Pakaraimaea Dipterocarpacea
The Ectomycorrhizal Fungal Community in a Neotropical Forest Dominated by the Endemic Dipterocarp Pakaraimaea dipterocarpacea Matthew E. Smith1*, Terry W. Henkel2, Jessie K. Uehling2, Alexander K. Fremier3, H. David Clarke4, Rytas Vilgalys5 1 Department of Plant Pathology, University of Florida, Gainesville, Florida, United States of America, 2 Department of Biological Sciences, Humboldt State University, Arcata, California, United States of America, 3 Department of Fish and Wildlife Resources, University of Idaho, Moscow, Idaho, United States of America, 4 Department of Biology, University of North Carolina Asheville, Asheville, North Carolina, United States of America, 5 Department of Biology, Duke University, Durham, North Carolina, United States of America Abstract Ectomycorrhizal (ECM) plants and fungi can be diverse and abundant in certain tropical ecosystems. For example, the primarily paleotropical ECM plant family Dipterocarpaceae is one of the most speciose and ecologically important tree families in Southeast Asia. Pakaraimaea dipterocarpacea is one of two species of dipterocarp known from the Neotropics, and is also the only known member of the monotypic Dipterocarpaceae subfamily Pakaraimoideae. This Guiana Shield endemic is only known from the sandstone highlands of Guyana and Venezuela. Despite its unique phylogenetic position and unusual geographical distribution, the ECM fungal associations of P. dipterocarpacea are understudied throughout the tree’s range. In December 2010 we sampled ECM fungi on roots of P. dipterocarpacea and the co-occurring ECM tree Dicymbe jenmanii (Fabaceae subfamily Caesalpinioideae) in the Upper Mazaruni River Basin of Guyana. Based on ITS rDNA sequencing we documented 52 ECM species from 11 independent fungal lineages. Due to the phylogenetic distance between the two host tree species, we hypothesized that P. -

INTERNATIONAL TROPICAL TIMBER ORGANIZATION ITTO PROJECT DOCUMENT TITLE: TIMBERS OF TROPICAL AFRICA PART 2: GROUP 7(2) WITHIN THE PROTA PROGRAMME SERIAL NUMBER: PD 479/07 Rev.2 (M) COMMITTEE: ECONOMIC INFORMATION AND MARKET INTELLIGENCE SUBMITTED BY: GOVERNMENT OF GHANA ORIGINAL LANGUAGE: ENGLISH BACKGROUND: As part of a total programme to improve the access to information on the 7000 useful plants of Tropical Africa and to promote their use in a sustainable manner, PROTA (Plant Resources of Tropical Africa) will make a synthesis of all existing but dispersed knowledge on the estimated 1070 ‘Timbers of Tropical Africa’ (Commodity group 7) in two Parts. This document concerns the second sub-project, on the 570 ‘Timbers of Tropical Africa’ from currently less important timber-producing taxonomic families (Commodity group 7(2)). It is preceded by a sub-project on the 500 ‘Timbers of Tropical Africa’ from the currently more important timber-producing taxonomic families (Commodity group 7(1); ITTO Project PD 264/04 Rev. 3 (M,I)). PROTA is strongly rooted in the group that successfully delivered the ITTO-funded PROSEA ‘Timber trees’ Handbook volumes.

Thèse Et Mémoire
Université de Montréal Systématique, biogéographie et diversification du genre Crudia (Leguminosae, Detarioideae) par Boris Domenech Département de Sciences Biologiques Centre sur la Biodiversité Institut de Recherche en Biologie Végétale Faculté des Arts et des Sciences Thèse présentée en vue de l’obtention du grade de Philosophiae Doctor en Sciences Biologiques Août 2018 © Boris Domenech, 2018 Résumé Le genre Crudia Schreb. présente une distribution pantropicale et une richesse spécifique élevée, inhabituelles pour un genre appartenant à la sous famille des Detarioideae (Leguminosae). Les espèces de Crudia, réparties en Amérique du Sud, en Afrique de l’Ouest et en Asie du Sud Est, ont fait l’objet de plusieurs études de taxonomie indépendantes, réalisées par plusieurs auteurs successifs. En revanche, l’évolution et l’histoire biogéographique du genre sont inconnues à ce jour. Afin de mieux comprendre l’histoire évolutive de Crudia, nous proposons une approche pluridisciplinaire visant à mettre à jour les connaissances à propos de ce genre méconnu. La première partie de cette étude a pour objectif de réaliser une révision taxonomique des espèces asiatiques du genre Crudia, les espèces africaines et américaines ayant déjà été traitées par d’autres auteurs. Nous avons pour cela utilisé des méthodes de taxonomie traditionnelle en compilant des données morphologiques sur un grand nombre de spécimens d’herbier. Sur les trente-cinq espèces initiales décrites en Asie, nous en avons retenu quatorze et avons ajouté une nouvelle espèce. Les autres espèces ont été mises en synonymie pour la plupart, exceptée l’une d’entre elle qui est à présent considérée comme douteuse. Suite à ces réassignations taxonomiques, les distributions géographiques respectives des espèces ont été réévaluées et des nouveaux statuts de conservation ont été proposés. -
