Progressive island colonization and ancient origin of Hawaiian Metrosideros (Myrtaceae).
Knowledge of the evolutionary history of plants that are ecologically dominant in modern ecosystems is critical to understanding the historical development of those ecosystems. Metrosideros is a plant genus found in many ecological and altitudinal zones throughout the Pacific. In the Hawaiian Islands, Metrosideros polymorpha is an ecologically dominant species and is also highly polymorphic in ...
متن کاملMorphological 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 Floral Biology, Breeding System and Pollination Efficiency of Schima superba Gardn. et Champ. (Theaceae)
Schima superba Gardn. et Champ. is a perennial, evergreen tree valued for its eco-protection and commercial values in China. In this study, we investigate the breeding system, reproductive ecology and pollination biology of S. superba in a seed orchard. The flowers are hermaphrodite and protogynous. The viability of the pollen is inactivated rapidly, and the stigma maintains a high receptivity ...
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 کاملSuccessional processes induced by fires on the northern offshore islands of New Zealand
Major trends in forest successions following fires are identified for northern offshore islands of New Zealand. Data are from the author’s observations over several decades, and published descriptions. Islands studied extend from the Cavalli group in the north to the Aldermen group in the south. Their original vegetation was largely destroyed by human-induced fires. Successions that followed we...
