The first meeting of authors for a new global assessment of invasive alien species and their control for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), was held recently in Japan.
Clearing the invasive alien tree Port Jackson (Acacia saligna) doesn't necessarily lead to the recovery of native plant communities because secondary invaders may be dominant and persist up to three years after clearing at levels similar to, or higher than the first year after clearing.
A large diversity of animals can use behavioural thermoregulation, which is the selection of microhabitats such as shade and sun patches or changes in activity patterns within days or between seasons, to maintain preferred body temperatures.
Invasive species offer many important challenges to society. Their presence is intrinsically linked to human actions, but their impacts are felt across a wide range of environmental and socio-economic levels.
Drs Richard Dean (DST/NRF Centre of Excellence: Percy FitzPatrick Institute of African Ornithology), Colleen Seymour (South African National Biodiversity Institute), Grant Joseph (University of Venda) and Stefan Foord (C·I·B Core Team Member) reviewed current literature to explore wildlife responses to roads at the arid end of the spectrum.
