“…Local knowledge, utilisation, and practices (including superstitious cultures) that have evolved over the years with regards a specific plant is regarded as ethnobotany [41][42][43][44]. Most amaranth is believed to have originated from America where the Aztec and Inca scripts show early utilisation but the exact date of introduction to Nigeria remains unclear.…”

This chapter addresses the value of different Amaranthus [L.] species that have been recorded in Nigeria. These are Amaranthus blitum, A. dubius, A. caudatus, A. cruentus, A. deflexus, A. graecizans, A. hybridus, A. hypochondriacus, A. retroflexus, A. spinosus, A. thunbergii, A. tricolor and A. viridis. Although they are mostly cultivated, some are present as weeds and others are valued for their ornamental roles. Amaranthus species are the most important vegetables in some parts of Nigeria because of their leaves, succulent stem and cereal-like grains. The chapter describes their socio-cultural (ethnobotanical), ecological, economic, food and income security values as well as their production requirements. Although amaranths are stress tolerant, mesic condition and soil enrichment can increase output and nutrient composition, respectively. This work revealed that a gap exists in annual production amounts and foreign exchange earning from amaranths. It also compared the 13 species based on their proximate and phytochemical composition. Amaranths are already contributing to sustainable development and livelihood in Nigeria without established institutional support. There is a need for Nigeria to establish a vegetable centre (with the proposed name: Nigerian Vegetable Center) to maximise the potential and actual values of amaranths and other vegetable species in Nigeria.

“…The dominant woody species were Tectonagrandis with Ife Native Authority FR (98) having the highest number followed by Oba Hill FR (62) and Shasha FR (45). Ikeji-Ipetu FR (14) and Ago-Owu Forest Reserve (2) with the lowest number of Tectonagrandis. The species that followed was Gmelinaarborea with Oba Hill FR having the highest total number (36), then Shasha FR (32), Ikeji-Ipetu FR (23) and Ago-Owu FR and Ife Native Authority FR had the least (1) and (2) respectively in the demarcated plots in all the five selected forest reserves (Appendixes 1-5).…”

“…The twenty-first century is experiencing a dramatic decline in global biological diversity, which is evident in tropical regions [10] while [11] [12] reported that it is due to increasing anthropogenic impacts. Previous studies have shown that trees have undergone different levels of disturbance due to unprecedented increase in anthropogenic activities which had negatively impacted tree diversity, abundance, species composition and indigenous knowledge of tree flora and conservation [13] [14]. It has been established that timber extraction is the principal anthropogenic impact and the main cause of species extinction in terrestrial forest ecosystem [15] [16] [17].…”

Studies have shown that forest has undergone different levels of disturbance due to anthropogenic activities which impacted tree diversity, abundance and species composition. Therefore, this study examined and assessed tree diversity and abundance in five selected forest reserves in Osun State, Nigeria with a view to ascertaining the present species status for mitigation decision. Primary data include measurement of floristic composition and Key Informant Interview (KII) focusing on species inventory. A total of five sampled plots of 10 m × 10 m were demarcated in each five selected forest reserves where total enumeration of tree species within the demarcated plots were identified and classified into families, while parameters like girth (diameter at breast height) and height were measured. The result showed that the maximum height in all the selected forest reserves was 15 m. The highest total number of individual woody tree species was found in Oba Hill Forest Reserve (112). The dominant tree species were exotic species, teak (Tectonagrandis) (98 stems) and gmelina (Gmelinaarborea) (36 stems) of verbanaceae family. Indigenous woody species identified to be highly threatened and at the brinks of extinction include Terminalia Africana, Albiziazygia, Miliciaexcelsa, Anogeissusleiocarpus etc. The Shannon-Wiener index (2.499) from Ikeji-Ipeu Forest Reserve was the highest among the five selected Forest Reserves which indicated that this forest was potential biodiversity hotspot. The highest mean basal area of 3.37 m 3 and highest mean volume of 27.96 m 3 both from Oba Hill Forest Reserve showed that matured woody trees were scanty. This study revealed that anthropogenic activities had set in greatly and the forest reserves were poorly managed which had led to the reduction in number of tree diversity. This study therefore, provides baseline information for ecosystem management and control.

“…It is cultivated for its edible fruits, leaves, seeds, floral parts, and woody stem (Bioversity International, 2007;Osawaru et al, 2012). It is one of the oldest cultivated crops, presently grown in many countries of the world (Ariyo, 1993;Oyelade et al, 2003;Ogwu et al, 2016aOgwu et al, , 2016bOgwu et al, , 2017. There are several species, both cultivated and wild especially within their native (Omonhinmin & Osawaru, 2005;Osawaru et al, 2011Osawaru et al, , 2014aOsawaru et al, , 2014b.…”

This study was carried out to assess the morphological and genetic variability of seven accessions of Abelmoschus L. species using morphometric analysis and ribulose bisphosphate carboxylase large chain (RBCL) molecular markers. Using a completely randomized block design, seeds of the okra accessions were planted with three replicates each. During the developmental stage, the morphological features of the accessions were observed and recorded according to the standard descriptor for the crop. Morphologically, all the accessions exhibited a degree of similarities, albeit, at maturity, the leaf, plant height, leaf colour, and leaf shape became distinct. A cluster of the phenotypic characterization was observed at a 3.74 level of coefficient of similarity with two distinct clusters, which were predicted to be A. esculentus and A. caillei. The percentage variance of the two principal components was 55.12% and 22.69% with corresponding Eigenvalues of 4.11 and 1.69, respectively. Results of the RBCL analysis revealed genetic variability at a 0.80 level of coefficient of similarity. Two distinguishable clusters were observed. Both morphometric and genotyping results suggest that variations exist among and within the seven accessions. In conclusion, there is a need to frequently evaluate plant genetic resources held in gene banks as they may not reflect the whole range of diversity inherent in the species.
