Abstract

Why aggressive traits evolve in some species but not in others is poorly understood. We modeled the population dynamics of the extinct Mauritius dodo and Rodrigues solitaire to examine divergent pathways in the evolution of aggression. Whereas the dodo conformed to island syndrome predictions of tameness, its sister-taxon the solitaire evolved strong sexual dimorphism and aggressive traits. We computed rates of change in island size from sea level modeling and connected island size change to population dynamics by integrating a Hawk-Dove game theory model for territory competition with a population model. We find that the rapid rate of decrease in island size likely was an important trigger for the onset of aggressive behavior and that aggressive behavior becomes fixed if a tipping point is reached where island size falls below a critical threshold.

海平面上升与岛屿侵略的演变。

为什么一些物种会进化出攻击性特征，而另一些物种却不会，人们对此知之甚少。我们模拟了已灭绝的毛里求斯渡渡鸟和罗德里格斯鸻的种群动态，以研究攻击性进化的不同途径。渡渡鸟符合岛屿综合征关于驯化的预测，而其姊妹类群单舌鸟则进化出了强烈的性二型和攻击性特征。我们通过海平面建模计算了岛屿面积的变化率，并通过将领土竞争的鹰鸽博弈论模型与种群模型相结合，将岛屿面积变化与种群动态联系起来。我们发现，岛屿面积的快速减小可能是引发攻击行为的一个重要诱因，如果达到一个临界点，岛屿面积减小到临界阈值以下，攻击行为就会固定下来。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
