Biological materials are typically multifunctional but many have evolved to optimize a chief
mechanical function. These functions include impact or fracture resistance, armor and …

The tribal and generic classification of the diverse ant subfamily Ponerinae (Hymenoptera:
Formicidae) is revised to reflect recent molecular phylogenetic information and a reappraisal …

In ant colonies, collectivity enables division of labour and resources,–with great scalability.
Beyond their intricate social behaviours, individuals of the genus Odontomachus, also …

INTRODUCTION Mechanical power, whether for launched missiles or running humans, is
limited by the universal, physical trade-off between force and velocity. However, many …

Animals have evolved remarkable biomechanical and physiological systems that enable
their rich repertoire of motion. Animal Locomotion offers a fundamental understanding of …

Comprising a substantial part of living biomass on earth, ants are integral to the functioning
of terrestrial ecosystems. More than 12,000 species have been described to date, and it is …

Millions of years of evolution have allowed animals to develop unusual locomotion
capabilities. A striking example is the legless-jumping of click beetles and trap-jaw ants …

Rapid biological movements, such as the extraordinary strikes of mantis shrimp and
accelerations of jumping insects, have captivated generations of scientists and engineers …

Insects are the most ecologically important multicellular heterotrophs in terrestrial systems.
They play critical roles in ecological food webs, remain devastating agricultural and medical …

Publisher Summary This chapter outlines the evolution of geographic variation in birdsong.
Studies of vocal signals in birds offer potentially useful opportunities for empirical tests of the …
