Development, 2019 ABSTRACT There is now compelling evidence that many arthropods pattern their segments using a clock-and-wavefront mechanism, analogous to that operating during vertebrate somitogenesis. In this Review, we discuss how the arthropod segmentation clock generates a repeating sequence of pair-rule gene expression, and how this is converted ...

Metabarcoding of bacteria and parasites in the gut of Apodemus agrarius
Parasites & Vectors, 2022 Background The striped field mouse Apodemus agrarius is a wild rodent commonly found in fields in Korea. It is a known carrier of various pathogens. Amplicon-based next-generation sequencing (NGS) targeting the 16S ribosomal RNA (rRNA) gene is the most ...

Parasites and blood-meal hosts of the tsetse fly in Tanzania: a metagenomics study
Parasites & Vectors, 2022 Background Tsetse flies can transmit various Trypanosoma spp. that cause trypanosomiasis in humans, wild animals, and domestic animals. Amplicon deep sequencing of the 12S ribosomal RNA (rRNA) gene can be used to detect mammalian tsetse hosts, and the ...

New stiletto flies from New Caledonia (Therevidae, Agapophytinae) [PDF]
ZooKeys, 2020 Stiletto-flies (Diptera: Therevidae) are highly diverse and species-rich in Australia and New Zealand, yet relatively few species have been recorded from neighbouring Papua New Guinea, Indonesia and throughout the remainder of Oceania.

Sticky Exudates on the Inflorescences of \u3ci\u3eCirsium Discolor\u3c/i\u3e (Asteraceae) and \u3ci\u3ePenstemon Digitalis\u3c/i\u3e (Scrophulariaceae) as Possible Defense Against Seed Predators [PDF]
, 2018 From 1982 through 1987, I investigated whether sticky exudates released by Cirsium discolor and Penstemon digitalis in their inflorescences provide defense against seed predators. I tested two hypotheses: 1: Exudates directly deter seed predators, and 2:

Controls on gut phosphatisation : the trilobites from the Weeks Formation Lagerstätte (Cambrian; Utah) [PDF]
, 2012 Despite being internal organs, digestive structures are frequently preserved in Cambrian Lagerstätten. However, the reasons for their fossilisation and their biological implications remain to be thoroughly explored.

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 ...

Ectoparasitic Arthropods Collected From Some Northern Ohio Mammals [PDF]
, 2017 Ectoparasitic arthropods were collected from some fur-bearing mammals in northern Ohio. Specimens representing seven mammalian species were examined and found to collectively harbor acarines, fleas, and biting lice.
