Terms in this set (...)

Adaptive Management
The use of the experimental method in trying several promising types of management to find out what works best. p1244
Biodiversity Crisis
The current rapid decline in the variety of life on Earth, largely due to the effects of human culture. p1224
Biodiversity Hot Spot
A relatively small area with an exceptional concentration of endemic species and a large number of endangered and threatened species. p1239
The use of living organisms to detoxify and restore polluted and degraded ecosystems. p1242
Conservation Biology
The integrated study of ecology, evolutionary biology, physiology, molecular biology, genetics, and behavioral biology in an effort to sustain biological diversity at all levels. p1224
Declining-Population Approach
An approach focusing on threatened and endangered populations even if they are far greater than minimum viable size. p1236
Ecosystem Services
Function performed by natural ecosystems that directly or indirectly benefits humans. p1227
Effective Population Size (Ne)
An estimate of the size of a population based on the numbers of females and males that successfully breed; generally smaller than the total population. A more meaningful estimate of MVP factoring in the breeding potential of the population based on sex ratio of breeding individuals; Ne = (4NfNm)/(Nf + Nm) where Nf and Nm = females and males that successfully breed. p1233
Endangered Species
A species that is in danger of extinction throughout all or a significant portion of its range. p1225
Extinction Vortex
A downward population spiral in which positive-feedback loops of inbreeding and genetic drift cause a small population to shrink, and unless reversed, become extinct. p1232
Introduced Species
A species moved by humans, either intentionally or accidentally, from its native location to a new geographic region; also called an exotic species. p1229
Several different primarily terrestrial ecosystems linked by exchange of energy, materials, and organisms. p1238
Landscape Ecology
The study of past, present, and future patterns of landscape use, as well as ecosystem management and the biodiversity of interaction ecosystems. p1238
Minimum Viable Population (MVP)
The smallest population size at which a species is able to sustain its numbers and survive. p1233
Movement Corridor
A series of small clumps or a narrow strip of quality habitat (useable by organisms) that connects otherwise isolated patches of quality habitat. p1239
Population Viability Analysis (PVA)
A method of predicting whether or not a population will persist. p1233
Restoration Ecology
A goal-directed science that applies ecological principles in an effort to return degraded ecosystems to conditions as similar as possible other natural, predegraded state. p1242
Small-Population Approach
An approach that studies the processes that can cause very small populations to finally become extinct. A population's smallness itself drives the species to extinction because of the extinction vortex p1232
Sustainable Biosphere Initiative
An research agenda in which the goal is to define and acquire the basic ecology information necessary for the intelligent and responsible development , management, and conservation of Earth's resources. Endorsed by the Ecological Society of America. p1244
Threatened Species
A species that is considered likely to become endangered in the foreseeable future. p1225
Zoned Reserve
Extensive regions of land that includes one or more areas undisturbed by humans surrounded by lands that have been changed by human activity are used for economic gain. p1241
Sustainable Development
The long-term prosperity of human societies and the ecosystems that support them. p1244
Harvesting by humans of wild plants or animals at rates exceeding the ability of populations of those species to rebound. p1231
Biological Augmentation
An approach to restoration ecology that uses organisms to add essential materials to a degraded ecosystem. p1243
a human sense of connection to nature and other forms of life. p1244
