Stacked scattering: The key to bright flowers lies in the mesophyll. [PDF]
Am J BotAbstract Premise The coloration of flowers is caused by wavelength‐selective absorption by pigments and scattering of light by floral structures. Although the molecular, physiological, and chemical properties of floral pigments have been studied in considerable detail, how floral structures contribute to the visual signal remains largely unknown.

The developmental basis of floral nectary diversity and evolution. [PDF]
New PhytolSummary Nectar is a central bridge between angiosperms and animal mutualists. It is produced by specialized structures termed nectaries, which can be found on different plant organs. Consumption of floral nectar by pollinators and the subsequent transfer of pollen contribute to the reproductive success of both angiosperms and their pollinators.

Integrating comparative morphology and development into evolutionary research
TAXON, Volume 72, Issue 4, Page 724-732, August 2023., 2023 Abstract Comparative morphology was for many years the main source of information for systematic studies. As a result of the molecular revolution in evolutionary botanical research in the early 1990s, we can now rely on a system of classification based primarily or exclusively on DNA.

Biocultural Calendars Across Four Ethnolinguistic Communities in Southwestern South America
GeoHealth, Volume 7, Issue 4, April 2023., 2023 Abstract Since the mid‐20th century, the so‐called Great Acceleration (sensu Steffen et al., 2007, https://doi.org/10.1579/0044-7447(2007)36[614:TAAHNO]2.0.CO;2) has amplified processes of ecosystem degradation, extinction of biological species, displacement of local peoples, losses of languages, and cultural diversity.
