A portable molecular diagnostic laboratory was used to provide molecular confirmation of suspected melioidosis cases seen at Peradeniya Hospital, central Sri Lanka. Soil supernatants from rice field and rubber plantation samples also produced PCR-positive results. These procedures could be used for melioidosis field work in other remote locations.
the impacts of land cover change on the hydrologic cycle from local to regional scales are not fully understood with regard to humid tropical river basins of kerala, india. this study provides an approach to identify the effects of land cover changes on streamflow of a river basin in the humid tropical zone of kerala, india using the soil and water assessment tool (swat). the swat model was cal...
Accurate and up-to-date mapping and monitoring of rubber plantations is challenging. In this study, we presented a simple method for rapidly and accurately mapping rubber plantations in the Xishuangbanna region of southwest China using phenology-based vegetation index differencing. Temporal profiles of the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Atmospher...
Rubber tree plantations (Hevea brasiliensis) cover large areas in the tropics. In historical producing regions like South Thailand, rubber has been planted by smallholders for three successive rotations lasting a total of 75 years. Despite possible consequences on topsoil, long-term impacts repeated soil quality remain unknown. This study aims to better understand how various factors linked lan...
Regarding rubber tree plantations, researchers lack a basic understanding of soil microbial communities; specifically, little is known about whether or not soil microbial variation is correlated with succession in these plantations. In this paper, we used high-throughput sequencing of the 16S rRNA gene to investigate the diversity and composition of the soil bacterial communities in a chronoseq...
In this article we explore the issue of violence and oppression suffered by rubber-tappers in Amazonian rubber plantations, visible Miguel Ferrante´s novel Seringal. The is set Santa Rita plantation interior Acre, Brazilian Amazon, reproduces oppressive life tappers who work for owner plantation, “colonel. “Always aiming at “profit more profit” plantation´s exploits enslaves “seringueiros”, tak...
Rubber is one of the major plantation crops cultivated in Sri Lanka. It gives an environmental service apart from its economic potential. To have a continuous supply of rubber, it is vital that the balance between mature and immature rubber stands be maintained in the long run. In order to do this, at least 3% of the total area under rubber needs to be re-planted annually. However, in the recen...
Industrial forest plantations are expanding rapidly across Monsoon Asia and monitoring extent is critical for understanding environmental and socioeconomic impacts. In this study, new, multisensor imagery were evaluated and integrated to extract the strengths of each sensor for mapping plantation extent at regional scales. Two distinctly different landscapes with multiple plantation types were ...
The subfamily Zoicinae Lehtinen & Hippa, 1979 is here first recorded from China with the description of a new species in the genus Zoica Simon, 1898, Z. unciformis sp. nov. from Wild Elephant Valley (Yunnan) and a new species in the genus Lysania Thorell, 1890, L. deangia sp. nov., from a rubber plantation in Nangsang Village (Yunnan). Lysania pygmaea Thorell, 1890 is recorded for the first tim...
