BACKGROUND AND AIMS Ongoing and previous range expansions have a strong influence on population genetic structure of plants. In turn, genetic variation in the new range may affect the population dynamics and the expansion process. The annual Ceratocapnos claviculata (Papaveraceae) has expanded its Atlantic European range in recent decades towards the north and east. Patterns of genetic diversit...

At least four different modeling studies indicate that variability in snow cover over Asia may modulate atmospheric circulation over the North Pacific Ocean during winter. Here, satellite data on snow extent for east Asia for 1971–95 along with atmospheric fields from the National Centers for Environmental Prediction–National Center for Atmospheric Research reanalysis are used to examine whethe...

There are large discrepancies among estimates of the cropland area in China due to the lack of reliable data. In this study, we used Landsat TM/ ETM data at a spatial resolution of 30 m to reconstruct spatial and temporal patterns of cropland across China for the time period of 1990–2000. Our estimate has indicated that total cropland area in China in 2000 was 141.1 million hectares (ha), inclu...

The Mediterranean Intensive Oxidant Study, performed in the summer of 2001, uncovered air pollution layers from the surface to an altitude of 15 kilometers. In the boundary layer, air pollution standards are exceeded throughout the region, caused by West and East European pollution from the north. Aerosol particles also reduce solar radiation penetration to the surface, which can suppress preci...

We predict the sectoral trade and real wage impact of free skilled migration in the enlarged EU, whose members we group as North (wealthiest EU), South (Greece, Portugal and Spain) and East (acceding Central and Eastern European countries). The North consolidates its current hub position by attracting more firms and skilled workers. Thus its net exports of high scale economy, skill-intensive go...

Consider an r × (n − r) plane lattice rectangle, and walks that begin at the origin (south-west corner), proceed with unit steps in either of the directions east or north, and terminate at the north-east corner of the rectangle. For each integer k we ask for N k , the number of ordered pairs of these walks that intersect in exactly k points. The number of points in the intersection of two such ...

In this paper, we address the question of whether official development assistance promotes gender equality in the Middle East and North Africa region by examining the effects of aid to Women’s Equality Organizations and Institutions on women’s political empowerment, measured by the proportion of seats held by women in national parliaments. We use panel data (covering the period 2002-10) from 13...

The record of Anelytra (Anelytra) eunigrifrons Ingrisch, 1998 (Conocephlinae: Agraeciini) collected from Umiam in the North-east province, Meghalaya (India) is reported for the first time. Previously, the species was reported from Indo-China, Myanmar Burma, and Shan province, Carin Ghecu (Ingrisch, February 01, 1888 to March 31, 1888 and 1998). From India only one species, Anelytra (Anelytra) c...
