Root climbers such as English ivy (Hedera helix) rely on specialized adventitious roots for attachment, enabling the plants to climb on a wide range of natural and artificial substrates. Despite their importance for the climbing habit, the biomechanical properties of these specialized adventitious roots compared with standard roots and their performance in the attachment to different host speci...

It has been much disputed whether seasonal variations in proteins or in sugars are better related to cold hardiness changes in certain over-wintering plants (for example, 1, 2, 3, 8, 12, 14). But proteins have been difficult to study, since they are not easily extracted from such plants as our native winter-hardy trees. This is because such proteins are often precipitated by vacuolar substances...

English ivy (Hedera helix) is well known for its ability to climb onto and strongly adhere to a variety of solid substrates. It has been discovered that the ivy aerial rootlet secretes an adhesive composed of polysaccharide and spherical nanoparticles. This study aims to characterize the mechanical properties of the nanocomposite adhesive using atomic force microscopy (AFM). The adhesive was fi...

Heat transfer through building envelopes is a crucial aspect of energy efficiency in construction. Masonry walls, being commonly used material, have significant impact on thermal performance. In recent years, green roofs and walls gained popularity as means improving efficiency, reducing urban heat islands, enhancing aesthetics. This study aims to investigate the effect ivy (Hedera helix) green...

Abstract Declines in floral resources, pollen and nectar, are considered one cause of pollinator decline. However, the supply demand resources can vary temporally. In Britain, autumn has been suggested as a period high resource availability due to flowering ivy ( Hedera helix ), common native plant, combined with fewer insects active during this season. Here, we directly quantified proportion n...
