Abstract Plant–fungal associations strongly influence forest carbon and nitrogen cycling. The prevailing framework for understanding these relationships is through the relative abundance of arbuscular (AM) versus ectomycorrhizal (EcM) trees. Ericoid mycorrhizal (ErM) shrubs are also common in forests interactions between co‐occurring ErM AM EcM trees could shift soil biogeochemical responses. Here we test hypotheses that effects on either extend or redundant with those Using regional...
Tree mycorrhizal type is increasingly recognised as a key determinant of the quantity and quality soil carbon stocks from local to global scales. However, direct evidence linking associations age persistence pools remains lacking. Here, we leverage radiocarbon (14C) analysis investigate mean particulate organic (POC) mineral-associated (MAOC) fractions across temperate forests dominated by arbuscular (AM) or ectomycorrhizal (EcM) tree species. Our findings reveal significant interactions...
Slash walls are a novel strategy that could help maintain species on sites where ungulate browse limits tree regeneration. We established five slash in southern New England, USA to examine the influence of pre-harvest metrics and deer exclusion stump sprout height survival at 160 sample points (n=1,509 trees). For all groups, dominant sprouts were taller inside end first second growing seasons. After two years, mean heights ~2.5-times higher for Quercus rubra (1.8 vs. 0.7 m) >6-times Acer...
Abstract Animals interact with and impact ecosystem biogeochemical cycling—processes known as zoogeochemistry. While the deposition of various animal materials (e.g. carcasses faeces) has been shown to create nutrient hotspots alter cycling storage, inputs from parturition (i.e. calving) have yet be explored. We examine effects ungulate parturition, which often occurs synchronously during spring green‐up therefore aligns increased plant nitrogen demand in temperate biomes. Impacts...
Abstract As urbanization increases worldwide, investments in nature‐based solutions that aim to mitigate urban stressors and counter the impacts of global climate change are also on rise. Tree planting degraded lands—or afforestation—is one form solution has been increasingly implemented cities around world. The benefits afforestation are, however, contingent capacity soils support growth planted trees, which poses a challenge some settings where unfavorable soil conditions limit tree...
Abstract Plant mycorrhizal associations influence the accumulation and persistence of soil organic matter could therefore shape ecosystem biogeochemical responses to global changes that are altering forest composition. For instance, arbuscular (AM) tree dominance is increasing in temperate forests, ericoid (ErM) shrubs can respond positively canopy disturbances. Yet how shifts co‐occurrence trees with different will affect pools remains largely unknown. We examine effects ErM on carbon...
Differences between arbuscular (AM) and ectomycorrhizal (EcM) trees strongly influence forest ecosystem processes, in part through their impact on saprotrophic fungal communities. Ericoid mycorrhizal (ErM) shrubs likely also communities given that they can shape nutrient cycling by slowing decomposition rates intensifying nitrogen limitation. We investigated the depth distributions of EcM paired subplots with without a common understory ErM shrub, mountain laurel (Kalmia latifolia L.),...
Abstract Managing for structural complexity to enhance forest ecosystem health and resiliency is increasingly incorporated in silvicultural treatments. High spatial variability stands managed could obscure the effects of management on surface soils. Yet few studies have assessed how within-stand variation structure other local controls influence soil organic matter dynamics over time following timber harvests. We used a stratified random sampling design capture stand age, legacy structure,...
ABSTRACT Anthropogenic nitrogen (N) deposition is unequally distributed across space and time, with inputs to terrestrial ecosystems impacted by industry regulations variations in human activity. Soil carbon (C) content normally controls the fraction of mineralized N that nitrified ( ƒ ), affecting bioavailability for plants microbes. However, it unknown whether has modified relationships among soil C, net mineralization, nitrification. To test alters relationship between C transformations,...
Abstract Background and Aims In closed-canopy, mature forests, tree shrub mycorrhizal associations are important controls on soil nitrogen availability. Whether these plant-fungal effects observed in forests at earlier successional stages, following disturbances such as harvests or windstorms, is largely unexplored. We quantify how versus influence cycling explore the potential for known underlying mechanisms, availability of carbon, to explain patterns we observe. Methods measure net N...
