Host plant choice by marine herbivores: ecological, genetic and historical constraints

海洋食草动物对寄主植物的选择：生态、遗传和历史限制。了解决定食草动物选择植物的因素对于预测食草动物对植物的生态影响和食草动物对植物的适应至关重要。这项建议旨在确定海洋草食动物的寄主选择的进化如何受到生态、遗传和历史因素的限制。它将决定植物的空间排列如何改变宿主的使用，以及食草动物的进化变化是否受到食草动物特征之间的遗传关系的限制。预测食草动物植物选择的重要进化假说的普遍性将通过将这种理论扩展到新的有机体和环境来检验。

Host plant choice by marine herbivores: ecological, genetic and historical constraints. Understanding the factors that determine plant choice by herbivores is crucial to predicting the ecological effects of herbivores on plants and herbivore adaptation to plants. This proposal aims to establish how evolution of host choice by a marine herbivore is constrained by ecological, genetic and historical factors. It will determine how the spatial arrangement of plants modifies host use, and whether evolutionary change by herbivores is constrained by genetic relationships among herbivore traits. The generality of important evolutionary hypotheses that predict plant choice by herbivores will be tested by extending such theory to new organisms and environments.
