Glacial Relict

Six populations of Great Plains Ladies’-tresses (Spiranthes magnicamporum Sheviak) have recently been discovered in three locations east of the lower Great Lakes region of Canada and the United States. The possible occurrence of S. cernua × magnicamporum hybrids was detected at one New York site. These discoveries are from both natural alvar and disturbed meadow and shore sites. The new records suggest that S. magnicamporum occurs more widely than was suspected previously, its presence perhaps masked by its similarity to the common S. cernua (L.) Richard. Eastern occurrences may represent a combination of post-glacial relict populations, responses to climate change, and the results of long-distance dispersal events. These range extensions constitute the most easterly known populations of S. magnicamporum in North America. They also represent new records for New York State (including Jefferson and St. Lawrence Counties) and for the City of Ottawa in Ontario.

The Third

Further study of the morphology of salivary gland chromosome complements within the range described for Prosimulium magnum showed the species to consist of three cytologically distinct populations. The first two forms are without sex chromosomes, (1) a form analogous to the species chromosomal standard, P. magnum, (2) a form which is differentiated by the fixed inversion IIS-25, but (3) the third form has cytological XcYc sex determination. In the Great Lakes region these three forms of the P. magnum complex and P. multidentatum are sympatric in three separate areas, Michigan, Southern Ontario, and Western New York State. Natural hybrids between the forms have so far been obtained only infrequently, and the known hybrids are described. Some chromosomal aspects of speciation are discussed in relation to the present observations on the species complex.

Fast Motion

An Alberta clipper moved over western New York state on 11-12 January 2004, producing snowfall amounts of up to 27 cm in portions of the region during a roughly 12-h period. In addition, lightning and thunder were reported. Such systems, known primarily for their fast motion and relatively dry nature, are not generally associated with significant snowfalls. A postmortem analysis of this event, following an ingredients-based methodology, revealed that as the weak low approached the lower Great Lakes, it came under the influence of coupled 300-hPa jets that produced enhanced divergence and significant upward vertical motion over western New York, resulting in the enhanced convective snowfall over the region for a limited time. Instability and possible enhancement via the Great Lakes are also investigated, which show that while there was at least modest instability over the region during the time of heavy snowfall, lake enhancement was unlikely.

Abstract This study presents a climatological analysis of the frequency and characteristics of lake-effect precipitation events that were initiated or enhanced by lakes within the New York State (NYS) Finger Lakes region for the 11 winters (October–March) from 1995/96 through 2005/06. Weather Surveillance Radar-1988 Doppler (WSR-88D) data from Binghamton, New York, were used to identify 125 lake-effect events. Events occurred as 1) a well-defined, isolated precipitation band over and downwind of a lake, 2) an enhancement of mesoscale lake-effect precipitation originating from Lake Ontario and extending southward over an individual Finger Lake, 3) a quasi-stationary mesoscale precipitation band positioned over a lake embedded within extensive regional precipitation from a synoptic weather system, or 4) a transition from one type to another. Results show that lake-effect precipitation routinely develops over lakes that are considerably smaller than lakes previously discussed as being associated with lake-effect precipitation, such as the Great Lakes. Lake-effect events occurred during each month (October–March) across the 11 winters studied and were identified in association with each of the six easternmost Finger Lakes examined in this study. The frequency of NYS Finger Lakes lake-effect events determined in the current investigation paired with subsequent analyses of the environmental conditions leading to these events will allow for 1) comparative analyses of necessary conditions for lake-effect development across a range of lake sizes (e.g., NYS Finger Lakes, Lake Champlain, Great Salt Lake, and Great Lakes) and 2) an informative examination of the connection between mesoscale processes and climate variability.

Vincetoxicum Rossicum

The alien invasive vine Vincetoxicum rossicum (Kleopow) Barbar. is problematic in the Lower Great Lakes Basin of North America. The lack of effective control strategies exacerbates the need for a better understanding of the growth and reproductive potential of V. rossicum. Thus, a 2-year field experiment was performed in a field site in 2003 and 2004 that was densely colonized by V. rossicum. Mean height of V. rossicum stems was 20% and 45% greater in naturally shaded plots compared with plots receiving full sun in 2003 and 2004, respectively. During the 2-year study, the density of stems 10 cm or taller averaged 134 stems·m–2, substantially greater than reported in previous field studies for this species. The high densities of stems and seedlings indicate that this field site may be near or at carrying capacity. Each stem produced, on average, 17 mature follicles with some stems producing as many as 100 follicles. Each follicle yielded an average of 15 seeds, each composed of an average of two viable embryos. A typical V. rossicum stand in this site produced as many as 54 000 seedlings·m–2 annually. More flowers (2400 flowers·m–2), follicles (2250 follicles·m–2), and total seeds (32 000 seeds·m–2) were produced in plots receiving intermediate light compared with plants in full sun (1650 flowers·m–2, 1600 follicles·m–2, and 25 000 seeds·m–2) or shaded (1600 flowers·m–2, 2000 follicles·m–2, and 28 000 seeds·m–2) plots. Seeds harvested from follicles in the low light plots were 41% more likely to be dormant than seeds collected from follicles in full sun plots. Seeds collected from plants in full sun plots had the lowest frequency (∼36%) of single embryo seeds and the highest frequency (∼64%) of multiple embryo seeds. These findings suggest that V. rossicum growth and reproductive output is influenced by light environment. While competitive strategies differ between the light environments, the decrease in viability and germination in shaded sites may not be large enough to affect population growth over multiple generations. The substantially greater growth and reproduction of V. rossicum reported in this study relative to previous research may explain the increasing abundance and range expansion of this species in many Lower Great Lakes regions of Ontario and New York State.
