Reduced sexual size dimorphism in a pipefish population where males do not prefer larger females

Nuno Monteiro, Mário Cunha, Nídia Macedo, Jonathan Wilson, Gunilla Rosenqvist & Anders Berglund
Within a species’ distribution, populations are often exposed to diverse environments and may thus experience different sources of both natural and sexual selection. These differences are likely to impact the balance between costs and benefits to individuals seeking reproduction, thus entailing evolutionary repercussions. Here, we look into an unusual population (Baltic Sea) of the broadnosed pipefish, Syngnathus typhle, where males do not seem to select females based on size and hypothesise that this pattern may...

Data from: Variable outcomes of hybridization between declining Alosa alosa and Alosa fallax

Olivier Lepais, Laura Taillebois, Stephen Sabatino, Aurélie Manicki, Françoise Daverat & David José Nachon
Hybridization dynamics between co-occurring species in environments where human-mediated changes take place is important to quantify for furthering our understanding of human impacts on species evolution and for informing management. The allis shad Alosa alosa (Linnaeus, 1758) and twaite shad Alosa fallax (Lacépède, 1803), two clupeids sister species, have been severely impacted by human activities across Europe. The shrinkage of A. alosa distribution range along with the decline of the remaining populations’ abundance threaten its...
