Central European forests experience a substantial loss of open-forest organisms due to forest management and increasing nitrogen deposition. However, strategies, removing different levels nitrogen, have been rarely evaluated simultaneously. We tested the additive effects coppicing topsoil removal on communities dung-inhabiting beetles compared closed forests. sampled 57 021 beetles, using baite...
The origin of the dung-feeding habits in dung beetles (Coleoptera: Scarabaeinae) is debatable. According to traditional views, evolution and their feeding are largely attributed mammal dung. In this paper, we challenge view provide evidence that many beetle communities actually attracted reptiles birds (= Sauropsida). turn, indicates sauropsid may have played a crucial evolutionary role was pre...
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 assessing impacts of logging on forest biodiversity. Here we determine the impact of these roads on the overall condition of selectively logged...
The present review is restricted to the collation and evaluation of information describing the excretion profile and ecotoxicity of veterinary medicines developed specifically for the control of either internal or external parasites of livestock. It identifies numerous gaps in our knowledge and highlights our poor understanding of the environmental fate of many of these chemicals, especially th...
By causing extinctions and altering community structure, anthropogenic disturbances can disrupt processes that maintain ecosystem integrity. However, the relationship between community structure and ecosystem functioning in natural systems is poorly understood. Here we show that habitat loss appeared to disrupt ecosystem functioning by affecting extinction order, species richness and abundance....
Various international bodies and non-governmental organizations (NGOs) have proposed guidelines for safeguarding biodiversity. Nevertheless, quantitative criteria for safeguarding biodiversity should first be established to measure the attainment of biodiversity conservation if biodiversity is to be safeguarded effectively. We conducted research on the impact of logging on biodiversity of dung ...
The introduction of numerous exotic dung beetles across southern Australia in regions where native are not generally efficient processing livestock has resulted significant reductions the quantity such on soil surface recent years. However, direct impacts ecosystem services pasture quality and nutrient mobility have yet been investigated Riverina region New South Wales (NSW), an area recognised...
Tropical forest restoration is becoming increasingly more applied to offset biodiversity loss and maintain ecosystem processes, but knowledge about its efficacy is still limited. We evaluated the success of tropical forest active restoration using dung beetles (Coleoptera: Scarabaeinae) as bioindicators and combining measures of species diversity, composition and functional diversity. We assess...
