Phylotranscriptomics to Bring the Understudied into the Fold: Monophyletic Ostracoda, Fossil Placement, and Pancrustacean Phylogeny [PDF]

open access: yes, 2012
An ambitious, yet fundamental goal for comparative biology is to understand the evolutionary relationships for all of life. However, many important taxonomic groups have remained recalcitrant to inclusion into broader scale studies.

A new story of four Hexapoda classes: Protura as the sister to all other hexapods

open access: yesbioRxiv
Insects represent the most diverse animal group, yet previous phylogenetic analyses based on the morphological and molecular data have failed to agree on the evolutionary relationships of early insects and their six-legged relatives (together ...

Microbialite cathodoluminescence: A tool for investigating palaeoredox conditions, alteration histories and primary textures across time

open access: yesThe Depositional Record, EarlyView.
Microbialites are common throughout the rock record and key to our understanding of Earth history, yet a relatively common microscopy technique—cathodoluminescence (CL)—has not previously been leveraged to understand them. In this contribution, we examine microbialites of varying ages (modern to Proterozoic) with CL and report on the patterns and ...

Incomplete lineage sorting and long-branch attraction confound phylogenomic inference of Pancrustacea

open access: yesFrontiers in Ecology and Evolution
IntroductionThe phylogenetic relationships within Pancrustacea (including Crustacea and Hexapoda) remain elusive despite analyses using various molecular data sets and analytical approaches over the past decade.

Registro de alimentação insetívora oportunista em Artibeus lituratus (Olfers,1818) (Chiroptera, Phyllostomidae) em um parque urbano no município do Rio de Janeiro (Rio de Janeiro, Brasil)

open access: yesBiotemas, 2022
Morcegos frugívoros são comumente registrados em áreas alteradas e também nas cidades, utilizando praças e parques urbanos como área de vida. Como parte de um projeto de monitoramento de morcegos urbanos, exemplares foram capturados em um fragmento ...

The Evolution of Collembola Higher Taxa (Arthropoda, Hexapoda) Based on Mitogenome Data

open access: yesDiversity, 2022
Mitogenomes represent useful tools for investigating the phylogeny of many metazoan clades. Regarding Collembola, the use of mitogenomics has already shown promising results, but few published works include sufficient taxon sampling to study its ...

Recently Evolved, Stage‐Specific Genes Are Enriched at Life‐Stage Transitions in Flies

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
We discovered that 20%–30% of protein‐coding genes in Drosophila melanogaster and Aedes aegypti are only expressed during specific stages of development. Surprisingly, many of these stage‐specific genes are newly evolved, unique to flies and mosquitoes, shedding light on how insect development has evolved over time.

Some misconceptions or preconceived ideas on the history of the Insects

open access: yesBIO Web of Conferences, 2015
The Hexapoda is the most diverse clade of the history of life. They cannot be considered as the oldest terrestrial animals and the first Hexapoda were small apterous animals of the Devonian soil fauna, apparently not very diverse and “dominated” by ...
