Patterns and drivers of temporal variability for native and invasive Okinawa ant communities

我完成了对冲绳蚂蚁群落活动的时间变异性的分析，这有助于提供越来越多的证据，表明人类发展可能是导致昆虫自然季节模式丧失的原因。重要的是，这是在亚洲亚热带地区进行的第一项研究，也是日本仅有的一项研究。人类发展程度较高的地点与森林覆盖率较高的地点相比，群落季节性减弱，同步性降低(所有物种具有相似的活动模式)，随机性更高。有趣的是，我们发现相同的物种(甚至大多数外来物种)在森林中的季节性比发达地区更高，这抵消了整个岛屿群落组成差异的潜在影响。我们还发现，与外来物种相比，我们在森林中观察到的强烈季节性模式更具同步性。我与同事在BioRxiv(https://doi.org/10.1101/2023.01.17.523860)，)上发表了我们的论文，我们正在努力将其发表在一本顶级生态学杂志上。我在日本举行的全国会议(2022年日本生态学会)和学术会议研讨会(东北大学-OIST第三次生物多样性联合研讨会：从基因和物种到生态系统服务和复原力，2022年)上介绍了这项工作。

I completed my analysis of temporal variability of the activity of Okinawan ant communities, which contributed to the growing evidence that human development may be responsible for loss of natural seasonal patterns in insects. Importantly, this is the first study to do so in the Asian subtropics, and one of the only for Japan. Sites with higher human development had diminished community seasonality, reduced synchrony (all species having similar activity patterns), and higher randomness compared to sites with greater forest cover. Interestingly, we found that the same species (even most alien species) have higher seasonality in the forest than in developed areas, negating potential effects of community composition differences across the island. We also found that the strong seasonal patterns we observed in the forest were more synchronous for native than alien species.I published our paper with colleagues on BioRxiv (https://doi.org/10.1101/2023.01.17.523860), and we are working on getting it published in a top ecology journal. I presented on this work at a national conference in Japanese (Ecological Society of Japan 2022), and at an academic meeting seminars (Tohoku University - OIST 3rd Joint Workshop on Biodiversity: From Genes and Species to Ecosystem Services and Resilience, 2022).
