Mark–recapture estimates of daily survival rates of two damselflies (Coenagrion puella and Ischnura elegans)
Male-biased operational sex ratios are very common in sexually mature dragonflies. These may be due to differential survival or differences in time spent at the breeding site by the sexes. Because most studies are carried out at the breeding site, these two processes can be measured as survival rates or recapture rates using modern capture– mark–recapture methods. We marked 66 female and 233 ma...
متن کاملMark-recapture estimates of stickleback population sizes
Previous knowledge of population sizes of fish in these lakes comes from a mark-recapture study carried out in Paxton Lake in May, 2005 (M. Nomura and D. Schluter, unpublished). The results of this effort are shown in Table S1 of the Supplement. These estimates are now stale, being more than 10 years out of date. The estimates were based on relatively small samples, leading to highly uncertain ...
متن کاملThe Influence of Mark-Recapture Sampling Effort on Estimates of Rock Lobster Survival.
Five annual capture-mark-recapture surveys on Jasus edwardsii were used to evaluate the effect of sample size and fishing effort on the precision of estimated survival probability. Datasets of different numbers of individual lobsters (ranging from 200 to 1,000 lobsters) were created by random subsampling from each annual survey. This process of random subsampling was also used to create 12 data...
متن کاملSimultaneous Use of Mark-recapture and Radiotelemetry to Estimate Survival, Movement, and Capture Rates
Biologists often estimate separate survival and movement rites from radiotelemetry and markrecapture data from the same study population. We describe a method for combining these data types in a single model to obtain joint, potentially less biased estimates of survival and movement that use all available data. We furnish an example using wood thrushes (Hylocichla mustelina) captured at the Pie...
متن کاملA new approach to the "apparent survival" problem: estimating true survival rates from mark-recapture studies.
Survival estimates generated from live capture-mark-recapture studies may be negatively biased due to the permanent emigration of marked individuals from the study area. In the absence of a robust analytical solution, researchers typically sidestep this problem by simply reporting estimates using the term "apparent survival." Here, we present a hierarchical Bayesian multistate model designed to...
