Corrected 05-IV-1999. Accepted 16-IV-1999 Abstract: Seventeen natural populations in Costa Rica andPanama were used to asses geneflow and geographic patternsof genetic variation in tbis tree species. Gene flow analysis was based on the methods of rare alleles and FST (Index of genetic similarity M), using the only four polymorphic gene loci among 22 investigated (PGI-B, PGM-A, MNR-A and IDH-A). The geographic variation analysiswas based on Pearson 's correlations between four geographic and 14 genetic variables. Sorne evidence of isolation by distance and a weak gene flow among geographic regions was found. Patterns of elinal variation in relation to altitude (r = -0.62 for genetic diversity) and latitude (r = -0.77 for PGI-B3) were also observed, supporting the hypothesis of isolation by distance. No privatealleles were found at the single population level. Key words: Alnus acuminata, isozymes, gene flow, eline, geographic variation, Costa Rica, Panarna.

2005 Meeting, La Jolla, CA
Where Cures Begin. Phytochemical Society of North America Welcome to this year’s annual meeting of the Phytochemical Society of North America and to the Salk Institute for Biological Studies. The theme of this year’s meeting, integrative plant biochemistry, is meant to celebrate the past accomplishments of the organization and its scientific focus, the growing importance of phytochemistry and plant biochemistry to the public, and to set a course for the future, linking the past with the present and attracting a wider breadth of scientists and disciplines to the society as we look to 2010 and beyond. This is a critical time in plant biochemistry as the tools available to us all provide unprecedented opportunities for discovery. However, we are increasingly faced with shrinking funds available for discovery-based research. Moreover, as a society, we share a collective responsibility for mentoring future plant biochemists and phytochemists who will lead us beyond 2010. We also must increase our participation in the political process to ensure that the next generation of scientists have available the funds to make the seminal discoveries that increase our fundamental understanding of how plants have evolved to survive and prosper in challenging ecosystems. These discoveries provide the necessary foundation for translating basic research into technology that will play critical roles in the health and well being of mankind. So while you all participate in the scientific discussions throughout the meeting, jot down ideas for future meetings, thoughts on how the society can evolve and play an increasingly critical role in advocating the economic importance of plant biochemistry for future generations and how the society can lead efforts to systemize and make available the exponentially expanding amount of data we are all accumulating.

Genetic Diversity in Natural Populations of Alnus Acuminata Ssp
GENETIC DIVERSITY IN NATURAL POPULATIONS OF ALNUS ACUMINATA SSP. ARGUTA (SCHLECTENDAL) FURLOW IN COSTA RICA AND PANAMA. Olman Murillo' & Reiner Finkeldey2 ') Escuela de Ingenieria Forestal, Instituto Tecnol6gico de Costa Rica. Apartado 150-7050 Cartago, Costa Rica. Fax: 591-4182. [email protected] *'Swiss Federal Institute for Forest, Snow and Landscape Research, Ziircherstr. 11 1, CH-8903 Birmensdorf, Switzerland Received July 7, 1999; accepted March 1, 2000 ABSTRACT Alnus acurnirtnta ssp arguta (Schlect.) FURLOW(Betulaceae) is a monoecious, nitrogen fixing pioneer tree species, that occurs throughout Latin America, from central Mexico to northern Panama. 17 natural populations (54 trees/population on average) were sampled from Costa Rica and Panama. Genetic variation was assessed at putative gene loci coding for 10 isoenzyme systems. Only 4 gene loci were polymorphic. Average polymorphism (16 %), number of alleles per polymorphic locus (2.0), allelic diversity (1.29) and average heterozygosity (4 % for all loci, and 22 % for polymorphic loci) were very low in comparison to other Aln~rsspecies and other tropical trees species. Cluster analysis revealed a pattern of genetic variation associated with geography for most populations. Genetic differentiation among populations, even within the same geographical region, was larger than reported previously for other Alnus species. Repeated bottlenecks due to its early successional behavior and its association to natural catastrophies, interspaced by periods of population expansion, are the main pattern shaping the population dynamics of this species. Low gene flow, due to partial geographical isolation among and within regions, may contribute to the relative large population differentiation (1 1 % overall gene differentiation among populations was detected, with over 5 % due to among populations within same geographical region and over 5.5 % among regions).

Natural Variation in Wood Properties of Alnus Acuminata H.B.K
NATURAL VARIATION IN WOOD PROPERTIES OF ALNUS ACUMINATA H.B.K. GROWN IN COLOMBIA Roger E. Herncindez Assistant Professor Departement des Sciences du Bois et de la Forkt Universitt Laval Qdbec, Canada, G1K 7P4 and Guillermo Restrepo Former Graduate Student Dtpartement des Sciences du Bois et de la ForCt Universitk Laval Quebec, Canada, GlK 7P4 (Received February 1994) ABSTRACT Ninety-nine Andean alder (Alnus acuminata H.B.K.) trees were sampled from eleven regions in Colombia and Venezuela to determine the pattern of wood property variation between regions, between altitude within regions, between trees, and within a tree. A 5-mm-diameter increment core was extracted from each tree at breast height. The core was used to evaluate wood density and the dynamic compliance coefficient in the longitudinal direction. Based on mean regional values, wood density varied from 314 kg/m3 to 409 kg/m3; and dynamic compliance coefficient varied from 91 x MPa-I to 136 x MPa-I. Single-tree values ranged from 249 kg/m3 to 446 kg/m3 for wood density, and from 8 1 x MPa--I to 187 x MPa-I for the compliance coefficient, respectively. The analysis of variance indicated that both wood properties vary considerably between geographic locations, between trees, and within a tree. The wood density tends to increase linearly from pith to bark, although there were differences in the magnitude of increase between regions. Finally, tree characteristics (tree height and diameter at breast height) were not related to wood properties. Keywords: Wood quality, wood density, compliance coefficient, nondestructive evaluation, alder, Alnus acuminata.
