Feather mites play a role in cleaning host feathers: New insights from DNA metabarcoding and microscopy

open access: yesMolecular Ecology, 2018
Parasites and other symbionts are crucial components of ecosystems, regulating host populations and supporting food webs. However, most symbiont systems, especially those involving commensals and mutualists, are relatively poorly understood.

A new Eocene free-living cheyletid mite from Baltic amber [PDF]

open access: yesActa Palaeontologica Polonica, 2016
A new species of predaceous mite, Cheletomimus (Hemicheyletia) crinitus sp. nov. (Acariformes: Cheyletidae), is described from Eocene Baltic amber based on a fossil female. Among species of the genus, it belongs to the C.

Case report: Parasitism of Ornithonyssus bursa (Macronyssidae) in humans in the Taquari River Valley region, southern Brazil

open access: yesActualidades Biológicas, 2022
Ornithonyssus bursa hematophagous mite whose main host is wild and domestic birds, which can temporarily parasitize humans in the absence of the main host. Infestations occur when birds abandon nests or direct contact with infected birds.

Mitochondrial genome evolution and tRNA truncation in Acariformes mites: new evidence from eriophyoid mites

open access: yesScientific Reports, 2016
The subclass Acari (mites and ticks) comprises two super-orders: Acariformes and Parasitiformes. Most species of the Parasitiformes known retained the ancestral pattern of mitochondrial (mt) gene arrangement of arthropods and their mt tRNAs have the ...

Why do Varroa mites prefer nurse bees?

open access: yesScientific Reports, 2016
The Varroa mite, Varroa destructor, is an acarine ecto-parasite on Apis mellifera. It is the worst pest of Apis mellifera, yet its reproductive biology on the host is not well understood.

Population growth of Varroa destructor (Acari: Varroidae) in honey bee colonies is affected by the number of foragers with mites

open access: yesExperimental & applied acarology, 2016
Varroa mites are a serious pest of honey bees and the leading cause of colony losses. Varroa have relatively low reproductive rates, so populations should not increase rapidly, but often they do.

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

open access: yesAdvanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Water mites (Acari, Hydrachnidia): powerful but widely neglected bioindicators – a review

open access: yes, 2016
Various biomonitoring methods are used worldwide to evaluate water quality and the ecological integrity of freshwater habitats. Most of these methods are based upon macroinvertebrates, mainly insects, whereas water mites (Hydrachnidia) are widely ...
