This contribution presents the study of species-group of Plumarius Philippi 1873, as the result of a survey of the morphological variation in males. The group is characterized by the large ocelli and transverse head. It consists of the following three new species: P. culminatus Diez, Fidalgo & Roig-Alsina, sp. nov., P. ocellatus Diez, Fidalgo & Roig-Alsina, sp. nov., and P. stangei Diez, Fidalg...

Prediction of agricultural yields is a challenging task that demands fusion of knowledge from different areas such as data mining, statistics and agriculture. This paper shows that data mining techniques can be successfully applied to agricultural data analysis. Results that we present are gained on the data set that contains monthly measurements of different environmental parameters and annual...

Study of the effect of pesticides on soil micro flora and their beneficial activities forms an important part of the pesticides risk assessment . The intensive use of these pesticides in agricultural soils, there may be an interaction with soil micro flora and their metabolic activities besides, controlling the different pest population (Baxter and Cummings, 2008). Therefore the behavior of the...

abstract the objective of this study is to investigate the long run and short run interactions between agricultural trade liberalization and shares of the two sectors of agriculture and services in the total export and import products and services of iran during the years 1961-2008. to figure out interactions, the vector correction model was used. the ratio of the sum of imports and exports to ...

We examine the interannual variability in the NO2 column over North America measured by the Ozone Monitoring Instrument (OMI) in 2005–2008. By comparison to a model of soil NOx emissions driven by the North American Regional Reanalysis precipitation and 0–10 cm soil temperature fields, we show the source of this observed interannual variability over much of the central United States in June is ...

We estimate a model of common and commodity-specific, highand low-frequency factors, built on the spline-GARCH model of Engle and Rangel (2008) to explain the period of exceptionally high price volatility in commodity markets during 2006-2008. We find that decomposing realized volatility into highand low-frequency components reveals the impact of slowly-evolving macroeconomic variables on the p...

With South–South economic cooperation on the rise, there are many opportunities for developing countries to benefit from the experiences of their more successful counterparts in the developing world through enhanced trade and investment links and knowledge transfer. Since 2005, rising international demand for food products, the diversion of some food crops to biofuel production, and excessive s...
