Abstract

It has been suggested that physical interactions between biological and environmental surfaces may constrain ecological niche spaces. However, the mechanistic understanding of niche formation is frequently limited by the lack of information on the function and variation of these interactions. Here, we hypothesised that two closely related species of orb-web spiders have evolved different adhesion performance of web attachment (i.e. piriform silk) facilitating the occupation of contrasting microhabitats: plants versus rocks. Contrary to our prediction, we found that piriform silk adhesion was equally affected by surface chemistry in both species, with maximal adhesion on surfaces with high surface polarity and an average adhesion loss of 70-75% on low polar surfaces. Spiders did not respond to adhesion losses by increasing the anchor size, despite the repeated failure to attach their web to low polar surfaces. In a natural setting, poor adhesion on low polar surfaces may be mitigated by behavioural means, like the preference to place anchors on corrugated surface features such as leaf edges, or the spinning of multiple anchorages and formation of a bundled anchor line. Thus, microhabitat choice for web-building spiders may be go...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.
