Data from: Transcriptomic analysis of skin pigmentation variation in the Virginia opossum (Didelphis virginiana).

Skin and coat pigmentation are two of the best-studied examples of traits under natural selection given their quantifiable fitness interactions with the environment (e.g. camouflage) and signaling with other organisms (e.g. warning coloration). Previous morphological studies have found that skin pigmentation variation in the Virginia opossum (Didelphis virginiana) is associated with variation in precipitation and temperatures across its distribution range following Gloger’s rule (lighter pigmentation in temperate environments). To investigate the molecular mechanism associated with...

Data from: Demographic costs and benefits of natural regeneration during tropical forest restoration

T. Trevor Caughlin, Marinés De La Peña-Domene & Cristina Martínez-Garza
For tropical forest restoration to result in long‐term biodiversity gains, native trees must establish self‐sustaining populations in degraded sites. While many have asked how seedling recruitment varies between restoration treatments, the long‐term fate of these recruits remains unknown. We address this research gap by tracking natural recruits of 27 species during the first 7 years of a tropical forest restoration experiment that included both planted and naturally regenerating plots. We used an individual‐based model to...

Data from: Sexual signals reveal males’ oxidative stress defenses: testing the hypothesis in an invertebrate

Norma Martínez-Lendech, Maria J. Golab, Marcela Osorio-Beristain & Jorge Contreras-Garduño
1.The hypothesis that sexual traits reveal the oxidative stress resistance of their bearers has been widely tested in vertebrates but remains unexplored in invertebrates. Here, Hetaerina americana was used to test whether oxidative stress defenses are advertised by male wing spot size and color (a male sexual trait). To this end we asked (1) whether oxidative stress reduced survival, (2) whether wing spot size revealed males’ antioxidant defenses, and (3) how wing spot size and...
