Contrasting the form and strength of pre-and postcopulatory sexual selection in a flatworm

L Marie-Orleach, MD Hall, L Schärer - Evolution, 2024‏ - academic.oup.com
Sexual traits may be selected during multiple consecutive episodes of selection, occurring

Genotype‐by‐environment interactions for seminal fluid expression and sperm competitive ability

B Patlar, SA Ramm - Journal of evolutionary biology, 2020‏ - academic.oup.com
