Abstract High‐resolution monitoring is fundamental to understand ecosystems dynamics in an era of global change and biodiversity declines. While real‐time automated abiotic components has been possible for some time, biotic components—for example, individual behaviours traits, species abundance distribution—is far more challenging. Recent technological advancements offer potential solutions achieve this through: (i) increasingly affordable high‐throughput recording hardware, which can collect rich multidimensional data, (ii) accessible artificial intelligence approaches, extract ecological knowledge from large datasets. However, automating the facets communities via such technologies primarily achieved at low spatiotemporal resolutions within limited steps workflow. Here, we review existing data processing that enable communities. We then present novel frameworks combine technologies, forming fully pipelines detect, track, classify count multiple species, record behavioural morphological have previously impossible achieve. Based on these rapidly developing illustrate a solution one greatest challenges ecology: ability generate high‐resolution, standardised across complex ecologies.

Conservation scientists have proposed several rankings of the relative importance global threats to biodiversity. Here, we argue that ranking biodiversity depends on local context and metrics used, so has little application for conservation. Several been proposed.

Abstract Biodiversity faces unprecedented threats from rapid global change 1 . Signals of biodiversity come time-series abundance datasets for thousands species over large geographic and temporal scales. Analyses these have pointed to varied trends in abundance, including increases decreases. However, analyses not fully accounted spatial, phylogenetic structures the data. Here, using a new statistical framework, we show across ten high-profile 2–11 that decreases under existing approaches vanish once are for. This is consequence severely underestimating trend uncertainty sometimes misestimating direction.

Abstract The insurance effect of biodiversity—that diversity stabilises aggregate ecosystem properties—is mechanistically underlain by inter‐ and intraspecific trait variation in organismal responses to the environment. This variation, termed response , is therefore a potentially critical determinant ecological stability. However, has yet be widely quantified, possibly due difficulties its measurement. Even when it been measured, approaches have varied. Here, we review methods for measuring from them distil methodological framework quantifying experimental and/or observational data, which can practically applied laboratory field settings across range taxa. Previous empirical studies on most commonly invoke traits as proxies aimed at capturing species' Our approach, based environment‐dependent any biotic or abiotic environmental variable, conceptually simple robust form response, including nonlinear responses. Given derivation data responses, this approach should more directly reflect than trait‐based dominant literature. By even subtle environment dependencies diversity, hope will motivate tests diversity–stability relationship new perspective, provide an mapping, monitoring conserving dimension biodiversity.
