“…By selectively damaging particular plant species, insect herbivores alter competitive relationships and thus codetermine species local abundances (Borgström et al 2016, Engelkes et al 2016). Though it has rarely been examined (Smith‐Ramesh and Reynolds 2017), herbivores can also differently influence individuals within a single species (Bezemer et al 2005, Heinze and Joshi 2018, Heinze et al 2019, Kirchhoff et al 2019). These studies suggest a potentially strong interaction between PSF and aboveground herbivory, though they have generally been performed in greenhouse and not in field conditions (e.g., Bezemer et al 2005, Engelkes et al 2008, Kos et al 2015; but see, e.g., Heinze and Joshi 2018, Hannula et al 2019).…”

Relatively little is known about how plant-soil feedbacks (PSFs) may affect plant growth in field conditions where factors such as herbivory may be important. Using a potted experiment in a grassland, we measured PSFs with and without aboveground insect herbivory for 20 plant species. We then compared PSF values to plant landscape abundance. Aboveground herbivory had a large negative effect on PSF values. For 15 of 20 species, PSFs were more negative with herbivory than without. This occurred because plant biomass on "home" soils was smaller with herbivory than without. PSF values with herbivory were correlated with plant landscape abundance, whereas PSF values without herbivory were not. Shoot nitrogen concentrations suggested that plants create soils that increase nitrogen uptake, but that greater shoot nitrogen values increase herbivory and that the net effect of positive PSF and greater aboveground herbivory is less aboveground biomass. Results provided clear evidence that PSFs alone have limited power in explaining species abundances and that herbivory has stronger effects on plant biomass and growth on the landscape. Our results provide a potential explanation for observed differences between greenhouse and field PSF experiments and suggest that PSF experiments need to consider important biotic interactions, like aboveground herbivory, particularly when the goal of PSF research is to understand plant growth in field conditions.

“…Patterns of seedling performance that fit the predictions of negative intraspecific PSFs have been demonstrated in a handful of plant species (Bukowski & Petermann, 2014;Liu et al, 2015;Bukowski et al, 2018;Eck et al, 2019;Kirchoff et al, 2019;Crawford & Hawkes, 2020), but positive intraspecific PSFs can also occur (Bukowski & Petermann, 2014), as well as lack of intraspecific PSFs in some species (Rallo et al, 2023). Furthermore, existing evidence of intraspecific PSFs arises primarily from experiments conducted under controlled conditions (but see Browne & Karubian, 2016;Kirchoff et al, 2019). In a prior shadehouse experiment, we found that seedlings of a tropical tree species (Virola surinamensis) had reduced growth in the soil microbial community from beneath their maternal tree relative to the soil microbial community from beneath non-parent conspecific trees in their population (Eck et al, 2019).…”

“…Recent experimental evidence suggests that intraspecific PSFs can occur within populations (Eck et al, 2019; Crawford & Hawkes, 2020) and among populations (Bukowski & Petermann, 2014; Liu et al, 2015; Wagg et al, 2015; Bukowski et al, 2018; Kirchoff et al, 2019) of the same plant species. Intraspecific PSFs can be characterized by variation in the performance of closely related seedlings (e.g., offspring) versus unrelated seedlings when exposed to the soil microbial communities of conspecific adults within their population.…”

PremiseSoil microbes can influence patterns of diversity in plant communities via plant-soil feedbacks. Intraspecific plant-soil feedbacks occur when plant genotype causes variation in soil microbial composition, resulting in differences in the performance of seedlings growing near their maternal plants versus seedlings growing near non-maternal conspecific plants. How commonly such intraspecific plant-soil feedbacks occur in natural plant communities is unclear, especially under variable field conditions.MethodsWe conducted an in situ experiment with four native tree species on Barro Colorado Island (BCI), Panama. Seedlings of each species were transplanted beneath their maternal tree or another conspecific tree in the BCI forest. Mortality and growth were assessed at the end of the wet season (∼4 months post-transplant) and at the end of the experiment (∼7 months post-transplant).ResultsPatterns of seedling performance varied among species and were inconsistent over time. Significant effects of field environment were detected for two of the four species: at the end of the wet season,Virola surinamensisseedlings had higher survival beneath their maternal tree than other conspecific trees, while the opposite pattern was found inOrmosia macrocalyx.However, these differences disappeared by the end of the experiment.ConclusionsOur results suggest that intraspecific plant-soil feedbacks occur inconsistently under field conditions in tropical tree species and may have a limited role in determining seedling performance in tropical tree communities. Future studies are needed to elucidate the environmental and genetic factors that determine the incidence and direction of intraspecific plant-soil feedbacks in plant communities.

“…For instance, studies on the model species Arabidopsis thaliana showed that negative PSF effects depended on which accession had previously occupied the soil (Aguilera et al 2011; Bukowski and Petermann 2014). Differences in PSFs within species have been documented also in Plantago lanceolata (Kirchhoff et al 2019) and Trifolium pratense (Wagg et al 2015). However, studies have mainly focused on forbs, and the intraspeci c variation for plant-soil feedbacks in other plant taxonomic groups remain still unresolved.…”

Inter- and intraspecific plant-soil feedbacks of grass species

Background and aimsPlants continuously interact with soil microbiota. These plant-soil feedbacks (PSFs) are considered a driving force in plant community dynamics. However, most PSF information comes from inter-family studies, with limited information on possible causes. We studied the variation of PSFs between and within grass species and identi ed the soil microbes that are associated with the observed PSFs effects. MethodsWe grew monocultures of ten varieties of three grass species (Lolium perenne, Poa pratensis, Festuca arundinacea) using a two-phase PSF experiment. We measured plant total biomass to determine PSFs and correlated it with sequenced rhizosphere bacteria and fungi. ResultsIn the soil conditioning phase, grass species developed microbial legacies that affected the performance of other grass species in the feedback phase. We detected overall negative interspeci c PSFs. While we show that L. perenne and P. pratensis increased their performance respectively in conspeci c and heterospeci c soils, F. arundinacea was not strongly affected by the legacies of the previous plant species. Contrary to our expectation, we found no evidence for intraspeci c variation in PSFs. Bacterial taxa associated with PSFs included members of Proteobacteria, Firmicutes, Verrucomicrobia and Planctomycetes whereas fungal taxa included members of Ascomycota. ConclusionOur results suggest differences in PSF effects between grass species, but not between varieties within species. Thus, in the studied grass species, there might be limited potential for breeding on plant traits mediated by PSFs. Furthermore, we point out potential microbial candidates that might be driving the observed PSF effects that could be further explored.
