“…As an example, changes in soil chemistry driven by conifers documented in this study have been shown to have stronger negative effects on primary metabolism, growth, and defense of establishing aspen than fir seedlings [57]. Furthermore, light limitation imposed by conifer expansion also constrains symbiotic mycorrhizal associations on aspen roots that can further limit their acquisition of soil nutrients [58]. Changes in disturbance regimes or climate scenarios that favor conifer expansion or loss of aspen are likely to decrease soil resource availability, with strong potential feedbacks on plant community development.…”

Development and change in forest communities are strongly influenced by plant-soil interactions. The primary objective of this paper was to identify how forest soil characteristics vary along gradients of forest community composition in aspen-conifer forests to better understand the relationship between forest vegetation characteristics and soil processes. The study was conducted on the Fishlake National Forest, Utah, USA. Soil measurements were collected in adjacent forest stands that were characterized as aspen dominated, mixed, conifer dominated or open meadow, which includes the range of vegetation conditions that exist in seral aspen forests. Soil chemistry, moisture content, respiration, and temperature were measured. There was a consistent trend in which aspen stands demonstrated higher mean soil nutrient concentrations than mixed and conifer dominated stands and meadows. Specifically, total N, NO3 and NH4 were nearly two-fold higher in soil underneath aspen dominated stands. Soil moisture was significantly higher in aspen stands and meadows in early summer but converged to similar levels as those found in mixed and conifer dominated stands in late summer. Soil respiration was significantly higher in aspen stands than conifer stands or meadows throughout the summer. These results suggest that changes in disturbance regimes or climate scenarios that favor conifer expansion or loss of aspen will decrease soil resource availability, which is likely to have important feedbacks on plant community development.

“…In conquering the land, plants have sculpted the biosphere and geosphere through their influence on global carbon, nutrient, and water cycles [1], leading to the development of climates and habitats that are essential for supporting the diverse array of life that now exists in terrestrial environments [2,3]. It is estimated that more than 80% of living plant species form symbioses (see Glossary) with horizontally transmitted filamentous fungi, representing 92% of plant families worldwide [4] (Figure 1).…”

“…Nonvascular plants are still major contributors to global nitrogen and carbon cycling [38]. Some of the first plants to emerge onto land were morphologically similar to modern-day liverworts [3,39], while others were unlike any extant species (Figure 1). Given that nonvascular plants are the closest living relatives of the first land plants [40,41], they are the most appropriate organisms for inferring experimentally the ecology and evolution of partnerships between early land plants and fungi.…”

19We reconsider the existing paradigm and show that the symbiotic options available to 20 the first plants emerging onto the land were more varied than previously thought. 22The current paradigm 23 The colonisation of the terrestrial environment by plants was a major turning point in Earth's carbohydrates fixed from atmospheric carbon dioxide through photosynthesis [5]. 35Plant life diversified on land some 70 MY after the diversification of most major 36 animal lineages in the seas during the Cambrian explosion ( Fig. 1) [6]. Classic palaeoclimate 37 3 modelling shows that land plants diversified against a backdrop of falling atmospheric CO 2 38[7] (Figure 2), likely driven by growing demand and evolving capacity for carbon 39 assimilation of the burgeoning Earth flora [8,9]. Long before land plants emerged, however, 40 the terrestrial environment had been colonised by fungi [10,11]. Among the early-branching 41 fungal lineages were those that today form mutualistic associations with most plants (Figure 42 1). The macrofossil record for non-vascular plants is even more fragmentary than that for 43 vascular plants, though the study of microfossils is now providing key new data [12,13] lineages of land plants [24,25]. 60The resulting paradigm is that the earliest, rootless, terrestrial plants co-evolved with 61Glomeromycota fungi [4,[26][27][28][29][30] 153We now know that liverwort-Glomeromycota symbioses can be mutualistic, involving fungi within plant tissues. An alternative but untested hypothesis is that their evolution was 287 linked to harbouring an overlooked or extinct microbial symbiont of green algae [22]. 288The assumption that function of mycorrhizal and mycorrhiza-like fungal associations 289 is also conserved across land plant evolution has, until recently, been based on striking However, while we know for instance that functioning in modern vascular plant-
