A Ypt/Rab Effector Complex Containing The Sec1 Homolog Vps33p Is Required For Homotypic Vacuole Fusion, Darren F. Seals, Gary Eitzen, Nathan Margolis, William T. Wickner, Albert Price

Dartmouth Scholarship

Yeast vacuoles undergo priming, docking, and homotypic fusion, although little has been known of the connections between these reactions. Vacuole-associated Vam2p and Vam6p (Vam2/6p) are components of a 65S complex containing SNARE proteins. Upon priming by Sec18p/NSF and ATP, Vam2/6p is released as a 38S subcomplex that binds Ypt7p to initiate docking. We now report that the 38S complex consists of both Vam2/6p and the class C Vps proteins [Reider, S. E. and Emr, S. D. (1997) Mol. Biol. Cell 8, 2307-2327]. This complex includes Vps33p, a member of the Sec1 family of proteins that bind t-SNAREs. We term this …

Biological Implications Of A Discrete Mathematical Model For Collagen Deposition And Alignment In Dermal Wound Repair, J. C. Dallon, J. A. Sherratt, P. K. Maini, M. W. Ferguson

Faculty Publications

We develop a novel mathematical model for collagen deposition and alignment during dermal wound healing. We focus on the interactions between fibroblasts, modelled as discrete entities, and a continuous extracellular matrix composed of collagen and a fibrin based blood clot. There are four basic interactions assumed in the model: fibroblasts orient the collagen matrix, fibroblasts produce and degrade collagen and fibrin and the matrix directs the fibroblasts and determines the speed of the cells. Several factors which influence the alignment of collagen are examined and related to current anti-scarring therapies using transforming growth factor " The most influential of these …

Univercity News (2000-08-14)

UniverCity News, 1998-2001

VCU Today, the University’s first official administrative organ, began as a somewhat irregular monthly publication but moved to a bi-weekly newspaper format in the 1980s. The newspaper changed its name to VCU Voice in 1988 and ten years later it appeared under the title UniverCity News. As it neared the end of its run as a physical newspaper, the publication became simply VCU News. These four publications were essentially the same periodical published under different titles by the Office of University Relations. VCU News appeared online for the first time in 2002.

Distribution And Ecology Of Freshwater Ostracoda (Crustacea) Collected From Springs Of Nevada, Idaho, And Oregon: A Preliminary Study, Okan Külköylüoğlu, Gary L. Vinyard

Western North American Naturalist

Fourteen freshwater ostracod species collected from 24 springs in Nevada, Idaho, and Oregon between 1991 and 1994 were classified. Their ecology, based on major water parameters (i.e., temperature, dissolved oxygen, pH, conductivity), and biogeographical distribution in North America were studied. Among these 14 species, 9 (Ilyocypris bradyi, I. gibba, Darwinula stevensoni, Candona candida, Heterocypris incongruens, Herpetocypris reptans, H. chevreuxi, Prionocypris canadensis, P. longiforma) are new records for Nevadas ostracod fauna, while 3 (H. reptans, P. canadensis, and Cypria turneri) are new species for Oregon. H. reptans …

Allozyme Variability, Isolation, And Dispersal Of Eusattus Muricatus (Coleoptera: Tenebrionidae) Within Silver State Dune Complex, Great Basin, Western North America, Tammy M. Epps, Hugh B. Britten, Richard W. Rust

Western North American Naturalist

Genetics of Eusattus muricatus (Coleoptera: Tenebrionidae) populations within Silver State Dune Complex in the northern Great Basin of North America were assayed using allozyme electrophoresis. Hierarchical F-statistics showed no significant population subdivision among 3 valleys comprising Silver State Dune Complex. A regression of estimated pairwise gene flow (Nm) against pairwise geographic distance was not significant for populations within these valleys, but it was significant over larger distances. A neighbor-joining phenogram did not represent geographic relationships among populations in the 3 valleys but reflected the past geologic history of these dunes. Pairwise divergence times were low (<7000 yr) for populations within Silver State Dune Complex but were high (>18,000 …

Examining Ecological Consequences Of Feral Horse Grazing Using Exclosures, Erik A. Beever, Peter F. Brussard

Western North American Naturalist

Although feral horses have inhabited western North America since the end of the 16th century, relatively little synecological research has been conducted to quantitatively characterize how they interact with ecosystem components. Because feral horses exhibit watering behavior markedly different from that of domestic cattle, it is particularly important to evaluate response of ecosystem elements near water sources to horse use. To assess this response, we performed live-trapping of small mammals and 2-tiered vegetative sampling in 2 mountain ranges in central Nevada in the interior Great Basin, USA. At low elevations, plots around horse-excluded springs exhibited notably greater plant species richness, …

Diets Of Sympatric Lahontan Cutthroat Trout And Nonnative Brook Trout: Implications For Species Interactions, Jason B. Dunham, Matthew E. Rahn, Robert E. Schroeter, Stewart W. Breck

Western North American Naturalist

Nonnative brook trout (Salvelinus fontinalis) have been implicated in declines of stream-living Lahontan cutthroat trout (Oncorhynchus clarki henshawi), a threatened trout endemic to the Lahontan Basin of northeastern California, southeastern Oregon, and northern Nevada. Brook trout may displace Lahontan cutthroat trout through 2 mechanisms: interspecific predation and competition for food. To evaluate the evidence for these alternatives, we examined stomach contents of 30 trout of each species captured in the North Fork Humboldt River, northeastern Nevada, to compare number, size, and taxonomic composition of prey. Taxonomic dietary overlap was high (81.4%) between brook and Lahontan cutthroat …

Influence Of Substrate Size, Cladophora, And Caddisfly Pupal Cases On Colonization Of Macroinvertebrates In Sagehen Creek, California, Steven D. Ellsworth

Western North American Naturalist

Colonization of stream macroinvertebrates onto artificial substrates was examined in Sagehen Creek, California, during 1993. Substrate size and presence or absence of pupal cases of the caddisfly Anagapetus (Glossosomatidae) were examined as possible influences on macroinvertebrate colonization. Macroinvertebrates were collected from substrates after 60 d of incubation and identified to the lowest feasible taxonomic unit. Dry weight of the filamentous green alga Cladophora also was determined for each substrate.

A general linear model indicated a significant positive relationship between both substrate size and presence of pupal cases on richness (P < 0.001). There was no significant effect of cases on the E5 evenness index, which supports the passive sampling model as a mechanism giving rise to the effect of cases on richness. A multivariate general linear model indicated a significant positive effect of Anagapetus cases on Micrasema bactro, Epeorus, and …

Lahontan Cutthroat Trout (Oncorhynchus Clarki Henshawi) Spawning And Downstream Migration Of Juveniles Into Summit Lake, Nevada, Gary L. Vinyard, Alice Winzeler

Western North American Naturalist

The only remaining self-sustaining native population of lacustrine Lahontan cutthroat trout (Oncorhynchus clarki henshawi) not affected by nonnative salmonids is in Summit Lake, Humboldt County, Nevada. Annual spawning runs in 1993 and 1994 were monitored at a fish trap on Mahogany Creek, the only spawning tributary for Summit Lake. Number of spawners was similar in both years, with 1290 upstream migrants observed in 1993 and 1255 in 1994. In 1993, 137 postspawners (10.6% of upstream migrants) returned to the lake, and in 1994, 434 postspawners (34.6% of upstream migrants) returned downstream through the fish trap. Two distinct groups …

A Comparison Of Riparian Condition And Aquatic Invertebrate Community Indices In Central Nevada, Tom B. Kennedy, Adina M. Merenlender, Gary L. Vinyard

Western North American Naturalist

The importance of maintaining healthy riparian communities to sustain natural stream processes and function is well documented. Land management agencies in the West are currently developing methods to assess and monitor riparian community condition to adapt land use practices that would better protect rangeland ecosystems. To determine whether these methods also provide an indication of abiotic and biotic stream condition, we compared the classification system of riparian communities developed by the U.S. Forest Service (USFS) to physical parameters of stream condition and to aquatic invertebrate community assemblages. Thirty-three sites in 19 different streams of the Toiyabe Range in central Nevada …

Life History Variation In Recently Established Populations Of Western Mosquitofish (Gambusia Affinis), Craig A. Stockwell, Gary L. Vinyard

Western North American Naturalist

We report life history characteristics for 4 recently established populations of western mosquitofish (Gambusia affinis). Mosquitofish from thermally stable habitats, Bonham and Garrett, were characterized by maturity at large sizes, high fat reserves, and large embryos. In contrast, females from a thermally unstable habitat, Wabuska, matured at small sizes and had low fat reserves and small embryos. Females from Parker, a site with no appreciable thermal input, matured at intermediate sizes and had low fat reserves as well as large embryos. These populations shared a common ancestor in 1937; therefore, these results suggest either phenotypic plasticity or rapid …

Effects Of Habitat Fragmentation And Differing Mobility On The Population Structures Of A Great Basin Dragonfly (Sympetrum Corruptum) And Damselfly (Enallagma Carunculatum), Janice L. Simpkin, Hugh B. Britten, Peter F. Brussard

Western North American Naturalist

The population structure of 2 Great Basin odonate species was assessed using protein electrophoresis. Analyses included 7 populations of Sympetrum corruptum (suborder Anisoptera), a migratory and highly mobile dragonfly, and 8 populations of Enallagma carunculatum (suborder Zygoptera), a weak flier that is not known to migrate far from natal water sources. Though we expected the damselfly (E. carunculatum) to show greater genetic isolation than the dragonfly (S. corruptum), both species apparently had high levels of gene flow (theta = 0.0604 for S. corruptum, theta = 0.0485 for E. carunculatum) and showed no evidence for …
