Frederick Traugott Pursh
Frederick Traugott Pursh (or Friedrich Traugott Pursch) (February 4, 1774 – July 11, 1820) was a German people, German–United States, American botanist. Born in Großenhain, in the Electorate of Saxony, under the name Friedrich Traugott Pursh, he was educated at Dresden Botanical Gardens, and emigrated to the United States in 1799. From 1802 to 1805, he worked in Philadelphia as the botanical manager of the extensive gardens of William Hamilton, Esq., "The Woodlands (Philadelphia), The Woodlands." By 1805, he was working for Benjamin Smith Barton on a new Flora (publication), flora of North America, under whom he studied the plants collected on the Lewis and Clark Expedition. His work with Barton allowed him to travel farther afield. In 1805, he traveled south from Maryland to the Carolinas and, in 1806, he traveled north from the mountains of Pennsylvania to New Hampshire. He made both trips principally on foot, with only his dog and a gun, covering over three thousand miles e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

John Goldie (botanist)
John Goldie (21 March 1793 – 23 July 1886) was a Scottish-born botanist, author, and miller. He is credited with recording the existence of fourteen plant species previously unknown to science including ''Dryopteris goldieana'', '' Stellaria longipes'' and '' Drosera linearis''. Early life and education Goldie was born in Kirkoswald in 1793, the son of William Goudie and Janet McClure. As a teenager, Goldie had apprenticed as a gardener and was later employed at the Glasgow Botanic Garden where he accumulated most of his knowledge of botany. Having studied language at the University of Glasgow, Goldie was fluent in Greek, French, and Hebrew, although he never registered for a degree due to financial problems.P. M. Eckel. John Goldie in North America, Parts 1 and 2. Clintonia Vol. 4, Issue 5, Pages 1-5. September 6, 1989. While in Glasgow, he made the acquaintance of James Smith, a well-known local botanist and florist, and began spending time at his home near Minish ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Biological Dispersal
Biological dispersal refers to both the movement of individuals (animals, plants, fungi, bacteria, etc.) from their birth site to their breeding site ('natal dispersal') and the movement from one breeding site to another ('breeding dispersal'). Dispersal is also used to describe the movement of propagules such as seeds and spores. Technically, dispersal is defined as any movement that has the potential to lead to gene flow. The act of dispersal involves three phases: departure, transfer, and settlement. There are different fitness costs and benefits associated with each of these phases. Through simply moving from one habitat Landscape ecology#Patch and mosaic, patch to another, the dispersal of an individual has consequences not only for individual fitness (biology), fitness, but also for population dynamics, population genetics, and species distribution. Understanding dispersal and the consequences, both for evolutionary strategies at a species level and for processes at an e ...
