- Widespread horizontal genomic exchange does not erode species barriers among sympatric ducksRobert H S Kraus
Resource Ecology Group, Wageningen University, 6700 AA Wageningen, The Netherlands
BMC Evol Biol 12:45. 2012..There are many sympatric and ecologically similar duck species, among which fertile hybrids occur relatively frequently in nature, yet these species remain distinct...
- Evolution and connectivity in the world-wide migration system of the mallard: inferences from mitochondrial DNARobert H S Kraus
Resource Ecology Group, Wageningen University, 6700 AA, Wageningen, The Netherlands
BMC Genet 12:99. 2011..Hypothesised mallard flyways are tested explicitly by analysing mitochondrial mallard DNA from the whole northern hemisphere...
- Western sandpipers have altered migration tactics as peregrine falcon populations have recoveredRonald C Ydenberg
Centre for Wildlife Ecology and Behavioural Ecology Research Group, Simon Fraser University, Burnaby, British Columbia V5A 1S6, Canada
Proc Biol Sci 271:1263-9. 2004..Such behavioural changes are probably general among migratory shorebird species, and may be contributing to the widespread census declines reported in North America...
- Interannual differences in the relative timing of southward migration of male and female western sandpipers (Calidris mauri)Ronald C Ydenberg
Centre for Wildlife Ecology, Department of Biological Sciences, Simon Fraser University, Burnaby, BC, Canada
Naturwissenschaften 92:332-5. 2005..14 days). There was wide variation among years, however, and males actually preceded females in years with late hatch. We relate these findings to hypotheses for female-first southward migration in sandpipers...
- Winter body mass and over-ocean flocking as components of danger management by Pacific dunlinsRonald C Ydenberg
Centre for Wildlife Ecology, Simon Fraser University, Burnaby, BC V5A 1S6, Canada
BMC Ecol 10:1. 2010..We therefore predicted an increase in the frequency of over-ocean flocking as well as a decrease in the amount of fat carried by dunlins over these decades...
