Artemisia species, which are medically beneficial, are widespread in temperate regions of both Northern and Southern hemispheres among which Iran is located. About 35 species of Artemisia are indigenous in Iran among them some are widespread in all or most provinces, yet some are restricted to some specific regions. In this review paper, initially, GC-Mass results of some experiments done in di...
We present some Language Technology applications and resources that have proven to be valuable tools to promote the use of Basque, a low density language. We also present the strategy we have followed for almost twenty years to develop those tools and derived applications as the top of an integrated environment of language resources, language tools and other applications. In our opinion, if Bas...
1. Japan is an island with approximately 70% of land covered by mountain forests and where arable space is limited. Fishing communities are located in all coastal areas nationwide. Food resources from the ocean have historically played a significant role in the Japanese diet. Even today, around 40% of protein consumed by Japanese people comes from sea food. 2 Ensuring the long-term sustainabili...
Unintentional and illegal introductions of species disrupt food webs and threaten the success of managed sport fisheries. Although many populations of Burbot Lota lota are declining in the species’ native range, a nonnative population recently expanded into Flaming Gorge Reservoir (FGR), Wyoming–Utah, and threatens to disrupt predator–prey interactions within this popular sport fishery. To dete...

The reported annual yield from inland capture fisheries in 2008 was over 10 million tonnes, although real catches are probably considerably higher than this. Inland fisheries are extremely complex, and in many cases poorly understood. The numerous water bodies and small rivers are inhabited by a wide range of species and several types of fisher community with diversified livelihood strategies f...
Small-scale fisheries have historically been marginalized in management and policy investments, and they often remain under-reported in national economic and fisheries statistics. Even so, small-scale fisheries are not entirely buffered from the impacts of globalization, such as the introduction and expansion of markets. This study measures the long-term impact of market-access on a coastal fis...
