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). -

Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

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. -
Epidemiology of the Invasion by Miconia Calvescens And
J.-Y. Meyer 4 EPIDEMIOLOGY OF THE INVASION BY MICONIA CALVESCENS AND REASONS FOR A SPECTACULAR SUCCESS ÉPIDÉMIOLOGIE DE L’INVASION PAR MICONIA CALVESCENS ET RAISONS D’UN SUCCÈS SPECTACULAIRE JEAN-YVES MEYER1, 2 1 Délégation à la Recherche, B.P. 20981 Papeete, Tahiti, POLYNÉSIE FRANÇAISE. 2 Cooperative National Park Resource Studies Unit, Botany Department, University of Hawai’i at Manoa, Honolulu, HAWAI’I (USA). Miconia calvescens is a small tree native to rainforests of tropical America where it is uncommon. First described around 1850, it was introduced to European tropical greenhouses then distributed to tropical botanical gardens all over the world because of its horticultural success. M.c. was introduced as an ornamental plant in the Society Islands and the Hawaiian Islands and in 25-35 years became a dominant invasive plant in both archipelagoes. Small populations were recently discovered in the Marquesas Islands (Nuku Hiva and Fatu Iva) in 1997. M.c. is also naturalized in private gardens of New Caledonia and Grenada (West Indies), in tropical forests of Sri Lanka, and in the Queensland region in Australia. The survey of the epidemiology of invasion in Tahiti shows that M.c.’s extension was slow but continuous since its introduction in 1937. Hurricanes of 1982-83 played more a role of “revealer” rather than of “detonator” of the invasion. The lag phase observed between the introduction date and the observation of dense populations may be explained by the generation time of M.c.. Several hypothesis may explain the spectacular success of M.c.: (1) the characteristics of the invaded area; (2) the plant’s bio-ecological characteristics; (3) the “facilitation phenomenon“ and the “opportunities“. -

Albatross Or Mōlī (Phoebastria Immutabilis) Black-Footed Albatross Or Ka’Upu (Phoebastria Nigripes) Short-Tailed Albatross (Phoebastria Albatrus)
Hawaiian Bird Conservation Action Plan Focal Species: Laysan Albatross or Mōlī (Phoebastria immutabilis) Black-footed Albatross or Ka’upu (Phoebastria nigripes) Short-tailed Albatross (Phoebastria albatrus) Synopsis: These three North Pacific albatrosses are demographically similar, share vast oceanic ranges, and face similar threats. Laysan and Black-footed Albatrosses nest primarily in the Northwestern Hawaiian Islands, while the Short-tailed Albatross nests mainly on islands near Japan but forages extensively in U.S. waters. The Short-tailed Albatross was once thought to be extinct but its population has been growing steadily since it was rediscovered in 1951 and now numbers over 3,000 birds. The Laysan is the most numerous albatross species in the world with a population over 1.5 million, but its trend has been hard to determine because of fluctuations in number of breeding pairs. The Black-footed Albatross is one-tenth as numerous as the Laysan and its trend also has been difficult to determine. Fisheries bycatch caused unsustainable mortality of adults in all three species but has been greatly reduced in the past 10-20 years. Climate change and sea level rise are perhaps the greatest long-term threat to Laysan and Black-footed Albatrosses because their largest colonies are on low-lying atolls. Protecting and creating colonies on higher islands and managing non-native predators and human conflicts may become keys to their survival.
