AbstractA major pre-Wisconsinan glacial event is the only possible source of the lower till on Nantucket Island, Massachusetts. The till occurs near the late Wisconsinan drift border and below fossiliferous marine beds of oxygen-isotope stage 5 (Sangamonian) age. It is considered to be Illinoian in age, but the evidence is tenuous. The till is correlated with the lower till of New England, and its presence supports the view that the New England upper and lower tills represent two glaciations. The pre-Wisconsinan (lower) till in New England may correlate with older tills elsewhere in the northeastern United States and in southeastern Canada that are considered to be early Wisconsinan or older in age.

The Atlantic sea scallop (Placopecten magellanicus) is harvested in the waters off the coast of the northeastern United States and Canada by vessels from both countries. The Atlantic sea scallop fishery has been an important fishery in the Northeastern U.S. in recent decades. This is particularly true for New England where, during the quarter-century ending in 1976, over 10 percent of the value of all fish and shellfish landed was attributable to the harvest of sea scallops.

Produce safety and climate change are two overlapping risks that face vegetable producers in the northeastern United States. Because of recent public health outbreaks (and subsequent litigation) traced back to fresh produce, food safety hazard identification and risk mitigation has become the focus of significant regulatory changes in the United States (FDA 2015)

Abstract Fault plane solutions for eight earthquakes occurring in the northeastern United States have been determined using P-wave first motions and a computer algorithm for picking all valid solutions. The predominant mechanism in the area is thrust faulting, however the direction of the P axis is not consistent throughout the entire area. In central New England (Maine-New Hampshire), the P axis trends nearly E-W. In southeastern New England, the P axis trends N-S to NE-SW. In the Adirondacks region of New York, the P axis trends NE-SW as previously reported by Yang and Aggarwal (1981). Although the stress distribution appears to be complicated, as in the Central United States (Street et al., 1974), an underlying E-W compressive stress may exist in the New England area. These small earthquakes may represent the response to local stress concentrations.

Morphological Differences

We compared the variation in mitochondrial DNA among species of cottontail rabbits in the northeastern United States to (i) assess the effects of historic transplants of eastern cottontails (Sylvilagus floridanus) on subspecific status, (ii) examine the extent of hybridization between invading eastern cottontails and declining populations of endemic New England cottontails (S. transitionalis), and (iii) evaluate the recent reclassification of S. transitionalis into two sister-species, New England cottontail and Appalachian cottontail (S. obscurus). Sequence variation in the tRNAPro and the first 310 base pairs of the control region supported a separation of the two species S. floridanus and S. transitionalis/S. obscurus. However, geographic structuring of haplotypes was not detected for either group. Genetic similarity among populations of S. floridanus indicated that subspecific designations are not warranted for this species in the northeastern United States. Comparisons of sequence information from populations of S. transitionalis/S. obscurus that were never sympatric (Maine), recently sympatric (New Hampshire), or sympatric with eastern cottontails since the last glaciation of eastern North America (Virginia, West Virginia, Maryland, North Carolina) indicated that hybridization is not occurring between eastern cottontails and New England or Appalachian cottontails. Limited variation in mitochondrial DNA does not support the recent reclassification of S. transitionalis into sister-species. However, karyotypic and morphological differences between northern and southern populations should be considered during any efforts to restore declining populations of this species.

Successful Establishment

Abstract Characteristics of and requirements for successful establishment and operation of fuelwood cooperatives were assessed by evaluating nine currently or recently operating New England fuelwood cooperatives. Three types of cooperatives were identified—consumer, processing, and producer. The importance of maximizing local member-patron participation in all facets of cooperative action and of restricting government and professional forestry involvement to educational and forestry assistance are illustrated. Churches are identified as a potential source of assistance in attempts to establish and operate fuelwood cooperatives. North. J. Appl. For. 3:137-139, Dec. 1986.
