DOI: 10.1007/s00049-020-00319-z
Abstract: Females of two click beetle species, Cardiophorus tenebrosus and C. edwardsi (Coleoptera: Elateridae), produce methyl (3R,6E)-2,3-dihydrofarnesoate as their sex pheromone. We had serendipitously discovered that males of both species were also strongly attracted to (R)-fuscumol… read more here.

DOI: 10.1007/s00442-020-04716-7
Abstract: A 23-year time-series of abundance for 13 lady beetle species (Coccinellidae) was used to investigate community stability. The community exhibited persistence in ten habitats, no overall trend in abundance, and low temporal variability quantified as… read more here.

DOI: 10.1093/ee/nvac067
Abstract: Abstract In western North America, sympatric Limonius click beetle species produce limoniic acid [(E)-4-ethyloct-4-enoic acid] as a sex pheromone component (L. canus (LeConte), L. californicus (Mannerheim)) or respond to it as a sex attractant (L.… read more here.

DOI: 10.1111/jbi.14043
Abstract: Nearly 40 different hypotheses have been put forward to explain the latitudinal diversity gradient, implying that geographical variations of biodiversity may be the result of a complex array of factors affecting organisms in different ways.… read more here.

DOI: 10.1166/mex.2020.1817
Abstract: The role of floral visual cues was studied in both sexes of three nocturnal scarab beetle species (Holotrichia oblita, Holotrichia parallela, and Anomala corpulenta). Flower patterns were designed using n-petal rose curve and radial gradient… read more here.

DOI: 10.1371/journal.pone.0178077
Abstract: Cattle farming is a major source of greenhouse gases (GHGs). Recent research suggests that GHG fluxes from dung pats could be affected by biotic interactions involving dung beetles. Whether and how these effects vary among… read more here.

DOI: 10.3390/insects13080668
Abstract: Simple Summary The taxonomy of many African Coleoptera species is remains poorly known, and the knowledge of their ecological requirements is worse still. Starting with original data, we describe morphological differences and ecological data for… read more here.

DOI: 10.7717/peerj.9872
Abstract: Dung beetle introduction programmes were designed to accelerate exotic livestock dung degradation and to control dung breeding pestiferous flies and livestock parasites. The introduction programmes provided exotic dung beetle species with an opportunity to cross… read more here.
