This data set includes information on collections of fecal samples from wild gulls (Larus spp.) at seven locations in Alaska, USA. Samples were screened for Escherichia coli (E. coli) and tested for resistance to multiple antibiotics.
Genetic Data for Merlin (Falco columbarius) and Cross-Species Microsatellite Amplification in Select Falco Species, North America Genetic Data for Merlin (Falco columbarius) and Cross-Species Microsatellite Amplification in Select Falco Species, North America
This data set contains allele sizes for 8 previously published and 16 novel microsatellite loci, and one microsatellite redesigned for amplification in Merlins (Falco columarius) associated with circadian clock control and polymorphism that has been associated with juvenile dispersal and migratory behavior in some avian species for Merlin (Falco columbarius) from North America (n=21)...
