Using 2 years of mark-recapture data from the Australian gecko Nephrurus stellatus, we investigated the effect of fire on (i) detectability to reliably measure post-fire changes in abundance, and (ii) survival and reproductive rates to investigate the mechanisms of successional change.
While these studies suggest a positive outlook for bats that survive an infection with WNS, it is important to remember that the conclusions were drawn from recapture data.
Valuable information gained from recapture data includes greater understanding of species-specific migratory patterns, stock structure, spatial and temporal distribution, site fidelity/residence times, and life histories (Kohler & Turner, 2001).
The shortnose sturgeon population was estimated from mark and recapture data using the Schnabel method that assumes a closed population [26].
We used the first-order jackknife method initially designed to estimate population size from capture to recapture data, allowing capture probabilities to vary by individuals [45].
Maximum estimated longevity was determined to be 19.8 years through tag-recapture data and 18.5 years from direct age estimates for R. terraenovae and 22.8 years through tag-recapture data and 20.5 years through direct age estimates for C. acronotus.
The exact value of this probability is not easy to estimate from capture-recapture data because the detection probability is confounded by temporal emigration.
The program MARK (White and Burnham 1995) was used to simultaneously estimate recapture and survival probabilities from mark-recapture data.
Survival rates were estimated from mark-recapture data, and the effect of genotype, sex, time and season on survival was determined by model selection.
To evaluate the ecological relevance of our detection task, we compared rates of detection of black, striped and grey grasshoppers obtained in our present study with independent estimates of capture and survival probabilities of the same three colour patterns in the wild as obtained from mark-recapture data [ 29] (for details see Methods).
