecessors of the Mohave and Chemehuevi native peoples, who occupied the land when the Spanish explorers first explored the area early in the 19th century. Soda Springs lies in the traditional range of the Chemehuevi, who likely used and modified the area in pursuit of their hunter–gatherer econo- my.Trade routes existed between the coast and inland to the Colorado River and beyond for almost as long as humans have occupied this continent. These routes depended on reliable springs, spaced no more than a few days’ walk apart, and Soda Springs has long been a reliable oasis in a dehydrated expanse. The first written record of Soda Springs Soda Springs, dubbed “Hancock’s Redoubt” comes from the journals of Jedediah Strong for Winfield Scott Hancock, the Army Smith, written in 1827 when he crossed Soda Quartermaster in Los Angeles at the time. The Lake on his way to Mission San Gabriel. Army’s presence provided a buffer between Smith was the first American citizen to enter the emigrants from the East and dispossessed California by land. He crisscrossed the west- natives. California miners also traveled the ern half of the North American continent by Mojave Road on their way to the Colorado foot and pack animal from 1822 until he was River in 1861. -
Santa Clara County Tricolored Blackbird Nesting and Foraging Monitoring Project 2017-2018 Final Report
Santa Clara County Tricolored Blackbird Nesting and Foraging Monitoring Project 2017-2018 Final Report Final Report Prepared for: California Department of Fish and Wildlife & Santa Clara Valley Habitat Agency Prepared by: Ryan Phillips, Andrew Bradshaw, Katie Smith and Claire Ackland Talon Ecological Research Group 421 N. 19th Street San Jose, California 95112 Contact: Ryan Phillips Email: [email protected] Prepared on: September 2019 ABSTRACT During 2017 and 2018, Talon Ecological Research Group (Talon) conducted a comprehensive survey of Tricolored Blackbirds (Agelaius tricolor) throughout Santa Clara County. Financial support for this project was provided by a Natural Community Conservation Program Local Assistance Grant with a matching grant from the Santa Clara Valley Habitat Agency. The goal of the project was to determine the breeding status of the species and better understand their local ecology. Tricolored blackbirds have declined at an alarming rate throughout their range. Recent surveys have shown an 80% decline over the past 90 years and a 63% decline between 2008 and 2014. Within the past 40 years, seven historical nesting colonies were recorded in Santa Clara County. Talon monitoring during the 2017 breeding season found only two of those seven sites had nesting Tricolored Blackbirds. This is a 71.4% decline of nesting colonies in Santa Clara County. This study found that 29 sites had adequate breeding habitat. However, only 4 of those 29 sites (9%) had Tricolored Blackbirds present. Two historic sites and one newly identified site (75% of occupied sites) successfully fledged young in 2017. Two nesting colonies were located on private property (Del Puerto Canyon Road and Highway 130 in San Antonio Valley) and one on public property (Cañada de Los Osos Ecological Reserve). -
Life History Trade-Offs Between Longevity and Immunity in the Parasitic Brown-Headed Cowbird? D
8 The Open Evolution Journal, 2011, 5, 8-13 Open Access Life History Trade-Offs Between Longevity and Immunity in the Parasitic Brown-Headed Cowbird? D. Caldwell Hahn* and Graham W. Smith USGS-Patuxent Wildlife Research Center, Laurel, MD 20708-4039, USA Abstract: Life history theory predicts evolutionary trade-offs between investing in immune defense and other traits. We investigated whether reduced longevity was associated with increased investment in immunity in an avian brood parasite, the brown-headed cowbird (Molothrus ater). Previously we had found that the brown-headed cowbird was unusually re- sistant to infection with West Nile virus and other pathogenic arboviruses when compared with three closely related spe- cies in the same Family, Icteridae, the New World blackbirds. In this study, we hypothesized that the cowbird’s more ef- fective immune responses may be associated with a trade-off in somatic maintenance that results in a shorter lifespan. We measured lifespan using the North American bird banding database and compared the lifespan of the cowbird with the lifespan of red-winged blackbird (Agelaius phoeniceus) and Brewer’s blackbird (Euphagus cyanocephalus), two related species whose immune defenses were previously found less effective against West Nile virus. The cowbird lifespan was significantly shorter than those of both the red-winged blackbird and Brewer’s blackbird. We also found that both male and female cowbirds had a shorter lifespan than the males and females in the two non-parasitic blackbird species. These data suggest that the brown-headed cowbird is a good study species for examining the trade-offs between immunity and longevity. -
A List of Freshwater, Anadromous, and Euryhaline Fishes of California
CALIFORNIA FISH AND GAME California Fish and Game 86(4):244-258 2000 A LIST OF FRESHWATER, ANADROMOUS, AND EURYHALINE FISHES OF CALIFORNIA PETER B. MOYLE Department of Wildlife, Fish, and Conservation Biology University of California, Davis 1 Shields Avenue Davis, California 95616 e-mail: pbmoyle @ ucdavis.edu LIAM H. DAVIS California Department of Fish and Game 7329 Silverado Trail Yountville, California 94558 The freshwater fishes of California include 67 native resident or anadromous species, 53 non-native species, and 5 marine species that occur in fresh water, for a total of 125 species. Within these species, 100 taxa at lower levels (subspecies, Evolutionary Significant Units, runs of anadromous fish) are recognized. The number of freshwater fish species in California is increasing due to invasions of non-native fishes, which are becoming established at a rate of about 1 species every 3 years. Of the native fishes, 5 full species are extinct in California. Thus, the actual number of species maintaining populations in the state is 120. Of extant native species, 15 (22%) are threatened with extinction in the near future. Only 27 native species (40%) can be regarded as having secure populations. INTRODUCTION The fishes of California’s inland waters are a mixture of resident, anadromous, and euryhaline species, both native and non-native. The first attempt to compile a comprehensive list of these species was Evermann and Clark (1931), who listed 78 native species and 32 introduced species. Native species included an anomalous Pacific hagfish, Epatretus stouti, from the Eel River, 14 forms all now considered to be rainbow trout, and 18 other forms that are either no longer recognized as species or were mistakenly considered to be part of the California fish fauna. -

E-mail: [email protected]; [email protected] Abstract The California Roach (Hesperoleucus symmetricus) and Hitch (Lavinia exilicauda) form a species complex largely en- demic to California (CA), USA. Using previous studies of this complex along with a recent comprehensive genomic anal- ysis, we developed a highly supported taxonomic hierarchy of two genera, five species, four subspecies and multiple distinct population segments within two presently recognized species. The genera Lavinia and Hesperoleucus are support- ed as representing distinct lineages, despite occasional hybridization between them. While hybridization is one pathway to some speciation in this complex, hierarchical levels correlate nicely between genomic results and earlier morphological work. Hesperoleucus symmetricus is newly divided into four species (H. parvipinnis—Gualala Roach, H. mitrulus— Northern Roach, H. venustus—Coastal Roach, and H.
