Mozambique’s natural forests are increasingly affected by climate change, deforestation, and unsustainable exploitation, threatening both biodiversity and rural livelihoods. This study examines the wood anatomical characteristics of five commercially important tree species—Spirostachys africana Sond., Afzelia quanzensis Welw., Millettia stuhlmannii Taub., Pterocarpus angolensis DC., and Colophospermum mopane (J. Kirk ex Benth.) J. Léonard—to assess their vulnerability to drought, cyclones, and floods. The aim is to enhance current knowledge regarding their wood anatomy and to clarify how these anatomical traits could help to identify species most vulnerable to climate extremes. Wood samples were collected from native forests and analyzed in laboratories in Brazil and Portugal using standardized anatomical methods according to IAWA guidelines. The results show that Afzelia quanzensis, Millettia stuhlmannii, Pterocarpus angolensis, and Colophospermum mopane have solitary vessels with vestured pits and thick-walled fibers, which improve hydraulic conductivity and drought resistance. Colophospermum mopane shows the greatest anatomical adaptation to climatic stressors. By contrast, Spirostachys africana has narrow, grouped vessels and thin walls, indicating higher susceptibility to embolism and limited resilience. Cyclone resistance is associated with higher wood density and parenchyma abundance, which enhance mechanical stability and recovery. Flood resilience, however, appears to depend more on leaf and root adaptations than on wood anatomy alone. These findings highlight the role of wood structure in climate adaptability and underline the urgency of integrating anatomical data into forest management strategies to support the conservation and sustainable use of Mozambique’s forest resources.

Neste trabalho, objetivou-se caracterizar as madeiras comercializadas como pau-de-escora na cidade de Manaus, Amazonas. Esse produto é utilizado como apoio na construção de lajes. Com exceção dos grandes prédios de apartamentos, a maioria das construções e reformas residenciais ainda utiliza esse produto, inclusive em prédios públicos. As estimativas quantitativas de dimensão e as análises anatômicas macroscópicas foram realizadas em 450 "varas" de pau-de-escora apreendidas pelo Batalhão Ambiental-AM. Houve, ainda, aplicação de questionário junto aos estabelecimentos que as vendem, para avaliar a dinâmica do comércio deste produto. O comprimento médio encontrado foi de 3,74 ± 0,08 m (IC 95%) e o diâmetro médio foi de 4,48 ± 0,03 cm (IC 95%). As sete famílias mais abundantes encontradas foram: Fabaceae, Annonaceae, Sapotaceae, Lecythidaceae, Lauraceae, Burseraceae e Chrysobalanaceae. O preço médio geral encontrado em Manaus para a compra de pau-de-escora foi R$ 2,63 e o de venda foi de R$ 3,94. Em geral, o pau-de-escora consumido em Manaus é ilegal, da produção à comercialização. Há uma padronização quanto às dimensões nas quais esse produto é comercializado, assim como o preço, nas casas comerciais que vendem irregularmente o referido material.

Objective: Describe the digitization process of the xylarium of the Federal University of Amazonas, detailing the steps, methodologies and technologies used in the creation of an accessible and functional digital repository for the collection of Amazonian woods. Theoretical Framework: The study is based on the scientific and educational importance of wood collections as biological collections that contribute to wood identification, ecological research, biodiversity conservation, and the fight against illegal trade. It highlights the need for digitization as a strategy to expand access to and management of these collections. Method: The free software Tainacan, integrated with WordPress, was used to structure the repository. The data from the 1,024 samples in the reference sub-collection were converted from manual records to standardized metadata (41 fields), with the scientific nomenclature updated and new features included, such as QR codes and search filters. Results and Discussion: Digitalization has expanded remote access and enabled advanced searches, physical-digital integration through QR codes, inclusion of geographic coordinates, scientific synonyms and anthropic uses. The platform now offers intuitive navigation, promoting research, teaching and environmental monitoring. The adoption of Tainacan has proven to be effective and replicable. Research Implications: The repository promotes the democratization of knowledge, fosters environmental education, strengthens the management of biological collections and can be replicated by other institutions. It also anticipates the use of artificial intelligence in the organization and cross-referencing of data on biodiversity. Originality/Value: The project is innovative because it adapts an open-source tool to the reality of a collection of Amazonian wood, creating an accessible, scalable and replicable digital system that combines technology with the conservation of scientific and biological heritage.

Este projeto de extensão foi desenvolvido por alunos e professores do curso de Engenharia Florestal da Universidade Federal do Amazonas e consistiu na produção de vídeos de baixo custo, a partir de celulares e câmeras digitais, entre os anos de 2015 e 2016, e a posterior veiculação em uma plataforma gratuita de vídeos. O projeto denominado Kaapeguara, que no idioma tupi significa “morador do mato”. Os vídeos produzidos englobaram temas como ciência, focados no bioma amazônico. Apesar dos recursos financeiros e técnicos escassos, os vídeos totalizam mais de 172 mil visualizações de 2015 a 2023, com impacto positivo nos discentes e nos internautas que acessaram o canal.
