Resource shifts in Malagasy dung beetles : contrasting processes revealed by dissimilar spatial genetic patterns [PDF]

, 2008
The endemic dung beetle subtribe Helictopleurina has 65 species mostly in wet forests in eastern Madagascar. There are no extant native ungulates in Madagascar, but three Helictopleurus species have shifted to the introduced cattle dung in open habitats ...

The impact of logging roads on dung beetle assemblages in a tropical rainforest reserve [PDF]

, 2017
The demand for timber products is facilitating the degradation and opening up of large areas of intact habitats rich in biodiversity. Logging creates an extensive network of access roads within the forest, yet these are commonly ignored or excluded when ...

Economic value of dung removal by dung beetles in US sub-tropical pastures

Basic and Applied Ecology
In livestock management systems, the rapid removal of cattle dung by dung beetles plays an essential role in returning areas of pasture to grazing which normally would be lost because of dung contamination. Thus, dung removal is an ecosystem process with

Improved Dung Beetle Optimizer Algorithm With Multi-Strategy for Global Optimization and UAV 3D Path Planning

IEEE Access
In high-dimensional scenarios, path planning is a challenging and computationally complex optimization task that requires finding optimal paths within complex domains. Metaheuristic (MH) algorithms offer a practical approach to addressing this issue. The

Success or failure: the role of ecological restoration on the recovery of dung beetle diversity and function in a tropical rainforest

Revista Mexicana de Biodiversidad, 2018
Recent studies have shown that ecological restoration hardly recovers diversity and ecosystem function of important bioindicator groups such as dung beetles, which have key functional roles in natural and managed ecosystems.
