Selective logging in Brazil allows for the removal of up to 90% of trees above 50 cm diameter of a given timber species, independent of a species? life history characteristics or how quickly it will recover. The genetic and demographic effects of selective logging on two Amazonian timber species (Dipteryx odorata Leguminosae, Jacaranda copaia Bignoniaceae) with contrasting ecological and reproductive characteristics were assessed in the same forest. Genetic diversity and gene flow were characterized by genotyping adults and seed sampled before and after logging, using hypervariable microsatellite markers. Overall, there were no short-term genetic impacts on the J. copaia population, with commercial application of current Brazilian forest management regulations. In contrast, for D. Odorata, selective logging showed a range of genetic impacts, with a 10% loss of alleles, and reductions in siring by pollen from trees within the 546-ha study area (23?11%) and in the number of pollen donors per progeny array (2.8?1.6), illustrating the importance of the surrounding landscape. Asynchrony in flowering between D. odorata trees led to trees with no breeding partners, which could limit the species reproduction and regeneration under current regulations. The results are summarized with other published studies from the same site and the implications for forest management discussed. The different types and levels of impacts associated with each species support the idea that ecological and genetic information by species, ecological guild or reproductive group is essential in helping to derive sustainable logging guidelines for tropical forests.

Abstract. Climate change may lead to severe losses in agriculture, including wood production. To understand the effects of climate change on physiology and molecular aspects of wood formation, we grew plants of Eucalyptus grandis and E. globulus for 35 days under three temperatures (10-12 °C, 20-22 °C, and 33-35 °C) combined with two CO2 concentrations (390 and 700 ppm). Biochemical analyses and RNAseq in stems were carried out together with leaf gas exchange measurements. We analyzed in-depth cell wall biosynthesis genes and their regulation by several transcription factors, as well as genes associated with carbon partitioning, cell wall remodeling, and hormonal regulation. E. globulus, a species adapted to low temperature, was more responsive to the treatments than E. grandis. Gene expression was greatly affected by changes in temperature than in CO2. The most relevant processes affected by the treatments were related to stress, secondary metabolism, hormonal response, and signaling. Ethylene and auxin biosynthetic genes were upregulated in both species, but more intensely in E. globulus. High CO2 stimulated lignin biosynthesis genes and increased S-containing oligomers in E. globulus. Genes related to cell wall carbohydrates and lignin were strongly induced by temperature and CO2, respectively. Photosynthesis activity and transpiration were highest under high temperature and high temperature + high CO2 in both species. Our results show that responses of woody plants may be different regarding the temperature at eCO2. MenosAbstract. Climate change may lead to severe losses in agriculture, including wood production.
