Summary Illegal logging and illegal timber trade is a global problem. Anatomical, genetic, chemical techniques support legislation by verifying the species geographic origin of timber. In principle, these methods can be used to identify harvest, however, availability specific tests for important unclear. We review status top 322 priority taxa. Our results show that identification, reference data exist 100% taxa using wood anatomy, 86% genetics, 41% DART TOFMS, 6% NIRS. For 24% taxa, with...
Abstract Attention to illegal logging practices and demanding policies in transnational timber trade have driven the need for species-level identification of timber. Historically wood has been identified genus level using microscopy anatomical characteristics, however, new chemometric imaging methods developed increase speed precision identification. This study approaches species a combination complementary methods: Direct Analysis Real Time–Time-of-Flight Mass Spectrometry (DART-TOFMS),...
Rationale Trade in rhinoceros horn is regulated or banned internationally recognition of its impact on wild populations worldwide. Enforcement the laws and regulations depends successfully identifying when violations occur, which complicated by presence alternative/imitation keratin (e.g., bovid keratin). In this study, we assess potential for Direct Analysis Real Time (DART) ionization paired with Time‐Of‐Flight Mass Spectrometry (DART‐TOFMS) to classify different types from four taxonomic...
The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) has listed over 100 species trees whose trade is primarily timber, existence may be endangered due to either indiscriminate or illegal logging. determination timber essential for enforcing logging quotas protections laws, but it a challenging endeavor. Here we present technique that relies mass spectra chemotypes assignment demonstrate provides high reliability.The reliability identification by...
Abstract Background To enforce timber import laws and perform species identification, the identity of botanical must be well-defined. Since Sapotaceae family is known as a taxonomically challenging family, we focus in this study on four most valuable from tropical Africa: Autranella congolensis (De Wild.) A.Chev., Baillonella toxisperma Pierre, Tieghemella africana Pierre heckelii (A.Chev.) ex Dubard. The wood anatomical characteristic fiber lumen fraction Direct Analysis Real Time—Time...
In Pterocarpus, three out of 46 tree species (P. erinaceus, P. santalinus, and tinctorius) are listed as endangered protected under Appendix II CITES, the status several Pterocarpus suggests that more will find a place on CITES in future. As unsustainable forest exploitation has increased, regulations for timber traceability have also increased with creation such laws 2005 Lacey Act United States (Lacey Act, 2005) European Union Timber Regulation (EUTR) 2013. These were implemented to ensure...
Rationale The keratin fleece of the endangered vicuña ( Vicugna vicugna ) commands a high value in international markets, and this trade has caused illegal poaching substantial decrease populations. Morphological analysis hairs does not have resolution to determine species origin camelid natural fibers. In addition, commerce also includes legal alpaca pacos guanaco L ama guanicoe wool. Methods fiber spectra n = 19), 20) were collected using X‐ray fluorescence (XRF) spectrometry, Horizontal...
Monitoring the illegal trade of wool fibres wild vicuña (Vicugna vicugna) and guanaco (Lama guanicoe) is highly desirable. The high market value fleece from these camelid species poses a threat to their populations. A previous study showed that direct analysis in real time time-of-flight mass spectrometry (DART-TOFMS) effectively identifies species. Producing high-resolution data short period makes DART-TOFMS reliable identification tool, even though can still be improved. present proposes...
Because of the rich omega-3 fatty acids content, harp seal (Pagophilus groenlandicus) oil is a popular supplement that packaged as pills in Canada and sold for medicinal purposes, although this practice banned United States. Due to US regulations, it important be able distinguish between fish oil, but taxonomic determination oils provenance has been difficult problem solve. In study, Direct Analysis Real Time time-of-flight mass spectrometry (DART TOFMS) was used analyze chemotypes blubber...
Foresters and scientists worldwide rely on the use of increment borers to collect wood cores from living trees for dendrochronology a range other applications. While there are many different types borers4-5mm diameter most frequently used. Although these standard-size devices have long history with well-established protocols, newer analyses require collection larger trees. To meet needs, researchers developed an array techniques samples but little information is available comparing...
Historically, Boswellia resin, commonly known as frankincense, has been used for a variety of applications, including medicinal purposes and in religious ceremonies. These practices continued into the modern era, which trade resin increased dramatically. The genus contains many species that are not currently protected by Convention on International Trade Endangered Species Wild Fauna Flora (CITES), but research found some these populations predicted to decrease 50% next two decades due...
A data set was constructed consisting of 3021 mass spectra randomly selected from all available families in the ForeST© (Forensic Spectra Trees) database for wood analyzed by Direct Analysis Real Time ionization coupled with time-of-flight spectrometry (DART-TOFMS). Clear and reproducible differences were observed between lignin peaks hardwood angiosperms coniferous gymnosperms, DART-TOFMS showing significantly higher relative abundances associated syringyl subunits. Application method to...
Tyrosyl-DNA Phosphodiesterase (Tdp1) is crucial for cleavage of the covalent topoisomerase-DNA complex, an intermediate in DNA repair. Tdp1 also plays a role reversing inhibition topoisomerase I by camptothecins (CPT), series potent and effective inhibitors used treatment colo-rectal carcinomas, and, ovarian small cell lung cancers. It thought that activity may reverse this resistance mechanism, restoring CPT sensitivity tumors displaying mechanism. To date, there are few published activity....
Abstract The illegal timber trade is still rampant so robust identification and tracking techniques are necessary to combat this wildlife crime. To follow enforce import laws adjoining species identification, the identity of botanical must be well defined. Since Sapotaceae family known as a taxonomically challenging family, we focus in study on four most valuable from tropical Africa: Autranella congolensis (De Wild.)
