By identifying the factors limiting the scope for dung beetle mitigation of GHG emissions in this highly-industrialized production system, we then point to other, still poorly-explored production systems in both temperate and tropical regions, where dung beetles are particularly likely to have an ...
After landing at a fresh dung pile, a beetle quickly forms a dung ball and rolls it away in a straight line, head down, walking backwards [2]. Earlier studies have shown that some dung beetles maintain an elevated body temperature to gain a competitive advantage 3, 4, 5, and that heat...
Insect defensin, coprisin is a 43-residue antimicrobial peptide isolated from the dung beetle. Coprisin shows antibacterial and anti-inflammatory activity with bacterial cell selectivity. An amphipathic helix and electropositive surface may play important role in its antimicrobial activity. We provided th...
Richness of dung beetle assemblages in native forest and livestock systems in subtropical forests of Argentina. Circles: Native forest; triangles: Silvopastoral systems; squares: Open Pastures. Different letters indicate significant differences (P < 0.05). Full size image The first axis of the three ...
With all the animals moving around the forest, your average dung (粪)beetle shouldn't behunting for food. There is dung enough for everyone, isn't there?Now in the lowland rainforests of Peru, competition for food has obviously led to theevolution of a dung beetle that eats no dung at ...
So far he had spent the first three days of his tenure doing little more than conducting job interviews with beetle-browed economists far to the right of the late Milton Friedman while nursing his attendant migraine, and sneaking a nostalgic look at the Hang Seng Index on Bloomberg TV. His ...

On an annual scale, taking into account the non-grazing period, the dung beetle effect on the pasture CH4 fluxes was 21% (Fig. 2b). Dung beetles slightly reduced the N2O fluxes from the pasture-by 5% during the grazing season and by 0.1% over the course of the year (Supplementary ...
One of the limitations of the dung beetle optimization (DBO) is its susceptibility to local optima and its relatively low search accuracy. Several strategies have been utilized to improve the diversity, search precision, and outcomes of the DBO. However, the equilibrium between exploration and explo...
The process of the MSIDBO algorithm is shown in Figure 3. Figure 3. Process of MSIDBO algorithm. 3.2.1. Fuch Chaotic Mapping and Opposition-Based Learning Strategy Fusion The quality of the initial dung beetle population will have a huge impact on the calculation results of the model, and...
