Virginia’S Amphibians: Status, Threats And Conservation, Jennifer Sevin, John D. Kleopfer

Virginia Journal of Science

Virginia’s diverse environments support 84 amphibian species (anurans and caudates), making it the third highest state in terms of species richness. However, the Commonwealth matches the global trend in declining amphibian populations with over one-third of its amphibian species in conservation need. The Species of Greatest Conservation Need included in the most recent Virginia Wildlife Action Plan cut across amphibian families and ecoregions. It is challenging to ascertain the exact cause of most of the population declines. In one degree or another, all of the global threats to amphibians exist within Virginia’s borders. While an active research program on amphibians …

Freshwater Mussels Of Virginia (Bivalvia: Unionidae): An Introduction To Their Life History, Status And Conservation, Jess W. Jones

Virginia Journal of Science

With 77 species, the mussel fauna of Virginia is one of the most diverse in the United States. Fifty-four species or ~70% of the state’s mussel fauna occurs in the rivers of the upper Tennessee River basin, especially in the Clinch and Powell rivers of southwestern Virginia. An additional 23 species reside in rivers of the Atlantic Slope, including the Potomac, Rappahannock, York, James and Chowan basins, and in the New River, a major tributary to the Ohio River. A total of 39 species or 51% of Virginia’s mussel fauna is listed as federally endangered, state endangered or state threatened. …

Breeding Birds Of Virginia, Bryan D. Watts

Virginia Journal of Science

Virginia supports a diverse community of breeding birds that has been the focus of investigation for more than 400 years. The avifauna reflects the latitudinal position of the state and the fact that the border extends from the Atlantic Ocean to the Appalachian Mountains. A total of 224 species have been recorded breeding in Virginia, 214 of which are extant. Twenty species have colonized the state since 1900 including 14 since 1950. Of all extant species, 102 (48%) are considered common at least somewhere in the state and 64 (30%) are rare to very rare. Diversity varies by physiographic region …

Status Of Plants In Virginia, Michael H. Renfroe

Virginia Journal of Science

OVERVIEW OF BOTANICAL DIVERSITY

Virginia possesses a unique and varied assemblage of plant life. There are 3,164 species, subspecies and varieties of plants in Virginia (Weakley et al. 2012). As classified by the Virginia Department of Conservation and Recreation’s Division of Natural Heritage (DCR-DNH), they form some 94 ecological groups and 317 community types across five distinct physiographic provinces: Coastal Plain, Piedmont, Blue Ridge, Ridge and Valley, and Appalachian Plateau. The state extends 469 miles from east to west and 201 miles north to south at the widest points, enclosing 42,326 square miles of territory. This diverse range of environmental …

Virginia’S Land Mammals: Past And Present, With Some Thoughts About Their Possible Future, John F. Pagels, Nancy D. Moncrief

Virginia Journal of Science

Mammals encountered today in Virginia’s forests and fields include native and nonnative species, feral populations, and free-ranging pets. We examine factors that have influenced Virginia’s terrestrial mammal fauna since the arrival of European colonists in the 1600s and some of the factors that are shaping the fauna today. We look in depth at changes since Handley and Patton’s (1947) first complete monograph on Virginia mammals and augment Linzey’s (1998) book, The Mammals of Virginia. We include current nomenclature, baseline information, and references to comprehensive literature. We discuss some of the current and developing anthropogenic factors that have impacted, or that …

Forest Diversity And Disturbance: Changing Influences And The Future Of Virginia’S Forests, Christine J. Small, James L. Chamberlain

Virginia Journal of Science

The Virginia landscape supports a remarkable diversity of forests, from maritime dune woodlands, swamp forests, and pine savannas of the Atlantic Coastal Plain, to post-agricultural pine-hardwood forests of the Piedmont, to mixed oak, mesophytic, northern hardwood, and high elevation spruce-fir forests across three mountain provinces in western parts of the state. Virginia’s forests also have been profoundly shaped by disturbance. Chestnut blight, hemlock woolly adelgid, emerald ash borer, and other pests have caused declines or functional extirpation of foundation species. Invasive plants like multiflora rose, Oriental bittersweet, and Japanese stiltgrass threaten both disturbed and intact forests. Oaks and other fire-dependent …

Sea Level Rise In Virginia – Causes, Effects And Response, Tal Ezer, Larry P. Atkinson

Virginia Journal of Science

Sea level rise (SLR) along Virginia’s coasts and around the Chesapeake Bay as measured by tide gauges is analyzed and discussed. It is shown that the SLR rates vary between one location to another and in most locations the rates increase over time (i.e., SLR is accelerating). The latest science of SLR is reviewed and the causes of the high SLR rates in Virginia are discussed. The impacts of land subsidence and ocean currents (changes in the Gulf Stream in particular) on sea level are especially notable and important for predicting future SLR in Virginia. The consequences of SLR on …

Viewing The Status Of Virginia’S Environment Through The Lens Of Freshwater Fishes, Paul L. Angermeier, Michael J. Pinder

Virginia Journal of Science

We summarize a range of topics related to the status of Virginia’s freshwater fishes, their reflection of environmental quality, and their contribution to human wellbeing. Since 1994 the list of extant Virginia fishes has lengthened from 210 species to 227 species, mostly due to taxonomic reorganizations. Virginia’s list of Species of Greatest Conservation Need currently contains 96 fish species, predominated by darters (32 species) and minnows (28 species). Increasing trends in species rarity and threats to fishes suggest that Virginia’s aquatic environment is becoming less hospitable for fishes. Prevailing anthropogenic threats to fishes include agriculture, urban development, mineral extraction, forestry, …

Virginia Air Quality: Trends, Exposure, And Respiratory Health Impacts, James Blando, My Ngoc Nguyen, Manasi Sheth-Chandra, Muge Akpinar-Elci

Virginia Journal of Science

Air quality is an important determinant of public health and quality of life. A secondary data analysis was carried out to investigate trends and air quality in Virginia. The analysis included an evaluation of two major air pollution source categories, emission of criteria and hazardous air pollutants, ambient concentrations of criteria pollutants, ozone standard violations and associated meteorology, and hospital admissions for asthma and chronic obstructive pulmonary disease in Virginia. Comparisons were also made to national trends and statistics. Data was gathered from many open reputable on-line sources available through various state and federal agencies. Virginia routinely meets 5 of …
