A small isolated population of tesselated snake, Natrix tesselata was found in the Upper Don (Lipetsk Region, Russia). It is the first record of this species in the Central Chernozem Territory of Russia, which is separated from the northern border of the main range by the distance of about 200 km. An isolated population of common frog, Rana temporaria and phenetically peculiar population of fire-bellied toad, Bombina bombina are found here too. Faunistic aspect of new herpetological records is discussed.

Aim. To present the wheat endemics of China as source material for breeding and historical heritage. Results and Discussion. Wheat in China is the second most widely distributed cereal crop after rice. It is cultivated in China from the extreme northern border to the southern one, at altitudes from 154 m below sea level to 4450 m above sea level. The Chinian wheat is originated from South-West and West Asia and has a history of more than 2.8 thousand years. Since ancient times, the wheat species have been grown in China: bread (Triticum aestivum L.), compactum (T. compactum Host), polonicum (T. polonicum L.), turgidum (T. turgidum L.), durum (T. durum Desf.), turanian (T. turanicum Jakubz.). The Chinese ancient bread wheats are of interest for breeders because presence among them of early ripening, multi-flowering with the grain number in a spikelet up to 7-8 and in the ear up to 90-100, drought and winter hardy, resistant to powdery mildew and leaf rust; forms with good crossability with rye and Aegilops species. Among the endemic Chinese wheat, an important place belongs to the Chinese Spring variety which played an outstanding role in wheat genetics; super dwarfs Tom Pouce and Tibetan Dwarf; three-grain wheat, in which 3 grains are formed in one flower; Charklyk ancient wheat – a boneless form of polonicum wheat; dwarf blue wheat turgidum – with a strong waxy coating; Taigu-Male-Sterile Wheat – with gene male sterility; a wheats having species and subspecies status: wheat of Petropavlovskyi – Triticum petropavlovskyi Udacz. et Migusch.; Tibetan wheat – T. spelta L. ssp. tibetanum (Shao) N.P. Gontsch comb. nov .; Yunnan wheat – T. spelta L. ssp. yunnanse (King ex S.L. Chen) N.P. Gontsch comb. nov. The origin and genetic characteristics of China's endemic wheats are discussed. Conclusions. China's wheat endemics need careful study and conservation as a reserve of valuable genes and their complexes for breeding, and as an embodiment of the history, culture, talent and work of the people who created them, and an integral part of human cultural heritage.

Removal Of Metal Ions

: Manuscript discussed about the role of polysaccharides and their derivatives in the removal of metal ions from industrial waste water. Quick modernization and industrialization increases the amount of various heavy metal ions in the environment. They can possess various disease in humans and also causes drastic environmental hazards. In this review the recent advancement for the adsorption of heavy metal ions from waste water by using different methods has been studied. Various natural polymers and their derivatives are act as effective adsorbents for the removal of heavy metal ions from the waste water released from the industries and the treated water released into the environment can decreases the chances of diseases in humans and environmental hazards. From the literature surveys it was concluded that the removal of heavy metal ions from the industrial waste water was important to decrease the environmental pollution and also diseases caused by the heavy metal ions. Graft copolymers were acts as most efficient adsorbent for the removal of heavy metal ions and most of these followed the pseudo first order and pseudo second order model of kinetics.

New Research

In Latin America, based on the recognition of Indigenous Peoples, the identification of gaps or disparities between the Indigenous and non-Indigenous population has emerged as a new research interest. To this end, capturing Indigenous identity is key to conducting certain analyses. However, the social contexts where the identity of Indigenous persons are (re)produced has been significantly altered. These changes are generated by the assimilation or integration of Indigenous communities into dominant national cultures. Within this context, limitations emerge in the use of this category, since Indigenous identity has a political and legal component related to the needs of the government. Therefore, critical thought on the use of Indigenous identity is necessary in an epistemological and methodological approach to research. This article argues that research about Indigenous Peoples should evaluate how Indigenous identity is included, for it is socially co-produced through the interaction of the State and its institutions. Thus, it would not necessarily constitute an explicative variable. By analyzing the discourse about Aymara Indigenous communities that has emerged in the northern border of Chile, this paper seeks to expose the logic used to define identity. Therefore, I conclude that the process of self-identification arises in supposed Indigenous people, built and/or reinforced by institutions, which should be reviewed from a decolonizing perspective and included in comparative research.
