Overcoming challenges in the monitoring and modelling of ecological data at scale
报告摘要
This research explores the complexities of monitoring and modelling ecological data at scale, with a primary focus on the transferability of models across diverse temporal and spatial contexts. First, I will outline a case study on the management of herbicide-resistant weeds. The work addresses how to apply models at regional and national scales While traditional demographic models can experience numerical instability I show how alternative model structures are more robust and at the same time permit data collection at scale. By integrating hierarchical surveys across hundreds of fields with advanced automated monitoring via Unmanned Aerial Vehicles (UAVs), our research develops bespoke models capable of simulating novel management combinations at the field and farm scale. Moving to larger temporal and spatial scales, in the second part of my talk I will examine how accounting for spatial and phylogenetic structures in large-scale datasets can reveal significant uncertainties in the status of global biodiversity change. These methodologies aim to provide more reliable, predictive tools for both policy makers and land managers.

气候变化下植物有性繁殖性状的响应与多尺度生态效应
报告摘要
植物繁殖性状与生长性状共同构成了植物功能性状的核心维度，对于理解植物适应策略、生态系统功能及生物多样性维持具有重要的生态学意义。当前，气候变化正导致植物与传粉者关键性状之间发生错配，引发生殖互作网络衰退与生物多样性丧失。然而，已有研究多关注营养性状，开花植物有性繁殖性状在气候变化下的响应及其多尺度生态效应仍未得到足够重视，这限制了我们准确预测未来生物多样性变化的能力。本报告基于跨群落及宏观时空尺度构建的开花植物有性繁殖性状数据集，系统解析了这些性状在群落构建中的关键作用、地理分布格局、演化趋势及其对气候变化的响应。本研究将功能性状的研究框架从营养性状拓展至繁殖性状，揭示了有性繁殖性状响应气候变化的时空动态及其对植物多样性格局的关键影响，深化了对全球变化下植物-传粉者互作关系演变的理解。相关结果挑战了关于特定繁殖策略促进多样性的传统认知，为未来生物多样性保护与生态系统管理提供了新的理论视角与预测依据。
