Avian influenza surveillance in Bangladesh has been passive, relying on poultry farmers to report suspected outbreaks of highly pathogenic H5N1 influenza. Here, the results of an active surveillance effort focusing on the live-bird markets are presented. Prevalence of influenza infection in the birds of the live bird markets is 23.0%, which is similar to that in poultry markets in other countri...
The trade in wild animals involves one-third of the world's bird species and thousands of other vertebrate species. Although a few species are imperiled as a result of the wildlife trade, the lack of field studies makes it difficult to gauge how serious a threat it is to biodiversity. We used data on changes in bird abundances across space and time and information from trapper interviews to eva...
Louse population fluctuates seasonally. Several factors have been held responsible for the summer buildup of population of avian lice (Marshall A.G. 1981: The Ecology of Ectoparasitic Insects. Academic Press, London, 445 pp). It has been suspected that the breeding time of two haematophagous louse species (Ricinus picturatus and Menacanthus sp.) might be controlled by the reproductive hormones ...
© 2005 FFI, Oryx, 39(4), 1–6 doi:10.1017/S0030605305001110 Printed in the United Kingdom 1 Abstract Bird-keeping is an extremely popular pastime in Indonesia, where there is a thriving internal market in both wild-caught and captive-bred birds. However, little is known about whether the scale of bird-keeping represents a genuine conservation threat to native populations. Here we present the res...
BACKGROUND Many animals reduce the risk of being attacked by a predator through crypsis, masquerade or, alternatively, by advertising unprofitability by means of aposematic signalling. Behavioural attributes in prey employed after discovery, however, signify the importance of also having an effective secondary defence if a predator uncovers, or is immune to, the prey's primary defence. In butte...
s of papers 65 refrigerated storage and after cooking compared with the nonirradiated control. Irradiated aerobically packaged meat accelerated lipid oxidation and aldehydes production at 10 d and after cooking. Gallate+tocopherol with double packaging was the most effective in reducing the red color of irradiated raw and cooked meat. Sulfur volatiles were evaporated during the aerobic period o...
