Valorization of Yacon (Smallanthus sonchifolius) peel for peroxidase production and its immobilization on alginate beads for 2,4‐dichlorophenol bioconversion

The Canadian Journal of Chemical Engineering, EarlyView.
Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

Ecography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism
