In this project, we will test how male Zebra Finches conform to their individualised social niche as set by the prevailing level of sexual competition. We will first quantify male niche conformance by analysing adjustment of sexual competitiveness including behavioural (e.g. aggression) and ejaculate (e.g. sperm motility) traits. We will then identify the underlying mechanisms on the endocrinological (via hormone profiling) and transcriptomic (via RNAseq) levels. Next, we will assess the adaptive significance of niche conformance using a niche match/mismatch approach. Finally, we will test for trade-offs between investment in sexual competitiveness versus paternal care.

在这个项目中，我们将测试雄性斑胸草雀如何符合他们的个性化的社会利基设置的普遍水平的性竞争。我们将首先通过分析性竞争力的调整，包括行为（如侵略）和射精（如精子活力）性状来量化男性生态位的一致性。然后，我们将在内分泌（通过激素分析）和转录组（通过RNAseq）水平上确定潜在的机制。接下来，我们将使用小生境匹配/失配方法评估小生境一致性的适应意义。最后，我们将测试性竞争力投资与父亲照顾之间的权衡。
