Native peoples in the Americas did not have many domesticated animals and thus germs and antibodies did not coevolve here and they never developed resistance. Humans not native to Americas our primate ancestors, chimps, gorillas, etc never lived here ; they crossed over land bridge from Asia in small groups, and whatever diseases might have been in population died out without enough hosts during artic crossing. Columbus reintroduced pathogens that had been devastating to humans in the rest of the world--smallpox, measles, whooping cough, bubonic plague, malaria, yellow fever, dysentery.
Indian River Lagoon Species Inventory Non-Native and Invasive Species Non-native species are species that have been introduced into new areas that have not historically been part of their native range.
In contrast, native species are species that have historically occurred as part of an ecosystem in a specific location. Native species are also called indigenous species. Introduction is defined by Krueger and May as the transfer by humans of an organism outside its native range.
Plants and animals have been transported by humans and introduced into new areas for many centuries. Some of these introductions have been intentional, although a great many have not.
Intentional introductions are often for purposes of livestock or agricultural production, e. The Australian spotted jellyfish, Phyllorhiza punctata, is a non-native organism that has been collected from the Indian River Lagoon Many intentional introductions of cultivated stocks and crops have, of course, been of great economic benefit.
Hundreds of nonindigenous plants and animals have been introduced to Florida in the five centuries since the arrival of the first European settlers and many of these have greatly benefited man.
For example, the cultivated plants of genus Citrus originated in tropical to subtropical southeast Asia, India, and the Near East and were introduced to Florida and the New World by Spanish explorer Ponce de Leon in The various modern hybrid citrus cultivars-including the world-famous "Indian River Citrus" varieties-now represent a billion-dollar industry in the state.
The exotic zebra mussel, Dreissema polymorpha, is a highly invasive species that has caused problems in the U.
Great Lakes and elsewhere. Unfortunately, not all species introductions have proven beneficial. Whether intentionally released to the environment, intentionally introduced and then accidentally released, or introduced entirely by accident, the negative ecological and economic impacts of exotic species introduction are substantial.
Very often, the invaders go largely unnoticed until populations have grown and spread to a point where eradication is difficult and costly, or even impossible.
The most infamous such invasion in recent memory in North America is that of the zebra mussel Dreissena polymorpha in the Great Lakes. In Florida, the introduction and spread of the green mussel Perna viridis in Tampa Bay is a prime example of an exotic introduction that has had substantial ecological and economic impacts.
What Makes a Successful Invader? Exotic species have the potential to become invasive when they are released into a new environment. Invasive nonindigenous species are those species whose introduction causes, or is likely to cause, significant economic or environmental harm.
Not all non-native species become invasive when released to novel systems. In fact, the majority of individual introduction events are believed to be of little consequence, with the introduced individuals failing to lead to established populations. In other cases, the introduced species does become established but, for reasons not entirely understood, its presence causes little or no ecological or economic impact.
Freed from natural competitors, Old World climbing fern, Lygodium microphyllum, quickly invades and overgrows a native Florida plant community. Nevertheless, any species removed from its native range and introduced to a new area has the potential to become an invasive species.Chapter 13 mc.
STUDY. Which of the following was a reason that Portugal, Spain, France, and Britain were the first to expand in the new world?
These lands were on the Atlantic coast and were closer to the Americas.
What did the introduction of domesticated animals into the Americas make possible? The motivation at the time was a sense that introducing these species of (mainly from Europe) in new areas while also bringing exotic and useful foreign plants and animals into the European society established a branch in Algeria as well as the Jardin d' Acclimatation in Paris in to showcase not just new animals and plants.
Introduced Wild Animals in Australia Rabies occurs in most parts of the world and is prevalent in South-East Asia and Indonesia. There is a serious risk it could enter Australia through the illegal importation of an infected dog.
Consequently, there were many unforseen results from introducing a host of new animal species into Australia. (CAP) affect live animal flows into the Netherlands.
The focus lies on imports of bovine animals from the new member states of the EU (NMS) in the years up to What did Europeans see when they looked at the New World and the Native Americans?
Collected by Peter Pappas mtb15.com Document 1: From a letter by Christopher Columbus some making holes with sticks, into which the others drop the seeds of beans or maize.
Then. Country X is moving its capital to sever ties to its colonial roots. The ruling faction is less concerned about efficiency of buildings than about reflecting the capital city's new direction and raising its status among world cities.
However, this country of the periphery must minimize building costs.
