The global homogenization of the Earth’s biota is expected to increase due to the increase in movement of people and goods between regions, and many introduced species are having a negative economic impact. The increase of introduced species can be thought of as a major global change, because ecosystems throughout the world are now impacted by exotics [1, 2]. Grasslands, which cover roughly 25%...

Salinity, which is more common in semi-arid and arid areas, increasing every day with climate change, poor quality irrigation water, soil structure. High salt concentration restricts plant production causes productivity loss agriculture. To sustain agriculture saline soils, the determination of species resistant to salinity comes into prominence areas problems. For this reason, research was per...

Germination cues reflect the conditions under which a species is likely to succeed in recruitment. Therefore, knowledge of the seed germination characteristics of key plant species in desertified areas is essential for restoration. The aims of this study were to evaluate the seed germination responses of seven native species, and to explore the implications for vegetation restoration. Seeds of ...

The seasonal change and host preference of arbuscular mycorrhizal (AM) colonization and community composition of five common plant species Agropyron cristatum, Anemarrhena asphodeloides, Cleistogenes squarrosa, Leymus chinensis, and Stipa grandis in the Inner Mongolia steppe were investigated. The AM root length colonization rates were different among the five plant species and were generally h...

The biotypic diversity of the Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), was assessed in five isolates collected in Colorado. Three isolates, RWA 1, RWA 2, and an isolate from Montezuma County, CO, designated RWA 6, were originally collected from cultivated wheat, Triticum aestivum L., and obtained from established colonies at Colorado State University. The fourth ...

A Barcé-halom Dévaványa külterületén, a településtől nyugatra található. 1970-ben régészeti feltárás igazolta kurgán késő rézkori–kora bronzkori eredetét, dokumentált temetkezés Jamnaja-kultúrához köthető. római korban környékét szarmaták lakták. halomfelszínt 18. század vége óta szántóföldként hasznosították. Az 1930-as években keleti oldalából nagymennyiségű földet hordtak el, roncsolás nyoma...
