Allozyme Frequencies in a Linear Series of Song Dialect Populations

Geographic isolation drives divergence of uncorrelated genetic and song variation in the Ruddy-capped Nightingale-Thrush ( Catharus frantzii ; Aves: Turdidae)

“…80 Vocal variation across geography (e.g. vocal dialects) can offer 81 clues in discriminating between genetically divergent populations 82 (Baker et al, 1982 fore, is thought to be driven by cultural processes analogous to 94 genetic evolution: mutation, migration, drift, and selection 95 (Lynch, 1996), but also by ecological factors like habitat structure 96 and other environmental conditions (Larom et Catchpole and Slater, 2008). 99 Neotropical humid montane forests occur between 600 and 100 3000 m elevation from southeastern Mexico to northwestern 101 Argentina, as well as the Tepuis and Atlantic Forest (Sánchez-102 .…”

Song Dialects and Gene Flow in the White-Crowned Sparrow, Zonotrichia leucophrys nuttalli

“…Analyzing the genic complements of dialect populations at Point Reyes ( Fig. 1), Baker et al (1982bBaker et al ( pp. 1027Baker et al ( -1028 concluded that "genetic differentiation [between dialect populations] is not explained by isolation-bydistance but is interpreted as a consequence of song dialects" via their negative influence on dispersal and establishment of individuals.…”

TWO DISTINCT SONG POPULATIONS OF BLUE TIT PARUS CAERULEUS IN THE FRENCH MEDITERRANEAN

“…to increase efficiency for female attraction or in male-male competition (McGregor 1991, Catchpole and Slater 1995, Lynch 1996, Martens 1996, Payne 1996. Possible selection pressures of these adaptations are: structural characteristics of vegetation that affect sound properties during transmission (Hunter and Krebs 1979, Wiley and Richard 1982, Bremond and Aubin 1990, Dabelsteen et al 1993, Aubin and Mathevon 1995; interspecific competition that may result in character shift (Lack and Southern 1949, Marler 1960, Miller 1982, Wallin 1982; social integration (Payne 1981, Rothstein andFleischer 1987); or female choice through assortative mating (Nottebohm 1969, Baker et al 1982, Searcy 1992.…”
