Marine Biology: An Ecological Approach
Appropriate for undergraduate majors and graduate students in marine biology and marine ecology, Marine Biology: An Ecological Approach emphasizes the ecological principles that govern marine life throughout all environments within the world's oceans. Its unique ecological approach adds real-world relevance by exploring how organisms interact within their individual ecosystems. The text is organized by habitat and each habitat receives detailed, in-depth coverage, giving instructors flexibility to focus on their particular areas of interest. The Fifth Edition is fully updated with the latest research data and topics, including expanded coverage of the human impact on oceans, oceanic dead zones, and coral reefs. In addition to Nybakken's engaging writing style, the text now offers enhanced pedagogy with new end-of-chapter summaries, a new four-color design to complement the art program, an art CD-ROM for instructors, and a text specific Companion Web site.

Into each is placed the same volume of seawater taken from the body of water for
which you wish to estimate productivity. The water contains the naturally
occurring phytoplankton and zooplankton organisms. The oxygen content of the
more oxygen to be held in the body. This oxygen capacity is increased further, as
Scholander (1940) notes, because marine mammals also possess a higher
oxygen capacity per unit volume of blood than terrestrial mammals (40 ml O2/100
Oxygen Even though the deep ocean waters are far from a source of oxygen
replenishment, either by interaction with the atmosphere or through production by
autotrophs, there are essentially no abyssal or hadal areas that lack sufficient ...
