Orchids constitute one of the most spectacular radiations flowering plants. However, their origin, spread across globe, and hotspots speciation remain uncertain due to lack an up-to-date phylogeographic analysis. We present a new Orchidaceae phylogeny based on combined high-throughput Sanger sequencing data, covering all five subfamilies, 17/22 tribes, 40/49 subtribes, 285/736 genera, c. 7% (1921) 29 524 accepted species, use it infer geographic range evolution, diversity, patterns by adding...
Summary ⍰ Orchids constitute one of the most spectacular radiations flowering plants. However, their geographical origin, historical spread across globe, and hotspots speciation remain uncertain due to lack a broad phylogenomic framework. We present new Orchidaceae phylogeny based on high-throughput Sanger sequencing datasets, covering all five subfamilies, 17/22 tribes, 40/49 subtribes, 285/736 genera, ∼7% (1,921) currently 29,524 accepted species. then use it infer geographic range...
Abstract The jewel orchids (Goodyerinae), named after their often colourful leaves, have a pantropical distribution with clear Asian centre of diversity. However, the Nearctic and Neotropical America together form second diversity, one-third known species Goodyerinae. Previously, only few American samples been included in phylogenetic studies, putatively origins divergence times were poorly known. To elucidate these topics, we inferred trees, performed molecular dating reconstructed...
Abstract Pabstiella consists of c. 130 epiphytic species in the Neotropics. We present a phylogenetic analysis based on nrITS, matK and trnH-psbA sequences from 59 genus 40 Pleurothallidinae two Laeliinae one Bletiinae as an outgroup, using maximum likelihood, Bayesian inference parsimony. also performed molecular dating, biogeographical analyses ancestral morphological character reconstruction. Our results confirm monophyly with strong support. Ten clades are inferred herein proposed...
Dryadella comprises 54 neotropical species with a disjunct distribution in the Andean region and Atlantic Rainforest. This work investigated vegetative anatomy of 13 , Masdevallia infracta selected as an outgroup, to search for distinctive characteristics genus, characters differentiate Rainforest groups, traditional infrageneric classification, based mainly characters. Twenty‐seven anatomical were analysed light microscopy‐ LM scanning electron microscope‐ SEM evaluated by Cluster Principal...
Habitat selection has long been a central theme in ecology and historically considered both physiological responses ecological factors affecting species establishment. Investigating habitat patterns at different scales can provide important information on the relative roles of environmental influencing organisms’ abilities to use their surrounding habitat. This work aimed investigating which determine by Rhinella icterica tadpoles, also took opportunity investigate how scale tadpoles data...
We present the first comparative plastome study of Pleurothallidinae with analyses structural and molecular characteristics identification ten most-variable regions to be incorporated in future phylogenetic studies. sequenced complete plastomes eight species subtribe compared results these parallel their nuclear ribosomal DNA operon (26S, 18S, 5.8S plus associated spacers) partial mitochondrial genome sequences (29–38 genes introns). These have typical quadripartite structure for which gene...
In order to evaluate the monophyly of genus Orleanesia (Orchidaceae) and assess its position within Laeliinae, a phylogenetic analysis was performed using molecular (nuclear ITS plastid matK DNA sequences) morphological data. A taxonomic revision also performed, with description species fresh living plants 115 exsiccates from 31 herbaria. All analyses were highly congruent, thus sequence data all three sets combined. The resulting phylogeny corroborated Orleanesia, two strongly supported...
Abstract Dryadella (Orchidaceae, Epidendreae) is a Neotropical genus predominantly distributed in the Andean region and Atlantic rainforest (ARF). Three species occurring Brazilian ARF, edwallii , D. wuerstlei zebrina are challenge to tell apart due overlap of morphological characters that define them, so we considered these as morphotypes. To evaluate current taxonomic status identify suitable for better delimitation taxon within this group, measured analyzed 40 flower from 145 individuals...
Abstract— Even though the monophyly of Ornithocephalus clade (Oncidiinae) is currently well defined, systematic positioning Centroglossa and Dunstervillea remains obscure in due to absence previous phylogenetic studies. has a very similar habit indistinguishable from Zygostates , whereas as its main characteristic calcarate labellum, also found Centroglossa. We clarify (OC) through analysis maximum likelihood, Bayesian inference, parsimony molecular data (nrITS matK cpDNA) morphology. Our...
Prior taxonomic studies in subtribe Pleurothallidinae have suggested a close relationship between miscellaneous species featuring long-repent, segmented rhizomes, abbreviated ramicauls, few-flowered inflorescences, and flowers with partially connate sepals trilobed lip. The lack of phylogenetic information for most has prevented further conclusions or changes their taxonomy; as result, they are currently assigned to several unrelated genera: Anathallis, Madisonia, Pabstiella, Pleurothallis,...
