Coming to America: Multiple Origins of New World Geckos [PDF]

open access: yes, 2011
Geckos in the Western Hemisphere provide an excellent model to study faunal assembly at a continental scale. We generated a time-calibrated phylogeny, including exemplars of all New World gecko genera, to produce a biogeographic scenario for the New ...

Choreography of silk spinning by webspinners (Insecta: Embioptera) reflects lifestyle and hints at phylogeny [PDF]

open access: yes, 2016
Silk spinning defines the morphologically constrained embiopterans. All individuals spin for protection, including immatures, adult males and the wingless females. Enlarged front tarsi are packed with silk glands and clothed with ejectors.

Sequencing and analysis of the complete mitochondrial genome of Changeondelphax velitchkovskyi (Hemiptera: Fulgoroidea)

open access: yesMitochondrial DNA. Part B. Resources, 2018
We determined the complete mitochondrial genome sequence of Changeondelphax velitchkovskyi (Melichar ). The complete mitogenome sequence of C. velitchkovskyi was observed to be a circular molecule 16,449 bp long and consists of 13 protein-coding genes ...

Comparative Genome Analysis and Phylogenetic Relationship of Order Liliales Insight from the Complete Plastid Genome Sequences of Two Lilies (Lilium longiflorum and Alstroemeria aurea)

open access: yesPLoS ONE, 2013
Monocots are one of the most diverse, successful and economically important clades of angiosperms. We attempt to analyse the complete plastid genome sequences of two lilies and their lengths were 152,793bp in Lilium longiflorum (Liliaceae) and 155,510bp ...

THE SYSTEMATICS AND PHYLOGENETIC RELATIONSHIPS OF VETULICOLIANS

open access: yesPalaeontology, 2007
Abstract: Vetulicolians have variously been considered to be unusual arthropods, stem‐group deuterostomes or relatives of the tunicates. They are known from a number of Cambrian Lagerstätten, and are particularly diverse in the Chengjiang biota of Yunnan Province, China.

Analysis of a data matrix and a graph: Metagenomic data and the phylogenetic tree [PDF]

open access: yes, 2011
In biological experiments researchers often have information in the form of a graph that supplements observed numerical data. Incorporating the knowledge contained in these graphs into an analysis of the numerical data is an important and nontrivial task.
