Oriental bittersweet (Celastrus orbiculatus) is an invasive, exotic, woody vine introduced to North America in the mid- to late 1800s from East Asia. This vine is problematic because it can kill trees through competition and mechanical stress, which in turn creates problems for tree care professionals in utility right-of-way and other hazard tree work. Oriental bittersweet is becoming more prevalent as a problem throughout the eastern United States. Two manipulative field experiments were conducted across the Hudson Valley in New York State to test the timing of cutting and glyphosate herbicide effects on large vine mortality. While results from the first year indicated that herbicides were needed with vine cutting to achieve high mortality rates, this was not true with second year results. Cutting vines without herbicides produce the same, high rate of mortality of oriental bittersweet vines after the second year (>90% kill) as cut-stump treatments with herbicides. It may be important that high kill of cut vines is related to large vine size, and that stumps were in forest shade. Herbicides may not be necessary to kill cut-stump methods to kill oriental bittersweet vines that have a minimum stem diameter >2–3 cm and are growing in areas where stumps are in shade.

Glacial erratics belonging to the Rickard Hill facies (RHF) of the Saugerties Member of the Schoharie Formation (upper Emsian: Lower Devonian) occur scattered throughout the Piedmont of northern New Jersey and Lower Hudson Valley of New York. These RHF glacial erratics contain an assemblage of trilobites belonging to: Anchiopella anchiops, Burtonops cristatus, Calymene platys, Terataspis grandis, cf. Trypaulites sp. and cf. Coniproetus sp. This RHF glacial erratic trilobite assemblage consists predominately of disarticulated cephala and pygidia that were originally preserved as part of a localized, third-order eustatic sea level lag deposit in the Helderberg Mountains region of central New York State and subsequently transported in glacially plucked blocks by the Hudson-Champlain Lobe of the Laurentide Ice Sheet southward into New Jersey. Physical and chemical weathering during glacial erosion, transportation and deposition of the RHF glacial erratics has revealed some anatomical features of these trilobites in high detail along with other invertebrates. This unique sequence of weathering reveals additional characteristics that bear upon issues of bathymetric controls on upper Schoharie Formation lithology, trilobite faunal abundance and taphonomy during the upper Emsian (Lower Devonian) of eastern New York State.

Arriving in the colony of New York in 1774 from England, Ann Lee and her eight followers set about creating a model communal society in what would become the United States. Officially known as the United Society of Believers in Christ’s Second Appearing, the Shakers believed in Christ’s imminent return. Their support of pacifism, near equality between the sexes that allowed women to take on leadership roles, and perfectionism set them apart from most Americans. Within a decade, they had begun creating a Kingdom of Heaven on Earth through their worship, work ethic, and construction of orderly villages with buildings and furniture meant to reinforce religious belief and shape and control behavior. From humble beginnings, the sect created a total of twenty-two communities beginning in the 1780s, spreading from Maine to Indiana and as far south as Georgia and Florida, though these latter two sites and the one in Indiana were short lived. During periods of religious revivalism in the United States in the late 18th and early19th centuries, the Shakers attracted hundreds of converts who gave up their worldly possessions to live celibate, communal lives. After a peak population of over three thousand in the1840s, the Shakers have dwindled to just three members inhabiting the only surviving living community of Sabbathday Lake, near New Gloucester, Maine. The Shakers’ demographic and economic success over several decades left a legacy of buildings at numerous locations throughout the eastern United States. Some of these villages have become museum sites, most notably Hancock, Massachusetts; Mount Lebanon, New York; Canterbury, New Hampshire; and Pleasant Hill and South Union, both in Kentucky. Other Shaker buildings remain as private residences and parts of retirement communities and state prisons. In many ways, Shaker architecture reflects contemporary regional vernacular building practices, such as the closely spaced anchor bents in the framing of the earliest meetinghouses in Connecticut, New Hampshire, Maine, Massachusetts, and eastern New York State, and the rather grand masonry structures of the dwelling houses and trustees’ offices in Kentucky. The linear arrangement of buildings, their large size, and separate entrances for men and women distinguished Shaker buildings from those of the outside world, though stylistically they appeared much like non-Shaker buildings. The Shakers organized building interiors to use space efficiently with many built-in cabinets and drawers, installed pegboards on walls for storage and to help keep floors clear for cleaning, and included separate staircases to demarcate men’s and women’s areas. The buildings, especially the meetinghouses and dwelling houses, reminded Shakers of their commitment to their faith and to their distinctive way of living and encouraged them to “put their hands to work and their hearts to God,” a saying attributed to Ann Lee. Nevertheless, the Shakers were not immune from influences from the outside world. They needed to interact with outsiders to encourage the economic success of their villages and to attract converts. As their population shrank in the latter half of the 19th century, they turned increasingly to hired help to assist with building construction and other aspects of daily life. The Shakers also embraced stylistic changes in architecture and furniture; their buildings of the late 19th and early 20th centuries reflect these influences with added ornamentation inside and out, as well as embellished furnishings either made by the Shakers or purchased from non-Shaker furniture makers. Rather than undercut any appreciation of the simple style for which the Shakers are best known, these changes show the group as always practical and responsive to changes in mainstream society.

Abstract Nonindustrial private forestlands (NIPFs) account for a majority of the forested working landscape in the eastern United States. Throughout the United States, NIPF average ownership sizes continue to decline. Smaller parcel sizes create declining economies of scale for forest managersand timber harvesters, threatening the viability of the forested working landscape and, in turn, wood supply. This study documents the parcelization of NIPF holdings in a central New York State county during the last 25 years of the 20th century. The findings indicate the average parcel sizeof NIPFs decreased from 36 to 24 ac over the study period, despite a decline in population in the county. Although average parcel size is declining, a large percentage of the rural forestland remains in acreage classes suitable for forest management, as long as the forest products industrycan adapt to changes on the landscape.

<p>Uncertainties on the radiometric ages of Devonian stage boundaries are currently on the order of several millions of years. A cyclostratigraphic approach is the foremost way forward to improve the Devonian geological time scale. To do so requires well-preserved continuous records, as well as reliable paleoclimatic proxies.  The NY Route 199 section, from Kingston, in the Hudson Valley of eastern New York, is a road cut outcrop, which exposes most of the Schoharie Formation. It corresponds to the upper portion of the Emsian Stage (upper Lower Devonian, ~400 to ~394 Ma), with essentially continuous deposition. The lithology consists of a mixed siliciclastic-carbonate succession with overall increasing carbonate upsection, showing various degrees of bioturbation (traces includes primarily Zoophycos, Planolites and Chondrites); colors range from white to beige, brown or dark grey. The quality of most of the outcrop is so remarkable that the color variations by themselves permit recognition of Milankovitch cycles, with prominent bundles of light and dark beds. One type of cycle expression is represented by a succession of about six darker beds nested between lighter beds, which is interpreted as six precession cycles within a short eccentricity cycle (precession in the Devonian was ~17 kyr).</p><p>Samples were collected every 2 cm through 38 m of the section for magnetic susceptibility measurements. On top of these measurements, we provide elemental geochemistry, carbon isotopes and hysteresis measurements (every 50 cm) to constrain the depositional setting and the diagenesis. Hysteresis measurements show that despite being remagnetized (throughout the Appalachians, these Paleozoic rock sequences are all remagnetized during the Variscan-Alleghenian Orogeny), the magnetic susceptibility reflects depositional information. The geochemistry and carbon isotopes give insight into the occurrence of oxic/reducing conditions and detrital inputs. Milankovitch cycles are visible on the outcrop and in the magnetic susceptibility record, allowing a precise floating timescale framework to be constructed for this interval.</p>

The moss Ptychomitrium serratum (C. Müll. Hal. ex Schimp.) Besch., is native to Mexico and parts of western Texas and southern New Mexico, and it is a rare adventive in the area from East Texas and Louisiana to Missouri, Tennessee, South Carolina, and northward to locations near the coast in New York State and Massachusetts. In the adventive part of this calcicole’s range, all collections are from the past 50 years. Concrete, mortar, and rarely asphalt shingle are its only known substrata in this region, which contrasts sharply with its common occurrence on limestone in the native portion of its range. These observations indicate recent, perhaps on-going, immigration into the eastern United States and dispersal from established populations in this region. This monoicous moss commonly produces spores, which are its primary means of spread. Given the low density occurrences in the adventive portion of the range of P. serratum, dispersal may be generally northeastward from Mexico – Texas – New Mexico, following northeastward storm tracks in the southern and eastern United States. The apparently recent spread of this moss does not show obvious reliance on any direct human activity.

Geomagnetic variation data for all available stations in eastern North America are presented here in the form of induction arrow maps at periods of 6, 20, and 64 min. The region is subdivided on the basis of the induction patterns revealed by these maps.The near-coastal stations are influenced by conductivity contrasts associated with the continent – ocean water interface, although the considerable variation in amplitude and in inland persistence of the coast effect reflects variations in the conductivity contrast across this transition. The predominantly southward-pointing arrows of the shield areas appear to reflect their source fields rather than subsurface conductivity. This pattern is disrupted by the high conductivity associated with the anomalously high crustal temperatures in the vicinity of the White Mountain heat flow anomaly and is terminated abruptly in the south by a well-defined reversal through northern New York State. We suggest that the conductivity boundary defined by this line of reversal continues southward to join a similar boundary observed near the Ohio – West Virginia border. These boundaries, with the crystalline Appalachians to the east, bound a segment of the crust (or upper lithosphere) whose conductivity structure is quite distinct from its surroundings.This region lies within the Central Geophysical Province of Diment et al.; however, if the poorly defined western and northern boundaries of that province are replaced by the line of reversal the two regions coincide. Some tentative models for its origins are discussed. We also suggest that the subdued geomagnetic coast effect in Virginia may be related to the extensive overthrusting of Paleozoic sediments by the crystalline Appalachians, which has been proposed on the basis of deep seismic reflection studies further to the south (Cook et al.).
