AbstractTo elucidate the details of both the current status of contamination and the accumulation of organotin compounds (OTs) in mangroves in coastal ecosystems, we determined the concentrations of butyltin compounds (BTs) and phenyltin compounds (PTs) in sediment and mangrove leaves collected from mangrove forests in Merambong and Tinggi Island, Malaysia. Butyltins were detected in all sediment samples collected from both regions, whereas PTs were not detected. The levels of tributyltin (TBT) compounds in the sediment samples were lower than those from previous studies conducted in Malaysia and at other sites in South-east Asia. In both Merambong and Tinggi Island, the average proportions of dibutyltin (DBT) and monobutyltin (MBT), which are degradation products of TBT, were ~70%. This result suggests that the input of TBT has decreased in Malaysia. The proportions of DBT and MBT in the sediment from Merambong were higher than those from Tinggi Island. The concentrations of TBT in mangrove leaves from Tinggi Island were significantly higher than those from Merambong. MBT was the most dominant type among the BTs in mangrove leaves from both Merambong and Tinggi Island. The ratios of the BTs burden in mangrove leaves to the BTs concentration in sediment from Merambong and Tinggi Island averaged 3.1 and 6.2, respectively. Among the values of BTs, the MBT values were found to be the highest in both regions.

Three new whitefly species, Trialeurodes rex Martin sp. nov., T. bruneiensis Martin sp. nov. and Metabemisia palawana Martin sp. nov. are described from fern hosts in Sulawesi, Borneo and Palawan, respectively. An annotated check list of whiteflies feeding on pteridophyte hosts worldwide is presented, including host records and geographical distribution. A table is presented, comparing the names of fern hosts from literature with their current status.

The Relationship

The Dingo Debate explores the intriguing and relatively unknown story of Australia’s most controversial animal – the dingo. Throughout its existence, the dingo has been shaped by its interactions with human societies. With this as a central theme, the book traces the story of the dingo from its beginnings as a semi-domesticated wild dog in South-east Asia, to its current status as a wild Australian native animal under threat of extinction. It describes how dingoes made their way to Australia, their subsequent relationship with Indigenous Australians, their successful adaption to the Australian landscape and their constant battle against the agricultural industry. During these events, the dingo has demonstrated an unparalleled intelligence and adaptable nature seen in few species. The book concludes with a discussion of what the future of the dingo in Australia might look like, what we can learn from our past relationship with dingoes and how this can help to allow a peaceful co-existence. The Dingo Debate reveals the real dingo beneath the popular stereotypes, providing an account of the dingo’s behaviour, ecology, impacts and management according to scientific and scholarly evidence rather than hearsay. This book will appeal to anyone with an interest in Australian natural history, wild canids, and the relationship between humans and carnivores.

To determine the immunization status of pediatric patients under age of 5 years visiting pediatric department of tertiary care hospitals in South East Asia. The aim of this study was to appreciate the awareness and implementation of vaccination in pediatric patients who came into pediatric outpatient Department with presenting complain other than routine vaccination. we can also know the count of patients who do not complete their vaccination after birth. we can differentiate between vaccinated and unvaccinated patients and incidence of severe disease in both groups. Immunization is a protective process which makes a person resistant to the harmful diseases prevailing in the community, typically by vaccine administration either orally or intravenously. It is proven for controlling and eliminating many threatening diseases from the community. WHO report that licensed vaccines are available for the prevention of many infectious diseases. After the implementation of effective immunization the rate of many infectious diseases have declined in many countries of the world. South-East Asia is far behind in the immunization coverage. An estimated total coverage is 56%-88% for a fully immunized child, which is variable between countries. Also the coverage is highest for BCG and lowest for Polio.

It had long been believed that none of the bird, egg or nest specimens that had been in the collection of Sir Hans Sloane at his death in 1753 had survived. However, a specimen of a rhinoceros hornbill, originally in Sloane's hands, was discovered in the Natural History Museum's collections in London in 2003, and three more Sloane hornbill specimens have subsequently come to light. In addition, we report here a most unexpected discovery, that of the head of a woodpecker among the pages of one of Sloane's bound volumes of pressed plants. The context suggests that the head, like its associated plant specimens, was probably collected in south-east Asia about 1698–1699 by Nathanael Maidstone, an East India Company trader, the material reaching Sloane via William Courten after the latter's death in 1702. A detailed description of the head is provided, along with observations on its identity and possible provenance.
