<p>Helmeted guinea fowl are social animals and only males form a hierarchy in the wild. Non-cage husbandry systems benefit the reproductive health of guinea fowl; however, there are concerns that the feeding duration of subordinate individuals is insufficient. Here, the pecking orders formed during small-scale floor feeding were investigated. There were three experimental categories: male-only (four males), female-only (four females), and mixed category (two males, two females). Each experimental category was set up three times and included different individuals. Behaviors were recorded for 130 h 52 min, 89 h 11 min, and 98 h 46 min in the male, female, and mixed categories, respectively. Male helmeted guinea fowls pecked other males, whereas females exhibited little pecking behavior. Male pecking behavior was not homogeneous within each experimental group. It has been suggested that males form a pecking order, whereas females have no hierarchy under small-scale floor-feeding conditions, as observed in the wild. In most cases, on the first day the number of pecking behaviors was low 20 min after the start of the experiment. The three subordinate individuals in the mixed category had little time to feed, whereas the other birds in the mixed category and all helmeted guinea fowl in the male- and female-only categories had longer feeding durations. We suggest that helmeted guinea fowl may be reared under small-scale floor feeding, and that the health of males should be managed. However, rearing females and males under small-scale floor feeding conditions should be avoided. This study contributes to improving the welfare of helmeted guinea fowl reared under small-scale floor feeding.</p>

<p>Ancient genome analysis has become an indispensable tool in studies of human population history and evolution since the breakthrough of whole-genome sequencing technology. The problem remains, however, that ancient genomes cannot be analyzed without crushing non-small pieces of precious specimens; moreover, in many cases, there is insufficient DNA remaining in the pieces of sample to obtain whole-genome sequences. In previous studies, therefore, a couple of indicators (e.g. racemization ratios) have been proposed to estimate the endogenous DNA in ancient samples. However, these studies have used polymerase chain reaction (PCR) to test whether endogenous DNA remains, but this has proved inadequate because the success or failure of PCR amplification does not necessarily reflect the DNA remaining. To assess the amount of endogenous DNA, we use the ratios of reads generated by next-generation sequencing (NGS) mapped to the human reference genome sequence. We investigated 40 human remains excavated from three shell-mound sites of the late to final Jomon culture. The associations between the environmental/molecular factors and the mapping ratios (MRs) were examined. There were no significant associations between the environmental factors and MRs, or between the collagen residual ratios (CRRs) and the MRs. However, we found a significant association between CRRs in rib bones and MRs. The weight of bone required to measure residual collagen is much less than that required to obtain the DNA necessary for NGS analysis, and the process of measuring CRRs is always involved in dating. Hence, we propose the collagen in the ribs as a good indicator for successful ancient genome analyses.</p>
