Cladistic biogeography of the Mexican transition zone
Biogeographic relationships among nine montane areas of endemism across the transition zone between North and South America are analysed cladistically based on phylogenetic hypotheses of thirty‐three
Wood ingestion by passalid beetles in the presence of xylose‐fermenting gut yeasts
TLDR
The consistent association of xylose‐fermenting yeasts of almost identical genotypes with passalid beetles across a broad geographical distribution, suggests a significant symbiotic association.

Palaeocene high-latitude coals from the Todalen Mbr. Central Tertiary Basin, Svalbard present an opportunity to understand the processes which controlled Arctic peat formation. Coals from this region
Foraging westward for pristine nonmare rocks - Complications for petrogenetic models
New advances are reported concerning an investigation which is being conducted to find and characterize more 'pristine' (compositionally endogenous) lunar rocks. Eleven nonmare samples are
Aggregated occurrence records of the federally endangered Poweshiek skipperling (Oarisma poweshiek)
TLDR
This dataset enhances the permanency of Poweshiek skipperling occurrence data in a standardised format and aggregates presence data from state conservation agencies, natural heritage programmes, natural history collections, citizen scientists, researchers and the U.S. Fish & Wildlife Service.
One Hundred Million Years of Chemical Warfare by Insects
TLDR
The discovery of an Early Cretaceous soldier beetle in Burmese amber that seemingly employed a chemical defense response against a potential predator suggests that chemical defense mechanisms in beetles have been in existence for at least 100 Ma.
(R)-Desmolactone Is a Sex Pheromone or Sex Attractant for the Endangered Valley Elderberry Longhorn Beetle Desmocerus californicus dimorphus and Several Congeners (Cerambycidae: Lepturinae)
TLDR
The results represent the first example of a “generic” sex pheromone used by multiple species in the subfamily Lepturinae, and demonstrate that phersomone-baited traps may be a sensitive and efficient method of monitoring the threatened species Desmocerus californicus dimorphus, commonly known as the valley elderberry longhorn beetle.
