Freshwater systems play an active role in  the carbon cycle as it receives, and decomposes, terrestrial litter  material alongside decomposing aquatic plant litter. Decomposition of  organic matter in the aquatic environment is directly controlled by water  temperature and nutrient availability, which are continuously affected by  global change. We adapted the Tea Bag Index (TBI), a highly standardized  methodology for determining soil decomposition, for lakes by incorporating  a leaching factor. By placing Lipton pyramid tea bags in the aquatic  environment for 3 hours, we quantified the period of intense leaching  which usually takes place prior to litter (tea) decomposition. Standard  TBI methodology was followed after this step to determine how fast  decomposition takes place (decomposition rate, k1) and how much of the  material cannot be broken down and is thus sequestered (stabilization  factor, S). A Citizen Science project was organized to test the aquatic  TBI in 40 European lakes located in four climate zones, ranging from  oligotrophic to hypereutrophic systems. We expected that warmer and/or  eutrophic lakes would have a higher decomposition rate and a more  efficient microbial community resulting in less tea material to be  sequestered. The overall high decomposition rates (k1) found confirm the  active role lakes play in the global carbon cycle. Across climate regions  the lakes in the warmer temperate zone displayed a higher decomposition  rate (k1) compared to the colder lakes in the continental and polar zones.  Across trophic states, decomposition rates were higher in eutrophic lakes  compared to oligotrophic lakes. Additionally, the eutrophic lakes showed a  higher stabilization (S), thus a less efficient microbial community,  compared to the oligotrophic lakes, although the variation within this  group was high. Our results clearly show that the TBI can be used to  adequately assess the decomposition process in aquatic systems. Using  \u201calien standard litter\u201d such as tea provides a powerful way to compare  decomposition across climates, trophic states and ecosystems. By providing  standardized protocols, a website, as well as face to face meetings, we  also showed that collecting scientifically relevant data can go hand in  hand with increasing scientific and environmental literacy in  participants. Gathering process-based information about lake ecosystems  gives managers the best tools to anticipate and react to future global  change. Furthermore, combining this process-based information with citizen  science, thus outreach, is in complete agreement with the Water Framework  Directive goals as set in 2010.", "keywords": ["decomposition constant", "Verwerkte data", "European lakes", "european lakes", "Carbon cycle", "15.

The diversity of the surrounding plant community can directly affect  the abundance of insects on a focal plant as well as the size and quality  of that focal plant. However, to what extent the effects of plant  diversity on the arthropod community on a focal plant are mediated by host  plant quality or by the diversity of the surrounding plants remains  unresolved. 2. In the field, we sampled arthropod communities on focal  Jacobaea vulgaris plants growing in experimental plant communities that  were maintained at different levels of diversity (1, 2, 4 or 9 species)  for three years. Focal plants were also planted in plots without  surrounding vegetation. We recorded the structural characteristics of each  of the surrounding plant communities as well as the growth, and primary  and secondary chemistry (pyrrolizidine alkaloids, PAs) of the focal plants  to disentangle the potential mechanisms causing the diversity effects. 3.  Two years after planting, the abundance of arthropods on focal plants that  were still in the vegetative stage decreased with increasing plant  diversity, while the abundance of arthropods on reproductive focal plants  was not significantly affected by the diversity of the neighbouring  community. The size of both vegetative and reproductive focal plants was  not significantly affected by the diversity of the neighbouring community,  but the levels of PAs and the foliar N concentration of vegetative focal  plants decreased with increasing plant diversity. Structural equation  modelling revealed that the effects of plant diversity on the arthropod  communities on focal plants were not mediated by changes in plant quality.  4. Synthesis. Plant quality can greatly influence insect preference and  performance. However, under natural conditions the effects of the  neighbouring plant community can overrule the plant quality effects of  individual plants growing in those communities on the abundance of insects  associated to this plant.", "keywords": ["Phytochemistry", "Jacobaea vulgaris", "plant\u2013herbivore interactions", "plant quality", "insect community", "plant species richness", "Verwerkte data", "phytochemistry", "Processed data", "15.

In addition, unpublished studies from doctoral theses were included  in the dataset. All studies were screened for the following inclusion  criteria and included in the dataset when applicable: (1) studies that  tested the effects of exotic earthworms using an earthworm  treatment/control data or regression data (earthworm biomass or  abundance), if the probability was high that earthworm presence influenced  the respective soil property but not <i>vice versa</i>; (2)  studies that reported at least one of the following soil chemical  properties: pH, water content, stocks or fluxes of C, N, or P; and (3)  studies where control soils had been devoid of native or exotic earthworms  (for studies with treatment/control data).

We  extracted means, variances, and sample sizes of treatments with  (treatment) and without (control) earthworms as well as correlation  coefficients of regressions between earthworm biomass/abundance and soil  chemical properties and sample sizes from regression studies. In addition,  from each study, we extracted information on earthworm species studied,  study type (field observation vs. field experiment vs. lab study),  ecosystem/continent (continent: North America vs. Australia/Oceania;  ecosystem: forest vs. grassland), soil layer (organic vs. mineral), and  the specific target response variable that was measured. We created  additional variables for each of the datasets by assigning ecological  groups to the earthworm species used in the studies, such as the presence  of epigeic, endogeic, and anecic earthworm species, and ecological group  richness. We further included a variable on earthworm species  richness. For earthworm treatment/control data, we  calculated effect sizes for the effects of earthworm invasion on soil  chemical properties using log-response ratio. We ran standard  meta-analyses and tested for total heterogeneity of effect sizes within  each model. We explored potential publication bias using funnel plots for  visual inspection.
