Identi ﬁ cation of bamboo is of great importance to its conservation and uses. However, identify bamboo manually is complicated, expensive, and time-consuming. Here, we analyze the most evident and characteristic anatomical elements of cross section images, that ’ s a particularly vital breakthrough point. Meanwhile, we present a novel approach with respect to the automatic identi ﬁ cation of bamboo on the basis of the cross-sectional images through computer vision. Two diverse transfer learning strategies were applied for the learning process, namely ﬁ ne-tuning with fully connected layers and all layers, the results indicated that ﬁ ne-tuning with all layers being trained with the dataset consisting of cross-sectional images of bamboo is an effective tool to identify and recognize intergeneric bamboo, 100% accuracy on the training dataset was achieved while 98.7% accuracy was output on the testing dataset, suggesting the proposed method is quite effective and feasible, it ’ s bene ﬁ cial to identify bamboo and protect bamboo in coutilization. More collection of bamboo species in the dataset in the near future might make Ef ﬁ cientNet more promising for identifying bamboo.","PeriodicalId":23620,"journal":{"name":"Wood and Fiber Science","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41719802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Richardson, J. Simeone, V. Deklerck","doi":"10.22382/wfs-2023-05","DOIUrl":"https://doi.org/10.22382/wfs-2023-05","url":null,"abstract":". The illegal timber trade is one of the most impactful natural wildlife crimes, affecting the live-lihood of local communities, natural resource availability, and the associated carbon storage and biodiversity. Many timber species are highly sought after and are at risk of exhaustion and subsequent extinction. Although several initiatives exist to indicate tree species risk and conservation status, there is no single resource, or prioritized list, that quali ﬁ es the most high-risk and highly traded species across the globe. Organizations end up creating their own priority species lists to meet this lack of aggregated information, requiring hours of independent research and resulting in the recreation of similar lists. To provide a one-stop-shop for similar initiatives, World Forest ID developed the Global Priority Wood Species List (GPWSL) to synthesize existing information. Currently, the GPWSL harbors 270 species most at risk for illegal logging, unsustainable deforestation, and high rates of international trade. The database contains relevant information on each species; such as natural distribution, conservation listings, and countries of import. Here, we present the list, the methods used in its development, and its potential applications for the wood industry as a whole.","PeriodicalId":23620,"journal":{"name":"Wood and Fiber Science","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46428928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brunswick, D. Shang, P. Evans","doi":"10.22382/wfs-2023-04","DOIUrl":"https://doi.org/10.22382/wfs-2023-04","url":null,"abstract":". Plantation-grown mahogany ( Swietenia macrophylla ) from Fiji has been preferred as a sustainable wood source for the crafting of electric guitars because its trade is not restricted by Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), unlike S. macrophylla sourced from native forests. Ability to differentiate between the two wood types would deter sale of illegally harvested native-grown S. macrophylla to luthiers and other artisans. The chemical composition of wood is in ﬂ uenced by cambial age and geographical factors, and there are chemical differences between S. macrophylla grown in different regions. This study tested the ability of high-resolution mass spectrometry to chemotypically differentiate plantation-grown Fijian S. macrophylla from the same wood species obtained from native forests. Multiple heartwood specimens of both wood types were extracted and chromatographically pro ﬁ led using gas and liquid chromatography tandem high-resolution quadrupole time-of-ﬂ ight mass spectrometry (GC/QToF, LC/QToF). Visual comparison of mass spectral ions, together with modern analytical data-mining techniques, were employed to screen the results. Principal component analysis scatter plots with 95% con ﬁ dence ellipses showed unambiguous separation of the two wood types by GC/LC/QToF. We conclude that screening of heartwood extractives using high-resolution mass spectrometry offers an effective way of identifying and sepa-rating plantation-grown Fijian S. macrophylla from wood grown in native forests.","PeriodicalId":23620,"journal":{"name":"Wood and Fiber Science","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49099661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
