The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

RESUMO

Species of the genus Psilocybe have received much attention in the past due to their hallucinogenic compounds. Their diversity and distribution patterns, however, are not well understood. This study compares the distribution and abundance of most known Psilocybe species in two well-studied regions of Mexico, Veracruz in the east and Jalisco in the west, using two large taxonomic databases. Veracruz has more species relative to Jalisco, in part because this genus is well studied there. However, it seems that new species are still being found in both locations. The altitudinal distribution of species tends to be broader in Veracruz, with more species found at lower altitudes than Jalisco. This pattern could be due to fewer suitable habitats in Jalisco, or just undersampling at low altitudes. There were no differences in species distribution across different vegetations between the two regions, suggesting that Psilocybe species have niche constraints, occupying similar habitats in different regions. The comparative approach in this study is an example of how the species-rich and well-studied area of Veracruz can be used as a baseline, providing sampling guidelines in less studied regions such as Jalisco. This approach may facilitate sampling surveys, allowing for a better understanding of Psilocybe diversity and distribution.
