Item Restricted Carbon stores from a tropical seagrass meadow in the midst of anthropogenic disturbance(Elsevier, 2017) Mohammad Rozaimi; Mohammad Fairoz; Tuan Mohamad Hakimi; Nur Hidayah Hamdan; Ramlan Omar; Masni Mohd Ali; Siti Aishah TahirinSeagrass meadows provide important carbon sequestration services but anthropogenic activities modify the natural ecosystem and inevitably lower carbon storage capacity. The tropical mixed-species meadows in the Sungai Pulai Estuary (Johor, Malaysia) are impacted by such activities. In this study, we provide baseline estimates for carbon stores analysed from sediment cores.Item Open Access Heavy metals in topsoil under selected vegetable cultivation areas in Cameron Highlands, Pahang, Malaysia(Faculty of Science, Universiti Malaya, 2006) Sahibin Abd. Rahim; Zulfahmi Sali Rahman; Tukimat Lihan; Ramlan Omar; Azman Hashim; Errol Prihatino; Lai Kong MengHeavy metal contents of soil under vegetable cultivation in the Cameron Highlands were determined. Five stations selected for this purpose were Kg. Raja (forest reserve), Kuala Terla (cabbage), Tringkap (cabbage) and two stations at Blue Valley (cabbage and an abandoned tea plantation). Soil samples were collected during the harvesting season for cabbage. Soil in the tea plantation and forest were used for comparison. The mean of all of the heavy metals examined, except arsenic, were high in soil cultivated with cabbage compared to the soil under natural forest and tea plantation. The increase in heavy metal content for the agricultural area was attributed to the common practice of fertilizing, liming and pest control.Item Metadata only Ostracoda Baharu di dalam Sedimen Luar Pantai di Sekitaran Pulau Tioman, Pahang(Penerbit UKM) Noraswana Nor Faiz; Ramlan OmarItem Metadata only Ostrakod Baharu di Dalam Sedimen Luar Pantai di Sekitar Pulau Tioman, Pahang(Penerbit UKM) Noraswana Nor Faiz; Ramlan Omar
