Butler's Corella
Butler's corella (''Cacatua pastinator butleri'') is a medium-sized white cockatoo endemic to Western Australia. It is one of two subspecies of the western corella.Anon. (2007). ''Butler’s Corella''. (Fauna Note No.19). Department of Environment and Conservation, Western Australi Description Butler's corella has mainly white plumage with a distinct white crest. The undersides of the wings and tail are pale yellow. The feathers between the eye and beak are deep salmon-pink, as are the bases of the feathers on the head and underparts. The eye is surrounded by a broad grey-blue eye-ring. The white plumage is often stained with soil because of the birds’ foraging activities. The corellas range from 40–48 cm in length and 600–750 g in weight. They are very similar in appearance to Muir's corella, the nominate subspecies of the western corella. Distribution and habitat Butler's corella is found in the northern and central wheatbelt of south-west Western Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julian Ralph Ford
Dr Julian Ralph Ford (3 November 1932 – 31 January 1987) was an Australian chemist and ornithologist. He was born in Perth and graduated in chemistry from the University of Western Australia in 1955. He worked for the Shell Oil Company until 1960 when he went on to a career of lecturing on chemistry, first at the Perth Technical College and then the Western Australian Institute of Technology. Ford's early ornithological work included a study of yellow-rumped thornbills. Later he focused on the speciation of birds in inland Australia, making several expeditions in the course of his research. He also discovered that the wedgebill comprised two separate species, the chirruping and chiming wedgebills. He was a member of the Royal Australasian Ornithologists Union (RAOU) and served on its Taxonomic Advisory Committee. He also contributed numerous papers to its journal, the ''Emu''. In 1983 he was awarded a PhD by the University of Western Australia for his ornithological studi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corm
A corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat ( perennation). The word ''cormous'' usually means plants that grow from corms, parallel to the terms ''tuberous'' and ''bulbous'' to describe plants growing from tubers and bulbs. Structure A corm consists of one or more internodes with at least one growing point, generally with protective leaves modified into skins or tunics. The tunic of a corm forms from dead petiole sheaths—remnants of leaves produced in previous years. They act as a covering, protecting the corm from insects, digging animals, flooding, and water loss. The tunics of some species are thin, dry, and papery, at least in young plants, however, in some families, such as ''Iridaceae'', the tunic of a mature corm can be formidable protection. For example, some of the larger species of '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Playing Field
Play is a range of Motivation#Incentive theories: intrinsic and extrinsic motivation, intrinsically motivated activities done for recreational pleasure and enjoyment. Play is commonly associated with children and juvenile-level activities, but may be engaged in at any life stage, and among other higher-functioning animals as well, most notably mammals and birds. Many prominent researchers in the field of psychology, including Melanie Klein, Jean Piaget, William James, Sigmund Freud, Carl Jung and Lev Vygotsky have erroneously viewed play as confined to the human species, believing play was important for human development and using different research methods to prove their theories. Play is often interpreted as frivolous; yet the player can be intently focused on their objective, particularly when play is structured and goal-oriented, as in a game. Accordingly, play can range from relaxed, free-spirited and spontaneous through frivolous to planned or even compulsive. Play is not ...

Lawn
A lawn is an area of soil-covered land planted with grasses and other durable plants such as clover which are maintained at a short height with a lawnmower (or sometimes grazing animals) and used for aesthetic and recreational purposes. Lawns are usually composed only of grass species, subject to weed and pest control, maintained in a green color (e.g., by watering), and are regularly mowed to ensure an acceptable length. Lawns are used around houses, apartments, commercial buildings and offices. Many city parks also have large lawn areas. In recreational contexts, the specialised names turf, pitch, field or green may be used, depending on the sport and the continent. The term "lawn", referring to a managed grass space, dates to at least than the 16th century. With suburban expansion, the lawn has become culturally ingrained in some areas of the world as part of the desired household aesthetic.Robbins, PaulLawn People: How Grasses, Weeds, and Chemicals Make Us Who We A ...

Threatened
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species * Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Salmonophloia
''Eucalyptus salmonophloia'', commonly known as salmon gum, wurak or weerluk or woonert or marrlinja. is a species of small to medium-sized tree that is endemic to Western Australia. It has smooth bark, narrow lance-shaped to curved adult leaves, flower buds in groups of between nine and thirteen, creamy white flowers and hemispherical fruit. Description ''Eucalyptus salmonophloia'' is a tree that typically grows to a height of and a width of and does not form a lignotuber. The tree is quite shallow rooting with roots spreading radially over quite a distance from the base of the tree although the roots are deep enough to make the tree drought resistant. Taller trees can have trunks that are up to in length. Epicormic buds can be produced further up the stem allowing the tree to resprout after fire. It is an erect tree in form and has an umbrella shaped canopy. The crown of the tree can spread as wide as and provide shade over a wide area. It has smooth pale grey-silver bark ...

Eucalyptus Wandoo
''Eucalyptus wandoo'', commonly known as wandoo, dooto, warrnt or wornt, is a small to medium-sized tree that is endemic to the southwest of Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of nine to seventeen, white flowers and conical to cylindrical fruit. It is one of a number of similar ''Eucalyptus'' species known as ''wandoo''. Description ''Eucalyptus wandoo'' is a tree that typically grows to a height of and sometimes to and has a diameter of and where the bole or trunk that is usually straight and composes 50% to 65% of the total height of the tree. ''E.wandoo'' can have long lifetimes with some trees is excess of 150 years of age. It forms a lignotuber, the woody tuber that begins to develop near the base of seedlings but can become huge in older trees and contains embedded epicormic buds that allow the plant to regenerate following destruction of the crown following fire or drought.

Tree Hollows
A tree hollow or tree hole is a semi-enclosed cavity which has naturally formed in the trunk or branch of a tree. They are found mainly in old trees, whether living or not. Hollows form in many species of trees, and are a prominent feature of natural forests and woodlands, and act as a resource or habitat for a number of vertebrate and invertebrate animals. Hollows may form as the result of physiological stress from natural forces causing the excavating and exposure of the heartwood. Forces may include wind, fire, heat, lightning, rain, attack from insects (such as ants or beetles), bacteria, or fungi. Also, trees may self-prune, dropping lower branches as they reach maturity, exposing the area where the branch was attached. Many animals further develop the hollows using instruments such as their beak, teeth or claws. The size of hollows may depend on the age of the tree. For example, eucalypts develop hollows at all ages, but only from when the trees are 120 years old do they f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are im ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romulea Rosea
''Romulea rosea'' is a herbaceous perennial plant in the family Iridaceae. It is a small plant, usually less than 20 cm high, with grass-like leaves.
