All potential myrmecochorous plants of the Czech Republic have been detected from different published sources. My study aims to describe common traits of myrmecochorous plants of the Czech flora. One of myrmecochores, lousewort (Pedicularis sylvatica), was chosen for the purpose of finding peaks in seed removal by a Myrmica scabrinodis ant species during a day and year

Forest ants of the genus Formica are legally protected animals. With the environmental services they provide, ensure ecological stability of forest ecosystem and are an important part of ecosystem. This work was focused on the study of ecological linkages (trofobiosis, myrmecochory and myrmecofily) and mapping damage nesting by woodpecker and wild pigs. Their destructive activities in the studied area are very high. The work also oriented on gaining a new approach to protect the ants of the genus Formica, which is based on the Red List of endangered species in the Czech Republic. Existing species protection is extended to protect the environment and the creation of a comprehensive protection.

Abandoned industrial-waste deposits (incl. fly ash or tailings ponds) represent very specific and mostly extreme habitat conditions. They offer unique opportunity to study primary succession in cultural landscape. Substrate of the material deposited here shows extreme properties, such as low pH, overheating of the open surface, salinization etc. The aim of this work is to map the colonization of different successional stages of vegetation by ants after years of abandonment of ore-waste deposits in Chvaletice (Eastern Bohemia, CR) and to compare the present state with analogous study made in 2001. Particular aims of both studies (Jarešová 2001, and present study, 2011-12) is to test the influence of ants on vegetation succession. During the years 2011-2012 several prospections were made to record species diversity of ants. On the surface plateau of the sedimentation basin two types of habitats were chosen - the areas with present ant nests and the other areas without them. Each of both types of habitats exhibits different plant species richness: separately the species-area curves were constructed and explained. Three dominant ant species of different size categories present on sedimentation basin were selected for experimental offering of plant seeds, Formica pratensis, Lasius niger, Tetramorium...
