trace metal concentration in great tit (parus major) and greenfinch (carduelis sinica) at the western mountains of beijing, china.we examined the concentrations of 11 trace metals in tissues from 10 body parts of great tits and greenfinches collected at badachu park in the western mountains of beijing, china to assess the metal accumulation level, distribution among body parts, and species and gender related variations. the highest concentrations of hg, ni, zn, and mn were found in the feather; pb and co in the bone; cd, cr, and se in the kidney, and cu in the liver and heart. metal concentrations had substantial interspec ...200717240025
structure and variation of the fringillidae (aves: passeriformes) mitochondrial dna control region and their phylogenetic relationship.the control region is the major noncoding segment of animal mitochondrial dna. to infer the structure and variation of fringillidae mitochondrial dna control region, the entire control region sequences of 25 species were analyzed. the length of the control region sequences was very conserved (1230 ± 18) and can be separated into three domains. the frequency of both substitutions and gaps was highest in the third domain and lowest in the central region. the control region has the same flanking ge ...201627549748

isospora mcquistioni and isospora bioccai (apicomplexa, eimeriidae): two new coccidian parasites from carduelis sinica (passeriformes, fringillidae).the following two species are described from carduelis sinica (greenfinch) from italy. the oocysts of isospora mcquistioni n. sp. were 26.0 x 22.6 (24.0-28.5 x 20.0-24.2) microns and ovoid with a smooth bilayered wall. neither micropyle nor oocyst residuum were observed. one polar granule was found. sporocysts were oval, 18.1 x 11.4 (16.0-19.8 x 11.0-12.0) microns, and with a symmetrical stieda complex. the residuum was compact and spherical. isospora bioccai n. sp. oocysts were spherical to sub ...20031818202
effect of tracheosyringeal denervation on call in greenfinch (carduelis sinica).after sections of left or right tracheosyringeal nerve (nxiits), greenfinches may repeat everyday calls, with no effect on temporal properties. it is suggested that either side of syrinx may produce sound alone and ipsilateral innervation of nxiits for the syringeal muscles. after section of left nxiits, the bird produces the vocal pattern of partial tone increase, and effects on the sound intensity and sentence length average 1.4 and 2.8 times those after section of right nxiits, suggesting tha ...199918726477
cryptic speciation of the oriental greenfinch chloris sinica on oceanic islands.the oriental greenfinch, chloris sinica, is a small seed-eating finch that breeds in the eastern palearctic region, an area that spans from russia in the east to china, korea, and japan in the south and southwest. several subspecies have been described based on subtle morphological characteristics, although the taxonomy varies among different authors. although many ecological studies have been performed, there has been no phylogenetic study that encompasses the species' entire geographical range ...202032549542
