| 研究開始時の研究の概要 |
The goal of this research is to investigate the influence of latch morphology and orientation on the structural integrity of biological spring and latch mechanisms using the hyperdiverse trap-jaw ant genus Strumigenys as a model. Using a pre-existing MicroCT dataset of the jaw and latch morphologies of Strumigenys ants I will use finite element analysis to simulate loads on latched jaws at various angles to test for tradeoffs between jaw gape and the structural performance of the jaws and latching mechanism.

| 研究実績の概要 |
The objective of the research project was to investigate the influence of latch morphology and orientation on the structural mechanics of biological spring and latch mechanisms using the hyperdiverse trap-jaw ant genus Strumigenys as a model. This was to be done by using finite element analysis to simulate the loading of the spring and latch jaw mechanism of multiple species of Strumigenys which possess varying latch morphologies. Due to the shortened duration of the fellowship, only preliminary data was collected on the latch orientation during the loading phase of strikes for a single species of Strumigenys, which will be used to inform the boundary conditions of the eventual FEA models. Surprisingly these videos also showed evidence of head cuticle deformation during the loading phase of strikes in this species, which in other unrelated lineages of trap-jaw ants is known to assist in elastic energy storage for powering mandible strikes but was previously unknown to occur in Strumigenys. The collaboration between Drs. Gibson and Economo will continue past the conclusion of the fellowship and additional data and results will eventually be collected. Once completed, this research is expected to shed light on the fundamental relationships between morphology and stress mitigation in latch mediated spring powered biological systems.
