In contrast, all three lice species showed similar shifts in the enrichments in carbon and nitrogen signatures relative to those from host feathers, indicating their preferences on feathers remains and other debris.
Similarly, there were significant differences between values of host blood and all other tissue types (All P<0.001), however significance did not hold in the case of host feathers which showed similar carbon values to lice except for the louse S. peusi (D = 0.136, P<0.001).
Host feathers were washed in a 0.25 M sodium hydroxide solution, rinsed thoroughly in distilled water to remove any surface contamination, dried in an oven at 60°C to constant mass, and then grounded to powder using a SPEX 6750 Freezer/Mill.
This Won't Be Pretty Long - a newly bleached dead coral hosts feather worms that will probably be smothered as brown algae covers the surface.
The common tern hosts feather lice, which are quite different from those found in Arctic terns, despite the close relationship of the two birds.
On the other hand, Ischnocera lice feed on the keratin of feathers, thus indirectly affecting their host through feather damage.
This swift is host to feather mites including Eustathia cultrifera, Chauliacia canarisi and C. securigera.
In 2013, trendy quarterly magazine Dumbo Feather hosted An Evening With Paul Jennings.
Overall, δ15N signatures of all four ectoparasites were greater than those of the host blood or feathers (All P<0.001).
We analyzed the carbon and nitrogen stable isotope signatures of host blood and feathers as well as of whole individuals for each ectoparasite species to investigate geographic variation and trophic relationships of ectoparasites in relation to their hosts.
Discrimination factors of carbon and nitrogen were calculated as the difference between the isotopic ratios (δ15N or δ13C) in each ectoparasite species and the host tissue (blood or feather).
