High diversity in host community can increase (amplification effect) or reduce (dilution effect) the transmission of pathogens, due to context-dependent differences in life history traits between hosts. Trace metals (TMs) circulate from resources to consumers via trophic links. Given the variety of life history traits within resources, it is hypothesized that their diversity would play functional roles on the transfer of TMs to consumers. The aim of this work was to test this hypothesis and to determine the underlying mechanisms, using the wood mouse (Apodemus sylvaticus) as a model consumer. Sampling was undertaken around the former smelter Metaleurop Nord in Northern France where soils were contaminated by cadmium (Cd), lead (Pb) and zinc (Zn). Analyses about mice resources’ distribution in the field (plants and invertebrates) showed that diversity was not, or slightly positively, correlated with soil TM contamination levels. Community composition of resources was also slightly modified according to soil physico-chemical properties including TM concentrations. Diversity and composition of invertebrate communities were more influenced by diversity of plants than by soil physico- chemical properties. Plant richness in the diet was positively correlated to plant richness in the field in autumn, but not in spring. The seasonal pattern was opposite for invertebrates. Some plant resources, such as Salicaceae, Sapindaceae or Adoxaceae families, were preferred by mice but with seasonal differences. Soil TM contamination reduced mice preference for Salicaceae plants in spring and also modified relationships between richness in the field and diet richness at both seasons. The type of food items consumed by mice affected their trophic exposure to TMs. Consumption of Salicaceae resources, known as TM accumulator plants, increased exposure to Cd and Zn. However, high exposure to Cd induced by Salicaceae was dampened when a large number of other resources were consumed. Concentrations of TMs in plant leaves increased along the gradient of soil TM concentrations in both Salicaceae and Sapindaceae, and concentrations of Cd and Zn in leaves were higher in Salicaceae than in Sapindaceae. Higher bioconcentration factor was observed for Cd in leaves of Salicaceae than in those of Sapindaceae. No change in bioconcentration factor was observed in relation to biodiversity. We finally demonstrated that oral exposure to Pb and accumulation of Cd in the liver and in kidneys of mice decreased along the gradient of plant richness in the field, suggesting a dilution effect.

Material was pitfall trapped in 2010 and 2011 on twelve sites of the agricultural landscape in the Prešov town and its near vicinity, Eastern Slovakia. A total of 14,763 ground beetle individuals were entrapped. Material collection resulted into 92 Carabidae species, with the following six species dominating: Poecilus cupreus, Pterostichus melanarius, Pseudoophonus rufipes, Brachinus crepitans, Anchomenus dorsalis and Poecilus versicolor. Studied habitats differed significantly in the number of entrapped individuals, activity abundance as well as representation of the carabids according to their habitat preferences and ability to fly. However, no significant distinction was observed in the diversity, evenness neither dominance.

L. coecus was found to be the sole representative of the family Lophoproctidae in collections examined from Crimea and the Caucasian region. The species was also identified from Iran and Kyrgyzstan.Lophoproctus specimens collected in Italy by Verhoeff were reassigned as L. coecus with the exception of one specimen of L. jeanneli (Brölemann, 1910) from Capri. These data were combined with all available information from the literature to look at the pattern of distribution of the four species in the genus.

Plants interact with various organisms, aboveground as well as below- ground. Such interactions result in changes in plant traits with consequences for mem- bers of the plant-associated community at different trophic levels. Research thus far focussed on interactions of plants with individual species. However, studying such inter- actions in a community context is needed to gain a better understanding. 2. Members of the aboveground insect community induce defences that systemically influence plant interactions with herbivorous as well as carnivorous insects. Plant roots are associated with a community of plant-growth promoting rhizobacteria (PGPR). This PGPR community modulates insect-induced defences of plants. Thus, PGPR and insects interact indirectly via plant-mediated interactions. 3. Such plant-mediated interactions between belowground PGPR and aboveground insects have usually been addressed unidirectionally from belowground to aboveground. Here, we take a bidirectional approach to these cross-compartment plant-mediated interactions. 4. Recent studies show that upon aboveground attack by insect herbivores, plants may recruit rhizobacteria that enhance plant defence against the attackers. This rearranging of the PGPR community in the rhizosphere has consequences for members of the aboveground insect community.
