Exam 1: Introduction to Ecology Historical Foundations and Developing Frontiers

Norris and colleagues found that warblers using different habitats did not have different carbon isotopes in the tissues.

An ecosystem is defined as

Populations changing genetically over time in response to variation in its environment is termed ____________.

Physiological ecologists study

Ecology can be defined as the study of the impact of human activity on the environment.

Margaret Davis' studies on lake pollen sediments indicate that the forests of eastern North America did not change with the changing climate.

Robert MacArthur's observations on the Warblers of North America indicate that they

____________ are aerial plants obtaining nutrient from trapped organic matter.

According to Margaret Davis,who studied pollen contained within lake sediments,the vegetation landscape of the Appalachian Mountains from 12,000 years ago until approximately 100 years ago changed as follows:

Ecology is a modern science of which ancient man had no knowledge.

The 'scientific method' includes

The pioneering work of Nalini Nadkarni in rain forest ecology revealed that

A population can be defined as

Which of the following levels of organization is/are correctly ordered?

What is ecology?

Stable isotope analysis uses variation in element masses to better understand ecological phenomena.

Temperate and tropical rain forest trees extract nutrients from epiphytic mats.

Population ecologists do not study

Field studies and laboratory studies are mutually exclusive.

Ecologists study
