Salivary/Serum Progesterone Ratio Differs Between Menstrual Cycle Phases but Not Between Populations: Implications for Health, Reproductive, and Behavioral Research

American Journal of Human Biology, Volume 37, Issue 7, July 2025.
Scatterplot of paired measurements of PFree‐SAL (y‐axis, log scale) versus PTotal‐VEN (x‐axis, log scale) for each of our 36 Bolivian study participants. Dotted diagonals represent lines of constant uptake fraction (UF = PFree‐SAL/PTotal‐VEN) from 0.2% to 100%. The solid red line represents the linear regression model for luteal phase pairs (red dots),

Drastic mycorrhizal community shifts in Sceptridium ferns during the generation transition from fully mycoheterotrophic gametophytes to photosynthetic sporophytes

New Phytologist, Volume 245, Issue 4, Page 1705-1717, February 2025.
Summary Many plant species experience a prolonged subterranean phase during which they rely entirely on mycorrhizal fungi for carbon. While this mycoheterotrophic strategy spans liverworts, lycophytes, and ferns, most empirical research has centered on angiosperms.
