TL;DR: Treatment of gaps varies widely from secondarily mapping gaps onto the tree inferred from base characters to uniformly applied method of treating gaps, which is lacking in sequence-based phyloge?

TL;DR: A new database on species-trait composition of North American lotic insects is created and some ideas about how specific trait linkages, statistical correlations among traits, and evolutionary lability of traits can be used in combination with a mechanistic understanding of trait response along environmental gradients to select robust traits useful for a more predictive community ecology are concluded.

TL;DR: A large collaborative effort has yiel(led a comprehensive study of the phylogeny and a new suhfanilial classification of the grass family (Poaceae/Graminieae) and 1 new subfamily (Danthonioideae) is proposed.

TL;DR: This study used an empirical example based on 100 mitochondrial genomes from higher teleost fishes to compare the accuracy of parsimony-based jackknife values with Bayesian support values, and found that the higher BayesianSupport values are inappropriate and should not be interpreted as probabilities that clades are correctly resolved.

TL;DR: It is asserted that similarity is the appropriate homology criterion for sequence alignment, as it is with morphology, and the severity of this test is compromised when congruence with other characters is favored when selecting among alignment parameters.
