nuclear locus divergence at the early stages of speciation in the orchard oriole complex.as two lineages diverge from one another, mitochondrial dna should evolve fixed differences more rapidly than nuclear dna due to its smaller effective population size and faster mutation rate. as a consequence, molecular systematists have focused on the criteria of reciprocal monophyly in mitochondrial dna for delimiting species boundaries. however, mitochondrial gene trees do not necessarily reflect the evolutionary history of the taxa in question, and even mitochondrial loci are not expected t ...201627386077
blood parasites of nearctic-neotropical migrant passerine birds during spring trans-gulf migration: impact on host body condition.to test the hypothesis that migrants infected with blood parasites arrive on the northern coast of the gulf of mexico in poorer condition than uninfected birds, we examined 1705 migrant passerine birds representing 54 species of 11 families from 2 gulf coast sites for blood parasites. three hundred and sixty (21.1%) were infected with 1 or more species of 4 genera of blood parasites. the prevalence of parasites was as follows: haemoproteus spp. (11.7%), plasmodium spp. (6.7%), leucocytozoon spp. ...200617152939
avian and mammalian hosts for spirochete-infected ticks and insects in a lyme disease focus in connecticut.spirochetes and their vectors and reservoirs were studied in a lyme disease focus in east haddam, connecticut, from mid-may through september 1983. ixodes dammini subadults were comparable in number on white-footed mice (peromyscus leucopus) (means = 2.9 +/- 3.6 sd) to those on 27 different species of birds (means = 2.3 +/- 4.2 sd) representing 11 families within the order passeriformes. less commonly found ticks on birds (means less than or equal to 0.1) were immature ixodes dentatus and haemap ...19846516460
