From micro to nano contacts in biological attachment devices
An extensive microscopic study has shown a strong inverse scaling effect in these attachment devices, whereas μm dimensions of the terminal elements of the setae are sufficient for flies and beetles, geckos must resort to sub-μm devices to ensure adhesion.
Ultrastructure of attachment specializations of hexapods (Arthropoda): evolutionary patterns inferred from a revised ordinal phylogeny
The analysis demonstrates, that similar structures (arolium, euplantulae, hairy tarsomeres) have evolved independently in several lineages, and some of them support monophyletic groups (e.g. Embioptera + Dermaptera; Dictyoptera + Phasmatodea; Hymenoptera+ Mecopterida; Neuropterida + Strepsiptera + Coleoptera).
Food Supply and Seawater pCO2 Impact Calcification and Internal Shell Dissolution in the Blue Mussel Mytilus edulis
These findings illustrate for the first time that integrity of inner shell surfaces is tightly coupled to the animals' energy budget under conditions of CO2 stress and suggest that under food limited conditions, energy is allocated to more vital processes instead of shell conservation.

The principles of cuticular attachment in Arthropoda and its applications in frictional systems and dragonfly and damselfly head-arresting system are explained.
Evidence for capillarity contributions to gecko adhesion from single spatula nanomechanical measurements.
Measurements of the adhesion force exerted by a single gecko spatula for various atmospheric conditions and surface chemistries show that humidity contributes significantly to gecko adhesion on a nanoscopic level, crucial for the development of artificial biomimetic attachment systems.
A Revised Interpretation of the Evolution of Attachment Structures in Hexapoda with Special Emphasis on Mantophasmatodea
Characters of hexapod attachment structures were analysed cladistically together with 110 additional morphological characters of immatures and adults. The results suggest the monophyly of Hexapoda,
Roughness-dependent friction force of the tarsal claw system in the beetle Pachnoda marginata (Coleoptera, Scarabaeidae).
This paper studies slide-resisting forces generated by claws in the free-walking beetle Pachnoda marginata with emphasis on the relationship between the dimension of the claw tip and the substrate texture, and proposes a model explaining the saturation of friction force with increased texture roughness.
Seed Dispersal by Ants in a Deciduous Forest Ecosystem
The myrmecochorous syndrome is a major explanatory factor in the decline in the ability of ants to remove diaspores from ant nests and the dispersal systems used for this removal are poorly understood.
The effect of surface roughness on the adhesion of elastic plates with application to biological systems
We study the influence of surface roughness on the adhesion of elastic plates. Most real surfaces have roughness on many different length scales, and this fact is taken into account in our analysis.
