Rapid, extensive, and ongoing environmental change increasingly demands that humans intervene in ecosystems to maintain or restore ecosystem services biodiversity. At the same time, basic principles tenets of restoration ecology conservation biology are being debated reshaped. Escalating global is resulting widespread no-analogue environments novel render traditional goals unachievable. Policymakers general public, however, have embraced without an understanding its limitations, which has...
Climate gradients shape spatial variation in the richness and composition of plant communities. Given future predicted changes climate means variability, likely regional magnitudes these changes, it is important to determine how temporal influences community structure. Here, we evaluated species richness, turnover, grassland communities responded interannual precipitation by synthesizing long-term data from grasslands across United States. We found that mean annual precipitation,(MAP) was a...
Summary New analytical tools applied to long‐term data demonstrate that ecological communities are highly dynamic over time. We developed an r package, library(“codyn”) , help ecologists easily implement these metrics and gain broader insights into community dynamics. provides temporal diversity indices stability metrics. All functions designed be implemented multiple replicates. Temporal include species turnover, mean rank shifts rate of change Community calculate overall patterns...
Understanding how biotic mechanisms confer stability in variable environments is a fundamental quest ecology, and one that becoming increasingly urgent with global change. Several mechanisms, notably portfolio effect associated species richness, compensatory dynamics generated by negative covariance selection for stable dominant populations can increase the of overall community. While importance these debated, few studies have contrasted their an environmental context. We analyzed nine...
Significance Accurate prediction of community responses to global change drivers (GCDs) is critical given the effects biodiversity on ecosystem services. There consensus that human activities are driving species extinctions at scale, but debate remains over whether GCDs systematically altering local communities worldwide. Across 105 experiments included 400 experimental manipulations, we found evidence for a lagged response herbaceous plant caused by shifts in identities and relative...
Abstract Aim Biologists increasingly recognize the roles of humans in ecosystems. Subsequently, many have argued that biodiversity conservation must be extended to environments shaped directly. Yet popular biogeographical frameworks such as biomes do not incorporate human land use, limiting their relevance future planning. ‘Anthromes’ map global ecological patterns created by sustained direct interactions with In this paper, we set understand how current efforts are distributed across...
Understanding stability across ecological hierarchies is critical for landscape management in a changing world. Recent studies showed that synchrony among lower‐level components key to scaling temporal two hierarchical levels, whether spatial or organizational. But an extended framework integrates both scale and organizational level simultaneously required clarify the sources of ecosystem at large scales. However, such extension far from trivial when taking into account heterogeneities...
Abstract Over the last decade, several research and opinion pieces have challenged tenets of restoration ecology but a lack centralized data has impeded assessment how scientific developments relate to on‐the‐ground restoration. In response, Society for Ecological Restoration ( SER ) launched Global Network GRN catalog worldwide efforts. We reviewed over 200 projects identify goals governing frequency with which they are measured. used Primer on frame our analysis, categorizing by 's...
Abstract Univariate and multivariate methods are commonly used to explore the spatial temporal dynamics of ecological communities, but each has limitations, including oversimplification or abstraction communities. Rank abundance curves (RACs) potentially integrate these existing methodologies by detailing species‐level community changes. Here, we had three goals: first, simplify analysis developing a coordinated set R functions, second, demystify relationships among univariate, multivariate,...
Summary Rainfall is a key determinant of production and composition in arid semi‐arid systems. Long‐term studies relating water availability primarily focus on current‐year precipitation patterns, though mounting evidence highlights the importance previous‐year rainfall particularly grasslands dominated by perennial species. The extent to which lagged effects occur annual grasslands, however, remains largely unexplored. We pair long‐term study with two manipulative experiments identify...
Abstract Heterogeneity is increasingly recognized as a foundational characteristic of ecological systems. Under global change, understanding temporal community heterogeneity necessary for predicting the stability ecosystem functions and services. Indeed, spatial commonly used in alternative stable state theory predictor therefore an early indicator regime shifts. To evaluate whether species composition predictive communities, we analyzed 68 data sets spanning freshwater terrestrial systems...
Abstract Modelling species interactions in diverse communities traditionally requires a prohibitively large number of species‐interaction coefficients, especially when considering environmental dependence parameters. We implemented Bayesian variable selection via sparsity‐inducing priors on non‐linear abundance models to determine which should be retained and can represented as an average heterospecific interaction term, reducing the model evaluated performance using simulated communities,...
Abstract Analysing temporal patterns in plant communities is extremely important to quantify the extent and consequences of ecological changes, especially considering current biodiversity crisis. Long‐term data collected through regular sampling permanent plots represent most accurate resource study succession, analyse stability a community over time understand mechanisms driving vegetation change. We hereby present LOng‐Term Vegetation Sampling (LOTVS) initiative, global collection...
1. Annual above-ground net primary productivity (ANPP) in mesic grasslands is known to be highly temporally variable. While yearly precipitation or average temperature can explain some of this temporal variability, much the variation ANPP remains unexplained. 2. Here we address heretofore unexplained 25 years data from a grassland at Konza Prairie (north-eastern Kansas) by examining effects and during periods relevant phenology growth cycle dominant C4 grasses flowering stalk production...
