Insights into the influence of priors in posterior mapping of discrete morphological characters: a case study in annonaceae
Background Posterior mapping is an increasingly popular hierarchical Bayesian based method used to infer character histories and reconstruct ancestral states at nodes of molecular phylogenies, notably of morphological ...
The enamel microstructure of Manidens condorensis: New hypotheses on the ancestral state and evolution of enamel in Ornithischia
(Polish Academy of Sciences. Institute of Paleobiology, 2020-03)
Previous studies on enamel microstructure in Ornithischia have focused on derived lineages of this clade based on species from the northern hemisphere. Here we describe the enamel microstructure of Manidens condorensis ...
Tendinous framework of anurans reveals an all-purpose morphology
(Elsevier Gmbh, 2018-02)
Tendons are directly associated with movement, amplifying power and reducing muscular work. Taking into account habitat and locomotor challenges faced by anurans, we identify the more conspicuous superficial tendons of a ...
The uropygial gland of the monk parakeet Myiopsitta monachus: Histology, morphogenesis, and evolution within Psittaciformes (Aves)
(Wiley Blackwell Publishing, Inc, 2019-11-04)
We describe the morphology, histology, and histochemical characteristics of the uropygial gland (UG) of the monk parakeet Myiopsitta monachus. The UG has a heart-shape external appearance and adenomers extensively branched ...
Embriogênese e desenvolvimento pós-seminal de Xyridaceae e Mayacaceae e anatomia floral de Xyris, com ênfase na evolução de caracteres
(Universidade Estadual Paulista (Unesp), 2018-08-30)
Xyridaceae e Mayacaceae são famílias relacionadas, incluídas na ordem Poales. Xyridaceae é grupo-irmão de Eriocaulaceae e ambas as famílias formam o clado xyrídeo. Já Mayacaceae tem posição filogenética instável, emergindo ...
Phylogenetic reconstruction of the genus Tephrocactus (Cactaceae) based on molecular, morphological, and cytogenetical data
(International Association for Plant Taxonomy, 2019-08)
Tephrocactus comprises species mainly endemic to Argentina. Molecular phylogenetic analyses of all proposed species of the genus as well as classical (chromosome number, karyotype) and molecular cytogenetical techniques ...
