Abstract While clones of trembling aspen (Populus tremuloides, Michx.) in the Intermountain West of North America are expected to be large, one putative genet in central Utah, identified from morphological evidence, has garnered particular attention for its size, even gaining the nickname “Pando” (Latin for “I spread”). In order to determine if a single genetic individual coincides with the morphological boundary of “Pando,” we sampled 209 stems on a 50-m grid throughout the putative clone for… Expand

Genetic and Spatial Structuring of Populus tremuloides in a Mixed-Species Forest of Southwestern Utah, USA
TLDR
The identified genets suggest a higher-than-expected level of genetic diversity in this mixed-species stand which may confer resilience to increasing climate variability and drought, and aspen regeneration in areas of both low and high adult aspen densities show that these mixed stands can support vigorous aspen populations. Expand
Clonal dynamics in western North American aspen (Populus tremuloides)
TLDR
It is concluded that recent sexual reproduction in these landscapes is a stronger contributor to standing genetic variation at the population level than the accumulation of somatic mutations, and that even some of the spatially large clones may not be as ancient as previously supposed. Expand
Clonal dynamics in western North American aspen ( Populus tremuloides )
Clonality is a common phenomenon in plants, allowing genets to persist asexually for much longer periods of time than ramets. The relative frequency of sexual vs. asexual reproduction determinesExpand
Widespread Triploidy in Western North American Aspen (Populus tremuloides)
TLDR
It is demonstrated that triploidy is highest in unglaciated, drought-prone regions of North America, where the largest clone sizes have been reported for this species, and cytotype may be a significant and previously overlooked factor in recent patterns of high aspen mortality in the southwestern portion of the species range. Expand
Outlier Stands of Quaking Aspen in the Davis Mountains of West Texas: Clone or Clones?
TLDR
Seven microsatellites were utilized to examine leaf samples from 10 widely separated stems in 10 isolated P. tremuloides individual stands within the Davis Mountains to determine the level of clonal and genetic diversity. Expand
Comparison of phenotypic and genetic clone delineation in quaking aspen, Populus tremuloides
Key messageClonal delineation at nuclear microsatellites and phenotypic traits showed high correspondence and revealed an important role of both sexual and clonal reproduction for stand geneticExpand
Cytotype differences in radial increment provide novel insight into aspen reproductive ecology and stand dynamics
TLDR
Tree-ring data collected from stems within an aspen stand near Fish Lake, Utah, is used to test for differences in stem age, population structure, growth, and response to climate. Expand
Novel insights into the genetic diversity and clonal structure of natural trembling aspen ( Populus tremuloides Michx.) populations: A transcontinental study
TLDR
It appears that species‐specific disturbance responses and post‐fire recruitment mechanisms are more important than dominant ecological factors, such as climate and fire regimes, in shaping distribution‐wide patterns of neutral genetic variation and clonal structure. Expand
Microsatellite survey reveals possible link between triploidy and mortality of quaking aspen in Kaibab National Forest, Arizona
TLDR
It is suggested that triploidy is a predisposing factor for aspen mortality in Kaibab National Forest and sites populated with putative triploids had higher mortality. Expand
Extensive Clonal Assemblies in Populus alba and Populus x canescens from the Iberian Peninsula
TLDR
A genetic analysis of the hybrid Populus x canescens and its parent species Populus alba and Populus tremula, with special emphasis in P. alba with which backcrosses frequently occur, is presented. Expand

Genetic variation and clonal distribution of quaking in the central Sierra Nevada
TLDR
Investigating genetic variability, clonal diversity, levels of differentiation, and patterns of geographic variation as measured by allozymes among 663 aspen individuals located in 82 stands from 8 watersheds throughout the western slope of the central Sierra Nevada, California found that stands that are in close proximity are not necessarily genetically similar, and can be, in fact, quite genetically distinct.

TLDR
Although the aspens are typically recognized as pioneer species, they may be more permanently part of the habitat than most of their non—clonal associates and Recognition of the clonal structure of most aspen stands is important in many aspects of research. Expand

Clonal and spatial genetic structures of aspen (Populus tremuloides Michx.)
TLDR
The results suggest that aspen spatial genetic structuring reflects the spatial patterns produced by the regeneration of discrete cohorts at different stages of succession, and as the stand gets older, the spatial distribution of aspen trees and genetic structure evolve from a structured pattern to a more random one under a gap disturbances regime.
