| dc.description.abstract | Gullele Botanic Garden contains diverse types of invertebrates. The diversity, distribution, frequency, density and abundance of these invertebrates were investigated using 28 quadrats which were located at different habitat types. The study found that Gullele Botanic Garden support the presence of invertebrates in large quantity in mixed forest habitat. A total of 2854 invertebrate specimens belonging to 42 families were collected and recorded in the Gullele Botanical Garden. Higher diversity and evenness of invertebrates were observed in the mixed foresthabitat. On the other hand, the least evenness and diversity of invertebrates was observed in the grassland forest habitat in the study season. Based on jaccard's similarity index, the highest similarity was observed between mixed forest and grassland forest habitats.. The lowest similarity was observed between natural forest habitat and artificial forest habitat. Abundance of food on species of vegetation, stability of the habitats, human activities and settlement inside determined invertebrate diversity in the study areas.During data collection in Gullele Botanic Garden, careful observation showed that invertebrates had both positive and negative effect for humans, animals and insects. The positive effects were increasing soil fertility(earthworms),nutrient cycling(ants),increasing the rate of soil nutrient cycling(beetles) and indicators of environmental change and habitat disturbance(insects). Conversely, the negative effects were plant drying(termites) and attacking roots,trunks,stems,leaves, flowers ,seeds ,fruits and saps of vascular system(phytophagous invertebrates). | en_US |
