High site fidelity does not equate to population structure for common goldeneye and Barrow's goldeneye in North America.
<p>Delineation of population structure provides valuable information for conservation and management of species, as levels of demographic and genetic connectivity not only affect population dynamics but also have important implications for adaptability and resiliency of populations and species. Here, we measure population genetic structure and connectivity across the respective ranges of two sister species of Goldeneye, Barrow's Goldeneye (<i>Bucephala islandica</i>) and Common Goldeneye (<i>B. clangula</i>). We use two different marker types: 7 nuclear microsatellite loci assayed across 229 samples and 3,678 double digest Restriction-site Associated DNA Sequencing (ddRAD-seq) loci assayed across 61 samples. First, both datasets failed to uncover genetic structure within Common or Barrow's Goldeneye, including between North American and European samples of Common Goldeneye. These results are in contrast with previous mitochondrial DNA, band recovery, and telemetry data which suggests that goldeneyes are structured across their range. We posit that the discordance between autosomal genetic markers and other data types suggests that males, possibly subadult males, may be maintaining genetic connectivity across each species' respective ranges. Next, although inter-specific brood parasitism was expected to cause some level of gene flow, we only identified a single F1 hybrid with no further evidence of contemporary or historical gene flow. Despite ddRAD-seq demographic analyses which recovered an optimum evolutionary model of split with migration (i.e., secondary contact), estimates of gene flow were <<1 migrant per generation in both directions. Together, we conclude that either strong ecological barriers or assortative mating are likely playing a role in preventing further backcrossing. Finally, demographic analyses estimated a relatively deep divergence time between Barrow's Goldeneye and Common Goldeneye of ~1.6 million years before present and that the genomes of both species have been under similar evolutionary constraints.</p>
Data from: Do environmental conditions experienced in early life affect recruitment age and performance at first breeding in common goldeneye females?
Environmental conditions experienced early in life may have long-term impacts on life history traits and reproductive performance. We investigated whether ambient temperature experienced during the first two to four weeks of life and weather severity during the first two winters affected recruitment age and relative timing of breeding in the year of recruitment in female common goldeneyes (Bucephala clangula). Our sample consisted of 141 female recruits hatched in a study population in central Finland between 1985 and 2013 and captured later as breeders. About 56% of the recruited females bred for the first time when 2 years old (range 2-6 years). Individuals facing colder ambient temperatures during the first two to four weeks posthatch or more severe winter conditions during the first two winters did not recruit at an older age. Nor did maternal characteristics, relative hatch date or nest site availability affect recruitment age. For females that recruited at 2 years old, the date of first breeding was usually late relative to the population mean that year (mean difference 6.9 days, range -7 to 21 days). Our results suggest developmental buffering enables female goldeneye ducklings to mitigate the impacts of adverse environmental conditions experienced during the first weeks of life, at least in terms of first breeding.
