Round, PD, Hansson, B, Pearson, DJ, Kennerley, PR, Bensch, S
We present compelling evidence of the continued existence of the large-billed reed warbler Acrocephalus orinus, hitherto known only from the unique type specimen collected in NW India 139 years ago....
No evidence for inbreeding avoidance in a great reed warbler population (2007)
Hansson, B, Jack, L, Christians, JK, Pemberton, JM, Åkesson, M, Westerdahl, H, ...
Inbreeding depression may drive the evolution of inbreeding avoidance through dispersal and mate choice. In birds, many species show female-biased dispersal, which is an effective inbreeding...

Knowledge of relatedness between pairs of individuals plays an important role in many research areas including evolutionary biology, quantitative genetics, and conservation. Pairwise relatedness...
We tested 74 passerine microsatellite loci for cross-amplification in the Principe seedeater (Serinus rufobrunneus), and identified 15 loci that were both polymorphic and easy to score. In a sample...

Associations between malaria and MHC genes in a migratory songbird (2005)
Westerdahl, H, Waldenström, J, Hansson, B, Hasselquist, D, Von Schantz, T, Bensch, S
Malaria parasites are a widespread and species-rich group infecting many wild populations of mammals, birds and reptiles. Studies on humans have demonstrated that genetic factors play a key role in...
Lifetime fitness of short- and long-distance dispersing great reed warblers (2004)
Hansson, B, Bensch, S, Hasselquist, D
Dispersal is of prime importance for many evolutionary processes and has been studied for decades. The reproductive consequences of dispersal have proven difficult to study, simply because it is...
Breeding synchrony does not affect extra-pair paternity in great reed warblers (2004)
Arlt, D, Hansson, B, Bensch, S, Von Schantz, T, Hasselquist, D
Breeding synchrony is hypothesised to influence the occurrence and frequency of extra-pair fertilisations (EPFs) in birds irrespective of the social mating system. The two proposed hypotheses make...
Do female great reed warblers seek extra-pair fertilizations to avoid inbreeding? (2004)
Hansson, B, Hasselquist, D, Bensch, S
Females of many species mate with several males. According to a recent hypothesis, female promiscuity serves to avoid inbreeding. We tested this hypothesis in a polygynous bird, the great reed...
Marker-based relatedness predicts egg-hatching failure in great reed warblers (2004)
I examine the relationship between reproductive success and marker-based relatedness (MBR; inferred from variation at 21 microsatellite loci) of pair-mates in a semi-isolated population of great reed...
Observation of a ZZW female in a natural population: implications for avian sex determination (2004)
Arlt, D, Bensch, S, Hansson, B, Hasselquist, D, Westerdahl, H
Avian sex determination is chromosomal; however, the underlying mechanisms are not yet understood. There is no conclusive evidence for either of two proposed mechanisms: a dominant genetic switch or...
Hansson, B, Westerdahl, H, Hasselquist, D, Åkesson, M, Bensch, S
Heterozygosity-fitness correlations (HFCs) at noncoding genetic markers are commonly assumed to reflect fitness effects of heterozygosity at genomewide distributed genes in partially inbred...
Between-year variation of MHC allele frequencies in great reed warblers: selection or drift? (2004)
Westerdahl, H, Hansson, B, Bensch, S, Hasselquist, D
The major histocompatibility complex (MHC) genes are extremely polymorphic and this variation is assumed to be maintained by balancing selection. Cyclic interactions between pathogens and their hosts...

We report on the second case of a reed warbler x great reed warbler hybrid (Acrocephalus scirpaceus and A. arundinaceus). The bird was captured during a standardised ringing session in Belgium in...
Heritability of dispersal in the great reed warbler (2003)

In patchily distributed species dispersal connects local populations into metapopulations. Reliable quantifications of dispersal are therefore crucial to understanding the population dynamics and...
Microsatellite diversity predicts recruitment of sibling great reed warblers (2001)
Hansson, B, Bensch, S, Hasselquist, D, Åkesson, M
Inbreeding increases the level of homozygosity, which in turn might depress fitness. In addition, individuals having the same inbreeding coefficient (e.g. siblings) vary in homozygosity. The...

Hansson, B, Bensch, S, Hasselquist, D, Lillandt, BG, Wennerberg, L, Von Schantz, T
Genetic similarity within pairs of individuals was examined using both 10 polymorphic microsatellite loci and multi-locus DNA fingerprinting profiles in a semi-isolated population of great reed...
The quality and the timing hypotheses evaluated using data on great reed warblers (2000)
Hansson, B, Bensch, S, Hasselquist, D

Patterns of nest predation contribute to polygyny in the Great Reed Warbler (2000)
Hansson, B, Bensch, S, Hasselquist, D
According to the polygyny threshold model, females are compensated for the cost of sharing a territory with other females by breeding in territories of higher quality than those of monogamously mated...
