Description of a new species of Chrysina Kirby, 1828 (Coleoptera: Scarabaeidae: Rutelinae) from optima group, based on morphological characters and mtDNA COX I molecular marker

open access: yesActa Biologica Sibirica, 2019
A new species of the genus Chrysina Kirby, 1828 is decribed from Panama. Chrysina valentini sp.n. is related to Chrysina tricolor (Ohaus, 1922) and Chrysina optima (H. W. Bates, 1888) in morphology and mtDNA COX I molecular marker.

Parental Social Environment Has no Effect on Offspring Development in the Dung Beetle: A Test of Adult Sex Ratio Effects

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We investigated whether adult sex ratio (ASR) induces transgenerational plasticity in the dung beetle Onthophagus taurus via germline transmission or behavioral parental investment. Although varying ASR treatments significantly altered parental contest and courtship behaviors, utilizing a novel egg‐transplantation protocol revealed no ASR‐induced ...

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

open access: yesJournal of Animal Ecology, Volume 95, Issue 7, Page 1207-1219, July 2026.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Phylogenetic Authentication of Amplicon Sequence Variants in Single‐Specimen Metabarcoding of Tropical Insects

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT High‐throughput sequencing (HTS) allows large‐scale DNA barcoding of individually tagged specimens (‘megabarcoding’), but deep amplicon sequencing produces a mixture of authentic mitochondrial sequences together with nuclear pseudogenes (NUMTs), environmental and cross‐sample contaminants, and sequencing artefacts.
