This study examines how the violin can evoke, imitate, and transform the sonic behaviour of mosquitoes through ecological listening, biomimicry, and detailed timbral analysis. Recordings of Aedes aegypti and Anopheles gambiae flight tones were analysed to identify their narrowband frequencies, oscillatory patterns, and behavioural qualities. Through the lens of Soundscape Ecology, these insect sounds are treated as meaningful components of a wider acoustic environment rather than incidental noise. Biomimicry Theory then provides a framework for understanding how composers translate ecological behaviours, such as hovering, swarming, and darting, into violin gestures and textures. Using Spectro‑morphology, the study compares the spectral brightness, instability, and energy flow of mosquito tones with selected passages from works by Crumb, Saariaho, and Sciarrino, revealing points of acoustic and gestural convergence. Semiotic interpretation further shows how mosquito‑like timbres function as iconic, indexical, and symbolic signs, carrying cultural associations of fragility, tension, and presence. The findings introduce the concept of ecological timbre, demonstrating that environmental sound can shape instrumental expression and expand the violin’s role within a broader sonic ecology. The study contributes new insights to ecomusicology, biomimetic creativity, and contemporary music analysis. Read more

Abstract This study investigated the implications of Artificial Intelligence (AI) on information dissemination within the Broadcasting Corporation of Abia State, Nigeria. The thrusts of the study were to assess how AI technologies enhanced content creation, explore the implications of AI on Information Dissemination and audience engagement as well as identified the benefits and challenges posed by AI integration. The scope focused on the Broadcasting Corporation of Abia State which has both Radio and television sections. The researchers interacted with Broadcasting professionals within BCA and got data using focused group arrangement. Using the convenience sampling technique, 9 discussants were selected considering the objectives of the work. Diffusion of innovations and media ecology theories were the theoretical framework used. The research recommended that BCA should work assiduously hard to improve the state of its infrastructure, replace outdated equipment and train its staff on AI technology for better service delivery. Key words: Artificial Intelligence, Broadcasting, Information Dissemination, Abia State, Nigeria, Media Ecology and Innovation. Read more

An ecological study was done on weed species in two secondary forests present in Nnamdi Azikiwe University, Awka Campus and Federal college of Education Umunze, Anambra State, Nigeria. Data was collected from the two study sites which were randomly divided for adequate coverage and proper representation. Species dominance, abundance and diversity of weed species were recorded. The result of the study showed that a total of 21 weed species were recorded in Plot 1 study area which is at Nnamdi Azikiwe University, Awka campus; Pennisetum purpureum had the highest species abundance in the study site, with a total frequency of 93 and Dominance index of 28.97. Pennisetum purpureum had a relative density of while Tridax procumbens is the second most abundant with a frequency of 40 and Dominance of 7.10. Rhynchospora corymbosa shows the least in abundance with the frequency of 6. The result of Shannon wiener index for weed species in plot 1 study was 2.56 and this showed that there is high diversity of weed species in the study area. Meanwhile The result of the study in plot 2, which is at Federal College of Education Umunze showed that a total of 18 weed species were recorded; Imperata cylindrica had the highest species abundance in the study site, with a total frequency of 87 and Dominance index of 27.43 while Cypertrus rotundus is the second most abundant with a frequency of 67 and Dominance index of 10.5. Acanthus Montana shows the least in abundance with the frequency of 6 and dominance index of 1.02. The result of Shannon wiener index for weed species in plot 2 study was 2.47 and this also showed that there is high diversity of weed species in the study area. This result invariably indicates a great potential for utilization in conservation and ecological purposes. Read more

Plant growth is heavily facilitated by the extent to which many interacting climate variables remain within appropriate conditions. The Ongoing global climatic change can significantly alter conditions for plant growth, in turn upsetting ecological and social systems. While there have been substantial developments in understanding the physical features of climate change, complete studies incorporating climate, biological, and social sciences are less common. This paper used climate projections under alternative mitigation situations to show how changes in environmental variables that limit plant growth could influence ecosystems, research, policies and humans. Results showed multiple climate variables becoming limiting for plant growth, particularly in tropical areas, which resulted in considerable reductions in plant yields. Furthermore, the paper posited that reductions in plant growth due to unsuitable growing days can lead to less suitable condition for plant growth and tree mortality can trigger ecological responses, including changes in plant community composition. The paper concludes by recommending that afforestation programs should be vigorously pursued. Read more

Ecological characteristics of managed and unmanaged systems of watershed were evaluated in Amawbia southeast Nigeria. Measuring tape and pegs were used to map out an area of 1400m2 (35mx40m) in the two experimental sites. Random sampling method was applied and two coordinate AB (35m) and BC (40m) were erected in the two-study area. Quadrat method of sampling was used for counting of the species. Result from the study showed that managed plot of the watershed recorded a population of 62 individual trees and shrubs with 84 individual weeds which were mostly broad leaf. There were three individual trees in the unmanaged plots and weed population of 189 individual species which was dominated by Imperata cylindrica with highest density in the upper slopes (slope 1and slope 2). Trees and shrubs retain the basic restorative attributes of the bush fallow through nutrient recycling, fertility regeneration and weed suppression and when combined with arable cropping possess the potential to allow the farmer to crop the land for an extended period as the processes occur concurrently on the same land.
