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

open access: yesAmerican 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),

Mutational load and adaptive variation are shaped by climate and species range dynamics in Vitis arizonica

open access: yesNew Phytologist, Volume 247, Issue 2, Page 998-1014, July 2025.
Summary Genetic load can reduce fitness and hinder adaptation. While its genetic underpinnings are well established, the influence of environmental variation on genetic load is less well characterized, as is the relationship between genetic load and putatively adaptive genetic variation.

Macroclimatic niche similarity and species relatedness shift their influence on species co‐occurrence in bryophyte forest communities across scales

open access: yesJournal of Ecology, Volume 113, Issue 6, Page 1546-1559, June 2025.
The relationship between epiphytic bryophyte species associations changes with scale. Macroclimatic niche similarity strongly influences co‐occurrence globally but less so at smaller scales. Most species interactions are positive or neutral across scales, though ~7% shift from positive at microhabitat to negative at regional scales, highlighting scale ...

¿Es relevante la ecología del comportamiento para entender y predecir la dinámica de las poblaciones?

open access: yesEcosistemas, 2014
La ecología de las poblaciones estudia cómo cambian el número y la composición (edades, sexos) de los individuos que forman una población. Muchos de los mecanismos que generan estos cambios están asociados con el comportamiento, por ejemplo por la forma ...
