Organic Centre Wales Technical Note 5: Biology and management of wireworms [PDF]

open access: yes, 2005
Wireworms are the larvae of a group of beetles commonly known as click beetles. After falling on their backs they right themselves by flicking themselves into the air and produce a “clicking” sound.

Ultrafast Interfacial Engineering for Quantifiable Control of Asymmetric Configurations in Nanostructured Janus Membranes

open access: yesAdvanced Science, EarlyView.
Founded on a rapidly formed nanostructured tannic acid/polyethyleneimine (TA/PEI) platform, an ultrafast (∼5 min), universal interfacial engineering strategy utilizing stearoyl chloride (SC) and Phytic acid (PA) enables precise fabrication of Janus membranes across diverse substrates.

Directed Evolution Improves the Catalytic Efficiency of APEX2‐Mediated Proximity‐Dependent RNA Labeling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

Distribution and biology of the ectoparasitic beaver beetle Platypsyllus castoris Ritsema in North America (Coleoptera: Leiodidae: Platypsyllinae) [PDF]

open access: yes, 2006
The distribution and biology of the beaver beetle, Platypsyllus castoris Ritsema, are summarized for North America. In light of the fact that the beetle uses two beaver species as hosts which have seemingly been separated for some five million years on ...

DNA Nanoarray for Multiplexed RNA Detection With Single‐Molecule Readout

open access: yesAdvanced Science, EarlyView.
A carrier‐based DNA nanoarray integrates programmable nucleic acid hybridization with solid‐state nanopore readout for direct RNA detection at single‐molecule resolution. A ternary encoding system enables 27 carriers with 81 addressable sensing sites, allowing the simultaneous identification of targets spanning a wide size range, from short microRNAs ...

Time since fire strongly and variously influences anthophilous insects in a fire‐prone landscape

open access: yesEcosphere, 2019
Drivers of species productivity and ecosystem function are of great ecological significance. In fire‐prone ecosystems, dispersion patterns of important pollinator species are driven by the various fire events over space and time.

Beetles (Coleoptera)

open access: yes, 2014
The Coleoptera order (beetles) comprises the most species-rich group among the insect class, corresponding to approximately 40% of this class and 30% of all animals, encompassing more than 350,000 described species distributed worldwide (Lawrence 1982; Lawrence and Britton 1994; Arnett and Thomas 2001; Arnett et al. 2002).

Solid Ethanol as a Renewable, Low‐Toxicity, Electron‐Beam Direct Write, and Biomedical Material

open access: yesAdvanced Science, EarlyView.
3D ice lithography (3DIL) enables the fabrication of intricate submicrometer objects using ethanol as a renewable starting material. This study combines process optimization, structural and material analysis, and biomedical applications, from cell culture scaffolds to the patterning of neurostimulation electrodes, demonstrating performance in both in ...

BNB/NBN‐Phenalenyl‐2'‐deoxyuridines as a Fluorophore–Quencher Pair in DNA

open access: yesAngewandte Chemie, EarlyView.
Two BN‐chromophore‐extended nucleosides containing electronically complementary BNB‐ and NBN‐doped phenalenyls were synthesised and incorporated into deoxyribonucleic acid (DNA) oligonucleotides. These chromophores act as an efficient fluorophore–quencher pair under aqueous conditions.

The beetles of St. Lucia, Lesser Antilles (Insecta: Coleoptera): diversity and distributions [PDF]

open access: yes, 2009
The published beetle fauna of the island of St. Lucia is summarized. It contains 135 genera, and 175 species in 25 families. Four species are accidentally introduced by human activities. Twenty three species are endemic (restricted) to the island. Twenty
