Data from: Temporal dynamics of plant-soil feedback and root-associated fungal communities over 100 years of invasion by a non-native plant
1. Pathogens can accumulate on invasive plants over time, which could lead to population declines. The time required for these dynamics to occur is unknown and seldom addressed. Furthermore, no study has assessed plant-soil feedback while characterising plant pathogen and mutualist root fungal communities in the context of invasion time. 2. We used a plant-soil feedback study and 454 pyrosequencing to investigate pathogen accumulation over 100 years on a highly invasive plant in eastern North America that shows localised declines, Vincetoxicum rossicum (Apocynaceae). 3. We collected soil from five sites representing each of four invasion periods of V. rossicum across Ontario, Canada (old, ~100 years; intermediate, 50-60 years; young, <12 years; and uninvaded), and grew V. rossicum in these soils in a glasshouse study. Our hypothesis was that plants grown in soils invaded for longer periods of time would experience less positive feedbacks compared to those grown in more recently invaded or uninvaded soils. We collected roots of V. rossicum from the invasion periods and performed 454 pyrosequencing targeting fungi. We hypothesised that the abundance and richness of fungi that are known plant pathogens would be higher in roots from older invasions compared to more recent invasions. 4. Contrasting with our hypothesis, V. rossicum experienced overall growth promotion due to soil biota, regardless of invasion period. Vincetoxicum rossicum roots were colonised by a large number of fungal taxa, including many known plant pathogens or mutualistic arbuscular mycorrhizal fungi. However, we found no evidence of pathogen accumulation in older invaded sites in terms of species composition, richness or abundance. 5. Synthesis: Our consistent results in the glasshouse and the field highlight the strength of combining high-throughput sequencing data with plant-soil feedback experiments. We showed that the roots of Vincetoxicum rossicum (Apocynaceae) were colonised by many fungal taxa, but found no evidence for changes in plant growth or accumulation of fungal pathogens with longer invasion time. High pathogen loads may not lead to concurrent declines in invasive plants. Plant invasions, as demonstrated by V. rossicum, may be unpredictable in their ability to accumulate pathogens capable of leading to population declines.
Data from: Genomic reconstruction of 100 000-year grassland history in a forested country: population dynamics of specialist forbs
Grassland ecosystems worldwide have been extensively converted to other land uses and are globally imperiled. Because many grasslands have been maintained by human activities, understanding their origin and history is fundamentally important to better contemporary management. However, existing methods to reconstruct past vegetation can produce contrasting views on grassland history. Here, we inferred demographic histories of 40 populations of four grassland forb species throughout Japan using high-resolution genome sequences and model-flexible demographic simulation based on the site frequency spectrum. Although two species showed a slight decline in population size between 100 000–10 000 years ago, our results suggest that population sizes of studied species have been maintained within the range of 0.5–2.0 times the most recent estimates for at least 100 000 years across Japan. Our results suggest that greater than 90% declines in Japanese grasslands and subsequent losses of grassland species in the last 100 years are geologically and biologically important and will have substantial consequences for Japanese biota and culture. People have had critical roles in maintaining disturbance-dependent grassland ecosystems and biota in this warm and wet forested country. In these contexts, disturbances associated with forest harvesting and traditional extensive farming have the potential to maintain grassland ecosystems and can provide important opportunities to reconcile resource production and conservation of grassland biodiversity.
Strolling through a century: replicating historical bird surveys to explore 100 years of change in an urban bird community
<p>In 1898, Herbert and Alice Walter started a 5-year survey of birds in Lincoln Park, – the largest park in Chicago, IL – and summarized their data in an urban birding field guide, 'Wild Birds in City Parks'. Twenty-nine years later, William Dreuth compared the relative frequency of species between the Walter's study to their own 5-year Lincoln Park survey. Between 2012 and 2015, we replicated these surveys to investigate a century of bird diversity and community composition change in urban Chicago. While species richness did not change, community composition did. We found that 1) species with a greater diet breadth and 2) species that increased in statewide occupancy were more likely to increase in frequency over time. We conclude that factors at multiple scales brought temporal changes to Chicago's bird community. Overall, this survey highlights the slow and subtle ways in which species may respond to a century of urban intensification.</p>

Data from: Isotopic niches of tropical birds reduced by anthropogenic impacts: A 100-year perspective
<p>The intensification of land use changes in tropical forests during the 20<sup>th</sup> century, mainly caused by deforestation for agricultural uses, had an overwhelming influence on bird assemblages. However, how these historical anthropogenic changes have impacted the habitat use and diet of tropical birds is poorly known. Stable isotope analysis (<i>δ</i><sup>13</sup>C and <i>δ</i><sup>15</sup>N) can be useful in this regard since it provides information not only on the habitat and food resource use but also insights on the dietary niche of species. Here, we aimed to evaluate whether centenary anthropogenic impacts, mainly caused by changes in landscape composition, have affected the resource and habitat use and isotopic niche width of Neotropical birds in a region that comprises two biodiversity hotspots — the Atlantic Forest and Cerrado in southeastern Brazil. We found that the niche width of all bird guilds (frugivore, granivore, insectivore, nectarivore, and omnivore) was largely reduced (28–70%) from the twentieth century until recently. This niche width reduction was likely associated with historical anthropogenic impacts (e.g., fragmentation, forest loss and change in agricultural practices), which are responsible for the decrease in the availability of habitat and food resources. Moreover, the mean values of <i>δ</i><sup>15</sup>N decreased over the years in all bird guilds, which might be attributed to the expansion of agricultural areas and the increase in the use of synthetic nitrogen-based fertilizers. All the analyzed species, even though some of them are diet and habitat generalists, were strongly influenced by centenary anthropogenic actions. Our results show the consequences of human-induced changes in land use on the diet and habitat use of tropical birds that persist in fragmented landscapes, which might compromise their long-term survival, and provide useful information to the conservation strategies of bird assemblages in modern landscapes.</p>
