Nature's Chemical Weapons: Beetle Defenses

open access: yesCHIMIA, 2019
The defense chemicals secreted by beetles are very diverse. They are exemplified by those of members of the families Carabidae (ground beetles) and Coccinellidae (ladybirds).

Ground Beetles (Coleoptera: Carabidae) Inhabiting Stands of Reed Canary Grass Phalaris Arundinacea on Islands in the Lower Chippewa River, Wisconsin [PDF]

open access: yes, 2018
We used pitfall traps to assess ground beetle diversity (Coleoptera:Carabidae) on two islands in the lower Chippewa River, Eau Claire County, Wisconsin, with rapidly expanding populations of reed canary grass, Phalaris arundinaceae.

Triplet‐Triplet Annihilation Enhances Photochemical Curing Contrast for Vat‐Based 3D Printing

open access: yesAdvanced Functional Materials, EarlyView.
Triplet–triplet annihilation photopolymerization (TTAP) resins enhance curing contrast for digital light processing (DLP) 3D printing compared to conventional Type I and II photopolymerizations at matched optical densities. By exploiting a superlinear initiation response, TTAP preserves fine details, allowing reliable fabrication of complex structures ...

Do covers influence the capture efficiency of pitfall traps?

open access: yesEuropean Journal of Entomology, 2009
Pitfall traps are widely used in terrestrial ecology to capture ground-dwelling arthropods. In order to determine the effect of covers placed over pitfall traps on their efficiency at capturing of spiders, carabid beetles and ants, four types of pitfall ...

Movement Patterns of Carabid Beetles Between Heterogenous Crop and Noncrop Habitats [PDF]

open access: yes, 2018
Habitats adjacent to crop fields can increase natural enemy populations by providing additional food, shelter and overwintering sites. While many studies have focused on the role of non-crop borders for supporting natural enemies, here we investigate the

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

open access: yesAdvanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Ground Beetles From a Remnant Oak-Maple-Beech Forest and Its Surroundings in Northeastern Ohio (Coleoptera: Carabidae) [PDF]

open access: yes, 2017
We report 66 ground beetle species in 14 tribes from a natural preserve in northeastern Ohio (Stark County). Six species are new state records. Data from pitfall trap transects across adjoining habitats suggest narrow habitat preferences in some species ...

Life forms of endemic carabid beetles (Coleoptera, Carabidae) in the forest eco-systems of gorgany mountains

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2010
In the forest ecosystems of Gorgany Mountains 11 endemic carabids are found. It is about 12.2 % of all ground-beetles fauna of the investigated region. As a result of the morphometric analysis the life forms of endemic carabids are determined. The system
