Article
S. Hooson, Auteur ; I. G. Jamieson, AuteurThis paper reviews and updates the distribution and status of two geographically distinct subspecies of New Zealand Saddleback Philesturnus carunculatus, a New Zealand forest passerine that is highly susceptible to predation by introduced mammal[...]
Article
K. L. White, Auteur ; D. K. Eason, Auteur ; I. G. Jamieson, Auteur ; B. C. Robertson, AuteurDecreased genome-wide heterozygosity of inbred individuals can result in reduced survival and reproductive fitness (i.e. inbreeding depression). However, showing such heterozygosity-fitness correlations in endangered species, especially those th[...]
Article
I. G. Jamieson, AuteurThe relative importance of genetic factors in increasing the risk of extinction has been hotly debated in the past and has tended to be downplayed by ecologists researching the correlates of extinction of island endemics. More recently, Frankham[...]
Article
I. G. Jamieson, Auteur ; G. C. Wilson, AuteurTranslocations of threatened species play an increasingly important role in conservation management. However, few studies have examined what effects, if any, the translocation process itself (i.e. catching, handling, confining, transferring and [...]
Article
I. G. Jamieson, Auteur ; L. N. Tracy, Auteur ; D. Fletcher, Auteur ; D. P. Armstrong, AuteurReintroductions of threatened species are increasingly common in conservation. The translocation of a small subset of individuals from a genetically diverse source population could potentially lead to substantial inbreeding depression due to the[...]

Article
L. N. Tracy, Auteur ; G. P. Wallis, Auteur ; M. G. Efford, Auteur ; I. G. Jamieson, AuteurReintroduction guidelines recommend that 'adequate' numbers of individuals be released to minimize loss of genetic diversity, but these numbers are rarely quantified. We present a framework for assessing the number of individuals required for an[...]
Article
S. S. Taylor, Auteur ; I. G. Jamieson, Auteur ; D. P. Armstrong, AuteurPopulations established with a small number of founders are thought to have a high risk of extinction due to Allee effects, demographic stoebasticity, inbreeding and reduced genetic variation. We tested whether the initial number of birds releas[...]
Article
R. E. Simmons, Auteur ; P. Barnard, Auteur ; I. G. Jamieson, AuteurThe ability of wetland birds to rapidly find and exploit ephemeral pans is well known in arid lands, but the episodic nature of such events means that the methods employed are poorly understood. Birds may: (i) wander randomly until wetlands are [...]
