Litter chemistry and decomposition rates are relevant factors to understand the invasion process due to its influence on nutrient cycling and ecosystem dynamics. Here, we present the results of a litterbag mesocosm comparing the decomposition dynamics of litter produced by two common IAPs (<i>Acacia dealbata</i> and <i>Carports edulis)</i> with similar amounts of native litter from invaded ecosystems (shrubland and coastal dunes invaded by <i>A. dealbata</i> and <i>C. edulis</i>, respectively), and how this different leaf litter origin further affects soil community function and the growth of seedlings of different native species. After 12 months of incubation, plant litter decayed at a rate of between 54 and 36% (<i>C. edulis</i> litter > dune litter and Shrub litter > <i>A. dealbata</i> litter) with slight changes in nutrient composition (C, N, C:N, and P content) at the end of the assay. Whereas the effect of the litterbag content (native vs. non-native plant litter) was rather limited, the incubation time significantly affected physico-chemical parameters. Thus, extracellular enzymatic activities (EAs, including acid and basic phosphatase, β-glucosidase, urease) varied depending on the litterbag content (native and non-native) for both decomposing species (<i>A. dealbata</i> or <i>C. edulis</i>). The correspondence analysis (CA) based on the community level physiological profile (CLPPs) showed a similar trend of data clustering regardless of the IAP considered. In both cases, different decomposition times were more relevant than litter origin to discriminate the soil functional activity. Finally, seedlings of different native species were grown in soils previously used for the litter incubation experiment. Here, seedlings of native species growing in soils from the mesocosm (previously covered with native or invasive litter) showed a species-dependent response. At the end of the assay, slight differences were found between the invasive and native plant litter. The results of the decomposition rates between litter of different origin, the effect of litter origin on soil nutrient content, on extracellular EAs, on the functional profile of soil communities, and also on the performance of native seedlings can be considered as limited. These results suggest that litter chemistry might not be as relevant as previously suggested—at least not relevant to explain ecosystem-level alterations—while highlighting the importance of assessing invasion thresholds rather than litter chemical composition.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"8 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141939356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationships of soil characteristics (e.g., pH) with OTU composition were independent of plant nativity and mycorrhizal type.

Irrespective of plant type, OTU composition was distinct among plant species, particularly in fungal communities associated with the invader <i>Rhamnus cathartica</i>.

In this study, using an analytical framework, we investigate the individual and combined effects of two global plant invaders (<i>Leucanthemum vulgare</i> and <i>Lupinus polyphyllus</i>) on the aboveground vegetation (plant richness, diversity and biomass) and belowground soil variables (pH, salinity, electrical conductivity, total dissolved solids, organic carbon [OC], phosphorous, and potassium) of grassland communities in the Himalaya. We studied these ecological variables in comparable plots under the following four scenarios: both invaders absent (i.e. uninvaded), either of the two invaders present (i.e. single species invasion), and both invaders present (i.e., co-invasion). Our results show invasion effects vary with the invasion scenarios and the studied variables. The single species invasion plots had lower mean plant richness and diversity but higher mean soil OC than the uninvaded plots. The co-invasion plots had significantly increased mean plant biomass and soil OC, but had a non-significant effect on plant richness and diversity compared to the uninvaded plots. The overall combined effect of species’ co-invasion was additive in nature, but the effect varied significantly with choice of the response variable. We found synergistic effects of co-invasion on species richness and diversity, antagonistic effects on soil pH, and additive effects on the remaining response variables when compared with the predicted additive effect of the two invaders. Our findings suggest that further spread of <i>L. polyphyllus</i> will impact the resident plant community more severely when co-invading with <i>L. vulgare</i> than when invading alone, thereby lending support to the invasional meltdown hypothesis. Nevertheless, antagonistic and additive impacts for soil pH and other response variables respectively hint towards other alternate mechanisms at play. Overall, our study showcases a proof-of-concept to empirically estimate the additive, antagonistic and synergistic impacts of plant co-invasions, and also provides a model for designing co-invasion studies on other taxa/systems/scales elsewhere.

One such interaction that has received little attention is the phenomenon of ‘serial replacement’ or ‘over-invasion’, where an established invasive species is supplanted by a second invasive species. Understanding this interaction is important as controlling the second species could inadvertently lead to an increase in the abundance of the first species. We used a hierarchical state-space model to analyse changes in annual abundances (commercial catch-per-unit-effort) of three invasive fish species, tench (<i>Tinca tinca</i>), common carp (<i>Cyprinus carpio</i>) and redfin perch (<i>Perca fluviatilis</i>), in the Murray-Darling River system (MDRS), Australia between 1954–2002. Tench were present at low abundances until the mid-1970 s, before declining to the point of no commercial catch post-1989. This rapid decline coincided with a significant increase in carp abundance, suggesting that carp may have driven the tench decline through habitat modification (particularly the destruction of aquatic plants), consistent with findings from European studies that show the disappearance of tench from ponds with intensive carp farming. Redfin perch populations, were inferred to be much less impacted by the invading carp population. While carp were present in the MDRS for the duration of the study, the rapid increase in carp abundance in the early 1970 s coincided with the introduction of a specific genetic lineage—the “Boolarra strain”. Our analysis provides compelling evidence of serial replacement of long-established tench by invading common carp triggered by the introduction of a novel carp strain.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"311 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141939360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A statistical model linking the resulting Russian olive percent cover detection map to environmental variables for the entire watershed indicated Russian olive cover increased with flow accumulation and decreased with elevation, and was associated with poorer soil types. We attribute the success of Russian olive to its broad habitat suitability combined with changing hydrologic conditions favoring it over natives.
