Meet the Scientist

The Morning Call  online

2014-11-05

Amy Faivre, associate professor and director of the biodiversity and conservation program at Cedar Crest College, will help families examine plants and seeds with powerful microscopes and discuss why some plants have trouble reproducing. The Allentown science center has collaborated with Cedar Crest College and Lehigh University to give families opportunities to meet professional scientists and engineers from the region and take part in hands-on activities related to the work being done every day...

Volunteers plan rescue of Bethlehem's native plant preserve

The Morning Call  online

2012-03-26

Amy Faivre, an associate professor of biological sciences at Cedar Crest College, said coconut mats are a favorite among horticulturists because they hold moisture well and provide enough open space in the fibers for seeds to grow after the invasives are ripped out. The mats also help regulate soil temperature, another important condition in establishing native plants. Without the mats, she said, regular flooding can eventually erode a stream bank, and silt would build up in streams. And silt can be a big problem, she said. "Stream bank erosion is a problem not only for altering the course of the stream and potential increases in flooding, but excessive silt in streams affects macroinvertebrates like dragonfly larvae, mayflies and stoneflies — all important prey for fish," she said. "Coconut fiber mats seem like a good method for assisting native plant species to re-establish along an eroded stream bank."...

Sexual differences in Lobelia spicata populations: floral morphometrics, stigma pollen loads, and pollen tube growth


Plant Species Today

2014-01-01

In many gynodioecious species, gender differences have been documented. Previous studies on populations of Lobelia spicata consistently documented hermaphrodites having larger corollas than females, but inconsistencies as to whether females had higher fruit set or not. In this study we expanded the data set on floral morphology, and to relate morphological differences to potential reproductive output we recorded stigma pollen loads and pollen tube growth to the ovary for both genders from four populations. Also, individuals were bagged to determine if and how much self-pollen deposition occurred on stigmas. Because this species is self-compatible but protandrous, it was thought unlikely to be able to self-fertilize through autogamy...

Multiple causes of seedling rarity in scrub plum, Prunus geniculata (Rosaceae), an endangered shrub of the Florida scrub


American Journal of Botany

2009-01-01

Conservation of an imperiled plant often requires an understanding of its reproductive ecology. Scrub plum (Prunus geniculata) is an endangered Florida shrub endemic to pyrogenic xeric uplands. Although plants are long-lived and may flower profusely, particularly after burning, fruit yield is sparse and seedlings are rare. We investigated potential causes of seedling rarity in scrub plum by studying its floral sex and breeding systems, fruit development, and germination ecology...

Ontogenetic Differences in Heterostylous Plants and Implications for Development from a Herkogamous Ancestor


International Journal of Organic Evolution

2007-01-01

Alternative ontogenetic pathways among heterostylous species of Rubiaceae may reflect differences in their evolutionary histories. In this study, measurements were taken at different developmental stages on a series of long-styled (LS) and short-styled (SS) buds of the heterostylous taxa Psychotria chiapensis, P. poeppigiana, and Bouvardia ternifolia (all Rubiaceae). Results indicated that modifications in growth rates of stamens relative to corollas in all three species led to differences in anther heights between LS and SS flowers...

Variation in Pollen Tube Inhibition Sites Within and Among Three Heterostylous Species of Rubiaceae


International Journal of Plant Sciences

2002-01-01

Pollen tube growth was examined following self, intramorph, and intermorph pollinations in three distylous species of Rubiaceae, the angiosperm family containing the greatest number of distylous taxa. Hand pollinations of Psychotria poeppigiana Muell. Arg., Psychotria chiapensis Standl., and Bouvardia ternifolia (Cav.) Schlecht. were followed by observation of pollen tube growth using fluorescence microscopy. Patterns of pollen tube growth were compared between conspecific floral morphologies, among type of illegitimate pollination, and among taxa...

Population-level variation in the expression of heterostyly in three species of Rubiaceae: does reciprocal placement of anthers and stigmas characterize heterostyly?


American Journal of Botany

2000-01-01

Heterostyly (i.e., reciprocal placement of anthers and stigmas between two or three floral morphs) is hypothesized to enhance outcrossing and reduce selfing. However, few studies have documented reciprocity among individual plants; instead, mean anther and stigma heights for floral morphs are usually reported, masking interindividual variation...
