Biography

PhD researcher specializing in plant ecology, Lesego Malekana's research focuses on understanding the spread of non-native plant species in mountain ecosystems and how invasions interact with environmental factors. She investigates the population dynamics of invasive plants across elevational gradients, aiming to identify the environmental drivers that contribute to invasion success and the recovery potential of native communities. Her work addresses key questions in invasion ecology, global change ecology, and conservation, exploring how invasive species establish and expand within mountain systems particularly under shifting climate and land-use conditions. She utilizes long-term monitoring, experimental removal techniques, and cross-regional comparisons in her studies. Malekana's research aims to understand how elevational gradients influence the persistence and spread of invasive species, as well as how native and non-native communities respond to management interventions in mountain regions.
