| [clutch size, nesting success and breeding success rate in emberiza jankowskii in the grassland at baicheng in jilin province]. | in this article, clutch size, nesting success and breeding success rate of emberiza jankowskii living in grassland habitats in baicheng region of jilin province were studied from may to july in 1999. the results showed average clutch size was 5.09 +/- 0.58 eggs per nest. there was negative correlation between clutch size and initial laying date, brood quantity and initial laying date, clutch size and fresh egg weight. there was exceedingly negative correlation between initial laying date and inc ... | 2002 | 12132153 |
| [correlation between trace element content of eggshell and breeding characteristics of three bird species in northeast china]. | the contents of trace elements in the eggshells of emberiza jankowskii, parus major and passer montanus were examined by flame atomic absorption spectrophotometer (faas), and the correlations between these trace elements of eggshell and breeding characteristics of the three bird species were studied. in the meantime, the optimum parameters of faas were studied, and no cross effect were observed among the five trace elements. the recovery rates of standard addition of mn, mg, cu, fe and zn were 9 ... | 2009 | 19798988 |
| polymorphism in the major histocompatibility complex (mhc class ii b) genes of the rufous-backed bunting (emberiza jankowskii). | genetic diversity is one of the pillars of conservation biology research. high genetic diversity and abundant genetic variation in an organism may be suggestive of capacity to adapt to various environmental changes. the major histocompatibility complex (mhc) is known to be highly polymorphic and plays an important role in immune function. it is also considered an ideal model system to investigate genetic diversity in wildlife populations. the rufous-backed bunting (emberiza jankowskii) is an end ... | 2017 | 28149689 |
| mitochondrial genome of the emberiza jankowskii (emberizidae: emberiza). | emberiza jankowskii is an endangered species, whose population quantity decreased year by year in the limited distribution areas. the complete mitochondrial genome of e. jankowskii (16,776 bp in length) consists of 37 genes (13 protein-coding genes, 2 rrna genes, and 22 trna genes) and a non-coding region (d-loop), which is similar to the typical mtdna of vertebrates. all the protein-coding genes in e. jankowskii are distributed on the h-strand, except the nd6 subunit gene and ten trna genes, wh ... | 2016 | 25868524 |
| the composition of gut microbiota community structure of jankowski's bunting (emberiza jankowskii). | gut microbiota play a central role in the health of animals. the bacteria that individuals acquire as they age may therefore have a profound effect on their future fitness. since most birds are capable of flight, they can be widely distributed in and adapted to various ecosystems. moreover, birds are also challenged by the need to digest a wide range of food resources in their guts. however, little is known regarding how the microbial community structure in birds, especially wild birds, changes ... | 2020 | 32940730 |
