Effects of Predator Species and Size on Prey Escape Success Through the Digestive Tract. [PDF]

Ecol Evol
Adults of the aquatic beetle Regimbartia attenuata can survive passage through the digestive tracts of six predator (frog) species, including a non‐native bullfrog. Their active movement through the gut likely facilitates their escape through the cloaca, irrespective of predator species or size.

The molecular mechanisms of defensive-grade organic acid biosynthesis in ground beetles. [PDF]

Insect Mol Biol
Formic acid and methacrylic acid are the primary defensive chemicals in the pygidial gland secretions of Platynus angustatus and Pterostichus moestus, respectively. Comparative transcriptomics suggests the folate cycle and valine catabolism may be involved in the biosynthesis of formic acid and methacrylic acid, respectively.

Comparative and Phylogenetic Analyses of Mitochondrial Genomes in Carabidae (Coleoptera: Adephaga). [PDF]

Ecol Evol
In this study, six complete mitochondrial genomes (mitogenomes) from the genus Harpalus are reported. Additionally, 13 cases of suspected misidentifications in public Carabidae mitogenomes from GenBank were identified, with potential corrections suggested.

A Comprehensive Exploration of Bioluminescence Systems, Mechanisms, and Advanced Assays for Versatile Applications. [PDF]

Biochem Res Int
Bioluminescence has been a fascinating natural phenomenon of light emission from living creatures. It happens when the enzyme luciferase facilitates the oxidation of luciferin, resulting in the creation of an excited‐state species that emits light. Although there are many bioluminescent systems, few have been identified.

Accurate Magneto‐Driven Multi‐Dimensional Droplet Manipulation

Advanced Functional Materials, Volume 33, Issue 9, February 23, 2023., 2023
Based on the in‐deep research on the mechanism of horizontal transport and vertical droplet capture/release, the noncontact magnetic micropillars array is designed to achieve 3D droplet controllable manipulation for transportation of long‐distance, across‐obstacle, and other severe working conditions.

Differences between poison and venom: An attempt at an integrative biological approach

Acta Zoologica, Volume 102, Issue 4, Page 337-350, October 2021., 2021
Abstract We discuss the use of the terms venom and poison, in the context of integrative biology, with particular emphasis on behaviour and natural history. Our purpose is to reach a broad scientific audience, especially that dedicated to zoology. The meaning of the two terms is reviewed from the secretory perspective, mainly focussed on the reptiles ...

X‐ray microtomography and phylogenomics provide insights into the morphology and evolution of an enigmatic Mesozoic insect larva

Systematic Entomology, Volume 46, Issue 3, Page 672-684, July 2021., 2021
A new, morphologically unique lacewing larva from Cretaceous amber of Myanmar (Kachin state) is described and rendered using X‐ray phase‐contrast microtomography. The phylogenetic analysis integrating morphological and genomic data from extant and extinct taxa recovers this larva near antlions, corroborating the Cretaceous as an evolutionary ...

A biomimetic study of the explosive discharge of the bombardier beetle [PDF]

International Journal of Design & Nature, 2007
A biomimetic study of the bombardier beetle’s explosive discharge apparatus was undertaken using numerical (CFD) modelling, first, of the beetle’s combustion chamber, and then of a scaled-up combustion chamber with a view to its application to devices such as gas turbine relighters.

Molecular Phylogeny and Revision of Species Groups of Nearctic Bombardier Beetles (Carabidae: Brachininae: Brachinus)

, 2021
Bombardier beetles of the genus Brachinus Weber are notorious for their explosive defensive chemistry; when threatened, they aim a 100°C cloud of benzoquinones directly at an enemy.
