The genome of a songbird
This work shows that song behaviour engages gene regulatory networks in the zebra finch brain, altering the expression of long non-coding RNAs, microRNAs, transcription factors and their targets and shows evidence for rapid molecular evolution in the songbird lineage of genes that are regulated during song experience.
Towards unbiased parentage assignment: combining genetic, behavioural and spatial data in a Bayesian framework
A Bayesian approach is presented that simultaneously estimates the parentage of a sample of individuals and a wide range of population‐level parameters in which it is interested and increases the power of parentage assignment, reduces bias in parameter estimation, and accurately evaluates uncertainty in both.
Noninvasive genetic tracking of the endangered Pyrenean brown bear population
Comprehensive knowledge of endangered small populations of mammals can be obtained using noninvasive genetic sampling and it is suggested that managers consider population augmentation using only females to preserve the remaining Pyrenean gene pool and increase genetic diversity.
Single-locus and multilocus DNA fingerprinting.
Using spatial Bayesian methods to determine the genetic structure of a continuously distributed population: clusters or isolation by distance?
It is shown that Bayesian clustering methods can overestimate genetic structure when analysing an individual-based data set characterized by isolation by distance, which could lead to the erroneous delimitation of management or conservation units.
Extra-pair paternity results from female preference for high-quality males in the blue tit
Evidence is presented that such an asymmetry is indeed caused by female behaviour, and that 'attractive' males do not suffer lost paternity, survive better and recruit more young, and the results support the genetic quality hypothesis.
Reliable microsatellite genotyping of the Eurasian badger (Meles meles) using faecal DNA
In a study of 53 faeces sampled from three social groups over 10 days, it is found that direct enumeration could not be used to estimate population size, but that the application of mark–recapture models has the potential to provide more accurate results.
Contrasting levels of extra-pair paternity in mainland and island populations of the house sparrow (Passer domesticus): is there an «island effect»?
The analysis of the genetic mating system of two populations of the house sparrow and uses the results from four other populations to test existing hypotheses using an intra-specific comparative approach to find no effect of breeding density and genetic variation on the level of extra-pair paternity.
Extra-pair paternity and intraspecific brood parasitism in wild zebra finches Taeniopygia guttata, revealed by DNA fingerprinting

Behavioural observations show that EPP occurs through extra-pair copulation rather than rapid mate switching in a wild population of zebra finches, and is discussed in the light of what is known about the fertile period and sperm precedence patterns in this species.
DNA fingerprinting in birds
It is shown here that human minisatellite-derived probes also detect highly variable regions in bird DNAs and it is concluded that house sparrow DNA fingerprints are analagous to those of humans.
