Tasman National Park
The Tasman National Park is a national park in eastern Tasmania, Australia, approximately east of Hobart. The park is situated on part of both the Forestier and Tasman peninsulas and encompasses all of Tasman Island. History Whaling activity took place in the 1830s and 1840s. The park was proclaimed under the Regional Forest Agreement on 30 April 1999. The Tasman Island Lighthouse (constructed in 1906) is located on Tasman Island, which is part of the park. This lighthouse and weather station has been unmanned since 1977.Brothers, Nigel; Pemberton, David; Pryor, Helen; & Halley, Vanessa. (2001).

Fortescue Bay
Fortescue Bay or Baje Dolomien is a bay in southeast Tasmania, Australia. It is located east of Port Arthur, Tasmania, and makes up part of Tasman National Park. Within the bay are two smaller nested bays, Canoe Bay and Bivouac Bay. History Timber mill During the early 1900s, a timber mill was started at Fortescue Bay by G. Albury and Turner Brothers. At the beginning of the 1920s, the Gathercole Brothers company began advertising for men to work at their mill. It is possible that the Gathercole Brothers carried on operation of the mill owned by G. Albury and Turner Brothers, as they owned several mills around Port Arthur. Fish works Until the early 1970s, Canoe Bay played host to a fish works. Shipwreck On 1 July 1953, a dredge named for William Pitt was towed from Hobart to Fortescue Bay and scuttled in the mouth of Canoe Bay at the request of the Minister for Agricultural and Sea Fisheries. The dredge was scuttled to act as a breakwater for the many fishing vessels usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Pillar
Cape Pillar is a rural locality in the local government area (LGA) of Tasman in the South-east LGA region of Tasmania. The locality is about south-east of the town of Nubeena.

South-east Tasmania Important Bird Area
The South-east Tasmania Important Bird Area encompasses much of the land retaining forest and woodland habitats, suitable for breeding swift parrots and forty-spotted pardalotes, from Orford to Recherche Bay in south-eastern Tasmania, Australia. Features and location This large Important Bird Area (IBA) comprises wet and dry eucalypt forests containing old growth Tasmanian blue gums or black gums, and grassy manna gum woodlands, as well as suburban residential centres and farmland where they retain large flowering, and adjacent hollow-bearing, trees. Key tracts of forest within the IBA include Wielangta, the Meehan and Wellington Ranges, and the Tasman Peninsula. The area has been identified by BirdLife International as an IBA because it contains almost all the breeding habitat of the endangered swift parrot on the Tasmanian mainland, several populations of the endangered forty-spotted pardalote, as well as good numbers of flame and pink robins, striated fieldwrens a ...

Little Penguin
The little penguin (''Eudyptula minor'') is a species of penguin from New Zealand. They are commonly known as little blue penguins or blue penguins owing to their slate-blue plumage and are also known by their Māori name . The Australian little penguin (''Eudyptula novaehollandiae'') from Australia and the Otago region of New Zealand is considered a separate species by a 2016 study and a 2019 study. Taxonomy The little penguin was first described by German naturalist Johann Reinhold Forster in 1781. Several subspecies are known, but a precise classification of these is still a matter of dispute. The holotypes of the subspecies ''E. m. variabilis'' and ''Eudyptula minor chathamensis'' are in the collection of the Museum of New Zealand Te Papa Tongarewa. The white-flippered penguin (''E. m. albosignata'' or ''E. m. minor morpha albosignata'') is currently considered by most taxonomists to be a colour morph or subspecies of ''Eudyptula minor.'' In 2008, Shirihai treated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Fur Seal
The brown fur seal (''Arctocephalus pusillus''), also known as the Cape fur seal, South African fur seal and Australian fur seal, is a species of fur seal. Description The brown fur seal is the largest and most robust member of the fur seals. It has a large and broad head with a pointed snout that may be flat or turned up slightly. They have external ear flaps (pinnae) and their whiskers (vibrissae) are long, and may extend backward past the pinnae, especially in adult males. The fore flippers are covered with sparse hair over about three-quarters of their length. The hind flippers are short relative to the large body, with short, fleshy tips on the digits. The size and weight of the brown fur seal depends on the subspecies. The Southern African subspecies is on average slightly larger than the Australian subspecies. Males of the African subspecies (''A. p. pusillus'') are in length on average and weigh . Females are smaller, averaging in length and typically weighing .Kin ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing ...

Macrocystis Pyrifera
''Macrocystis pyrifera'', commonly known as giant kelp or bladder kelp, is a species of kelp (large brown algae), and one of four species in the genus '' Macrocystis''. Despite its appearance, it is not a plant; it is a heterokont. Giant kelp is common along the coast of the northeastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, Australia, and New Zealand. Individual algae may grow to more than long at a rate of as much as per day. Giant kelp grows in dense stands known as kelp forests, which are home to many marine animals that depend on the algae for food or shelter. The primary commercial product obtained from giant kelp is alginate, but humans also harvest this species on a limited basis for use directly as food, as it is rich in iodine, potassium, and other minerals. It can be used in cooking in many of the ways other sea vegetables are used, and particularly serves to add fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allocasuarina Crassa
''Allocasuarina crassa'', commonly known as Cape Pillar sheoak, is a species of flowering plant in the family Casuarinaceae and is endemic to a small area in far south-eastern Tasmania. It is a low shrub to small tree that is monoecious or dioecious, with spreading to erect branchlets up to long, the leaves reduced to scales in whorls of seven to ten, the fruiting cones long containing winged seeds (samaras) long. Description ''Allocasuarina crassa'' is a dioecious or monoecious shrub that typically grows to a height of , or sometimes a small tree to , and has smooth bark. Its branchlets are spreading to more or less erect, up to long, the leaves reduced to erect, scale-like teeth long, arranged in whorls of seven to ten around the branchlets. The sections of branchlet between the leaf whorls (the "articles") are long and wide and the furrows along the branchlets are hairy. Male flowers are arranged in spikes about long, the anthers long. Female cones are cylindrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent wood, woody stems above ground. This broad category of plants includes many perennial plant, perennials, and nearly all Annual plant, annuals and Biennial plant, biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. Glossary of botanical terms#scarious, scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentatio ...

Parasitism
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the hos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
