Dermato-cosmeceutical properties of Pseudobombax ellipticum (Kunth) Dugand: Chemical profiling, in vitro and in silico studies. [PDF]
Plant extracts and their individual components have been used to manage skin aging for several decades. Recently, the discovery of new natural bioactive agents, that not only enhance the skin health but also offer protection against various deleterious factors, such as free radicals, ultraviolet radiation, and microbial infections, has been a potential

Effects of genetic vs. environmental quality on condition-dependent morphological and life history traits in a neriid fly. [PDF]
In many animals (like the neriid flies below), the expression of male condition‐dependent traits is influenced by both genetic and environmental quality. We show that the environmental component has much more consistent effects on trait expression. Our findings raise questions about the potential for condition‐dependent traits to signal genetic quality.

Sexual Selection Associated With an Aggressive Male Phenotype Reduces Population Size and Hinders Population Recovery After Heat Stress. [PDF]
Using experiments on soil mites, we show that sexual selection associated with an armed and aggressive male phenotype can reduce population size and stability, which lowers their resilience against acute heat stress. These effects linked with armed and aggressive phenotypes underline the importance of sexual selection in mediating population dynamics ...

Evolution of crop phenotypic spaces through domestication. [PDF]
Summary We used domestication as an in vivo replicated experiment to investigate how divergent selection has shaped the evolution of multivariate phenotypic spaces. We measured 11–57 qualitative and quantitative traits in 13 species, either unique or shared between species, and established a framework for cross‐species comparisons. Our results revealed

A century of theories of balancing selection. [PDF]
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Environmental heterogeneity influences liana community differentiation across a Neotropical rainforest landscape. [PDF]
By analyzing liana community variation among land units (LUs) that differ in geomorphology and soil properties along a 640‐ha tropical rainforest landscape in a neotropical reserve, we found strong evidence supporting our hypothesis that environmental heterogeneity, as represented by discrete LUs, promotes differentiation in liana composition across ...

Summary Rapid environmental change is forcing populations into environments where plasticity will no longer maintain fitness. When populations are exposed to novel environments, evolutionary theory predicts that genetic variation in fitness will increase and should be associated with genetic differences in plasticity. If true, then genetic variation in
