Prospects Of Kenaf As An Alternative Field Crop In Virginia, Harbans L. Bhardwaj, Charles L. Webber Iii Oct 2005

Prospects Of Kenaf As An Alternative Field Crop In Virginia, Harbans L. Bhardwaj, Charles L. Webber Iii

Virginia Journal of Science

Kenaf (Hibiscus cannabinus L.), a warm-season annual plant, has shown potential as an alternate source of fiber in the United States. Although preliminary research has indicated feasibility of kenaf production in Virginia, production details are lacking. Field experiments were conducted during 1995 and 1996 to determine optimal row spacing and fertilizer needs, and to compare available kenaf cultivars. Although results indicated that differences in dry matter yields from four row spacings (30, 60, 90, and 120 cm) and four rates each of N, P, and K fertilizers (50, 100, 150, and 200 kg ha-1) were not …

Fish Consumption Patterns Of Populations In Vicinities Of Lake Kastoria And Lake Pamvotis, Greece, Eugene G. Maurakis, David V. Grimes, Dimitra Bobori Oct 2005

Fish Consumption Patterns Of Populations In Vicinities Of Lake Kastoria And Lake Pamvotis, Greece, Eugene G. Maurakis, David V. Grimes, Dimitra Bobori

Virginia Journal of Science

Objectives are to establish fish consumption patterns of populations in vicinities of two lakes (Kastoria and Pamvotis) in Greece for use in the assessment of risks associated with consumption of fishes in these agri-chemically impaired lakes. Parameters measured were demographics (i.e., gender, age, weight, education level, occupation, residency), freshwater fish eating frequency, species and sizes of fishes consumed, and fish consumption habits [i.e., quantity, parts, and preparation method). All annual mean site-specific consumption rates of the four gender-age class sub-populations surveyed in vicinity of Lake Kastoria (avg. range= 0.103-0.29 kg/day) exceed those of Greece (0.066 kg/day), EU (0.068 kg/day), Spain …

Phytoplankton Development Within Tidal Freshwater Regions Of Two Virginia Rivers, Harold G. Marshall, Lubomira Burchardt Jul 2005

Phytoplankton Development Within Tidal Freshwater Regions Of Two Virginia Rivers, Harold G. Marshall, Lubomira Burchardt

Virginia Journal of Science

Phytoplankton composition and the range of seasonal patterns of abundance are presented for the tidal freshwater regions in two Virginia rivers based on data accumulated monthly from 1986 through 1999. Diatoms dominated the flora during spring, summer, and fall, whereas, other taxonomic categories were more representative when the river flow rates decreased, allowing for a more stable water system and increased residency time within this tidal region during summer and early fall. This summer/fall period was associated with increased water temperatures, higher productivity rates and chlorophyll levels, increased total phytoplankton abundance and species diversity. The major components of the summer …

Bats Of Skydusky Hollow, Bland County, Virginia, Virgil Brack Jr., Richard J. Reynolds, Wil Orndorff, Joe Zokaites, Carol Zokaites Jul 2005

Bats Of Skydusky Hollow, Bland County, Virginia, Virgil Brack Jr., Richard J. Reynolds, Wil Orndorff, Joe Zokaites, Carol Zokaites

Virginia Journal of Science

During the period 22 November 1999 – 11 October 2001, winter hibernacula surveys, spring staging/autumn swarming surveys, and summer surveys for bats were completed in caves of Skydusky Hollow, Bland County, Virginia. During winter, 12 caves were entered and 16,185 bats counted: 235 Myotis sodalis (Indiana bat), 14,475 Myotis lucifugus (little brown myotis), 12 Myotis septentrionalis (northern myotis), 7 Myotis leibii (eastern small-footed myotis), 1,441 Pipistrellus subflavus (eastern pipistrelle), and 15 Eptesicus fuscus (big brown bat). Myotis sodalis hibernated in thermally stable areas of 7 -9 ̊C. The largest concentration of M. lucifugus (n = 4,280) hibernated in an area …

The Small Mammals Of Isle Of Wight County, Virginia, As Revealed By Pitfall Trapping, Robert K. Rose Jul 2005

The Small Mammals Of Isle Of Wight County, Virginia, As Revealed By Pitfall Trapping, Robert K. Rose

Virginia Journal of Science

In a study conducted in mid-winter, pitfall traps were used to assess the small mammal communities on 14 grids set in open habitats in Isle of Wight County in eastern Virginia. In all, 136 shrews of three species and 103 rodents of five species were trapped. Least shrews (n=110) comprised 46 percent of small mammals and 80 percent of shrews. Eastern harvest mice (n=62) were the most common rodents. Reproduction was detected only in pine voles and southern bog lemmings. The majority of small mammals of the region were trapped during this month-long study.

Comparison Of Aquatic Life Depicted In Illustrations And Plaster Casts Of The Punt Relief From The Temple Of Hatshepsut At Deir El-Bahari, Emily Lord, Eugene G. Maurakis Jan 2005

Comparison Of Aquatic Life Depicted In Illustrations And Plaster Casts Of The Punt Relief From The Temple Of Hatshepsut At Deir El-Bahari, Emily Lord, Eugene G. Maurakis

Virginia Journal of Science

The primary objective of this study is to document differences between image characteristics of two sources (illustrations in Naville, 1898; and images in the cast of the relief at Virginia Museum of Fine Arts (VMFA) of the Punt relief from the temple of Hatshepsut at Deir El-Bahri. Our second is to compare cast images to photographs of the original relief. Characteristics of 30 species in the illustrations were described and compared to descriptions of the corresponding 30 species photographed from the cast at VMFA. The number of differences and similarities were recorded for each pair of corresponding icons and used …
