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). -
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. -

Biological Control for Management of Cane Tibouchina and Other Weedy Melastome Species in Hawaii
248 Session 5 Prospects for Weed Biological Control in Pacific Islands Biological Control for Management of Cane Tibouchina and Other Weedy Melastome Species in Hawaii E. Raboin1, S. Souder2 and M. T. Johnson1 1USDA Forest Service, Pacific Southwest Research Station, Institute of Pacific Islands Forestry, Volcano, HI, USA [email protected] 2University of Hawaii at Hilo, Tropical Conservation Biology and Environmental Science, Hilo, HI, USA Abstract Syphraea uberabensis Bechyné (Coleoptera: Chrysomelidae) is a South American flea beetle whose adults and larvae feed externally on foliage and soft stems of Tibouchina spp., causing enough damage to kill small plants. Under quarantine evaluation as a potential biological control agent for cane tibouchina, Tibouchina herbacea (DC.) Cogn. (Melastomataceae), S. uberabensis has been tested on a variety of native and non-native species within the order Myrtales to identify its expected host range in Hawaii. Multi-choice behavioral tests with adult beetles and no-choice tests with adults and larvae indicated a host range restricted to several species within the tribe Melastomeae, all of which are invasive weeds in Hawaii. Preferences were found for feeding and egg laying on cane tibouchina, longleaf glorytree (Tibouchina longifolia (Vahl) Baill. ex Cogn.), false meadowbeauty (Pterolepis glomerata (Rottb.) Miq.) and Asian melastome (Melastoma septemnervium Lour.), and all four of these species were suitable hosts for the complete life cycle of S. uberabensis. Beetles appeared unlikely to impact other seriously invasive melastomes including princess flower (Tibouchina urvilleana (DC.) Cogn.), miconia (Miconia calvescens DC.) and Koster’s curse (Clidemia hirta (L.) D. Don). We consider the potential for using this biological control agent in management of multiple weedy melastomes. -

In this chapter, we attempt to describe the major types of vegetation cover in this vast region as they occurred in pre- Columbian times and outline the conditions that support them. Examining the large-scale phytogeographic regions characterized by each major cover type (see Fig. I), we provide basic information on geology, geological history, topography, and climate; describe variants of physiognomy (vegetation structure) and geography; discuss transitions; and examine some floristic patterns and affinities within and among these regions. -
Tibouchina Granulosa Glory Tree Melastomataceae
Tibouchina granulosa Glory tree Melastomataceae Forest Starr, Kim Starr, and Lloyd Loope United States Geological Survey--Biological Resources Division Haleakala Field Station, Maui, Hawai'i April, 2003 OVERVIEW Tibouchina granulosa, native to western Brazil and eastern Bolivia, is a small tree that is cultivated for its numerous attractive purple flowers (Riffle 1998). In Hawai'i, T. granulosa is rarely cultivated. On the island of Maui, T. granulosa is rarely cultivated and has been observed in a few gardens in Pukalani and Kula. T. granulosa currently is not spreading on Maui and there was no evidence found of it being invasive elsewhere in the world. However, several Tibouchina species are considered highly invasive in Hawai'i and all plants in the genus, Tibouchina, are listed as Hawai'i state noxious weeds. TAXONOMY Family: Melastomataceae (Melastoma family) (Wagner et al. 1999). Latin name: Tibouchina granulosa (Desr.) Cogn. (Wagner et al. 1999). Synonyms: Melastoma granulosum Desr. (GRIN 2003). Common names: Glory tree, purple glory tree (Dehgan 1998, Riffle 1998). Taxonomic notes: The genus, Tibouchina, is made up of about 350 species, many native to Brazil, but also ranging from Mexico and the West Indies to northern Argentina (Wagner et al. 1999). Nomenclature: The generic name is derived from a native name of the plants in Guiana (Wagner et al. 1999). Related species in Hawai'i: Several other Tibouchina species are also cultivated in Hawai'i, including T. multiflora and T. urvilleana. Tibouchina species that have naturalized in Hawai'i include T. herbacea, T. longifolia, and T. urvilleana. DESCRIPTION "Broadly 4-winged young branches, basally acute leaves, villous filaments, and uniformly purple petals." (Wagner et al. -
