Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3230-3246, June 2026.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Seed dormancy explains plant response to mass mortality events

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 907-921, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mass mortality events (MMEs) are large‐scale, rapid die‐offs resulting in extreme inputs of carrion biomass. Recent work demonstrates the effects of increasing carrion biomass on plant communities modulated by vertebrate scavengers and herbivores.
