Florida scrub is a fire-maintained shrub vegetation of well-drained, sandy soils associated with ridge systems that originated as coastal dunes. It is unique to Florida and supports many rare plants and animals. Between 1992 and 2005, we sampled 30 s

Co-occurring species may have differing growth responses to the seasonal timing of climatic events. In this study, we used dendrochronology to examine the importance of seasonal climate on radial stem growth of three co-occurring species in Florida s

We examined annual total digestible nutrient (TDN) production by fruits of eight species ( Quercus chapmanii , Quercus geminata , Quercus inopina , Quercus laevis , Quercus myrtifolia , Carya floridana , Sabal etonia , Serenoa repens ) that account f

Fluctuating asymmetry (FA) represents small, random variation from symmetry, and it has been used as an indicator of plant stress at relatively local scales. In this study, variation in FA was examined at the landscape scale across the whole distribu

The effects of elevated CO 2 on plant growth and insect herbivory have been frequently investigated over the past 20 years. Most studies have shown an increase in plant growth, a decrease in plant nitrogen concentration, an increase in plant secondar

Patterns in soil moisture availability affect plant survival, growth and fecundity. Here we link patterns in soil moisture to physiological and demographic consequences in Florida scrub plants. We use data on different temporal scales to (1) determin

Atmospheric CO2 concentrations have increased exponentially over the last century and continuing increases are expected to have significant effects on ecosystems. We investigated the interactions among atmospheric CO2, foliar quality, and herbivory w

Much research on the effects of elevated CO2 on forest trees has focused on quantitative changes in photosynthesis, secondary chemistry, and plant biomass. However, plant fitness responses to rising CO2 should also include quantitative measures of re

The number of seeds produced by a population of woody plants can vary markedly from year to year. Unfortunately, knowledge of the patterns and causes of crop-size variation is limited, and most studies have examined only single species in a single me

The unabated increase in global atmospheric CO(2) is expected to induce physiological changes in plants, including reduced foliar nitrogen, which are likely to affect herbivore densities. This study employs a field-based CO(2 )enrichment experiment a
