We also identify persistent gaps in the field:
1 - Taxonomic bias prevails over last decades with few studies on arthropods or mammals, and none on plants
2 - Post-copulatory sexual selection still barely touched by comparative work

Does #SexualSelection fuel #Speciation?

Our new #meta-analysis of comparative studies finds support for a positive relationship, but the rather moderate global effect suggests it’s not necessarily a dominant force.

📜 Why are trade-offs often so elusive? Does the distribution of resources in a population affect if life history trade-offs emerge? We tested this experimentally in the Australian field cricket using a re-sampling approach. Now out #OpenAccess in @journal-evo.bsky.social: doi.org/10.1093/evol...

Molecular and genomic insights to sexually antagonistic genes (GRIESHOP_U26DTP) | Doctoral Training Partnership

Why do harmful genes persist in populations instead of being removed by natural selection? One answer lies in sexual antagonism: when a genetic variant benefits males but harms females, or vice versa.

How should ejaculate ejection behaviour by females be measured? And does it correlate with female pre-mating preference?
Find out in our new paper!

Ejaculate Ejection by Female Fruit Flies Does Not Correlate With Mating Latency or Male Presence, Irrespective of How Ejection Is Measured

How to measure female ejaculate ejection, is it related to pre-mating sexual selection, or influenced by post-mating sexual environment? We explore these questions in fruit flies.
