Commercial Market

Bucephalandra sp. is a genus of aquatic plants endemic to Borneo Island, representing the Araceae family. Bucephalandra sp. is famous for its ornamental aquatic plants which are usually used in aquascaping. These aquatic plants come at fantastic prices, e.g. ±300 euros in European ornamental aquatic markets and Rp 50,000 – 700,000 in Indonesian aquatic plant markets. We collected 195 types of Bucephalandra from an ornamental aquatic plant market in Jakarta. In the market, they are sold under its commercial name. Therefore, the aim of this study is to collect and identify the species of all Bucephalandra types in the aquatic plant commercial market. These species that we identified are based on botanical taxonomist identification in the Herbarium Bogoriense Department Botany – Research Centre for Biology – Indonesian Institute of Science (LIPI) Cibinong. The result of this study is from our collection (195 types) of which 102 types are Bucephalandra Motleyana Schott species and 90 types are the other species of Bucephalandra.

High Sediment

Under the influence of increasing air temperatures, dormant seeds of wetland plants and eggs of microfauna may be subjected to increased sediment temperatures that adversely affect their capacity to germinate or hatch, while the wetland is in its ‘dry’ phase. We conducted a mesocosm experiment to investigate the influence of sediment temperature on the emergence capacity of dormant seeds and eggs. Dry wetland sediment was exposed to temperatures ranging from –180 to 150°C. After re-wetting, the taxon richness and abundance of communities that developed were assessed. Both aquatic plants and microfauna emerged from the seed bank at sediment temperatures lower than 50°C. However, the composition of the microfaunal community was altered once temperatures exceeded 40°C and germination of aquatic plants ceased once temperatures exceeded 50°C. These results suggest that changes to sediment temperature during the dry phase of wetlands may play an important role in influencing communities of wetland aquatic plants and microfauna. Modelled sediment temperature data indicated that minimum sediment temperature could exceed 40°C for extended periods of time under existing climate-change scenarios by 2070. An increase in the occurrence and duration of such temperatures may threaten the abundance and diversity of wetland microfauna and aquatic-plant communities.

Aiming to identify the populations of aquatic plants present in the Porto Primavera reservoir and evaluate the behavior of Hydrilla verticillata colonization of this water body a survey was carried out in 2007. The data was based on presence or absence, only were assessed the presence or absence of the species and the data were subjected to cluster analysis to establish differences in distribution and occurrence of populations. The community of aquatic plants showed 24 species distributed in 16 botanical families. Cyperaceae and Pontederiaceae were the most representative in terms of species richness. The submerged macrophyte Hydrilla verticillata showed the highest frequency of occurrence in the water body, showing a different behavior from the other populations of the water body. Species like Eichhornia crassipes, Eichhornia azurea, Typha dominguensis and Oxycaryum cubense also showed different behavior in relation to other populations within the community, forming large populations in lagoons and backwater areas.

Purification Efficiency

The effluent from activated sludge treatment of petroleum wastewater was treated with the aid of a ponding system using aquatic plants (Water Hyacinth, Chlorella, Reed). A good result was obtained in this study. Pilot pond system shows that the purification efficiency depends on the residence time of about 14 days. The petroleum removal waa 97-98 %, the COD removal was from 88-93 %. The dissolved oxygen amount (with Chlorella) increased from 0.7 mg/l to 9.8 mg/l and the pH increased from 6.9 to 8-8.6. The application of 3 step biological pond with the use of Water Hyacinth, Chlorella, Reeds for post treatment of petroleum wastewater is appropriate in Vietnam.

Emergent Species

Experimental results demonstrate bow small differences in depth and water regime have a significant affect on the accumulation and allocation of nutrients and biomass. Because the performance of aquatic plants depends on these factors, an understanding of their influence is essential to ensure that systems function at their full potential. The responses differed for two emergent species, indicating that within this morphological category, optimal performance will fall at different locations across a depth or water regime gradient. The performance of one species was unaffected by growth in mixture, whereas the other performed better in deep water and worse in shallow.

The aquatic plant Pistia stratiotes L. is environmentally hazardous and requires effective methods for its utilization. The harmfulness of these plants is determined by their excessive growth in water bodies and degradation of local aquatic ecosystems. Mechanical removal of these plants is widespread but requires fairly resource-intensive technology. However, these aquatic plants are polymer-containing substrates and have a great potential for conversion into bioenergy. The aim of the work was to determine the main patterns of Pistia stratiotes L. degradation via granular microbial preparation (GMP) to obtain biomethane gas while simultaneously detoxifying toxic copper compounds. The composition of the gas phase was determined via gas chromatography. The pH and redox potential parameters were determined potentiometrically, and Cu(II) concentration photocolorimetrically. Applying the preparation, high efficiency of biomethane fermentation of aquatic plants and Cu(II) detoxification were achieved. Biomethane yield reached 68.0 ± 11.1 L/kg VS of Pistia stratiotes L. biomass. The plants’ weight was decreased by 9 times. The Cu(II) was completely removed after 3 and 10 days of fermentation from initial concentrations of 100 ppm and 200 ppm, respectively. The result confirms the possibility of using the GMP to obtain biomethane from environmentally hazardous substrates and detoxify copper-contaminated fluids.

Viable Seeds

In temporary ponds, seed germination largely determines how well aquatic plant assemblages recover after dry periods. Some aquatic plants have terrestrial morphotypes that can produce seeds even in dry years. Here, we performed an experiment to compare germination patterns for seeds produced by aquatic and terrestrial morphotypes of Ranunculus peltatus subsp. saniculifolius over the course of five inundation events. During the first inundation event, percent germination was higher for terrestrial morphotype seeds (36.1%) than for aquatic morphotype seeds (6.1%). Seed germination peaked for both groups during the second inundation event (terrestrial morphotype: 47%; aquatic morphotype: 34%). Even after all five events, some viable seeds had not yet germinated (terrestrial morphotype: 0.6%; aquatic morphotype: 5%). We also compared germination patterns for the two morphotypes in Callitriche brutia: the percent germination was higher for terrestrial morphotype seeds (79.5%) than for aquatic morphotype seeds (41.9%). Both aquatic plant species use two complementary strategies to ensure population persistence despite the unpredictable conditions of temporary ponds. First, plants can produce seeds with different dormancy periods that germinate during different inundation periods. Second, plants can produce terrestrial morphotypes, which generate more seeds during dry periods, allowing for re-establishment when conditions are once again favorable.

This introduction provides context for a collection of articles that came out of a research symposium held at the Science Museum's Dana Research Centre in 2018 for the ‘ Demons of Mind: the Interactions of the ‘Psy’ Sciences and Cinema in the Sixties' project. Across a range of events and research outputs, Demons of the Mind sought to map the multifarious interventions and influences of the ‘psy’ sciences (psychology, psychiatry, and psychoanalysis) on film culture in the long 1960s. The articles that follow discuss, in order: critical engagement with theories of child development in 1960s British science fiction; the ‘horrors’ of contemporary psychiatry and neuroscience portrayed in the Hollywood blockbuster The Exorcist (1973); British social realist filmmakers' alliances with proponents of ‘anti-psychiatry’; experimental filmmaker Jane Arden's coalescence of radical psychiatry and radical feminist techniques in her ‘psychodrama’ The Other Side of the Underneath (1973); and the deployment of film technologies by ‘psy’ professionals during the post-war period to capture and interpret mother-infant interaction.

Ex-situ culture studies of five selected aquatic macrophytes, namely Nymphaea nouchali Burm. f., Enhydra fluctuans Lour., Ipomoea aquatica Forsk., Hygroryza aristata (Retz.) Nees ex Wight & Arn. and Limnocharis flava (L.) Buch. were carried out. Comparing the biochemical composition of the above mentioned five aquatic macrophytes, on an average, Enhydra fluctuans was found to contain highest amounts of proteins (18.20%) and Ipomoea aquatica contains highest amounts of carbohydrate (58.60%). Lowest amounts of proteins (14.35%) were recorded in Hygroryza aristata and Limnocharis flava. On the other hand lowest amounts of carbohydrates were obtained in Nymphaea nouchali. Ipomoea aquatica contained highest amounts of energy (321.23 kcal) and lowest amount was observed in Limnocharis flava. The five aquatic plants were low in fiber, fat and also in ash. Among all the five aquatic macrophytes, highest values of calcium and phosphorus were found to be present in Limnocharis flava and iron was highest in Nymphaea nouchali. Lowest values of calcium and phosphorus were present in Ipomoea aquatica and lowest amount of iron was present in Limnochris flava. The present study demonstrated that, these five aquatic macrophytes are the important sources of carbohydrate, protein and minerals, which are suitable for incorporation in human diet and feed also.
