All organisms are linked to their surroundings. The survival of an organism thus depends upon its surroundings. These surroundings of an organism constitute its (are called as - delete) environment. Any change in the surroundings/environment affects the growth and survival of living organisms to a significant extent. Nutrients and energy get distributed among various living components present in a particular environment. Ecology is the study of the relationship of organisms i.e. plants, animals, microorganisms with their surroundings (environment). Ecological studies deal with the relationships of organisms with their environment. The present unit provides information about basic concepts in ecology. Expected Learning Outcomes After the study of this Unit, you should be able to define various terms used in ecology (environment, population, community, ecosystem and ecosphere), 7 Block 1 Ecology and Ecological Factors describe subdivisions of ecology, outline differences between natural and man-made environment, describe components of the ecosystem, enlist characteristics of the community, enumerate knowledge about recent developments in the field of ecology, and discuss the interrelationships between ecology and other disciplines of biology. 1.2 WHAT IS ECOLOGY? Hanns Reiter (1868) gave the concept of ecology. -

The notable American resistance to educated professionalism is explored and placed in its historic, multinational framework. Throughout, the limitations of various theoretical approaches to analyzing professionalism are addressed and more realistic methods of defining professionalism in context are offered. The field of school librarianship is examined as a domain where professionalism and appropriate LIS education are sustained to some degree in law and regulation but face challenges at the system and building level. -

Petersen Department of Ecology & Evolutionary Biology, University of Tennessee Knoxville, TN 37919-1100 Correspondence to: [email protected] Abstract—The Morrill Act of 1862 afforded the US states the opportunity to found state colleges with agriculture as part of their mission—the so-called “land-grant colleges.” The Hatch Act of 1887 gave the same opportunity for agricultural experiment stations as functions of the land-grant colleges, and the “third Morrill Act” (the Smith-Lever Act) of 1914 added an extension dimension to the experiment stations. Overall, the end of the 19th century and the first quarter of the 20th was a time for growing appreciation for, and growth of institutional education in the natural sciences, especially botany and its specialties, mycology, and phytopathology. This paper outlines a particular genealogy of mycologists and plant pathologists representative of this era. Professor Albert Nelson Prentiss, first of Michigan State then of Cornell, Professor William Russel Dudley of Cornell and Stanford, Professor Mason Blanchard Thomas of Wabash College, and Professor Herbert Hice Whetzel of Cornell Plant Pathology were major players in the scenario. The supporting cast, the students selected, trained, and guided by these men, was legion, a few of whom are briefly traced here. Key words—“New Botany,” European influence, agrarian roots Chapter 1.

Dawson: Geologist and Educator Dawson’S Interest in Natural History Began Early
INTRODUCTION Bernard of Chartres, an 11th–12th century philosopher and teacher, said that we are like dwarfs on the shoulders of giants, so that we can see more than they and for a greater distance, not by any virtue of our own but because we are carried high and raised aloft by their stature. All of us have our geological heroes, those giants on whose shoulders we stand. To encourage recognition of these luminaries and to provide inspiration for students and young professionals, the GSA History of Geology Division presents Rock Stars, brief pro- files of our geological giants. If you have any comments on profiles, please contact Robert N. Ginsburg, University of Miami, RSMAS/MGG, 4600 Rickenbacker Causeway, Miami, FL 33149-1098, e-mail: [email protected]. —Robert N.
