Abstract:

Although Eurasia’s Caspian basin once supported the world’s richest and most diverse complex of sturgeon species, recent human activities have decimated populations of these ecologically and economically important fish. All five anadromous Caspian sturgeon species are critically endangered, and the potamodromous sterlet is also threatened. The precipitous decline of these species is due to a combination of factors that includes illegal, unreported, and unregulated (IUU) fishing; destruction of feeding and spawning habitat; water pollution; and the environmental consequences of climate change.

Abstract:

The article focuses on the environmental legislation of the Islamic Republic of Iran, which regulates, among other things, the issues of protecting the environment of the Caspian Sea. Iran, like other Caspian states, is aware of the need to protect and protect the Caspian marine environment, on which the state of the coastal provinces and the well-being of the local population depend. There are examined the main legal acts of Iran related to the management of the quality of water resources, the protection of the marine environment from pollution, the protection of biological resources.

A check-list of the Caspian Sea fishes (taxa from families down to subspecies) is provided. Eighty species and subspecies permanently occur or occasionally recorded from the North Caspian while 33–35 species and subspecies being only distributed in the Middle and South Caspian. Forty-four species are common for the two ecoregions. A comparison of the Caspian and the Black Sea fish faunas and their historical evolution

The article explores the peculiarities of international legal regulation of the special legal status of the Caspian Sea, legal regimes created by the Convention on the Legal Status of the Caspian Sea the adoption of which in 2018 marked the establishment of a system of treaties with regard to the Caspian Sea. The Convention aims to avoid fragmentation of international legal regulation and represents the result of the codification of the most important issues of regional cooperation among the Caspian States. It is noted that the water area of the Caspian Sea is divided into internal waters, ter

Abstract:

For many years, the primary environmental problem of the Caspian Sea has been oil pollution, which is associated both with oil production and transportation, as well as changes in sea level, leading to secondary pollution, river runoff and even seismic activity, which provokes natural oil spills from the bottom of the sea. Abnormal bloom of waters every year becomes more and more long and covers more and more areas, and also occurs in areas where it was not previously observed. However, the current state of the sea, and the trends of its evolution has not been studied enough, which determines

Dynamic changes to the northern Caspian Sea shoreline have significant ecological implications, including impacts to biodiversity and the surrounding environment. This study employs Landsat datasets, historical records, and geographic information systems (GIS) to quantitatively analyze spatiotemporal variations along the northern Caspian Sea coastline from 1985 to 2023. The findings demonstrate pronounced cyclic variations in the Caspian Sea’s water level. Compared to 1930, the water level decreased by 2.6 m by 2023, with 1935 marking the onset of a significant downward trend. From 1995 to 202

Abstract:

ABSTRACT Human interventions on the Earth’s natural systems are evident even in remote regions of the Antarctic and rain forests deep within the Amazon. In addition to human-induced climate change and habitat destruction, an emerging anthropogenic threat to biodiversity is the drastic species re-distribution (the movement of species from one place to another due to human intervention) at a global scale. This creates fertile conditions for biological invasions which in turn cause substantial economic and ecological losses. These human-mediated invasions, often referred to as “biological polluti
