Modelling habitat and spatial distribution of an endangered longhorn beetle - A case study for saproxylic insect conservation
An Endangered Longhorn Beetle Associated with Old Oaks and Its Possible Role as an Ecosystem Engineer
The results suggest that an endangered beetle species can alter its own habitat to create favorable habitat conditions for other threatened beetle species, and that reintroductions might be considered in regions where the species has become extinct.
Designing forest biodiversity experiments: general considerations illustrated by a new large experiment in subtropical China
It is concluded that forest BEF experiments provide exciting and timely research options and especially require careful thinking to allow multiple disciplines to measure and analyse data jointly and effectively.
Tree diversity promotes insect herbivory in subtropical forests of south-east China
The positive herbivory–plant diversity relationship indicates that effects related to hypotheses of resource concentration, according to which a reduction in damage by specialized herbivores might be expected as host plant concentration decreases with increasing plant diversity, do not seem to be major determinants for overall Herbivory levels in the authors' phytodiverse subtropical forest ecosystem.

Levels of genetic variation within a geographically isolated relict population (Martha's Vineyard, MA) as well as within an undisturbed population (Chesapeake Bay, MD), were very low, indicating that even historically these beetles were genetically depauperate.
Predator Diversity and Abundance Provide Little Support for the Enemies Hypothesis in Forests of High Tree Diversity
The results provide little support for the enemies hypothesis—derived from studies in less diverse ecosystems—of a positive relationship between predator and plant diversity, and question whether stronger top-down control of food webs can be expected in the more plant diverse stands of the forest ecosystem.
The ground beetle fauna of ancient and recent woodlands in the lowlands of north-west Germany (Coleoptera, Carabidae)

Half of the eight brachypterous woodland species is exclusively or predominantly found in ancient woodlands, suggesting that power of dispersal is an important factor which determines the species number in woodland fragments of different age.
Can management compensate for atmospheric nutrient deposition in heathland ecosystems
This study shows that low- intensity management cannot compensate for atmospheric N loads in the long term, and high-intensity management measures are an indispensable tool in preserving a long-term balanced N budget in heathlands.
Impacts of species richness on productivity in a large-scale subtropical forest experiment
The first results from a large biodiversity experiment in a subtropical forest in China suggest strong positive effects of tree diversity on forest productivity and carbon accumulation, and encourage multispecies afforestation strategies to restore biodiversity and mitigate climate change.
Carabids.org – a dynamic online database of ground beetle species traits (Coleoptera, Carabidae)
The project contributes to the rapid expansion and analysis of freely available traits data on species‐rich invertebrates, which will help to advance the understanding of community assembly and functional diversity effects of such taxa across large spatial scales.
