Del.) is an indigenous fruit tree, common in the arid and semi-arid lands of Africa. Its fruits, available in the height of the dry season, contain edible pulp which is an important food for both humans and livestock. Balanites kernel is a source of highly regarded edible and medicinal oil. Both the fruits and oil are trade items in the west Nile sub-region of Uganda. Because of its growing importance as a source of food and income for dryland communities, an assessment of the physico-chemical characteristics and fatty acid profile of kernel oil in Uganda was carried out. Balanites fruit samples were collected from Katakwi, Adjumani and Moroto districts; representing the Teso, West Nile and Karamoja tree populations, respectively.

  • Camel Forage Variety in the Karamoja Sub-Region, Uganda
    Salamula et al. Pastoralism: Research, Policy and Practice (2017) 7:8 Pastoralism: Research, Policy DOI 10.1186/s13570-017-0080-6 and Practice RESEARCH Open Access Camel forage variety in the Karamoja sub- region, Uganda Jenipher Biira Salamula1*, Anthony Egeru1,2, Daniel Knox Aleper3 and Justine Jumba Namaalwa1 Abstract Camels have the potential to increase the resilience of pastoral communities to the impacts of climate variability and change. Despite this potential, there is limited documentation of the camel forage species, their availability and distribution. The study was conducted in Karamoja sub-region in Uganda and involved assessment of vegetation with intent to characterize the range of forage species available for camels in the region. The camel grazing area was stratified based on land cover types, namely woodland, bushland, grassland and farmland using the Amudat and Moroto district vegetation maps. Vegetation plots measuring 20 m × 20 m were mapped out among the land cover types where species identification was undertaken. In addition, a cross-sectional survey involving 52 camel herders was used to document the camel forage species preferences. Shannon and Simpson diversity indices as well as the Jaccard coefficient were used to measure the species richness, relative abundance, diversity and plant community similarities among the land cover types. Results showed high species richness and diversities in the bushland and woodland land cover types. Plant communities in the woodland and bushlands were found to be more similar. A wide range of plant species were reported to be preferred by camels in the study area, that is 63 in Amudat and 50 in Moroto districts.

  • Inter Simple Sequence Repeat Markers to Assess Genetic Diversity
    www.nature.com/scientificreports OPEN Inter simple sequence repeat markers to assess genetic diversity of the desert date (Balanites aegyptiaca Del.) for Sahelian ecosystem restoration Selouka Mint Abdelaziz1,2, Leila Medraoui1, Mohammed Alami1, Ouafae Pakhrou1, Meryem Makkaoui1, Ali Ould Mohamed Salem Boukhary2 & Abdelkarim Filali‑Maltouf1* Drought and desertifcation are the major environmental constraints facing the Sahelian agro- ecosystems for decades. Assessing genetic diversity of native tree species is critical to assist ecosystems restoration eforts. Here we describe genetic diversity and structure of seven Balanites aegyptiaca L. natural populations distributed across the Sahelian‑Saharan zone of Mauritania using 16 polymorphic ISSR primers. These generated 505 polymorphic bands. Polymorphism information content (PIC) varied from (0.13–0.29) with an average 0.23, marker index (MI) averaged 7.3 (range 3.3–10.3) and resolving power (RP) ranged from (4.53–14.6) with an average 9.9. The number of observed alleles (Na) ranged from (0.62–1.39), Efective number of alleles (Ne) varied from (1.26–1.37), Shannon’s information index (I) ranged from (0.25–0.36). AMOVA analysis showed that 80% of the genetic variation was fned within populations, which is supported by a low level of genetic diferentiation between population (GST = 0.21) and an overall estimate of gene fow among populations (Nm = 1.9). The dendrogram based on Jaccard’s similarity coefcient and the structure analysis divided the seven populations into two main clusters in which two populations from the Saharan zone were grouped. Our results provide baseline data for genetic conservation programs of this Sahelian neglected crop and with an important econ-ecological role.

Box 6096, Khartoum, Sudan; Corresponding author, E-mail: [email protected] Accepted January 15, 2013 Desert date ( Balanites aegyptiaca ) is a widely distributed natural tree in Sudan and many other tropical countries especially in Africa and Asia. The tree is rich in useful products with multi-uses in rural lives and industry. Hence, the current laboratory study was aimed to evaluate the insecticidal potentiality of B. aegyptiaca against the third instar larvae of Trogoderma granarium . Water and organic solvents extracts of leaves, branches and seeds were tested at different concentrations. The extracts yields, mortality and repellent effects and the consequent damage on sorghum grains were the main parameters studied. The highest extractive yield (56.7%) was obtained by the seeds hexane extract (oil). This extract also scored better mortality effects than the other treatments. The highest concentrations (2.5% and 5%) of oil showed comparably the best significant effects since the second day of treatments, and revealed progressive activities with exposure time. The latter concentration (5%) manifested 72.7% repellency for the insect larvae, and saved sorghum grains damage by 30.0% within 45 days post treatments. Nevertheless, the highest savings of grains (50.0%) that attained by the water seeds extract in spite of its inferior mortality results may needs to be clarified in further research.
