“…Other belowground interactions could also affect plant growth: in one study, removing local soil biota through soil sterilization shifted the balance of competitive interactions between two woody species (Chen et al. ), while in another, communities of soil microorganisms adapted to local soil moisture conditions ameliorated the effects of drought on plant fitness (Lau and Lennon ). Above‐ and belowground resource gradients may interact to affect seedling performance, and the effect depends on the species (Coomes and Grubb , Ibáñez and McCarthy‐Neumann ).…”

“…Belowground competition for soil water and nutrients between planted sugar maple seedlings and understory neighbors, though not controlled for in this experiment, might have been important, and experimental pairings of root competition "contests" suggests that the outcome of competition for nutrients or water may very much depend on the identity of the competitor (Armas and Pugnaire 2011). Other belowground interactions could also affect plant growth: in one study, removing local soil biota through soil sterilization shifted the balance of competitive interactions between two woody species (Chen et al 2012), while in another, communities of soil microorganisms adapted to local soil moisture conditions ameliorated the effects of drought on plant fitness (Lau and Lennon 2012). Above-and belowground resource gradients may interact to affect seedling performance, and the effect depends on the species Grubb 2000, Ibáñez andMcCarthy-Neumann 2014).…”

Plant species distributions, broadly shaped by climate, may also be constrained by other species. The degree to which biotic factors affect range limits is unclear, however, and few experimental studies have investigated both biotic and abiotic factors across and beyond a species’ range. We examined seedling survival and net growth for three years in contrasting canopy type (closed canopy vs. gap) and neighbor density (clipped vs. unclipped) environments for northern, central, and southern populations of sugar maple (Acer saccharum) representing a climate‐of‐origin gradient, experimentally planted from Arkansas, USA to Ontario, Canada at ten forested sites along a 1700‐km transect spanning beyond the species’ range. We hypothesized that each population's highest survival and growth would occur in its region of origin, with poorer performance in cooler or warmer areas. Refuting this hypothesis, seedlings of all three populations had greater growth and survival in sites increasingly warmer than their point of origin, although they did show poorer growth and survival at increasingly colder sites. We also hypothesized that maple survival and net growth near and beyond range margins are constrained primarily by cold temperature limitation in the north, where we expected neighbors to facilitate survival, and by competition in the south, where we expected to enhance survival and growth by reducing neighbor density. Results partially supported the hypothesis concerning biotic interactions: in canopy gaps, understory neighbors enhanced maple growth at the coolest sites but did not suppress growth as expected at the warmest sites. As the northern population grew and survived reasonably well beyond the northern range limit, and as all populations performed best at warmer sites, including beyond the southern range limit, there was tepid, if any, support for the hypothesis that climate regulated the northern limit and absolutely no support for the hypothesis that competition regulated the southern limit. Together, these three‐year findings with juvenile trees suggest that sugar maple range limits may instead be constrained by factors besides climate and competition, by those factors at another life stage, and/or by climate events such as heat waves, droughts, and cold snaps that occur at longer return intervals.

“…We excluded one publication (Brandt et al, 2015) and experiments from several publications (Coykendall and Houseman, 2014;Maron et al, 2016;Zuppinger-Dingley et al, 2016) from the Lekberg et al (2018) data set because of the absence of a full factorial design. We found nine additional PSF x competition publications that were not included in the Lekberg et al (2018) meta-analysis (de la Peña et al, 2010;Chen et al, 2012;Zhang et al, 2014;Chung and Rudgers, 2016;Bezemer et al, 2018;Hawkins and Crawford, 2018;Xue et al, 2018;Zhao et al, 2018;Lozano et al, 2019). Soil feedback manipulations for PSF experimental design were conducted in three ways in the included publications: (1) soil conditioned from the focal species ("home" soil) or from a heterospecific species ("away" soil) (hereafter, home-conditioned vs. away-conditioned), (2) live soil (majority of soil biota active; hereafter referred to as "active soil") or sterilized soil (majority of soil biota absent inactive; hereafter referred to as "inactive soil"), or (3) soil untreated or treated with fungicide (non-fungicide treated soil hereafter referred to as "diverse soil").…”

Predicting Plant-Soil Feedback in the Field: Meta-Analysis Reveals That Competition and Environmental Stress Differentially Influence PSF

et al. 2020

Past research on plant-soil feedbacks (PSF), largely undertaken in highly controlled greenhouse conditions, has established that plant species differentially alter abiotic and biotic soil conditions that in turn affect growth of other conspecific and heterospecific individuals in that soil. Yet, whether feedbacks under controlled greenhouse conditions reflect feedbacks in natural environments where plants are exposed to a range of abiotic and biotic pressures is still unresolved. To address how environmental context affects PSF, we conducted a meta-analysis of previously published studies that examined plant growth responses to multiple forms of competition, stress, and disturbance across various PSF methodology. We asked the following questions: (1) Can competition, stress, and disturbance alter the direction and/or strength of PSF? (2) Do particular types of competition, stress, or disturbance affect the direction and/or strength of PSF more than others? and (3) Do methods of conducting PSF research (i.e., greenhouse vs. field experiments and whether the source of soil inoculum conditioning is from the field vs. greenhouse) affect plant growth responses to PSF or competition, stress, and disturbance, or their interactions? We discovered four patterns that may be predictive of what future PSF studies conducted under more realistic conditions might reveal. First, relatively little is known about how PSF responds to environmental stress and disturbance compared to plant-plant competition. Second, specific types of competition enhanced negative effects of soil microbes on plant growth, and specific environmental stressors enhanced positive effects of soil microbes on plant growth. Third, whether PSF experiments are conducted in the field or greenhouse can change plant growth responses. And, fourth, how the soil conditioning phase is conducted can change plant growth responses. With more detail than previously shown, these results confirm that environmental context writ large can change plant growth responses in PSF Beals et al. PSF Differs With Competition, Stress experiments. These data should aid theory and predictions for conservation and restoration applications by showing the relative importance of competition, stress, and disturbance in PSF studies over time. Lastly, these data demonstrate how variation in experimental methods can alter interpretation and conclusions of PSF studies.

Competitive Capacity and Rhizosphere Mineralization of Organic Matter During Weed-Soil Microbiota Interactions

et al. 2019

The competition between weeds and crops is one of the main factors responsible for productivity losses in agricultural fields. This review aimed at presenting and discussing how the interactions between weeds and microorganisms can affect the competitive capacity of weeds and soil physicochemical properties. We also discuss how changes in the elemental stoichiometry of weeds can reflect their competitive and adaptative capacity. Although weeds are more dependent on associations with soil microorganisms than crops for growth, few studies have assessed the contribution of the soil microbiota to their competitive success in agroecosystems. When in competition, plants can change the elemental stoichiometry of their tissues in environments with varied nutrient availability. Elemental stoichiometry of plants has been particularly well studied using ecological approaches on the dynamics of weed populations in natural ecosystems, being a promising tool for understanding weed capacity to adapt to different agricultural managements. Plants control the biogeochemical cycles of carbon (C) and nitrogen (N) in the rhizosphere through a phenomenon known as the rhizosphere priming effect (RPE). Although this review has found some information in the literature that provides strong indications that the coexistence of weeds and crops may increase soil organic matter mineralization, we are not aware of studies investigating the effects of competition among these plants on RPE.
