Main Results

A combination of conventional and cutting-edge biological research methods is being used to study quantitative and qualitative aspects of the fauna and hydrobionts of Armenia, assess their current state and identify existing and potential threats. Special emphasis is placed on examining endangered and invasive species, as well as species holding potential for biological control, animal and plant parasites and agricultural pests:

  • A comparative evaluation and compilation of data have been performed on osteological material gathered from archaeological sites in the northwestern Armenia dating back to the 3rd-1st millennium BC. Both qualitative and quantitative changes have been observed in the mammalian fauna, suggesting shifts in the region’s ecosystems and climate.
  • Over the course of the past 10 years, approximately 150 new species have been discovered for the arthropod fauna of Armenia and 4 species new for science have been described. Based on the most recent data, the vertebrate fauna, amounts to a total of 572 species. A subspecies of Common Crane – Grus grus archibaldi new for science has been described from Armenia. An extensive amount of data has been collected to update the Red Data Book of Animals of Armenia․ A taxonomic list and species accounts for 29 insect species of Armenia have been prepared and submitted to the Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN) for the IUCN Red List. The Caucasian Biodiversity Barcode Platform has been enriched with DNA sequencing results for nearly 2000 samples of terrestrial and aquatic animals of Armenia.
  • Studies on phenotypic and genotypic changes in fish and amphibian populations occurring in habitats contaminated with heavy metals were conducted.
  • First research efforts in the last 50 years were undertaken to collect data on the waterbird diversity, occurrence status, habitat suitability and the extent of human pressure within the restricted military border strip of the mid reaches of the Araks River.
  • Research was held into fauna, ecological and biological characteristics of the most pathogenic helminths and ticks serving as vectors of parasitic diseases:

A total of 220 species of nematodes and acanthocephalans have been identified in Armenia. New taxonomic and biological classifications for tapeworms have been proposed. 
Genotyping of pathogens which cause zoonotic diseases such as echinococcosis, toxoplasmosis, and dirofilariasis was performed for the first time in Armenia and revealed the prevalence of pathogenic strains associated with these diseases in our country.
Widely distributed ecto- and endoparasitic nematodes have been identified in fruit trees, conifers and grapevines, including pathogenic phytonematodes that act as vectors of viruses in both wild and cultivated plants.

  • The rich scientific collection funds of the Center and the Zoological Museum have been enriched with new materials and exhibits, a corner showcasing live nature has also been created. 
  • A study of the hydroecosystems of Armenia is being carried out:

Since 2010 studies were carried out to examine the condition of spawning grounds for endemic fish species in Lake Sevan, and assess the forage base of the fish. 
Causes of eutrophication in Lake Sevan resulting from morphometric changes have been identified. 
The genetic diversity of planktonic bacteria in Lake Sevan has been studied for the first time. 
Monitoring and assessment of the ecological status of the lake is underway. 
Monitoring of hydrobiological parameters in transboundary rivers has been completed and their ecological status has been assessed. 

Results of applied research

  • Proposals submitted to the RA Ministry of Environment refer to management of 

aquatic ecosystems and biodiversity resources; 
revision of fish harvesting methods; 
regulation and effective control of river channels; 
requirements and management principles applied to industrial sites involved in the exploitation of hydrobionts; 
restoration of industrial stocks, management of fish and crayfish resources.

  • A one-dimensional (1D) model for assessing the thermal regime of Lake Sevan has been developed.
  • As a result of continuous high-frequency measurements, a large volume of water quality data has been collected in Lake Sevan. 
  • An assessment was undertaken to measure the impact of small hydropower plants constructed on the Arpa River and its tributaries, Herher and Yeghegis. The most effective approaches for measuring the impact of these small hydropower plants have been proposed. 
  • A system of multi-parameter indicators to assess the condition of ecological status in rivers has been developed for several major rivers in Armenia.
  • Upon commission by the RA Ministry of Environment the current state of the main game species populations in Armenia has been assessed for 2020-2023. Diversity and population numbers of game species was estimated. Distribution ranges, hunting bags of harvestable game species and dates of hunting seasons were determined.
  • Measures have been developed for the treatment and prevention of various parasitic diseases in livestock and cultivated plants, including the environmentally-friendly strategies for controlling agricultural pests:

Proposals were developed and submitted to the RA Ministry of Agriculture to control lung and gastrointestinal helminthiasis in sheep and goats in the foothill zones of Armenia.
Extracts derived from different plant species were developed and tested to assess their insecticidal and acaricidal properties and effectiveness.
A methodology has been developed to maintain the laboratory population of an effective biological control agent - the predatory mite Phytoseiulus persimilis at low temperatures.

International Activity
  • In 1996 Russian-Armenian Joint Scientific Experimental Center (RA JSEC) has been established by agreement between the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences and the Institute of Zoology of the SCZH NAS RA and located in Nor Artamet village of Kotayk marz. This is the first joint scientific unit in entire NIS, which allowed re-establishing of lost collaboration between NAS RA and RAS.  The JSEC serves as a base for experimental Parasitology and other zoological studies. Here the collaborative (with Russian specialists) efforts in experimental studies dedicated to important issues to biodiversity, zoology and parasitology, and tests of effective and environmentally safe methods of agricultural pest control are implemented. Тhe results of joint research have great scientific and practical importance and are presented in more than 70 national, regional and international peer-reviewed publications, including three monographs.
  • According to the agreement signed in 1993 between the Institute of Biology of Inland Waters after I. D. Papanin of the Russian Academy of Sciences and the Institute of Hydroecology and Ichthyology of the National Academy of Sciences of the Republic of Armenia on scientific cooperation the program "Joint Study of the current ecological state of Lake Sevan” is carried out and annually "Armenian-Russian joint scientific expedition" is organized in the Lake Sevan basin. The long-term research results are summarized in 2 collective monographs.
  • Were organized:

3 international conferences “Biological Diversity and Problems of Fauna Protection” (2011, 2014, 2017) (on the initiative of the National Center of Zoology and Hydroecology of the NAS RA, together with the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences and the American University of Armenia);
