Fernow Experimental Forest site, station Compartment 8, subcompartment A, commerical clearcut treatment in mixed hardwood forest, study of relative frequency of Tilia americana (american basswood) in units of percent on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Fernow Experimental Forest (FER) contains relative frequency of Tilia americana (american basswood) measurements in percent units and were aggregated to a yearly timescale.

Tilia americana leaf senescence phenology:FAB 1 : Forests and Biodiversity Experiment - High density diversity
A forest biodiversity experiment (FAB) focused on trees of our region investigates the consequences of multiple dimensions of tree diversity for soil, food webs, plant communities and ecosystems. FAB is designed to unravel effects of three forms of biological diversity: species richness (SR), functional diversity (FD), and phylogenetic diversity (PD). We define FD as the representation of multiple traits of leaves, roots, seeds, and the whole organism that are correlated with species positions along gradients of resource supply, growth, and decomposition. PD is the representation of evolutionary lineages measured as the genetic distances between species. While PD and FD are often correlated, convergent evolution and adaptive differentiation can decouple them. When functional traits that drive specific ecosystem functions are not phylogenetically conserved, PD and FD may give contrasting predictions. SR, PD, and FD are not independent, and we posit that PD may help explain SR effects, and FD may help explain both PD and SR effects. Thus FAB is designed to examine the separate and combined effects of all three components of diversity for multiple ecosystem functions and to distinguish between ???sampling??? and ???complementarity??? effects of biodiversity. Due to the long lag between planting tree seedlings and determining effects of tree composition and diversity on ecosystem functioning, fewer experiments have been established to elucidate the role of biodiversity in the functioning of forest ecosystems than grassland experiments. FAB will contribute to this gap and is a member of the IDENT and TreeDiv network of forest biodiversity experiments (www.treedivnet.ugent.be). Hypotheses: 1. PD, FD, and SR will all contribute to increased productivity, stability, and diversity of other trophic levels (herbivores, predators, parasitoids, soil microbes, soil flora and fauna) as well as to greater soil C sequestration. 2. Because PD incorporates both the number of species a
Data from: Chloroplast DNA-based phylogeography of Tilia americana (Malvaceae)
A comprehensive picture of how plant species and communities move and evolve over time will require that a variety of species be studied, including plants with different life histories, rarity, and distributions. Relatively few phylogeographic studies have focused on trees. In the present study, the phylogeographic history of Tilia americana, American basswood, was investigated. Samples were collected from throughout the United States and Mexican ranges of basswood, and a phylogenetic analysis was conducted based on sequence data from two non-coding chloroplast DNA regions. The results showed no evidence for the various hypotheses of multiple basswood species within the U. S. A., but there is evidence for a divergence between a Mexican and U. S. A. clade within basswood. Population genetics and spatial statistical analyses were also performed, and supported the conclusion that the only significant geographic barrier within the North American basswoods is found between U. S. A. and Mexico. An attempt was also made to interpret the anomalous geographic distribution of certain chloroplast haplotypes, raising further questions about past migration routes of North American temperate forest trees.
