“…In eastern forests, the invasive understory shrub, Lonicera maackii (Amur honeysuckle) broadly overlaps with white‐tailed deer and negatively affects native herbaceous plants, shrubs, and saplings (McNeish and McEwan ). Further, there is evidence that honeysuckle invasion supports higher deer density in some landscapes (Allan et al.…”

Recent studies have shown that complex species interactions can regulate above‐ and belowground processes in terrestrial systems. Ungulate herbivory and invasive species are known to have strong effects on plant communities in some systems, but their impacts on soil biota and belowground processes are lesser known. Growing evidence suggests white‐tailed deer (Odocoileus virginianus) and invasive plants facilitate increased abundance of exotic earthworms in temperate forests of the eastern United States. We conducted an experimental study that manipulated deer access and the presence of an invasive understory shrub in an eastern deciduous forest of southwestern Ohio, USA, from 2013 to 2017. Earthworm density and biomass, and standing litter biomass were measured in five paired deer access and exclosure plots, each with a split‐plot removal of Amur honeysuckle (Lonicera maackii). Earthworm density declined in response to the experimental exclusion of deer, with earthworm density decreasing over time in the deer exclosure plots relative to deer access plots. Deer exclusion produced greater variation in earthworm species composition relative to access plots. Multivariate analyses indicated that larger earthworms in the genus Lumbricus were associated with deer exclosure plots, while smaller endogeic species were ubiquitous in both treatments. Standing litter biomass decreased over time in the deer‐access plots. In contrast, honeysuckle removal had little effect on earthworm density and standing litter biomass. There was an interaction between deer and honeysuckle treatments on earthworm biomass, with honeysuckle removal reducing earthworm biomass when deer were excluded. Our results demonstrate strong effects of herbivores on invasive earthworms and ecosystem processes, but indicate a weaker influence of invasive shrubs. Further, our findings suggest that the effects of deer overabundance in forest ecosystems are potentially reversible with long‐term intervention.

Differential responses to global change of aquatic and terrestrial invasive species: evidences from a meta‐analysis

et al. 2019

Increases in carbon dioxide (CO2), temperature, and precipitation can have varying effects on environmental conditions and resources affecting species’ performance and overall function of native and non‐native species that may influence future biodiversity. More attention is being focused on how climate change impacts the performance of co‐occurring native and introduced species. No synthesis has solely examined how invasive plant and animal species perform under climate change across both terrestrial and aquatic habitats. We asked the following questions: (1) How will combined and single climate change factors influence the performance of non‐native species? (2) Which habitat types are more affected by climate factors in a combined or single manner? (3) What guilds/functional groups, within aquatic vs. terrestrial habitats, are more impacted by climate factors? To better understand this, we conducted a meta‐analysis examining the relative influence climate change factors (carbon dioxide (CO2)/acidification, temperature, precipitation) have on invasive species’ performance. Our results indicate that global change factors had an overall increased performance on invasive species in terrestrial habitats with an opposite effect observed in aquatic habitats. Plant functional groups were positively affected, whereas animal guilds were generally negatively impacted by global changes. Our findings suggest that while invasive taxa are affected differently by global changes, responses are confounded by habitat type, and, therefore, to fully understand global change impacts on invasive taxa, increased representation of animal studies in terrestrial systems and plants in aquatic systems is needed.

“…It is also critical to consider the extent to which such correlations are consistent with hypotheses and conceptual frameworks that are grounded in ecological theory and experiments (Hulme et al., ; Ricciardi et al., ), such as ecological stoichiometry or mass balance of nutrient cycles. Common buckthorn and other invasive shrubs in North America, such as Frangula alnus and Lonicera spp., are known to have high concentrations of nutrients in their leaves and leaf litter (Jo et al., , ; McNeish & McEwan, ; Figure ) and many experiments show that plants with such traits have unique impacts on soil biota and nutrient cycles (Curry & Schmidt, ; Lee et al., ). For example, both experimental observations and theory related to ecological stoichiometry show that soil biota such as earthworms should achieve greater growth and population size when consuming litter that better matches their own nutrient stoichiometry (Hobbie et al., ; Ott et al., ), such as calcium‐rich buckthorn litter (Figure ).…”

Short‐term experiments cannot characterize how long‐lived, invasive shrubs influence ecological properties that can be slow to change, including native diversity and soil fertility. Observational studies are thus necessary, but often suffer from methodological issues. To highlight ways of improving the design and interpretation of observational studies that assess the impacts of invasive plants, we compare two studies of nutrient cycling and earthworms along two separate gradients of invasive shrub abundance. By considering the divergent sampling strategies and statistical analyses of these two studies, and interpreting their contradictory results in the context of other studies, we also aim to better describe the impacts of the focal invader, Rhamnus cathartica. In a new study of a single site in Minnesota, we observed positive correlations between buckthorn abundance and soil pH, soil nutrient pools, nutrient fluxes through leaf litterfall, earthworm abundance and root biomass. Multiple regression models showed these relationships persisted after accounting for variability in soil texture and tree species composition. For a separate, more expansive study in Illinois, other authors reported little to no correlation between buckthorn abundance and 10 soil properties, including earthworm abundance, pH and nutrient concentrations. However, like many other studies, their regression models only assessed predictors related to invader abundance. R2‐values for models of ecosystem properties ranged from 0 to .79 (adjusted‐R2) for our study in Minnesota and from <.05 to .16 (unadjusted) for the prior study in Illinois. Differences in sampling error and use of predictor variables between the two studies likely explain the contrasting results. Synthesis and applications. To reduce the uncertainty of conclusions from observational studies of invasive plants, future studies must ensure that heterogeneity of soils and vegetation is adequately accounted for in the sampling strategy and statistical analyses (e.g. analysis of covariance, multiple regression). Particular attention should be given to ecosystem properties with variability that likely pre‐dates the invader (e.g. geophysical features and tree community composition). In our study, effects of buckthorn on ecosystem properties were not only robust to the inclusion of potentially confounding predictors, but also consistent with expectations based on ecological stoichiometry and mass balance of element flow.
