PATTERNS OF SEEDFALL AND SEEDLING ESTABLISHMENT IN AN EAST TEXAS RIVER FLOODPLAIN FOREST: THE CONTRIBUTION OF SEEDLING DYNAMICS TO SPECIES COEXISTENCE (PLANT DEMOGRAPHY, DISPERSAL, TREE REGENERATION, SURVIVORSHIP, MORTALITY)
I investigated spatial and temporal patterns of seed deposition, seedling appearance, survivorship, and growth in an East Texas river floodplain forest from 1980 through 1984, and estimated the importance of several factors including flooding, drought, shading, insect herbivory, and fungal attack …

The demographic impacts of browsing on woody plants in savannas : from individual branches to whole populations
… and models outlining mechanisms of impact on plants and predicting responses are framed in terms of biomass impacts and responses. However, for trees in African savannas, fitness is more closely linked to height than above ground biomass. I evaluate the demographic impacts of browsing, making …

Effects of seed dispersal by gibbons, sambar, and muntjac on Choerospondias axillaris demography, and the disruption of this mutualism by wildlife poaching
… the anthropogenic disruption of this animal-plant mutualism can severely alter the composition of tropical forests. Here I show that illegal poaching has reduced or extirpated several mammal species from national parks in northern Thailand. This, in turn, has negatively affected the …

Demography and leaf physiology of Cornus drummondii in response to disturbance in tallgrass prairie
… disturbance are unknown. Here, I measured ramet demography and leaf physiology of the clonal shrub Cornus drummondii in response to disturbance at the Konza Prairie Biological Station. I quantified the growth rate, reproduction, and ramet demography of C. drummondii in response to fire frequency, …

The Effects of Invasive Plants on Biodiversity Across Spatial Scales
<p>Although introduced plant species are often considered to be one of the most notable anthropogenic threats to biodiversity, their influence on biodiversity remains controversial. Some studies have shown large declines in biodiversity in plant-invaded areas, whereas others have noted that plant …

Trait-based approaches to understanding the response of forest understory herbs to environmental variation
… relationships between abiotic conditions and plant fitness components (i.e., survival, growth, and performance) can provide valuable insights into how populations and communities will respond to future environmental change. Trait-based approaches can thus offer valuable insights into how …
