Bird Species Commonly Present at Harvard Forest LTER

Patterns of biodiversity, such as the increase toward the tropics and the peaked curve during ecological succession, are fundamental phenomena for ecology. Such patterns have multiple, interacting causes, but temperature emerges as a dominant factor across organisms from microbes to trees and mammals, and across terrestrial, marine, and freshwater environments. However, there is little consensus on the underlying mechanisms, even as global temperatures increase and the need to predict their effects becomes more pressing. The purpose of this project is to generate and test theory for how temperature impacts biodiversity through its effect on biochemical processes and metabolic rate. A combination of standardized surveys in the field and controlled experiments in the field and laboratory measure diversity of three taxa -- trees, invertebrates, and microbes -- and key biogeochemical processes of decomposition in seven forests distributed along a geographic gradient of increasing temperature from cold temperate to warm tropical.

生物多样性格局（如向热带地区递增的格局以及生态演替过程中的单峰曲线格局）是生态学的核心基础现象。此类格局的成因多元且相互交织，但温度已成为覆盖从微生物、树木到哺乳动物的各类生物，以及陆地、海洋与淡水生境的主导驱动因子。尽管当前全球气温持续升高，预测其影响的现实需求也愈发紧迫，但学界对其背后的内在机制尚未形成广泛共识。本项目旨在构建并验证相关理论，以阐明温度如何通过影响生化过程与代谢速率，进而作用于生物多样性。本项目结合野外标准化调查与野外、室内控制实验，对沿温度递增地理梯度分布的7片森林中的3个类群（树木、无脊椎动物与微生物）的多样性，以及关键的分解生物地球化学过程开展测定。本数据集所附的马萨诸塞州哈佛大学森林长期生态研究站（LTER）鸟类物种名录，于2013年10月17日从http://harvardforest.fas.harvard.edu:8080/exist/xquery/data.xq?id=hf058 检索获取，该名录隶属于由美国国家科学基金会合作协议DEB#1065836资助的大系统生物多样性与纬度梯度项目。
