Data from: Detecting signals of chronic shedding to explain pathogen persistence: Leptospira interrogans in California sea lionsMichael G. Buhnerkempe, Katherine C. Prager, Christopher C. Strelioff, Denise J. Greig, Jeff L. Laake, Sharon R. Melin, Robert L. DeLong, Frances M. D. Gulland & James O. Lloyd-Smith
Identifying mechanisms driving pathogen persistence is a vital component of wildlife disease ecology and control. Asymptomatic, chronically infected individuals are an oft-cited potential reservoir of infection but demonstrations of the importance of chronic shedding to pathogen persistence at the population level remain scarce. Studying chronic shedding using commonly collected disease data is hampered by numerous challenges, including short-term surveillance that focuses on single epidemics and acutely ill individuals, the subtle dynamical influence of chronic shedding...
The complex processes involved with animal migration have long been a subject of biological interest and broad-scale movement patterns of many marine turtle populations still remain unresolved. While it is widely accepted that once marine turtles reach sexual maturity they home to natal areas for nesting or reproduction, the role of philopatry to natal areas during other life stages has received less scrutiny, despite widespread evidence across the taxa. Here we report on genetic research...
Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits...
Data from: Human-mediated evolution in a threatened species? Juvenile life-history changes in Snake River salmonRobin S. Waples, Anna Elz, Billy D. Arnsberg, James R. Faulkner, Jeffrey J. Hard, Emma Timmins-Schiffman & Linda K. Park
Evaluations of human impacts on Earth's ecosystems often ignore evolutionary changes in response to altered selective regimes. Freshwater habitats for Snake River fall Chinook salmon (SRFCS), a threatened species in the U.S., have been dramatically changed by hydropower development and other watershed modifications. Associated biological changes include a shift in juvenile life history: historically essentially 100% of juveniles migrated to sea as subyearlings, but a substantial fraction have migrated as yearlings in recent years. In...
Data from: Satellite telemetry reveals higher fishing mortality rates than previously estimated, suggesting overfishing of an apex marine predatorMichael E. Byrne, Enric Cortés, Jeremy J. Vaudo, Guy C. McN. Harvey, Mark Sampson, Bradley M. Wetherbee & Mahmood Shivji
Overfishing is a primary cause of population declines for many shark species of conservation concern. However, means of obtaining information on fishery interactions and mortality, necessary for the development of successful conservation strategies, are often fisheries-dependent and of questionable quality for many species of commercially exploited pelagic sharks. We used satellite telemetry as a fisheries-independent tool to document fisheries interactions, and quantify fishing mortality of the highly migratory shortfin mako shark (Isurus oxyrinchus) in the...
Data from: Linking social and spatial networks to viral community phylogenetics reveals subtype-specific transmission dynamics in African lionsNicholas M. Fountain-Jones, Craig Packer, Jennifer L. Troyer, Kimberly VanderWaal, Stacie Robinson, Maude Jacquot & Meggan E. Craft
1.Heterogeneity within pathogen species can have important consequences for how pathogens transmit across landscapes; however, discerning different transmission routes is challenging. 2.Here we apply both phylodynamic and phylogenetic community ecology techniques to examine the consequences of pathogen heterogeneity on transmission by assessing subtype specific transmission pathways in a social carnivore. 3.We use comprehensive social and spatial network data to examine transmission pathways for three subtypes of feline immunodeficiency virus (FIVPle) in African lions (Panthera leo)...
