Molecular phylogeny of Eastern Pacific porcelain crabs, genera Petrolisthes and Pachycheles, based on the mtDNA 16S rDNA sequence: phylogeographic and systematic implications.
TLDR
The authors' phylogenetic trees indicate that the genus Petrolisthes is divided into two main clades, reflecting morphological features, and suggests an antitropical distribution; north and south temperate species form one clade and tropical species form a second clade.About:

Linking biogeography to physiology: Evolutionary and acclimatory adjustments of thermal limits
TL;DR: Comparisons of congeneric marine invertebrates reveal that the most warm- Adapted species may live closer to their thermal tolerance limits and have lower abilities to increase heat tolerance through acclimation than more cold-adapted species.

Trade-offs in thermal adaptation: the need for a molecular to ecological integration
Hans O. Pörtner,Albert F. Bennett,Francisco Bozinovic,Andrew Clarke,Marco A. Lardies,Magnus Lucassen,Bernd Pelster,Fritz Schiemer,Jonathon H. Stillman +8 more
TL;DR: This effort illustrates the need for an overarching concept of thermal adaptation that encompasses molecular, organellar, cellular, and whole‐organism information as well as the mechanistic links between fitness, ecological success, and organismal physiology.

Fossil Calibration of Molecular Clocks and the Divergence Times of Geminate Species Pairs Separated by the Isthmus of Panama
TL;DR: Calibration of nucleotide sequence divergence rates among six pairs of geminates in the Arcidae suggests that divergence rates can be greatly overestimated when dates corresponding to final closure of the Central American Seaway are used to calibrate the molecular clocks of marine organisms.

Clustal w: improving the sensitivity of progressive multiple sequence alignment through sequence weighting, position-specific gap penalties and weight matrix choice
TL;DR: The sensitivity of the commonly used progressive multiple sequence alignment method has been greatly improved and modifications are incorporated into a new program, CLUSTAL W, which is freely available.

Confidence limits on phylogenies: an approach using the bootstrap.
TL;DR: The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters.

TL;DR: A thermostable DNA polymerase was used in an in vitro DNA amplification procedure, the polymerase chain reaction, which significantly improves the specificity, yield, sensitivity, and length of products that can be amplified.
