“…Second, SDM model was developed to quantify the relationship between breadfruit presence and the selected bioclimatic variables including its inverse variables, as reported in this study was climate change ( Yi et al., 2016 ). The uses of SDM in this study to assess the impacts of climate changes on the potential distribution of vegetation were in agreement with the previous study ( Ali et al., 2023 ; Daï et al., 2023 ).…”

Artocarpus altilis, commonly known as breadfruit, is a potential crop adapted to a wide variety of climates and widely spread, including in Indonesia. However, information on how this species can adapt to climate change, in particular in Central Java, is still limited. In Indonesia, Central Java is the center for cultivation areas for many crop species to support the 145 million people living on Java Island. One of the potential crops being developed in Central Java is breadfruit. To assess the suitable cultivation areas for breadfruit, species distribution modeling (SDM) was used to predict the current and future (2050–2070) distribution of breadfruit. Two climate change scenarios, including optimistic RCP2.6 and pessimistic RCP8.5 models, were considered to represent future climate change impacts. Based on the results for both optimistic and pessimistic scenarios, the breadfruit’s suitable cultivation areas will expand eastward. Implementing a mitigation climate change scenario and limiting the temperature increase to only 1°C under RCP2.6 will provide 270.967 km2 more of suitable cultivation areas for breadfruit in 2050 and 133.296 km2 in 2070. To conclude, this study provides important information on the status and potential cultivation areas for breadfruit, mainly in the Southeast Asia region. The identification of suitable areas will guide land conservation for breadfruit to support food security in this region.

“…Les écosystèmes naturels et les espèces sauvages d'animaux, de plantes ou de champignons sont généralement utilisés pour la satisfaction des besoins fondamentaux des communautés locales (Daï et al, 2023). Les ressources naturelles sont donc d'une importance capitale pour améliorer la sécurité alimentaire et les conditions de vie des communautés locales (Fisher et al, 2013).…”

Pseudrocedrela Kotschyi est une espèce très important pour les communautés locales en raison de ses multiples utilisations, notamment alimentaires, médicinales, industrielles et technologiques. Elle est fortement touchée par la dégradation de son habitat aussi bien en milieu naturel ainsi que dans les parcs agro-forestiers. Face à cette dégradation il est impérieux de trouver des mécanismes durables de conservation de cette ressource. La présente étude visait à évaluer les paramètres de diversité des habitats de Pseudrocedrela kostchyi en fonction de la zone climatique et de la pression anthropique au Benin. Pour y arriver des données dendrométriques ont été collectées dans chaque zone climatique suivant deux niveaux de protection. La diversité floristique de l’habitat a été déterminée grâce à la richesse spécifique et les indices de diversité (Shannon et Equitabilité de Pielou). Par ailleurs, l’Indice de Valeur d’Importance (IVI) a été calculé pour caractériser la composition spécifique (dbh ≥ 10 cm) et évaluer la disponibilité locale des espèces ligneuses dans les habitats. Les résultats ont montré que les habitats de la zone soudano-guinéenne étaient plus riches en espèces et plus diversifiés, suivis de la zone soudanienne et de la zone guinéo-congolaise. La plupart des valeurs des indices de diversité étaient les plus élevées dans les habitats protégés sauf en zone guinéo-congolaise où la tendance contraire est observée. En ce qui concerne la composition floristique, les espèces les plus importantes trouvées dans chaque habitat étaient presque les mêmes quel que soit le statut de l’habitat. Ces résultats obtenus sont utiles pour une meilleure stratégie de conservation durable des populations de l’espèce. Pseudrocedrela Kotschyi is a very important species for local communities because of its multiple uses, including food, medicine, industry and technology. It has been severely affected by the degradation of its habitat, both in the wild and in agroforestry parks. Faced with this degradation, it is imperative to find sustainable mechanisms for conserving this resource. The aim of the present study was to assess the diversity parameters of Pseudrocedrela kostchyi habitats as a function of climatic zone and anthropogenic pressure in Benin. To achieve this, dendrometric data were collected in each climatic zone according to two levels of protection. The floristic diversity of the habitat was determined using species richness and diversity indices (Shannon and Pielou Equitability). In addition, the Importance Value Index (IVI) was calculated to characterize the specific composition (dbh ≥ 10 cm) and assess the local availability of woody species in the discriminated habitats. The results showed that habitats in the Sudano-Guinean zone are richer in species and more diverse, followed by the Sudanian and Guineo-Congolian zones. Most diversity index values are highest in protected habitats, except in the Guinean-Congolian zone, where the opposite trend is observed. As far as floristic composition is concerned, the most important species found in each habitat are almost the same regardless of habitat status. These results will be useful for a better sustainable conservation strategy for the species' populations.

Staphylococcus aureus(S. aureus) skin infections remain a prevalent public health concern worldwide, posing ongoing challenges in treatment.Uvaria chamaeroots has demonstrated significant effectiveness againstS. aureus. This study aimed to propose a dermal formulation based onUvaria chamaefor treating bacterial skin infections. The antibacterial activity was first confirmed. Tests including the time-kill test, the erythromycin outer membrane permeability test, and the ATPase/H+ proton pump inhibition test were conducted to explore the antibacterial mode of action. A cream was prepared using the phase inversion technique and subjected to quality control and senso-rheological testing. The cream was tested for antibacterial activity and skin toxicity (OECD guideline 404). Thein vivoantibacterial effect and wound-healing potential of theUvaria chamaecream were then assessed on Wistar rat. The ethanolic extract ofUvaria chamaeroot exhibited bactericidal effects on the testedS. aureusstrains. In combination with erythromycin, the extract enhanced the permeability ofS. aureus’s outer membrane while inhibiting ATPase/H+ proton pumps. The pharmaceutical quality of the produced cream revealed acceptable macroscopic conditions and satisfactory homogeneity. Antibacterial activity evaluation showed significant activity at low concentrations. The cream’s healing properties indicated a significant decrease in wound diameter (p<0.05) over time, culminating in complete healing on day 13 for the treated group, with a retraction percentage of 99.99%. These findings support the safe use ofUvaria chamaeextracts in managingS. aureusskin infections and pave the way for pre-clinical testing and potential market introduction of this cream.
