Hypnum Jutlandicum
''Hypnum jutlandicum'' is a species of moss belonging to the family Hypnaceae. It is widely distributed in Europe and the Aleutian islands but it is also found in other parts of the world. In a study of the effect of the herbicide Asulam on moss growth, ''Hypnum jutlandicum'' was shown to have intermediate sensitivity Sensitivity may refer to: Science and technology Natural sciences * Sensitivity (physiology), the ability of an organism or organ to respond to external stimuli ** Sensory processing sensitivity in humans * Sensitivity and specificity, statisti ... to Asulam exposure.

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta ('' sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. Ther ...

Hypnaceae
Hypnaceae is a large family of moss with broad worldwide occurrence in the class Bryopsida, subclass Bryidae and order Hypnales. Genera include ''Hypnum'', '' Phyllodon'', and '' Taxiphyllum''. Ecology Some of the family species occur on the floor of Canadian boreal forests; an example of this occurrence is within the black spruce/feathermoss climax forest, often having moderately dense canopy and featuring a forest floor of feathermosses including, ''Hylocomium splendens'', ''Pleurozium schreberi'' and ''Ptilium crista-castrensis''. Classification The family Hypanaceae includes the following genera: *''Acosta'' *'' Allorgea'' *'' Andoa'' *'' Austrohondaella'' *'' Breidleria'' *'' Bryocrumia'' *'' Bryosedgwickia'' *''Buckiella'' *'' Callicladium'' *'' Campylophyllum'' *'' Caribaeohypnum'' *'' Ctenidiadelphus'' *'' Ctenidium'' *'' Cupressina'' *'' Cyathothecium'' *'' Dacryophyllum'' *'' Dolichotheca'' *'' Drepanium '' *'' Ectropotheciella'' *'' Ectropotheci ...

Aleutian Islands
The Aleutian Islands ( ; ; ale, Unangam Tanangin, "land of the Aleuts"; possibly from the Chukchi ''aliat'', or "island")—also called the Aleut Islands, Aleutic Islands, or, before 1867, the Catherine Archipelago—are a chain of 14 main, larger volcanic islands and 55 smaller ones. Most of the Aleutian Islands belong to the U.S. state of Alaska, with the archipelago encompassing the Aleutians West Census Area and the Aleutians East Borough. The Commander Islands, located further to the west, belong to the Russian federal subject of Kamchatka Krai, of the Russian Far East. The islands form part of the Aleutian Arc of the Northern Pacific Ocean, and occupy a land area of 6,821 sq mi (17,666 km2) that extends westward roughly from the Alaskan Peninsula mainland, in the direction of the Kamchatka Peninsula; the archipelago acts as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing longitude 180°, at which point east and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asulam
Asulam is a herbicide invented by May & Baker Ltd , internally called M&B9057, that is used in horticulture and agriculture to kill bracken and docks. It is also used as an antiviral agent. It is currently marketed, by United Phosphorus Ltd - UPL, as "Asulox" which contains 400 g/L of asulam sodium salt. Asulam was declared not approved by the Commission Implementing Regulation (EU) No 1045/2011 of 19 October 2011 concerning the non-approval of the active substance asulam. Concerns included: lack of evidence concerning the fate of the toxic metabolite sulfanilamide Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial drug. Chemically, it is an organic compound consisting of an aniline derivatized with a sulfonamide group. Powdered sulfanilamide was used by the Allies in World War II to ... and other metabolites; the poorly characterised nature of the impurities potentially present in the technical-grade product; toxicity to birds.

Sensitivity (physiology)
In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment. The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity (excitability). Sensory receptors can receive information from outside the body, as in touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors. When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction. An internal stimulus is often the first component of a homeostatic control system. External stimuli are capable of producing systemic responses throughout the body, as in the fight-or-flight response. In order for a stimulus to be detected with high probability, its level of strength must exceed the absolute threshold; if a signal does reach threshold, the information is transmitted to the ...
