Thus, despite weapons and exposed sites are linked, other forces like density, costs, and female control over reproduction also shape the story.

Big thanks to my co-authors Daniel Caetano, Alexandre Palaoro and Glauco Machado for the great teamwork! (3/3)

And yes! Just as we hypothesized, male weaponry evolution is linked to reproduction in exposed breeding sites!

However, both gains and losses of weapons happened more often in exposed sites. (2/3)

Our goal? To challenge the male-biased lens in anuran bioacoustics—and move toward a more balanced understanding of communication, mating behavior, and evolution in amphibians.

We found reports of female calls in over 100 anuran species across 53 genera and 29 families. Yet most studies are anecdotal and rarely explore their function, costs, or benefits.

We summarize existing knowledge, propose a standardized classification, and highlight key challenges for future research.

For decades, scientists have focused on the loud, familiar calls of male frogs, overlooking the quieter voices of females. Our review brings attention to this hidden side of frog communication.

This is the first evidence of last-male advantage in granular pollen systems! 🌸 Our findings highlight the role of #sexualselection in plants and the intricate #co-evolution between #flowers and #pollinators.

The second male flower deposited more pollen on stigmas, even when controlling for time effects. This suggests smothering or displacement of the first male’s pollen, much like last-male sperm precedence in animals. #SexualSelection #MatingSystems

To teste these hypotheses, we used quantum dots, tagging flowers with color-coded markers. This allowed us to track pollen transfer to female flowers and develop the following predictions:

We tracked pollen on sunbirds visiting *Tritoniopsis antholyza* and tested two hypotheses:
1) Pollen preclusion: First male's pollen blocks later pollen.
2) Pollen smothering/displacement: Last male's pollen dominates.
