Sensitivity and tolerance of Riparian arthropod communities to altered water resources along a drying river. [PDF]

open access: yesPLoS One, 2014
Rivers around the world are drying with increasing frequency, but little is known about effects on terrestrial animal communities. Previous research along the San Pedro River in southeastern AZ, USA, suggests that changes in the availability of water ...

Chemical Defense of an Ozaenine Bombardier Beetle From New Guinea [PDF]

open access: yesPsyche: A Journal of Entomology, Volume 96, Issue 3-4, Page 153-160, 1989., 1989
We had occasion recently to study 3 live specimens of Pseudozaena orientalis opaca, an ozaenine carabid beetle (subfamily Paussinae, tribe Ozaenini) from New Guinea, and report here on the biology and chemistry of its defensive spray mechanism.

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

open access: yesEcol 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.

Bombardier beetles repel invasive bullfrogs

open access: yesPeerJ
Invasive non-native predators negatively affect native species; however, some native species can survive the predation pressures of invasive species by using pre-existing antipredator strategies or evolving defenses against invasive predators. The American bullfrog Lithobates catesbeianus (Anura: Ranidae) has been intentionally introduced to many ...

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

open access: yesInsect 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]

open access: yesEcol 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]

open access: yesBiochem 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

open access: yesAdvanced 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

open access: yesActa 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 ...
