Název v původním jazyce

Sperm variation in great tit males (Parus major) is linked to a haematological health-related trait, but not ornamentation

Popis výsledku v původním jazyce

The phenotype-linked fertility hypothesis (PLFH) proposes that both sexual ornaments and sperm traits are phenotypically plastic and co-affected by environmental factors through individual condition, resulting in a positive correlation between ornament expression and functional fertility. Ornaments may then serve females in the identification of the most fertile males. Despite intense research on the relationship between sexual characters and male ejaculate quality, published results are not consistent with the PLFH. The aim of our study was to test if sperm morphology is associated with sexual ornamentation and several health/condition-dependent traits in great tit males (Parus major). We evaluated the association between sperm morphology and two types of ornaments, carotenoid- and melanin-based ventral feather coloration, to evaluate predictions of the PLFH. As surrogates for condition and health/stress status, we used standardized male weight and the peripheral blood heterophil to lymphocyte rati
