INTRODUCTION TO MARINE BIOLOGY sparks curiosity about the marine world and provides an understanding of the process of science. Taking an ecological approach and intended for non-science majors, the text provides succinct coverage of the content while the photos and art clearly illustrate key concepts. Studying is made easy with phonetic pronunciations, a running glossary of key terms, end-of-chapter questions, and suggestions for further reading at the end of each chapter. The open look and feel of INTRODUCTION TO MARINE BIOLOGY and the enhanced art program convey the beauty and awe of life in the ocean. Twenty spectacular photos open the chapters, piquing the motivation and attention of students, and over 60 photos and pieces of art are new or redesigned.

structure within which an original cell divides by meiosis to produce four daughter cells, each of which then divides once by mitosis, resulting in a total of eight ascospores. (a) GLOSSARY reasons, some mycologists argue that marine fungi have evolved from terrestrial and freshwater fungi, probably multiple times. Marine fungi can also be classified on the basis of the material on which they are found. By far, the most diverse group of marine fungi lives on or in wood of terrestrial origin

can be drawn from that principle (deductive reasoning) and those points tested. Scientists use an organized, commonsense approach to their work that begins with making observations of the natural world. On the basis of these observations, the scientist asks questions, proposes hypotheses, designs experiments to test the hypotheses, gathers results, and draws conclusions. This orderly pattern of gathering and analyzing information is called the scientific method. The scientific method represents

events, or it may be more complex and propose a model for the way a particular process may work. There can be more than one method of formulating a hypothesis. Insights can arise from accident and intuition as well as from methodical observations. Step 3: Using Deductive Reasoning to Design Experiments A hypothesis is an explanation for observed events that can be experimentally tested. Inductive reasoning is a process of reasoning whereby a general explanation is derived from a series of

portion of the mantle just beneath it. The asthenosphere lies beneath the lithosphere and is able to flow under stress. G LO S S A R Y Figure Because the crust is the most easily accessible portion of the earth, more is known about it than the other layers. The continental crust is thicker and slightly less dense than the oceanic crust and is mainly composed of granite, which contains mostly lightweight silicate-rich minerals, such as quartz and feldspar. The oceanic crust, by comparison, is

species was defined as a group of organisms with an observable set of characteristics that was different from other, similar organisms. Today a species is defined as one or more populations of potentially interbreeding organisms that are reproductively isolated from other such groups. New species may form when environmental or genetic changes cause portions of a population to become reproductively isolated from the rest of the group and natural selection acts independently on them.
