Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae [PDF]

open access: yesAppl Plant Sci
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Revisiting Securidaca longipedunculata Seed Oil: Applying NMR and Mass Spectroscopy to Confirm the Presence of 2‐Acetyl‐1,3‐Diacyl–sn‐Glycerols and Conjugated Hydroxydienoic Fatty Acids

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.

Evaluation of Varnishes to Slow Down the Aging of Plasticized PVC

open access: yesJournal of Applied Polymer Science, EarlyView.
Varnish effectiveness in plasticized PVC strongly depends on both formulation and degradation state. A polyurethane varnish effectively limits color change and plasticizer loss in unaged PVC without phosphate plasticizers, whereas no protective effect is observed for phosphate‐containing PVC.

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐
