Love You to Death: Tale of Two Japanese Seals

The recent two cases related to seals in Japan illustrate the nature of the “values” created for animals in today’s societies: one that appeared in a river in Tokyo and gained a national pop star fame, the other supposedly extinct Japanese seal re-gaining an endangered status. This paper argues that the contrast of these cases exemplifies the images and values of nature are created, and the “wilderness” becomes over-romanticised and idealised as societies become further removed from the biosphere. This questions the meaning of the intrinsic value of nature—can it be totally free from our social needs and vested interest; is a truly bio-centric perspective possible? The paper suggests the irrelevance of the eco-centric- anthropocentric dichotomy to today’s social contexts where complex socio-cultural, economic, political issues are interwoven.

Biological, antigenic and phylogenetic characterization of the flavivirus Alfuy

Alfuy virus (ALFV) is classified as a subtype of the flavivirus Murray Valley encephalitis virus (MVEV); however, despite preliminary reports of antigenic and ecological similarities with MVEV, ALFV has not been associated with human disease. Here, it was shown that ALFV is at least 10(4)-fold less neuroinvasive than MVEV after peripheral inoculation of 3-week-old Swiss outbred mice, but ALFV demonstrates similar neurovirulence. In addition, it was shown that ALFV is partially attenuated in mice that are deficient in alpha/beta interferon responses, in contrast to MVEV which is uniformly lethal in these mice. To assess the antigenic relationship between these viruses, a panel of monoclonal antibodies was tested for the ability to bind to ALFV and MVEV in ELISA. Although the majority of monoclonal antibodies recognized both viruses, confirming their antigenic similarity, several discriminating antibodies were identified. Finally, the entire genome of the prototype strain of ALFV (MRM3929) was sequenced and phylogenetically analysed. Nucleotide (73%) and amino acid sequence (83 %) identity between ALFV and IMVEV confirmed previous reports of their close relationship. Several nucleotide and amino acid deletions and/or substitutions with putative functional significance were identified in ALFV, including the abolition of a conserved glycosylation site in the envelope protein and the deletion of the terminal dinucleotide 5'-CUOH-3' found in all other members of the genus. These findings confirm previous reports that ALFV is closely related to IMVEV, but also highlights significant antigenic, genetic and phenotypic divergence from MVEV. Accordingly, the data suggest that ALFV is a distinct species within the serogroup Japanese encephalitis virus.

Effects of artificial foods on the blood chemistry of the Australian magpie

Bird feeding on residential property is a popular activity throughout Western countries. Advocates insist the practice is beneficial, while opponents maintain that it can result in a wide range of negative outcomes including malnutrition. The biological effects of 'backyard feeding' were studied in Australian magpies Gymnorhina tibicen during the non-breeding season in 1999 in the Greater Brisbane and the Lockyer Valley regions, south-east Queensland, Australia. Six magpie populations were selected and 70 birds were individually tagged for identification. The birds were provided with processed foods, 20-40 g per bird daily. To monitor the effects of the food, blood chemistry and body mass (BM) were used as indices. Significant effects were observed in BM and plasma cholesterol (PC), showing strong sensitivity to food provisioning. Significant effects on PC and uric acid were found only when birds were fed dog sausage. Results suggest that blood PC levels in magpies are readily influenced by, probably, the lipids present in food, and that the type of food can affect blood PC levels. These effects may occur widely among fed magpies if the influence that we demonstrated at plasma level can be generalized. Following the free-ranging study, six magpies were captured and subjected to a 6-day captive experiment to determine whether the selected foods had the potential to alter the birds' blood chemistry. It was found that all of the foods, when provided ad libitum, influence at least two of the three blood parameters (PC and non-esterified fatty acids). Due to its popularity, wildlife feeding will continue. To make wildlife-feeding activities truly sustainable, there is a need for further studies. This study clearly demonstrated that the physiology of wild magpies can be affected by 'backyard feeding'.

Maximum security: 'Being in the belly of the beast'

Very little information or research is available about the operation of Maximum Security Units (MSUs) in Queensland prisons. These units were developed within existing prisons in the early 1980s to deal with the incarceration of prisoners considered to be the worst and highest risk. Drawing on a number of interviews with prison visitors and on published documents and cases, this article examines the purpose and possible shortcomings of MSUs in Queensland in light of the Standard Guidelines for Corrections in Australia (1996).
