- Fler hjärtstartare behövs, men konceptet behöver utvecklas. Vi måste dessutom finna nya sätt att mobilisera hjärtstartare till platsen för hjärtstoppet.

Species limits in Acrocephalus and Hippolais warblers from the Western Palearctic
- 2004

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- The taxonomic affiliations within the genera [Acrocephalus] and [Hippolais] have long been a matter for debate. Recent molecular and behavioural studies have provided a wealth of new data which can be used to analyse the evolutionary relationships of the Palearctic taxa in these genera. In this paper, we make a series of recommendations for changes in species limits, highlight some problem areas and discuss situations where more research is needed.

Species limits in the Red-breasted Flycatcher
- 2005
-
Ingår i: British Birds. - 0007-0335. ; 98:10, s. 538-541
-
Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Traditionally, the Red-breasted Flycatcher [Ficedula parva] has been treated as a polytypic species with two subspecies: the western [parva] and the eastern [albicilla]. These taxa show clear differences in morphology and vocalisations and are diagnosably distinct, probably in both sexes and at all ages. There are striking differences in moult patterns between the two forms, and DNA-sequence data indicate that they are genetically divergent. It is clear that [parva] and [albicilla] are independent evolutionary lineages that are genetically distinct and fulfil the criteria for species recognition. It is recommended that they are treated as separate species, Red-breasted Flycatcher [F. parva] and Taiga Flycatcher [F. albicilla].
