At the beginning of human history, we had to satisfy our energy needs (for food, heat and movement) by using our own muscle power and gathering or hunting naturally available plants, animals and wood. Each stage in the evolution of human society (the development of farming, domestication of animals, harnessing of wind and water power)…
As the human population has grown, and our use of resources has increased, we have destroyed the habitat of many species. A biodiversity crisis has developed. The Red List of Threatened Species, compiled by the World Conservation Union, lists 16,913 species as threatened with extinction. Conservation biology—the scientific study of phenomena that affect the maintenance,…
The term ecosystem was first used by Tansley (1935) to refer to all the components of an ecological system, biotic and abiotic, that influence the flow of energy and elements. The ecosystem concept integrates ecology with other disciplines such as geochemistry, hydrology, and atmospheric science. Primary production is the chemical energy generated by autotrophs during…
Historically, honey has been used by humans to treat a variety of ailments through topical application, but only recently have the antiseptic and antibacterial properties of honey been chemically explained. Hydrogen peroxide is formed in a slow-release manner by the enzyme glucose oxidase present in honey. It becomes active only when honey is diluted, requires…
Positive interactions occur when neither species is harmed and the benefits of the interaction are greater than the costs for at least one species. Facilitation is a synonym for positive interactions. Mutualism: Mutually beneficial interaction between individuals of two species (+/+). Commensalism: Individuals of one species benefit, while individuals of the other species do not…
Symbionts: Organisms that live in or on other organisms. More than half of Earth’s species are symbionts. Our own bodies can be a home to many other species. A parasite consumes the tissues or body fluids of the organism on which it lives (the host). Enslaving parasite: control the host in a way to aid…

Human Population Growth: A Case Study Humans have a large impact on the global environment: Our population has grown explosively, along with our use of energy and resources. Human population reached 6.8 billion in 2010, more than double the number of people in 1960. Our use of energy and resources has grown even more rapidly.…
Distribution: Geographic area where individuals of a species occur. Abundance: Number of individuals in a given area. Ecologists try to understand what factors determine the distribution and abundance of species. Populations are dynamic—distribution and abundance can change over time and space. ***Understanding the factors that influence these dynamics helps us manage populations for harvest or…
An organism’s life history is a record of events relating to its growth, development, reproduction, and survival. Life history characteristics include: Age and size at sexual maturity. Amount and timing of reproduction. Survival and mortality rates. Life History Diversity Individuals within a species show variation in life history traits due to genetic variation or environmental…
Humans have a large impact on the environment—pollution, land use change, climate change, etc. We are just beginning to realize that we also cause evolutionary change, and the consequences of this. Ecology and evolution are strongly interconnected. What Is Evolution? Evolution can be viewed as genetic change over time or as a process of descent…
