Testing life history predictions in a long-lived seabird: a population matrix approach with improved parameter estimation

Article Abstract:

Life-history predictions in a population of red-tailed tropicbirds (Phaethon rubricauda) are tested using improved methodologies. Comparative data-sets on other seabirds, within and among orders, and in other locations, are needed to understand the environmental effects (El Nino events).

Estimation by capture-recapture of recruitment and dispersal over several sites

Article Abstract:

The recruitment and dispersal in the roseate tern Sterna dugallii are analyzed. A class of age-dependent multistate capture-recapture models is presented for the simultaneous estimation of natal dispersal, breeding dispersal and age-dependent recruitment.

What does the Resource Dispersion Hypothesis explain, if anything?

Article Abstract:

The potential of Resource Dispersion Hypothesis(RDH) for explaining the sociality of Eurasian badgers is examined. The empirical evidences conflicting the assumptions and predictions of Resource Dispersion Hypothesis(RDH) are discussed.

Badgers, Eurasians
