From Photo Nature section of our site you can also download thousands images of fungi, lichens, plants and animals, made by professional Russian field biologists and geographers during their expeditions all over the Russia and former USSR republics. All objects from our collection are determined by scientist and have exact scientific name, date and place of taking picture, as well as size of the original image.
You are able to find necessary pictures using four different approach:
1) with a help of Geographic Index (all objects are separated by countries and nature geographical zones), 2) with a help of Systematic Index (all objects are separated by their systematic position),
3) with a help of Alphabetical Index (all objects are separated by their scientific Latin names according to the alphabet), and
4) with a help of Search Form (you can search scientific (Latin) names of species, genus, family, or order).
