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)

The Evolution of Male Weapons Is Associated with the Type of Breeding Site in a Clade of Neotropical Frogs

Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation b...

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)

We're really happy to finally see this out in Integrative Zoology!

We investigated whether the type of breeding site influences the evolution of male weaponry, using Neotropical frogs from the subfamily Leptodactylinae as models. (1/3)

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.

When you see a calling frog, you probably think it’s a male, right?

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.

Ever wondered how flowers compete for space on a pollinator's body? Check out our new paper! 🌸

Led by @pammsantana.bsky.social, we reveal how plants with granular pollen can exhibit a last-male advantage. 🤓
