Several hundred species are hunted for wild meat in the tropics, supporting diets, customs, and livelihoods of millions people. However, unsustainable hunting is one most urgent threats to wildlife ecosystems worldwide has serious ramifications people whose subsistence income tied meat. Over past 18 years, although research efforts have increased, scientific knowledge largely not translated into action. One major barrier progress been insufficient monitoring evaluation, meaning that...
Wild animals play an integral and complex role in the economies ecologies of many countries across globe, including those West Central Africa, focus this policy perspective. The trade wild meat, its diets, have been brought into as a consequence discussions over origins COVID-19. As result, there calls for closure China's "wet markets"; greater scrutiny wildlife general; spotlight has placed on potential risks posed by growing human populations shrinking natural habitats animal to...
The COVID-19 pandemic has brought humanity's strained relationship with nature into sharp focus, calls for cessation of wild meat trade and consumption, to protect public health biodiversity.1Yang N.

Summary The cultivation and dissemination of alien ornamental plants increases their potential to invade. More specifically, species with bird‐dispersed seeds can potentially infiltrate natural nucleation processes in savannas. To test (i) whether invasion depends on facilitation by host trees, (ii) propagule pressure determines probability, (iii) are better facilitators fleshy‐fruited than indigenous species, we mapped the distribution planted inside a military base, compared this native...
Activities and roles in value chains of forest products the Congo Basin are highly gendered, varying with product's characteristics, segment chain customary regulations norms. High-value primarily male-harvested when rules govern tenure access, enabling men to exert control. Whilst non-timber (NTFPs) important cash sources for both sexes, women tend use more their harvest domestic consumption, while sell a greater proportion. Interventions by research development organisations, NGOs projects...
Abstract Efforts to preserve, protect and restore ecosystems are hindered by long delays between data collection analysis. Threats can go undetected for years or decades as a result. Real‐time help solve this issue but significant technical barriers exist. For example, automated camera traps widely used ecosystem monitoring it is challenging transmit images real‐time analysis where there no reliable cellular WiFi connectivity. We modified an off‐the‐shelf trap (Bushnell™) customised existing...
Determining the potential range of invasive alien species under current conditions is important. However, we also need to consider future distributions scenarios climate change and different management interventions when formulating effective long‐term intervention strategies. This paper combines niche modelling fine‐scale process‐based define regions at high risk invasion simulate likely dynamics landscape scale. Our study Schinus molle (Peruvian pepper tree; Anacardiaceae), a native...
NTFPs are often presented as a major contributor to livelihoods, sources of food and cash, particularly for rural communities. There few data available in Gabon confirm this common assertion. This study was conducted on 127 households 14 villages around two timber concessions the south-eastern south-western regions period one year. Conventional socio‐economic survey tools such focus group discussions, census semi-structured interviews with were used gathering data. Results reveal that people...
The potential of forest foods to address malnutrition, food insecurity and poor dietary intake is increasingly being recognized. However, most existing data presents average results proximate analysis, overlooking the opportunities document how contribute nutrition, security intake. In this study, was estimated using HFIAS score while FFQ recalls among 720 households in around six logging concessions Cameroon, DR Congo Gabon. There a high diversity forests consumed, with (FFCS=16.2)...
Climate change is rapidly disrupting forest and agroforest ecosystems, with rising temperatures, extreme events, species shifts threatening their health resilience. Proactive management strategies are crucial to ensuring the continued provision of essential ecosystem services. Despite significant progress in forest-climate research, gaps remain integrating monitoring data, modeling future conditions, developing context-specific adaptation strategies. International cooperation essential, as...
Many tropical tree species have buttresses at the standard breast height (1.3 m above ground) of diameter measurement, with a presumable role in improving nutrient acquisition or anchorage ground (Newbery et al . 2009, Richter 1984). Measuring using dendrometrical tools such as callipers graduated tapes, which require that cross-section trunk has convex shape, is then impossible (Nogueira 2006). The recommended method this case to measure buttress (DAB), thus possibly leading biased...
Predicting the biomass of a forest stand using inventory data and allometric equations involves chain propagation errors going from sampling error to tree measurement error. Using set 101 trees in tropical rain Gabon, we compared two sources error: due choice equation, assessed Bayesian model averaging, when is calculated volume rather than directly weighed. Differences between resulted between-equation about 0.245 for log-transformed with residual within-equation 0.297. Because leveled off...
Abstract Schinus molle (Peruvian pepper tree) was introduced to South Africa more than 150 years ago and widely planted, mainly along roads. Only in the last two decades has species become naturalized invasive some parts of its new range, notably semi‐arid savannas. Research is being undertaken predict potential for further invasion Africa. We studied production, dispersal predation seeds, seed banks, seedling establishment relation land uses at three sites, namely ungrazed savanna once used...
Abstract Tropical rain forests worldwide are affected by anthropogenic disturbances, and secondary that develop afterwards often dominated pioneer tree species, but the consequences of different disturbances on nutrient cycling poorly understood. Because most in tropical occurs through litterfall soil organic layer, we measured a widespread dominant tree, okoume ( Aucoumea klaineana , Burseraceae) Gabon, one forest previously disturbed logging another agriculture. Litterfall trees, over 14...
Abstract Interventions in Africa designed to stop biodiversity decline have often failed because they were based on a top‐down approach management and focused enforcing restrictive rules imposing bans. They equally misaligned with the values needs of local actors. This paper presents an African perspective discourse regarding bushmeat crisis shows that goes beyond being source livelihood, having multifaceted use must be considered when designing interventions. We show current conservation...
The trees and non-timber forest products (NTFPs) of the Congo Basin play a key role in alleviating food insecurity among millions people around world. Although many studies have been conducted both nationally regionally on issues Basin, little is known effects timber exploitation household statues dependent communities this region.

Traditional, forest resource-dependent livelihoods face multiple challenges. In Gabon, bushmeat provides food and income for rural communities. This study investigates how villagers believe livelihood practices dependence on changed over the last decade if alternative generating strategies can be sustainable. Our results show that remote villages near Moukalaba Doudou National Park hardly practices. Less Tchibanga experienced declining hunting revenues are switching to alternatives. Villages...
Wild meat has long been used as a source of food and income by many communities across the tropics (Ingram et al., 2021). Recently, however, growing human populations increasing commercial trade to urban markets have driven up demand prices for wild products led unsustainable levels wildlife harvesting in places (Coad 2019). Overexploitation linked significantly reduced (Benítez-López 2017) increased extinction risk medium large-bodied species (Dirzo 2014). The loss these poses security...
