History of divergence and gene flow shaping geographic variation in Andean warblers (Myioborus).

Studying how genetic variation is structured across space, and how it relates to divergence in phenotypic traits relevant to reproductive isolation, is important for our understanding of the speciation process. We used ddRAD-seq data to examine genetic variation across the distri...

Synergistic Biomass-Eggshell Engineering of Calcium Catalysts for Efficient Biodiesel Production

The valorization of agricultural and food-processing waste offers a promising pathway to develop cost-effective heterogeneous catalysts for biodiesel production. Herein, calcium-based catalysts were prepared by pyrolyzing mixtures of rice husk (RH) and eggshell (ES) at different...

Stingless bee honeys: the missing piece in harmonized authenticity and quality standards

Stingless bee honeys are among the most chemically diverse and bioactive honeys yet remain largely excluded from international authenticity standards centered on Apis mellifera . This exclusion may limit equitable market participation and the sustainable valorization of indigenou...
