Disturbance, Response, and Persistence in Self-Organized Forested Communities: Analysis of Robustness and Resilience in Five Communities in Southern Indiana Ecology and Society

We develop an analytic framework for the analysis of robustness in social-ecological systems (SESs) over time. We argue that social robustness is affected by the disturbances that communities face and the way they respond to them. Using Ostrom's ontological framework for SESs, we classify the major factors influencing the disturbances and responses faced by five Indiana intentional communities over a 15-year time frame. Our empirical results indicate that operational and collective-choice rules, leadership and entrepreneurship, monitoring and sanctioning, economic values, number of users, and norms/social capital are key variables that need to be at the core of future theoretical work on robustness of self-organized systems.

Chromosomal localization of selected SCARs converted from new RAPD, ISSR and R-ISSR markers linked to rye (Secale cereale L.) tolerance to nutrient deprivation stress identified using bulk segregant analysis Electron. J. Biotechnol.
Smolik,Milosz.
Background: An adaptive mechanism in plant roots is initiated in the event of nitrogen and potassium deficiency, and it facilitates the active uptake of these elements in order to ensure plant growth and survival in stress conditions. Signaling and transduction of signals in response to changing nitrogen and potassium concentrations is a complex process, affected by interactions between various gene expression products, and often subjected to modifications. Results: In order to identify genotypic differences between phenotypes of two populations of recombinant inbred rye lines (153/79-1 x Ot1-3 and Ot0-6 x Ot1-3) in response to nutrition stress caused by nitrogen and potassium deficiency at the seedling stage, bulk segregant analysis was utilized....

POTENTIAL CORN ACREAGE EXPANSION FOR ETHANOL PRODUCTION: WESTERN NORTH DAKOTA AgEcon
Gustafson, Cole R..
Several recent developments have stimulated farmers' interest in raising corn for ethanol production in northwestern North Dakota. The purpose of this study is to estimate the corn supply response of western North Dakota farmers for ethanol production. Two focus groups of western North Dakota farmers (Williston and Minot) were organized. The market premium over prevailing local corn prices that was required by western North Dakota farms to entice additional production of an ethanol specific hybrid was determined. Aggregation of these farm responses yielded a supply function of corn for the region. Results show that sufficient corn can be produced in the surrounding region to support a 12 million gallon ethanol facility if modest price premiums are...

Animal Disease Pre-Event Preparedness versus Post-Event Response: When is it Economic to Protect? AgEcon
Elbakidze, Levan; McCarl, Bruce A..
We examine the economic tradeoff between the costs of pre-event preparedness and post-event response to the potential introduction of an infectious animal disease. In a simplified case study setting, we examine the conditions for optimality of an enhanced pre-event detection system considering various characteristics of a potential infectious cattle disease outbreak, costs of postevent response actions. We show that the decision to invest in pre-event preparedness activities depends on such factors as probability of disease introduction, disease spread rate, relative costs, ancillary benefits, and effectiveness of mitigation strategies.

The persistence of drought impacts across growing seasons: a dynamic stochastic analysis AgEcon
Peck, Dannele E.; Adams, Richard M..
Agricultural producers throughout much of the United States experienced one of the most severe droughts in the last 100 years during the years 1999-2006. The prolonged nature of this drought highlights a need to better understand the impacts and management of drought across growing seasons, rather than just within a growing season. Producers express specific concern about the tendency of drought impacts to persist even after drought itself has subsided. The persistence of drought impacts has received limited attention in the economics literature. The objectives of this study are two-fold: 1) to determine whether inter-year dynamics, in the form of agronomic constraints and financial flows, can cause persistence of a drought's impact in years subsequent...

Response of nitrogen rates was investigated in Ratchaburi Rice Research Center during dry and wet season 2013 with 10 irrigated promissing rice lines/variety with different nitrogen rates of check 0 6 12 18 24 and 30 kg(N)/rai. The result showed rice yield in dry season 2013 at 6 18 24 and 30 kg(N)rai equal to 505.0 533.6 528.9 and 579.7 kg/rai with nonsignificant but in wet season 2013 there was different yield at 0 6 12 and 18 N-rates with 24 N-rate that gave highly yield of 622.4 kg/rai. In dry season 2013 PTT 00018-10-1-2-1 gave highly yield of 553 kg/rai but non different from RD31 check variety that gave yield of 519.29 kg/rai. The height of rice in dry season 2013 in every rates of N-fertilizer had non significant but PTT00018-10-1-2-1 had lowest...
