Comparative Demography of New World Populations of Thrushes (turdus Ssp.): Reply
Conn, Doherty, and Nichols (2005), hereafter CD&N, question the wisdom of using age ratios obtained from museum collections to estimate adult survival rates in populations of birds. Ricklefs (1997), Rohwer (2004), and other studies that have used this approach have been careful to recognize and evaluate potential problems, to the extent possible. The basic assumptions of the method are that adu...

متن کاملLong-Term Effects of Chronic Light Pollution on Seasonal Functions of European Blackbirds (Turdus merula)
Light pollution is known to affect important biological functions of wild animals, including daily and annual cycles. However, knowledge about long-term effects of chronic exposure to artificial light at night is still very limited. Here we present data on reproductive physiology, molt and locomotor activity during two-year cycles of European blackbirds (Turdus merula) exposed to either dark ni...
متن کاملMolecular systematics of a speciose, cosmopolitan songbird genus: defining the limits of, and relationships among, the Turdus thrushes.
The avian genus Turdus is one of the most speciose and widespread of passerine genera. We investigated phylogenetic relationships within this genus using mitochondrial DNA sequence data from the ND3, ND2 and cytochrome b genes. Our sampling of Turdus included 60 of the 65 extant species currently recognized, as well as all four species from three genera previously shown to fall inside Turdus (P...
