Ecology Letters, Journal Year: 2021, Volume and Issue: 24(10), P. 2054 - 2064

Published: July 28, 2021

Abstract Livestock grazing is a major driver shaping grassland biodiversity, functioning and stability. Whether impacts on ecosystems are scale‐dependent remains unclear. Here, we conducted sheep‐grazing experiment in temperate to test effects the temporal stability of productivity across scales. We found that increased species but substantially decreased local community due reduced asynchronous dynamics among within communities. The negative effect propagated reduce at larger spatial By decreasing biodiversity both communities, biological insurance hence upscaling from communities further Our study provides first evidence for scale dependence through biodiversity. suggest ecosystem management should strive maintain scales achieve sustainability functions services.

Decoupled responses of above‐ and below‐ground stability of productivity to nitrogen addition at the local and larger spatial scale

Global Change Biology, Journal Year: 2022, Volume and Issue: 28(8), P. 2711 - 2720

Published: Jan. 30, 2022

Temporal stability of net primary productivity (NPP) is important for predicting the reliable provisioning ecosystem services under global changes. Although nitrogen (N) addition known to affect temporal aboveground (ANPP), it unclear how impacts that belowground (BNPP) and NPP, whether such effects are scale dependent. Here, using experimental N in a grassland, we found different responses ANPP BNPP at local these propagated larger spatial scale. That is, significantly decreased but did not NPP two scales investigated. Additionally, asynchrony both among communities provided greater was affected by addition. Our findings challenge traditional view would reduce based on results from dynamics, thus highlighting importance viewing whole system perspective.

Spatial asynchrony matters more than alpha stability in stabilizing ecosystem productivity in a large temperate forest region

Global Ecology and Biogeography, Journal Year: 2022, Volume and Issue: 31(6), P. 1133 - 1146

Abstract Aim Understanding the biodiversity–stability relationship has become a central issue in ecology and conservation biology. Although stabilizing effects of tree species diversity on ecosystem productivity are well recorded small local communities, they remain poorly understood across scales (from to larger spatial scales). This study evaluates from large temperate forest region, considering range environmental conditions heterogeneity. Location North‐eastern China ( c . 700,000 km 2 ). Time period 2005–2017. Major taxa studied Woody plants. Methods We define stability as temporal invariability biomass productivity. Regional metacommunities representing were developed by aggregating multiple sets field plots. Simple regression analysis was used test relationships metacommunities. Piecewise structural equation modelling then disentangle abiotic variables at scales. Multiple mixed‐effects models determine relative contribution individual predictive Results found that (alpha diversity) positively related communities stability), whereas turnover space (beta asynchronous dynamics among (spatial asynchrony), regardless whether factors considered or not. also heterogeneity affected The effect asynchrony gamma greater than alpha stability. Main conclusions Our results imply is key maintaining within region. suggest diverse forests heterogeneous landscapes should be sustained buffer negative climate change degradation.

Soil biota diversity and plant diversity both contributed to ecosystem stability in grasslands

Understanding the effects of diversity on ecosystem stability in context global change has become an important goal recent ecological research. However, at multiple scales and trophic levels across environmental gradients remain unclear. Here, we conducted a field survey α-, β-, γ-diversity plants soil biota (bacteria, fungi, nematodes) estimated temporal normalized difference vegetation index (NDVI) 132 plots Mongolian Plateau. After climate variables were controlled for, both α- β-diversity (mainly via together with precipitation explained most variation stability.

Latitudinal patterns of forest ecosystem stability across spatial scales as affected by biodiversity and environmental heterogeneity

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(8), P. 2242 - 2255

Published: Jan. 11, 2023

Our planet is facing a variety of serious threats from climate change that are unfolding unevenly across the globe. Uncovering spatial patterns ecosystem stability important for predicting responses ecological processes and biodiversity to change. However, understanding latitudinal pattern scales underlying drivers still very limited. Accordingly, this study examines at local regional scale using natural assembly forest metacommunities distributed over large temperate region, considering range potential environmental drivers. We found communities (regional stability) asynchronous dynamics among (spatial asynchrony) both decreased with increasing latitude, whereas (local did not. tested series hypotheses potentially drive stability, although biodiversity, climatic history, resource conditions, heterogeneity varied multiple were affected by heterogeneity. In particular, α diversity positively associated while β asynchrony, relationships weak. provides first evidence temporal naturally assembled driven findings suggest preservation plant within between maintenance heterogeneous landscapes can be crucial buffer ecosystems higher latitudes faster more intense negative impacts in future.

Landscape perspectives for agroecological weed management. A review

Agronomy for Sustainable Development, Journal Year: 2024, Volume and Issue: 44(1)

Abstract Faced with the biodiversity extinction crisis and climate change, alternative approaches to food production are urgently needed. Decades of chemical-based weed control have resulted in a dramatic decline diversity, negative repercussions for agroecosystem biodiversity. The simplification cropping systems evolution herbicide resistance led dominance small number competitive species, calling more sustainable approach that considers not only abundance but also community diversity composition. Agroecological management involves harnessing ecological processes minimize impacts weeds on productivity maximize However, current research effort agroecological is largely rooted agronomy field-scale farming practices. In contrast, contributions landscape-scale interventions unexplored (e.g., promote pollinators natural enemies or carbon sequestration). Here, we review knowledge landscape effects properties (abundance, composition) seed predation (a key factor management). Furthermore, discuss underlying effects, their interaction in-field approaches, implications change management. Notably, found (1) context rarely affects total abundance; (2) configurational than compositional heterogeneity landscapes associated higher alpha, beta, gamma diversity; (3) evidence currently limited; (4) plant spillover from neighboring habitats most common interpretation properties, whereas many other overlooked. Strikingly, drivers biological regulation at scale remain poorly understood. We recommend addressing these issues better integrate into management, which could inform movement towards managing farms wider spatiotemporal scales single fields season.

Biotic and Abiotic Drivers of Ecosystem Temporal Stability in Herbaceous Wetlands in China

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(1)

Published: Jan. 1, 2025

ABSTRACT Maintaining the stability of ecosystems is critical for supporting essential ecosystem services over time. However, our understanding contribution diverse biotic and abiotic factors to this in wetlands remains limited. Here, we combined data from a field vegetation survey 725 herbaceous wetland sites China with remote sensing information Enhanced Vegetation Index (EVI) 2010 2020 explore temporal primary productivity. We found that plant species richness directly contributed on national scale, but differed among climate zones, hydrological regimes, types. In addition, many factors, including soil properties, geographical location, also stability. Piecewise structural equation modeling identified pH, total nitrogen, organic carbon, emerged as modulating stability, both indirectly by affecting type. Higher carbon were related higher peatlands less so coastal inland marshes. These findings enhance ability forecast how may respond future environmental changes biodiversity loss can inform policy decisions
