Global species extinction rates are orders of magnitude above the background rate documented in the fossil record. However, recent data syntheses have found mixed evidence for patterns of net species loss at local spatial scales. For example, two recent data meta-analyses have found that species richness is decreasing in some locations and is increasing in others. When these trends are combined, these papers argued there has been no net change in species richness, and suggested this pattern is… 
Estimates of local biodiversity change over time stand up to scrutiny.
TLDR
New data and analyses are presented revealing fundamental flaws in a critique of two recent meta-analyses of local-scale temporal biodiversity change that raises points of uncertainty typical of all ecological studies, but does not provide an evidence-based alternative interpretation.
Biodiversity change is uncoupled from species richness trends: Consequences for conservation and monitoring
TLDR
It is shown how a set of species turnover indices provide more information content regarding temporal trends in biodiversity, as they reflect how dominance and identity shift in communities over time, and several limitations of species richness as a metric of biodiversity change are summarized.
Abundance decline in the avifauna of the European Union reveals cross‐continental similarities in biodiversity change
TLDR
This work finds significant biodiversity loss in the native avifauna of the European Union (EU) and estimates a decline of 17–19% in the overall breeding bird abundance since 1980: a loss of 560–620 million individual birds.
Meta-analysis of multidecadal biodiversity trends in Europe
TLDR
A quantitative synthesis of longterm biodiversity trends across Europe is reported, showing how, despite overall increase in biodiversity metric and stability in abundance, trends differ between regions, ecosystem types, and taxa.
Estimates of local biodiversity change over time stand up to scrutiny
TLDR
The critique raises points of uncertainty typical of all ecological studies, but it falls far short of providing an evidence-based alternative interpretation for the results, which are now supported by syntheses of hundreds of individual data sets of temporal biodiversity change.
Cross-continental analysis of coastal biodiversity change
TLDR
It is concluded that biodiversity metrics responsive to turnover provide a more accurate reflection of community change relative to conventional metrics (absolute richness or relative abundance) and are spatially broadly applicable.
The geography of biodiversity change in marine and terrestrial assemblages
TLDR
Examining spatial variation in species richness and composition change using more than 50,000 biodiversity time series from 239 studies found clear geographic variation in biodiversity change, suggesting that biodiversity change may be spatially structured.
Human activities influence the direction and magnitude of local biodiversity change over time
In recent decades, environmental drivers of community change have been associated with changes in biodiversity from local to global scales. Here we evaluate the role of anthropogenic drivers in

Assemblage Time Series Reveal Biodiversity Change but Not Systematic Loss
TLDR
This work analyzes 100 time series from biomes across Earth to ask how diversity within assemblages is changing through time and detects systematic loss of α diversity, but community composition changed systematically through time, in excess of predictions from null models.
Global meta-analysis reveals no net change in local-scale plant biodiversity over time
TLDR
No general tendency for local-scale plant species diversity to decline over the last century is found, calling into question the widespread use of ecosystem function experiments and directly contradicts the key assumption linking experimental results to ecosystem function as a motivation for biodiversity conservation in nature.
Recent Trends in Local-Scale Marine Biodiversity Reflect Community Structure and Human Impacts
Global effects of land use on local terrestrial biodiversity
TLDR
A terrestrial assemblage database of unprecedented geographic and taxonomic coverage is analysed to quantify local biodiversity responses to land use and related changes and shows that in the worst-affected habitats, pressures reduce within-sample species richness by an average of 76.5%, total abundance by 39.5% and rarefaction-based richness by 40.3%.
The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts
TLDR
A new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world is described and assessed.
The biodiversity of species and their rates of extinction, distribution, and protection
TLDR
The biodiversity of eukaryote species and their extinction rates, distributions, and protection is reviewed, and what the future rates of species extinction will be, how well protected areas will slow extinction Rates, and how the remaining gaps in knowledge might be filled are reviewed.
A meta-analysis of declines in local species richness from human disturbances
TLDR
A global meta-analysis of experimental and observational studies that report 327 measures of change in species richness between disturbed and undisturbed habitats across both terrestrial and aquatic biomes identifies critical knowledge gaps for predicting the effects of human disturbance on Earth's biomes.
Scenarios for Global Biodiversity in the 21st Century
TLDR
Scenarios consistently indicate that biodiversity will continue to decline over the 21st century, however, the range of projected changes is much broader than most studies suggest, partly because there are major opportunities to intervene through better policies, but also because of large uncertainties in projections.
Species Invasions Exceed Extinctions on Islands Worldwide: A Comparative Study of Plants and Birds
TLDR
The results suggest that species richness may be increasing at subglobal scales for many groups and that future research should address what consequences this may have on ecological processes.
Towards a unified descriptive theory for spatial ecology: predicting biodiversity patterns across spatial scales
TLDR
A framework is introduced that links the effects of aggregation, similarity decay, species richness and species abundances across scales, and allows one to draw inferences about biodiversity scaling under very general assumptions pertaining to the nature of interactions, the geographical distributions of individuals and ecological processes.
