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. Readings of soil temperature and soil moisture were taken with HOBO sensors from November 2011 to November 2012. These sensors were installed at five experimental tree growth plots installed by the Enquist Lab (PI, Brian Enquist) from the University of Arizona as part of a macrosystems biodiversity and latitude project supported by the National Science Foundation under Cooperative Agreement DEB#1065836.

One HOBO Micro Station (Part # H21-002) was installed in each of the five Gentry tree plots at all six experimental sites to monitor continuous variation in soil moisture using Soil Moisture Smart Sensor Part # S-SMB-M005 (http://macroeco.lternet.edu/sites/all/themes/b2_nature/HOBOSoilMoistureSpecifications.pdf) and temperature using 12-Bit Temperature Smart Sensor Part # S-TMB-M002 (http://wpc.306e.edgecastcdn.net/80306E/onsetcomp_com/files/manual_pdfs/7105-I-MAN-S-TMB.pdf). The data logger was secured to a tree. Both sensors were buried 10-15 cm underground by the following method: A hole was dug and the soil probe was inserted with the 2 in side vertical into the wall of the hole until the black part and cord were the only things visible. The temperature probe was placed alongside it and both were buried. The HOBO was set up to record soil moisture and temperature every hour.
