Published in: Ecological Modelling Authors: Doug P. Armstrong, Elizabeth, H. Parlato & Peter G.H. Frost Abstract: Survival, reproduction and detection rates may vary greatly amongst individuals. Failure to account for this variation results in biased inferences about age effects and population size. However, individual variation is not normally considered in population viability analysis, potentially leading […]
Published in: Animal Conservation Authors: Elizabeth H. Parlato, John G. Ewen, Mhairi McCready, Fiona Gordon, Kevin A. Parker & Doug P. Armstrong Abstract: The importance of accounting for temporal variation in vital rates when modelling population dynamics is well recognized. However, long-term (usually >5Â years) datasets are needed to estimate this variation. Consequently, models for newly […]
Published in:Â Philosophical Transactions of the Royal Society of London Series B Authors: Kate M. Richardson, Elizabeth H. Parlato, Leila K. Walker, Kevin A. Parker, John G. Ewen and Doug P. Armstrong Abstract: There is growing recognition that variation in animal personality traits can influence survival and reproduction rates, and consequently may be important for wildlife […]
Published in: Conservation Science and Practice Authors: Julia Panfylova, John G Ewen and Doug Armstrong Abstract: Structured decisionâ€making (SDM) has become popular in natural resource management but has been underused in reintroduction programs. We illustrate how conservation managers can use SDM to guide management decisions after initial reintroduction, when data are still limited and uncertainty […]
Marsden Fund Success! What is the optimal level of complexity to consider when predicting population dynamics? The conventional wisdom is to keep models as simple as possible. However, the recent explosion of research on individual variation in animal personalities and life history traits is increasing our capacity to generate complex individual-based models of population dynamics. […]

Published in:Â The Journal of Wildlife Management Date published:Â May 2016 Authors:Â Julia Panfylova, Ellis Bemelmans, Chris Devine, Peter Frost, Doug Armstrong Abstract Modeling survival of reintroduced populations is critical for understanding population dynamics and therefore making appropriate management decisions. We analyzed survival data collected over the first 2 years after a reintroduction of hihi (Notiomystis cincta), an […]
