Temperature and Humidity at Soil Surface on Barro Colorado Island - OPEN 2

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. This data is from a temperature humidity logger placed near the center of the Barro Colorado site macroplots array as part of a macrosystems biodiversity and latitude project supported by the National Science Foundation under Cooperative Agreement DEB#1065836. This data is associated with the project bento bags, but may be used as measures of the soil surface temperature for the dates represented.

生物多样性格局（biodiversity patterns）——包括向热带地区递增的分布规律与生态演替（ecological succession）过程中的单峰曲线特征——是生态学领域的基础性现象。这类格局的成因复杂且相互关联，但温度始终是主导性驱动因子，其影响覆盖从微生物、树木到哺乳动物的各类生物，以及陆地、海洋与淡水所有生境。然而，尽管全球气温持续上升，预测其影响的需求愈发迫切，学界对这些格局背后的核心机制仍未达成广泛共识。本项目旨在构建并检验相关理论，以阐明温度如何通过影响生化过程（biochemical processes）与代谢速率（metabolic rate），进而作用于生物多样性。本研究通过野外标准化调查与野外、实验室受控实验相结合的方式，对沿温度梯度（从寒温带至暖热带）分布的7片森林中的3个类群（taxa）——树木、无脊椎动物（invertebrates）与微生物——的多样性，以及关键的生物地球化学分解过程（biogeochemical processes）进行测定。本数据集源自安装于巴罗科罗拉多岛（Barro Colorado）样地大样方（macroplots）阵列中心附近的温湿度记录仪（temperature humidity logger），该设备是由美国国家科学基金会（National Science Foundation）通过合作协议DEB#1065836资助的大尺度生物多样性与纬度梯度项目的组成部分。本数据集与"bento bags"项目相关联，可作为对应日期内土壤表层温度的测定数据。
