How humans have shaped tropical forest composition and structure, and how biodiversity recovers followinghuman disturbance lacks long-term observations. BLADEN will address this critical knowledge gap bydetermining anthropogenic impacts on biodiversity in a Mesoamerican tropical forest over 13,000 years. Thedestruction of tropical forests and loss of biodiversity is one of the greatest challenges humanity faces,threatening essential ecosystem services, including food security, the provisioning of medicines and theregulation of Earth's climate. Developing datasets to understand how humans shaped ecosystems and howbiodiversity recovers following disturbance is critical for informed conservation strategies and securingglobal futures. Despite extensive evidence of past landscape impacts, processes of natural regeneration inresponse to the type, intensity, and duration of disturbance lack data. BLADEN will fill this knowledge gap.The multidisciplinary 5-year project couples past and modern biodiversity indicators at high spatial andchronological resolution in the Bladen Nature Reserve, southern Belize. The study will assess the influenceof the range of past disturbances associated with the ancient Maya and their forebears to determinecorrelations of past vegetation management with modern forest composition and genomic variation in keytree species. My broad experience and successes leveraging novel proxies of human disturbance in theNeotropics place me in a privileged position to lead this interdisciplinary study. The results of the projectwill reveal insight into how humans have shaped tropical forests and provide critical baseline data on theeffectiveness of natural regeneration to restore biodiversity in response to the range of human disturbances.

人类如何塑造热带森林的组成和结构，以及生物多样性如何在人类干扰后恢复，缺乏长期观察。BLADEN将通过确定13,000年来人类活动对中美洲热带森林生物多样性的影响来解决这一关键的知识缺口。热带森林的破坏和生物多样性的丧失是人类面临的最大挑战之一，威胁着基本的生态系统服务，包括粮食安全、药品供应和地球气候的调节。开发数据集以了解人类如何塑造生态系统以及生物多样性如何在干扰后恢复对于明智的保护战略和保障全球未来至关重要。尽管有大量的证据表明过去的景观影响，自然再生的过程inresponse的类型，强度和持续时间的干扰缺乏数据。BLADEN将填补这一知识空白。多学科的5年项目在伯利兹南部的布莱登自然保护区以高空间和时间分辨率将过去和现代生物多样性指标结合起来。该研究将评估与古玛雅及其祖先有关的过去干扰范围的影响，以确定过去植被管理与现代森林组成和关键树种基因组变异的相关性。我在新热带地区利用人类干扰的新代理的广泛经验和成功使我处于领导这项跨学科研究的特权地位。该项目的结果将揭示人类如何塑造热带森林，并提供有关自然再生在应对一系列人类干扰时恢复生物多样性的有效性的关键基线数据。
