Honoring the Afro-Colombian musical culture with the naming of Epipedobates currulao sp. nov. (Anura: Dendrobatidae), a frog from the Pacific rainforests

M. Betancourth-Cundar, J. C. Rios-Orjuela, A. J. Crawford, D. C. Cannatella, R. D. Tarvin

This paper describes a new frog species, Epipedobates currulao, named after a Colombian musical genre, and provides morphological, acoustic, and genetic distinctions from related species.

Genome size evolution and phenotypic correlates in the poison frog family Dendrobatidae

T. E. Douglas, R. Marquez, V. R. D. Holmes, J. S. Johnston, R. D. Tarvin

This study estimates genome sizes for 32 poison frog species and finds gradual evolution with correlations to body size and reproductive traits, but no link to chemical defense evolution.

Selection on visual opsin genes in diurnal Neotropical frogs and loss of the SWS2 opsin in poison frogs

Y. C. Wan, M. J. Navarrete, L. A. O'Connell, L. H. Uricchio, A. B. Roland, M. E. Maan, S. R. Ron, M. Betancourth-Cundar, M. R. Pie, K. A. Howell, C. L. Richards-Zawacki, M. E. Cummings, D. C. Cannatella, J. C. Santos, R. D. Tarvin

The paper identifies positive selection on opsin genes in diurnal Neotropical frogs and reports the loss of SWS2 opsin in poison frogs, suggesting implications for their visual adaptation and chemical ecology.

Are Pacific Chorus Frogs (Pseudacris regilla) Resistant to Tetrodotoxin (TTX)? Characterizing Potential TTX Exposure and Resistance in an Ecological Associate of Pacific Newts (Taricha)

K. O. Montana, V. Ramirez-Castaneda, R. D. Tarvin

This study investigates whether Pacific Chorus Frogs (Pseudacris regilla) are resistant to tetrodotoxin (TTX) by analyzing sodium channel sequences and activity patterns relative to TTX-producing Taricha newts.

Trade-offs between cost of ingestion and rate of intake drive defensive toxin use

T. E. Douglas, S. G. Beskid, C. E. Gernand, B. E. Nirtaut, K. E. Tamsil, R. W. Fitch, R. D. Tarvin

The paper shows that Drosophila strains with higher toxin metabolism ingest more nicotine, leading to better survival against parasitism, suggesting toxin accumulation can evolve as a defensive strategy.
