Summer To Autumn Population Of Wild Eumaeus Atala On The Ft. Lauderdale Campus Of Nova Southeastern University, Alexandra M. Lens Aug 2021

Summer To Autumn Population Of Wild Eumaeus Atala On The Ft. Lauderdale Campus Of Nova Southeastern University, Alexandra M. Lens

Mako: NSU Undergraduate Student Journal

Eumaeus atala is an endangered tropical butterfly native to the Caribbean and some parts of Florida, USA. Following population reductions primarily due to habitat loss, E. atala populations are now increasing due to conservation efforts of its cycad host plants, especially Zamia integrifolia (coontie). The purpose of this study was to observe, document, and measure the population of wild E. atala on the Ft. Lauderdale, Florida campus of Nova Southeastern University where landscaping use of host plants supports a natural population of E. atala. Forty-four host plants located in two different sites were observed for 14 weeks. One site …


Partnering With Archivists To Process The Manuscript Collection Present At The Marshall University Herbarium, Pamela Puppo, Lori Thompson Aug 2021

Partnering With Archivists To Process The Manuscript Collection Present At The Marshall University Herbarium, Pamela Puppo, Lori Thompson

Biological Sciences Faculty Research

The Marshall University Herbarium (MUHW) is located on the third floor of the Science Building at Marshall University in Huntington, West Virginia, United States. It was founded in the 1930's by Dr. Frank A. Gilbert when Marshall was still Marshall College. Today, MUHW is the second largest herbarium in West Virginia with about 50,000 specimens, including 20 types. Mostly composed of vascular plants, the herbarium also contains small collections of non-vascular plants, fungi, algae, fossils, and some ethnobotanical material, mainly brought from Ecuador by one of the former curators, Dr. Dan Evans between the 1980's and 2000's. Apart from these …


Sciadopitys Verticillata (Japanese Umbrella Pine), #1065-1067, Grace C. Kubat Apr 2021

Sciadopitys Verticillata (Japanese Umbrella Pine), #1065-1067, Grace C. Kubat

BIO 140 Arboretum Project

Over the course of the 2021 spring semester, I observed a grove of Japanese Umbrella Pines. These trees are a part of the University's arboretum. In addition to making weekly observations, I researched the cultural significance of the Umbrella Pines. My research will hopefully contribute to future projects regarding the trees and help to enrich the University's arboretum project.

Tilia Cordata (Littleleaf Linden) #1059, Heather Noel Mckee Apr 2021

Tilia Cordata (Littleleaf Linden) #1059, Heather Noel Mckee

BIO 140 Arboretum Project

In this paper I studied the Tilia cordata, more commonly known as the Littleleaf Linden, over the course of three months. I included the history and uses of the Linden tree along with its symbolic value in European culture. This tree symbolizes friendship and peace which coincides with the critical concerns of the Sisters of Mercy.


Evolution And Development Of Staminodes In Paronychia (Caryophyllaceae), Andrea D. Appleton Mar 2021

Evolution And Development Of Staminodes In Paronychia (Caryophyllaceae), Andrea D. Appleton

Honors College Theses

Staminodes are infertile stamens that have evolved numerous times in flowering plants and exhibit a vast array of forms and functions. Variation in staminodes suggests that numerous evolutionary processes underlie their origins, but to understand their how and why they evolved, comparative studies are needed in groups of closely related species. Identifying structures as staminodes is not always straightforward and sometimes requires corroborating phylogenetic and developmental evidence. Staminodial structures in Paronychia (Caryophyllaceae), for example, vary in shape and size and have been referred to as both petals and staminodes, rendering their homology uncertain. The development of staminodes was compared across …


Patterns Of Genetic Divergence Across Geographically Variable Populations Of Xanthisma Gracile (Asteraceae), Lavanya Challagundla, Lisa E. Wallace Jan 2021

Patterns Of Genetic Divergence Across Geographically Variable Populations Of Xanthisma Gracile (Asteraceae), Lavanya Challagundla, Lisa E. Wallace

Biological Sciences Faculty Publications

Premise of research. Numerous biotic and abiotic factors can contribute to local selection and lead to geographic structure and genetic divergence between populations. The southwestern United States contains many distinctive plant communities, ranging from woodlands to desert scrub, that are shaped by species adapting to local variation in elevation, precipitation, seasonality, and soils. Given this variation, species occurring across diverse habitats are expected to harbor high genetic diversity and exhibit significant genetic differences associated with environmental variation.

Methodology. Here, we studied the genetic divergence of populations of Xanthisma gracile (Asteraceae) across Arizona using amplified fragment length polymorphisms and evaluated associations …
