A high density linkage map enables a second generation collared flycatcher genome assembly and reveals the pattern of avian recombination rate variation and chromosomal evolution.
(Journal article; Peer reviewed, 2014-06-17)Detailed linkage and recombination rate maps are necessary to use the full potential of genome sequencing and population genomic analyses. We used a custom collared flycatcher 50 K SNP array to develop a high-density linkage ... -
Are immigrants outbred and unrelated? Testing fundamental assumptions in a wild metapopulation
(Journal article; Peer reviewed, 2021) -
Artificial size selection experiment reveals telomere length dynamics and fitness consequences in a wild passerine
(Peer reviewed; Journal article, 2022)Telomere dynamics could underlie life-history trade-offs among growth, size and longevity, but our ability to quantify such processes in natural, unmanipulated populations is limited. We investigated how 4 years of artificial ... -
Comparative transcriptomics reveals domestication‐associated features of Atlantic salmon lipid metabolism
(Peer reviewed; Journal article, 2020)Domestication of animals imposes strong targeted selection for desired traits but can also result in unintended selection due to new domestic environments. Atlantic salmon was domesticated in the 1970s and has subsequently ... -
Decomposing demographic contributions to the effective population size with moose as a case study
(Peer reviewed; Journal article, 2020)Levels of random genetic drift are influenced by demographic factors, such as mating system, sex ratio and age structure. The effective population size (N e) is a useful measure for quantifying genetic drift. Evaluating ... -
Decomposing demographic contributions to the effective population size with moose as a case study
(Journal article; Peer reviewed, 2020)Levels of random genetic drift are influenced by demographic factors, such as mating system, sex ratio and age structure. The effective population size (Ne) is a useful measure for quantifying genetic drift. Evaluating ... -
Dispersal in a house sparrow metapopulation: An integrative case study of genetic assignment calibrated with ecological data and pedigree information
(Peer reviewed; Journal article, 2021)Dispersal has a crucial role determining ecoevolutionary dynamics through both gene flow and population size regulation. However, to study dispersal and its consequences, one must distinguish immigrants from residents. ... -
Effects of population characteristics and structure on estimates of effective population size in a house sparrow metapopulation
(Journal article, 2014)Effective population size (Ne) is a key parameter to understand evolutionary processes and the viability of endangered populations as it determines the rate of genetic drift and inbreeding. Low Ne can lead to inbreeding ... -
Genetic architecture and heritability of early-life telomere length in a wild passerine
(Peer reviewed; Journal article, 2021)Early-life telomere length (TL) is associated with fitness in a range of organisms. Little is known about the genetic basis of variation in TL in wild animal populations, but to understand the evolutionary and ecological ... -
Genetic variation and structure of house sparrow populations: is there an island effect?
(Journal article; Peer reviewed, 2013)Population genetic structure and intrapopulation levels of genetic variation have important implications for population dynamics and evolutionary processes. Habitat fragmentation is one of the major threats to biodiversity. ... -
Inferences of genetic architecture of bill morphology in house sparrow using a high-density SNP array point to a polygenic basis
(Journal article; Peer reviewed, 2018)Understanding the genetic architecture of quantitative traits can provide insights into the mechanisms driving phenotypic evolution. Bill morphology is an ecologically important and phenotypically variable trait, which is ... -
A paleogenomic investigation of overharvest implications in an endemic wild reindeer subspecies
(Peer reviewed; Journal article, 2024)Overharvest can severely reduce the abundance and distribution of a species and thereby impact its genetic diversity and threaten its future viability. Overharvest remains an ongoing issue for Arctic mammals, which due to ... -
Sensitivity analysis of effective population size to demographic parameters in house sparrow populations
(Journal article, 2017)The ratio between the effective and the census population size, (math formula), is an important measure of the long-term viability and sustainability of a population. Understanding which demographic processes that affect ... -
Signatures of genetic adaptation to extremely varied Australian environments in introduced European house sparrows
(Journal article; Peer reviewed, 2018)Due to its history of multiple introductions to novel environments worldwide, the house sparrow has been used as a model species to study local adaption in invasive avian species. New genomic resources such as a custom ...
