Recent analyses have reported catastrophic global declines in vertebrate populations1,2. However, the distillation of many trends into a global mean index obscures the variation that can inform conservation measures and can be sensitive to analytical decisions. For example, previous analyses have estimated a mean vertebrate decline of more than 50% since 1970 (Living Planet Index2). Here we show, however, that this estimate is driven by less than 3% of vertebrate populations; if these extremely… Expand
Insect decline in the Anthropocene: Death by a thousand cuts
The entomological community was in need of a thorough review and the annual meeting provided a timely opportunity for sharing information, and the goal of the symposium was to assemble world experts on insect biodiversity and conservation and ask them to report on the state of knowledge of insect population trends.

Habitat change and biased sampling influence estimation of diversity trends
Analysis of standardized routes from the North American Breeding Bird Survey shows that major local habitat change is associated with an increase in the rate of survey cessations, and implies that biodiversity loss can be underestimated by biases introduced if continued sampling in longitudinal studies is influenced by local change. Expand
Random population fluctuations bias the Living Planet Index.
It is shown how random fluctuations lead to a declining LPI even when overall population trends are stable and imprecise estimates of the LPI when populations increase or decrease nonlinearly. Expand
Life-history predicts global population responses to the weather in the terrestrial mammals
Overall, there was no consistent effect of temperature or precipitation anomalies on annual population growth rates, but there was variability in weather responses for populations within a species, and long-lived mammals with smaller litter sizes had responses with a reduced absolute magnitude compared to their shorter-living counterparts with larger litters.

Annual changes in the Biodiversity Intactness Index in tropical and subtropical forest biomes, 2001–2012
The Biodiversity Intactness Index (BII) fell by an average of 1.9 percentage points between 2001 and 2012, with 81 countries seeing an average reduction and 43 an average increase; the extent of primary forest fell by 3.9% over the same period. Expand
Accounting for year effects and sampling error in temporal analyses of invertebrate population and biodiversity change: a comment on Seibold et al. 2019
An accumulating number of studies are reporting severe insect declines. These studies aim to quantify temporal changes in invertebrate populations and community composition and attribute them toExpand
Local biodiversity change reflects interactions among changing abundance, evenness and richness
Interdependencies found here suggest looking beyond changes in abundance, evenness and richness as separate responses offering unique insights into diversity change can increase the understanding of biodiversity change. Expand
No pervasive size trend in global community dynamics
There is no pervasive tendency across biomes for larger species to be doing proportionally better or worse than smaller species, and within communities there is no clear trend between size traits and changes in abundance rank over time. Expand
The agglomeration and dispersion dichotomy of human settlements on Earth
Human settlements on Earth are scattered in a multitude of shapes, sizes and spatial arrangements. These patterns are often not random but a result of complex geographical, cultural, economic andExpand
Underestimating the Challenges of Avoiding a Ghastly Future
We report three major and confronting environmental issues that have received little attention and require urgent action. First, we review the evidence that future environmental conditions will beExpand


Trends in mean growth and stability in temperate vertebrate populations
Mean trends for amphibians suggested a systematic decline, whereas birds, reptiles and mammals were increasing, on average, and freshwater fishes showed no net change in general, which suggests populations are generally becoming more unstable, even in temperate, developed nations, with arguably the strongest environmental regulations. Expand
Decline of the North American avifauna
Using multiple and independent monitoring networks, population losses across much of the North American avifauna over 48 years are reported, including once-common species and from most biomes, demonstrating a continuing avifaunal crisis. Expand
All is not decline across global vertebrate populations
Abstract The populations of Earth’s species are changing over time in complex ways, creating a mixture of winners and losers in a time of accelerating global change. A critical research challenge isExpand
A balance of winners and losers in the Anthropocene.
For a set of 23 241 populations, 16 009 species, in 158 assemblages, significantly accelerating extinction and colonisation rates were detected, with both rates being approximately balanced. Expand
Monitoring change in vertebrate abundance: the living planet index.
The task of measuring the decline of global biodiversity and instituting changes to halt and reverse this downturn has been taken up in response to the Convention on Biological Diversity's 2010Expand
The Diversity-Weighted Living Planet Index: Controlling for Taxonomic Bias in a Global Biodiversity Indicator
This report reports on an approach to tackle taxonomic and geographic bias in one such indicator (Living Planet Index) by accounting for the estimated number of species within biogeographical realms, and the relative diversity of species inside them, and estimates a global population decline in vertebrate species between 1970 and 2012.

Worldwide decline of the entomofauna: A review of its drivers
Abstract Biodiversity of insects is threatened worldwide. Here, we present a comprehensive review of 73 historical reports of insect declines from across the globe, and systematically assess theExpand
Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines
The population extinction pulse shows, from a quantitative viewpoint, that Earth’s sixth mass extinction is more severe than perceived when looking exclusively at species extinctions and humanity needs to address anthropogenic population extirpation and decimation immediately. Expand
Hotspots of human impact on threatened terrestrial vertebrates
It is shown that impacts to species are widespread, occurring across 84% of Earth’s surface, and hotspots of impacted species richness and coolspots of unimpacted species richness are identified, providing essential information for future national and global conservation agendas. Expand
The geography of biodiversity change in marine and terrestrial assemblages
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. Expand
