Nutrients and herbivores are well-known drivers of grassland diversity stability in local communities. However, whether they interact to impact the aboveground biomass these effects depend on spatial scales remain unknown. It is also unclear nutrients via different facets plant including species richness, evenness, changes community composition through time space. We used a replicated experiment adding excluding for 5 years 34 global grasslands explore questions. found that both nutrient...
Abstract Eutrophication usually impacts grassland biodiversity, community composition, and biomass production, but its impact on the stability of these aspects is unclear. One challenge that has many facets can be tightly correlated (low dimensionality) or highly disparate (high dimensionality). Using standardized experiments in 55 sites from a globally distributed experiment (NutNet), we quantify effects nutrient addition five (temporal invariability, resistance during dry wet growing...
Abstract Declines in grassland diversity response to nutrient addition are a general consequence of global change. This decline species richness may be driven by multiple underlying processes operating at different time‐scales. Nutrient can reduce enhancing the rate local extinction via competitive exclusion, or reducing colonization constraining pool able colonize under new conditions. Partitioning net change into and rates will better delineate long‐term effect grasslands. We synthesized...
Abstract Dominance often indicates one or a few species being best suited for resource capture and retention in given environment. Press perturbations that change availability of limiting resources can restructure competitive hierarchies, allowing new to retain leaving once dominant fated decline. However, may maintain high abundances even when their environments no longer favour them due stochastic processes associated with abundance, impeding deterministic would otherwise diminish them....
Abstract Land abandonment has been increasing in recent decades Europe, usually accompanied by biodiversity decline. Whether livestock grazing and mowing can safeguard across spatial scales the long term is unclear. Using a 48‐year experiment salt marsh, we compared land (without mowing) seven management regimes including cattle grazing, early season mowing, late both plus each of on plant diversity at local larger (i.e. aggregated communities). Also, their effects community composition...
A number of continuous eddy covariance measurements and long-term biomass inventories had proved that old-growth forests are carbon sinks worldwide. The present study estimated the net ecosystem productivity (NEP) for an subtropical forest at Dinghushan Biosphere Reserve in South China to investigate temporal pattern sequestration, both seasonally annually. measured NEP over 7 years (from 2003 2009) showed this was a sink, ranging from 230 (in 2008) 489…−2 year−1 2004). greatest value found...
In this study, tundra N 2 O and CH 4 fluxes were measured from one seabird sanctuary (SBT) two non‐seabird colonies (NST‐I NST‐II) in Ny‐Ålesund (79°55′N, 11°56′E), Svalbard during the summers of 2008 2009. SBT showed large temporal spatial variations depending on intensity activity. High activity sites emissions while low emissions, even uptake occurred at medium sites. Overall mean 18.3 ± 3.6 μ g m −2 h −1 53.5 20.3 whereas NST‐I NST‐II represented a relatively weak source (8.3 13.2 )...
Abstract The long‐term influence of persistent small herbivores on successional plant community configuration is rarely studied. We used a herbivore exclusion experiment along the gradient in salt‐marsh system, to investigate effects hares and geese, alone, diversity at five stages (the earliest, two early, intermediate late stages) short long term, i.e. 7 22 years, respectively. Plant declined over time all except for earliest one. Small slowed down species decline, but only one early...
Abstract Nutrient enrichment impacts grassland plant diversity such as species richness, functional trait composition and diversity, but whether how these changes affect ecosystem stability in the face of increasing climate extremes remains largely unknown. We quantified direct diversity‐mediated effects nutrient addition (by nitrogen, phosphorus, potassium) on above‐ground biomass production 10 long‐term experimental sites. measured five facets temporal invariability, resistance during...
Abstract Human activities are altering ecological communities around the globe. Understanding implications of these changes requires that we consider composition those communities. However, can be summarized by many metrics which in turn influenced different processes. For example, incidence‐based strongly reflect species gains or losses, while abundance‐based minimally affected abundance small uncommon species. Furthermore, might correlated with predictors. We used a globally distributed...
The mechanism of immobilization heavy metals in the soil using biochar has been studied extensively. However, decomposition by biological and abiotic factors can reactivate immobilized soil. Previous research showed that addition calcium carbonate (bio-CaCO3) significantly increase stability biochar. influence bio-CaCO3 on ability to immobilize remains unclear. Therefore, this study evaluated effect use cationic metal lead anionic antimony. not only improved passivation Pb Sb but also...
Abstract Evaluation of long-term management regimes is important for guiding biodiversity conservation in salt marshes. However, such experiments are sparse. Using a 46-year experiment marsh, we evaluated effects eight different (treatments; control, grazing, mowing, and their combinations) on the expansion late successional plant species ( Elytrigia atherica ), richness diversity, community composition (species identities dominance structure). Results show that E. expanded strongly over...
Plant adaptation to sea level rise has important implications for conservation and shoreline protection. However, it received much less attention than other global changes. Here I explored of one the dominant plants in European saltmarshes whether this is mediated by successional stages. Different stages have distinct characteristics such as nutrient availability. collected Elytrigia atherica from high low marsh at early, intermediate, late E. samples were randomly assigned two groups, group...
The effects of pressure, feed rate, and abrasive mass flow rate on surface roughness were investigated during water cutting recombinant bamboo. Two different thicknesses (10 mm 15 mm) bamboo cut in the longitudinal transversal directions by jet. All experiments arranged using response methodology. parameter Ra was selected to represent roughness. value increased with an increase but decreased pressure. lower when fiber longitudinally than transversally.
Soil Moisture (SM) is an important parameter to describe water cycle, land condition and soil biology. The spatial resolution of SM data acquired by satellites remote sensing relatively low, so downscaling techniques are used obtain high-resolution meet practice demand. However, there few algorithm for in complex terrain areas. Temperature Vegetation Drought Index (TVDI) intermediate variable between Normalized (NDVI) Land Surface (LST) TDVI expected retrieve precisely. This study applies...
The small-and medium-sized rivers are affected by the perennial dry flow. historical water level is scarce, which cannot meet number of training samples in neural network modeling. model's accuracy requirements when using traditional machine learning methods to predict level. An intelligent prediction model for based on small sample data proposed solve this problem. primary established Bayesian linear regression, and k-nearest neighbor algorithm introduced achieve first correction results....
Abstract The positive effects of large herbivores on plant diversity in grasslands have so far been mainly attributed to increased light availability or suppressed dominance, and thus the consequences aboveground biomass consumption (trophic effects). However, these insights are derived from short-term experiments. Using a 46-year experiment salt marsh, comparing cattle grazing, mowing (as proxy consumption) ungrazed control, we found that non-trophic (e.g. trampling, deposition urine dung)...
Abstract Nutrient enrichment typically causes local plant diversity decline. A common but untested expectation is that it reduces variation in nutrient conditions among localities and selects for a smaller pool of species, causing greater declines at larger scales biotic homogenization. We apply topology linking changes species richness across characterizes the numbers spatially restricted widespread to standardized experiment adding nutrients 72 grasslands on six continents. Overall, we...
