This comprises 15% of the estimated 230,000 described marine species. However, this area is well known compared with other seas and the proportion of species yet to be discovered will be higher elsewhere.doi:10.1111/j.1466-8238.2010.00603.xMark J. Costello...
This study reviewed the data on the Brazilian Ephemeroptera, based on the studies published before July, 2013, estimated the number of species still to be described, and identified which regions of the country have been the subject of least research. More than half the species are known from ...

Clusters in systems as diverse as metal atoms, virus proteins, noble gases, and nucleons have properties that depend sensitively on the number of constituent particles. Certain numbers are termed ‘magic’ because they grant the system with closed shells
1 When the principal quantum number n=1, l must be equal to zero, and an electron in this state would be designated by the symbol 1s. Such a state can only have a single value of the inner quantum number m=0 but can have values of +12 or −12 for the spin quantum number s....
例5. In terms of the number of species, insects have by far the most variety of life forms. Scientists have identified and described over 1 million species of insect,compared with only about 6,000 beasts and 18,000 birds. Insects are so numerous that they contain three times as much ...
The number of male gametes is critical for reproductive success and varies between and within species. The evolutionary reduction of the number of pollen grains encompassing the male gametes is widespread in selfing plants. Here, we employ genome-wide as
In wheat, the number of spikelets per spike is fixed after the initiation of the terminal spikelet (Bonnet 1967; McMaster 1997). However, spike length and spikelet number are also known to be influenced by environmental factors, such as temperature and day length (Friend 1965; Rawson 1971; ...
ERR Names Three closely related ERR genes are known. Since the ERR genes were first names using a numbering system and then by a Greek lettering system, the nomenclature is sometimes confusing. The following table should help the reader. Species Official name: NR3B1 Human Mouse Official name: ...
of mammary cancer biology14. Thereby somatically acquired copy-number variations (CNVs) also known as copy-number alterations (CNAs)—comprising copy-number gains (CNGs) and copy-number losses (CNLs)— have been used to identify and characterise complex genomic rearrangements derived from aneuploidy ...
