Phenotypic Variation in Climate-Associated Traits of Red Spruce (Picea rubens Sarg.) along Elevation Gradients in the Southern Appalachian Mountains

Red spruce (Picea rubens) is a long-lived tree species that thrives in cool, moist environs. Its ability to adapt to rapidly changing climate is uncertain. In the southern Appalachian Mountains, red spruce reaches its greatest abundance at high elevations, but can also occur across a range of mid and lower elevations, suggesting the possibility of a correlation between genetic variation and habitat. To assess clinal phenotypic variation in functional traits related to climate adaptation, we collected seed from 82 maternal sib families located along replicated elevational gradients in the Great Smoky Mountains National Park, TN (GSMNP) and Mount Mitchell State

Scientific Note: Facultative Perenniality in the Dwarf Sundew (Drosera brevifolia)

Please note that the initial PDF issued was paginated incorrectly.  The correctly paginated article appears at this link. ABSTRACT: The dwarf sundew (Drosera brevifolia) occurs from Uruguay to Virginia. Disjunct populations occur in the southeastern U.S. with the northernmost in Kentucky. Despite this wide distribution, relatively little is known about the biology of this species. It has been described as both annual and biennial. The endangered Kentucky population is considered biennial, but occasionally, live, mature plants have dead flower stalks in early autumn suggesting some may be perennial. In 2013, 40 sundews that germinated in the fall of 2012 were

The Demography of Gentiana autumnalis in Populations Under Varying Management Regimes in New Jersey

Please note that the initial PDF issued was paginated incorrectly.  The correctly paginated article appears at this link. ABSTRACT: Gentiana autumnalis (pine barren gentian) is a rare, fall-flowering perennial that is endemic to pine barren habitat from New Jersey to South Carolina. This disturbance-adapted, early successional species is at risk in New Jersey as a result of human interactions, namely growing season mowing and fire suppression. We used a repeated measures design to compare the differences between managed (mowing and prescribed fire) and unmanaged G. autumnalis populations for density, life stage, mortality, and fecundity. Managed populations had a greater gentian

The Genetic Diversity and Population Structure of Geum radiatum: Effects of a Past Augmentation of an Endangered Hexaploid

ABSTRACT Geum radiatum is a federally endangered high-elevation rock-outcrop endemic herb that is widely recognized as a hexaploid and a relic species. Little is known about G. radiatum genetic diversity, population interactions, or the effect of past augmentations of populations. This study sampled every known population of G. radiatum and used microsatellite markers to measure genetic diversity and population structure. The analysis demonstrates that there is interconnectedness and structure among populations. In addition, the analysis was able to differentiate transplanted individuals and identify putative anthropogenically admixed individuals within augmented populations. Geum radiatum exhibits diversity within and among populations and current

The Vascular Flora of Orchard Knob Reservation, Chattanooga, Tennessee

Orchard Knob is a 2.5 ha National Military Park near downtown Chattanooga, Tennessee. This historic site protects a bubble of limestone glade and xeric limestone prairie habitat in an otherwise heavily developed, urban area. A floristic survey was conducted across two growing seasons, yielding 212 taxa across 152 genera and 58 families. Seventy-four non-native taxa were documented, about 35% of the total flora. Six rare, state-ranked species were documented: Baptisia aberrans, Clematis fremontii, Hypericum dolabriforme, Packera paupercula var. appalachiana, Symphyotrichum ericoides var. ericoides, and Viola egglestonii. An exploration of Civil War-era herbarium specimens and historical documents illuminated the historical flora

Vascular Plant Flora of Stone Mountain Park, DeKalb County, Georgia, Based on Digitized Specimens in the University of Georgia Herbarium (GA)

ABSTRACT: Stone Mountain in DeKalb County, Georgia, is a large exposed granite monolith, 514 m (1,686 ft) above sea level and covering 230 ha (560 ac). This monadnock is located in the southwestern portion of Stone Mountain Park, comprising 1,300 ha (3,212 ac) owned by the state of Georgia. Recent specimen digitization efforts at the University of Georgia Herbarium (GA) have greatly facilitated capture of data from historic vouchers collected from this park. Based on these newly available data, the goals of this project were to (1) prepare a vouchered species list for the park, (2) produce a vegetation map
