1. Forensic timber identification: It's time to integrate disciplines to combat illegal logging

    Biological Conservation 191:790 (2015)

    The prosecution of illegal logging crimes is hampered by a lack of available forensic timber identification tools, both for screening of suspect material and definitive identification of illegally sourced wood. Reputable timber traders are also struggling to police their own supply cha...
  2. Rapid tree carbon stock recovery in managed Amazonian forests

    Current Biology 25(20):2738 (2015)

  3. Rapid tree carbon stock recovery in managed Amazonian forests.

    Current Biology 25(18):R787 (2015) PMID 26394096

    While around 20% of the Amazonian forest has been cleared for pastures and agriculture, one fourth of the remaining forest is dedicated to wood production. Most of these production forests have been or will be selectively harvested for commercial timber, but recent studies show that even soon af...
  4. Mid-term effects of reduced-impact logging on the regeneration of seven tree commercial species in the Eastern Amazon

    Forest Ecology and Management 274:116 (2012)

    Highlights ► Effects of reduced-impact logging (RIL) on forest structure remain over 6years. ► RIL is a treatment to increase recruitment and growth of marketable species. ► Desirable improvements of RIL on the regeneration disappear in the mid-term. ► Additional silvicultura...
  5. Sub-lethal heat shock induces plasma membrane translocation of 70-kDa heat shock protein in viable, but not in apoptotic, U-937 leukaemia cells.

    Acta Pathologica Microbiologica Scandinavica Se... 118(3):179 (2010) PMID 20132183

    Heat shock protein 70 kDa, Hsp70, is an important intracellular factor that protects cells from stress. Unusual plasma membrane expression of Hsp70, observed in some cancer cells, contributes to the cell's recognition and elimination by the immune system. Induction of apoptosis in cancer cells w...
  6. High levels of pollen dispersal detected through paternity analysis from a continuousSymphonia globuliferapopulation in the Brazilian Amazon

    Forest Ecology and Management 258(7):1260 (2009)

    In this study, six highly polymorphic microsatellite loci and a categorical paternity analysis approach were used to investigate the contemporary pollen gene flow in the neotropical tree species Symphonia globulifera. Data for this study were taken from a 500 ha experimental pl...
  7. Modelling the long-term impacts of selective logging on genetic diversity and demographic structure of four tropical tree species in the Amazon forest

    Forest Ecology and Management 254(2):335 (2008)

    In the last three decades, Amazon tropical forests have experienced high rates of deforestation, both by clearing for agriculture and by logging. In this study, we use computer simulations to examine the potential effects of forest logging on genetic diversity and demographic recovery (basa...
  8. Effects of Reduced Impact Logging on genetic diversity and spatial genetic structure of aHymenaea courbarilpopulation in the Brazilian Amazon Forest

    Forest Ecology and Management 255(3):1034 (2008)

    Levels of genetic diversity, inbreeding, and spatial genetic structure were investigated at different ontogenic stages for a population of Hymanaea courbaril, before and after Reduced Impact Logging (RIL) was applied, in a 546-ha plot in the Tapajós National Forest, in the Brazilian ...
  9. Genetic effects of selective logging and pollen gene flow in a low-density population of the dioecious tropical treeBagassa guianensisin the Brazilian Amazon

    Forest Ecology and Management 255(5):1548 (2008)

    Forest logging reduces population density and increases the distance between co-specifics and so can cause the loss of alleles, and affect the genetic diversity, spatial genetic structure (SGS), mating system, and pollen flow of the population. These factors were studied in the tropical tre...
  10. Genetic structure and mating system of Manilkara huberi (Ducke) A. Chev., a heavily logged Amazonian timber species.

    Journal of Heredity 98(7):646 (2007) PMID 17873149

    In this work, we report on the population genetic structure of the endangered tree species Manilkara huberi, an Amazonian tree species intensely exploited due to the high density and resistance of its wood. We investigated the patterns of spatial distribution, genetic structure, and mating syste...
  11. Demographic threats to the sustainability of Brazil nut exploitation.

    Science 302(5653):2112 (2003) PMID 14684819

    A comparative analysis of 23 populations of the Brazil nut tree (Bertholletia excelsa) across the Brazilian, Peruvian, and Bolivian Amazon shows that the history and intensity of Brazil nut exploitation are major determinants of population size structure. Populations subjected to persistent leve...
  12. Genetic Effects of Forest Management Practices: Global Synthesis and Perspectives

    Forest Ecology and Management 333 (1993)

    • Genetic effects of forest management practices are reviewed for boreal, temperate and tropical forests. • Response to logging is largely influenced by population...
