Merritt Lyndon Fernald
Merritt Lyndon Fernald (October 5, 1873 – September 22, 1950) was an American botanist. He was a respected scholar of the Taxonomy (biology), taxonomy and phytogeography of the vascular plant flora of temperate eastern North America. During his career, Fernald published more than 850 scientific papers and wrote and edited the seventh and eighth editions of ''Gray's Manual of Botany''. Fernald coauthored the book ''Edible Wild Plants of Eastern North America'' in 1919–1920 with Alfred Kinsey, which was published in 1943. Biography Fernald was born in Orono, Maine. His parents were Mary Lovejoy Heywood and Merritt Caldwell Fernald, a college professor at the University of Maine. Fernald attended Orono High School, during which time he decided that he wanted to become a botanist. He collected plants around Orono and published two botanical papers while still attending high school. Fernald attended Maine State College for a year, but began working as an assistant at the Gray Herba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastures
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Types of pasture Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed w ...

Indigenous Peoples Of The Americas
In the Americas, Indigenous peoples comprise the two continents' pre-Columbian inhabitants, as well as the ethnic groups that identify with them in the 15th century, as well as the ethnic groups that identify with the pre-Columbian population of the Americas as such. These populations exhibit significant diversity; some Indigenous peoples were historically hunter-gatherers, while others practiced agriculture and aquaculture. Various Indigenous societies developed complex social structures, including pre-contact monumental architecture, organized city, cities, city-states, chiefdoms, state (polity), states, monarchy, kingdoms, republics, confederation, confederacies, and empires. These societies possessed varying levels of knowledge in fields such as Pre-Columbian engineering in the Americas, engineering, Pre-Columbian architecture, architecture, mathematics, astronomy, History of writing, writing, physics, medicine, Pre-Columbian agriculture, agriculture, irrigation, geology, minin ...

Diplolepis Rosae
''Diplolepis rosae'' is a gall wasp which causes a gall known as the rose bedeguar gall, bedeguar gall wasp, Robin's pincushion, mossy rose gall, or simply moss gall.Darlington, Arnold (1975) ''The Pocket Encyclopaedia of Plant Galls in Colour.'' Pub. Blandford Press. Poole. . P. 133 - 135. The gall develops as a chemically induced distortion of an unopened leaf axillary or terminal bud, mostly on field rose (''Rosa arvensis'') or dog rose (''Rosa canina'') shrubs. The female wasp lays up to 60 eggs within each leaf bud using her ovipositor. The grubs develop within the gall, and the wasps emerge in spring; the wasp is parthenogenetic with fewer than one percent being males. A similar gall is caused by ''Diplolepis mayri'', but this is much less common. Names Being so prominent and interesting in appearance, this gall has more folklore attached to it than most. The term 'Bedeguar, Bedegar or Bedequar' comes from a French word, ''bédégar'', and is ultimately from the Persian lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galls
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls can be such highly organized structures that their cause can be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology. Anatomy Shape and size Galls develop on various plant organs, providing nutrition and shelter to inducing insects. Galls display vast variation in morphology, size, and wall composition. The size of insect galls can range significantly, from approximately two inches in diameter to less than one-sixteenth of an inch. Some galls are so small that they are merely slightly thickene ...

Diplolepis Polita
''Diplolepis polita'', known generally as the spiny leaf gall wasp, is a species of gall wasp in the family Cynipidae. It was first described by William Harris Ashmead in 1890. This species induces galls on several species of wild roses in North America, including Rosa arkansana and Rosa acicularis ''Rosa acicularis'' is a flowering plant in the Rosaceae family. It is commonly known as the prickly wild rose, prickly rose, bristly rose, wild rose or Arctic rose. It is a species of wild rose with a Holarctic distribution in northern regions o ....

Diplolepis (wasp)
''Diplolepis'' is a genus of approximately fifty species of gall-inducing wasps in the family Diplolepididae. The larvae induce galls on wild Rose, roses (''Rosa''), and rarely on domestic roses. Description Adults are small () with a strongly arched mesosoma giving them a hunched appearance. Coloration ranges from entirely orange to reddish-brown or black. Larvae are legless and cream-colored with a weakly defined head. Galls formed by a given species can usually be distinguished from those of other species by the shape, size, placement, and ornamentation (smooth or spiny) of the gall, together with the identity of the host plant. However, gall Morphology (biology), morphology can be modified by the presence of inquilines and parasitoids. Some species induce galls on leaves, while others induce galls on stems or adventitious shoots. Depending on the species of wasp, galls may be single-chambered or multi-chambered, and detachable or integral. Range ''Diplolepis'' species oc ...

Cynipidae
Gall wasps, also wikt:gallfly#Usage notes, traditionally called gallflies, are hymenopterans of the family Cynipidae in the wasp superfamily Cynipoidea. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of this generally very small creature () are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America. Features Like all Apocrita, gall wasps have a distinctive body shape, the so-called Petiole (insect anatomy), wasp waist. The first abdominal tergum (the propodeum) is conjoined with the Thorax (insect anatomy), thorax, while the second abdominal segment forms a sort of shaft, the Petiole (insect anatomy), petiole. The petiole connects with the gaster (insect anatomy), gaster, which is the functional abdomen in apocritan wasps, starting with the third abdominal segment proper. Together, the petiole and the gaster form the metasoma, while the thorax and the propodeum mak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meadows
A meadow ( ) is an open habitat or field, vegetated by grasses, herbs, and other non-woody plants. Trees or shrubs may sparsely populate meadows, as long as they maintain an open character. Meadows can occur naturally under favourable conditions but are often artificially created from cleared shrub or woodland for the production of hay, fodder or livestock. Meadow habitats as a group are characterized as semi-natural grasslands, meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife and support flora and fauna that could not thrive in other habitats. They are ecologically important since they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering if the vegetation is high enough. Intensified agricultural practices (too frequent mowing, use of mineral fertilizers, manure and insecticides) may lead to declines in the abun ...
