Ecological imperialism
concept of foreign species aiding colonization by disrupting local ecology

Ecological imperialism is an explanatory concept, introduced by Alfred Crosby, that points out the contribution of European biological species such as animals, plants and pathogens in the success of European colonists. Crosby wrote Ecological Imperialism: The Biological Expansion of Europe, 900-1900 in 1986. He used the term "Neo-Europes" to describe the places colonized and conquered by Europeans.
Examples for Crosby's concept
In 1607, a group of colonists led by Captain John Smith arrived in North America and established the Jamestown colony in Virginia. Though at first it seemed the colonists would not survive the harsh conditions of the New World, ultimately it was the natives who could not survive the diseases of the Old World. "The colonizers brought along plants and animals new to the Americas, some by design and others by accident. Determined to farm in a European manner, the colonists introduced their domesticated livestock—honeybees, pigs, horses, mules, sheep, and cattle—and their domesticated plants, including wheat, barley, rye, oats, grasses, and grapevines. But the colonists also inadvertently carried pathogens, weeds, and rats." The introduction of these foreign species upset the balance of native species and severely hurt the way of life of the native population.
The first major smallpox outbreak among natives was between 1616 and 1619 in Massachusetts. Native Americans had never seen a disease like this, and it wiped out entire settlements in nations such as the Abenaki, the Pawtucket, and the Wampanoag.
This brief starts where responsible research should: with the source description of “Ecological imperialism” as concept of foreign species aiding colonization by disrupting local ecology. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as concept of foreign species aiding colonization by disrupting local ecology. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 5, 2026. The linked authority identifier is Q17074195. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1900, 1986, 1607 and 1616.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
