Bulletin The CBA Bulletin is issued quarterly (in theory As Editor of the Bulletin, I consider that availability and openness to members are in March, June, September, and December) and sent to all CBA members. very important. To help myself in reaching that goal, I created an Editor’s Page (www.umce.ca/cours/martin/CBA_ABC_Editor/) where I want to explain what the Information for submitting texts Bulletin is made of. This web page may be reached through the CBA web site as All members are welcome to submit texts in the well. All aspects of the Bulletin will be treated, from editorial policy to how to write form of papers, reviews, comments, essays, requests, or anything related to botany or a book review. These informations are updated regularly and should help, I hope, botanists. Any medium is acceptable for any members to learn how to contribute to their Bulletin.

    Vaccinium Macrocarpon Ait. Family: Ericaceae

    Cultivation Notes No. 54 THE RHODE ISLAND WILD PLANT SOCIETY Winter 2011 Cranberry – Vaccinium macrocarpon Ait. Family: Ericaceae Cranberry: a Native Jewel By Linda Lapin Cranberries are indispensable for the winter holidays. Tradition brings them to our holiday turkey dinners, and who doesn't have a linen table cloth with at least a little red stain on it from a wayward serving of cranberry sauce? This Rhode Island native berry may be a little smaller than the commercially grown cranberry varieties but is just as tasty when used in sauces, jellies, sweet breads, pies and stuffings. Cranberry, Vaccinium macrocarpon, grows wild in Rhode Island. Its native range extends from the East Coast to the Central U. S. and Canada, and from Southern Canada in the north to the Appalachians in the south. It is usually found in acid bogs growing in sphagnum along with other ericaceae such as highbush blueberry and black huckleberry. It grows in company with sheep laurel, leatherleaf, pitcher plants, sundews, and saplings of white cedar and red maple. Look for it in the Great Swamp or Diamond Bog. Cranberry was once called crane berry, because the flower resembles the look of a crane’s head and neck with a long sharp beak. Cranes were also observed wading the bogs gobbling up the berries. Other common names are black cranberry, low cranberry, trailing swamp cranberry, bear berry, and bounce berry. (Cranberries really are the best bouncing fruit I know.) A related species is small cranberry (Vaccinium oxycoccus), which is even smaller and cuter. The plant is a low-growing, evergreen perennial with trailing, wiry stems.

The Chinook, for example, traded dried cranberries with the English vessel Ruby in 1795 and at Thanksgiving in 1805 Lewis and Clark dined on venison, ducks, geese, and small cranberry sauce from fruit brought by Chinook women (McDonald 1966; Lewis and Clark 1965). Because the small cranberry can grow in association with large cranberry (Vaccinium macrocarpon) in the Great Lakes region, northeastern USA and southeastern Canada (Boniello 1993; Roger Latham pers. comm. 2009) it is possible that the Pilgrims of Plymouth were introduced to both edible Small cranberries growing in a bog on the western Olympic species by the Wampanoag.

    "How To" Tips on Hedge and Tree Maintenance

    How To Tips Landscaping Suggestions for Shady Yards Part of what makes Greenbelt so special is its abundant trees. However our wealth of tree cover can also present some challenges in yard landscaping. If your yard has partial to full shade this information sheet will provide some of the landscaping options for a beautiful GHI yard. Grass options for shady yards If your yard has at least partial sun during the summer months you can probably maintain a healthy grass layer by following these tips. Choose the right seed type. Mixes with Red Fescue and Perennial Rye tend to do better in shady yards. Make sure to read the label on any seed mix you buy to make sure what type of seed you are buying. Fertilize and aerate your yard in the spring. Don’t mow too short. Let the grass grow to 3-3.5 inches in shady areas. Short cutting will overstress the plants. See “How to Tips Establishing a Great Lawn” for more details. Leaving the turf behind If your yard is full shade during the summer, growing grass is probably not an option. Consider yourself lucky. This means you don’t need to worry about mowing. But you do need to cover bare spots to prevent erosion. Don’t worry there are options for heavily shaded yards that are both beautiful and manageable. Ground Moss Ground moss plants are a low-growing, no-maintenance grass alternative. Some mosses, massed together, give a smooth appearance, including rock cap mosses (Dicranum), fern mosses (Thuidium) and the aptly named "cushion" mosses (Leucobryum).

Schmitz1 and Vera L. S. Valente2 1 Universidade Federal da Integração-Latino-Americana, Foz do Iguaçu, PR, Brazil; [email protected] 2 Programa de Pós-Graduação em Genética e Biologia Molecular, Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil; [email protected] Abstract Diptera is a megadiverse order, reaching its peak of diversity in Neotropics, although our knowledge of dipteran fauna of this region is grossly deficient. This applies even for the most studied families, as Drosophilidae. Despite its position of evidence, most aspects of the biology of these insects are still poorly understood, especially those linked to natural communities. Field studies on drosophilids are highly biased to fruit-breeders species. Flower-breeding drosophilids, however, are worldwide distributed, especially in tropical regions, although being mostly neglected. The present paper shows results of a biodiversity inventory of flower-breeding drosophilids carried out in Brazil, based on samples of 125 plant species, from 47 families. Drosophilids were found in flowers of 56 plant species, of 18 families. The fauna discovered showed to be highly unknown, comprising 28 species, 12 of them (>40%) still undescribed.

    The Effects of Fire Frequency on the Reproductive Success of Buzz-Pollinated Blueberry (Vaccinium Pallidum) and Huckleberry (Gaylussacia Baccata) Kaitlyn E

    The effects of fire frequency on the reproductive success of buzz-pollinated blueberry (Vaccinium pallidum) and huckleberry (Gaylussacia baccata) Kaitlyn E. Irwin (University of Scranton, Scranton PA 18510), Claire O’Kane (Cornell University, Ithaca NY 14850), Timothy Green (Brookhaven National Laboratory, Upton NY 11973), and Nicole Miller-Struttmann (Webster University, St. Louis, MO 63119) Abstract Fire suppression has dramatically modified wildlands in the United States. Following forest fires, the release of nutrients triggers flowering, seed germination, and the creation of bee nesting habitats. Since fire suppression prevents this regeneration from occurring, pollination services may be diminished as well. The focus of our project is to determine the effects of fire on the reproductive success of two buzz- pollinated plant species, blueberry (Vaccinium pallidum) and huckleberry (Gaylussacia baccata). Our prediction is that fire will increase the reproductive success of these plant species through enhanced bee abundance and diversity. To test this, we quantified flower production bee activity along a fire gradient at Brookhaven National Lab. We examined pollination success (the number and diversity of pollen grains on stigmas) and fruiting success. Our results indicate that flower production, bee activity, and plant reproductive success were influenced by fire frequency. However, our results did not support our hypothesis, and instead showed that fire has a significantly negative effect on huckleberry and blueberry reproductive success. Introduction Results • Fire suppression turns pine habitats into • Bee density was directly correlated with flower abundance (F1,1 = 161.28, P = 0.050; Fig. 2A) and indirectly closed-canopy forests dominated by oaks and correlated with fire frequency (F1,1 = 18.59, P = 0.15; Fig.

    AN ABSTRACT OF THE THESIS OF Jan Alan Henderson for theDoctor of Philosophy inPlant Ecology (Botany) presented on 9 7/' / 7? Title: Composition, Distribution and Succession of Subal ne Meadows in Mount Rainier National Park Abstract approved: --' Dr. W. W. Chilcote In 1970 a phytoscxiological reconnaissance consisting of 135 plots in the Subalpine Meadow Zone was made. These samples were sorted using an association table and several Alpine Zone and very early seral communities were set aside, An additional hundred plots taken by M. 3. Hamann were incorporated with these and compiled in another association table and com- bined in a two-dimensional ordination.This analysis yielded 18 major and 16 minor described community types which were clustered into five vegetation types. A key to the vegetation and community types is also presented. Soil moisture and temperature data were taken during 1971 and 1972 and are used to help characterize selected important communities. Soil moistures did not drop much during either season, although differences between corn- munities are apparent. The difference in temperatures (of the top 2 cm of soil) of the same selected communities were more striking. The Festuca domi- nated communities experienced soil temperatures over350C, while maximum temperatures in other communities rarely ranged over 20 C Low mght- time temperatures were relatively similar from conimumty to commumty, ranging from near freezing to about + 5° C. Several successional patterns were uncovered. In general the com- munities in the Low-Herbaceous Vegetation Type are early seral and are replaced by members of the Wet-Sedge, Lush-Herbaceous and the Dry-Grass Vegetation Types.

    J. Agric. Food Chem. 2004, 52, 7039−7044 7039 Comparison of Anthocyanin Pigment and Other Phenolic Compounds of Vaccinium membranaceum and Vaccinium ovatum Native to the Pacific Northwest of North America JUNGMIN LEE,† CHAD E. FINN,§ AND RONALD E. WROLSTAD*,† Department of Food Science, Oregon State University, Corvallis, Oregon 97331, and Northwest Center for Small Fruit Research, U.S. Department of Agriculture-Agricultural Research Service, HCRL, 3420 NW Orchard Avenue, Corvallis, Oregon 97330 Two huckleberry species, Vaccinium membranaceum and Vaccinium ovatum, native to Pacific Northwestern North America, were evaluated for their total, and individual, anthocyanin and polyphenolic compositions. Vaccinium ovatum had greater total anthocyanin (ACY), total phenolics (TP), oxygen radical absorbing capacity (ORAC), and ferric reducing antioxidant potential (FRAP) than did V. membranaceum. The pH and °Brix were also higher in V. ovatum. Berry extracts from each species were separated into three different fractionssanthocyanin, polyphenolic, and sugar/ acidsby solid-phase extraction. The anthocyanin fractions of each species had the highest amount of ACY, TP, and antioxidant activity. Each species contained 15 anthocyanins (galactoside, glucoside, and arabinoside of delphinidin, cyanidin, petunidin, peonidin, and malvidin) but in different proportions. Their anthocyanin profiles were similar by high-performance liquid chromatography with photodiode array detection (LC-DAD) and high-performance liquid chromatography with photodiode array and mass spectrometry detections (LC-DAD-MS). Each species had a different polyphenolic profile. The polyphenolics of both species were mainly composed of cinnamic acid derivatives and flavonol glycosides. The major polyphenolic compound in V. membranaceum was neochlorogenic acid, and in V. ovatum, chlorogenic acid.
