Data from: Temporally and spatially partitioned behaviours of spinner dolphins: implications for resilience to human disturbanceJulian A. Tyne, David W. Johnston, Fredrik Christiansen & Lars Bejder
Selective forces shape the evolution of wildlife behavioural strategies and influence the spatial and temporal partitioning of behavioural activities to maximize individual fitness. Globally, wildlife is increasingly exposed to human activities which may affect their behavioural activities. The ability of wildlife to compensate for the effects of human activities may have implications for their resilience to disturbance. Resilience theory suggests that behavioural systems which are constrained in their repertoires are less resilient to disturbance than...
Density-dependent shifts in population processes like territoriality, reproduction, dispersal, and parasite transmission are driven by changes in contacts between individuals. Despite this, surprisingly little is known about how contacts change with density, and thus the mechanisms driving density-dependent processes. A simple linear contact-density function is often assumed, but this is not based on a sound basis of empirical data. We addressed this question using a replicated, semi-natural experiment in which we measured contacts at feeding...
Data from: Genetic isolation between coastal and fishery-impacted, offshore bottlenose dolphin (Tursiops spp.) populationsSimon J. Allen, Kate A. Bryant, Robert H. S. Kraus, Neil R. Loneragan, Anna M. Kopps, Alexander M. Brown, Livia Gerber & Michael Krützen
The identification of species and population boundaries is important in both evolutionary and conservation biology. In recent years, new population genetic and computational methods for estimating population parameters and testing hypotheses in a quantitative manner have emerged. Using a Bayesian framework and a quantitative model-testing approach, we evaluated the species status and genetic connectedness of bottlenose dolphin (Tursiops spp.) populations off remote northwestern Australia, with a focus on pelagic 'offshore' dolphins subject to incidental capture...
Data from: Native soilborne pathogens equalise differences in competitive ability between plants of contrasting nutrient-acquisition strategiesFelipe E. Albornoz, Treena I. Burgess, Hans Lambers, Hannah Etchells & Etienne Laliberté
Soilborne pathogens can contribute to the maintenance of local plant diversity by reducing differences in competitive ability between co-occurring plant species. It has been hypothesized that efficient phosphorus (P) acquisition by plants in P-impoverished ecosystems might trade off against resistance to root pathogens. This could help explain high plant diversity in severely nutrient-impoverished ecosystems. However, empirical evidence of such a trade-off remains scarce. In hyperdiverse shrublands in south-western Australia, non-mycorrhizal cluster-rooted Proteaceae are very efficient...
Data from: Current and projected global distribution of Phytophthora cinnamomi, one of the world’s worst plant pathogensTreena Burgess, John K. Scott, Keith L. McDougall, Michael J. C. Stukely, Colin Crane, William A. Dunstan, Frances Brigg, Vera Andjic, Diane White, Tim Rudman, Frans Arentz, Noboru Ota, Giles E. St.J. Hardy, Treena I. Burgess & Giles E. St. J. Hardy
Globally, Phytophthora cinnamomi is listed as one of the 100 worst invasive alien species and active management is required to reduce impact and prevent spread in both horticulture and natural ecosystems. Conversely, there are regions thought to be suitable for the pathogen where no disease is observed. We developed a CLIMEX model for the global distribution of P. cinnamomi based on the pathogen's response to temperature and moisture and by incorporating extensive empirical evidence on...
