Soil organic carbon (SOC) is primarily formed from plant inputs, but the relative (C) contributions living root inputs (i.e. rhizodeposits) vs litter + shoot litter) are poorly understood. Recent theory suggests that exert a disproportionate influence on SOC formation, few field studies have explicitly tested this by separately tracking as they move through soil food web and into distinct pools. We used manipulative experiment with an annual C4 grass in forest understory to differentially...
Determining the drivers of non-native plant invasions is critical for managing native ecosystems and limiting spread invasive species1,2. Tree in particular have been relatively overlooked, even though they potential to transform economies3,4. Here, leveraging global tree databases5-7, we explore how phylogenetic functional diversity communities, human pressure environment influence establishment species subsequent invasion severity. We find that anthropogenic factors are key predicting...
Abstract Managing invasive species is a current challenge for biodiversity conservation. A recurring recent suggestion that by harvesting nonnatives human consumption, people can control populations. Even though humans may be able to or eradicate certain populations of nonnative them as food sources, several caveats should considered before starting these programs. prominent problem creating market engenders pressure maintain problematic species. Also, if the target becomes an economic...
A central challenge in plant ecology is to define the major axes of functional variation with direct consequences for fitness. Central three main components fitness (growth, survival, and reproduction) rate metabolic conversion CO2 into carbon that can be allocated various structures functions. Here we (1) argue a primary constraint on maximum photosynthesis per unit leaf area size packing density cells (2) show genome strong predictor cell sizes, densities, across terrestrial vascular...
Abstract Temperate understory plant species are at risk from climate change and anthropogenic threats that include increased deer herbivory, habitat loss, pollinator declines mismatch, nutrient pollution. Recent work suggests spring ephemeral wildflowers may be additional due to phenological mismatch with deciduous canopy trees. The study of this dynamic, commonly referred as “phenological escape”, its sensitivity temperature is limited eastern North America. Here, we use herbarium specimens...
Policymakers and businesses in Southeast Asia are increasingly interested using carbon markets to encourage adoption of regenerative agriculture practices by farmers. These thought mitigate climate change reducing soil loss enhancing sequestration. However, there is uncertainty the ability increase organic (SOC) stocks croplands. We reviewed 92 empirical studies that investigated effects 17 farming across 11 broad categories crops on SOC stock or content Asia. Our synthesis found supporting...
Shifting community assembly dynamics are an underappreciated mechanism by which warming will alter plant composition. Germination timing (which can determine the order in seedlings emerge within a community) likely shift unevenly across species response to warming. In seasonal environments where communities reassemble at beginning of each growing season, changes germination could lead priority effects, and ultimately We test this expectation assembling mesocosms 15 one two orders-"ambient"...
Summary Though co‐occurrence of invasive plant species is common, few studies have compared the community and ecosystem impacts invaders when they occur alone co‐occur. Prioritization management efforts requires sufficient knowledge – both among individual different sets co‐occurring to target resources towards sites expected undergo largest change. Here, we observed differences in above‐ below‐ground two woody shrubs, L onicera maackii igustrum sinense , plots containing shrubs (mixed),...
Abstract Long‐term research in ecology and evolution ( LTREE ) is considered fundamental for understanding complex ecological evolutionary dynamics. However, others have argued revision of efforts given perceived limitations current priorities approaches. Yet most arguments about the benefits failings could be to reflect views only limited number scientists who authored reports on field, not wider community scientists. To more systematically quantitatively assess contributions future...
Abstract Functional diversity ( FD ) metrics are widely used to assess invasion ecosystem impacts, but we have limited theory predict how should respond invasion. A key challenge effectively using is the complexity of conceptualizing alterations multidimensional trait space, making it difficult select a priori most appropriate metric for specific ecological questions. Here, provide expectations on change four commonly metrics—functional richness (F Ric ), evenness Eve divergence Div and...
Although the co-occurrence of nonnative vertebrates is a ubiquitous global phenomenon, study interactions between invaders poorly represented in literature. Limited understanding co-occurring can be problematic for predicting how removal only one invasive—a common management scenario—will affect native communities. We suggest trophic food web framework effects single-species on biodiversity. used literature search and meta-analysis to assess current invasive vertebrate affects biodiversity...
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...
Most biological invasion literature—including syntheses and meta-analyses the resulting theory—is reported from temperate regions, drawing only minimally tropics except for some island systems. The lack of attention to invasions in results reinforces assumption that tropical ecosystems, especially continental tropics, are more resistant invasions. We have critically assessed compared them with finding relatively weak evidence regions differ their invasibility traits determine invader success...
The coronavirus pandemic is more fully exposing ubiquitous economic and social inequities that pervade conservation science. In this time of prolonged stress on members the research community, primary investigators or project leaders (PLs) have a unique opportunity to adapt their programs jointly create equitable productive environments for teams. Institutional guidance PLs pursuing field laboratory work centers physical safety individuals while in lab field, but largely ignores vast...
Abstract Deciduous trees, shrubs and forest wildflowers may be advancing their leaf‐out phenology at different rates in response to a warming climate. A mismatch between understory overstory lead reduction of light levels the early spring, which is critical period when many spring‐blooming achieve highest photosynthetic rates. However, extent this phenomenon beyond single site or region largely unknown. Using 3083 herbarium specimens collected 1870 2019 across eastern North America, we...
There is disagreement about the potential for regenerative management practices to sequester sufficient soil organic carbon (SOC) help mitigate climate change. Measuring change in SOC stocks following practice adoption at grain of farm fields, within extent regional agriculture, could resolve this disagreement. Yet sampling demands quantify are considered infeasible primarily because within-field variation stock sizes thought obscure accurate quantification effects on incremental accrual. We...
Abstract Communities worldwide are losing multiple species at an unprecedented rate, but how communities reassemble after these losses is often open question. It well established that the order and timing of arrival during community assembly shapes forthcoming composition function. Yet, whether can lead to divergent trajectories remains largely unexplored. Here, we propose a novel framework sets testable hypotheses on effects losses— inverse priority —and suggests its integration into study...
