Ecology and paleoecology of marine invertebrates
Marine invertebrates are subject to many biotic interactions. In modern ecosystems, these interactions can be analyzed in real-time and on a high temporal resolution. Major changes in morphology and behavior, however, can occur on a larger time-scale. The fossil record is a magnificent window to the past, allowing us to go back into ancient times and tracking changes in autecology, synecology, and morphological adaptations.
My research focuses on recent and fossil marine invertebrates with a particular focus on echinoids and spirulid cephalopods. My research interest is on their integration in the environment and evolution through geological times which is investigated in the light of biotic interaction. This includes specifically technical analysis of their bodies, also known as technical biology. This approach is not only used for a deeper understanding of biological structures, but also utilized in biomimetic research where functional principles in biological systems are transferred into engineering, architecture, and design.
Echinoids are important for the function and diversity of marine benthic communities in which they act as environmental engineers and represent a major food-source for various organisms. Even after death, the echinoid test is used by many invertebrates as housing or provide a secondary hard substrate for sessile organisms. To better understand their function and integration into the ecosystem, it is vitally important to understand morphological responses to their environment, identifying predatory networks, and describing taphonomic pathways.
Spirulid cephalopods are squid-like animals that predominantly inhabit the deep-sea. This taxon is of specific morphological interest as it represents the only known extant cephalopod possessing an coiled shell. This unique feature rises questions on their structure and function. In addition to the morphological, mechanica, and ecological implications, denuded shells possess an important value as mobilie floating substrates for sessile organisms.
Technical biology combines classical approaches with cutting-edge technologies including computational analytics, high-resolution 3d analyses and simulations. These techniques together with experimental setups and in-situ observations unite the strands of paleontology, biology and engineering sciences which provide an integrative approach allowing for a deep understanding of the role of marine invertebrates through time.
