Book Description
The present catalogue summarizes the information on species composition and distribution of ants in Bulgaria, known until 2010 from literature and museum collections. The authors have worked intensively on Bulgarian myrmecofauna for the last 10 years. The Bulgarian myrmecofauna currently comprises 163 species from 40 genera and 6 subfamilies. The species list accounts synonyms and the respective publications they were used in, as well as all known localities in Bulgaria. Known localities are grouped by geographical regions and maps with concrete localities or regions for each species are provided. The conservation status of threatened ant species is discussed. The catalogue of Bulgarian ants may be of interest to myrmecologists, ecologists, biogeographers, conservationists and any zoological library.

Book Description
The 25 authors provide a much-needed synthesis of what is currently known about these relatives of spiders, focusing on basic conceptual issues in systematics and evolutionary ecology, making comparisons with other well-studied arachnid groups, such as spiders and scorpions. --from publisher description.

Book Description
Hemiptera (true bugs, cicadas, leafhoppers, planthoppers, aphids, scale insects, psyllids) are among the most numerous and diverse in morphology, biology, ecology and behavior insect groups, with vital ecosystems. Many of them are important in the base of the food chain. Others have economic significance as pests on fruit trees, vines, greenhouse crops and other agrocoenoses. Invasive alien species are the second most important cause of biodiversity loss in Europe and many of them belong to Hemiptera. This special issue of ZooKeys includes a collection of 26 papers presented during the 6th European Hemiptera Congress, which was held at Blagoevgrad, Bulgaria from 25th to 29th June 2012. Leading Hemiptera experts from 26 countries in four continents took part at the congress. The discussions were focused on general aspects of Hemiptera studies treating faunistics and biogeography of the Mediterranean Basin and Europe more generally as well as on taxonomy and phylogeny of Cicadomorpha, Fulgoromorpha, Heteroptera, Aphidoidea and Psylloidea; complex application of ecological, acoustic, genetic, palaeontological and behavioral methods; applied research and pest control. This special issue will be of great value for anyone interested in the biology of Hemiptera in general and of certain groups in particular, stimulating future research on this interesting group of insects.

Book Description
From single-celled organisms in Black Sea sand to endemic cave crustaceans, from mountain glacial relict insects to the most diverse bird fauna in Europe, the fauna of Bulgaria has been a subject of study for more than a century. This is the first English language survey of all vertebrate and many key invertebrate groups of Bulgaria, their faunistics, origin, geographical and ecological distribution, and conservation issues.

Book Description
Readers will perhaps be surprised to find a volume about fungi within a handbook of vegetation science. Although fungi traditionally feature in textbooks on botany, at least since Whittaker (1969), they have mostly been categorised as an independent kingdom of organisms or, in contrast to the animal and plant kingdom, as probionta together with algae and protozoa. More relevant for ecology than the systematic separation of fungi from plants is the different lifestyle of fungi which, in contrast to most plants, live as parasites, saprophytes or in symbiosis. Theoretical factors aside, there are also practical methodological considerations which favour the distinction between fungal and plant communities, as has been shown for example by Dörfelt (1974). Despite their special position the coenology of fungi has been dealt with in the handbook of vegetation science. It would be wrong to conclude that we underestimate the important differences between fungal and plant communities. The reasons for including the former are that mycocoenology developed from phytocoenology, the similarity of the methods and concepts still employed today and the close correlation between fungi and plants in biocoenoses.

Book Description
This is the first attempt to synthesize current understanding of biodiversity in the great European hot spot. A diverse group of international researchers offers perspective on biodiversity at the level of the gene, species and ecosystem, including contributions on temporal change. Biological groups include plants, mammals, spiders and humans, cave-dwelling organisms, fish, aquatic invertebrates and algae.
