A comprehensive assessment of the impacts of climate change on agro-ecosystems over this century is developed, up to 2080 and at a global level, albeit with significant regional detail. To this end an integrated ecological-economic modelling framework is employed, encompassing climate scenarios, agro-ecological zoning information, socio-economic drivers, as well as world food trade dynamics. Sp...

Range shifts have been documented in many organisms, and climate change has been implicated as a contributing driver of latitudinal and altitudinal range modifications. However, little is known about what species trait(s) allow for faster environmental tracking and improved capacity for distribution expansions. We used data for 416 species of moths, and show that range limits in Sweden have shi...

Antibiotic resistance has been considered a major human health threat that may endanger the success of medicine. Recent studies have unveiled worldwide asymmetries antibiotic occurrence, being factors as diverse climate, socioeconomic, or use possible drivers such asymmetric distribution. In Europe, where clinical is surveyed for more than 20 years, European Center Disease Prevention and Contro...

A random climate field over the globe can be decomposed into a series of spherical harmonic functions. This paper shows that the mean square sampling error for a spherical harmonic coefficient is composed of aliased powers from other spherical harmonic omponents due to the spatial gaps in sampling networks. A general formula is given for calculating the aliased powers. On the basis of the spect...

Food security and economic welfare strongly depend on agricultural production, the loss of this production can be a serious challenge for food security and economic welfare. Agricultural production is also influenced by environmental and climatic factors so that the variations of climatic parameters can trigger extensive fluctuations in agricultural production. This study classifies climate cha...

: In order to study the effect of different nitrogen levels on yield components and seed yield of three barley cultivars, an experiment was conducted in 2011-2012 in a research farm of farming building of Islamic Azad University Khorasgan (Isfahan) Branch located in Khatunabad village (latitude 32o /40' N and Longitude 51o /48' E). A split plot layout within randomized com...

China, a country that occupies a vast territory with a diverse climate, varied topography and great variety of flora and fauna, is situated in the southeastern Asia. Its land extends from longitude 73 0 E to 135 0 E, a stretch of over 3,200 miles. From north to south, it spans from latitude 53 0 N to 4 0 N, covering a distance of 3,400 miles. The varied climate crosses frigid, temperate, subtro...

Our planet shows striking gradients in the species richness of plants and animals, from high biodiversity in the tropics to low biodiversity in polar and high-mountain regions. Recently, similar patterns have been described for some groups of microorganisms, but the large-scale biogeographical distribution of freshwater phytoplankton diversity is still largely unknown. We examined the species d...
