Mary Treat
Mary Adelia Davis Treat (7 September 1830 in Trumansburg, New York – 11 April 1923 in Pembroke, New York) was a naturalist and correspondent with Charles Darwin. Treat's contributions to both botany and entomology were extensive—six species of plants and animals were named after her, including an amaryllis, ''Zephyranthes treatae'', an oak gall wasp Bellonocnema treatae and three ant species '' Aphaenogaster mariae'', '' Aphaenogaster treatae'', and Dolichoderus mariae''. Early life Born Mary Davis to a middle-class family in Trumansburg, New York, when she was nine years old, she moved with her family to Ohio, where she attended public and private girls' schools. Davis married Dr. Joseph Burrell Treat, an abolitionist and professor, in 1863; they lived in Iowa and in 1868 they moved to Vineland, New Jersey. Career and research After her move to New Jersey, Treat began her scientific studies in earnest, and collaborated with her husband on entomology articles and res ...

Trumansburg, New York
Trumansburg is a village in Tompkins County, New York, United States. The population was 1,797 at the 2010 census. The name incorporates a misspelling of the surname of the founder, Abner Treman. The Tremans spelled their surname several different ways; "Truman," however, was not one of them. The village's application for a post office established the present spelling. The Village of Trumansburg is located within the Town of Ulysses and is northwest of Ithaca, New York. History The village was incorporated in 1872, in the former Central New York Military Tract. The village was originally named "Tremaine's Village", after an early settler, Abner Tremaine (Tremain, Treman), who was granted the land for his service in the American Revolutionary War. The village was built around a cascade on the creek that provided power for grain mills. In the 19th century Trumansburg was dominated by Col. Hermon Camp, an officer in the War of 1812 who settled in what was to become the village. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

Microscope
A microscope () is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path, by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope, electron microscope (both the transmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utricularia
''Utricularia'', commonly and collectively called the bladderworts, is a genus of carnivorous plants consisting of approximately 233 species (precise counts differ based on classification opinions; a 2001 publication lists 215 species).Salmon, Bruce (2001). ''Carnivorous Plants of New Zealand''. Ecosphere Publications. They occur in fresh water and wet soil as terrestrial or aquatic species across every continent except Antarctica. ''Utricularia'' are cultivated for their flowers, which are often compared with those of snapdragons and orchids, especially amongst carnivorous plant enthusiasts. All ''Utricularia'' are carnivorous and capture small organisms by means of bladder-like traps. Terrestrial species tend to have tiny traps that feed on minute prey such as protozoa and rotifers swimming in water-saturated soil. The traps can range in size from .Taylor, Peter. (1989).

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

John Stevens Henslow
John Stevens Henslow (6 February 1796 – 16 May 1861) was a British priest, botanist and geologist. He is best remembered as friend and mentor to his pupil Charles Darwin. Early life Henslow was born at Rochester, Kent, the son of a solicitor John Prentis Henslow, who was the son of John Henslow. Henslow was educated at St. John's College, Cambridge where he graduated as 16th wrangler in 1818, the year in which Adam Sedgwick became Woodwardian Professor of Geology. Early career Henslow graduated in 1818. He already had a passion for natural history from his childhood, which largely influenced his career, and he accompanied Sedgwick in 1819 on a tour in the Isle of Wight where he learned his first lessons in geology. He also studied chemistry under Professor James Cumming and mineralogy under Edward Daniel Clarke. In the autumn of 1819 he made valuable observations on the geology of the Isle of Man (Trans. Geol. Soc., 1821) and in 1820 and 1821 he investigated the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carnivorous Plant
Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans Protozoa (singular: protozoan or protozoon; alternative plural: protozoans) are a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris. Histo ..., typically insects and other arthropods. Carnivorous plants still generate some of their energy from photosynthesis. Carnivorous plants have adapted to grow in places where the soil is thin or poor in soil nutrient, nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875 Charles Darwin published ''Insectivorous Plants (book), Insectivorous Plants'', the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research. True carnivory is believed to have convergent evoluti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosera
''Drosera'', which is commonly known as the sundews, is one of the largest genus, genera of carnivorous plants, with at least 194 species. 2 volumes. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilage, mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.McPherson, S.R. 2008. ''Glistening Carnivores''. Redfern NaturalHistory Productions Ltd., Poole. Charles Darwin performed much of the early research into ''Drosera'', engaging in a long series of experiments with Drosera rotundifolia which were the first to confirm carnivory in plants. In an 1860 letter, Darwin wrote, “…at the present moment, I care more about ''Drosera'' than the origin of all the species in the world.” Both the botanical name (from the Ancient Greek, Greek δρ ...

Samuel Hubbard Scudder
Samuel Hubbard Scudder (April 13, 1837 – May 17, 1911) was an American entomologist and paleontologist. He was a leading figure in entomology during his lifetime and the founder of insect paleontology in America. In addition to fossil insects, he was an authority on butterflies (Lepidoptera) and grasshoppers (Orthoptera). Biography Scudder was born on April 13, 1837, in Boston, Massachusetts, the son of Charles Scudder and Sarah Lathrop (Coit) Scudder. His father was a successful merchant, and both parents had Puritan roots dating back to the founding of the Massachusetts Bay Colony in the 1620s. He was raised in a strict Calvinist Congregational household.Leach (2013) One of his younger brothers, Horace Scudder, became a noted author and editor of the ''Atlantic Monthly'',Cockerell (1911) while his niece Vida Dutton Scudder was a writer and social activist. Scudder attended Boston Latin School, and then enrolled in Williams College in 1853 at the age of 16. He studied with na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sereno Watson
Sereno Watson (December 1, 1826 in East Windsor Hill, Connecticut – March 9, 1892 in Cambridge, Massachusetts) was an American botanist. Graduating from Yale in 1847 in Biology, he drifted through various occupations until, in California, he joined the Clarence King Expedition and eventually became its expedition botanist. Appointed by Asa Gray as assistant in the Gray Herbarium of Harvard University in 1873, he later became its curator, a position he maintained until his death.
