New research reports the foraging association between the piscivorous Japanese #amberjack (Seriola quinqueradiata) and the zoobenthivorous Asian sheephead #wrasse (Semicossyphus reticulatus): doi.org/10.1111/jfb.70140 #JFB
Our Hawaiian Word for today is a beautiful Oʻahu place name, Kaʻaʻawa. It is often used as an example of a Hawaiian word with so many vowels in a row. But if you spell and pronounce it correctly, you will note that every vowel is separated by a consonant sound, the glottal stop or ʻokina. And it means the wrasse fish.
Female ocellated wrasse perform cryptic mate selection by controlling sperm velocity, performing sexual selection after mating. However, warmer waters reduce the females' ability to control sperm velocity, reducing their ability to enforce mate preference.

Reproduction is often more thermally sensitive than survival. Thus, understanding the thermal sensitivity of reproductive interactions is crucial given global warming. However, it is unknown how temperature influences female control over fertilization after mating (i.e., cryptic female choice). We tested how temperatures relevant to current conditions and climate change projections influence cryptic female choice in a marine fish, Symphodus ocellatus. Under typical conditions, females bias fertilization dynamics to favor dominant males. We find that warmer temperatures decrease female influence on sperm velocity and reduce the expected paternity of dominant males. Our results demonstrate that temperatures relevant to climate change can shift the balance between mate choice and male-male competition. Thus, climate change may influence sexual selection, leading to evolutionary changes in reproductive traits. ### Competing Interest Statement The authors have declared no competing interest.
