WebTo do this effectively, more advanced tools than Mayfield's ad hoc estimator are needed. The recent development of a nest-survival model in program MARK provides a powerful … WebPterosaurs died out because they weren’t as small and tended to be predators, which made it harder for them to find food once the ecosystem collapsed. There were certainly other factors, many of which aren’t understood yet. 51. [deleted] • 3 yr. ago.

WebFits user specified models to various types of capture-recapture data by creating input file and running MARK software and retrieving output WebEstimation of avian nest survival has traditionally involved simple measures of apparent nest survival or Mayfield constant-nest-survival models. However, these methods do not allow researchers to build models that rigorously assess the importance of a wide range of biological factors that affect nest survival.
