- 摘要：
- inbreeding depression (i.e., genetic effects of elevated homozygosity) or from post-mating maternal investment. This can be due to a reduction in female investment after
Data from: Perceived threats of infanticide reduce maternal allocation during lactation and lead to elevated oxidative damage in offspring

- 摘要：
- Maternal investment is costly to the mother but essential to offspring survival in altrical species. Infanticide by novel males results in loss
