Abstract. Ruziman HH, Ismail A, Mohti A, Radzun KA, Pardi F. 2023. Toward healthy urban streets: Diversity of roadside tree species in industrial area of Shah Alam, Selangor, Malaysia. Biodiversitas 24: 2674-2681. Shah Alam, one of the biggest cities in Selangor has undergone a significant transformation with numerous developments to cater the needs of the ever-growing population. However, the rapid urbanization and massive infrastructure developments have indirect effects on landscape patterns and roadside tree diversity. Hence, this study was conducted to assess the species richness and diversity of roadside trees in Shah Alam, Selangor. All trees with height of 1 meter and above in Section 15 and 16 were measured and identified as referred to the Landscape Department of Shah Alam City Council (MBSA) computerized database. The data were analyzed for their taxonomic composition and species diversity. A total of 5,523 trees were recorded where 4,087 trees occurred in Section 15 and 1,426 trees in Section 16. Fabaceae was the most dominant family in both sections in which three leading species, i.e. Peltophorum pterocarpum (DC.) Backer ex K.Heyne, Pterocarpus indicus Willd. and Roystonea regia (Kunth) O.F.Cook, accounted for 14.7% of the planted trees. Section 15 was relatively higher in taxonomic composition with 11 families and 25 species than Section 16, with 8 families and 18 species. The values for species diversity index were considered high in both sections with 8.37 despite the environmental impact from the industrial activities. Thus, it is suggested that future research should include the potential risks of biodiversity loss for proper management practices in urban settings.

Abstract. Ramli R, Zulkifli NFD, Ismail A, Pardi F. 2025. Monsoonal effects on meiofaunal assemblages in Pulau Tuba Mangroves, Langkawi, Malaysia. Biodiversitas 26: 4694-4705. Mangrove ecosystems are dynamic coastal habitats that support diverse and functionally important benthic communities, including meiofauna. This study investigates the spatial and temporal patterns of meiofaunal assemblages in the mangrove sediments of Pulau Tuba, Langkawi, Malaysia, in relation to monsoonal-driven environmental changes. Sediment and porewater samples were collected from four stations (MG1-MG4) in June 2023 and November 2023 to represent the Southwest Monsoon and Northeast Monsoon, respectively. Meiofauna were collected and classified to major taxa, while various environmental parameters were quantified, including salinity, temperature, pH, dissolved oxygen, organic matter content, sediment grain size, and composition. A total of nine meiofaunal groups were recorded, namely Sarcomastigophora, Copepoda, Rotifera, Oligochaeta, Halacaroidea, Polychaeta, Ostracoda, Kinorhyncha, with Nematoda dominated (>90%) in both seasons. Meiofaunal density was significantly higher during the Southwest Monsoon (Paired t-test, p<0.05). Diversity indices showed low species diversity, with dominance by a few groups. Multivariate analyses revealed that seasonal variation had a greater influence on community structure than spatial differences. Principal Component Analysis and Distance-based redundancy analysis identified salinity, temperature, organic matter, and dissolved oxygen as the key environmental drivers structuring meiofaunal communities. These findings add to the limited body of research on Malaysian and tropical mangrove meiofauna and provide observational evidence that may inform conservation planning, sustainable management, and policy discussions aligned with SDGs 14 and 15.

Abstract. Ruziman HH, Mohti A, Yo NESC, Pardi F. 2024. Comparative assessment of carbon dioxide (CO2) absorption capacities in Koompassia malaccensis and Hopea nervosa in Tekam Forest Reserve, Pahang, Malaysia. Nusantara Bioscience 16: 185-191. Trees, the dominant life form in forests, are essential in the functioning of the terrestrial biosphere, especially for the carbon cycle of the ecosystem. This study aims to assess CO2 absorption by two forest production species: Koompassia malaccensis Maingay and Hopea nervosa King. The experiment was carried out in an acrylic box, and the variation of carbon dioxide concentration, humidity, light, and temperature was measured using a Carbon Dioxide, Light, Temperature, and Humidity (CLTM) sensor. The experiment was conducted in an open area from 7:30 am to 6:30 am the next day (23 hours). The results showed that H. nervosa absorbed more CO2 (71.13 ppm/hour) than K. malaccensis (51.54 ppm/hour), thus promoting its ability to address climate change in the microenvironment. As for the relationship between carbon dioxide absorption and photosynthesis variables, both species show a positive correlation between CO2 absorption and humidity. In contrast, light and temperature were very weakly correlated to CO2. Therefore, it was identified that H. nervosa (Dipterocarpaceae) and K. malaccensis (Fabaceae) are tree species with high CO2 absorption capacity and thus can be considered suitable trees for replanting, especially in light of carbon mitigation initiatives.
