Dung beetle diversity was lower in pastures than in forests. However, the total biomass of beetles at similarly-sized dung baits was frequently higher in pastures. Diversity loss followed structured patterns: (1) carrion and fruit feeding beetles were well represented (species number) in the forests but were largely absent from pastures; (2) large ball rollers and small fast tunnellers were present in forests but were absent from pastures; (3) large fast tunnellers and small slow tunnellers were poorly represented in pastures com- pared to forests but the few species that survived in pastures attained extremely high popu- lations; and (4) each functional group in the species-poor pasture assemblages was divided almost equally into day and night active species. Substrate and habitat generalists that were present in both the forests and pastures were attracted to fruit and carrion in forested habitat but not in open pastures. In open habitats, Xies and other insects may be the principal decomposers of decaying fruit and carrion. 10acarrion10adecomposition10adeforestation10aDiversity-function10afunctional groups10aguilds10aScarabaeidae10atropical pastures1 aHorgan, Finbarr, G  uhttps://scarabnet.myspecies.info/dung-beetle-assemblages-forests-and-pastures-el-salvador-functional-comparison01372nas a2200217   4500008004100000245012400041210006900165300001200234490000800246520061900254653002500873653001200898653001700910653000900927653001400936653001300950653001700963653001500980100002100995856013801016       2006                        eng d00aLaboratory studies on the feeding behavior of the putative dung beetle, Ateuchus histeroides (Coleoptera: Scarabaeidae)0 aLaboratory studies on the feeding behavior of the putative dung   a157-1690 v1143 aAbstract.—Through a series of laboratory feeding trials, it was demonstrated that the putative dung beetle, Ateuchus histeroides Weber (Coleoptera: Scarabaeidae), is a consumer of both vertebrate dung and insect carrion, and that it can produce progeny reared on either of those foods. There was no significant difference between the survival periods of adults maintained on either cow dung or dead insects, but both groups survived significantly longer than a group deprived of food. This is the first documentation of both dung and carrion feeding and subsequent progeny production for a member of this genus. 10aAteuchus histeroides10acarrion10adead insects10aDung10alongevity10aprogeny.10aScarabaeidae10astarvation1 aYoung, Orrey, P.  uhttps://scarabnet.myspecies.info/laboratory-studies-feeding-behavior-putative-dung-beetle-ateuchus-histeroides-coleoptera-scarabaeida
