Regeneration Dynamics in Old -Growth and Second-Growth Southern Appalachian Cove Forests
Regeneration dynamics in an old-growth and a second-growth cove forest in the Great Smoky Mountains of eastern Tennessee were studied over the course of four contiguous growing seasons. Woody shrub and herbaceous species in the regeneration layer were also investigated. The effects of disturbance …

NATURAL REGENERATION DYNAMICS AND SURVIVAL INFLUENCED BY ABIOTIC AND BIOTIC FACTORS IN A BOTTOMLAND HARDWOOD FOREST
… desired, native species. This research assessed regeneration dynamics and one-year survival in a seasonally-flooded bottomland hardwood forest at Boggy Slough Conservation Area in East Texas to identify abiotic and biotic factors important for successful establishment of native regeneration. …

Forest and woodland regeneration dynamics and persistence in the human- modified landscape of Greater Gombe Ecosystem, Tanzania
… be an effective strategy for promoting forest regeneration, persistence of mature forest patches, and conservation in human-modified landscapes. However, few studies have systematically evaluated its effectiveness. In particular, limited empirical evidence exists on the influence of these …

When do propagules matter? The role of ecological filters and regeneration dynamics during community assembly in tallgrass prairie restorations
… and contribution of propagules for community regeneration in degraded environments. Three studies were conducted to elucidate the role of regeneration dynamics and dominant species on community assembly during tallgrass prairie restoration. In the first study, patterns in the abundance, …

Compounding Fire Disturbance History Encourages Coast Redwood (Sequoia sempervirens) Regeneration and Community Dominance
… coast redwood forest structure, composition, and regeneration dynamics and to evaluate the effects of abiotic soil qualities on post-fire regeneration. I mapped and sampled coast redwood forests burned in 1985, both 1985 and 1999, 2008, and 2013; modeled regeneration as a function of burn history, …

Forest Densification Over 85 Years in a Sierra Nevada Mixed-Conifer Forest Decreases Conifer Regeneration and Limits Survival
… mixed conifer forests has decreased conifer regeneration and survival. Increases in overstory biomass and decreases in canopy heterogeneity, along with decreases in shrub cover in the understory, has created unfavorable establishment site conditions for conifer species. Establishment site …

Regeneration of fire-adapted species in the Sierra Nevada contingent upon repeated fuel treatments and available soil moisture
… prescriptions often do not explicitly consider regeneration dynamics. The increasing ubiquity of fuel treatments, and the necessity to implement them repeatedly, calls for a better understanding of how treatments may influence tree seedling communities and shape stand trajectories over time, yet …

Methods and technologies for high-throughput and high-content small animal screening
… library for factors affecting neural regeneration following femtosecond laser microsurgery of C. elegans using these technologies. This screen identifies the kinase inhibitor staurosporine as a strong inhibitor of neural regeneration, and does so in a concentration and neuronal cell …

Thresholds for sustainable regeneration in urban restoration plantings in Hamilton City, New Zealand
… and understorey indicating some limitation for regeneration or colonisation in young urban forests. The richness of bird-dispersed native species in urban forest patches increased with proximity and size of good quality native vegetation but no other effects of dispersal mode on urban native …

Remote Sensing Characterization of Ecosystem Structure and Functional Types to Inform on Biodiversity Conservation in the Lowland Chocó Rainforest
… of forest degradation and study of natural regeneration dynamics of managed conservation sites in Canandé region of the lowland Chocó. The thematic feature of this chapter focuses on evaluating the status of forest regeneration at the landscape scale by utilizing measures of texture derived …
