“…The high abundance of beetles in the protection and rehabilitation zones may related to the presence of mammals and the complexity of plant species. Similarly, Simba et al (2022) reported the abundance and species richness of beetles was higher in protected area compared to agricultural area. The abundance of beetles also increases along the number of mammals in the area.…”

Scarabaeid beetles have an essential role in forest ecosystems, such as nutrient recycling, seed dispersal, forest regeneration, controlling parasite, and reducing carbon emissions. Until now, there has been no publication on scarabaeid beetle diversity in the lowland rainforest ecosystem of Papua, Indonesia. This study aims to measure the diversity of scarabaeid beetles in the lowland rainforest ecosystem of Sorong Nature Tourisme Park (SNTP), West Papua, Indonesia. Determination of study sites used in this study was using the purposive sampling method in three habitat types i.e., rehabilitation zone, conservation zone, and protection zone using baited dung traps (type A, B, and C dung traps), light trap, and active sampling. The fresh cow and human feces baits were used for dung traps that was replaced every 24 hours (68 repetitions for 68 days) in each habitat. Results showed a total of 30 individuals belonging to 13 species of scarabaeid beetles were collected. Onthophagus has the highest species richness (5 species) and the low species richness were Aphodius sp., Anomala sp., and Adoretus sp. (1 species). The protection zone has the highest diversity index (H’=2.09), followed by the conservation zone (H’=2), and rehabilitation zone (H’=0.5). Based on trap type, dung trap collected the most beetle species (9 species), followed by light trap (6 species), and active sampling (2 species). Based on Pearson correlation, soil pH significantly correlated with beetle abundance. This study was the first report of scarabaeid beetles in the West Papua, Indonesia.

“…Climatic conditions play a significant role in driving the spatiotemporal distribution of dung beetles (Correa, da Silva, et al, 2021; Ferreira et al, 2019; Noriega, Santos, et al, 2021). Changes in temperature and precipitation regimes across regions and seasonally cause major variations in dung beetle assemblage metrics (Batista et al, 2016; da Silva et al, 2013; Simba et al, 2022). However, the effects of these variables on the dung beetle assemblage may be greater or lesser depending on the spatial and temporal scale under study.…”

Understanding the processes and mechanisms that underlie the spatiotemporal patterns of biodiversity is of paramount relevance, given the ongoing global climate and land cover changes. Here, we investigated the influence of season‐related climatic variables on two dimensions of dung beetle diversity (taxonomic and functional) and at different scales (alpha and beta) within an introduced Brazilian pasture ecosystem. We sampled dung beetles over 52 consecutive weeks, comprising the dry and rainy seasons. We related taxonomic and functional variables to season‐related climate variables (temperature, precipitation and humidity) using absolute values and changes from consecutive samplings (Δ, differences between samplings). We found higher species richness and abundance values in the rainy season. Changes in climatic variables between consecutive samplings caused effects only in functional dispersion, temporal β‐diversity and species losses but not in species richness and abundance of dung beetles. However, these effects are dependent on the season. In the rainy season, increased precipitation between samplings caused a decrease in functional dispersion and an opposite pattern was found in the dry season. Similarly, increased temperature values between samplings caused decreases in both temporal β‐diversity and species losses of dung beetles, with an opposite pattern in the dry season. Season‐associated climatic variables showed contrasting effects on dung beetle taxonomic and functional metrics. Temporal changes in taxonomic and functional diversity may be driven by different climatic variables, which can be associated with the sorting of species or species traits related to their thermal niche.

“…This taxon has been extensively studied in its response to human disturbance due to its sensitivity, abundance, distribution and well‐known taxonomy (Nichols et al, 2007; Nichols & Gardner, 2011; Spector, 2006). In addition, dung beetle diversity and abundance respond to large‐scale environmental gradients, mainly to variations in precipitation (Abdel‐Dayem et al, 2016; Hortal‐Muñoz et al, 2000; Nunes et al, 2016; Simba et al, 2022). Also, Maldaner et al (2021) showed that climate changes in temperature and precipitation conditions influence the distribution of dung beetle species.…”

Climate as a determinant of dung beetle response to native forest replacement by cattle pastures in South America

Anthropogenic disturbance in natural ecosystems reduces the number of species in biological communities and homogenizes their composition across different regions. Climate is one of the main abiotic determinants of species distributions and different factors were proposed as the main climatic drivers. Here we explored the role of regional climate on the local response of dung beetle assemblages to the replacement of native forest by cattle pastures in South America by simultaneously contrasting three climatic hypotheses: energy, seasonality and heterogeneity. We compiled a database by searching published studies comparing dung beetle richness and composition between both native forests and cattle pastures. We calculated the proportional difference in species richness and composition between habitat types. As explanatory variables, we used seven abiotic variables grouped into the three climatic hypotheses. Energy/Productivity: mean annual temperature (°C/year) and total annual precipitation (mm/year). Seasonality: annual thermal amplitude (°C/year), the average coefficient of variation of monthly precipitation and the coefficient of average monthly variation in temperature. Heterogeneity: coefficient of variation of mean annual temperature, coefficient of variation of mean annual precipitation. Using regression analyses and a model selection procedure, we found differences in species richness between native forests and cattle pastures were explained by the coefficient of variation of mean annual precipitation, whereas changes in species composition were explained by total annual precipitation and the coefficient of variation of mean annual precipitation. The response of dung beetle assemblages to livestock grazing in South American forests was associated with precipitation variation. The heterogeneity hypothesis better explained changes in species richness following forest replacement by cattle pastures, while both energy/productivity and heterogeneity hypotheses explained the changes in species composition.
