Description
Summary:[...]to obtain comprehensive insights into variation in overall rates of EPP, more studies across representative bird species from various regions are needed, especially in Asia, where few studies have been reported on this topic (Figure 6 in Brouwer & Griffith, 2019). [...]females are likely constrained by the requirement of resource investment for egg production (Cordero et al., 1999) and by greater investment in parental care (i.e., a trade-off between female parental investment and certainty of EPP, Trivers, 1972). [...]a higher level of EPP would be expected under increasing food abundance (Hoi-Leitner et al., 1999). Specifically, yellow-bellied prinias show enormous overlap between spring molting and breeding activities (both are energy-consumptive behaviors) as well as higher feeding frequencies (compared to sister species with similar body size belonging to the same family) and relatively higher annual productivity than the nine passerine bird species with similar body mass (Ding et al., 2016, 2017b). [...]the libraries were sequenced using the Illumina HiSeq2500-PE125 platform (Illumina, USA), which generates 150 bp paired-end reads.
