The Silurian is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at 443.8 million years ago (Mya), to the beginning of the Devonian Period, 419.2 Mya. The Silurian is the third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out.
Berberidopsidales is an order of Southern Hemisphere woody flowering plants. The name is newly accepted in the APG III system of plant taxonomy. APG II system, of 2003, mentions the possibility of recognizing the order, as comprising the families Berberidopsidaceae and Aextoxicaceae. However, APG II left the families unplaced as to order, assigning them to the clade core eudicots. The APG III system of 2009 formally recognized the order.
Robinia is a genus of flowering plants in the family Fabaceae, tribe Robinieae, native to North America. Commonly known as locusts, they are deciduous trees and shrubs growing 4–25 metres (13–82 ft) tall. The leaves are pinnate with 7–21 oval leaflets. The flowers are white or pink, in usually pendulous racemes. Many species have thorny shoots, and several have sticky hairs on the shoots.
Arbutus is a genus of 12 accepted species of flowering plants in the family Ericaceae, native to temperate regions of the Mediterranean, western Europe, the Canary Islands and North America, and commonly called madrones or strawberry trees. The name Arbutus was taken by taxonomists from Latin, where it referred to the species now designated Arbutus unedo.
Lentibulariaceae is a family of carnivorous plants containing three genera: Genlisea, the corkscrew plants; Pinguicula, the butterworts; and Utricularia, the bladderworts.
Zosteraceae is a family of marine perennial flowering plants found in temperate and subtropical coastal waters, with the highest diversity located around Korea and Japan. Most seagrasses complete their entire life cycle under water, having filamentous pollen especially adapted to dispersion in an aquatic environment and ribbon-like leaves that lack stomata. Seagrasses are herbaceous and have prominent creeping rhizomes. A distinctive characteristic of the family is the presence of characteristic retinacules, which are present in all species except members of Zostera subgenus Zostera.
Cunoniaceae is a family of 27 genera and about 335 species of woody plants in the order Oxalidales, mostly found in the tropical and wet temperate regions of the Southern Hemisphere. The greatest diversity of genera are in Australia and Tasmania, New Guinea, and New Caledonia. The family is also present in Central America, South America, the Caribbean, Malesia, the islands of the South Pacific, Madagascar and surrounding islands. The family is absent from mainland Asia except from Peninsular Malaysia, and almost absent from mainland Africa apart from two species from Southern Africa. Several of the genera have remarkable disjunct ranges, found on more than one continent, e.g. Cunonia, EucryphiaWeinmannia.
Streptophyta, informally the streptophytes, is a clade of plants. The composition of the clade varies considerably between authors, but the definition employed here includes land plants and all green algae except the Chlorophyta and the more basal Prasinodermophyta.
A school counselor is a certified/licensed professional that provides academic, career, college readiness, and social-emotional support for all students. There are school counselor positions within each level of schooling. By developing and following a school counseling program, school counselors are able to provide students of all ages with the appropriate support and guidance needed for overall success.
Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include Commelina (dayflowers) and Tradescantia (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms.
Acacia pycnantha, most commonly known as the golden wattle, is a tree of the family Fabaceae. It grows to a height of 8 metres and has phyllodes instead of true leaves. The profuse fragrant, golden flowers appear in late winter and spring, followed by long seed pods. Explorer Thomas Mitchell collected the type specimen, from which George Bentham wrote the species description in 1842. The species is native to southeastern Australia as an understorey plant in eucalyptus forest. Plants are cross-pollinated by several species of honeyeater and thornbill, which visit nectaries on the phyllodes and brush against flowers, transferring pollen between them.
Begoniaceae is a family of flowering plants with two genera and about 2040 species occurring in the subtropics and tropics of both the New World and Old World. All but one of the species are in the genus Begonia. There have been many recent discoveries of species in the genus Begonia, such as Begonia truncatifolia which is endemic to San Vincente, Palawan. B. truncatifolia is smaller than other species of the genus Begonia and this new species is proposed Critically Endangered by standards set by the IUCN. The only other genus in the family, Hillebrandia, is endemic to the Hawaiian Islands and has a single species. Phylogenetic work supports Hillebrandia as the sister taxon to the rest of the family. The genus Symbegonia was reduced to a section of Begonia in 2003, as molecular phylogenies had shown it to be derived from within that genus. Members of the genus Begonia are well-known and popular houseplants.
Berberidopsis is a genus of flowering plants in the small family Berberidopsidaceae.
Berberidopsidaceae is a family of flowering plants. Such a family has only recently been recognized by more than a few taxonomists: the plants involved have often been treated as belonging to family Flacourtiaceae.
Harpullia is a genus of about 27 species of small to medium-sized rainforest trees from the family Sapindaceae. They have a wide distribution ranging from India eastwards through Malesia, Papuasia and Australasia to the Pacific Islands. They grow naturally usually in or on the margins of rainforests or associated vegetation. Plants in the genus Harpullia are usually dioecious shrubs or trees covered with simple or star-shaped hairs. The leaves are paripinnate and the flowers are usually arranged in leaf axils, usually with 5 petals, 5 to 8 stamens and a 2-locular ovary. The fruit is a 2-lobed capsule.
The yellow pond turtle, is a medium-sized, semiaquatic turtle in the family Geoemydidae. This species has a characteristic broad yellow stripe extending behind the eye and down the neck; the carapace ranges in color from grayish brown to brown, and the plastron is yellow or orange with black blotches along the outer edges. It is native to East Asia, ranging from central Vietnam and Laos, north through the coastal provinces of south and central China, with insular populations known from Taiwan, Hainan and the Ryukyu Islands. Although populations in the southern Ryukyus are thought to be native, populations in the northern and central Ryukyus, as well as central Japan, are believed to have been introduced as a result of imports from Taiwan.
Carnarvonia araliifolia, commonly known as the red oak, red silky oak, Caledonian oak or elephant's foot, is the sole species in the genus Carnarvonia, a member of the Proteaceae family. It is endemic to the rainforests of northeastern Queensland, Australia.
Bruno Pauletto is a physiologist, an author, a business manager, a former coach, and a former Canadian track and field athlete. He graduated from CMU and UT, and he published several books and articles on exercise physiology.
Berberidopsis beckleri is a species of climbing plant found in cool rainforests in eastern Australia. Its common name is the montane tape vine. Ferdinand von Mueller described the plant as Streptothamnus beckleri from collections at the Clarence River.
Laudakia nupta is a species of lizard from Iraq, Iran, Afghanistan, and Pakistan. It was described in 1843. There are two subspecies, Laudakia nupta nupta and Laudakia nupta fusca.
