Myotis soda/is hibernated in thermally stable areas of 7 9°C. The largest concentration of M lucifugus (n = 4,280) hibernated in an area that was cooler (6.5°C) than areas used by M soda/is. The remaining 6,300 M lucifugus hibernated at temperatures similar to, or slightly cooler than, temperatures used by M soda/is. Intra-cave (and possibly inter-cave) movements of M lucifugus and M soda/is during the season of hibernation concentrated bats in cooler areas of the caves. An unusually large concentration of P. subjlavus (n = 920) hibernated in Coon Cave in a warm (8.6 9.7°C), stable environment.

ABSTRACT 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 agrichemically 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 sitespecific 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 (0.104 kg/day), Portugal (0.159 kg/day), and the USEPA default value (0.054 kg/day) with two exceptions. Female consumption rates (0.087-0.103 kg/day) of Perea fluviatilis were below annual consumption rates of Spain and Portugal. Similarly, annual mean site-specific consumption rates of Anguilla anguilla and Cyprinus carpio by male (0.199-0.210 kg/day) and female adults (0.0960.157 kg/day) in vicinity of Lake Pamvotis exceeded those of Greece, EU, Spain, Portugal, and the USEP A default value. Survey results indicate bettereducated Greeks to be higher consumers offish; however, market availability appears to be a stronger determinant of food choice in comparison to health education. All populations in vicinities of both lakes preferred to eat fried fishes with one exception: grilled C. carpio from Lake Pamvotis was preferred by female and male adults.","PeriodicalId":23516,"journal":{"name":"Virginia journal of science","volume":"23 1","pages":"2"},"PeriodicalIF":0.0,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78128125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because fire impacts are poorly documented for herpetofaunal communities, we surveyed these stands in 1996 capturing 133 individuals of ten species during over 12,720 pitfall trapnights. We found no significant differences in relative abundance of Eastern Red-backed Salamanders (Plethodon cinereus) (P = 0.26), American Toads (Bufo americanus (P = 0.93), or all amphibians combined (P = 0.25) among unburned shelterwood stands and those treated with winter, spring, or summer burns. Three species of reptiles (Northern Fence Lizard [Sceloporus undulatus], Ground Skink [Scincella lateralis], and Southeastern Five-lined Skink [Eumeces inexpectatus]) combined were captured more frequently in burned versus unburned stands (P = 0.02). Based on a stepwise multiple regression model, Eastern Red-backed Salamander captures were more strongly influenced by landscape variables (P = 0.0320), including distance to permanent water and mesic (i.e., eastern-northern) aspects, than by fire treatments (P = 0.26).

Many associations are new to the United States (59), eastern United States (2), and Virginia (21 ); others extend the known distribution for those previously discovered. These reports contribute to the natural history of Virginia. INTRODUCTION This report describes collections of fungi identified on members of Poaceae in Virginia since 1995 when such collections were last described (Roane & Roane, 1994, 1996, 1997). Our objectives and procedures were described in those reports but will be summarized here. When a grass bearing fungi was studied, samples were incubated 2 4 days in a moist chamber, and all sporulating fungi were identified using manuals and monographs cited. Any fungus not listed by Farr et al. (1989) and Farr et al. (no date) was presumed to be a new record for the U.S.A. (NR, U), east of the Mississippi (NR, EU), or for Virginia (NR, V). Most of the fungi found have been described before on some host but a new host for a fungus implies a new record. No fungi were cultured and no attempt was made to establish or prove pathogenicity; only presence was established. Where material was adequate, a dried original specimen was preserved along with dried incubated material. An acquisition number was assigned to each collection; R00-10 refers to collection 10 of 2000. Plant Clinic numbers refer to the year and specimen number sent to the V.P.I. & S.U. Plant Clinic (ex.: PL Cl. 00-351). Since no fungi were cultured, in general, nomenclature of grasses and fungi presented by Farr et al. ( 1989) was followed. Later revisions of nomenclature are noted. Because of their frequency in the text, Roane and Roane will be cited as R & R, Shoemaker and Babcock as S & B, and Ellis and Ellis as E & E; these are listed completely in the references. Agropyron repens (L.) Beauv. Syn., Elytrigia repens (L.) Nevski quackgrass Ascomycotina: Claviceps purpurea (Fr.:Fr.) Tul., ergot. As stated previously (R & R, 1996), this fungus is widespread on A. repens; pseudosclerotia are readily observed on spikes approaching maturity. A specimen collected July 11, 2003 was received from a Fairfax Co. horse farm with the complaint that 30 horses were having neurological incoordination in early June, a time too early for the appearance of ergot peudosclerotia (R03-16, Pl.

We provide whole-body and skull keys to the 40 species that occur in this region. Baseline data for this work were collected during several studies conducted on Fort A. P. Hill, Caroline County. The intended audience includes interested naturalists, teachers, students, field biologists, and natural resource managers. INTRODUCTION These keys address all native land mammal species with geographic ranges that include Fort A. P. Hill (APH), Caroline County, Virginia, and nearby portions of the northern Coastal Plain. The species are representative of the mammal fauna of the northern Coastal Plain of Virginia. APH is centered approximately 77° 15' N and 38° 05' Wand is about 15 km east of the Fall Line-the boundary between the Piedmont and Coastal Plain physiographic regions. The current landscape consists of a mosaic of managed habitats that range from old field to mature hardwood forest (Mitchell and Roble, 1998; Bellows et al., 2001 c ). Baseline data for this work were collected as part of several studies conducted on APH ( e.g., Bellows et al., 1999; Bellows and Mitchell, 2000; Bellows et al., 2001 a, 2001 b ). Bellows et al. (2001 c) provide descriptions of the biologies, ecologies, and distributions of the 40 indigenous species we address herein, as well as descriptions of watershed drainages, climate, and habitats of the region. The presence of 38 mammal species on APH has been verified through direct observation or voucher specimens. One bat species, Myotis austroriparius, was identified by examination (ASB) and by photograph (David Webster, University of North Carolina at Wilmington). Mustelafrenata has not been captured or observed; however, APH is well within its geographic range (Hall, 1981) and its presence on the post is likely. The range of another species included in the keys, Blarina carolinensis, does not include APH, but it is found nearby to the north and east in the Northern Nec·k (Tate et al., 1980; Pagels and French, 1987). Native species Sigmodon hispidus and Ochrotomys nuttalli with range limits nearby the project area, as well as the known introduced species Rattus rattus, R. norvegicus, and Mus musculus, are not included herein.
