Mexico City houses one of the most populous urban areas of the world, and the modification of its natural habitat likely influences the biological diversity found there. In particular, amphibians and reptiles are likely affected by these modifications. Herein, we present an updated list of the species of amphibians and reptiles that inhabit Mexico City. Mexico City harbors 65 species of amphibians and reptiles, which represent 21 families and 33 genera. These include 18 species of amphibians (nine anurans and nine salamanders) and 47 species of reptiles (14 lizards, 30 snakes [one introduced], and three turtles [one introduced]). Forty-eight of the amphibian and reptile species in Mexico City are endemic to Mexico, with two endemic to Mexico City. The most diverse region of Mexico City is the Forests and Ravines region, which is home to 43 species. Eleven species of amphibians and reptiles in Mexico City are IUCN listed, 16 are placed in a protected category by SEMARNAT (Secretaria del Medio Ambiente y Recursos Naturales), and 27 species are categorized as high risk by the EVS (Environmental Viability Score). Mexico City shares almost 94% of its species with the State of Mexico.

The State of Mexico has a unique combination of geographic characteristics and topography that promotes a high biodiversity. Unfortunately, continued human population growth of the metropolitan areas of Mexico City and Toluca have degraded the environment of the State of Mexico, which threatened its wildlife. An updated checklist of the amphibians and reptiles of the State of Mexico is provided and their conservation status summarized. The State of Mexico has 49 species of amphibians and 101 species of reptiles. The majority of the amphibians (73.5%) and reptiles (70.3%) found in the State of Mexico are endemic to Mexico. Of the amphibian and reptile species in the State of Mexico, 20.1% are IUCN listed (i.e., Vulnerable, Near Threatened, or Endangered), 18.4% are placed in a protected category by SEMARNAT (excluding NL and Pr, this last category is equivalent to the LC category of IUCN), and 34.9% are categorized as high risk by the EVS. The importance of forested habitats for the protected amphibians and reptiles in the State of Mexico suggest that management of these habitats to maintain or expand them needs to be considered.

WHO declared Corona Virus disease 2019 (COVID-19) as a public health emergency on the 30th of January 2020. Soon afterward, COVID-19 cases started to emerge from all parts of the world. The state of Qatar was extremely vigilant from the very outset. Special measures were introduced immediately to restrict the influx of people from high-risk countries such as China and Iran. The Ministry of public health (MOPH), Qatar started preparing for an impending pandemic in the meantime. The first cluster of COVID-19 positive cases was declared on March the 11th 2019. A total of 238 cases were declared positive on this day. It raised the alarm to roll over all those preparations on the ground into practice

Авторы рассказывают об участии в индийской антропологической экспедиции (сезон 2019 г.), учрежденной Центром палеоэтнологических исследований совместно с Государственным биологическим музеем (Москва). Цель индийского проекта — изучение народов Южной Азии как макрорегиона, обладающего огромным этнокультурным и биологическим разнообразием. В области материальной культуры Индия сохраняет множество уникальных реликтов в области технологий, морфологии предметов и их функций, что в большинстве регионов мира уже утрачено. В области физической антропологии Индия фактически неисчерпаема. Первый полевой сезон состоялся в июне 2018 г., а в 2019 г. авторы занимались комплексным антропологическим изучением трипури и бенгальцев. The authors tell about their participation in the Indian anthropological expedition (season 2019), established by the Center for paleoethnological research in cooperation with the State Biological Museum (Moscow). The purpose of the Indian project is to study the nations of South Asia as a macro-region with a huge ethno-cultural and biological diversity. In the field of material culture, India preserves many unique relics in the field of technology, morphology of objects and their functions, which have already been lost in most regions of the world. In the field of physical anthropology, India is virtually inexhaustible. The first field season took place in June 2018, and in 2019, the authors were engaged in a comprehensive anthropological study of Tripuri and Bengalis.

Biological diversity is the vital organic resource on which the present and future sustenance of humankind depends. The farm animal genetic resource (AnGR) sector of this diversity provides the variety and variability of species, breeds and populations including unique genotypes which underpin an essential component of food and agriculture production. Judicious use and enhancement of these living resources must be ensured, also with their conservation, so that we may meet the increasing demands for food.

The volume of derivatives in American banks grows significantly, high risk instruments are back in place and their use becomes more active, global imbalances increase. All of the above requires thorough approaches when creating mechanisms which can neutralize external shocks for the Russian economy and make it possible to develop in the new post-crisis environment.

The paper examines various approaches to the definition of the term «digital economy» in the scientific and business environment along with factors and forms of its development in different countries taking into account the specifics of the current stage of the Russian economy, which is a matter of particular importance in seeking new sources of the world economy growth. The subject of the research is opportunities and threats inherent in the process of digitalization of economies and their impact on the operation of international and national markets as well as the development of the world economy as a whole. The purpose of the paper was to analyze the practical experience in the formation and development of the digital economy in foreign countries and Russia and identify the changes it brings to the activities of state institutions and business structures, established rules of market exchange, the process of promotion and use of innovations. All the above made it possible to determine the country-level specifics of the digital economy evolution reveal the contradictory nature of its manifestations and justify the necessity for active participation of the state in stimulation and support of potentially promising digital innovations in various sectors of the economy. It is concluded that the level of the digital economy development depends on the real-sector performance, the maturity of markets, the state of the national economy. It is highlighted that the criteria for a comprehensive assessment of the results of the economy digitalization must be developed.
