“…Generally, genotype assignment is very accurate when the genetic structure is strong and the migration rate between populations is low. Nevertheless, genotype assignment to track true origin increases in accuracy as genetic differentiation among populations is high (Cornuet et al 1999;Jones and Wang 2012;Degen et al 2013). The highly polymorphic microsatellite loci and clear genetic structures among the populations/ species in this study are powerful and effective for future populations/species assignments (Table 5).…”

“…In an ideal case, timber species or their origins could be detected and timber logs could be traced back along the forestry supply chains (Finkeldey et al 2010;Lowe and Cross 2011). Examples of these kind of research include Intsia palembanica Miq (Lowe et al 2010), Entandrophragma cylindricum (Sprague) Sprague (Jolivet and Degen 2012), Swietenia macrophylla King (Degen et al 2013), Populus euphratica Oliv.

Cinnamomum kanehirae Hay. is endemic in Taiwan and is severely threatened due to intensive utilization and illegal logging. To combat illegal logging, suitable identification markers are needed, which are usable in a court of law, such as microsatellite marker for genotyping. In the present paper, a genetic fingerprinting database was generated based on 15 microsatellites, which are suitable to assess the timber's origin and its population genetic structure. The quality of DNA extractions from C. kanehirae timbers was assessed by comparing cpDNA trnL-trnF sequence lengths. The cumulative probability of identifying unrelated individuals in these microsatellites was 5.151 × 10 −17. The results indicate that the low genetic diversity is a consequence of illegal logging and that there is a significant genetic differentiation among C. kanehirae populations. It was possible to trace back the geographical origin of unknown C. kanehirae timbers based on a genetic reference database, i.e. all blind wood samples were assigned to their true geographical origins. Accordingly, microsatellites are a useful tool to identify the population origins of timbers and can be considered as a tool for combating illegal logging of C. kanehirae.

“…DNA fingerprinting: The use of ambient sonic spray ionization mass spectrometry as phytochemical markers [12], and DNA fingerprinting [13][14][15][16][17] has been reported for identifying timber origin, and verifying timber supply chains integrity, especially for high-valued timber. Such forestry forensics tools can be proved effective as a means against illegal logging, however the effects of population substructure and inbreeding [18] need to be taken under account.…”

Abstract. We investigate how smart Information and Communication Technologies (ICT) solutions can be used for combating illegal logging and timber trade. We put together techniques from agile requirements engineering to propose a methodology for identifying user stories and associated risks and priorities and via a collaborative, participatory, single day workshop, named inception workshop. We present our findings from the first application of the method, with the active involvement of the relevant stakeholders, i.e technical and domain experts, which concluded in seven user stories.

“…Most of mahogany wood has been obtained from natural populations in South and Central America, frequently from illegal extraction and trade. Thus, the populations of the species have been severely reduced, compromising the availability its genetic resources (WHITMORE, 2003;DEGEN et al, 2013) and its survival and perpetuation (GROGAN;LOVELESS, 2013).…”

Swietenia macrophylla yields high-quality wood; however, its vulnerability to extinction coupled with challenges for its cultivation have brought attention to its replacement for alternative species such as the Khaya anthotheca. The species has been recently introduced to South America, with potential for the production of high-quality wood. However, limited background on breeding and efficient strategies for its vegetative propagation exist. Here, we achieved significant results with the application of cleft grafting and air layering for the propagation of K. anthotheca plants grown from seeds. First, we analyzed the compatibility of scions and rootstocks for intraspecific and interspecific cleft grafting combinations of K. anthotheca and S. macrophylla. Second, air layering was performed in K. anthotheca seedlings irrigated with three nutrient solution (100%, 50% and 25% of the initial concentration of nutrients) combined with the application of indole-3-butyric acid (IBA) to evaluate adventitious rooting. From cleft grafting, we achieved an overall graft compatibility and survival of 48% after 200 days. However, the interspecific combination of S. macrophylla (scion) and K. anthotheca (rootstock) implicated in no compatibility, while the reciprocal resulted in 52% of compatibility. Through air layering, the irrigation with the nutrient solution with at least 50% of the nutrients concentration and with IBA (3.0 or 8.0 g.L-1) resulted in the best adventitious rooting. Overall, we recommend cleft grafting, except for the combination S. macrophylla (scion) and K. anthotheca (rootstock), with no compatibility. Air layering might also be useful for the propagation of K. anthotheca genotypes in breeding programs.
