“…In addition, by making tunnels, dung beetles also help to reduce soil compaction and increase soil aeration, facilitating nitrogen mineralization (Manning et al, 2016;Xu et al, 2020;Stanbrook et al, 2021). An increase in the all the nutrients was observed in Group II in all the 4 soil types; however, N levels were found to be highest in sandy clay loam and loamy sand soilconfirming the affirmative role of the dung beetles in nutrient cycling (Zhao et al, 2008;Kronzucker, et al, 2013;Menéndez et al, 2016;Badenhorst et al, 2018;Kandil, 2019;Salomão et al, 2022). Thus, O. taurus appears to have an important role in nutrient cycling, and their relative importance also depends on the soil type.…”

Dung beetles play a major role in the pasture ecosystem. The manure recycling activity of dung beetles is linked to their tunneling behavior. The present study was designed to analyze the tunnel pattern and nutrient mobilization by dung beetles, Onthophagus taurus (Schereber, 1759) in different soil types. A simple type of tunnel pattern was observed in all the four types of soil after 30th day of their introduction (10 pairs of male and female) into the experimental setup. However, the maximum number of tunnels was observed in the sandy and sandy clay loam (no. of openings - 15), followed by loamy soil (no. of openings -13). The physical (texture, water holding capacity, porosity, moisture content) and chemical parameters (pH and nutrients) of all the four types of soils were evaluated. Soil texture analysis revealed the texture to be of sandy (yellow soil), sandy clay loam (red and black soil), and loamy sand (brown soil) types. Water holding capacity and the soil porosity were recorded highest in the sandy soil, whereas moisture content was found maximum in the sandy clay loam. Soil nutrient analysis illustrated a significant increase in the amount of nitrogen (N), phosphorus (P), calcium (Ca), sulfur (S), sodium (Na), potassium (K), organic carbon and organic matter. Thus, the present study confirms that tunneling activity of O. taurus enhances the soil nutrients by carrying out dung decomposition.

“…proportions of silt, clay and sand) may also sustain species with specific habitat requirements due to differences in microhabitat conditions (Davis et al 2016;Daniel et al 2022). For instance, Salomão et al (2022) found that species richness of endocoprids increased with silt contents in central Amazon rainforest, while clay content was important for abundance and changes in composition of the entire community and species richness of paracoprid species. In addition, Silva et al (2015) found that small paracoprids and telecoprids are most affected by variation of the soil granulometry in a semideciduous forest in central South America.…”

“…Most dung beetle species build their nests in the soil or at the dung-soil interface (Halffter & Edmonds 1982). Therefore, soil type and conditions are important determinants of dung beetle spatial distribution (Doube 1983;Davis 1996;Silva et al 2015;Farias and Hern andez 2017;Salomão et al 2022). Soil compaction may represent a challenge for the construction of tunnels by dung beetles (Dabrowski et al 2019).…”

Environmental drivers of taxonomic and functional diversity of dung beetles across a chronosequence of tropical grasslands with different cattle grazing removal ages

Livestock is a globally widespread farming practice, with benefits and harms for biodiversity. Biodiversity responses to vegetation and soil conditions associated with cattle grazing removal are poorly understood in tropical grassy ecosystems, especially in a long-term chronosequence. In this study, we aimed to identify the main drivers of local conditions on dung beetle taxonomic and functional diversity across a chronosequence of natural grasslands with different cattle grazing removal ages. We expect that vegetation and soil variables associated with environmental changes caused by longer time after cattle grazing removal will drive the taxonomic and functional diversity of dung beetles. We sampled dung beetles and recorded local environmental filters (vegetation and soil variables) in 14 natural grasslands with distinct cattle grazing removal ages (from 3 months to 22 years) and also in 10 reference sites (with cattle grazing). We used structural equation models to evaluate the relationships between the most informative explanations (vegetation and soil variables) of dung beetle taxonomic and functional metrics. Our results provide evidences that local conditions related to vegetation and soil variables in natural grasslands affect the taxonomic and functional diversity of dung beetles differently. Soil conditions (compaction and silt content) had more influence, mostly negative, on taxonomic metrics, while vegetation complexity had more influence on functional metrics, with positive or negative effects depending on the functional metric evaluated. Understanding the temporal change in vegetation and soil conditions can shed light on the process of recovering biodiversity and ecosystem functions in areas with different times of abandonment of livestock farming. Finally, using taxonomic and functional approaches together can also help to better understand how organisms are responding to the process of abandoning livestock farming over time.
