Correlation Of Trichome Density And Length And Polyphenol Fluorescence With Susceptibility Of Five Cucurbits To Didymella Bryoniae, Gabriel Rennberger, A. P. Keinath, M. Hess

Publications

The fungal pathogen Didymella bryoniae causes gummy stem blight and black rot on a broad spectrum of cucurbits. However the substantial differences in susceptibility among Cucurbitaceae are not well studied. Susceptibility was characterized with muskmelon (Cucumis melo), watermelon (Citrullus lanatus), cucumber (Cucumis sativus), pumpkin (Cucurbita pepo), and zucchini (C. pepo). Lesion diameters on leaf disks inoculated with agar plugs were measured 7 days after inoculation, and the necrotized areas of leaf disks inoculated with conidial suspensions were measured 48 h after inoculation (hai). For each species, the number of trichomes …

A Revision Of Prespelea Park (Staphylinidae, Pselaphinae), Michael S. Caterino, Laura M. Vásquez-Vélez

Publications

We revise the genus Prespelea Park, redefining and redescribing the two previously known species, P.copelandi Park and P. quirsfeldi Park, and adding ten new species: P. parki Caterino & Vásquez-Vélez, sp. n., P.minima Caterino & Vásquez-Vélez, sp. n., P. morsei Caterino & Vásquez-Vélez, sp. n., P. divergens Caterino & Vásquez-Vélez, sp. n., P. carltoni Caterino & Vásquez-Vélez, sp. n., P. myersae Caterino & Vásquez-Vélez, sp. n., P. georgiensis Caterino & Vásquez-Vélez, sp. n., P. enigma Caterino & Vásquez-Vélez, sp. n., P. wagneriCaterino & Vásquez-Vélez, sp. n., and P. basalis Caterino …

Exchange Of Polar Lipids From Adults To Neonates In Daphnia Magna: Perturbations In Sphingomyelin Allocation By Dietary Lipids And Environmental Toxicants, Namrata Sengupta, Delaney C. Reardon, Patrick D. Gerard, William S. Baldwin

Publications

Because xenosensing nuclear receptors are also lipid sensors that regulate lipid allocation, we hypothesized that toxicant-induced modulation of HR96 activity would alter lipid profiles and the balance between adult survival and neonate production following exposure in Daphnia magna. Adult daphnids were exposed to unsaturated fatty acid- and toxicant- activators or inhibitors of HR96 and later starved to test whether chemical exposure altered allocation toward survival or reproduction. The HR96 activators, linoleic acid and atrazine, decreased reproduction as expected with concomitant changes in the expression of HR96 regulated genes such as magro. The HR96 inhibitors, docosahexaenoic acid (DHA) and triclosan, …

Repository Review: Nasa Pubspace, Laura Pope Robbins

Publications

Laura Pope Robbins is an advisor for The Charleston Advisor, and the review below is included in Scholarly Commons with the permission of the publisher.

PubSpace is a repository of full-text peer-reviewed articles resulting from NASA-funded research going back to 1961. The National Center for Biotechnology Information has integrated PubSpace into PubMed Central, a freely available repository of medical research. Using an established, stable, government-hosted platform for PubSpace seems to make sense. However, the lack of clear branding, an uneven application of phrase searching, and a missing thesaurus of NASA terminology highlights that this integration may not be the best.

Information Technology Approaches To Forest Management, Mary Snow, Richard Snow

Publications

The majority of the world’s forests occur where there is a dry season long enough to affect a seasonal change in the forest community. The seasonal forest may include evergreen, semi-deciduous, deciduous trees, or some combination of these. Local differences in soil or other site characteristics often determine which community persists. Since the seasonal forests exist where there is seasonal precipitation, the character of the forest is closely associated with the length of the rainy season. As the length of the rainy season decreases, the density of the canopy decreases. If the global climate system warms and prolonged drought gives …

Assessing The Efficiency Of Different Sustainable Farming Practices In Reducing The Environmental Impacts Caused By Aquaculture, Rajee Olaganathan, Alicia Tang Kar Mun

Publications

Sustainability of aquaculture is achieved when aquaculture farming systems are capable of preserving the natural resource base and involves an institutional change to the environment by the attainment and continued satisfaction for present and future generations. Sustainable farming practices produce sufficient aquaculture output to satisfy the seafood demand while not burdening the environment more. The potentiality and efficiency of different sustainable aqua farming practices in reducing anthropogenic impacts to the environment by aquaculture are assessed in this paper. Polyculture is mostly adopted by small-scale rural farmers as it requires low entry barrier and help in income diversification. The input of …

Technological Modernization And Its Impact On Agriculture, Fisheries And Fossil Fuel Utilization In The Asia Pacific Countries With Emphasis On Sustainability Perspective, Rajee Olaganathan, Kathleen Quigley

Publications

Modernization is a process that moves towards efficiency. This affects most of the fields such as agriculture, fisheries, forestry, urban planning, policy, fossil fuel usage, manufacturing, technology, economic growth etc. This process plays a major role in moving forward making things faster, better and basically more efficient. The effects of modernization on all these fields bring about the major changes to aspects such as social, economic and the environment. The level of operation has increased from a domestic level; small family scale business to large commercial levels. As the level of operation increased, the utilization of natural resources increased gradually …
