This dataset, collected from Duke Forest Free Air CO2 Enrichment (FACE) – Forest-Atmosphere Carbon Transfer and Storage (FACTS-I) experiment, includes variables describing the meteorological conditions above canopy, within canopy, and soil depending on the variable. The Duke FACE experiment was located in a loblolly pine (Pinus taeda L.) plantation established in 1983. Naturally regenerated broadleaved species including sweetgum (Liquidambar styraciflua L.) and tulip poplar (Liriodendron tulipifera L.), mostly in the overstory, and winged elm (Ulmus alata Michx.) and red maple (Acer rubrum L.) were common in the understory. The FACE experiment commenced with two plots (plots 7-8) in 1994 (Oren et al. 2001), with six additional plots (plots 1-6) coming online on 27 August 1996. The CO2 enrichment was terminated on 31 October 2010 and post-enrichment data collection continued through 2012. Complete fertilization was applied annually to half of plots 7-8 from 1998 to 2004. The nutrient addition experiment expanded to half of plot 1-6 with a common protocol of N-fertilization in 2005. N-fertilization continued until 2012. The data range varied by sensor availability. A summary of information about variable name and data range can be found in the ‘FileDescription_[variable_name].txt’ files.

This dataset describing the responses of plant and soil pools and fluxes to elevated atmospheric CO2 concentration and increased nitrogen supply was collected from Duke Forest Free Air CO2 Enrichment (FACE) – Forest-Atmosphere Carbon Transfer and Storage (FACTS-I) experiment from 1996 to 2012. The dataset includes data files for allometry (diameter at breast height, tree height, and height to live crown base), leaf area index, biomass (stem, branch, foliage, and root biomass, tree density, and basal area), net primary productivity (stem, branch, foliage, reproductive, and coarse root NPP), sap flux density, soil CO2 efflux, and stem temperature. Data files were formatted as .csv (Microsoft Excel or other spreadsheet programs can be used to read the format) and file descriptions, including variable name, unit, and data range, can be found in ‘FileDescription_[data_name].txt’ files. The Duke FACE experiment was in a loblolly pine (Pinus taeda L.) plantation established in 1983. Naturally regenerated broadleaved species including sweetgum (Liquidambar styraciflua L.) and tulip poplar (Liriodendron tulipifera L.), mostly in the overstory, and winged elm (Ulmus alata Michx.) and red maple (Acer rubrum L.) were common in the understory.

Presentation for the 2016 VIVO conference

Climate change is restructuring forests of the United States, although the details of this restructuring are currently uncertain. Rising temperatures of 2 to 8 deg C and associated changes in soil moisture will shift the competitive balance between species that compete for light and water, changing their abilities to produce seed, germinate, grow, and survive. We are using large scale experiments to determine the effects of warming on the most sensitive stage of species distributions, i.e., recruitment, in mixed deciduous forests in southern New England and in the Piedmont region of North Carolina. Two questions organize our proposed research: (1) Might temperate tree species near the "warm" end of their range in the eastern United States decline in abundance during the coming century due to projected warming? and (2) Might trees near the "cool" end of their range in the eastern United States increase in abundance, or extend their range, during the coming 100 years because of projected warming? To explore these questions, we are exposing seedlings to air and soil warming experiments in two eastern deciduous forest sites; one at the Harvard Forest (HF) in central Massachusetts, and the other at the Duke Forest (DF) in the Piedmont region of North Carolina. We focus on tree species common to both Harvard and Duke Forests (such as red, black, and white oaks), those near northern range limits (black oak, tulip poplar), and those near southern range limits (yellow birch, sugar maple). At each site, we plant seeds in common gardens established in temperature-controlled, open-top chambers. The experimental design is replicated and fully factorial and involves three temperature regimes (ambient, +3 deg C and +5 deg C) and two light regimes (closed forest canopy (low light) and gap conditions (high light)). Measured variables include Fall/Spring responses to temperature and mid-Summer responses to low soil moisture. This research will advance our understanding of how the abundances and geographic distributions of several important eastern tree species near the cool and warm ends of their ranges will change during the century because of projected warming. Warming-induced changes in eastern tree abundances and distributions have the potential to affect both the quality and quantity of goods and services provided by eastern forests, and will therefore be of importance to society.

These data were obtained from harbour porpoises (Phocoena phocoena) equipped with satellite-linked transmitters in the Gulf of Maine. All porpoises were obtained from herring weirs on the island of Grand Manan, New Brunswick Canada (44°45 N 67°45 W) during the summer months (July to September). Details on each porpoise are given in the summary table. Positional data are obtained via Service ARGOS (http://www.argosinc.com/). See Read and Westgate (1997) for complete details of tagging methods.

Open textbooks, which provide students with electronic access to texts without fees, have been developed as alternatives to commercial textbooks. Building on prior quasi-experiments, the purpose of this study is to experimentally compare an open and commercial textbook. College students (N = 144) were randomly assigned to read an excerpt from an open or commercial textbook, answer questions about content, and indicate their perceptions of textbook quality. Learning was similar between textbook types. Perceptions differed in that the discussion of research findings was reported as higher quality in the open textbook while the visuals and writing were reported as higher quality in the commercial textbook. Neither perceptions of research findings nor visuals correlated with learning performance. However, perceptions of writing quality and everyday examples were correlated with learning performance. Findings may inform initiatives for open textbook adoption as well as textbook development, but are limited due to the use of an excerpt. Reading to learn is a fundamental activity for knowledge construction (Duke et al., 2003; Alfassi, 2004; Maggioni et al., 2015). Textbooks are common educational tools for reading to learn, even in the digital age (Fletcher et al., 2012; Knight, 2015; Illowsky et al., 2016). The rising cost of commercial textbooks, along with the affordances of the internet and growing interest in expanding access to knowledge, has brought about the development of open textbooks, which students can access electronically without cost (Smith, 2009). There have been multiple studies indicating that students' learning from and opinions of open textbooks are similar to or better than those of commercial textbooks (e.g., Clinton, 2018; Lawrence and Lester, 2018; Medley-Rath, 2018; Cuttler, 2019; Grissett and Huffman, 2019). However, these studies have all been quasi-experimental or correlational; therefore, causal claims were not possible. Moreover, students in these studies were aware that the open textbooks were free whereas the commercial textbooks were not, which could bias their attitudes (Clinton, 2019). An experimental examination with participants who are naive to the cost of the textbook would address the confounds related to student awareness of cost. The purpose of this experiment is to examine students' learning from and perceptions of an open textbook compared to a commercial textbook.
