We provide, for the first time, an annotated checklist of the beetle fauna of Crete, Greece. We present an overview of the coleopterological history of Crete, along with background information of the physical attributes of the island. Data for the checklist were extracted from the collection of the Natural History Museum of Crete, GBIF, Fauna Europaea, the Catalogue of Palaearctic Coleoptera and various revisions. We report 2201 unique taxa (species or subspecies) belonging to 63 families. We also report 355 taxa as endemic to Crete or the surrounding islets, and 48 taxa as adventive to Crete. Fourteen new species records are reported, two for Buprestidae, two for Histeridae (including a new record for Greece), one for Oedemeridae (including a new record for Greece) and nine for Scarabaeidae. We compare the beetle fauna of Crete with the beetle fauna of Cyprus, Malta, and Sardinia within the Mediterranean Sea. Additionally, we provide comparisons with the California Channel Islands, the Canary Islands, the Galapagos Islands and the Socotra Archipelago.

Abstract Three-phase fluid-structure interaction (FSI) problems couple the motion of solid structures and two different fluids, often exhibiting complex dynamics and posing challenges for computational investigation. The main objective of this paper is to present a new computational framework for the modeling, simulation, and application of such problems. To that end, we propose an integrated numerical algorithm that utilizes the volume of fluid method for the two-fluid flow and the immersed boundary method for the fluid-solid interaction, with a special emphasis on three-phase FSI computation in micro-scale settings. To demonstrate our methodology, we conduct a pilot FSI study on cellulose microfibrils in plant cell walls by simulating the interaction between microfibrils and two fluids, pectin and water. We investigate the evolution of the flow fields, the speed and spatial organization of the microfibrils, and the impact of different initial settings on microfibril dynamics. We find that the microfibril-pectin-water interaction leads to transversely oriented microfibrils with respect to the elongation axis of the plant cell. The simulation results indicate that our methodology may provide a novel approach to investigate the complex behavior of microfibrils and gain insights into the intrinsic dynamical properties of such microstructures.
