Land-use change and forest biodiversity Land-use change by humans, particularly forest loss, is influencing Earth's biodiversity through time. To assess the influence of forest loss on population and biodiversity change, Daskalova et al. integrated data from more than 6000 time series of species' abundance, richness, and composition in ecological assemblages around the world. Forest loss leads to both positive and negative responses of populations and biodiversity, and the temporal lags in population and biodiversity change after forest loss can extend up to half a century. Land-use change precipitates divergent population and biodiversity change. This analysis has consequences for projections of human impact, ongoing conservation, and assessments of biodiversity change. Science, this issue p. 1341 Declines in forest cover amplify both gains and losses in plant and animal population abundance and diversity over time. Global biodiversity assessments have highlighted land-use change as a key driver of biodiversity change. However, there is little empirical evidence of how habitat transformations such as forest loss and gain are reshaping biodiversity over time. We quantified how change in forest cover has influenced temporal shifts in populations and ecological assemblages from 6090 globally distributed time series across six taxonomic groups. We found that local-scale increases and decreases in abundance, species richness, and temporal species replacement (turnover) were intensified by as much as 48% after forest loss. Temporal lags in population- and assemblage-level shifts after forest loss extended up to 50 years and increased with species’ generation time. Our findings that forest loss catalyzes population and biodiversity change emphasize the complex biotic consequences of land-use change.

景观规模的森林丧失是人口和生物多样性变化的催化剂

土地利用变化和森林生物多样性 人类对土地利用的改变，特别是森林的丧失，正随着时间的推移影响着地球的生物多样性。为了评估森林丧失对人口和生物多样性变化的影响，Daskalova 等人。来自世界各地生态组合中物种丰度、丰富度和组成的 6000 多个时间序列的综合数据。森林丧失导致人口和生物多样性的积极和消极反应，森林丧失后人口和生物多样性变化的时间滞后可长达半个世纪。土地利用的变化促成了人口和生物多样性的变化。这种分析对人类影响的预测、持续的保护和生物多样性变化的评估都有影响。科学，这个问题 p。1341 随着时间的推移，森林覆盖率的下降会放大动植物种群数量和多样性的收益和损失。全球生物多样性评估强调土地利用变化是生物多样性变化的关键驱动因素。然而，几乎没有经验证据表明，随着时间的推移，栖息地的变化（例如森林的丧失和增加）如何重塑生物多样性。我们从 6090 个全球分布的六个分类群的时间序列中量化了森林覆盖的变化如何影响种群和生态组合的时间变化。我们发现，在森林消失后，局部尺度的丰度、物种丰富度和时间物种更替（周转）的增加和减少加剧了 48%。森林丧失后种群和组合水平变化的时间滞后延长至 50 年，并随着物种的世代时间而增加。我们的研究结果表明，森林丧失会催化人口和生物多样性变化，这强调了土地利用变化的复杂生物后果。
