Polar and brown bear genomes reveal ancient admixture and demographic footprints of past climate change
TLDR
It is demonstrated that brown bears and PBs have had sufficiently independent evolutionary histories over the last 4–5 million years to leave imprints in the PB nuclear genome that likely are associated with ecological adaptation to the Arctic environment.
An updated phylogeny and classification of Lamiaceae subfamily Lamioideae
TLDR
A taxonomic update of the Lamioideae subfamily is presented based on earlier published data as well as 71 new DNA extracts from relevant in- and outgroup taxa, and DNA sequence data from four chloroplast regions.
Complete mitochondrial genome of a Pleistocene jawbone unveils the origin of polar bear
TLDR
It is shown that the phylogenetic position of the ancient polar bear lies almost directly at the branching point between polar bears and brown bears, elucidating a unique morphologically and molecularly documented fossil link between living mammal species.
Origin of the Hawaiian endemic mints within North American Stachys (Lamiaceae).
TLDR
It is hypothesize that the Hawaiian mints may be polyploid hybrids whose reticulate genomes predate the Hawaiian dispersal event and are derived from Stachys lineages with flowers exhibiting insect- vs. bird-pollination characteristics.
Molecular phylogenetics of an aquatic plant lineage, Potamogetonaceae
TLDR
Non‐coding nuclear and plastid DNA data were used to address Potamogetonaceae relationships and accompanying issues in character evolution and biogeography, and provided a useful genetic framework from which to interpret morphological, cytological andBiogeographical evolution.
Molecular Phylogenetics, Character Evolution, and Suprageneric Classification of Lamioideae (Lamiaceae)1
TLDR
A phylogenetic analysis of Lamiaceae subfam Lamioideae based on sequences of thetrnL intron, trnL-trnF intergenic spacer, and rps16 intron of the plastid genome suggests monophyly of Lamioidesae s.l. (i.e., including Pogostemonoideae) is strongly supported, with Cymaria Benth.
New insights into evolutionary relationships within the subfamily Lamioideae (Lamiaceae) based on pentatricopeptide repeat (PPR) nuclear DNA sequences.
TLDR
This study represents the first phylogeny of subfamily Lamioideae inferred from low-copy nuclear DNA data, and shows that most lamioid tribes are corroborated, although the exact circumscription of two tribes is questioned.
The Laptev Sea walrus Odobenus rosmarus laptevi: an enigma revisited
TLDR
The mitochondrial sequence data do not support the recognition of three walrus subspecies as reciprocally monophyletic evolutionary units with independent evolutionary histories, and it is recommended that Odobenus r.
Cladogenesis and reticulation in the Hawaiian endemic mints (Lamiaceae)
TLDR
The relatively greater extent of lineage‐sorted polymorphisms in Stenogyne may indicate selective differentiation from other fleshy‐fruited taxa, perhaps through the agency of highly specialized bird pollinators that restricted gene flow with other Hawaiian mint morphotypes.
