Dataset for the project "The role of expansive and invasive plant species in shaping the activity of microbial communities and carbon sequestration in the soil of post-mining spoil heaps."
<p>Description of the project: Research on carbon sequestration in all types of ecosystems, including human-transformed oligotrophic ecosystems, has become more important today from a climate change perspective, as it can help mitigate its effects. Increasing the potential for C sequestration on brownfield sites can be achieved by improving biological processes and developing soil organic matter reservoirs. This may be particularly relevant for the functioning of oligotrophic ecosystems such as waste coal mine spoil heaps. In studies conducted to date on soil carbon dynamics, it has been found that carbon storage capacity is related to vegetation type, among other factors. This is mainly due to the fact that different plant species affect the physical and chemical properties of the soil, the chemical composition of the litter, detritus supply and rooting depth differently. Furthermore, plant species have been shown to influence the composition and biomass of soil microbial communities, and these microorganisms are responsible for the decomposition of organic compounds in the soil. There is little knowledge of soil microbial communities and their activities in the different plant communities of post-mining spoil heaps, especially with regard to the effects of specific microbial communities on soil carbon sequestration. The aim of the project was to compare the influence of a native expansive grass species (<em>Calamagrostis epigejos</em> (L.) ROTH) and an alien invasive species (<em>Solidago gigantea</em> AITION) on the activity and structure of soil microorganisms and carbon sequestration on post-mining spoil heaps spontaneously colonised by vegetation and subjected to reclamation. The study was carried out on a model post-mining heap, part of which has been reclaimed with overburdened soil, while the remaining part has not undergone any reclamation and is subject to spontaneous succession processes. An analysis of total organic carbon (TOC) in soil substrate samples was carried out to determine the effect of the plant species studied on carbon sequestration. TOC consists of organic compounds mainly derived from root exudates, microbial biomass and decomposition of plant litter and SOM by microorganisms. Therefore, the structure of soil microbial assemblages was also investigated by means of phospholipid fatty acid profiles and the activity of these microorganisms, by means of soil enzyme analysis and functional diversity of microorganisms using BIOLOG<sup>®</sup> Ecoplates. In addition, the in situ level of CO<sub>2</sub> release from the soil was also determined.</p>
Data from: Retracing the routes of introduction of invasive species: the case of the Sirex noctilio woodwasp.
Understanding the evolutionary histories of invasive species is critical to adopt appropriate management strategies, but this process can be exceedingly complex to unravel. As illustrated in this study of the worldwide invasion of the woodwasp Sirex noctilio, population genetic analyses using coalescent-based scenario testing together with Bayesian clustering and historical records provide opportunities to address this problem. The pest spread from its native Eurasian range to the Southern Hemisphere in the 1900's and recently to Northern America, where it poses economic and potentially ecological threats to planted and native Pinus spp. To investigate the origins and pathways of invasion, samples from five continents were analysed using microsatellites and sequence data. Surprisingly, clustering analyses revealed two gene pools. Scenario testing showed independent introductions from an unsampled source, putative source of the second gene pool. The invasion history was much more complex than previously believed, with most of the populations being admixtures resulting from independent introductions from Europe and subsequent spread among the invaded areas. Results also shed light on the micro-evolutionary processes occurring during introductions, and showed that only few specimens gave rise to some of the populations. Analyses of microsatellites using clustering and scenario testing considered against historical data drastically altered our understanding of the invasion history of S. noctilio and will have important implications for the strategies employed to fight its spread. This study illustrates the value of combining clustering and ABC methods in a comprehensive framework to dissect the complex patterns of spread of global invaders.
Data from: Invasive species reduces parasite prevalence and neutralizes negative environmental effects on parasitism in a native mosquito
1.Invasive species research often focuses on direct effects of invasion on native ecosystems and less so on complex effects such as those influencing host‐parasite interactions. However, invaders could have important effects on native host‐parasite dynamics. Where infectious stages are ubiquitous and native host‐pathogen specificity is strong, invasive less‐competent hosts may reduce the pool of infectious stages, effectively reducing native host‐parasite encounter rate. Alternatively, invasive species could alter transmission via changes in native species abundance. 2.Biotic and abiotic environmental factors can also impact disease dynamics by altering host or parasite condition. However, little is known about potential interactive effects of invasion and environmental context on native species disease dynamics. Moreover, experimental examinations of the mechanisms driving dilution effects are limited, but serve to provide tests of predictions leading to diversity‐disease relationships. 3.Using field and laboratory experiments, we tested competing hypotheses that an invasive species reduces the prevalence of a native parasite in its host by removing infectious propagules from the environment or by reducing native host abundance. In addition, we evaluated the role of detritus quantity as a resource base in mediating effects of the invasive species. 4.Native parasite prevalence was reduced when the invasive species was present. Prevalence was also higher in high detritus habitats, although this effect was lost when the invasive species was present. The invasive species significantly reduced infectious propagules from the aquatic habitats. Presence of the invasive species had no effect on the native species abundance; thus, the reduction in parasitism was not due to changes in host density but through a reduction in infectious propagule encounters. 5.We conclude that an invasive species can facilitate a native species by reducing parasite prevalence via a dilution effect and that these effects can be modified by resource level. Reductions in parasitism may have ripple effects throughout the community, altering the strength of competitive interactions, predation rates, or coinfection with other pathogens. We advocate considering potential positive effects of invasive species on recipient communities, in addition to effects of invasions on host‐parasite interactions to gain a broader understanding of the complex consequences of invasion.
Data from: Multispecies invasion reduces the negative impact of single alien plant species on native flora
Aim: In the current Anthropocene, many ecosystems are being simultaneously invaded by multiple alien species. Some of these invasive species become more dominant and have greater environmental impacts than others. If two potentially dominant species invade the same area, the combined impact has been reported to be either (1) domination by one species, i.e., the competitive dominance of one invader, or (2) invasion meltdown, where the combined impact is much greater, i.e., a synergistic effect. We studied the effects of the invasion of two alien plant species that are known to strongly decrease native plant species diversity: the Persian walnut Juglans regia and goldenrod Solidago canadensis. Location: We examined native vegetation diversity in abandoned fields (in Poland) where neither species had invaded, only one species had invaded, and both species had invaded. Methods: Field survey data were analysed using generalized linear mixed models and ordination techniques. Results: When goldenrod invaded alone, it caused a larger decrease in species richness and cover (74%) than when walnut invaded alone (58%). ¬When walnut and goldenrod co-occurred in abandoned fields, walnut was dominant and strongly decreased goldenrod density by 87%. However, the combined impact on native species diversity was much lower (15% decrease in native plant diversity) than when either goldenrod or walnut invaded alone. Main conclusions: In contrast to many other studies, our study does not support the occurrence of an invasion meltdown. Instead, our results show that even when one invader dominates, its negative effect on plant diversity can be strongly modified by the presence of another invasive species.
