A single freshwater invasion gave rise to the world's dominant freshwater fish group

Delson Hays, Matthew A. Burnett, Aintzane Santaquiteria, Dahiana Arcila, Alexander Burnett, Olga Otero, Diogo Mayrinck, Ricardo Betancur‐R

The paper challenges the hypothesis of multiple freshwater invasions in otophysan fish by showing that a single invasion is more likely, based on phylogenetic and biogeographic analyses.

REPEATED MARINE-TO-FRESHWATER FISH TRANSITIONS REVEAL PALEOENVIRONMENTAL MODULATION OF ADAPTIVE RADIATION

Aline P. M. Medeiros, Melissa Rincón-Sandoval, Aaron M. Davis, Aintzane Santaquiteria, Christine E. Thacker, Joshua Egan, Jonathan Kim, Alfred Ko’ou, Dahiana Arcila, William B. Ludt, Lily C. Hughes, Devin D. Bloom, Ricardo Betancur‐R

The paper investigates marine-to-freshwater fish transitions in Sahul rivers, finding that diversification success depends on paleoenvironmental dynamics rather than just ecological opportunity.

Convergent evolution of extreme snout elongation in deep-sea fishes reveals constrained trajectories

Zach Heiple, Katherine E. Bemis, James C. Tyler, Aintzane Santaquiteria, Fernando Meléndez-Vazquez, Casey Lee, Kyoji Fujiwara, Masanori Nakae, Hsuan-Ching Hans Ho, John J. Pogonoski, William T. White, Mark W. Westneat, Ricardo Betancur‐R, Dahiana Arcila

The paper shows that extreme snout elongation in deep-sea fishes evolved independently but along constrained trajectories due to phenotypic integration and functional innovation.

Ecological axes of skull diversification in a massive 1 vertebrate radiation

Elizabeth Christina Santos, Rose Faucher, Aintzane Santaquiteria, JoJo West, Jonathan W. Armbruster, Carole Baldwin, Thaddaeus J. Buser, Kent Carpenter, Juan Martin Díaz De Astarloa, Melissa Rincón-Sandoval, Samantha M. Gartner, Shih-Pin Huang, Jin-Koo Kim, Hernán López‐Fernández, Nathan K. Lujan, , Dahiana Arcila

The paper analyzes skull diversification in eupercarian fishes, showing habitat and trophic ecology independently shape skull shape, with rapid evolution in certain clades and convergence in freshwater lineages.
