Ecosystem Health
Ecosystem health is a metaphor used to describe the condition of an ecosystem.Rapport, David (1998). "Defining ecosystem health." Pages 18-33 in Rapport, D.J. (ed.) (1998). ''Ecosystem Health.'' Blackwell Scientific. Ecosystem condition can vary as a result of fire, flooding, drought, extinctions, invasive species, climate change, mining, fishing, farming or logging, chemical spills, and a host of other reasons. There is no universally accepted benchmark for a healthy ecosystem, rather the apparent health status of an ecosystem can vary depending upon which health metrics are employed in judging itPalmer, Margaret A. and Catherine M. Febria (2012). "The heartbeat of ecosystems." ''Science'' 336:1393-1394. and which societal aspirations are driving the assessment. Advocates of the health metaphor argue for its simplicity as a communication tool. "Policy-makers and the public need simple, understandable concepts like health." Some critics worry that ecosystem health, a "val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ab ...

Tree Health
Trees can live for a long time but eventually die, either from natural causes or killed by man. Ill-health of trees can be diagnosed, and early treatment, pruning or felling to prevent the spread may result in timber stocks and amenity trees being saved. Tree owners and Arborists/arboriculturists need to be aware of the risk posed by hazardous trees. Construction projects sometimes avoidably damage trees. Sources of tree damage The causes of tree damage and abnormalities can conveniently be divided into either biotic (from living sources) or abiotic (from non-living sources). Biotic sources include insects (e.g. that bore into the tree), mammals (e.g. deer that rub bark off), fungi, birds, nematodes, bacteria and viroids. Abiotic sources include lightning, vehicles impacts, construction activities, drought, waterlogging, frost, winds, chemicals in the soil and air and soil nutrient deficiencies. Construction activities can involve any of a number of damage types, including grad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Pest
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Pathology
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Disease Forecasting
Plant disease forecasting is a management system used to predict the occurrence or change in severity of plant diseases. At the field scale, these systems are used by growers to make economic decisions about disease treatments for control. Often the systems ask the grower a series of questions about the susceptibility of the host crop, and incorporate current and forecast weather conditions to make a recommendation. Typically a recommendation is made about whether disease treatment is necessary or not. Usually treatment is a pesticide application. Forecasting systems are based on assumptions about the pathogen's interactions with the host and environment, the disease triangle. The objective is to accurately predict when the three factors – host, environment, and pathogen – all interact in such a fashion that disease can occur and cause economic losses. In most cases the host can be suitably defined as resistant or susceptible, and the presence of the pathogen may often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal And Plant Health Inspection Service
The Animal and Plant Health Inspection Service (APHIS) is an agency of the United States Department of Agriculture (USDA) based in Riverdale, Maryland responsible for protecting animal health, animal welfare, and plant health. APHIS is the lead agency for collaboration with other agencies to protect U.S. agriculture from invasive pests and diseases. APHIS's PPQ is the National Plant Protection Organization for the U.S., and the agency's head of veterinary services/veterinary Deputy Administrator is the Chief Veterinary Officer of the United States. History APHIS was created in 1972 by Secretary's Memorandum No. 1769. The origins of the agency predate creation of USDA, to 1854 when the Office of Entomologist, Agricultural Section, U.S. Patent Office was created. It was the first of three agencies that eventually were merged to form APHIS. In 1881, a Cattle Commission was created in the Department of the Treasury that three years later was transferred to USDA. Plant quarantine ...

Plant Protection And Quarantine
Plant Protection and Quarantine (PPQ) is one of six operational program units within the Animal and Plant Health Inspection Service (APHIS) of the United States Department of Agriculture (USDA). The PPQ works to safeguard agriculture and natural resources in the U.S. against the entry, establishment, and spread of animal and plant pests and noxious weeds, to help ensure an abundant, high-quality, and varied food supply. Plant pest program information PPQ collaborates with state departments of agriculture and other government agencies to eradicate, suppress, or contain plant pests. Such collaborations may include emergency or longer-term domestic programs to target a specific pest. Targeted pests include: * insects and mites: ** Asian longhorned beetle (ALB), ''Anoplophora glabripennis'' **cactus moth, ''Cactoblastis cactorum'' **celery leaf miner, ''Liriomyza Trifolii'' **cotton pests: *** boll weevil, ''Anthonomus grandis'' ***pink bollworm, ''Pectinophora gossypiella'' **emerald ...

Agreement On The Application Of Sanitary And Phytosanitary Measures
The Agreement on the Application of Sanitary and Phytosanitary Measures, also known as the SPS Agreement or just SPS, is an international treaty of the World Trade Organization (WTO). It was negotiated during the Uruguay Round of the General Agreement on Tariffs and Trade (GATT), and entered into force with the establishment of the WTO at the beginning of 1995. Broadly, the sanitary and phytosanitary ("SPS") measures covered by the agreement are those aimed at the protection of human, animal or plant life or health from certain risks. Under the SPS agreement, the WTO sets constraints on member-states' policies relating to food safety (bacterial contaminants, pesticides, inspection and labelling) as well as animal and plant health (phytosanitation) with respect to imported pests and diseases. There are 3 standards organizations who set standards that WTO members should base their SPS methodologies on. As provided for in Article 3, they are the Codex Alimentarius Commission (Codex), ...

Global Plant Clinic
The Global Plant Clinic (GPC) is managed by CABI in alliance with Rothamsted Research and FERA Science. The GPC provides plant health services and supports over 80 plant health clinics in Africa, Asia and Latin America. The clinic has a diagnostic service, which covers all plants and types of problems, is used by over 80 countries and helps maintain disease vigilance. The clinic also trains plant pathologists, and work with all sectors to improve regular and reliable access to technical support and advice. The clinics main aim is to create durable plant health services for those who need them most by improving access to technical support and advice. Origins Identifying plant pathogens was one of the original aims of the Imperial Bureau of Mycology which eventually became part of the Commonwealth Agricultural Bureaux (CAB) that included scientists with special skills in mycology, entomology, nematodes and later bacteria. The Commonwealth Agricultural Bureaux was later rename ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicinal Plants
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including defense and protection against insects, fungi, diseases, and herbivorous mammals. The earliest historical records of herbs are found from the Sumerian civilization, where hundreds of medicinal plants including opium are listed on clay tablets, c. 3000 BC. The Ebers Papyrus from ancient Egypt, c. 1550 BC, describes over 850 plant medicines. The Greek physician Dioscorides, who worked in the Roman army, documented over 1000 recipes for medicines using over 600 medicinal plants in ''De materia medica'', c. 60 AD; this formed the basis of pharmacopoeias for some 1500 years. Drug research sometimes makes use of ethnobotany to search for pharmacologically active substances, and this approach has yielded hundreds of useful compounds. These include the common drugs aspi ...
