Journal ArticleDOI
The triterpene glycosides of Holothuria forskali: usefulness and efficiency as a chemical defense mechanism against predatory fish.
Séverine Van Dyck,Guillaume Caulier,Maïté Todesco,Pascal Gerbaux,Isabelle Fournier,Maxence Wisztorski,Patrick Flammang +6 more
TL;DR: The deterrent effect of saponins seems to act as an aposematic signal, warning potential predators of the unpalatability of the holothuroid tissues.
Review of saponin diversity in sea cucumbers belonging to the family Holothuriidae
TL;DR: All of the data combined indicate a complex chemical defence mechanism with different sets of saponins originating from different body compartments and presenting different properties in relation to their ecological role(s).
Journal ArticleDOI
Is non-host pollen suitable for generalist bumblebees?
Maryse Vanderplanck,Sylvain Decleves,Nathalie Roger,Corentin Decroo,Guillaume Caulier,Gaétan Glauser,Pascal Gerbaux,Georges Lognay,Aurore Richel,Nathalie Escaravage,Denis Michez +10 more
TL;DR: The results of this study strongly suggest that pollen traits may act as drivers of plant selection by bees and partly explain why Asteraceae pollen is rare in bee generalist diet.
Journal ArticleDOI
When a repellent becomes an attractant: harmful saponins are kairomones attracting the symbiotic Harlequin crab
TL;DR: This study identifies for the first time the nature of the molecules secreted by sea cucumbers and attracting the symbionts: saponins are the kairomones recognized by the crabs and insuring the symbiosis.
Journal ArticleDOI
Molecular diversity and body distribution of saponins in the sea star Asterias rubens by mass spectrometry.
Marie Demeyer,Julien De Winter,Guillaume Caulier,Igor Eeckhaut,Patrick Flammang,Pascal Gerbaux +5 more
TL;DR: The observed high variability of saponin contents unambiguously confirms that saponins probably fulfill several biological functions in A. rubens at a molecular level.
