Special issues

At irregular intervals, the editorial staff publishes special issues with content on a specific topic.

These special issues often have a great scientific value and are printed in a larger edition than normal for Entomologisk Tidskrift in order to be sold as reference literature.

All of Sweden's lice in one volume

The head lice are not the only lice species in Sweden, but there are many more with interesting biology. The whole of Sweden's fauna of animal lice (Phtiraptera) is summarized in this book, which is based on a doctoral thesis within the Swedish Taxonomy Initiative which the main author Daniel Gustafsson has completed. There are a total of 322 species of lice in the country. They live on everything from song larks and water voles to cattle and humans. The book contains identification keys for all species. You will also find checklists on which hosts the different lice live on and vice versa - information on which species of lice can be found on different hosts. For those who want to delve further into the subject, the 473 references listed at the end are a goldmine. The majoroity of the volume is written in English.

Longhorn beetles in Sweden

Based on 57000 records of longhorn beetles (Cerambycidae), the distribution and population levels over the last 200 years of all 118 species of longhorn beetles in Sweden are analysed. Data were gathered from 1400 insect collectors and published records. Special attention is drawn to the trends of the species, and whether increases or decreases can be attributed to changes in land use. Several new innovative methods are used to account for the probable biases that occur with records from natural history collections. In the ?rst part of the book the strength and weaknesses of the data and analyses are presented thoroughly. After that each species is presented with population trend and distribution trends presented graphically (see below). Finally, the overall conclusions of the study are drawn. As an Appendix, phenologic data of the species are presented. The book is written in English. Click here to read the information flyer.
