Resumen

La preocupació pels greus problemes ambientals i econòmics causats per les invasions biològiques ha provocat un enorme interès en tractar de comprendre els factors que influeixen en el procés invasiu. Aquesta informació és essencial per prevenir, avaluar i mitigar els impactes de les espècies invasores. En aquest context, aquesta tesi té dos objectius principals. El primer és descobrir què fa que una espècie tingui èxit en la invasió, i el segon investigar si aquests descobriments poden ser útils per prevenir els impactes dels invasors. Aquesta tesi explora aquestes qüestions utilitzant les au

Resumen

This research paper is written in a first-person narrative style. The style mirrors the practice-led research methodology I have used which privileges process over resolution and acknowledges that making can be both generative and interrogative. More traditional research methods rely on distancing the researcher from production and placing them within an external framework. Practice-led researchers “construct experiential starting points from which practice follows. They tend to ‘dive in’, to commence practising to see what emerges. They acknowledge that what emerges is individualistic and idi

Resumen

Uric acid is a nitrogenous compound that is produced as an end product of the deamination of amino acids. Many insects and all reptiles and birds excrete the majority of excess nitrogen as solid uric acid granules that are suspended in the urine. However, the solid uric acid is not in crystalline form, but is packaged into small, spherical structures that are usually 3 - 15 μm in diameter. Further, the uric acid that is dissolved in the urine exceeds its aqueous solubility limit and the solubility limits of the potassium and sodium urate salts. Thus, a factor(s) in the urine is facilitating ur

Resumen

Most emerging diseases are of zoonotic origin. Globalization and intensive animal farming has led to an increased spread of zoonotic infections and it is therefore of crucial importance to be prepared in managing potential outbreaks. Influenza type A virus is cause of a zoonotic disease, which can affect animal and human health. A number of influenza virus subtypes have successfully crossed the species barrier and have established in mammal and human populations, causing yearly seasonal epidemics. The influenza A viruses of the H9N2 subtype are classified as low pathogenic avian influenza (AI)

Resumen

Several species of Neotropical migrant songbirds are experiencing declining population numbers. One of many proposed reasons for these declines is the dramatic loss of suitable prairie and grassland nesting habitat in the central United States. The Konza Prairie - a native tallgrass prairie preserve in central Kansas - was used to study possible edge-effect predation of artificial avian ground nests. Two Japanese quail eggs were placed in created artificial nests along transect lines from a wooded edge, a recently burned edge, and a control area. The rate of nest predation after seven days was

Resumen

Avian researchers and the poultry industry have experienced a massive loss of genetic resources due to the high cost of maintaining live flocks. Cryobanking of germplasm is economical and ensures long-term availability of genetic resources. Cryopreservation and transplantation of avian gonadal tissue allow effective preservation and recovery of female germplasm and provide an alternative to semen cryobanking. A vitrification protocol including dimethyl sulphoxide, ethylene glycol and sucrose as cryoprotective agents and the use of acupuncture needles to facilitate tissue handling has been s

A 4.0 Kb (2.64 Mdal) plasmid was isolated from a fowl cholera strain of Pasteurella multocida (the Larsen strain) by alkaline lysis and cesium chloride purification. The plasmid, designated pLAR-1, was characterized in terms of its size and restriction sites. The restriction patterns produced by fourteen endonucleases were used to generate a restriction map. Five restriction enzymes cleaved the plasmid at multiple sites. Two enzymes, Bgl II and Sal I had unique sites on pLAR-1. Twelve of the fifty six strains of P. multocida surveyed contained plasmids of different sizes which hybridized to p

Resumen

Avian leukosis virus (ALV)-induced osteopetrosis is a proliferative disorder of the bone affecting the growth and differentiation of osteoblasts. Osteopetrosis is a polyclonal disease in which cells of the bone contain, on average, multiple viral DNA copies. Osteopetrotic bone is also characterized by the accumulation of unintegrated viral DNA, suggesting an atypical life cycle of the virus in the infected osteoblasts. To better understand virus-host interactions in the induction of osteopetrosis by ALVs, infected chick osteoblast cultures and osteopetrotic bone were examined for aspects of th

Resumen

The ecological importance of introduced mammalian predators is well acknowledged in New Zealand, however, little research has focused on the ecology of native avian predators and their role in communities. This study investigated the ecology of moreporks (Ninox novaeseelandiae) on Ponui Island, Hauraki Gulf, New Zealand between August 2007 and April 2008. The primary aim was to investigate the functional response of moreporks to availability of their prey. The contents of regurgitated morepork pellets were compared with relative abundance of prey taxa (invertebrates, small birds and rodents) o

Resumen

In 1997, the first human case of avian influenza infection was reported in Hong Kong. Since then, avian influenza has become more and more hazardous for both animal and human health. Scientists believed that it would not take long until the virus mutates to become contagious from human to human. In this thesis, we construct avian influenza with possible mutation situations in bird-human systems. Also, possible control measures for humans are introduced in the systems. We compare the analytical and numerical results and try to find the most efficient control measures to prevent the disease.

Resumen

This thesis addresses issues related to surveillance for disease in commercial and non-commercial poultry populations. The motivation for this work has largely arisen from the unprecedented outbreaks of highly pathogenic avian influenza (HPAI) H5N1 that have occurred in 52 countries in Asia, Africa and Europe since 2003. A series of studies are presented using data derived from two countries, Vietnam and New Zealand. The two Vietnamese studies provide in-depth epidemiological analyses of the outbreak of HPAI H5N1 from December 2003 to March 2004. The three New Zealand studies deal with issues

Eight studies of the epidemiological dynamics of avian influenza viruses were conducted on poultry in Hong Kong, with special focus on the movement of birds through the live poultry marketing system, and the implications for avian influenza transmission. The first involved analysis of virus isolation data from faecal samples obtained from cooperating stalls in live poultry markets in Hong Kong in a routine sampling program undertaken between 1999 and 2001. This showed that two subtypes of avian influenza viruses, H9N2 and H6N1, have become well established in the Hong Kong live poultry markets

Microbial infection of eggs was originally investigated in terms of human health only. Recently, however, it was found that it can also cause early embryo mortality in birds, mainly through trans-shell infection prior to incubation. Trans-shell infection is highly dependent upon environmental conditions, egg temperature and egg properties such as shell quality and antimicrobial defences. Microbial infection of eggs is more likely to occur in synchronously incubating species as first laid eggs can be exposed for up to several days prior to full incubation.

Translocation of threatened reptile species to pest-free offshore islands is one of the most important conservation management tools available in New Zealand. However, a limited knowledge of how an animal responds to translocation and what factors threaten their survival prevails. Post-translocation monitoring is crucial and may help explain the reasons for translocation failure, but only if monitoring techniques are effective in detecting animals postrelease.
