Data from: A high-resolution panorama camera system for monitoring colony-wide seabird nesting behaviour

Tim P. Lynch, Racheal Alderman, Alistair J. Hobday & Rachael Alderman
1. Obtaining accurate and representative demographic metrics for animal populations is critical to many aspects of wildlife monitoring and management. However, at remote animal colonies, metrics derived from sequential counts or other continuous monitoring are often subject to logistical, weather and disturbance challenges.The development of remote camera technologies has assisted monitoring, but limitations in spatial and temporal resolution and sample sizes remain. 2. Here we describe the application of a robotic camera system (Gigapan) which...

Data from: Cultural traditions across a migratory network shape the genetic structure of southern right whales around Australia and New Zealand

E. L. Carroll, C. S. Baker, M. Watson, R. Alderman, J. Bannister, O. E. Gaggiotti, D. R. Gröcke, N. Patenaude & R. Harcourt
Fidelity to migratory destinations is an important driver of connectivity in marine and avian species. Here we assess the role of maternally directed learning of migratory habitats, or migratory culture, on the population structure of the endangered Australian and New Zealand southern right whale. Using DNA profiles, comprising mitochondrial DNA (mtDNA) haplotypes (500 bp), microsatellite genotypes (17 loci) and sex from 128 individually-identified whales, we find significant differentiation among winter calving grounds based on both...

Data from: Chemical suppression of embryonic cane toads Rhinella marina by larval conspecifics

Gregory S. Clarke, Michael R. Crossland, Cathy Shilton & Richard Shine
1. Mechanisms that evolved to suppress the development of potential competitors may offer novel methods for species-specific control of invasive organisms. The tadpoles of cane toads Rhinella marina compete for limited food resources in small ponds, and older tadpoles eliminate competitors not only by eating newly-laid eggs, but also by releasing a chemical that suppresses development of conspecific eggs. 2. We conducted laboratory trials to assess the magnitude and generality of this suppression effect, and...

Data from: Evolutionary factors affecting the cross-species utility of newly developed microsatellite markers in seabirds

Yoshan Moodley, Juan F. Masello, Gopi K. Munimanda, Theresa L. Cole, Marco R. Thali, Rachael Alderman, Richard J. Cuthbert, Manuel Marin, Melanie Massaro, Joan Navarro, Richard A. Phillips, Peter G. Ryan, Cristián G. Suazo, Yves Cherel, Henri Weimerskirch, Petra Quillfeldt & Luciano Calderon
Microsatellite loci are ideal for testing hypotheses relating to genetic segregation at fine spatio-temporal scales. They are also conserved among closely related species, making them potentially useful for clarifying interspecific relationships between recently diverged taxa. However, mutations at primer binding sites may lead to increased nonamplification, or disruptions that may result in decreased polymorphism in nontarget species. Furthermore, high mutation rates and constraints on allele size may also with evolutionary time, promote an increase in...
