Data set on the impact of selected plant protection products on ecosystem service providers, including interactive effects
<p>The Excel files contain the results of ecotoxicological tests for the effects of selected insecticides on ESP species. The objective of this dataset is to provide original data from acute and semi-chronic laboratory tests on a few important beneficial species with broad geographic distribution. The data allow the evaluation of delayed effects and possible interactive effects of combined treatments for those pesticides that are commonly used in mixtures or sprayed next to each other in short time intervals, effectively exposing non-target arthropods to combined/sequential effects. Each data file contains the “Description” sheet where all details of the test and the exact meaning of data fields in the database are reported. The data files are named in a self-explanatory manner, starting with the name of the institution that produced the data (UC – University of Coimbra; UJA – Jagiellonian University), followed by the name of the tested species and names of tested products.</p>
Data from: Plant protection services mediated by extrafloral nectaries decline with aridity but are not influenced by chronic anthropogenic disturbance in Brazilian Caatinga
<p>1. Most terrestrial species occur in human-modified landscapes that are experiencing climate change. In addition to direct impacts on species, both anthropogenic disturbance and climate change can have important effects through changes in species interactions, including the disruption of ecological services provided by them.</p> <p>2. Here we investigate how chronic anthropogenic disturbance (CAD) and aridity affect the effectiveness of plant protection services provided by ants to plants bearing extrafloral nectaries (EFNs).</p> <p>3. The study was conducted across 13 01-ha plots distributed along CAD and aridity gradients in Caatinga vegetation of northeastern Brazil. We focused on Pityrocarpa moniliformis, the most abundant and widely distributed EFN-bearing tree species occurring in our study area, and used experimental attack rates on termites as a measure of effectiveness of ant protection services. We investigated the relative roles of nectar production (volume and concentration) and ant species composition in mediating the effects of CAD and aridity on the effectiveness of protection services.</p> <p>4. Attack rates by ants declined with increasing aridity but were not related to CAD. The volume of extrafloral nectar declined with increasing CAD but was not affected by aridity, whereas the concentration was not related to either CAD or aridity. The composition of attendant ant species varied with aridity but not with CAD.</p> <p>5. Synthesis: The decline in ant-protection services with increased aridity was therefore mediated by changes in the composition of attendant ant species rather than by changes in the production of extrafloral nectar. Our findings suggest that CAD does not affect plant-protection services provided by ants but highlights the vulnerability of EFN-bearing plants to climate change through decreased predation of herbivores.</p>
Functional composition of plant communities mediates biomass effects on ecosystem service recovery across an experimental dryland restoration network
<p>Land degradation can result in a loss of critical ecosystem services that we often seek to restore through re-establishment of desired plant communities. Trait-based approaches have the potential to target specific ecosystem services based on associations between the functional composition of plant communities and ecosystem properties that serve as indicators of those services. The effect of functional composition on ecosystem recovery may depend on the amount of restored plant biomass, itself a supporting service frequently targeted in restoration efforts. Yet, interactions between functional composition and biomass are not formally integrated into trait-based analytical frameworks. We tested the hypothesis that functional composition of plant communities both drives, and interacts with, biomass production to influence indicators of soil functioning and weed suppression across a network of degraded dryland restoration experiments. This networked approach allowed us to identify generalized effects of functional composition on ecosystem recovery across a range of dryland climate conditions. Climate had a substantial effect on ecosystem indicators, with weed cover and soil surface stability increasing in more arid climates, water infiltration increasing with precipitation, and aggregate structure increasing with less freezing. After accounting for climate effects across study sites, we found significant effects of community-weighted mean (CWM) trait values on biomass, particularly a positive effect of leaf carbon-to-nitrogen ratio, and of CWM-biomass interactions on other ecosystem indicators. Cover of exotic species was reduced in restored communities with a combination of low leaf dry matter content and high biomass, soil water infiltration increased with lower specific root length and high biomass, and soil aggregate stability increased with higher root dry matter content and high biomass, among other effects. Functional diversity had no significant effects on any ecosystem indicators. Synthesis: The influence of community functional composition on ecosystem properties increases with community biomass, particularly in disturbed or low productivity systems. This suggests that active management should not only focus on trait values that optimize individual ecosystem indicators, but also how those functional strategies are complementary or counter to those that increase biomass.</p>

Flower traits, habitat and phylogeny as predictors of pollinator service: a plant community perspective
<p>Pollinator service is essential for successful sexual reproduction and long-term population persistence of animal-pollinated plants, and innumerable studies have shown that insufficient service by pollinators results in impaired sexual reproduction ("pollen limitation"). Studies directly addressing the predictors of variation in pollinator service across species or habitats remain comparatively scarce, which limits our understanding of the primary causes of natural variation in pollen limitation. This paper evaluates the importance of pollination-related features, evolutionary history and environment as predictors of pollinator service in a large sample of plant species from undisturbed montane habitats in southeastern Spain. Quantitative data on pollinator visitation were obtained for 191 insect-pollinated species belonging to 142 genera in 43 families, and the predictive values of simple floral traits (perianth type, class of pollinator visitation unit, and visitation unit dry mass), phylogeny, and habitat type were assessed. A total of 24,866 pollinator censuses accounting for 5,414,856 flower-min of observation were conducted on 510 different dates. Flowering patch and single flower visitation probabilities by all pollinators combined were significantly predicted by the combined effects of perianth type (open vs. restricted), class of visitation unit (single flower vs. flower packet), mass of visitation unit, phylogenetic relationships, and habitat type. Pollinator composition at insect order level varied extensively among plant species, largely reflecting the contrasting visitation responses of Coleoptera, Diptera, Hymenoptera and Lepidoptera to variation in floral traits. Pollinator composition had a strong phylogenetic component, and the distribution of phylogenetic autocorrelation hotspots of visitation rates across the plant phylogeny differed widely among insect orders. Habitat type was a key predictor of pollinator composition, as major insect orders exhibited decoupled variation across habitat types in visitation rates. Comprehensive pollinator sampling of a regional plant community has shown that pollinator visitation and composition can be parsimoniously predicted by a combination of simple floral features, habitat type and evolutionary history. Ambitious community-level studies can help to formulate novel hypotheses and questions, shed fresh light on long-standing controversies in pollination research (e.g., "pollination syndromes"), and identify methodological cautions that should be considered in pollination community studies dealing with small, phylogenetically-biased plant species samples.</p>
Data from: A survey of invasive plants on grassland soil microbial communities and ecosystem services
<p>Invasive plants can cause changes in structure and function of the ecosystem undergoing invasion. Any changes in ecosystem diversity and community composition will likely alter ecosystem services provided by that ecosystem. However, how these ecosystem services may change is poorly understood. To elucidate how these ecosystem services will change with invasion, we sampled 561 plots undergoing invasion by smooth brome (<i>Bromus inermis</i>) and four other invasive species at a native Rough Fescue prairie located near Saskatoon, Saskatchewan, Canada. Soil and plant surveys were undertaken weekly for 26 weeks beginning in May in 2014 until November 2014, or the growing season. We measured a suite of ecosystem services, including greenhouse gasses, extracellular enzyme function, forage production, glyphosate degradation and decomposition. Furthermore, soil physical and chemical properties were measured, and soil bacterial and fungal communities were sequenced. This is a large and multifaceted dataset with complex temporal and spatial attributes that can be used to answer numerous questions regarding the functioning of prairie ecosystems and how invasive species will impact that functioning. </p>
Data from: Ecosystem services provided by bromeliad plants: a systematic review
The unprecedented loss of biological diversity has negative impacts on ecosystems and the associated benefits which they provide to humans. Bromeliads have high diversity throughout the Neotropics, but they have been negatively affected by habitat loss and fragmentation, climate change, herbivorous species invasions, and they are also being commercialized for ornamental use. These plants provide direct benefits to the human society and they also form micro ecosystems in which accumulated water and nutrients support the communities of aquatic and terrestrial species, thus maintaining local diversity. We performed a systematic review of the contribution of bromeliads to ecosystem services across their native geographical distribution. We showed that bromeliads provide a range of ecosystem services such as maintenance of biodiversity, community structure, nutrient cycling, and the availability of food and water. Moreover, bromeliads can regulate the spread of diseases, water and carbon cycling, and they have the potential to become important sources of chemical and pharmaceutical products. The majority of this research was performed in Brazil, but future research from other Neotropical countries with a high diversity of bromeliads would fill the current knowledge gaps, and increase the generality of these findings. This systematic review identified that future research should focus on provisioning, regulating and cultural services that have been currently overlooked. This would improve our understanding of how bromeliad diversity contributes to human welfare, and the negative consequences that loss of bromeliad plants can have on communities of other species and the healthy functioning of the entire ecosystems.
Chimpanzees as ecosystem service providers: Seed dispersal of an economically important plant resource
<p class="Body">Vertebrate-mediated seed dispersal is vital to the maintenance of diversity in tropical ecosystems, and seed-dispersing animals are increasingly thought to provide ecosystem services by dispersing the seeds of plant species utilized by people. However, few studies have demonstrated a link between vertebrate frugivores and plants used by people, thus limiting the generalizability of the seed-disperser-as-ecosystem-service-provider concept. We examined the effectiveness of western chimpanzees (<em>Pan troglodytes verus</em>) as seed dispersers (i.e., their influence on seedling recruitment) of an economically important fruit resource, <em>Saba senegalensis</em>, at the site of Fongoli, a savanna-woodland environment in southeastern Senegal. The fruit from the <em>Saba</em> vine is commonly harvested from the wild by local people and is also an important food item for chimpanzees. We conducted germination experiments on gut-passed seeds alongside non-gut-passed seeds and analyzed the germination success of chimpanzee-dispersed seeds <em>in situ</em>. We also analyzed the effect of habitat type and canopy cover at each seed dispersal site to determine which sites are most suitable for <em>Saba</em> germination. Germination trials showed that chimpanzee gut passage and manual pulp removal increased the likelihood of germination over seeds left intact. Nearly a quarter of chimpanzee-dispersed seeds germinated <em>in situ</em> and <em>Saba</em> seeds were distributed non-randomly throughout Fongoli, with more dispersed seeds found in habitats most suitable for <em>Saba</em> germination. These results suggest that chimpanzees aid in the early stages of <em>Saba</em> recruitment and thus provide an ecosystem service via seed dispersal that may contribute to the well-being of local people.</p>
Proximity to natural habitat and flower plantings increases insect populations and pollination services in South African apple orchards
<p><span><span><span><span><span><span><span><span><span><span><span>Introducing areas of wildflower vegetation within crop fields has been shown to enhance pollinator activity and pollination services to crops, and findings in Europe showed an interaction effect between floral treatments and landscape context. Natural fynbos patches in the South African Cape Floristic Region (CFR) are potential reservoirs for beneficial insects that could enhance pollinator populations and crop pollination in commercial apple orchards.
