RESEARCH REPORT 1. Name: Sébastien ABRY (ID No.: SP05201 ) 2. Current affiliation: Ecole Normale Supérieure de Lyon 3. Research fields and specialties: Humanities Social Sciences Mathematical and Physical Sciences X Chemistry Engineering Sciences Biological Sciences Agricultural Sciences Medical, Dental and Pharmaceutical Sciences Interdisciplinary and Frontier Sciences 4. Host institution: Graduate School of Environment and Information Sciences at Yokohama National University 5. Host researcher: Pr. Hideaki YOSHITAKE 6. Description of your current research In biological systems, the oxidation of many substrates is selectively carried out by enzyme, whose hydrophobic active center contains generally at least one metal atom. The objective of my thesis consists in the creation of "bio-inspired" heterogeneous catalysts for selective oxidation reactions. Their design is based on copper enzymes such as Tyrosinase taken as bio-models. The molecular confinement and the hydrophobic nature of the metal site environment are created i) using inorganic materials with narrow pore size distribution in the nanometer scale range, ii) grafting hydrophobic functions and also chelating functions to bind copper inside the pores. MCM-41 type mesoporous silicas were selected for several reasons. This material possesses a large specific surface area (1000 m2.g-1) allowing to reach high site concentration and is handled easily in various spectroscopic experiments, including solid state NMR. The hexagonal array of pores allows a fine monitoring of the support integrity during all the synthesis steps. The narrow pore size distribution tunable in the 2-4 nm range will define a homogeneous confinement effect. Moreover, the silanol groups of the surface of the pores allow the grafting of different functions: hydrophobic or polar and/or chelating. -
Systematics and Evolution of New Caledonian Araucaria
Systematics and Evolution of New Caledonian Araucaria A thesis submitted to the University of Edinburgh for the degree of Doctor of Philosophy Mai-lan Kranitz PhD thesis The University of Edinburgh September 2005 ABSTRACT New Caledonia is a global biodiversity hotspot and contains more than 2300 endemic species including 7% of the world’s conifers. No other region in the world with such a small area possesses such a rich and distinctive conifer flora, and 13 of the world’s 19 Araucaria species are endemic to New Caledonia. This thesis has investigated the evolution and systematics of this group. A molecular phylogenetic study based on sequence data from two chloroplast regions resolved all 13 New Caledonian species as a monophyletic group, sister to the Norfolk Island Pine ( A. heterophylla ). The relationships between the New Caledonian species was not fully resolved as little sequence variability was detected, however, three main groups were defined. The species with bigger leaves occupied a basal polytomy, whereas the vast majority of species with smaller leaves were grouped together in a clade. Within this ‘small leaved’ clade, the three New Caledonian species with a coastal distribution formed another monophyletic group. The timing of the radiation of all these species was tested via a molecular clock approach using different calibration tools (fossil data, geological events, substitution rates). The precise dating of the New Caledonian radiation remains uncertain because different calibration methods give different dates. However, it seems likely to have occurred between 10 and 43 mya . What can be said is that the limited sequence divergence between these species (which in other groups would be typical of <3 million years divergence), does not tally with the fossil record and geological events. -

Distribution and Ecology of the Conifers of New Caledonia
I 1 extrait de : EGOLQGY OP THE SOUTHERN CONIFERS Edited by : Neal J. ENRIGHT and Robert S. HILL MELBOW WVERSITY PRESS - 1935 5. - I Distribution and Ecology 8 of the Conifers of - New Caledonia T. JAFFRÉ ESPITE ITS small area (19 O00 km2) New Caledonia possesses a rich and distinctive flora, totalling 3000 species of phanerogams of which 75 to 80 per cent are endemic. Among these are 43 conifers (all endemic) belonging D (1 to four families: Taxaceae (one sp.), Podocarpaceae (18 spp.), Araucariaceae 8 spp.), Cupressaceae (six spp.). \ The sole species of the family Taxaceae belongs to the endemic genus Austrotaxus. The Podocarpaceae is divided among eight genera: Podocarpus (seven ii spp.), Dacrydium (four spp.), Retrophyllum (twospp.), Falcatifolium, Dacrycarpus, Acmopyb, Prumnopitys and Parasitaxus (one sp. each), the last being endemic to New Caledonia (Page 1988). The Araucariaceae comprises two genera, Araucaria (13 spp.) and Agathis (five spp.), and the Cupressaceae the genera Libocedrus (three spp.), Callitris (two spp.), and the monotypic and endemic Neocallitropsis (de Laubenfels 1972). No other region of the world with such a small area possesses such a rich and distinctive conifer flora. Growth forms The majority of New Caledonian conifers are tall trees but there are also small trees and shrubs. The Araucariaceae, all arborescent, includes nine species exploited for their timber (Agatbis corbassonii, A. lanceolata, A. moorei, A. ovata, Araucaria columnaris, A. bernieri, A. laubenfelsii, A. luxurians, A. subulata). The Agatbis species are among the most massive forest trees; some individuals I of the tallest species, Agatbis lanceolata, have trunks more than 2.5 m in diameter and attain a height of 30-40 m. -

Phylogenetic Relationships Within Araucariaceae Based on RBCL
American Journal of Botany 85(11): 1507-1516. 1998. PHYLOGENETICRELATIONSHIPS WITHIN ARAUCARIACEAEBASED ON RBCLGENE SEQUENCES~ HlROAKI SETOGUCHI,2g5,6TAKESHI ASAKAWA OSAWA? JEAN- CHRISTOPHE PINTAUD: TANGUYJAFJXÉ: AND JEAN-MAREvEILLON4 Makino Herbarium, Faculty of Science, Tokyo Metropolitan University, Tokyo 192-03, Japan; Department of Biology, Faculty of Science, Chiba University, Chiba 246, Japan; and Department de Botanique, Centre ORSTOM de Nouméa, BP A5 Nouméa, New Caledonia Phylogenetic relationships were determined in the Araucariaceae, which are now found mainly in the Southern Hemi- sphere. This conifer family was well diversified and widely distributed in both hemispheres during the Mesozoic era. The sequence of 1322 bases of the rbcL gene of cpDNA was determined from 29 species of Araucariaceae, representing almost all the species of the family. Phylogenetic trees determined by the parsimony method indicate that Araucariaceae are well defined by rbcL sequences and also that the monophyly of Agatlzis or Araucaria is well supported by high bootstrap values. The topology of these trees revealed that Wolleiitia had derived prior to Agathis and Araucaria. The rbcL phylogeny agrees well with the present recognition of four sections within Araucaria: Araucaria, Bunya, Eutacta, and bzterinedia. Morpho- logical characteristics of the number of cotyledons, position of male cone, and cuticular micromorphologies were evaluated as being phylogenetically informative. Section Bunya was found to be derived rather than to be the oldest taxon. Infrageneric relationships of Agathis could not be well elucidated because there are few informative site changes in the rbcL gene, suggesting the more recent differentiation of the species as their fossil records indicate. The New Caledonian Araucaria and Agathis species each formed a monophyletic group with very low differentiation in rbcL sequences among them, indicating rapid adaptive radiation to new edaphic conditions, i.e., ultramafic soils, in the post-Eocene era. -

However, we lack demographic data for most species, and the data we have are often geographically aggregated. We determined to what extent existing data can be extrapolated to predict pop- ulation performance across larger sets of species and spatial areas. We used 550 matrix models, across 210 species, sourced from the COMPADRE Plant Matrix Database, to model how climate, geographic proximity and phylogeny predicted population performance. -
Some Observations on the Flora of New Caledonia* Mike Wilcox & Graeme Platt
which although clearly extremely well-known now in terms of its cultivation and conservation requirements still poses seemingly intractable problems for phylogeneticists, with a multi-authored presentation showing that its position within the family remains unclear despite sequencing several genes across the group in an effort to provide resolution: is it more closely related to Agathis, to Araucaria, or equally to the two of them? A panel discussion allowed a num- ber of other questions about Agathis and Wollemia to be considered and also served as a chance to mark the recent, premature, death of T. C. Whitmore, the first and so far the last monographer of Agathis. With that, the highly success- ful first international symposium on the Araucariaceae finished, and partici- pants began to disperse, some heading home and some remaining for the post- conference tour of New Caledonia. ACKNOWLEDGMENTS I should like to thank the Council of the International Dendrology Society very much indeed for their financial support in helping me to travel to New Zealand for the field-tour and the conference: it would have been impossible for me to attend without their assistance. I also received additional funding from the UK’s Natural Environment Research Council under grant NER/S/A/2001/06066 and a travel award from Magdalen College, Oxford: I am extremely grateful to them all. I should also like to pay tribute to the organizers, Graeme Platt, Mike Wilcox and Clive Higgie, who despite their calm unflappability throughout the field tour and the conference must clearly have worked like slaves for months and years in advance for everything to have run so extraordinarily smoothly and to whom everybody who, like me, thoroughly enjoyed the entire week, owes a tremendous debt. -

Origins and Evolution of the New Zealand Forest Flora a Molecular Phylogenetic Approach A thesis presented in partial fu lfilment of the requirements for the degree of Doctor of Philosophy in Plant Biology at Massey University, Palmerston North, New Zealand. Karen Stockier 2001 The origins and evolution of the New Zealand flora have puzzled the imagination of botanists world-wide. Competing hypotheses have sought to explain the floristic relationships between New Zealand and other Southern Hemisphere landmasses. Scientific approaches have involved geology, plant morphology, palynology and palaeobotany in investigations of the distribution patterns of these floras. Analyses presented in the current thesis use molecular data to investigate phylogenetic relationships of plant lineages native to the New Zealand forest flora. In the present thesis, molecular work included amplification and sequencing of standard DNA markers such as nuclear ribosomal DNA, ndhF and rbeL gene sequence. These data were obtained for New Zealand and overseas species of Myrsinaceae, Nothofagaceae and genus Agathis (Araucariaceae). Analyses of these data have been presented alongside results and re-analyses of genetic data for Podocarpaceae, Proteaceae, Winteraceae and genus Metrosideros (Myrtaceae). These analyses aimed to synthesise recent work and provide a framework for further molecular investigations into the origins of the New Zealand woody forest flora. Amplified fragment length polymorphism (AFLP) was used to locate polymorphic genome regions that were converted into sequence specific DNA markers.
