Spring 2007 warmth and frost: phenology, damage and refoliation in a temperate deciduous forest by Augspurger, Carol K.

“…1. Climate change is predicted to bring earlier bud break and perhaps a greater risk of frost damage to developing leaves and flowers. Given the rarity and…”

Understory plants evade shading in a temperate deciduous forest amid climate variability by shifting phenology in synchrony with canopy trees by Augspurger, Carol K, Salk, Carl F

“…Global warming is leading understory and canopy plant communities of temperate deciduous forests to grow leaves earlier in spring and drop them later in…”

Early spring leaf out enhances growth and survival of saplings in a temperate deciduous forest by Augspurger, Carol K

“…Saplings of many canopy tree species in winter deciduous forests receive the major portion of their light budget for their growing season prior to canopy…”

Frost damage and its cascading negative effects on Aesculus glabra by Augspurger, Carol K.

“…Frost damage and re-foliation are seldom quantified for forest species, but are of ecological and evolutionary importance. This study of Aesculus glabra (Ohio…”

Host Specificity of Pathogenic Pythium Species: Implications for Tree Species Diversity by Augspurger, Carol K., Wilkinson, Henry T.

“…In the Janzen-Connell hypothesis, host-specific natural enemies enhance species diversity and influence the structure of plant communities. This study tests…”

Intraspecific variation in seed dispersal of a Neotropical tree and its relationship to fruit and tree traits by Augspurger, Carol K., Franson, Susan E., Cushman, Katherine C., Muller‐Landau, Helene C.

“…The distribution of wind‐dispersed seeds around a parent tree depends on diaspore and tree traits, as well as wind conditions and surrounding vegetation. This…”

Concordance of long-term shifts with climate warming varies among phenological events and herbaceous species by Augspurger, Carol K., Zaya, David N.

“…Many temperate herbs now flower earlier than a few decades ago. Little is known about other phenological events, despite the importance of life history…”

Constraints of cold and shade on the phenology of spring ephemeral herb species by Augspurger, Carol K., Salk, Carl F.

“…1. Spring ephemeral herb species in temperate deciduous forests are active above-ground only briefly each year. This study tested experimentally how two…”

Incorporating animal behavior into seed dispersal models: implications for seed shadows by Russo, Sabrina E., Portnoy, Stephen, Augspurger, Carol K.

“…Seed dispersal fundamentally influences plant population and community dynamics but is difficult to quantify directly. Consequently, models are frequently used…”

Wind dispersal is predicted by tree, not diaspore, traits in comparisons of Neotropical species by Augspurger, Carol K., Franson, Susan E., Cushman, Katherine C.

“…Summary The seed shadow created by wind dispersal around parent trees may be affected by functional traits, as well as wind conditions and surrounding…”

The effect of leaf litter on early seedling establishment in a tropical forest by Molofsky, Jane, Augspurger, Carol K.

“…The presence of leaf litter of different depths within a tropical forest creates many different microsites for plant establishment. The amount and distribution…”

Causes of Spatial Patterns of Dead Trees in Forest Fragments in Illinois by Lin, Y., Hulting, Melissa L., Augspurger, Carol K.

“…Natural disturbances introduce spatial heterogeneity into forests by causing non-random mortality of trees. We examined whether wind was the primary cause of…”

Seedling Survival of Tropical Tree Species: Interactions of Dispersal Distance, Light‐Gaps, and Pathogens by Augspurger, Carol K.

“…This study tested the hypotheses that seed dispersal enhances seedling survival by (1) escape of distance—dependent or density—dependent mortality or both, and…”
