Metagenomics reveals that dung beetles (Coleoptera: Scarabaeinae) broadly feed on reptile dung. Did they also feed on that of dinosaurs?

open access: yesFrontiers in Ecology and Evolution, 2023
The origin of the dung-feeding habits in dung beetles (Coleoptera: Scarabaeinae) is debatable. According to traditional views, the evolution of dung beetles (Coleoptera: Scarabaeinae) and their feeding habits are largely attributed to mammal dung.

Forest habitat parameters influence abundance and diversity of cadaver-visiting dung beetles in Central Europe [PDF]

open access: yesRoyal Society Open Science, 2020
Dung beetles provide crucial ecosystem services and serve as model organisms for various behavioural, ecological and evolutionary studies. However, dung beetles have received little attention as consumers of large cadavers.

Nutrient quality of vertebrate dung as a diet for dung beetles [PDF]

open access: yesScientific Reports, 2017
AbstractAt the basis of a trophic web, coprophagous animals like dung beetles (Scarabaeoidea) utilize resources that may have advantages (easy gain and handling) as well as drawbacks (formerly processed food). Several studies have characterized the nutrients, e.g. C/N ratios and organic matter content, for specific types of dung. However, a comparative

Quantifying immediate and delayed effects of anthelmintic exposure on ecosystem functioning supported by a common dung beetle species. [PDF]

open access: yesPLoS ONE, 2017
Dung beetles (Coleoptera: Scarabaeoidea) support numerous ecosystem functions in livestock-grazed pastures. Exposure to veterinary anthelmintic residues in livestock dung can have lethal and sublethal effects on dung beetles, and can reduce rates of dung

Prevalence of the dog nematode Spirocerca lupi in populations of its intermediate dung beetle host in the Tshwane (Pretoria) Metropole, South Africa

open access: yesOnderstepoort Journal of Veterinary Research, 2008
Spirocerca lupi (Spirurida: Spirocercidae) is a cosmopolitan parasite, principally of domestic dogs and dung beetles are its main intermediate hosts.

A ‘metaphising’ dung beetle [PDF]

open access: yesThe EMBO Reports, 2010
Humans and beetles both have a species-specific Umwelt circumscribed by their sensory equipment. However, Ladislav Kovac argues that humans, unlike beetles, have invented scientific instruments that are able to reach beyond the conceptual borders of our Umwelt.

The role of dung beetles in seed dispersal in an arid environment

open access: yesEcología Austral, 2023
Dung beetles can influence seedling emergence and survival. However, the direction and magnitude of this effect will depend on the functional traits of the dung beetle community and on the prevailing environmental conditions. We studied the role of dung

Quantifying beetle-mediated effects on gas fluxes from dung pats. [PDF]

open access: yesPLoS ONE, 2013
Agriculture is one of the largest contributors of the anthropogenic greenhouse gases (GHGs) responsible for global warming. Measurements of gas fluxes from dung pats suggest that dung is a source of GHGs, but whether these emissions are modified by ...

The Effect of Dung Beetle Size on Soil Nutrient Mobilization in an Afrotropical Forest

open access: yesInsects, 2021
Despite recognition of its importance, little is known about functional aspects of soil macrofauna. Here, we investigated the effect of dung beetle body size on macronutrient movement (N, P, K, and C) from elephant dung into soil over 112 days in an ...
