Candidate gene polymorphisms for behavioural adaptations during urbanization in blackbirds
TLDR
The results indicate that behavioural traits related to harm avoidance and associated with the SERT polymorphism experience selection pressures during most blackbird urbanization events, and these events appear to be influenced by homogeneous adaptive processes in addition to previously reported demographic founder events.
Behaviour‐related DRD4 polymorphisms in invasive bird populations
TLDR
This work sequenced a candidate region for neophilic/neophobic and activity behaviour – the complete exon 3 of the DRD4 gene – in 100 Yellow‐crowned bishops from two invasive populations in Spain and Portugal and identified two synonymous DRD 4 SNPs that explained on average between 11% and 15% of the phenotypic variance in both populations.
Search for informative polymorphisms in candidate genes: clock genes and circadian behaviour in blue tits
TLDR
Two strategies to search for likely functional polymorphisms in candidate genes in a bird species that has been intensively studied by behavioural and population ecologists, the blue tit Cyanistes caeruleus, showed high success rates.
Sources of intraspecific variation in sleep behaviour of wild great tits
Ecologists have recently begun to recognize sleep as a behaviour that is important in animal ecology. The first steps have been taken to characterize sleep in free-living birds, but it is unclear to
Avian genome evolution: insights from a linkage map of the blue tit (Cyanistes caeruleus)
TLDR
There was highly conserved synteny between blue tit and chicken with the exception of a split on chromosome 1, potential splits on chromosome 4 and the translocation of two markers from chromosome 2 and 3, respectively, to chromosome 5.
Erratum to: Search for informative polymorphisms in candidate genes: clock genes and circadian behaviour in blue tits
TLDR
Two strategies to search for likely functional polymorphisms in candidate genes in a bird species that has been intensively studied by behavioural and population ecologists, the blue tit Cyanistes caeruleus, showed high success rates.
Temperature affects frequency but not rhythmicity of nocturnal awakenings in free-living great tits, Parus major
TLDR
It is suggested that short-duration awakenings elicited primarily during the first part of the night may not be regulated by an ultradian biological clock, and may respond directly to current environmental conditions, such as the risk environment.
Testing for associations between candidate genes for circadian rhythms and individual variation in sleep behaviour in blue tits
TLDR
This study investigated the phenotypic sleep correlates of eleven previously described polymorphisms in seven candidate genes within a free-living blue tit Cyanistes caeruleus population and detected associations between four single nucleotide polymorphisms and three of the nine tested sleep parameters representing temporal organization.
ITS Deployment and Improvements in Smaller Cities: Minnesota Case Studies
Minnesota is widely known for not only its great lakes, but also for its metropolitan area including the cities of Minneapolis and St. Paul. With combined populations of more than 2 million
SLAR reconnaissance, Mimika-Eilanden Basin, Southern Trough of Irian Jaya. [in the Pacific Ocean]
The SLAR was obtained in early April 1973 by means of an AN/APQ-97 K-band brute-force system. The flight strips are all north-look, with ground-range display, and 60% overlap. The interpretation was
