Minuca Pugnax
''Minuca pugnax'', commonly known as the Atlantic marsh fiddler crab, is a species of fiddler crab that lives on north-western shores of the Atlantic Ocean. Distribution ''Minuca pugnax'' is the most common species of fiddler crab on the east coast of the United States. Its natural range extends from Cape Cod to northern Florida. In 2014, its northern limit was extended to Hampton, New Hampshire, as a result of a range expansion possibly due to climate change. Prior to the 2000s, studies suggested that its habitat range was limited to low-marsh habitats such as creeks, bay fronts, and mosquito ditches that are regularly flooded by the tide; the number of crabs decreased substantially in high-marsh habitats. Reports also indicated that ''Minuca pugnax'' would burrow during high tide and not reemerge until the tide had receded. The habitat was therefore restricted to areas where burrows were available to occupy and could be constructed. However reports in the 2010s began noting high ...

Sidney Irving Smith
Sidney Irving Smith (February 18, 1843 in Norway, Maine – May 6, 1926 in New Haven, Connecticut) was an American zoologist. Private life Sidney Smith was the son of Elliot Smith and Lavinia Barton. His brother in law was Addison Emery Verrill. Smith married Eugenia Pocahontas Barber in New Haven, Connecticut on June 29, 1882. The couple had no children, and Eugenia died on March 14, 1916. Smith suffered from hereditary glaucoma, rendering him partially sighted from 1906, and completely blind some years before his death. He died on May 6, 1926 of throat cancer. Education and career In his youth, Sidney Irving Smith became expert on the fauna around his home town, and an expert at making collections, particularly of insects. He studied at the Sheffield Scientific School of Yale University, and received his Ph.B. in 1867. Yale University conferred upon him the honorary degree of M.A. in 1887. He stayed on at Yale, initially as an assistant, but from 1875 as the first professor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Blue
Royal blue is a deep and vivid shade of blue. It is said to have been created by clothiers in Rode, Somerset, a consortium of whom won a competition to make a dress for Queen Charlotte, consort of King George III. Brightness The ''Oxford English Dictionary'' defines "royal blue" as "a deep vivid blue", while the ''Cambridge English Dictionary'' defined it as "a strong, bright blue colour", and the ''Collins English Dictionary'' defines it as "a deep blue colour". US dictionaries give it as further towards purple, e.g. "a deep, vivid reddish or purplish blue" (''Webster's New World College Dictionary'') or "a vivid purplish blue" (''Merriam-Webster''). By the 1950s, many people began to think of royal blue as a brighter color, and it is this brighter color that was chosen as the web color "royal blue" (the web colors when they were formulated in 1987 were originally known as the X11 colors). The World Wide Web Consortium designated the keyword "royalblue" to be this much bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Alpha Taxonomy
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Maturity
Sexual maturity is the capability of an organism to reproduce. In humans it might be considered synonymous with adulthood, but here puberty is the name for the process of biological sexual maturation, while adulthood is based on cultural definitions. Most multicellular organisms are unable to sexually reproduce at birth (animals) or germination (e.g. plants): depending on the species, it may be days, weeks, or years until they have developed enough to be able to do so. Also, certain cues may trigger an organism to become sexually mature. They may be external, such as drought (certain plants), or internal, such as percentage of body fat (certain animals). (Such internal cues are not to be confused with hormones, which directly produce sexual maturity – the production/release of those hormones is triggered by such cues.) Role of reproductive organs Sexual maturity is brought about by a maturing of the reproductive organs and the production of gametes. It may also be accompanied ...

Megalopa
Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults (on the sea bed), more-so than where the larvae are planktonic, and thereby easily caught. Many crustacean larvae were not immediately recognised as larvae when they were discovered, and were described as new genera and species. The names of these genera have become generalised to cover specific larval stages across wide groups of crustaceans, such as ''zoea'' and ''nauplius''. Other terms described forms which are only found in particular groups, such as the ''glaucothoe'' of hermit crabs, or the ''phyllosoma'' of slippe ...

Plankton
Plankton are the diverse collection of organisms found in Hydrosphere, water (or atmosphere, air) that are unable to propel themselves against a Ocean current, current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air ...

Spring Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or " tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. Tide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
