Data from: Trophic sensitivity of invasive predator and native prey interactions: integrating environmental context and climate change

Brian S. Cheng, Lisa M. Komoroske & Edwin D. Grosholz
Climate change is predicted to intensify the impacts of invasive species by enhancing their performance relative to their native counterparts. However, few studies have compared the performance of invasive predators and native prey, despite the fact that non-native predators are well known to disrupt native communities. The ‘trophic sensitivity hypothesis’ suggests that predators are less tolerant of increasing environmental stress than their prey, whereas the ‘tolerant invaders hypothesis’ suggests that invaders are more tolerant than...

Data from: Post-glacial habitat release and incipient speciation in the genus Delphinus

Iris Segura-García, Juan Pablo Gallo, Susan Chivers, Raúl Díaz-Gamboa & A. Rus Hoelzel
The role of ecological and changing environmental factors in the radiation of species diversity is a fundamental question in evolutionary biology. Of particular interest is the potential for these factors to determine the boundary between what we would consider differentiation among populations and incipient speciation. Dolphins in the genus Delphinus provide a useful test case, exhibiting morphological variation in beak length, coloration and body size across their wide geographic distribution, and in particular among coastal...

Data from: Genetic variation in blue whales in the eastern Pacific: implication for taxonomy and use of common wintering grounds

Richard G. LeDuc, F.I. Archer, Aimee R. Lang, Karen K. Martien, Brittany Hancock-Hanser, Juan P. Torres-Florez, Rodrigo Hucke-Gaete, Howard C. Rosenbaum, Koen Van Waerebeek, Robert L. Brownell, Barbara L. Taylor & F. I. Archer
Many aspects of blue whale biology are poorly understood. Some of the gaps in our knowledge, such as those regarding their basic taxonomy and seasonal movements, directly affect our ability to monitor and manage blue whale populations. As a step towards filling in some of these gaps, microsatellite and mtDNA sequence analyses were conducted on blue whale samples from the Southern Hemisphere, the eastern tropical Pacific (ETP), and the northeast Pacific. The results indicate that...

Data from: What influences the worldwide genetic structure of sperm whales (Physeter macrocephalus)?

Alana Alexander, Debbie Steel, Kendra Hoekzema, Sarah L. Mesnick, Daniel Engelhaupt, Iain Kerr, Roger Payne & Charles Scott Baker
The interplay of natural selection and genetic drift, influenced by geographic isolation, mating systems and population size, determines patterns of genetic diversity within species. The sperm whale provides an interesting example of a long-lived species with few geographic barriers to dispersal. Worldwide mtDNA diversity is relatively low, but highly structured among geographic regions and social groups, attributed to female philopatry. However, it is unclear whether this female philopatry is due to geographic regions or social...

Data from: Staying close to home? Genetic differentiation of rough-toothed dolphins near oceanic islands in the central Pacific Ocean

G. Renee Albertson, Robin W. Baird, Marc Oremus, M. Michael Poole, Karen K. Martien & C. Scott Baker
Rough-toothed dolphins have a worldwide tropical and subtropical distribution, yet little is known about the population structure and social organization of this typically open-ocean species. Although it has been assumed that pelagic dolphins range widely due to the lack of apparent barriers and unpredictable prey distribution, recent evidence suggests rough-toothed dolphins exhibit fidelity to some oceanic islands. Using the most comprehensively extensive dataset for this species to date, we assess the isolation and interchange of...
