Sequencing and analysis of the complete mitochondrial genome of Habrobracon hebetor (Hymenoptera: Braconidae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
We determined the complete mitochondrial genome sequence of Habrobracon hebetor (Say). The complete mitogenome sequence of H. hebetor was observed to be a circular molecule 15,708 bp long and consists of 13 protein-coding genes (PCG), 2 ribosomal RNA ...

Pattern-based phylogenetic distance estimation and tree reconstruction [PDF]

open access: yes, 2006
We have developed an alignment-free method that calculates phylogenetic distances using a maximum likelihood approach for a model of sequence change on patterns that are discovered in unaligned sequences.

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 ...

Phylogenetic structure and formation mechanism of shrub communities in arid and semiarid areas of the Mongolian Plateau [PDF]

open access: yes, 2019
The mechanisms of species coexistence within a community have always been the focus in ecological research. Community phylogenetic structure reflects the relationship of historical processes, regional environments, and interactions between species, and ...

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.

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.
