The responses of a critically endangered mycophagous marsupial (Bettongia penicillata) to timber harvesting in a native eucalypt forest

FOREST ECOLOGY AND MANAGEMENT, 363, 190–199.

By: A. Wayne*, M. Maxwell*, C. Ward*, C. Vellios*, M. Williams* & K. Pollock n

author keywords: abundance; auditory detections; bird surveys; distance estimation; measurement error; point count surveys

TL;DR: Analysis of data from the study on black bears illustrated that estimates of survival have poor precision when relocation rates are estimated separately for live and dead animals, and it is recommended that the effort expended to relocate both living anddead animals be consistently high in each telemetry survey, so that relocation rates will be high and constant across time and mortality status.

Optimal allocation of sample sizes between regular banding and radio-tagging for estimating annual survival and emigration rates

JOURNAL OF APPLIED STATISTICS, 29(1-4), 443–457.

By: M. Nasution, C. Brownie* & K. Pollock*

TL;DR: A cost function is proposed for a study where all birds receive leg bands and a subset receives radio tags and all new releases occur at the start of the study, and it is shown that for high resighting probability, e.g. 0.6, tagging roughly 10-40% of birds with radios will give survival estimates with standard errors within the minimum range.
