ScienceAlerts.com is a natural sciences social network to discover and share scholarly content in in the basic and applied sciences of agriculture, biology, environment, forestry, geography and health. Up to now, 76,018 members have signed up and actively contribute this content. The review process is partly automated and partly manual to ensure that only relevant content will be approved and featured on the site. Since new science content is discovered in real-time, the delay between original publication and appearance at ScienceAlerts.com is usually within minutes.

ScienceAlerts.com’s Agricultural Sciences Category covers the cultivation and production of crops, raising of livestock, and postharvest processing of natural products. It currently contains 36,667 stories partly derived from over 220 scholarly agriculture journals. The latest article covers volatiles to protect brassicaceous crops against the cabbage root fly, Delia radicum. The author’s results confirmed the role of dimethyl disulfide (DMDS) in reducing D. radicum egg numbers on broccoli plants and revealed that (Z)-3-hexenyl acetate, a green leaf volatile released by recently damaged plants, strongly stimulated fly oviposition.

ScienceAlerts.com’s Biological Sciences Category covers life and living organisms, including their structure, function, growth, origin, genetics, and distribution. This category currently contains over 85,008 stories partly derived from over 400 scholarly biology journals. The latest article covers development of sandwich enzyme linked immunosorbant assay for the detection of Cronobacter muytjensii. It demonstrates that the developed method was able to detect all the strains of C. muytjensii and that ELISA technique has potent application for the rapid and accurate detection of C. muytjensii in dietary foods.

ScienceAlerts.com’s Environmental Sciences Category covers the external physical conditions affecting growth, development, and survival of organisms, and their management. It currently contains 157,518 stories partly derived from almost 780 scholarly environment journals. The latest article presents potential contaminant pathways from hydraulically fractured shale to aquifers. The rapid expansion of hydraulic fracturing requires that monitoring systems be employed to track the movement of contaminants and that gas wells have a reasonable offset from faults.

ScienceAlerts.com’s Forestry Sciences Category covers the cultivation, maintenance, and development of forests. This category currently contains over 28,000 stories partly derived from 170 scholarly forestry journals. The latest article attempts to model spatial patterns of fire occurrence in Mediterranean Europe using Multiple Regression and Random Forest. The Random Forest model showed a higher predictive ability than Multiple Linear Regression. Furthermore, the analysis of the residuals also indicated a better performance of the Random Forest model, indicating that this method has potentiality to be applied in the assessment of fire-related phenomena at a broad scale.

ScienceAlerts.com’s Geographical Sciences Category covers the physical characteristics of the earth including its surface features, and the distribution of life on earth. It currently contains over 36,700 stories partly derived from almost 250 scholarly geography journals. The latest article covers ostracod palaeoecology and environmental change in the Laptev and Kara seas (Siberian Arctic) during the last 18,000 years. The study suggests that euryhaline species are largely sea-ice- and/or iceberg-rafted and may therefore provide evidence for a climate cooling trend.

ScienceAlerts.com’s Health Sciences Category covers the effects of disease and medical treatment on the overall condition of organisms. It currently contains over 14,100 stories partly derived from nearly 150 scholarly health journals. The latest article shows that healthier home food preparation methods and youth and caregiver psychosocial factors are associated with lower body mass index (BMI) in African American youth. In this study, adolescent children of caregivers who used healthier cooking methods were more likely to use healthy cooking methods themselves.

Bangkok, Thailand (PRWEB) April 25, 2012

ScienceAlerts.com is a Forestry Sciences Social Network to discover and share scholarly content in in the basic and applied sciences of agriculture, biology, environment, forestry, geography and health. Up to now, 17,821 members have signed up and have actively contributed 1,073,064 articles to the site. The new Forestry Sciences category currently features 27,413 stories largely derived from 26 scientific forestry publishing sources.

This category also provides an Forestry Sciences RSS feed which is one of the best and most popular ways of staying up to date with the latest research in this science discipline. One of the latest articles models spatial patterns of fire occurrence in Mediterranean Europe using multiple regression and random forest. The authors present and compare the results of the application of two different methods to identify the main structural factors that explain the likelihood of fire occurrence at European scale. They applied two different methods for the analysis including traditional multiple linear regression and “Random Forest” which is a non-parametric alternative based on an ensemble of classification and regression trees. The “Random Forest” model showed higher predictive ability than multiple linear regression and could, therefore, be applied in the assessment of fire-related phenomena at a broad scale. Both models indicate that the spatial distribution of fire occurrence likelihood is highly variable in Mediterranean Europe with highest fire likelihood in the northwest region of the Iberian Peninsula and southern Italy, and low fire likelihood in northern France, northeast Italy and north of Greece. Another article associates spatiotemporal variability of tree growth with climate over Northwest China.

Using rotated principal component analysis and hierarchical clustering analysis, the authors found that tree growth was mainly determined by the climate. Most of the tree-ring chronologies in Northwest China showed high correlations with moisture conditions in the current and previous growing seasons. They conclude that climate plays a more important role in determining tree growth in extreme climate conditions relative to non-climate factors.

This category also provides a Forestry Sciences RSS feed which is one of the best and most popular ways of staying up to date with the latest news in this science discipline. One of the latest articles investigates the genetic variation in seedlings of two Turkish Abies species. Seedling mortality was higher in Trojan fir (Abies equi-trojani) compared to Turkish fir (Abies bornmuelleriana) and mortality in both species varied by geographic origin, decreasing from west to east. Terminal and lateral branch bud break were also under strong genetic control. encouraging ongoing tree improvement efforts in North America and Europe to develop planting stock for the Christmas tree industry. Another newly included article presents results of a meta-analysis of consumer’s willingness-to-pay (WTP) premiums for certified wood products. These indicate that frequently purchased wood products and wood products with lower base prices tend to capture higher percentage premiums and that reported WTP estimates have, consequently, increased in recent years. The category also features an article analyzing actors’ power and interests affecting biodiversity in community forestry in Namibia. Following analysis of the biodiversity of 14 community forests in Namibia, the authors of this article conclude that biodiversity in community forestry depends on the interests of powerful actors who use their power to achieve a positive outcome for biodiversity.
