Research object - transport infrastructure of Baku and Baku agglomeration (BA). Research subject - environement-relatedmodes of transportation in Baku andBA, world practices of ecofriendly mobility choices. Research target - form the rationale for tramway and bicycle network development across Baku from ecological point of view. Research methods and methodology - sociological survey, mathematical methods, cartographical and climatic analysis, SWOT analysis, description. Data base - dataof Intelligent Transport Management Center, survey data on popular websites, normative legal base andstatistics reports оf foreign government agencies. Results and approbation - reasults of research could be used for strategy realisation focused on development of sustainable transporation optionsacross ВА. Projected suggestions - initial phase of tramway network (TN) development in Baku intented to construct tramway linealong Baku sea-front. Ongoing project works of railways connecting Baku with Heydar Aliyev International Airport and touristic centers Shakhdag and Gabala will be set in operation in the future.

It is shown that hydrocarbon deposits associated with fossil lacustrine complexes represent a separate genetic group of deposits that differ in terms of a complex of geological, geochemical and geoecological features. The mechanisms of accumulation of sours rocks in lacustrine basins of different hydrological typeare presented. It was established that the lacustrine genesis oil has a better chemical composition compared to liquid hydrocarbons of marine genesis. However, their extraction requires additional economic and environmental costs due to complex geological conditions

In article the attempt is done to estimate the functional role of geochemical barriers (GCB) in relation to properties and evolution of geochemical systems (GCS) becomes. The methodological base is fundamentals of Haken’ synergetics, the idea of self-organization of systems and nonequilibrium (non-linear) thermodynamics of I. Prigozhin and his school. From the author’s positions GCB are considered as the self-organized components of GCS in which an activization of physical and chemical processes is observed. It is leading to transformation of atomic molecular structures, chemical associations and separate chemical elements under the influence of the active medium (processes). They can be the defining phenomenon of emergence and evolution of geochemical systems. From the position of geoecology and geochemistry the estimation of permissible anthropogenic load on natural systems and its rationing are impossible without realizing the GCB role in migration and transformation of pollutants. The concept of geochemical barriers is the basis for actively applied in practice technologies for cleaning and protecting soils, underground and surface waters and the whole geological environment.

The autumn studies of the Phrynocephalus guttatus guttatus Gmel. population in the Astrakhan semideserts (August 2011 and August - September 2016) revealed the following features of its age and sex structure. The autumn settlement of the species reliably splits into several age groups: 1-2 group of young, 2-4 groups of females and 2-5 group of males. In the fall season the settlement is dominated by males, especially great was the numerical superiority of the males in the fall season of 2016.The lack of immature individuals, the significant prevalence of older age groups and the predominance of males among adult animals in the autumn 2016 create the picture of the population depression. The unsustainable type of population dynamics, typical for short-living species, may be one of the characteristics that stimulates the processes of population depression. Almost complete replacement of the population is likely to occur both in two or 3-4 years.

The first results of the implementation of the initiative project realized by the employees of the ecological faculty of the RUDN-University are presented. The project is aimed at obtaining information on the environmental situation and the main sources of impact on the territory of the RUDN-University’ campus. Together with the achievement of this goal, the most important task is solved - the development of practical skills and competences, the formation of a professional ecological culture among environmental students. For the RUDN-University as a national coordinator in the Green Metric Green Universities international movement organized by the University of Indonesia, the project is a landmark and allows the university to demonstrate by its own example to students the opportunities for greening and achieving sustainability, even for non-productive organization.

Осенние полевые исследования популяции круглоголовки-вертихвостки (Phrynocephalus guttatus guttatus Gmel.), проведенные в конце августа 2011 года и в конце августа – начале сентября 2016 года в песчаных полупустынях Астраханской области, выявили следующие особенности ее половозрастной структуры. Осеннее поселение круглоголовок-вертихвосток достоверно распадается на несколько половозрастных групп: 1–2 группы неполовозрелых животных, 2–4 группы самок и 2–5 групп самцов. В осеннем сезоне в поселении преобладали самцы, особенно велик был численный перевес самцов в осенний сезон 2016 года. Отсутствие в осеннем поселении 2016 года неполовозрелых особей, значительный перевес старших возрастных групп и преобладание самцов среди половозрелых животных создали картину общего старения и депрессии популяции. Лабильность типа динамики численности, характерная для коротко живущих видов, может быть одной из характеристик, способствующих процессам популяционной депрессии. Практически полная смена населения исследуемой популяции круглоголовки-вертихвостки, вероятно, может происходить как за два, так и за 3–4 года.
