Ecography, EarlyView.Patterns in functional and phylogenetic diversity reflect ecological and evolutionary relationships among taxa, and thus can offer key insights into the mechanisms underlying species distributions. However, disentangling the relative influence of proximate environmental drivers versus biogeographic evolutionary history can be a challenge.

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.

Microscopy Research and Technique, EarlyView.A paired comparison revealed that the sodium hypochlorite method offers several advantages over other techniques, better preserving anatomical structures, which facilitates detailed analysis. ABSTRACT This article describes precise and unpublished data on leaf anatomy of Melinis minutiflora P. Beauv.

New species and new records in Agarista (Ericaceae) from the Peruvian Andes
Nordic Journal of Botany, EarlyView.Agarista (Ericaceae) is currently represented in Peru by three species. Here, we update this number to five, adding new taxa based on the recognition of a taxonomic novelty and new records. The new species Agarista eugeniifolia differs from all congeneric species by an abaxially sulcate midvein.
