Item Open Access The effects of ambient light and temperature on moth behaviour in different South African locations(University of the Free State, 2020) Mollo, RetshedisitsweInsects, the smallest, most diverse animals in the world can be great biological indicators. Moths are one of the very few that need to be conserved in order to inform us about the environment. This study investigates how moths are affected by ambient light and temperature in three locations in South Africa. The data was collected by observing the number of moths that were present at a light source, in this case a street light, at 3 hourly intervals for several days in April and May. The data was analysed using an ANOVA test and Pearson’s correlation test, to test for the relationship between these variables and moth behaviour. There were two hypotheses. The first stated that if there was a relation between moth activity and temperature, then there would be more moths in warmer temperatures. While the second stated that if there was a relationship between moth activity and ambient light then areas with light pollution would show higher moth numbers. However the report concluded both hypotheses to be incorrect. There was no significant difference, nor a correlation between moth numbers and the variables. The implications of the study suggest that moth conservation in South Africa is something that needs to be given more attention. The people should be more aware of their impact on wildlife species by conserving them.Item Open Access Software engineering project(University of the Free State, 2020) Hassett, S. G.; Mochaki, T. M.; Phuthi, R. G.This document outlines the deliverables for the Requirements, Analysis and Design workflows of the Unified Process for the UFS COVID-19 Screening System. The UFS COVID-19 Screening System serves to automate the process of screening campus staff, student and visitors for COVID-19 symptoms before accessing the campus.Item Open Access Temperature and light effect on moth activity/numbers(University of the Free State, 2020) Seeqela, Ntsibiseng; Le Roux, AlizaIn this article, we are investigating the effects of temperature and light on moth activity or numbers. If the moths like warmer temperatures, then there will be more moths in warmer temperatures than in colder temperatures. If moths like high light pollution than low light pollution, then there will be more numbers of moths in urban areas where there is a high light pollution. There is scientific proof that moths are mostly active in warmer temperatures and in medium light pollution. The study was conducted at the sites where we are currently, at home, in different provinces which are Free State, Gauteng and KwaZulu-Natal. We observed the number of moths that came to light in different temperatures and under different levels of light pollution in 3 time intervals. In this case, the results show that the hypotheses we were testing were not supported; meaning neither temperature nor light pollution affects the number of moths. This implies that we should find out more about what affects the activity/numbers of moths.
