In this study, 96 nuclear 'conserved intron-scanning primers' were screened across subfamilies the Arecaceae (palms) for potential use in research focused on palm evolutionary biology. Primers were evaluated based on their ability to amplify single polymerase chain reaction products in Arecaceae, the clarity of sequencing reads, and the interspecific variability observed. Ultimately, the result...
Here, we report the results of a species level phylogenetic study of Cephaloleia beetles designed to clarify relationships and patterns of host plant taxon and tissue use among species. Our study is based on up to 2088bp of mtDNA sequence data. Maximum parsimony, maximum likelihood, and Bayesian methods of phylogenetic inference consistently recover a monophyletic Cephaloleia outside of a basal...
Four palm species, previously unknown hosts for Rhynchophorus palmarum L. (Coleoptera: Curculionidae), were killed by this invasive weevil in Balboa Park, San Diego County, California, USA. The 4 new species recorded as reproductive R. the first time are Brahea edulis, Jubaea chilensis, Phoenix reclinata, and Sabal bermudana (all Arecaceae). canariensis Chabaud (Arecaceae) is most highly attack...
A taxonomic revision of the Neotropical palm genus Leopoldinia based on morphological data and morphometric methods was carried out. One hundred and sixteen herbarium specimens were scored for seven qualitative and 24 quantitative variables. Qualitative variables were divided into six characters and one trait. Using the Phylogenetic Species Concept, the six characters were used to recognize thr...
The genus Ultratenuipalpus (Acariformes: Tenuipalpidae) was represented by 24 species prior to this study. In this paper, we describe and illustrate Ultratenuipalpus avarua sp. nov, from Cocos sp. (Arecaceae) in Avarua, Rarotonga, the Cook Islands. A key to the world species of Ultratenuipalpus is provided.
A vegetação natural no município de Ivinhema-MS é representada principalmente pela Floresta Estacional Semidecidual, substituída ao longo dos anos por pastagens, lavouras e secundária. As palmeiras (Arecaceae), consideradas elementos vitais nos ecossistemas florestais, importância ecológica econômica, com prestação diversos serviços ambientais para a fauna as populações humanas, destacam-se com...
The chromatographic fractionation of the Mauritia flexuosa L. f., Arecaceae, leaves extract, a plant known by the name of buriti palm tree, resulted in the isolation of six flavonoids: tricin-7-O-rutinoside, apigenin-6-C-arabinoside, 8-Cglucoside (isoschaftoside), kaempferol-3-O-rutinoside (nicotiflorine), quercetin-3O-rutinoside (rutin), luteolin-8-C-glucoside (orientin) and luteolin-6-C-gluco...
