Little is known about what possible effects on wood resources might be caused by non-timber forest products (NTFPs). Here, we assessed the patterns of fuelwood consumption related to an NTFP (Caryocar coriaceum) oil extraction and how this non-domestic activity can indirectly increase the use pressure on fuelwood species in a protected area, semiarid of Brazil. We conducted semi-structured interviews, in situ inventories, phytosociological surveys, and analyses of wood quality to identify the set of woody plants used in oil production. Householders use large volumes of dry wood and a set of woody species, which are highly exploited. Additionally, many preferred species have low fuel potential and suffer much use pressure. The best fuelwood species are underused, what requires management strategies to improve their potential as a source of energy. As a result, we suggest some conservation and management actions of fuelwood resources related to the use of NTFPs.

Article Synopsis
- The basic helix-loop-helix (bHLH) transcription factor family plays a crucial role in plant growth and stress responses, but studies on this family in sea buckthorn are limited.
- The research identified 144 bHLH genes in sea buckthorn using genome-wide methods and analyzed their sequences and properties.
- The study classified these genes, revealing that 122 had high expression levels in various tissues, especially during fruit development, and validated the findings with QPCR, paving the way for further research on their functions.
Article Synopsis
- * Results indicate high genetic diversity within the native populations compared to lower diversity in plantation populations, with specific findings related to tree height and various morphological traits being significantly affected by population and environmental conditions.
- * Key factors influencing genetic diversity and morphology include temperature and soil composition, providing insights for improving plantation management and restoration efforts in degraded areas.

Prunasin and amygdalin are important factors that influence the kernel taste of apricots, however, the regulatory mechanisms underlying this are unclear. In this study, we analyzed the phenotype and transcriptome of kernels during development in (bitter kernels) and × (kernel consumption apricot, sweet kernels). Prunasin and amygdalin content was significantly higher in bitter kernels compared with that in sweet kernels.

is an edible ectomycorrhizal mushroom that forms a symbiotic association with Pinaceae trees by constructing a large extraradical mycelial area (called a shiro) in the soil. The detection of this fungal mycelium in the soil is crucial for estimating the success of outplanted mycorrhizal seedlings inoculated with under experimental conditions. Although several -specific DNA markers have been reported for efficient detection in the field, no comparative study has been conducted to assess their effectiveness.

Background: The diversity of Conservation Units in Brazil, ranging from Strict Protection areas like National Parks to Sustainable Use areas such as National Forests, supports the coexistence of human populations with extensive traditional knowledge of local natural resources. This traditional and local knowledge plays a crucial role in their subsistence and has significant potential to contribute to bioprospecting initiatives, as well as to enhance research and strategies for biological conservation. The São Sebastião de Marinaú community, situated within the Caxiuanã National Forest, offers valuable opportunities for ethnobiological studies.
