Can the Site-Frequency Spectrum Distinguish Exponential Population Growth from Multiple-Merger Coalescents?
TLDR
Estimates of statistical power indicate that exponential and algebraic growth can indeed be distinguished from multiple-merger coalescents, even for moderate sample sizes, if the number of segregating sites is high enough.

Exome sequencing of geographically diverse barley landraces and wild relatives gives insights into environmental adaptation
TLDR
After domestication, during a process of widespread range extension, barley adapted to a broad spectrum of agricultural environments and appears to have substantially contributed to range-wide ecogeographical adaptation, but many factors key to regional success remain unidentified.

Targeted re-sequencing of five Douglas-fir provenances reveals population structure and putative target genes of positive selection
TLDR
To characterize genome-wide levels of genetic diversity in coding regions and to identify genes involved in local adaptation, targeted sequence capture was used to re-sequence 72 trees representing one interior and four coastal provenances of Douglas-fir.

TLDR
This article gives a more general construction of time-changed Λ - n -coalescents as limits of specific Cannings models with rather arbitrary time changes.

Multiple Merger Genealogies in Outbreaks of Mycobacterium tuberculosis
TLDR
Test whether multiple merger coalescents (MMC), a class of models that allow for large variation in reproductive success among lineages, are more appropriate models to study Mycobacterium tuberculosis populations and outbreaks found that MMC had a better fit compared to the Kingman coalescent for ten of the eleven data sets.

On the number of allelic types for samples taken from exchangeable coalescents with mutation
Let K n denote the number of types of a sample of size n taken from an exchangeable coalescent process (Ξ-coalescent) with mutation. A distributional recursion for the sequence (K n ) n∈ℕ is derived.…

Genealogical Properties of Subsamples in Highly Fecund Populations
TLDR
The results indicate how ’informative’ a subsample is about the properties of the larger complete sample, how much information is gained by increasing the sample size, and how the ‘informativeness’ of the subsample varies between different coalescent processes.

Distinguishing coalescent models - which statistics matter most?
TLDR
A random forest based Approximate Bayesian Computation is used to disentangle the effects of different statistics on distinguishing between various classes of genealogy models and a new statistic, the minimal observable clade size, is introduced to inferring whether genealogies feature multiple mergers.
