Jewelled spider flies of North America: a revision and phylogeny of Eulonchus Gerstaecker (Diptera, Acroceridae)

ZooKeys, 2016
The spider fly genus Eulonchus Gerstaecker is found throughout the Nearctic Region. Six species are recognized and intraspecific morphological variation is documented in several species.

Positive selection alone is sufficient for whole genome differentiation at the early stage of speciation process in the fall armyworm

BMC Evolutionary Biology, 2020
Background The process of speciation involves differentiation of whole genome sequences between a pair of diverging taxa. In the absence of a geographic barrier and in the presence of gene flow, genomic differentiation may occur when the homogenizing ...

Widespread conservation and lineage-specific diversification of genome-wide DNA methylation patterns across arthropods

bioRxiv, 2020
Cytosine methylation is an ancient epigenetic modification yet its function and extent within genomes is highly variable across eukaryotes. In mammals, methylation controls transposable elements and regulates the promoters of genes.

Validation of COI metabarcoding primers for terrestrial arthropods

PeerJ, 2019
Metabarcoding can rapidly determine the species composition of bulk samples and thus aids biodiversity and ecosystem assessment. However, it is essential to use primer sets that minimize amplification bias among taxa to maximize species recovery. Despite

What arthropod brains say about arthropod phylogeny [PDF]

Proceedings of the National Academy of Sciences, 2004
What can we learn from the brain of a single member of a species? If the brain is that of a remipede, the focus of a report by Fanenbruck et al. (1) in this issue of PNAS, the answer is something new about arthropod phylogeny. The Remipedia, discovered in 1979, are crustaceans found deep in the waters of coastal caves (2, 3). To date, twelve species of

Environmental DNA metabarcoding of wild flowers reveals diverse communities of terrestrial arthropods

Ecology and Evolution, 2019
Terrestrial arthropods comprise the most species‐rich communities on Earth, and grassland flowers provide resources for hundreds of thousands of arthropod species.

iSeq 100 for metagenomic pathogen screening in ticks

Parasites & Vectors, 2021
Background Ticks are blood-sucking ectoparasites that play a pivotal role in the transmission of various pathogens to humans and animals. In Korea, Haemaphysalis longicornis is the predominant tick species and is recognized as the vector of pathogens ...

The Phylogeny and Evolutionary History of Arthropods.

Current Biology, 2019
Arthropods are the most diverse animal phylum, and their phylogenetic relationships have been debated for centuries. With the advent of molecular phylogenetics, arthropods were found to be monophyletic and placed within a clade of molting animals, the ...

Arthropods as vertebrate predators: A review of global patterns

Global Ecology and Biogeography, 2020
Arthropod predators preying on vertebrates is generally overlooked in ecological studies, as it is not typically observed in nature and generally considered a rare event.
