**Coursera课程总结：生物物理场方法** 本课程“生物物理场方法”提供了一种实用的生物物理生态学方法，该方法运用物理概念、原理和技术来解读动物与环境的相互作用。课程将探讨物理定律（如热力学定律）如何影响动植物的丰度和分布，微气候的本质，生态位，以及生理学与进化生态学的整合。 课程旨在通过具体的生态学问题，教授在野外可靠测量温度和湿度的实用方法及其物理驱动因素。课程强调，在野外研究中，温度和湿度的测量往往缺乏对其物理原理的关注，这可能导致测量结果不仅无意义，甚至具有误导性。 课程共分为九个单元，每个单元包含多个部分。 * **第一部分** 重点讲解热的物理学，包括能量、温度、它们之间的区别，以及生物系统如何受热力学定律的制约。 * **第二部分** 深入探讨水的物理学，包括其依数性（colligative properties）以及从冰到水、从水到水蒸气的相变过程的能量学。 * **第三部分** 专注于水的势能（water potential）的物理学。 所有这些概念都通过共同的“货币”——能量——联系起来，并通过多个实例展示，说明恰当应用这些概念如何能更深入地理解生物体及其环境。 本课程全部在纳米比亚实地拍摄。此外，它还有一个配套的野外课程，来自美国、以色列和纳米比亚的学生将在纳米布沙漠的Gobabeb纳米布研究中心汇合，将生物物理生态学的原理应用于适应性和生物物理生态学的现实问题。 **授课教授：** Scott Turner（生物学荣誉教授）
Biophysical field methods online offers a practical approach to biophysical ecology, which applies physical concepts, principles and techniques to the interpretation of animal-environment interactions. These include: how physical laws, such as the laws of thermodynamics, affect the abundance and distribution of animals and plants; the nature of microclimate, the ecological niche; and the integration of physiology and evolutionary ecology.With specific ecological questions in mind, we aim to teach practical methods for reliably measuring temperature and humidity and their physical drivers in the field. Temperature and humidity are commonly reported in field studies, but they are usually measured with little attention to the physical principles that make those measurements meaningful and reliable. Without such attention, the results can be worse than meaningless: they can be misleading. The course is composed of nine lessons, each subdivided into several sections. The first third of the course deals with the physics of heat: energy, temperature, the differences between them and how biological systems are constrained by the laws of thermodynamics. Next the course delves into the physics of water, its colligative properties, and the energetics of phase changes from ice to liquid water and liquid water to water vapor. Then, the course focuses on the physics of water potential. All these concepts are tied together through their common currency-energy-and are demonstrated with several examples of how these concepts properly applied can lead to a deeper understanding of the organism and its environment.This entire course is filmed on location in Namibia. BPFM is complemented by a field course, where students from the USA, Israel and Namibia rendezvous in the Namib desert, at Gobabeb, Namib Research Institute, to apply the principles of biophysical ecology to real-world problems of adaptation and biophysical ecology.
