Abstract

Hybridization is a significant threat for endangered species and could potentially even lead to their extinction. This concern applies to the globally vulnerable Greater Spotted Eagle Aquila clanga, a species that co-occurs, and potentially interbreeds, with the more common Lesser Spotted Eagle Aquila pomarina in a vast area of Eastern Europe. We applied single nucleotide polymorphism (SNP) and microsatellite markers in order to study hybridization and introgression in 14 European spotted eagle populations. We detected hybridization and/or introgression in all studied sympatric populations. In most regions, hybridization took place prevalently between A. pomarina males and A. clanga females, with introgression to the more common A. pomarina. However, such a pattern was not as obvious in regions where A. clanga is still numerous. In the course of 16 years of genetic monitoring of a mixed population in Estonia, we observed the abandonment of A. clanga breeding territories and the replacement of A. clanga pairs by A. pomarina, whereby on several occasions hybridization was an intermediate step before the disappearance of A. clanga. Although the total number of Estonian A. clanga × A. pomarina pairs was twice as high as that of A. clanga pairs, the number of pairs recorded yearly were approximately equal, which suggests a higher turnover rate in interbreeding pairs. This study shows that interspecific introgressive hybridization occurs rather frequently in a hybrid zone at least 1700-km wide: it poses an additional threat for the vulnerable A. clanga, and may contribute to the extinction of its populations.

Abstract

The titles reviewed in this section of Ibis are available for reference at the Alexander Library of the Edward Grey Institute of Field Ornithology, Department of Zoology, South Parks Road, Oxford, UK. The library is open to BOU members, Monday to Friday (09:00–17:00 h). Please write or telephone (+44 (0)1865 271143) prior to your visit to ensure the library is open. The aim of the Alexander Library is to build up a comprehensive collection of literature as a service to ornithologists. Its holdings include an extensive range of periodicals and a large number of reprints drawn from many sources: additional reprints of readers’ papers are always welcome. The library has always greatly benefited from its close relationship with the BOU. For a number of years, all journals received in exchange for Ibis have been deposited in the library, and through the generosity of reviewers, most of the books sent for review. In return, as a service to readers, this review section of Ibis is organized and edited by Michael G. Wilson and Professor Ben Sheldon of the Edward Grey Institute, with the help of a panel of contributors. They are always grateful for offers of further assistance with reviewing, especially with foreign language titles. Part of the cost of this book review section has been subsidized by Subbuteo Natural History Books. Subbuteo are an international mail-order book company stocking over 2000 titles covering all natural and environmental sciences. They can also source titles from around the world. Titles reviewed here can be ordered from Subbuteo and payment can be accepted by credit card or cheques in £/$. Postage, packing and insurance is £1.99 per order.

Abstract

Colour ringing of the Spotted Eagles (Aquila pomarina, Aquila clangaand their hybrids) in Europe - a reviewDuring the years 2000-2008 1377 Spotted Eagles (SE) (Aquila pomarina, Aquila clangaand their hybrids) have been colour ringed in Europe. Out of these, 1303 (94.6 %) were young birds and 74 (5.4 %) were adults. Out of the total, 1290 (93.7 %) were the Aquila pomarinaLesser Spotted Eagles (LSE) - 1229 (95.3 %) young and 61 (4.7 %) adults, 50 (3.6 %) were the Aquila clangaGreater Spotted Eagles (GSE) - 44 (88.0 %) young and 6 (12.0 %) adults and 37 (2.7 %) were the Aquila pomarinax Aquila clangahybrids (LSE x GSE) - 30 (81.1 %) young and 7 (18.9 %) adults. With respect to the individual European countries the following SE species and numbers were ringed: Slovakia 636 (46.2 %), Poland 333 (24.2 %), Estonia 153 (11.1 %), Germany 116 (8.4 %), Lithuania 68 (4.9 %), Latvia 45 (3.3 %) and Belarus 26 (1.9 %). In the article authors presents a review on Spotted Eagle colour ringing programmes running in individual European countries.
