Status, Ecology, and Management of the Invasive Plant, Miconia Calvescens DC (Melastomataceae) in the Hawaiian Islands1
Records of the Hawaii Biological Survey for 1996. Bishop 23 Museum Occasional Papers 48: 23-36. (1997) Status, Ecology, and Management of the Invasive Plant, Miconia calvescens DC (Melastomataceae) in the Hawaiian Islands1 A.C. MEDEIROS2, L.L. LOOPE3 (United States Geological Survey, Biological Resources Division, Haleakala National Park Field Station, P.O. Box 369, Makawao, HI 96768, USA), P. CONANT (Hawaii Department of Agriculture, 1428 South King St., P.O. Box 22159, Honolulu, HI 96823, USA), & S. MCELVANEY (Hawaii Natural Heritage Program/The Nature Conservancy of Hawaii, 1116 Smith St., Suite 201, Honolulu, HI 96817, USA) Abstract Miconia calvescens (Melastomataceae), native to montane forests of the neotropics, has now invaded wet forests of both the Society and Hawaiian Islands. This tree, which grows up to 15 m tall, is potentially the most invasive and damaging weed of rainforests of Pacific islands. In moist conditions, it grows rapidly, tolerates shade, and produces abundant seed that is effectively dispersed by birds and accumulates in a large, persistent soil seed-bank. Introduced to the Hawaiian Islands in 1961, M. calvescens appears to threaten much of the biological diversity in native forests receiving 1800–2000 mm or more annual precipitation. Currently, M. calvescens is found on 4 Hawaiian islands— Hawaii, Maui, Oahu, and Kauai. Widespread awareness of this invader began in the early 1990s. Although biological control is being pursued, conventional control techniques (mechanical and chemical) to contain and eradicate it locally are underway. Introduction The effects of biological invasions are increasingly being recognized for their role in degradation of biological diversity worldwide (Usher et al., 1988; D’Antonio & Vitousek, 1992). -

HEAR HNIS Report on Miconia Calvescens
Saturday, March 29, 1997 HNIS Report for Miconia calvescens Page 1 A product of the Hawaiian Ecosystems at Risk Project Miconia calvescens DC. Miconia calvescens, in the melastome family (Melastomataceae), is a tree 4-15 m tall with large (to 80 cm in length), strongly trinerved leaves, dark-green above and purple below. Federal Noxious Weed? N Hawaii State Noxious Weed? Y Federal Seed Act? N Hawaii State Seed Act? N [illustration source: unknown] Native to where : The native range of Miconia calvescens extends from 20 degrees N in Mexico, Guatemala, and Belize to 20 degrees S in Brazil and Argentina (Meyer 1994). The upper elevational limit of the species in its native range is 1830 m in Ecuador (Wurdack 1980). Meyer (1994) determined that the form with very large leaves with purple leaf undersides occurs only in Mexico, Guatemala, Belize, and Costa Rica; specimens examined by Meyer were collected at elevations between 45 m and 1400 m. Native climate : The climate in which Miconia calvescens occurs is tropical montane. Based on its ecology in Tahiti and its occurrence to 1830 m in Ecuador, it appears to pose a threat to all habitats below the upper forest line which receive 1800-2000 mm (75-80 inches) or more of annual precipitation. Biology and ecology : Phenology: Flowering and fruiting of mature trees in Miconia calvescens populations in Hawaii appear to be somewhat synchronized and may be triggered by weather events (drought and/or rain). A single tree can flower/fruit 2-3 times in a year. A single flowering/fruiting event is prolonged, and all stages and mature and immature fruits are often seen on a single tree. -
Phylogeny and Classification of the Melastomataceae and Memecylaceae
Nord. J. Bot. - Section of tropical taxonomy Phylogeny and classification of the Melastomataceae and Memecy laceae Susanne S. Renner Renner, S. S. 1993. Phylogeny and classification of the Melastomataceae and Memecy- laceae. - Nord. J. Bot. 13: 519-540. Copenhagen. ISSN 0107-055X. A systematic analysis of the Melastomataceae, a pantropical family of about 4200- 4500 species in c. 166 genera, and their traditional allies, the Memecylaceae, with c. 430 species in six genera, suggests a phylogeny in which there are two major lineages in the Melastomataceae and a clearly distinct Memecylaceae. Melastomataceae have close affinities with Crypteroniaceae and Lythraceae, while Memecylaceae seem closer to Myrtaceae, all of which were considered as possible outgroups, but sister group relationships in this plexus could not be resolved. Based on an analysis of all morph- ological and anatomical characters useful for higher level grouping in the Melastoma- taceae and Memecylaceae a cladistic analysis of the evolutionary relationships of the tribes of the Melastomataceae was performed, employing part of the ingroup as outgroup. Using 7 of the 21 characters scored for all genera, the maximum parsimony program PAUP in an exhaustive search found four 8-step trees with a consistency index of 0.86. Because of the limited number of characters used and the uncertain monophyly of some of the tribes, however, all presented phylogenetic hypotheses are weak. A synapomorphy of the Memecylaceae is the presence of a dorsal terpenoid-producing connective gland, a synapomorphy of the Melastomataceae is the perfectly acrodro- mous leaf venation. Within the Melastomataceae, a basal monophyletic group consists of the Kibessioideae (Prernandra) characterized by fiber tracheids, radially and axially included phloem, and median-parietal placentation (placentas along the mid-veins of the locule walls). -
Pollination Ecology Summary
Pollination Ecology Summary Prof. em. Klaus Ammann, Neuchâtel [email protected] June 2013 Ohne den Pollenübertragungs-Service blütenbesuchender Tiere könnten sich viele Blütenpanzen nicht geschlechtlich fortpanzen. Die komplexen und faszinierenden Bestäubungsvorgänge bei Blütenpanzen sind Ausdruck von Jahrmillionen von Selektionsvorgängen, verbunden mit Selbstorganisation der Lebewesen; eine Sicht, die auch Darwin schon unterstützte. Bei vielen zwischenartlichen Beziehungen haben sich zwei oder auch mehrere Arten in ihrer Entwicklung gegenseitig beeinusst. Man spricht hier von sogenannter Coevolution. Deutlich ist die Coevolution auch bei verschiedenen Bestäubungssystemen und -mechanismen, die von symbiontischer bis parasitischer Natur sein können.

Demographic History and the Low Genetic Diversity in Dipteryx Alata (Fabaceae) from Brazilian Neotropical Savannas
Heredity (2013) 111, 97–105 & 2013 Macmillan Publishers Limited All rights reserved 0018-067X/13 www.nature.com/hdy ORIGINAL ARTICLE Demographic history and the low genetic diversity in Dipteryx alata (Fabaceae) from Brazilian Neotropical savannas RG Collevatti1, MPC Telles1, JC Nabout2, LJ Chaves3 and TN Soares1 Genetic effects of habitat fragmentation may be undetectable because they are generally a recent event in evolutionary time or because of confounding effects such as historical bottlenecks and historical changes in species’ distribution. To assess the effects of demographic history on the genetic diversity and population structure in the Neotropical tree Dipteryx alata (Fabaceae), we used coalescence analyses coupled with ecological niche modeling to hindcast its distribution over the last 21 000 years. Twenty-five populations (644 individuals) were sampled and all individuals were genotyped using eight microsatellite loci. All populations presented low allelic richness and genetic diversity. The estimated effective population size was small in all populations and gene flow was negligible among most. We also found a significant signal of demographic reduction in most cases. Genetic differentiation among populations was significantly correlated with geographical distance. Allelic richness showed a spatial cline pattern in relation to the species’ paleodistribution 21 kyr BP (thousand years before present), as expected under a range expansion model. Our results show strong evidences that genetic diversity in D. alata is the outcome of the historical changes in species distribution during the late Pleistocene. Because of this historically low effective population size and the low genetic diversity, recent fragmentation of the Cerrado biome may increase population differentiation, causing population decline and compromising long-term persistence. -

PhytoKeys 136: 1–21. https://doi.org/10.3897/ phytokeys.136.38558 Abstract The systematics of Tryssophyton, herbs endemic to the Pakaraima Mountains of western Guyana, is re- viewed and Tryssophyton quadrifolius K.Wurdack & Michelang., sp. nov. from the summit of Kamakusa Mountain is described as the second species in the genus. The new species is distinguished from its closest relative, Tryssophyton merumense, by striking vegetative differences, including number of leaves per stem and leaf architecture. A phylogenetic analysis of sequence data from three plastid loci and Melastomata- ceae-wide taxon sampling is presented. The two species of Tryssophyton are recovered as monophyletic and associated with mostly Old World tribe Sonerileae. Fruit, seed and leaf morphology are described for the first time, biogeography is discussed and both species are illustrated.
