Heterodermia Rubrotricha
''Heterodermia rubrotricha'' is a foliose lichen species in the family Physciaceae. It is found in Sri Lanka. Taxonomy ''Heterodermia rubrotricha'' was formally described by Gothamie Weerakoon and André Aptroot in their 2013 study of lichen biodiversity in Sri Lanka. The species is closely related to '' Heterodermia boryi'', sharing a similar configuration, but differs distinctly by having red pigmentation on its marginal . Another related species, '' Heterodermia vulgaris'', also exhibits red pigmentation, but in that species, the pigment occurs over the entire lower surface rather than just the cilia. The species epithet ''rubrotricha'' is derived from Latin, referring to the red coloration of its cilia. Description The thallus of ''Heterodermia rubrotricha'' is foliose and can form tufts up to 10 cm in diameter. It features whitish lobes that grow linearly, ascending or becoming , reaching lengths up to 4 cm and widths of 0.9–1.6 mm. The lobes taper at t ...

Gothamie Weerakoon
Gothamie Weerakoon () is a Sri Lankan-based botanist, lichenologist and environmentalist. Early life and education Weerakoon's passion for the environment was initiated during her childhood, which she spent largely outdoors, inspired by her cousin and the natural surroundings of Diyatalawa, where she lived due to her father's military occupation. Her early education further cemented her connection to the environment, providing her with foundational knowledge about local flora and the changing seasons. This early exposure to nature deeply influenced her future academic and career choices. After completing her primary education at the Devi Balika Vidyalaya in Colombo, she attended the University of Sri Jayewardenepura, completing her PhD in 2013. Her PhD research, conducted primarily in the Knuckles Mountain Range, involved studying the activity of lichens across different habitats and establishing a comprehensive lichen checklist for the area. She emerged as the most active Sri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thin-layer Chromatography
Thin-layer chromatography (TLC) is a chromatography technique that separates components in non-volatile mixtures. It is performed on a TLC plate made up of a non-reactive solid coated with a thin layer of adsorbent material. This is called the stationary phase. The sample is deposited on the plate, which is eluted with a solvent or solvent mixture known as the mobile phase (or eluent). This solvent then moves up the plate via capillary action. As with all chromatography, some compounds are more attracted to the mobile phase, while others are more attracted to the stationary phase. Therefore, different compounds move up the TLC plate at different speeds and become separated. To visualize colourless compounds, the plate is viewed under UV light or is stained.Jork, H., Funk, W., Fischer, W., Wimmer, H. (1990): Thin-Layer Chromatography: Reagents and Detection Methods, Volume 1a, VCH, Weinheim, Testing different stationary and mobile phases is often necessary to obtain well-defined an ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Tropical
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

Tea Plantation
Tea is an aromatic beverage prepared by pouring hot or boiling water over cured or fresh leaves of ''Camellia sinensis'', an evergreen shrub native to East Asia which probably originated in the borderlands of south-western China and northern Myanmar. Tea is also made, but rarely, from the leaves of ''Camellia taliensis''. After plain water, tea is the most widely consumed drink in the world. There are many types of tea; some have a cooling, slightly bitter, and astringent flavour, while others have profiles that include sweet, nutty, floral, or grassy notes. Tea has a stimulating effect in humans, primarily due to its caffeine content. An early credible record of tea drinking dates to the third century AD, in a medical text written by Chinese physician Hua Tuo. It was popularised as a recreational drink during the Chinese Tang dynasty, and tea drinking spread to other East Asian countries. Portuguese priests and merchants introduced it to Europe during the 16th century. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camellia Sinensis
''Camellia sinensis'' is a species of evergreen shrub or small tree in the flowering plant family Theaceae. Its leaves, leaf buds, and stems can be used to produce tea. Common names include tea plant, tea shrub, and tea tree (unrelated to ''Melaleuca alternifolia'', the source of tea tree oil, or the genus ''Leptospermum'' commonly called tea tree). White tea, yellow tea, green tea, oolong, dark tea (which includes pu-erh tea) and black tea are all harvested from two of the five varieties which form the main crops now grown, ''C. sinensis'' var. ''sinensis'' and ''C. s.'' var. ''assamica'', but are Tea processing, processed differently to attain varying levels of oxidation with black tea being the most oxidized and white being the least. Kukicha (twig tea) is also harvested from ''C. sinensis'', but uses twigs and stems rather than leaves. Description ''Camellia sinensis'' is native to East Asia, the Indian Subcontinent, and Southeast Asia, but it is today cultivated all aro ...
