To determine the extent to which boreal forest stands support populations of pill beetles, we established a systematic sampling grid of 200 sampling sites covering 82 km2 of boreal mixedwood forest in northwestern Alberta. We found that byrrhid species, especially Simplocaria metallica (Sturm), occur in association with stands of small black spruce (Picea mariana (Mill.) BSP; Pinaceae) subject to frequent disturbances. The habitat occupied by black spruce in this part of the boreal forest also includes potential bryophyte hosts of several pill beetle species. Our findings suggest that pill beetles can be used as indicators of disturbances such as fire, harvest, gravel pit construction, and road ditching. They seem to flourish in frequently disturbed forested habitats such as peat bogs and taiga forest that provide arid environmental conditions similar to arctic or alpine environments.","PeriodicalId":50668,"journal":{"name":"Coleopterists Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135133400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although we report only a single species from Hkamti amber, similarities between these two amber deposits' faunas may be implied by similarities to histerid taxa otherwise described from Kachin amber.

The size of the horns is related to body size and follows either a linear or a distinct, polyphenic relationship. Here, we report the relationship between body size and pronotal horn size in Onthophagus hecate (Panzer, 1794), a common species native to North America. Like other species, the size relationship between pronotal width and pronotal horn was linear. For males, a longer pronotal horn is associated with more furcation and an increase in protuberances: beetles with pronotal horns < 3.65 mm had 2 protuberances, and beetles with horns > 4.27 mm had 4 protuberances. Males also displayed a prominent clypeus, which like their pronotal horn, increased linearly relative to their body size. These allometric relationships provide a baseline for further studies using O. hecate as a model for understanding the genetic and physiological mechanisms of developmental plasticity in insects.","PeriodicalId":50668,"journal":{"name":"Coleopterists Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135133405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As part of their breeding activities, dung beetles remove portions of a dung source and bury them under the soil. This behavior adds nutrients to the soil, aerates the soil, and disperses seeds. Dung beetle species are numerous in forest, prairie, savanna, and pasture ecosystems across the globe, but dung beetle communities vary across elevational gradients and habitat types. A variety of dung beetle species are native to the southeast region of the USA, yet we have limited knowledge of the life history and community assemblage of these species. Previous research on southeastern dung beetles has focused primarily on censusing the species inhabiting agricultural pasture land; bioinventories of dung beetle communities in the Appalachian Mountain regions are thus incomplete. To fill this knowledge gap, a census of dung beetles was performed in the Great Smoky Mountains National Park (North Carolina and Tennessee, USA), quantifying differences in abundance and distribution across season, habitat type, and elevation. Using pitfall traps baited with cattle dung for 24-h periods, dung beetles were collected and identified from six plots once every two weeks during April through September 2017. This research determined that communities of dung beetles varied both temporally and geographically. Low-elevation communities were more diverse than high-elevation communities, and high-elevation communities were dominated by non-native species. Population abundance peaked in late summer at both low and high elevations.","PeriodicalId":50668,"journal":{"name":"Coleopterists Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135133414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
