The data stored in this collection were collected during a series of 3 experiments I conducted between 2013 and 2014 to evaluate the effects of population-level extinction within spatial population networks.
For each experiment, I used experimental protozoan population networks (microcosms) that used the common pond species Paramecium caudatum as the focal organism. Each network contained five populations aligned linearly and connected to one another through a migration corridor (see image files).
The experiments were similar in their basic methods. For example, each experiment consisted of three 10-day periods: pre-extinction, extinction, and reestablishment. In addition, each experiment used 8 networks: four treatment networks and four control networks. During the 10-day extinction period, extinction was maintained on the center population of 4 treatment networks. During the reestablishment period, the center population was allowed to reestablish. The 4 control networks had no extinction imposed.
During each experiment I estimated the density of each population within all networks daily as the mean number of paramecia captured in three 0.25 mL samples. The data included in these files shows these density estimates. All calculations used to assess changes in population abundance and dynamics due to extinction were derived from these density estimates.
Additional background for each of the 3 experiments (e.g., how the experiments differed) can be found in the ReadMe file. Detailed methods and results from each of these experiments are documented in Chapters 3, 4, and 5 of my dissertation (see Dissertation file).
This is the raw data detailing the type of cleistogamy reported within 228 plant genera in 50 families in the scientific literature, as of October 2005. This data underlies the following study:

1855 printing of 1846 copyrighted text. Preface states that while philosophers have studied the senses, few know about the organization of the human voice. Lessons for Dictation and Grammatical Analysis are interesting reading lessons. Exercises in the elements of pronunciation and subject for composition give the orthography of over 10,000 of the most important words in the English language. The Analysis and Classification of the Alphabet has been newly arranged according to the organic construction of the English language. The whole book is intended to be written and studied by the pupil after the dictation and oral explanation by the teacher. The Schultz Archive copy contains the preface, the index, and pages 48 – 49.
1863 printing of 1863 copyrighted text. Author is credited as Superintendent of Public Schools, Oswego, NY, and as author of several texts. An American edition of a text that was in its 14th edition in London in 1855. The first three steps are designed for the first three years of school, the fourth and fifth steps are for students 10 to 14 years old. The object of the lessons is to cultivate the senses, awaken and quicken observation, and to teach the use of the full range of senses. Includes preface by Elizabeth Mayo. Contents is divided into sections based on complexity of object, including sections on metals, natural history, vegetables, textiles, minerals, and manufactured articles. It also includes a list of vocabulary. The Schultz Archive copy is roughly the complete 407 page text.
This "New and Improved Edition" was published in 1894 and copyrighted in 1892. The author is credited as Professor of Language and Literature in the Brooklyn Polytechnic Institute and as the author of several other books. The text claims it is responding to teachers' need for work for pupils to do in illustration of what they have learned. The first section on invention covers sentence structure, forming paragraphs, analysis of subjects, and preparation of frameworks. The second section on qualities of style discusses perspicuity, imagery, energy, wit, pathos, and elegance. The third section on productions breaks up prose into oral (conversation, debates, sermons, etc.) and written (biographies, histories, fiction, letters, etc.). It also discusses poetry by focusing on mission, style, form, and kinds (satiric, epic, dramatic, etc.). Exercises include specific directions for altering or analyzing examples. Excerpts from the work of well known authors are used throughout. The Schultz Archive's copy is roughly the complete text.
