Hemiepiphyte
A hemiepiphyte is a plant that spends part of its life cycle as an epiphyte. The seeds of primary hemiepiphytes germinate in the canopy and initially live epiphytically. They send roots downward, and these roots eventually make contact with the ground. Secondary hemiepiphytes are root-climbers that begin as rooted vines growing upward from the forest floor, but later break their connection to the ground. When this happens, they may send down long roots to the ground.Mayo et al. "Araceae" in Kubitzki (1998b ''The families and genera of vascular plants''): "The root climbers and hemiepiphytes normally grow in humid forests, often very high in the canopy. When losing connection with the forest floor, they may send down long roots to the ground; such plants may be referred to as secondary hemiepiphytes. Hemiepiphytes and root climbers cling tightly to the bark of the host with negatively phototropic roots. Skototropism, an orientation movement towards a well-defined dark area, ha ...

Elaeocarpus Holopetalus Hemiepiphyte Devils Creek Tantawangalo
''Elaeocarpus'' is a genus of nearly five hundred species of flowering plants in the family Elaeocarpaceae native to the Western Indian Ocean, Tropical and Subtropical Asia, and the Pacific. Plants in the genus ''Elaeocarpus'' are trees or shrubs with simple leaves, flowers with four or five petals usually, and usually blue fruit. Description Plants in the genus ''Elaeocarpus'' are mostly evergreen trees or shrubs, a few are epiphytes or lianes, and some are briefly deciduous. The leaves are arranged alternately, simple (strictly compound with only one leaflet) with a swelling where the petiole meets the lamina, often have toothed edges, usually have prominent veins and often turn red before falling. The flowers are usually arranged in a raceme, usually bisexual, have four or five sepals and petals and many stamens. The petals usually have finely-divided, linear lobes. The fruit is a oval to spherical drupe that is usually blue, sometimes black, with a sculptured endoca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucryphia Moorei & Dicksonia Monga
''Eucryphia'' is a small genus of trees and large shrubs native to the south temperate regions of South America and coastal eastern Australia, mainly Tasmania. Sometimes placed in a family of their own, the Eucryphiaceae, more recent classifications place them in the Cunoniaceae. There are seven species, two in South America and five in Australia, and several named hybrids. Description They are mostly evergreen though one species (''E. glutinosa'') is usually deciduous. The leaves are opposite, and either simple or pinnate with 3-13 leaflets. The flowers are produced in late summer or autumn, are showy and sweetly scented, 3–6 cm diameter, with four creamy-white petals, and numerous stamens and styles. The fruit is a woody capsule 1-1.5 cm long containing several seeds, and maturing in 12–15 months. Etymology The generic name ''Eucryphia'' is composed of two parts, namely ''eu-'' and ''-cryphia''. The Greek ευ-κρυφαιος means well-covered and refers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphyte
An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strangler Fig
Strangler fig is the common name for a number of tropical and subtropical plant species in the genus ''Ficus'', including those that are commonly known as banyans. Some of the more well-known species are: * ''Ficus altissima'' * ''Ficus aurea'', also known as the Florida strangler fig * ''Ficus benghalensis'' * ''Ficus benjamina'' * '' Ficus burtt-davyi'' * ''Ficus citrifolia'' * '' Ficus craterostoma'' * ''Ficus tinctoria'' * ''Ficus macrophylla'' * ''Ficus obliqua'' * ''Ficus virens'' *''Ficus watkinsiana'' *''Ficus henneana'' These all share a common "strangling" growth habit that is found in many tropical forest species, particularly of the genus ''Ficus''. This growth habit is an adaptation for growing in dark forests where the competition for light is intense. Strangler figs suck up the nutrients from its victims, causing them to die eventually. These plants are hemiepiphytes, spending the first part of their life without rooting into the ground. Their seeds, often bird- dis ...

Girdling
Girdling, also called ring-barking, is the complete removal of the Bark (botany), bark (consisting of cork cambium or "phellogen", phloem, cambium and sometimes going into the xylem) from around the entire circumference of either a branch or trunk (botany), trunk of a woody plant. Girdling results in the death of the area above the girdle over time. A branch completely girdled will fail and when the main trunk of a tree is girdled, the entire tree will die, if it cannot regrow from above to bridge the wound. Human practices of girdling include forestry, horticulture, and vandalism. Foresters use the practice of girdling to thin forests. Animals such as rodents will girdle trees by feeding on outer bark, often during winter under snow. Girdling can also be caused by herbivorous mammals feeding on plant bark and by birds and insects, both of which can effectively girdle a tree by boring rows of adjacent holes. Orchardists use girdling as a cultural technique to yield larger fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecology Terminology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource management (ag ...

Plant Morphology
Phytomorphology is the study of the morphology (biology), physical form and external structure of plants.Raven, P. H., R. F. Evert, & S. E. Eichhorn. ''Biology of Plants'', 7th ed., page 9. (New York: W. H. Freeman, 2005). . This is usually considered distinct from plant anatomy, which is the study of the internal Anatomy, structure of plants, especially at the microscopic level. Plant morphology is useful in the visual identification of plants. Recent studies in molecular biology started to investigate the molecular processes involved in determining the conservation and diversification of plant morphologies. In these studies transcriptome conservation patterns were found to mark crucial ontogenetic transitions during the plant life cycle which may result in evolutionary constraints limiting diversification. Scope Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarit ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...
