The present investigation has been conducted to assess the status of physico-chemical parameters as well as the concentrations of some selected heavy metals to understand the present scenario of water quality at Perak River basin, Malaysia. The temperature, turbidity, pH, EC and DO values of all the examined samples have been within the range of 25.0 to 30.5 0C, 39.5 to 168.00 NTU, 6.8 to 7.33,...

Alshari et al. (2023; Endang Species Res 50:311-313) were able to collect 3 Fluvitrygon kittipongi specimens from the Pahang River, which not available us at time of our study (Lim & Then 2022; 48:43-50). The cytochrome c oxidase I (COI) sequences (or haplotypes) these stingrays identical each other but differed haplotypes Perak River specimens. result 100% similarity between COI rays and e...

Stable isotope analysis has been used extensively to establish trophic relationships in many ecosystems. Present study utilised stable isotope signatures of carbon and nitrogen to identify trophic structure of aquatic food web in river and rice field ecosystems in Perak, northern peninsular Malaysia. The mean δ13C values of all producers ranged from -35.29 ± 0.21 to -26.00 ± 0.050‰. The greates...
