The use of a robust capture-recapture design in small mammal population studies: A field example with Microtus pennsylvanicus The use of a robust capture-recapture design in small mammal population studies: A field example with Microtus pennsylvanicus
The robust design of Pollock (1982) was used to estimate parameters of a Maryland M. pennsylvanicus population. Closed model tests provided strong evidence of heterogeneity of capture probability, and model M eta (Otis et al., 1978) was selected as the most appropriate model for estimating population size. The Jolly-Seber model goodness-of-fit test indicated rejection of the model for...

Testing for variation in taxonomic extinction probabilities: A suggested methodology and some results Testing for variation in taxonomic extinction probabilities: A suggested methodology and some results
Several important questions in evolutionary biology and paleobiology involve sources of variation in extinction rates. In all cases of which we are aware, extinction rates have been estimated from data in which the probability that an observation (e.g., a fossil taxon) will occur is related both to extinction rates and to what we term encounter probabilities. Any statistical method for...

Observer visitation frequency and success of mourning dove nests: A field experiment Observer visitation frequency and success of mourning dove nests: A field experiment
Field studies of nesting success generally require visits by the investigator to the nests under study. Such visits may themselves influence nesting success, however, and this possibility has been discussed and investigated by a number of workers with a variety of bird species. Livezey (1980) reviewed the relevant literature for duck nests and noted that most studies failed to...
