Detailed Work

The present study is one of the unpublished research projects which are known to have been conducted in New England and in Eastern Canada under the guidance of the late Richard J. LOUGEE, long-time professor of Geomorphology at Clark University. Over a number of years, this writer has worked in close relationship with Lougee and much evidence in the field was studied together. It is believed that here has been recorded a most detailed work of surveying, and this undoubtedly accounts for the somewhat exceptional results that will be presented. The area selected for this study (about 80% of it is woodland) is located in the highlands of Central Massachusetts in Worcester County, about twenty miles (32 kilo-meters) northwest of the city of Worcester. It consists of the valley of the Otter River draining north, and of a small portion of the East Branch of the Ware River draining south. Since completion of this study, parts of the low area which held the ancient glacial lakes have been flooded to become water reservoirs. That proglacial lakes, though temporary they may have been, once submerged much of the area under study, is shown by an abundance of deltas, kames, eskers and deltaic kames terraces. It is believed that all of these were built under water in such lakes. Other features, such as kettle-holes and glacial outlets, especially ice-marginal channels cut diagonally down the slope, have also been studied. By plotting on a profile of the most characteristic elevations (often carefully surveyed), it is possible to find the water planes of ancient proglacial lakes. To this must be added experiments conducted in a sedimentation tank as also measurements of both the imbrication of cobbles in eskers and the « smoothness indexes » of such stones and pebbles, using A. Cailleux' methods. Thus were obtained results which tend to show that : 1- the area under study probably was in a deep interlobate space created between the Connecticut Valley lobe to the west and the Boston Basin lobe to the east ; 2— ice-marginal channels are an indication of the existence of a thick, fast-retreating ice border ; 3- an isostatic balance restored itself by sometimes quick and strong adjustments of the crust of the earth ; 4— an early upwarping, made up of various zones of tilting articulated on hinge lines, has been referred to as Hubbard Uplift and is the earliest known in the post-Glacial history of New England.

Early Developmental

One hundred six cases of phenylketonuria have been surveyed in 11 institutions in New England and Eastern Canada. Data not previously available (and of some degree of uncertainty as to reliability) are presented as to the ages at which patients with phenylketonuria achieve the ability to sit unsupported, to walk independently, and to say recognizable words. A small number of patients achieve these steps at reasonably near the normal age and the degree of variability is such that early developmental timetables should not be overemphasized in interpreting possible effects of any treatment of the disease. Both eczema and seizures are proportionately more frequent in severely retarded patients with phenylketonuria than in those with lesser degrees of intellectual defect. If present at the time an experimental treatment is instituted, they would provide more objective evidence of possible benefit. Electroencephalograms were abnormal in 79% of patients for whom tracings were available and would provide one means of evaluating plans of treatment even in the absence of seizures. While the majority of these patients have blue eyes and blond hair, there is enough evidence to suggest a tendency to darkening of the hair with age that this also should be used with caution in evaluation of treatment. Frequencies of various neurologic manifestations are presented, including unusual hand posturing, tremor, hyperreflexia, clonus and spasticity. These are all variable enough that a reasonably positive diagnosis [See FIG. 2. in Source Pdf.] by physical examination is not possible, and further, they are not well adapted to evaluation of treatment. The distribution of intelligence quotients in patients with phenylketonuria appears to follow a continuous curve and to include a small number of persons with borderline normal or better intelligence. In assessing the effect of any treatment, it is unwarranted to ascribe to that treatment the attainment of borderline normal intellectual levels that may be reached by small numbers of patients, especially if originally tested in infancy or early childhood. The effect of any therapy can be adequately evaluated only by comparing changes in a number of treated patients with phenylketonuria, with changes in comparable control patients, selected on the basis of intelligence, age, physical accomplishments, and status with respect to hair color, eczema, convulsive seizures and electroencephalographic findings.

Dramatic Rise

AbstractSediment cores collected along a transect in Crooked Pond, southeastern Massachusetts, provide evidence of water-level changes between 15,000 cal yr B.P. and present. The extent of fine-grained, detrital, organic accumulation in the basin, inferred from sediment and pollen stratigraphies, varied over time and indicates low water levels between 11,200 and 8000 cal yr B.P. and from ca. 5300 to 3200 cal yr B.P. This history is consistent with the paleohydrology records from nearby Makepeace Cedar Swamp and other sites from New England and eastern Canada and with temporal patterns of regional changes in effective soil moisture inferred from pollen data. The similarities among these records indicate that (1) regional conditions were drier than today when white pine (Pinus strobus) grew abundantly in southern New England (11,200 to 9500 cal yr B.P.); (2) higher moisture levels existed between 8000 and 5500 cal yr B.P., possibly caused by increased meridonal circulation as the influence of the Laurentide ice sheet waned; and (3) drier conditions possibly contributed to the regional decline in hemlock (Tsuga) abundances at 5300 cal yr B.P. Although sea-level rise may have been an influence, moist climatic conditions during the late Holocene were the primary reason for a dramatic rise in water-table elevations.

Daphnia Catawba

Despite the importance of Daphnia in freshwater zooplankton assemblages, species boundaries in the genus are unclear. This study verifies the taxonomic validity of D. catawba by establishing its genetic divergence from other species of Daphnia that occur in eastern North America. In addition, it reveals the presence of a second, closely allied species, D. minnehaha, which had previously been placed in synonomy with D. pulex. Daphnia catawba and D. minnehaha share a preference for acidic habitats and are restricted to the deciduous and boreal forest regions of the eastern portion of the continent, where D. catawba is restricted to lakes, while D. minnehaha occurs in ponds. Both species reproduce by cyclic parthenogenesis and, based on the extent of their allozyme differentiation, last had a common ancestor more than 7 million years ago. Populations of D. minnehaha fall into two genetic clades; those from the Great Lakes watershed are morphologically divergent and have much lower levels of genotypic diversity than those from eastern Canada and the New England states.

Colpomenia Peregrina

From May to October 2017 seaweeds were identified in the field and laboratory from 20 sites around Brier Island, Nova Scotia. While most sites were intertidal rocky shores, there were one small salt marsh and one eelgrass bed included in the study, and some subtidal sampling was conducted utilizing SCUBA and snorkeling. The Brier Island seaweeds comprised 152 species and varieties of which 62 were Rhodophyta, 44 were Chlorophyta, 44 were Phaeophyceae, and two species were Xanthophyceae. Three species were new records for eastern Canada: Colaconema bonne- maisoniae, C. endophyticum, and Elachista stellaris, all were pre- viously recorded from New England. The flora included eight non- native species of which Colpomenia peregrina and Bonnemaisonia hami- fera (both gametophytic and tetrasporophytic stages) were abundant at two or more sites, and the invasive Codium fragile subsp. fragile was recorded based on a single drift specimen. With 150 species and varieties of seaweeds, Brier Island has the highest species richness of a limited area of eastern Canada. The Cheney floristic index at 2.4 is higher than comparable areas, and suggests that many additional brown algae remain to be found.Keywords: Chlorophyta, Colaconema, Bay of Fundy, Brier Island, Phaeophyceae, Rhodophyta, seaweeds

Six grey, Halichoerus grypus, and 12 harp, Phoca groenlandica, seals were inoculated intratracheally with lung homogenate containing influenza virus A/seal/Mass/1/80 and mycoplasma from harbor seals, Phoca vitulina, which had died in an epizootic of pneumonia. The grey seals were refractory to infection, whereas some of the harp seals developed mild pneumonia. Virus was recovered from 4 of 10 harp seals necropsied, and antibodies were produced in 2 survivors. The mycoplasma given alone to 2 grey seals did not replicate or produce infection and was recovered from only 1 of 12 harp seals inoculated. We examined 99 grey, 102 harp, 14 harbor, and 7 hooded seals (Cystophora cristata) from eastern Canada and found antibodies to avian influenza A/seal/Mass/1/80 in 3 adult male grey seals from Sable Island, N.S.; this virus is apparently adaptable to other seal species. Related forms of the virus are highly suspect as the cause of past epizootics, and one is currently responsible for a new outbreak of pneumonia in New England harbor seals.

Heavy Infestation

Abstract LeGresley, M. M., Martin, J. L., McCurdy, P., Thorpe, B., and Chang, B. D. 2008. Non-indigenous tunicate species in the Bay of Fundy, eastern Canada. – ICES Journal of Marine Science, 65: 770–774. The frequency of fouling tunicates is increasing in Atlantic Canada and along the New England coast of the US. Canadian shellfish industries in the Gulf of St Lawrence and along the south shore of Nova Scotia have been affected by the heavy infestation of fouling tunicates. Because little research on tunicates has been conducted in the Bay of Fundy, a Canadian monitoring programme was established to look for the non-indigenous tunicates Ciona intestinalis, Botryllus schlosseri, Didemnum sp. A, Botrylloides violaceus, and Styela clava, in southwest New Brunswick. Collectors were deployed at 11 stations in May/June 2006. Some were retrieved in August 2006; others remained until November of the same year. Ciona intestinalis had established at three survey sites, St Andrews Harbour, St Andrews Biological Station, and Fairhaven, Deer Island, but the heaviest infestation was in the Lime Kiln Bay–Charlie Cove area. The greatest settlement of B. schlosseri was at the Dipper Harbour site, with minimal settlements in St Andrews Harbour and Harbour de Loutre. The other species of interest were not detected during the survey.
