Type catalogue of the Orthoptera collection in the Steinhardt Museum of Natural History, Tel Aviv University, Israel.

Types represent the most important specimens in natural history museums as they define a species and should usually be studied within the framework of revisions and new taxon descriptions, hence their documentation is of high importance. Orthoptera is a medium-size order of insects, but its members are important in many food chains as herbivores and as food for other animals. While the documentation of types in Orthoptera is overall very good thanks to the Orthoptera Species File site, there are still many gaps that need to be filled.

Locust behavior and city topology: A biodynamic approach for assessing urban flows.

A city's economic growth and the inhabitants' wellbeing are highly affected by its topology and connecting networks, which, in turn, influence movement and flows in the city. Flow relates to how a city is developed, organized, managed, and built. The analysis of flow in cities is challenging but essential.

The biomechanics of ultra-stretchable nerves.

When digging in the ground during egg laying the female locust extends her abdomen to 2-3 times of its original length. How the abdominal nervous system accommodates such extreme elongation remains unknown. We characterized and quantified the system's biomechanical response using controlled elongation and force measurements.

Self body-size perception in an insect.

Animals negotiating complex environments encounter a wide range of obstacles of different shapes and sizes. It is greatly beneficial for the animal to react to such obstacles in a precise, context-specific manner, in order to avoid harm or even simply to minimize energy expenditure. An essential key challenge is, therefore, an estimation of the animal's own physical characteristics, such as body size.

Omnivory in terrestrial arthropods: mixing plant and prey diets.

Many terrestrial communities include omnivorous arthropods that feed on both prey and plant resources. In this review we first discuss some unique morphological, physiological, and behavioral traits that enable omnivores to exploit such dissimilar foods, and we explore possible evolutionary pathways to omnivory. We then examine possible benefits and costs of omnivory, describe the relationships between omnivory and other high-order complex trophic interactions, and consider the stability level of communities with closed-loop omnivory.
