Biodiversity
Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distributed evenly on Earth. It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Since Abiogenesis, life began on Earth, six major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion. In this period, the majority of Multicellular organism, multicellular Phylum, phyla first appeared. The next 400 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Web Of Science
The Web of Science (WoS; previously known as Web of Knowledge) is a paid-access platform that provides (typically via the internet) access to multiple databases that provide reference and citation data from academic journals, conference proceedings, and other documents in various academic disciplines. Until 1997, it was originally produced by the Institute for Scientific Information. It is currently owned by Clarivate. Web of Science currently contains 79 million records in the core collection and 171 million records on the platform. History A citation index is built on the fact that citations in science serve as linkages between similar research items, and lead to matching or related scientific literature, such as academic journal, journal articles, conference proceedings, abstracts, etc. In addition, literature that shows the greatest impact in a particular field, or more than one discipline, can be located through a citation index. For example, a paper's influence can be d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Impact Factor
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a type of journal ranking. Journals with higher impact factor values are considered more prestigious or important within their field. The Impact Factor of a journal reflects the yearly mean number of article citations published in the last two years. While frequently used by universities and funding bodies to decide on promotion and research proposals, it has been criticised for distorting good scientific practices. Impact Factor is a scientometric index calculated by Clarivate, Clarivate's Web of Science. History The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information (ISI) in Philadelphia. Impact factors began to be calculated yearly starting from 1975 for journals listed in the ''Journal Citation Reports'' (JCR). ISI was acquired by Thomson Scientific & Healthcare in 1992, and became known as Thomson ISI. In 2018, Thomson Reuters, Thomson-Reuters ...

Scopus
Scopus is a scientific abstract and citation database, launched by the academic publisher Elsevier as a competitor to older Web of Science in 2004. The ensuing competition between the two databases has been characterized as "intense" and is considered to significantly benefit their users in terms of continuous improvement in coverage, search/analysis capabilities, but not in price. Free database The Lens completes the triad of main universal academic research databases. Journals in Scopus are reviewed for sufficient quality each year according to four numerical measures: ''h''-Index, CiteScore, SJR ( SCImago Journal Rank) and SNIP ( source normalized impact per paper). For this reason, the journals listed in Scopus are considered to meet the requirement for peer review quality established by several research grant agencies for their grant recipients and by degree-accreditation boards in a number of countries. Scopus also allows patent searches from a dedicated patent dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
