Global warming or often referred to as global warming is a form of imbalance of ecosystems on earth due to the process of increasing the average temperature of the atmosphere, sea, and land on earth. The impact of global warming can make agricultural plants flower faster while pollinating insects are not ready so that the reproductive cycle is disrupted. Studying temperature changes as a result of global warming on an organism can be represented by an altitude gradient. The study aims to determine the effect of temperature changes on the phenology of winged bean plants (Psophocarpus tetragonolobus) which is described by the gradient of altitude and to determine the diversity of pollinator insects. The independent variable in this study is the difference in the gradient in elevation of the place, while the dependent variable is the phenology of the development of winged bean flowers and pollinator insects. The results of the study of abiotic factors showed that air temperature and sunlight intensity decreased in line with the increase in altitude from the surface of the seawater, while the humidity increased. The phenological analysis of winged bean plants showed the influence of altitude on plant height, number of leaves and branches, time of the first appearance, number of flowers and flower size as well as the diversity of pollinator insects.

The research about rhizofiltration of Pb in several species of aquatic plant had been conducted in a greenhouse of Biology Faculty, Jenderal Soedirman University. The aims of this research were to evaluate the aquatic plant species which has Pb accumulative characteristic and to determine Pb concentration tolerated by those plants. This research was used experimental method with split plot design. The main plot was kind of aquatic plant of Hydrilla verticillata (L.f), Pistia stratiotes L, and Salvinia molesta D.S.Mitchell. The Pb (NO3)2 concentrations of 0, 5, 10, 15 mg/l were as sub plot. Each treatment was replicated for 3 times. The parameter observed were biomass (raw weight and dry weight), the Pb absorbed whether in root and shoot, and chlorophyll content. Data collected were analyzed using F test continued by LSD. The result of this research showed that both Pistia and Salvinia planted in 10 mg/l media were able to accumulate high Pb concentration. However, Pistia were able to accumulate Pb concentration mostly in root and only part be translocated in shoot. Whereas Salvinia was able to translocate Pb concentration in shoot higher than those in of Pistia. The implications of these results for rhizofiltration are discussed.

Cinnamomum sintoc Blume is an endangered species experiencing an ongoing decline due to overharvesting; in- and ex-situ conservation efforts are urgently needed to ensure its survival. We performed a detailed assessment of the flowering and fruiting phenology of C. sintoc in a lowland forest in West Java, Indonesia. We aimed to relate the duration of each phenological phase to environmental factors including elevation, humidity, temperature, and slope, as well as the orientation of the flowers. A total of 30 trees were sampled from three elevation ranges (500–700, 700–900, and 900–1,100 m). We found that C. sintoc requires approximately 40 days to complete flowering and an additional 82 days to produce mature fruit. The period from flower initiation to fruit ripening spans 4 months, from late July to early November. Flowers that are east-facing developed mature fruit more rapidly than those facing other directions, and the shortest flowering and fruiting phenological period was observed for east-facing flowers at 700–900 m. These results provide a baseline for studying phenological shifts in C. sintoc, and could inform seed harvesting efforts for conservation projects in the study area of Gunung Cermai National Park.
