Using Metabarcoding Techniques to Map Multiple Dung Beetle‐Vertebrate iDNA Networks in a Southeast Asian Forest

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Given the high levels of endemism, diversity, and increasing anthropogenic impacts in tropical regions, studies on species interactions and ecological networks are urgently needed to understand community responses to environmental change. Increasingly, molecular methods are used to monitor biodiversity and identify species interactions.

Who prefers the dark? Daily activity of dung beetles from an Amazonian region

Ecological Entomology, Volume 51, Issue 3, Page 609-613, June 2026.
Daily activity patterns shape how dung beetle species coexist in Amazonian forests, revealing temporal niches that reduce competition and structure biodiversity. We compared species richness, abundance and assemblage composition of dung beetles sampled during day and night in a conserved terra‐firme forest in the Brazilian Amazon. Although richness and

Dung beetles as bioindicators of environmental change from artisanal small-scale gold mining

Environmental Research: Ecology
The expansion of gold mining across Amazonia is a major driver of deforestation, yet its impacts on biodiversity are understudied. Dung beetles (Scarabaeinae) are excellent bioindicators and have been shown to be highly sensitive to habitat modification,

Chromosomal organization of the 18S and 5S rRNAs and histone H3 genes in Scarabaeinae coleopterans: insights into the evolutionary dynamics of multigene families and heterochromatin

BMC Genetics, 2011
Background Scarabaeinae beetles show a high level of macro-chromosomal variability, although the karyotypic organization of heterochromatin and multigene families (rDNAs and histone genes) is poorly understood in this group.

Diversity of Scarabaeinae (Coleoptera: Scarabaeidae) in an urban fragment of Cerrado in Central Brazil

European Journal of Entomology, 2020
The diversity of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) is affected by urbanization, habitat fragmentation and disappearance of native mammals, which result in changes in the quality and availability of food, and resources for nesting.

Effects of soil physical properties on dung beetle assemblages in pasture landscapes of the Brazilian Cerrado

Agricultural and Forest Entomology, Volume 28, Issue 2, Page 169-181, May 2026.
We assessed the effect of the type of soil texture (loamy sand and sandy loam) and its physical properties on dung beetle species assemblages in a pastureland region of the Brazilian Cerrado. We found a reduction in the total and paracoprid beetle abundances in loamy sand soil. Furthermore, the increase of soil compaction negatively affected the entire

Towards red listing understudied tropical insects: A case study of the dung beetles of Sabah, Malaysian Borneo

Insect Conservation and Diversity, Volume 19, Issue 3, Page 511-529, May 2026.
We performed an IUCN Red List assessment for 159 dung beetle species from Sabah, Malaysian Borneo. Due to the lack of population demographic data, only Criterion B (i.e. geographic range) could be applied. Our findings show that the IUCN Red List Criteria can be applied to insect species based solely on occurrence data but highlight the importance of ...
