An Examination Of The Correlation Between Shoot Apical Meristem Size And Leaf Heterophylly In Pisum Sativum, Cynthia Mary Halfman
An Examination Of The Correlation Between Shoot Apical Meristem Size And Leaf Heterophylly In Pisum Sativum, Cynthia Mary Halfman
Undergraduate Honors Thesis Collection
This study is a quantitative examination of the ramifications of leaf development as influenced by the size of the shoot apical meristem. I wish not to delve into a genetic examination of the shoot apical meristem but rather into the possible correlation between the apical meristem size and leaf heterophylly. If changes in shoot apical meristem size influence heterophylly in leaves, then as shoot apical meristem changes, leaf characteristics will change. This change may result from two different relationships.

Genetic Change Following Fire In Populations Of A Seed-Banking Perennial Plant, Rebecca W. Dolan, Pedro F. Quintana-Ascencio, Eric S. Menges

Disturbances such as fire have the potential to remove genetic variation, but seed banks may counter this loss by restoring alleles through a reservoir effect. We used allozyme analysis to characterize genetic change in two populations of the perennial Hypericum cumulicola, an endemic of the fire-prone Florida scrub. We assessed genetic variation before and 1, 2, and 3 years after fire that killed nearly all aboveground plants. Populations increased in size following fire, with most seedlings likely recruited from a persistent seed bank. Four of five loci were variable. Most alleles were present in low frequencies, but our large sample …

A New Species Of Streptanthus (Brassicaceae) From Three Peaks In Lake County, California, Rebecca W. Dolan, Richard O'Donnell
Rebecca W. Dolan
Streptanlhus vernalis is a newly described species inhabiting serpentine rock outcrops in the Three Peaks area in Lake County, California. Morphological and allozyme data indicate that this taxon is related to the S. morrisonii complex.

Graminicolous Fungi Of Virginia: Fungi In Collections 2004-2007, Curtis W. Roane
Virginia Journal of Science
Fungus-grass associations recognized in Virginia from 2004 to 2007 are recorded. Many associations are new to the United States (U), eastern United States (EU) and Virginia (V); other associations extend the known distribution of those previously discovered. These reports contribute further to knowledge of the mycoflora of Virginia.
Dispersal And Establishment Both Limit Colonization During Primary Succession On A Glacier Foreland, Chad C. Jones, Roger Del Moral
Dispersal And Establishment Both Limit Colonization During Primary Succession On A Glacier Foreland, Chad C. Jones, Roger Del Moral
Botany Faculty Publications
Plant colonization can be limited by lack of seeds or by factors that reduce establishment. The role of seed limitation in community assembly is being increasingly recognized, but in early primary succession, establishment failure is still considered more important. We studied the factors limiting colonization on the foreland of Coleman Glacier, Washington, USA to determine the importance of seed and establishment limitation during primary succession. We also evaluated the effects of seed predation, drought and existing vegetation on establishment. We planted seeds of seven species into plots of four different ages and found evidence that both seed and establishment limitation …

Life In The Slow Lane: Palmetto Seedlings Exhibit Remarkable Survival But Slow Growth In Florida's Nutrient-Poor Uplands, W. G. Abrahamson, C. R. Abrahamson
Life In The Slow Lane: Palmetto Seedlings Exhibit Remarkable Survival But Slow Growth In Florida's Nutrient-Poor Uplands, W. G. Abrahamson, C. R. Abrahamson
Warren G. Abrahamson, II
The palmettos Serenoa repens and Sabal etonia are crucial foundation species in many peninsular Florida vegetative associations. We monitored the survival and growth of individual palmetto seedlings using two cohorts found in different vegetative associations. Seedling cohorts containing both S. repens and S. etonia were individually tagged in 1989 and have been monitored until 2008, a period of 19 years. One cohort (N = 100 seedlings) occurs in a xeric, “inopina-phase” scrubby flatwoods and a second cohort (N =78 seedlings) lives in a well-drained, “wiregrass-phase” flatwoods. The soils at both sites are very nutrient-poor Entisols that show rapid permeability, low …
