Changes in avifauna under the influence of technogenic objects in the coastal zone of the Murmansk region

The article analyzes in detail the impact of man-made objects on the avifauna in the coastal zone of the Murmansk region. Based on the route records of 2022, the study reveals the dynamics of changes in bird populations and their diversity in the context of various biotopes exposed to man-made impacts. The results of the study identify problem areas and provide a basis for biodiversity conservation strategies in the region.

Introduction. In the light of the active anthropogenic impact on natural ecosystems, the issue of studying changes in avifauna is becoming more and more relevant. The article you are holding in front of you is a detailed study of this problem in the context of the coastal zone of the Murmansk region. The Murmansk region, with its diversity and richness of bird species, as well as a significant number of man-made objects, is of great interest to scientists and researchers. The present study addresses the problems of changes in the number and diversity of birds in the context of various man-made objects, such as actively operated industrial enterprises, abandoned man-made objects and places with active economic activity. Particular attention is paid to the relationship of avifauna and various biotopes located in the immediate vicinity of these objects.

Materials and methods. The presented analysis is based on data obtained as a result of route surveys conducted in May-July 2022, and includes extensive data on 11 sections of the Barents Sea coast.

Object. This review contributes to understanding the impact of man-made factors on birds and will help in the formation of strategies for the conservation and management of biodiversity in the region.

Results and conclusions. The analysis of information on the influence of large technosphere objects on the composition of the avifauna of coastal marine ecosystems is carried out. The assessment of the current state of avifauna in the areas of formation and functioning of large man-made objects has been carried out. The possibility of using avifauna as an indicator of environmental sustainability of territorial Arctic objects is evaluated. The classification of ecotopes according to the degree of intensity of their economic development is carried out.
