Gonadal assessment of adults demonstrated the presence of reproduction capable specimens. The concurrent occurrence of mature adults and juvenile fish demonstrated establishment. Locality records indicate that P. disjunctivus has already spread between two rivers through an inter basin water transfer. Using a unified framework for invasions this invasion was categorized as a self-sustaining population in the wild with individuals surviving and reproducing a significant distance from their original point of introduction. Containment is suggested as potential management strategy.]]> Thu 11 Jul 2024 09:23:19 SAST ]]> Effect of the relative humidity on the fibre morphology of polyamide 4.6 and polyamide 6.9 nanofibres https://vital.seals.ac.za/vital/access/manager/Repository/vital:51004 Mon 16 May 2022 13:10:16 SAST ]]> Reconstructing the history of introduction and spread of the invasive species, Lantana, at three spatial scales in India https://vital.seals.ac.za/vital/access/manager/Repository/vital:43687 Fri 10 May 2024 15:11:57 SAST ]]>
