| late pleistocene climatic changes promoted demographic expansion and population reconnection of a neotropical savanna-adapted bird, neothraupis fasciata (aves: thraupidae). | we performed phylogeographic and genetic structure analyses of neothraupis fasciata joined with species distribution modelling to evaluate whether: (1) the distribution of genetic variability shows a pattern expected by the isolation-by-distance model; (2) the influence of the pleistocene climate changes on species distribution; and (3) climate/climatic stability (hypothesis of climatic stability) as a predictor of population genetic diversity. based on two molecular datasets (nd2 and fib-5), th ... | 2019 | 30893330 |
| isolation and characterization of microsatellite loci for neothraupis fasciata, (emberizidae, passeriformes) with widely cross amplification in neotropical passerines. | we described the development and characterization of 16 microsatellite loci for the white-banded tanager (neothraupis fasciata), a neotropical passerine from cerrado (brazilian savanna). based on 24 n. fasciata from a single population, we detected moderate to high number of alleles per locus (2-18 alelles) with expected heterozygosities ranging from 0.12 to 0.92. the high combined paternity exclusion probability (0.999) and low combined genetic identity (1.72 x 10(-10)) show that the battery of ... | 2010 | 20026504 |
| raptors and "campo-cerrado" bird mixed flock led by cypsnagra hirundinacea (emberizidae:thraupinae). | bird mixed flocks including cypsnagra hirundinacea and neothraupis fasciata as species with sentinels were studied in "campo-cerrado" in order to investigate the possible relationship between alertness and the mixed flock leadership. this study was conducted from march to september 1996 and mixed flocks were observed on average for 2:30h. the time with sentinels were recorded for c. hirundinacea and n. fasciata. the sentinels of cypsnagra hirundinacea performed most of the vigilance (time with s ... | 2000 | 11188872 |
