19 Μαρ 2022 · Within Pilosocereus, five informal taxonomic groups have been recognized, one of which is P. leucocephalus group s.s., whose phylogenetic relationships remain unresolved. Therefore, our objectives are to recognize the circumscriptions of the species in P. leucocephalus group s.s. and to corroborate the monophyly and phylogenetic relationships ...
6 Οκτ 2016 · Pilosocereus is a large genus of Cactaceae with 42 species of columnar cacti distributed in the Americas. In this work we investigate the phylogenetics and evolutionary history of Pilosocereus based in plastid and nuclear DNA sequences.
1 Ιουν 2020 · The phylogenetic diversity was calculated for each cell based on a phylogram of Pilosocereus (Lavor et al., in prep) assessed with package Picante v. 1.6-2 (Kembel et al., 2010) applied in R v. 3.6.1 (R Core Team, 2019). In addition, we performed Spearman’s correlation analyses between phylogenetic diversity and species richness in each 1º x ...
The morphological characters identified to contribute to species recognition and group formation are branch diameter, areole length, the areole length-width ratio, the distance between areoles, the length of the longest radial spine, and branch and spines colors.
Pilosocereus (from Latin, "hairy cereus") is a genus of cactus native to the Neotropics. Tree cactus is a common name for Pilosocereus species. [2] The genera Caerulocereus and Pseudopilocereus are synonyms of this genus. [1] The commonly cultivated Pilosocereus pachycladus (syn. Pilosocereus azureus) is a blue cactus with hairy areoles that ...
