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.

Three first records of stick insects attacking plants (Inseect: Phasmida) in Tibet
Brazilian Journal of Biology, 2021 Except for a few stick insects that are economically valuable, most species be considered to be forest pests, so it is extremely important to obtain plant host-use information of more stick insects.

New Anthracenone and Xanthenones From Tricholaena teneriffae With Antioxidant Activity: In Vitro and In Silico Studies. [PDF]
Chem BiodiversThree novel phenolic compounds and one known benzoxanthenone are isolated from Tricholaena teneriffae. Compounds (1–3) demonstrate potent antioxidant activity, comparable to that of vitamin C, while compound (4) exhibits negligible activity. Docking studies are employed to validate the binding of the compounds to lipoxygenase‐3, providing evidence of ...

Oligocene niche shift, Miocene diversification – cold tolerance and accelerated speciation rates in the St. John’s Worts (Hypericum, Hypericaceae) [PDF]
, 2015 Background: Our aim is to understand the evolution of species-rich plant groups that shifted from tropical into cold/temperate biomes. It is well known that climate affects evolutionary processes, such as how fast species diversify, species range shifts,

Studies on the Feculae of Selected Michigan Acrididae (Orthoptera) [PDF]
, 2017 Feculae have been used for some years in the study of insect food-habits and biology. Among the past authors who have used them are Frost (1928), Hodson and Brooks (1956), and Morris (1942), who discussed the use of feculae and frass in the ...
