The parasitic cimicid swallow bug, Oeciacus vicarius, is the principal invertebrate vector for Buggy Creek virus (BCRV) and has also been associated with Venezuelan equine encephalitis virus. To help understand the spread of this vector, we experimentally measured the transmission of O. vicarius between groups (colonies) of its main host, the cliff swallow (Petrochelidonpyrrhonota), in the fiel...

This study aimed to evaluate the reaction of six grapevine rootstocks (MGT 101-14, Ritcher 110, Paulsen 1103, K 5BB, SO4, Salt creek) and two cultivars (Quebranta Torontel) three species root-knot nematode (Meloidogyne incognita, M. arenaria M.hapla). The experiment was performed as a completely randomized design with an 8 × 3 factorial scheme replicates per treatment. experimental unit in each...

The Upper Ordovician Utica Formation of the Appalachian Basin is a potential target for natural gas development. This black shale outcrops throughout the Mohawk Valley in Central New York State. The lower Flat Creek Member is characterized by E-W Mode 2 (strike-slip) fractures, bedparallel thrusts, and N-S Mode 1 (tensile) fractures. E-W fractures and dilational jogs host the majority of calcit...

Reconnaissance geologic investigations by I.L. Tailleur in 1968 noted the presence of widespread iron-oxide staining in creek beds in the Wulik River and Ikalukrok Creek drainages of the western Brooks Range. A brief examination of one of these creeks revealed the presence of weathered sulfide-bearing bedrock and stream sediments containing more than 10 percent lead (Tailleur, 1970). Tailleur n...

this study investigated the effects of sewage discharge on nutrient concentrations and bod5 levels in the coastal waters and sediments ofthe city of mombasa. the results indicated that nutrient concentrations in tudor, mtwapa and makupa creeks were elevated as compared to concentrations in gazi creek (mean ranges of 0.022-0.039mg/l, 0.038-0.163mg/l and 0.034-0.118mg/lphosphates, nitrates and am...

Continuous discharge from a combined sewer overflow (CSO) into a tidal wetland creek in the New York City urban area was analyzed to assess the extent of water quality degradation during both dry and wet weather. A combination of fecal indicator bacteria (FIB), total suspended solids, and dissolved metals were used to infer the presence of sewage and fecal pollution from the CSO discharge and t...

The Goshen Swamp, a fourth order blackwater creek in southeastern North Carolina, was clearcut of 130 acres of riparian and seasonally flooded forest in late May through September 1998. Downstream water quality had been monitored monthly for 212 years before the clearcut, during the clearcut, and for two years following the clearcut. The objective of this paper was to test the hypothesis that c...

each stream ecosystem may be impacted by land use and intensified human expansion. According to the fall macrobenthic results, nearly all sites saw an increase in %EPT, except for Massaponax 208 and Ni Route 1. Even though both Massaponax Creek and the Ni River are under EPA legal limits for phosphate and nitrate concentrations, the phosphate levels usually rose in summer on the Massaponax and ...

Glacial deposits in the southwestern Ahklun Mountains, southwestern Alaska, record two major glacier advances during the late Pleistocene. The Arolik Lake and Klak Creek glaciations took place during the early and late Wisconsin, respectively. During the Arolik Lake glaciation, outlet glaciers emanated from an ice cap centered over the central portion of the Ahklun Mountains and expanded beyond...
