This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Invertebrates are among the most imperiled species on Earth, with an estimated one in five facing extinction in the near future. Habitat loss, invasive species and pollution all contribute to the loss of invertebrate biodiversity, especially those that persist in fragmented ecosystems. The Lange's Metalmark butterfly (Apodemia mormo langei), a subspecies of the more widespread Mormon Metalmark (Apodemia mormo), is such an example, having been listed as endangered under the Federal Endangered Species Act in 1976, and endemic to a small stretch of relict dunes along the San Joaquin River near the town of Antioch, California, in what is now the Antioch Dunes National Wildlife Refuge (NWR). Industrial and urban pressures have degraded the sand dune habitat of the Lange's Metalmark from mobile sandy areas supporting stands of their host plant, the Antioch Dunes buckwheat (Eriogonum nudum var. psychicola) to a stabilized dune system overrun by invasive grasses and forbs. Peak flight numbers of the insect have been on the decline since 1999, hitting a critical low of 45 in 2006, and a mere 28 in 2013. By examining the historical geography of the Antioch Dunes NWR, the seasonal averages of precipitation and temperature, and atmospheric aerosols deposited on site, this research aims to better understand abiotic factors contributing to habitat decline at the Antioch Dunes NWR, and, ultimately, to population decline of the Lange's Metalmark butterfly. Ultimately, the objective is that this research adds to a larger body of work whose goal is to restore habitat for and increase the population of the butterfly. Chapter One looks at the historical ecology of the Antioch Dunes, and investigates the origin and age of the dune system, which allows for a better understanding of how long the Lange's Metalmark and its ecosystem have existed at the Antioch Dunes. Anthropogenic uses and disturbances are also tracked through time and their role in population decline of the insect and degradation of its habitat discussed. In Chapter Two, multiple regression models were used to look at the influence of seasonal climatic variability on the population of the Lange's Metalmark. In all model iterations, average spring precipitation had a negative effect on population growth rate response, with higher spring precipitation leading to lower counts (i.e., peak flight numbers) of the butterfly, most likely through indirect effects on the vegetation, especially favoring the invasive, non-native annual plants. Lastly, the role of atmospheric aerosol deposition on the Antioch Dunes ecosystem is examined in Chapter Three, which quantifies how much particulate matter is deposited during the peak flight period of the Lange's Metalmark. Signatures of calcium, sulfur, magnesium, and sodium were particularly high, and can be attributed directly to the Georgia Pacific gypsum plant in close proximity to the Antioch Dunes National Wildlife Refuge. The input of nitrate and ammonia is also significant. The role of these particulates with regard to soil nutrients and changing the ecosystem from oligotrophic to more eutrophic is also discussed. Recommendations are made for both management actions and further research for this imperiled sand dune ecosystem and its endangered, endemic species.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Lange's Metalmark Butterfly (Apodemia mormo langei) is an endangered species endemic to the Antioch Dunes National Wildlife Refuge in Antioch, California, where its sole host plant, Antioch Dunes Buckwheat (Eriogonum nudum var. psychicola), has historically thrived on an active mobile sand dune landscape. In recent years, the dunes have stabilized largely as a result of invasive annual plants that disrupt historic aeolian processes. It has been speculated that this stabilization, along with smothering of buckwheat stands by invasive annual plants and associated changes to the physical environment, are largely responsible for declining stands of Antioch Dunes Buckwheat and, as a result, Lange's Metalmark Butterfly. This study examines microclimatological variations between healthy buckwheat stands on active, mobile sand and stands overgrown and stabilized by non-native plants. The resulting data is intended to increase the growing body of knowledge concerning the environment of the buckwheat and butterfly as well as the environmental variables that infer the most advantageous locations to plant new buckwheat, release butterfly larvae reared in captivity, and otherwise manage the refuge for these rare and endangered species. Ultimately, the purpose of this research is to assist the larger goal of restoring the refuge ecosystem and landscape.

This book was released on 2023-11-10 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carnivorous pitcher plants, pygmy conifers, and the Tiburon jewel flower, restricted to a small patch of serpentine soil on Tiburon Peninsula in Marin County, are just a few of California's many amazing endemic plants—species that are unique to particular locales. California boasts an abundance of endemic plants precisely because it also boasts the richest geologic diversity of any place in North America, perhaps in the world. In lively prose, Arthur Kruckeberg gives a geologic travelogue of California's unusual soils and land forms and their associated plants—including serpentines, carbonate rocks, salt marshes, salt flats, and vernal pools—demonstrating along the way how geology shapes plant life. Adding a fascinating chapter to the story of California's remarkable biodiversity, this accessible book also draws our attention to the pressing need for conservation of the state's many rare and fascinating plants and habitats. *148 outstanding, accurate photographs, more than 100 incolor, illustrate California's diverse flora *Covers a wide range of locations including the Channel Islands, the Central Valley, wetlands, bristlecone pine forests, and bogs and fens *Provides selected trip itineraries for viewing the state's geobotanical wonders *Includes information on human influences on the California landscape from the early Spanish explores through the gold rush and to the present
