Description
A floristic analysis is essential to understanding the current diversity and structure
of community associations of plants in a region. Also, a region’s floristic analysis is key not only to investigating their geographical origin(s) but is necessary to their management and protection as a reservoir of greater biodiversity. With an area of 2,250,000 square kilometers, the country of Saudi Arabia covers almost four-fifths of the Arabian Peninsula. Efforts to document information on the flora of Saudi Arabia began in the 1700s and have resulted in several comprehensive publications over the last 25 years. There is no doubt that these studies have helped both the community of scientific researchers as well as the public to gain knowledge about the number of species, types of plants, and their distribution in Saudi Arabia. However, there has been no effort to use digital technology to make the data contained in various Saudi herbarium collections easily accessible online for research and teaching purposes. This research project aims to develop a “virtual flora” portal for the vascular plants of Saudi Arabia. Based on SEINet and the Symbiota software used to power it, a preliminary website portal was established to begin an effort to make information of Saudi Arabia’s flora available on the world- wide web. Data comprising a total of 12,834 specimens representing 175 families were acquired from different organizations and used to create a database for the designed website. After analyzing the data, the Fabaceae family (“legumes”) was identified as a largest family and chosen for further analysis. This study contributes to help scientific researchers, government workers and the general public to have easy, unlimited access to the plant information for a variety of purposes.

Description
Urbanization has global impacts on ecosystems and transforms landscapes into man-made constructs. As urbanization continues to encroach on landscapes it is important to understand its effects on biodiversity and the long term health of our planet. In terms of species numbers, urban floras can actually be more diverse than their native surroundings and I am specifically interested in the species that have been introduced into these settings, their provenance, and the historical circumstances of how they were established. I collected plants in the alleys of Tempe, Arizona over a 5 month period to get a baseline understanding of the local diversity; then collected data from herbarium records using SEINet http://swbiodiversity.org/seinet/ to trace the origin of the introduced species and the first record of their appearance. I also used on-line information from the City of Tempe to investigate the relationship of land use change, development, and population growth to the introductions of some non-native plants. Finally, I used SIENet records to investigate the relationship of collection intensity throughout the decades to the introductions of some non-native plants. A total of 130 specimen were collected representing 83 different species from 32 different families. Most of the introduced species were from climates similar to Arizona. New occurrence records were spread out over the decades that Tempe has been around, and I was only able to weakly link them to the historical and collection intensity data. Knowing the biodiversity of an area can give clues into the ecosystem services that biodiversity provides, as well as management implications. Additionally, knowing the history of what is out there may give insights into what the biodiversity of the future may look like.

Description
This collection of literary nonfiction essays is lead by the metaphor of cocladogenesis — a unique evolutionary relationship between two lineages that combines coevolution and cospeciation — to suggest that a similar relationship should exist between the subjective and the objective experience, art and science, and the chronicle and the narrative. It is not the singular extreme of either side that results in the advantageously beautiful products of cocladogenesis — it is the constant dialogue between the two factions.
