An IBER Seminar entitled “Differential impacts o $An IBER Seminar entitled “Differential impacts of Acacia invasion on nutrient fluxes in two distinct Bornean lowland tropical rain forests” was presented by Dr Salwana Md Jaafar (IBER, UBD) on 18 January 2023. Invasive Acacia can alter nutrient cycling processes in forest ecosystems, particularly affecting total litterfall production and litter decomposition patterns. This study examined the effects of exotic Acacia mangium species on total litterfall production, nutrient concentrations in leaf litterfall fractions, leaf litter decomposition and nutrient release in lowland heath and mixed dipterocarp forests in Brunei Darussalam, Borneo. Habitats invaded by Acacia exhibited higher total litterfall production, increased leaf litter concentrations of nitrogen, potassium and calcium, increased addition of all nutrients measured in litter (nitrogen, phosphorus, potassium, calcium and magnesium, especially in the Acacia-invaded mixed dipterocarp forest (AMDF) and nitrogen and potassium in Acacia-invaded heath forest (AHF)), reduced nitrogen and potassium use efficiencies in AHF and, reduced stand-level nitrogen and calcium use efficiencies in AMDF. Litter decomposition rates and nutrient release were lower in AMDF than in the three other habitats. The significantly higher total litterfall production coupled with higher nutrient addition in the two Acacia-invaded habitats are expected to progressively increase the abilities of these habitats to produce large quantities of nutrient-rich litter and will likely eventually lead to an enrichment of nutrients in the soil, thus facilitating further invasion by Acacia, particularly in the MDF. Dr Salwana Jaafar is an Assistant Lecturer/Postdoctoral Researcher in Tropical Ecosystem Ecology at the Institute for Biodiversity and Environmental Research (IBER), Universiti Brunei Darussalam. #iberseminar #iber #ubd #acacia$
