【Objective】 To explore the acute toxic effect of glyphosate on Pomacea canaliculata under the combined pollution of glyphosate and H2O2. 【Method】 Using the hydrostatic biological test method, adult Pomacea canaliculata with uniform growth in the field were collected, and exposed to water with different concentrations of glyphosate and similar to the average concentration of H2O2 (50 μmol·L？1) in precipitation of Guangzhou. The influences of glyphosate on some water quality indexes of P. canalicu...

Soybeans are an important crop for global food security. Every year, soybean yields are reduced by numerous soybean diseases, particularly the soybean cyst nematode (SCN). It is difficult to visually identify the presence of SCN in the field, let alone its population densities or numbers, as there are no obvious aboveground disease symptoms. The only definitive way to assess SCN population densities is to directly extract the SCN cysts from soil and then extract the eggs from cysts and count the...

Ciliwung riverbank has been a？ected by settlement occupation. Both concrete and another retaining wall system have been built to avoid ？ood and erosion to the settlement that has existed adjacent to the river. Built environment as human disturbance can trigger the change of species richness of ground vegetation in the Ciliwung riverbank of Bogor City. The research objective is to study the di？erence of ground vegetation biodiversity in three di？erent types of riverbank based on its condition: na...

Banteng, Bos javanicus, as wild cattle is a vital and importance source of germplasm in Indonesia. Various human activities currently threaten their conservation status. Nonetheless, no long-term monitoring programmes are in place for this species. Using distribution point and statistical analysis based on 46,116 camera trap days from December 2015 to January 2017, we aimed to provide habitat preferences, activity patterns and ecological data for banteng population in Ujung Kulon National Park (...

This study investigated the biodegradation of 1,1,1-trichloro-2,2-bis (4-chlorophenyl) ethane (DDT) by mixed cultures white-rot fungus Ganoderma lingzhi BMC 9057 and bacteria Pseudomonas aeruginosa. Cultures bacteria P. aeruginosa with various volumes 1, 3, 5, 7, and 10 ml (1 ml ≈ 1.53 x 109 bacteria cells/ml cultures) was added into 10 ml G. lingzhi cultures for degrading DDT. After 7 d incubation, DDT was degraded about 100% with addition of 5, 7, and 10 ml of P. aeruginosa culture into G. lin...

Landscape architecture affected by interaction between built and natural environment such as vegetation. Nowadays, landscape architects are using 3D city models for simulations, which requires highly dynamic and time-varying attributes. 3D city modelling structure has been standardized by CityGML, although researches that are related to the storing of dynamic data had been conducted for the past years, it has not been supported by any standard until this very moment. In dynamizer, it is added as...

Drought monitoring is important for the paddy planting planning. Remote sensing is one tool can be used for it. Paddy field monitoring based on the soil moisture gives much knowledge related to the water content in the soil. Soil moisture analysis in this study is using Normalized Different Water Index (NDWI), Linear Soil Moisture (LSM), and Tasseled Cap. Soil moisture change could explain based on calculation results of NDWI, Linear Soil Moisture (LSM), and Tasseled Cap Transformat...

This research examines coral reefs vulnerability which threatening its existences and functions by climate change. The ecological vulnerability in Wakatobi (Wangi-wangi, Kaledupa, Tomia, and Binongko) was assessed during Indian Ocean Dipole (IOD) event in 2016. Climate exposure was determined using sea surface temperature, chlorophyll-a concentration, and wind speed magnitude; sensitivity was determined using coral susceptibility, fish susceptibility, and macroalgae primary productivity rate; th...

The research on adaptation selection for utilization in phytoremediation of soil contaminated by crude oil using four type plants, such as Helianthus annuus, Paspalum conjugatum, Sorghum bicolor, and Tagetes erecta were conducted. The adaptability of four types of plants on crude oil contaminated soil at total petroleum hydrocarbon (TPH) level at 0, 3, and 6% were observed and evaluated to their morphological and anatomical responses. Parameters observed were vegetative growth of plants includin...
