Invasive Plants Of Australian Origin
There are a number of Australian species that have become invasive when introduced into outside Australia or outside Oceania. Animals The Australian magpie has been introduced into New Zealand, where it is considered a pest because of its attacks on humans and a possible effect on the native bird population. The common brushtail possum was introduced to New Zealand to start a fur industry, and spread nationwide. With no natural predators, these omnivores have had severe impacts on the native plants and animals they consume, including the eggs and chicks of nesting birds such as the kererū, tūī, and kākā. They are also a carrier of tuberculosis, which they can spread to livestock. Control of them has been an ongoing project of regional councils, the Department of Conservation, Forest and Bird, and various other wildlife preservation organizations. The boatman fly (''Pogonortalis doclea'') is a dung-feeding platystomatid fly native to Australia that has become invasive ...

Everglades
The Everglades is a natural region of flooded grasslands in the southern portion of the U.S. state of Florida, comprising the southern half of a large drainage basin within the Neotropical realm. The system begins near Orlando with the Kissimmee River, which discharges into the vast but shallow Lake Okeechobee. Water leaving the lake in the wet season forms a slow-moving river wide and over long, flowing southward across a limestone shelf to Florida Bay at the southern end of the state. The Everglades experiences a wide range of weather patterns, from frequent flooding in the wet season to drought in the dry season. Throughout the 20th century, the Everglades suffered significant loss of habitat and environmental degradation. Human habitation in the southern portion of the Florida peninsula dates to 15,000 years ago. Before European colonization, the region was dominated by the native Calusa and Tequesta tribes. With Spanish colonization, both tribes declined g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is harmful to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced species, introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native, though many localities define them as necessarily being non-native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forestry, forest management, nature reserves, regional park, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introd ...

Acacia Saligna
''Acacia saligna'', commonly known by various names including coojong, golden wreath wattle, willow wattle, orange wattle, blue-leafed wattle, Western Australian golden wattle, and, in Africa, Port Jackson willow, is a small tree in the family (biology), family Fabaceae. Native to Australia, it is widely distributed throughout the south west corner of Western Australia, extending north as far as the Murchison River (Western Australia), Murchison River, and east to Israelite Bay, Western Australia, Israelite Bay. The Noongar peoples know the tree as Cujong. Description ''Acacia saligna'' grows as a small, dense, spreading tree with a short trunk and a weeping habit. It grows up to eight metres tall. Like many ''Acacia'' species, it has phyllodes rather than true leaves; these can be up to 25 centimetres long. At the base of each phyllode is a nectary gland, which secretes a sugary fluid. This attracts ants, which are believed to reduce the numbers of leaf-eating insects. The y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Cyclops
''Acacia cyclops'', commonly known as coastal wattle, cyclops wattle, one-eyed wattle, red-eyed wattle, redwreath acacia, western coastal wattle, rooikrans, rooikrans acacia, is a coastal shrub or small tree in the family Fabaceae. Native to Australia, it is distributed along the west coast of Western Australia as far north as Leeman, and along the south coast into South Australia.

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Acacia
''Acacia'', commonly known as wattles or acacias, is a genus of about of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia, but is now reserved for species mainly from Australia, with others from New Guinea, Southeast Asia, and the Indian Ocean. The genus name is Neo-Latin, borrowed from Koine Greek (), a term used in antiquity to describe a preparation extracted from '' Vachellia nilotica'', the original type species. Several species of ''Acacia'' have been introduced to various parts of the world, and two million hectares of commercial plantations have been established. Description Plants in the genus ''Acacia'' are shrubs or trees with bipinnate leaves, the mature leaves sometimes reduced to phyllodes or rarely absent. There are 2 small stipules at the base of the leaf, but sometimes fall off as the leaf matures. The flowers are borne in spik ...

Biological Control
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insects play an important part in limiting the densities of potential pests. Biological control agents such as these include predators, parasitoids, pathogens, and co ...
