摘要： The article presents data on the ethnobotanical characteristics of 12 species of medicinal and food plants in the Bukhara region, where the climatic conditions are specific, hot and dry. These plants were used by the local population in ancient times and now as food and natural remedies. As a result of the study, data on the use of medicinal plants in food were collected on the basis of surveys of rural residents, housewives and elderly people of the city of Bukhara and the region. It is worth noting that due to the demand of the modern era, the study of the nutritional and therapeutic aspects of medicinal plants that grow naturally, their scientific and practical significance, determines the possibility of their use in folk medicine.

摘要： Termites are social insects that live in colonies underground. Globally, there are 3000 termite species, of which 39% are found in Africa. Termites are used as food and livestock feed in most communities of the world. In Kenya, termites are consumed by many communities, especially in the western region. Termite species diversity across different parts of the Luanda sub-county was established as there are many edible and non-edible species in the area. This study assessed the species diversity of termites in Luanda sub-county, and characterized them morphologically. Termites were sampled in Luanda sub-county using the line transect method. The collected termites were preserved in tubes containing 70% Ethanol. The preserved samples were taken to the National Museums of Kenya for morphological identification up to species level. Species richness of each habitat was analyzed for diversity (Shannon-Wiener) index and Shannon index by using Vegan package version 1.16 - 32 in R. The differences in species composition and diversity of termites were analyzed using one-way ANOVA. Morphological identification recorded seven species, namely, Macrotermes herus, Macrotermes spp1, Macrotermes sp1, Pseudocanthotermes grandiceps, Macrotermes bellicosus, Macrotermes spp2 and Pseudocanthotermes militaris. The results of this study showed that the Shannon diversity index H was 0.3606 while Simpson index D was 0.20644, which implied a high species diversity of termites in Luanda sub-county a leading producer of edible termites in Kenya.

摘要： Taking the ground cover plants of seven forest parks in Guangzhou as the research object, a total of 79 quadrats were set up, and the frequency of plant occurrences in the quadrats was counted. It belongs to 58 families and 90 genera, including 41 species of herbs, belonging to 25 families and 39 genera;54 species of woody plants, belonging to 34 families and 47 genera;1 species of vines, belonging to 1 family and 1 genus;3 species of ferns, belonging to 3 families and 3 species. The frequency of plant appearance showed that the ground cover in Guangzhou Park was dominated by herbs, with more woody plants and fewer ferns and vines. Herbaceous plants are mainly foliage plants, and there are few coleus plants;there are more coleus plants in woody plants. There are various types of ornamental plants, flexible plant collocation, and rich landscaping levels. Provide data reference for the application of ground cover plants in urban park green space landscape construction.

摘要： The distribution and form of iron and calcium compounds were studied using hydrogenation feedstock and hydrogenation products with different space velocities as the research object.The content of metallic elements,such as calcium and iron in hydrogenation feedstock,and extract samples were determined via flame atomic absorption spectrometry.The water-soluble iron and calcium species in oil samples were determined by an IC2010 high-throughput ion chromatograph.Nearly 60%-80%of the iron or calcium compounds were mainly concentrated in resins and asphaltenes.Iron and calcium compounds mainly exist in the form of oil-soluble metal species in hydrogenation feedstock and hydrogenation products.Under certain conditions of reaction temperature,pressure,and volume ratio of hydrogen to oil,when the reaction space velocity was 0.6 h^(−1),about 30%of the iron or calcium compounds were converted from oil-soluble to water-soluble species after hydrogenation.When the reaction space velocity was decreased from 1.70 to 0.60 h^(−1),the proportion of iron compounds converted from oil-soluble to water-soluble increased from 8.4%to 28%.Moreover,the proportion of calcium compounds converted from oil-soluble to water-soluble increased from 10%to 37%.This denotes that with decreasing reaction space velocity,the ratio of oil-soluble to water-soluble species increases.Water-soluble iron and calcium compounds are present in the form of inorganic salts,such as chlorate and sulfate.This study helps in understanding the removal mechanism of iron and calcium compounds and optimizing the operating conditions of residue hydrogenation.

摘要： Changes in the composition of the gut microbiota are associated with many human diseases.So far,however,we have failed to define homeostasis or dysbiosis by the presence or absence of specific microbial species.The composition and function of the adult gut microbiota is governed by diet and host factors that regulate and direct microbial growth.

摘要： Ini Local Government Area (ILGA) is the home of biodiversity, rich in many species of fauna and flora. However, anthropogenic activities carried out by the inhabitants of this area have been a threat to the ecosystem, thereby exterminating the wildlife resources. The data for this study were collected from in-depth interviews with hunters, bushmeat markets, bushmeat sellers, indirect and direct wildlife survey methods, and a semi-structured questionnaire was employed for the household survey. A multiple sampling technique was adopted. A stratified random sampling technique was utilized to stratify the study area into six strata (clans). A proportional sampling technique was used to select 11 villages. In contrast, 60 household heads were randomly selected for questionnaire administration. The study revealed seventeen (17) species of mammal, which accounted for four orders, with Rodentia being the highest (47%). Most species (94%) had the conservation status of Least Concern (LC) based on the IUCN Red List of Threatened Species. Furthermore, illegal hunting and deforestation for agriculture and infrastructural development in the area have led to the loss of wildlife habitats. Thus, a great need for conservation and management practices to protect these vulnerable mammals and their habitats is needed. Hunting laws, afforestation, and reforestation programs should be implemented.

摘要： In degraded Sahelian agro-systems, livestock manures increase agricultural production and ensure natural regeneration through their selective seed potential. Yet, this seed potential that contributes to species dissemination is still poorly known. This study aimed to determine the seed potential of different livestock ruminant manures. To this end, cattle (Bos indicus), goat (Capra hircus) and sheep (Ovis aries) manures were collected in 45 distinct enclosures in the Sahelian zone of Burkina Faso following the three seasonal periods of the year. A total of 36 species in 13 families and 26 genera was identified in the coarse fraction of the three type of manure. The most abundant seeds in the manure are those of Fabaceae-mimosoideae, Fabaceae-caesalpinoideae, Rhamnaceae and Balanitaceae. The results showed that the contribution of goats to the total seed potential was 61% against 36% for sheep and 3% for cattle. The average number of seeds was 205 seeds/Kg of manure for goats, 125 seeds/Kg for sheep and 11 seeds/Kg for cattle. Depending on the collection period, the cold-dry season contributed 70% to the total annual seed potential against 22% of the hot-dry season and 8% for the rainy season. Following the species functional traits, goat spread more seeds of woody indehiscent pods (barochores species) containing one, 4 to 10 seeds with hard cores and integuments. Sheep spread more seeds of annual legumes having dehiscent pods (autochores) and more than 10 seeds. The most abundant seeds in the manure are those of agroforestry (Vachellia nilotica, Faidherbia albida, Piliostigma reticulatum), ruderal (Ipomoea eriocarpa) or invasive (Senna obtusifolia) species. The most frequently (RI Dactyloctenium aegyptium, Eleusine indica, Corchorus tridens, Sporobolus festivus and Ipomoea eriocarpa. Taxonomic and functional characteristics of the seed potential of ruminants manures shape the regeneration traits of agro-ecosystems through selective seed dissemination.
