The extent to which biodiversity change in local assemblages contributes global loss is poorly understood. We analyzed 100 time series from biomes across Earth ask how diversity within changing through time. quantified patterns of temporal α diversity, measured as and β community composition. Contrary our expectations, we did not detect systematic diversity. However, composition changed systematically time, excess predictions null models. Heterogeneous rates environmental change, species...
Spatial structure of species change Biodiversity is undergoing rapid driven by climate and other human influences. Blowes et al. analyze the global patterns in temporal biodiversity using a large quantity time-series data from different regions (see Perspective Eriksson Hillebrand). Their findings reveal clear spatial richness composition change, where marine taxa exhibit highest rates change. The tropics, particular, emerge as hotspots losses. Given that activities are affecting magnitudes...
The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These enable users to calculate temporal trends biodiversity within amongst using a broad range of metrics. is being developed as community-led open-source time series. Our goal accelerate facilitate quantitative analysis patterns the Anthropocene.The 8,777,413 abundance records, from consistently sampled for minimum 2 years, which need not necessarily be consecutive. In...
Abstract Climate change and other anthropogenic drivers of biodiversity are unequally distributed across the world. Overlap in distributions different have important implications for attribution potential interactive effects. However, spatial relationships among whether they differ between terrestrial marine realm has yet to be examined. We compiled global gridded datasets on climate change, land‐use, resource exploitation, pollution, alien species human population density. used multivariate...
Humans have elevated global extinction rates and thus lowered scale species richness. However, there is no a priori reason to expect that losses of richness should always, or even often, trickle down at regional local scales, though this relationship often assumed. Here, we show can modulate our estimates change through time in the face anthropogenic pressures, but not unidirectional way. Instead, magnitude increase, decrease, reverse, be unimodal across spatial scales. Using several case...
Abstract The role human activities play in reshaping biodiversity is increasingly apparent terrestrial ecosystems. However, the responses of entire marine assemblages are not well-understood, part, because few monitoring programs incorporate both spatial and temporal replication. Here, we analyse an exceptionally comprehensive 29-year time series North Atlantic groundfish monitored over 5° latitude to west Scotland. These fish show no systematic change species richness through time, but...
It is commonly thought that the biodiversity crisis includes widespread declines in spatial variation of species composition, called biotic homogenization. Using a typology relating homogenization and differentiation to local regional diversity changes, we synthesize patterns across 461 metacommunities surveyed for 10 91 years, 64 checklists (13 500+ years). Across all datasets, found no change was most common outcome, but with many instances differentiation. A weak homogenizing trend 0.3%...
Understanding how disturbance affects biodiversity is important for both fundamental and applied reasons. Here, I investigate disturbances with different ecological effects change metrics. define three main types of effects: D (shifts in mortality rate), B reproductive rates) K carrying capacity). Numerous composite can be defined including any combination these effects. The consequences D, disturbances, as well DBK are examined by comparing metrics before after a disturbance, disturbed...
Global biodiversity assessments have highlighted land-use change as a key driver of change. However, there is little empirical evidence how habitat transformations such forest loss and gain are reshaping over time. We quantified in cover has influenced temporal shifts populations ecological assemblages from 6090 globally distributed time series across six taxonomic groups. found that local-scale increases decreases abundance, species richness, replacement (turnover) were intensified by much...
We present new data and analyses revealing fundamental flaws in a critique of two recent meta-analyses local-scale temporal biodiversity change. First, the conclusion that short-term time series lead to biased estimates long-term change was based on errors simulations used support it. Second, negative relationships between study duration entirely dependent unrealistic model assumptions, use subset data, inclusion one outlier point study. Third, finding decline local biodiversity, after...
Abstract Issue Biodiversity change, that is how the taxonomic identities and abundances of species in ecological systems are changing over time, has two facets: temporal α diversity β diversity. To date, received most attention even though compositional shifts assemblages exceed expectations based on theory. Growing concern about state world’s biodiversity highlights need for better understanding extent, consequences, reorganization systems. Challenges Most methods measuring have been...
Temporal fluctuations in species richness are frequently regulated, exhibiting a tendency to return toward central level.
