    DIET COMPOSITION AND FEEDING HABITS OF CYPRINUS CARPIO (LINNAEUS 1758) (PISCES: CYPRINIDAE) IN LAKE AREKIT, ETHIOPIA
    (Wolkite University, 2025-01-30) INJIGU WENDIMU
    The diet composition and feeding habits of Cyprinus carpio (Linnaeus, 1758) were examined” “using 209 fish samples from Lake Arekit. The species' feeding patterns were determined through” “numerical indexes (frequency of occurrence and volumetric contribution) and composite indexes” “(Index of Preponderance (IOP) and Geometric Index of Importance (GIIi)). Among the 209” “specimens, 174 (83.3%) displayed a range of dietary items in their stomachs. Detritus emerged” “as the primary food source for C. carpio, followed by macrophytes, insects, and zooplankton. A” “lesser amount of phytoplankton, nematodes, and ostracods were also consumed. Based on the” “findings, C. carpio can be classified as a detri-omnivore, as it consumes benthic species like” “nematodes, ostracods, and insect larvae. Seasonal fluctuations in food item consumption were” “noted (p < 0.05), with higher intake during the rainy season and reduced consumption in the dry” “season. Significant variations in food preferences were observed among size groups (p < 0.05).” “Smaller size classes preferred foods of animal origin, such as ostracods, zooplankton, and” “insects, while macrophytes and detritus were more prevalent in the largest class. This study” “enhances our understanding of C. carpio's diet in Lake Arekit. Still, further research is necessary” “to explore the diet across the fish's lifespan and monthly, considering various environmental” “conditions.” “

    Ethnobotanical study of medicinal plants used for the treatment of human and livestock diseases in Kokir Gedebano Gutazer Welene Woreda, Gurage Zone, and Central Ethiopia
    (Wolkite University, 2025-01-30) Tariku Melis Dode
    In an ethnobotanical survey conducted designated rural and urban areas, randomly chosen sites” “were to find the most skilled practitioners who are familiar with treating human illnesses with” “traditional medicinal plants. This ethnobotanical study focuses on medicinal plants used for” “treating diseases in both humans and livestock in Kokir Gedebano Gutazer Welene Woreda,” “located in the Gurage Zone of Central Ethiopia. The study aimed to identify the diversity of” “medicinal plants and their applications in healthcare. Utilizing adescriptive research design,” “qualitative and quantitative methods were employed the study employed a combination of simple” “random sampling and purposive sampling techniques. Data collection methods included field” “visits, interviews, and participant observation. From the 34 kebeles in Kokir Gedebano Woreda,” “three kebeles were selected based on their agro-climatic zones: Ambelta Kebele lowland Tilamo” “Kebele midland, and Kentwat in highland. Research design descriptive research method was” “used because descriptive method used to describe research was qualitative and quantitative” “approaches The majority of medicinal plants were found in cultivated areas, with fewer collected” “from natural environ in average the three kebele medicinal plants of cultivated land (77.43%)” “forest (22.53%). Regard to plant families, the highest species richness consisting of 6 (8.69%)” “family solanaceae, Fabaceae, Rutaceae decrease respectively and Lamiaceae 5 (5.79%) each” “families and next families Cucurbitaceae, Rosaceae and Asteraceae 4 (4.34%) each” “families.ments. Additionally market surveys, focus group discussions, and ethnobotanical data” “analysis. Preference ranking and informant consensus factors were assessed using the” “Informant to evaluate the effectiveness of the medicinal plants across various disease” “categories. The research area's medicinal plant variety was determined by collecting and” “identifying 71 species of medicinal plants from 64 genera and 40 families. The cultivated land” “was where the majority of the medicinal plants were gathered, 54 medicinal plant species” “gathered in the study area were used to cure human ailments, while 15 were used to treat cattle” “ailments, and 13 were used to treat both. Both official and informal education systems should” “incorporate tested and validated indigenous knowledge indigenous about the traditional uses of” “plants in general and therapeutic applications.” “

    AN INVESTIGATION OF WOODY SPECIES CONTRIBUTION FOR AGROFORESTERY AND COMMUNITY MANAGEMENT PRACTICE IN MISRAK MESKAN DISTRICT OF MISRAK GURAGE ZONE CENTRAL ETHIOPIA REGIONAL STATE, ETHIOPIA.
    (Wolkite University, 2025-01-30) MOHAMMED KEDIR; Dagne Abebe (Asst. Prof)
    Woody species conservation is an issue of scientific, economic and ecological concern at global level.Woody species play many functions and make a real contribution to farmland” “protection, making them essential parts of an agroforestry system.Farmland plays significant” “role in the woody species conservation. The study was conducted to An Investigation of” “Woody Species Contribution For Agroforestery And Community Management Practice In” “Misrak Meskan District Of Misrak Gurage Zone Central Ethiopia Regional State,” “Ethiopia.Using systematic sampling techniques were representative kebele were selected” “from district . Four kebele and a total of 400 households were included in the study. Data on” “woody species were collected using a line transect across 60 plots, each measuring 40m ×” “40 m, spaced at 100 m intervals on farmland. For all woody species ≥5 cm, the diameter at” “breast height (DBH) was measured. Key materics such as important value index, density,” “dominance, and frequency were computed and analyzed. A total of 20 families and 33 woody” “species were identified and documented.The average basal area of woody species on” “farmland in study area was 0.55 m2. Farmers preferred woody species that provided for fuel” “wood, timber, shade and construction materias, with Fiaderbia albida the most favored,” “followed by Eucalyptus camaldulensis and Acacia abyssinica. The common management” “practices include coppicing and Lopping. Socioeconomic aspects like the size of the farm,” “educational background, and wealth status influenced the management of woody species on” “farmland.With 6 species, the Fabaceae family was the most represented. Fiaderbia albida., Eucalyptus camadulensis., Acacia abyssinica., Balanites aegyptiaca., and Cordia Africana.” “were the most common species, occurring in 85%, 80%, 76%, 68.33%, and 65% of the farms” “that were sampled.Overall, the study demonstrated that an agroforestry system is essential to” “the preservation of woody species.While farmers employ traditional management practice for” “wood species on their farmland,these practices required better support and extention service” “to address existing challenges.” “
