Modeling Methane Emission From Wetlands In North-Eastern New South Wales, Australia Using Landsat Etm+, Clement E. Akumu, Sumith Pathirana, Serwan Baban, Daniel Bucher

Agricultural and Environmental Sciences Faculty Research

Natural wetlands constitute a major source of methane emission to the atmosphere, accounting for approximately 32 ± 9.4% of the total methane emission. Estimation of methane emission from wetlands at both local and national scale using process-based models would improve our understanding of their contribution to global methane emission. The aim of the study is to estimate the amount of methane emission from the coastal wetlands in north-eastern New South Wales (NSW), Australia, using Landsat ETM+ and to estimate emission with a temperature increase. Supervised wetland classification was performed using the Maximum Likelihood Standard algorithm. The temperature dependent factor was …

The Economic Importance Of Draught Oxen On Small Farms In Namibia's Eastern Caprivi Region, Andrew B. Conroy, Mogos Yakob Teweldmehidin

Natural Resources & the Environment

The main aim of this study was to analyse and document the value of smallholder farmers’ use of Draught Animal Power (DAP) systems in the Eastern Caprivi Region and to test the economic viability of DAP usage versus using tractors. This study applied Rapid Rural Appraisal techniques (RRA), including a survey. Semi-structured interviews were conducted with 312 farmers at their farms and data was gathered on the use of and economics related to the draught animal power system. Crop enterprise budgets, project reports, expert opinions and group discussions were analysed. The research found that the use of animal power performs …

Urban Farm: Naturally Grown Local Food, Stephanie Shepard

Interior Design Program: Terminal Projects

There are many things to be said for the benefits of urban farming. From feeding the hungry, to providing an educational experience for a community that otherwise has no agricultural knowledge, to reducing heat island effect, the gain is almost immeasurable.

According to the United States Census Bureau, 35.9 million people live below the poverty line in America. Requests for emergency food assistance has increased by an average of 14% a year since 2004 and about 20% of those requests generally go unmet. In addition, national food banks report that 23.3 million people turned to their services in 2009, an …

A Discounted Cash Flow Method Of Valuation For Single Trees And Urban Forests, Kristin Heffelfinger

All Theses

Urban foresters need a consistent method for valuing single trees with specific non-timber values. There are several accepted methods to accomplish this; comparison of results across the methods ensures consistency. Discounted cash flow analysis (DCF) is one of these methods, but many appraisers or others valuing urban tree are reluctant to use it because it requires complex calculations and assumptions. However, DCF has the advantage of accounting for the time value of money and certain intangible benefits presented by urban trees. Current models are adapted to specific locations and species; a general method for urban tree valuation has not been …

Handling Baby Poultry, David D. Frame, Kerry A. Rood

All Current Publications

With an increase in backyard poultry raising, and even keeping poultry as pets, it is necessary to keep in mind proper health concerns in handling baby poultry. Chickens, ducks, geese, turkeys, peafowl, and game birds can harbor and transmit certain agents that might infect people. This fact sheet will review practices that will help minimize the chance for disease transmission between you and your poultry.

Grapevine And Soil Water Relations With Nodding Needlegrass (Nassella Cernua), A California Native Grass, As A Cover Crop, Michael J. Costello

Wine and Viticulture

Nodding needlegrass [Nassella cernua (Stebbins & R.M. Love) Barkworth], a California native perennial grass, was tested for its effects on grapevine and soil–water relations in a drip-irrigated vineyard in Parlier, CA. Vine water status and in-row and between-row soil moisture (at 0.3 m, 0.6 m, 0.9 m, 1.2 m, and 1.5 m) were monitored semiweekly from June to September. There was no overall significant difference in leaf water potential between treatments. In-row soil moisture was lowest at depths of 0.6 m to 0.9 m within the nodding needlegrass treatment but was lowest from 0.3 m to 0.9 m within the …

Garlic As An Alternative Anthelmintic In Sheep, A. Curry, B. D. Whitaker

Virginia Journal of Science

An increase in the anthelmintic resistance of parasites in small ruminants and a push towards non-chemical farming has led researchers to search for alternative forms of anthelmintics. The efficacy of treating sheep by using natural garlic extract with respect to changes in weight, fecal egg counts (FEC), and packed cell volume (PCV) was investigated. Sheep were treated every 4 weeks for 8 weeks with saline (control) Ivermectin, or natural garlic extract and samples were collected weekly to determine FEC and PCV. Sheep were weighed at the time of sample collection to determine weight change. There were no significant differences between …

Molecular Evidence For A Functional Ecdysone Signaling System In Brugia Malayi, George Tzertzinis, Ana L. Egaña, Subba Reddy Palli, Marc Robinson-Rechavi, Chris R. Gissendanner, Canhui Liu, Thomas R. Unnasch, Claude V. Maina

Entomology Faculty Publications

BACKGROUND: Filarial nematodes, including Brugia malayi, the causative agent of lymphatic filariasis, undergo molting in both arthropod and mammalian hosts to complete their life cycles. An understanding of how these parasites cross developmental checkpoints may reveal potential targets for intervention. Pharmacological evidence suggests that ecdysteroids play a role in parasitic nematode molting and fertility although their specific function remains unknown. In insects, ecdysone triggers molting through the activation of the ecdysone receptor: a heterodimer of EcR (ecdysone receptor) and USP (Ultraspiracle).

METHODS AND FINDINGS: We report the cloning and characterization of a B. malayi EcR homologue (Bma-EcR). Bma-EcR dimerizes with …

Sucrose, Water And Nutrient Use During State Ii Multiplication Of Two Turmeric Clones (Curcuma Longa L.) In Liquid Medium, Jeffrey Adelberg

Publications

Two clones of turmeric (Cucruma longa L.) were assessed nine times during a 28-day culture period in double phosphate MS liquid medium containing 2%, 4% and 6% sucrose. The phase of rapid shoot bud multiplication lasted for 21 days or less, in both clones in all media. The maximum multiplication rate was 3.4× at 20 and 19 days, with 3.9% or 4.7% initial sucrose concentration being optimal for the clones 9-3 and 35-1, respectively. Dry mass increased over the entire culture period and was greatest with 4.8% or at least 6% initial sucrose concentration for the two clones, 9-3 …

What Contributions Are Invasive Plant Species Making To Ecosystem Services?, Stephen L. Young

West Central Research and Extension Center, North Platte

Invasive plant species can establish in diverse environments, and, with the increase in human mobility, they are no longer restricted to isolated pockets in remote parts of the world. Cheatgrass (Bromus tectorum L.) in rangelands, purple loosestrife (Lythrum salicaria L.) in wetlands, and tamarisk (Tamarix spp.) in riparian areas are examples of invasive plant species that are common to the United States and can be found in monocultures and patches covering many thousands of hectares. Across the world, invasive plant species like water hyacinth (Eichhornia crassipes), cogon grass (Imperata cylindrica), and mile-a-minute weed …

Carbon Capture Project, Final Report. An Evaluation Of The Opportunity And Risks Of Carbon Offset Based Enterprises In The Kimberley-Pilbara Region Of Western Australia, Mark Alchin, Elizabeth Tierney, Chris Chilcott

Bulletins 4000 -

Commercialisation of carbon in the Australian Rangelands could lead to the development of a multi-billion dollar industry, and Western Australia has the potential to capture a significant share of this revenue. A significant proportion of the WA Rangelands is degraded which is the legacy of the exploitative practices of historical pastoral development and the mining industry. Full environmental restoration of these areas is well beyond the fiscal capacity of land managers and the WA State Government. Carbon based enterprises have the potential to restore large tracts of degraded land in a cost-effective manner and can deliver a number of other …
