It is generally recognized that environmental pollution with agrotechnical substances the major problem for conservation of biological diversity and human food security. However, their use cannot be completely excluded. Of particular importance are modern rodenticides, i.e. superwarfarins, designed to reduce numbers rodents damaging agriculture, destroy animals. these poisons highly toxic passe...

Introduction. Historical analysis is extremely important in assessing the development and achievements of scientific schools centres. This especially true concerning research centres operated continuously from end 19th century to almost first quarter 21st century, which include Federal Scientific Center for Hygiene (FSCH), named after F.F. Erisman Service Supervision Consumer Rights Protection ...

Growing a large mass of hydrobionts in limited area (cage fish farming) entails local increase the load on ecosystem from additional organic matter. In connection with high growth rates development cage farms various open natural water bodies, it is necessary to improve system for monitoring their impact aquatic biocenoses. The quality surface waters and bottom sediments Ermakovskiy Bay Ust-Kam...

The study is the first attempt to generalize data on burrow biocenoses of great gerbil (Rhombomys opimus (Lichtenstein, 1823)) in region persistent plague epizootics lowland part Karakum Desert (Southern Turkmenistan). material was collected May, November, and December 1987–1988 using trapping cylinders residential non-residential colonies gerbil.

This article presents an overview of the characteristics pointing out deterioration epidemiological situation during military conflicts and anthropogenic disasters drawing form latest literature. There are particular conditions that can provoke emergencies, among them conflicts, natural disasters, humanitarian crises, man-made use biological weapons, particularly within context Russian invasion...

The fine characterization of the substrate is a baseline to thoroughly investigate relations between organisms and their biotopes. Cutting edge spatial technologies now provide access accurate information on biotopes biocenoses both in terrestrial marine environments. Photogrammetry one them has recently been applied submarine environments especially shallow clear water. In this study, we inves...

The continental shelf and submarine canyon off Cap de Creus (NW Mediterranean) were declared a Site of Community Importance (SCI) within the Natura 2000 Network in 2014. Implementing an effective management plan to preserve its biological diversity monitor evolution through time requires detailed characterization benthic ecosystem. Based on 60 underwater video transects performed between 2007 2...
