AbstractMain conclusionA mixture of resins based on aliphatic esters and carboxylic acids occurs in distantly related generaPeperomiaandRoridula, serving different functions as adhesion in seed dispersal and prey capture. According to mechanical characteristics, adhesive secretions on both leaves of the carnivorous flypaper Roridula gorgonias and epizoochorous fruits of Peperomia polystachya were expected to be similar. The chemical analysis of these adhesives turned out to be challenging… 
Chemical and morpho-functional aspects of the interaction between a Neotropical resin bug and a sticky plant
The morphology of the plant’s glandular trichomes with the aid of light and scanning electron microscopy, as well as the chemical components of the exudate by histochemical and gas chromatography-mass spectrometry analysis, are described to identify possible morpho-functional adaptations evolved by H. stali for collecting the sticky secretions.
Physical Characterization of Latex from Artocarpus heterophyllus Lam. (Jackfruit) and Four Related Artocarpus spp.
This study focused on the physical properties of latex extracted from five species of Artocarpus J.R.Forster & G.Forster, namely: A. altilis (Parkinson) Fosberg, A. blancoi Merr, A. camansi Blanco,
Robust, universal, and persistent bud secretion adhesion in horse-chestnut trees
A multi-component material (aliphatic hydrocarbon resin), including alkanes, fatty acids, amides, and tackifying terpenoids embedded in a fluid matrix comprising nonpolar and polar portions serving the universal and robust adhesive properties.
Foliar behaviour of biogenic semi-volatiles: potential applications in sustainable pest management
Recent literature of the plant surface–environment interaction of biogenic sVOCs is reviewed and potential crop protection strategies such as intercropping and companion planting using sV OC-emitting species are evaluated.
Evolution of Epiphytism and Fruit Traits Act Unevenly on the Diversification of the Species-Rich Genus Peperomia (Piperaceae)
The success of Peperomia is likely the result of enhanced vertical and horizontal dispersal ability and life form flexibility but not the evolution of epiphytism itself, and evolutionary flexibility of life forms is uncovered to coincide with the diversification shift.
Thermal and Rheological Properties of the Mucilage from the Fruit of Cordia lutea
The findings reported in the present work suggest that C. lutea mucilage can be used as a rheology modifier for commercial foods and biomedical materials.
Seeing the wood despite the trees: Exploring human disturbance impact on plant diversity, community structure, and standing biomass in fragmented high Andean forests
It is found that the increase of human‐related disturbance resulted in less phylogenetic diversity and in the phylogenetic clustering of the woody vegetation and in lower aboveground biomass (AGB) values, and that AGB was efficiently predicted by the proportion of late successional species.
Bio-based and bio-inspired adhesives from animals and plants for biomedical applications
With the “many-headed” slime mold Physarum polycelphalum having been voted the unicellular organism of the year 2021 by the German Society of Protozoology, we are reminded that a large part of


Plant resins—their formation, secretion and possible functions
This chapter focuses on the external resins that are secreted onto leaf surfaces, but it also provides information on resins, which remain within the plant, and other related plant products.
Hierarchical organisation of the trap in the protocarnivorous plant Roridula gorgonias (Roridulaceae)
The hypothesis that the shortest trichomes are adapted to strong, long-term adherence to prey insects, and that the longest trICHomes are responsible for initial trapping and entanglement function, is supported.
Adhesive Strength of the Insect-Trapping Glue of a Plant (Befaria racemosa)
It is suggested that nitrogenous decay products leaching into the soil from the dead insects trapped by the plant may add organic nutrient to the acid sandy soil in which Befaria characteristically lives.
Distribution and function of resins and glandular hairs in Western Australian plants
Some properties of the leaf resins of Beyeria viscosa and Eremophila fraseri are discussed in detail and may have a function in reducing water loss by increasing resistance to cuticular transpiration and by reducing leaf temperature by increasing radiation reflectance from the leaf.
A universal glue: underwater adhesion of the secretion of the carnivorous flypaper plant Roridula gorgonias
The robustness of the secretion to a wet environment presumably enables the plant to maintain its trapping function also under humid conditions and during rainy weather.
An insect trap as habitat: cohesion-failure mechanism prevents adhesion of Pameridea roridulae bugs to the sticky surface of the plant Roridula gorgonias
Results indicate that, when trapping prey, the plant adhesive might form proper contact with solid islands of the insect cuticle that are free of epicuticular grease.
Desiccation resistance of adhesive secretion in the protocarnivorous plant Roridula gorgonias as an adaptation to periodically dry environment
To analyse the change of mass in the resinous secretion of Roridula gorgonias, long-term measurements using a computerised ultra microbalance found no significant desiccation of secretory drops within 10 h of continuous weighing.
Mineral nutrient uptake from prey and glandular phosphatase activity as a dual test of carnivory in semi-desert plants with glandular leaves suspected of carnivory.
Roridula and Drosophyllum appeared to be fully carnivorous; by contrast, all other species examined are non-carnivorous as they did not meet the above criteria.
Wood anatomy of Roridula is congruent with relationships alleged by various authors to the genus Byblis, and very similar secondary xylem features can be found in such "rosoid" families as Saxifragaceae, Hamamelidaceae, Bruniaceae, and Grubbiaceae.
Jasmonates trigger prey-induced formation of ‘outer stomach’ in carnivorous sundew plants
It is reported that prey capture induces both leaf bending and the accumulation of defence-related jasmonate phytohormones, suggesting that in carnivorous sundew plants the jasMonate cascade might have been adapted to facilitate carnivory rather than to defend against herbivores.
