Sustainable conservation of crop wild relatives is one of the pathways to securing global food security amid climate change threats to biodiversity. However, their conservation is partly limited by spatio-temporal distribution knowledge gaps mostly because they are not morphologically charismatic species to attract conservation attention. Therefore...

Key Message Strychnos spinosa growth was less responsive than its fruit production, to tree size, protection status and climate; its fruit production increased with tree size, and more so on protected sites. Abstract Abiotic and biotic mechanisms (e.g. climate, human perturbations) are presumed to shape tree growth and reproductive performances. U...

Ricinodendron heudelotii is a wild oil tree species native to sub-Saharan Africa. It is also found in Benin. Its oil is rich in the essential fatty acids (Omega 3, 6), fat-soluble vitamins (A, D, E and K) and trace elements, essential for human health. Currently, few people know about this oil, likely explaining its almost total absence in rural ma...

... Meanwhile, heritage trees are the activation records of local ancient geography and climate change, (Lindenmayer et al., 2012;Huang et al., 2020;Nolan et al., 2020). Therefore, characteristics such as species, age, and location of heritage trees can provide important information for historical geographic studies (Atindehou et al., 2022). Heritage trees are also important urban landscapes. ...

... The different process of regeneration including germination, seedlings emergence and plant growth depend on many intrinsic and extrinsic factors (Stangeland et al., 2007;Vieira and Scariot, 2006). Abiotic and biotic factors can also shape tree growth (Avakoudjo et al. 2022). Natural regeneration is important for the sustainability of species including shea tree (Vitellaria paradoxa C.F. Gaertn., Sapotaceae), one of the major species in the agrarian landscape in West Africa dominated by agroforestry parklands (Serpentié et al. 1996). ...
... Consequently, with an increasing food demand from growing populations and the uncertainty of future climate conditions, the development of new and more resilient crop varieties is becoming a necessity, since one of the current critical challenges for agriculture is to feed nine billion world population by 2050 (Godfray et al., 2012). Moreover, resources are often very limited to glean the valuation of several species (Hounsou-Dindin et al., 2021). WOPs are generally marginalized and underutilized, due to their low yields and the risk of toxicity (Merrien et al., 2012). ...
... Further, as part of the initial steps towards the development of sustainable conservation measures for CWRs in the region, prioritisation of CWRs has been done in Benin (Idohou et al., 2013) and West Africa (Nduche et al., 2021), but studies on the effects of climate change on CWRs are nebulous in the literature for the region. To date, many studies that have been conducted in this respect have mostly been on non-CWR tree species (e.g., Favi et al., 2021;Lompo et al., 2021;Salako et al., 2021;Assogba et al., 2022), palms (Idohou et al., 2017a;Salako et al., 2019), and woody lianas (Vihotogbé et al., 2021). ...

... The discovery of markers associated with this trait can help in fast tracking, selection, and breeding of cowpea varieties with high carotenoid content in the sprouts. The results showed that the 125 accessions can be distributed into three groups, which corroborates our previous findings in the population of origin of the accessions [31]. Although the presence of population structure within the germplasm is a positive indication of genetic potential for improvement, it can be a confounding factor in testing the associations between markers and phenotypic variation [56,57]. ...

They are annual plants, herbaceous long-lived, seldom woody, with stems short or generally hails and lengthened, climbing and voluble on the right, i.e. rolled up of left on the right, while going up on a tutor [3,4,5]. Belonging to under tribe of Phaseoleae, the tribe of Phaseolineae and the order of Fabales, the beans of the Phaseolus genus have their center of origin in Central and the Southern America. ...
... e above-mentioned strategies require good quality seeds, which are propagated from trees either generatively or vegetatively. Vegetative propagation has the advantage of producing plants with traits similar to the mother plant [19,20]. e selection of mother plants as a source of plant material in vegetative propagation is pivotal in the success of S. benzoin cultivation. ...
