Morphological and genetic variation within Metrosideros polymorpha (Myrtaceae) on Hawai‘i
The highly polymorphic taxon Metrosideros polymorpha (‘ohi‘a) is the most abundant endemic tree in Hawai‘i, occupying a wide but fragmented range of habitats across Federal, State, and privately managed lands. Morphological character states of 342 herbarium specimens from the island of Hawai‘i distributed the five recognised varieties in ordinal space, but intermediate phenotypes were prevalent...
متن کاملThe effects of foliar pubescence and nutrient enrichment on arthropod communities of Metrosideros polymorpha (Myrtaceae)
1. Nutrient resource availability and host-plant foliar pubescence both influence arthropod food webs, but multifactor studies are needed to understand their interdependence and relative importance. Arthropods were sampled by clipping foliage from Metrosideros polymorpha (Myrtaceae) trees of pubescent, glabrous, and intermediate leaf forms on fertilised and unfertilised plots. 2. Fertilisation ...
متن کاملContrasting Structure and Function of Pubescent and Glabrous Varieties of Hawaiian Metrosideros polymorpha (Myrtaceae) at High Elevation
Hawaiian dominant tree species Metrosideros polymorpha varieties glaberrima and polymorpha have glabrous and pubescent leaves, respectively. Sympatric populations at 2040 m elevation showed major differentiation beyond the pubescence itself. The varieties differed substantially in stomatal traits and in leaf composition, leaf water status, and instantaneous gas exchange rates, despite similarit...

S1 Figure. Representative mass spectra of putative flavanones and C-methyl flavanones detected in gland extracts of E. meulleriana S1 Fig. Multiple flavanones and C-methyl flavanones detected in gland extracts of E. meulleriana at m/z [M+H] + 271, 285 and 299 using ESI-LCMS/MS in positive mode. All compounds show the characteristic loss of 104 Da of flavanones.
متن کاملFlavonoids, Antioxidant Potential, and Acetylcholinesterase Inhibition Activity of the Extracts from the Gametophyte and Archegoniophore of Marchantia polymorpha L.
Marchantia polymorpha L. is a representative bryophyte used as a traditional Chinese medicinal herb for scald and pneumonia. The phytochemicals in M. polymorpha L. are terpenoids and flavonoids, among which especially the flavonoids show significant human health benefits. Many researches on the gametophyte of M. polymorpha L. have been reported. However, as the reproductive organ of M. polymorp...
