The Light Bite: Red‐Nosed Cuxiu (Chiropotes albinasus, Primates) Exploit Differential Penetrability of Hard Fruit Husks When Selecting Dental Puncture Sites

Biotropica, Volume 57, Issue 6, November 2025.
Red‐nosed cuxiu are specialists in unripe seeds of hard‐husked fruits, which they access with massive jaw muscles and enlarged canines. But this costs energy and risks tooth breakage. The monkeys reduce both by biting at the softest spots on the fruit surface.

Enzymatic Interesterification: An Innovative Strategy for Lower‐Calorie Lipid Production From Refined Peanut Oil

Journal of Food Science, Volume 90, Issue 10, October 2025.
ABSTRACT This study aimed to evaluate the fatty acid (FA) composition of Brazilian refined peanut oil (RPO) and the effect of enzymatic interesterification on its regiodistribution, aiming the production of lipids with lower digestibility and, consequently, lower caloric value, in line with current consumption trends focused on health.

Insights on the Potential of Natural Regeneration to Restore Cerrado Open Ecosystems

Austral Ecology, Volume 50, Issue 9, September 2025.
The colonisation potential of native Cerrado species in degraded areas will depend on the remaining underground structures and not on seed rain from nearby conserved remnants. Effective restoration of the Cerrado will not be possible without active restoration, if the bud‐bank are not present in the system.
