Why are particular species present in some locations, but not others? This is a simple, fundamental ecological question, yet surprisingly, our answers on this point remain far from complete. Using an integrated, systems-based approach, we will determine the interplay between: (i) birth, death and movement rates, (ii) species interactions, and (iii) the constraints of the physical environment (temperature, rainfall, soil type), which determine the limits of species' ranges. Our models will provide Australian conservation managers with a novel, validated toolbox to explore the trade-offs, and synergies, inherent in trying to adapt to climate change and other stressors on biodiversity.

为什么某些地方存在特定的物种，而不是其他地方？这是一个简单的基本生态问题，但令人惊讶的是，我们在这一点上的答案远非完整。使用基于系统的集成方法，我们将确定：（i）出生，死亡和运动率，（ii）物种相互作用，以及（iii）物理环境的约束（温度，降雨，土壤类型），这些限制确定了物种范围的限制。我们的模型将为澳大利亚的保护经理提供一个新颖的，经过验证的工具箱，以探索权衡取舍和协同作用，这些工​​具箱固有，试图适应气候变化和其他对生物多样性的压力。
