“…As genetic structure, parentage analysis and mating system presuppose that alleles at different loci segregate independently, we undertook Mendelian inheritance analyses for each locus, based on the mother tree and her progeny as proposed by Gillet and Hattemer (1989). Considering that gametic disequilibrium creates pseudoreplication for analyses in which the loci are assumed to be independent samples of the genome, we used the FSTAT 2.9.3.2 program (Goudet, 2002) to test all loci for linkage disequilibrium, applying the Bonferroni correction for multiple comparisons (Rice, 1989).…”

Here, we explore the mating pattern and genetic structure of a tropical tree species, Cariniana estrellensis, in a small population in which progeny arrays (n = 399), all adults (n = 28) and all seedlings (n = 39) were genotyped at nine highly informative microsatellite loci. From progeny arrays we were able to identify the source tree for at least 78% of pollination events. The gene immigration rates, mainly attributable to pollen, were high, varying from 23.5 to 53%. Although gene dispersal over long distance was observed, the effective gene dispersal distances within the small population were relatively short, with mean pollination distances varying from 69.9 to 146.9 m, and seed dispersal distances occurring up to a mean of 119.6 m. Mating system analyses showed that C. estrellensis is an allogamous species (t m = 0.999), with both biparental inbreeding (t m − t s = − 0.016) and selfing rates (s = 0.001) that are not significantly different from zero. Even though the population is small, the presence of private alleles in both seedlings and progeny arrays and the elevated rates of gene immigration indicate that the C. estrellensis population is not genetically isolated. However, genetic diversity expressed by allelic richness was significantly lower in postfragmentation life stages. Although there was a loss of genetic diversity, indicating susceptibility of C. estrellensis to habitat fragmentation, no evidence of inbreeding or spatial genetic structure was observed across generations. Overall, C. estrellensis showed some resilience to negative genetic effects of habitat fragmentation, but conservation strategies are needed to preserve the remaining genetic diversity of this population.

“…No cytological observations of meiosis were made, and as the phenotypes and their frequencies in single tree progenies were compatible with disomic inheritance, B B34 B44 B24 B16 B47 B33 B23 B14 B34 B33 B44 B44 region of heteromers only tests based on the expectations of disomic segregation were made (Gillet and Hattemer, 1989). In case of autopolyploidy, the corresponding expectations were very different from those under disomic segregation, as shown for autotetraploid Prunus spinosa (Leinemann, 2000).…”

“…As no controlled crosses were carried out, the inheritance analysis method of Gillet and Hattemer (1989) was applied. This method has been used successfully for tree species, including Castanea sativa (Fineschi et al, 1989), Cupressus sempervirens L. (Papageorgiou et al, 1993), Alnus acuminata (Murillo and Hattemer, 1997), Acer campestre (Leinemann and Bendixen, 1999) and Acer pseudoplatanus ).…”

PrefaceThis book contains 24 papers selected from among those presented at an international symposium on Measuring and Monitoring Biodivcrsity in Tropical and Temperate Forests , held in Chiang Mai, Thailand, between the 27th of August and 2nd of September, 1994. The symposium was attended by over 240 scientists from more than 40 countries from around the world. In addition to four days of paper presentations, there was also a one-day field trip, and a continuous poster session, with more than 35 posters, as well as computer demonstrations of software packages for identifying and measuring biodiversity.Biodiversity is an immense subject, and as tropical and temperate forests are home to a large proportion of the earth s terrestrial biodiversity, it is obviously very difficult to cover the topic comprehensively in a single volume. The papers included in this book were selected to give as broad a coverage as possible of key topics under the general title, including Principles of Measuring and Monitoring Biodiversity (8 papers), Genetic Diversity (6 papers), Species and Ecosystem Diversity (5 papers), and Methodology (5 papers). Inevitably, forest trees are the theme of many papers, but also included are papers dealing with diversity of arthropods, microfungi, birds and butterflies, and gibbons, as well as many papers dealing with the entire range of biodiversity.We would like to thank many people who helped to make the symposium and this book possible. Among these are the sponsors of the symposium, the Royal Forest Department of Thailand, the Commission of the European Communities, the Canadian International Development Agency (including the ASEAN Forest Tree Seed Centre and SADCC Tree Seed Centre Network), the Canadian Forest Service, the U.S. Forest Service, the Center for International Forestry Research, and the International Plant Genetic Resources Institute.We would also like to acknowledge the contribution of the entire Organizing Committee in Thailand, and particularly the assistance of Ms. Rosita Go of CIFOR, for her work before, during, and after the symposium, especially in arranging financial support for developing country scientists, and preparing the manuscripts for publication. Professor Tern had been working on wild flowers and wild plants from the very beginning of his career until the end of his life. He acquired an enormous depth of experience in botany, on his own, by trekking through all the forests and regions of Thailand. His worldwide reputation meant that any visiting botanist or forest scientist were always recommended to see him when they visited Thailand.At the end of his life, he contributed actively to the debate on forest biodiversity. He was a member of the organizing committee for the IUFRO Symposium on Measuring and Monitoring Biodiversity in Tropical and Temperate Forests , held in Chiang Mai, August 27 -September 2, 1994. He presented the keynote speech at the Symposium, which is included in these Proceedings, and led participants on a field trip to examine forest biodiversity at...
