    Perceptions on Barn Owls and Their Use in Rodent Control: A Case Study of Hwange District
    (Tropical Conservation Science, 2022) Sebele, L.; Sebele, L.; Mundy, P.; Fritz, H.
    Background and Research Aims Myths and beliefs shape the relationships that people have with different species. They lead to the protection of revered species and the persecution of negatively viewed species. In some instances, people fear these species resulting in a failure to tap into their benefits. This study investigates the possibility of using Barn Owls, a species largely linked to traditional beliefs, as a biological control for rodent pests. Methods Data was collected through a questionnaire survey. Chi-square tests were used to assess the links between socio-demographic variables and the people’s attitude towards the use of owls in rodent control. A Generalised Linear Model was used to investigate the influence of the distance of the homestead from a protected area on their perceptions of owls. Results Although most respondents acknowledged that they had a rodent problem, 41% would not use owls for their control. More females than males did not want to use owls for fear of being labelled as witches, whilst males felt owls were good for rodent control and ecosystem balance. Level of education and age did not influence people’s perceptions. People living closer to a protected area embraced the use of owls in rodent control and village of origin influenced perception of owls. Most teenagers displayed the same attitude towards owls as their mothers. Conclusion Gender and parental influence play a role in influencing the perceptions of the community on owls. There is need to further investigate the factors within a village which influence perceptions on owls. Implications for Conservation Cultural beliefs should be considered in conservation as the belief in witchcraft transcends age and education. There is need for conservation efforts to focus on improving ecological literacy of target groups to improve the conservation of feared species.

    The influence of African elephants on litter and soil nitrogen attributes in mopane woodland in Hwange National Park, northwest Zimbabwe
    (Elsevier, 2022-05-17) Maponga, T.S.; Ndagurwa, H.G.; Muvengwi, J.; Sebele, L.; Nzuma, T.M.
    Little is known about modification of nutrient fluxes through elephant-induced woodland change. We assessed litter quality, soil N attributes, and N transformations in five 20 × 20 m plots each established on sites of low, medium, and high elephant utilization categorized using dung-count surveys in three mopane woodland patches in Hwange National Park, Zimbabwe. Litter standing crop significantly declined but litter N, lignin, lignin:N, condensed tannins, and total phenols increased with increasing elephant utilization, peaking at intermediate levels of elephant utilization. Medium elephant utilization sites had more than twice the nitrate pools in low and high elephant utilization sites (p < 0.001). Ammonium concentration at low elephant utilization was lower by 65% and 92% than at high and medium elephant utilization, respectively. Soil moisture, infiltration rates, N mineralization, and nitrification decreased with increasing elephant utilization. Nitrogen mineralization and nitrification were up to four times greater in low than in medium and high elephant utilization sites. Ammonium, N mineralization, and nitrification were positively correlated to litter N but negatively correlated to condensed tannins. These results indicate that elephant-induced woodland change plays an important role in carbon and nutrient fluxes potentially increasing resources heterogeneity and reinforcing the patch dynamics of savanna.
