Research interests (Description)
I am an evolutionary paleobiologist documenting and interpreting the relative contributions of abiotic (e.g., climate) and biotic factors (e.g., parasitism) in driving large-scale ecological and evolutionary patterns in the history of life.
Current research focuses on macroecology, biotic interactions, and biomineralization. For example: How does body size distribution and growth respond to climate warming and related environmental stressors? How does parasitism relate to host biodiversity and disease? How does seawater chemistry affect biomineralization of aquatic ectotherms?
For this purpose, I strive to work across disciplines and find means to test hypotheses with different lines of evidence, ranging from evolutionary ecology, over quantitative and molecular (paleo)biology, to developmental paleobiology, (paleo)parasitology and earth sciences.
I also work in other research areas, principally biogeography, biostatistics and geometric morphometrics, environmental analysis, experimental taphonomy and phylogenetic analysis. I remain active and maintain interest in methods (sample preparation and quantitative analyses) used in all these fields. I would therefore be happy to advise students in these and other areas.
Latest student research includes: diversity and body size dynamics of marine invertebrates, Holocene trends in parasite-host prevalence captured in coprolites and skeletal pathologies, 3D-reconstruction and morphometry as well as experimental taphonomy of invertebrates and vertebrates.

abstract = {Today parasites comprise a huge proportion of living biodiversity and play a major role in shaping community structure. Given their ecological significance, parasite extinctions could result in massive cascading effects across ecosystems. It is therefore crucial that we have a way of estimating their extinction risk. Attempts to do this have often relied on information about host extinction risk, without explicitly incorporating information about the parasites. However, assuming an identical risk may be misleading. Here, we apply a novel metric to estimate the cophylogenetic extinction rate, Ec, of parasites with their hosts. This metric incorporates information about the evolutionary history of parasites and hosts that can be estimated using event-based cophylogenetic methods. To explore this metric, we investigated the use of different cophylogenetic methods to inform the Ec rate, based on the analysis of polystome parasites and their anuran hosts. We show using both parsimony- and model-based approaches that different methods can have a large effect on extinction risk estimation.

Today parasites comprise a huge proportion of living biodiversity and play a major role in shaping community structure. Given their ecological significance, parasite extinctions could result in massive cascading effects across ecosystems. It is therefore crucial that we have a way of estimating their extinction risk. Attempts to do this have often relied on information about host extinction risk, without explicitly incorporating information about the parasites. However, assuming an identical risk may be misleading. Here, we apply a novel metric to estimate the cophylogenetic extinction rate, Ec, of parasites with their hosts. This metric incorporates information about the evolutionary history of parasites and hosts that can be estimated using event-based cophylogenetic methods. To explore this metric, we investigated the use of different cophylogenetic methods to inform the Ec rate, based on the analysis of polystome parasites and their anuran hosts. We show using both parsimony- and model-based approaches that different methods can have a large effect on extinction risk estimation. Further, we demonstrate that model-based approaches offer greater potential to provide insights into cophylogenetic history and extinction risk.

This bias requires addressing because parasites are a major component of biodiversity. We address this imbalance by focusing on transitions of parasitic animals between marine and freshwater environments. We highlight parasite traits and processes that may influence transition likelihood (e.g., transmission mode, life cycle, host use), and consider mechanisms and directions of transitions. Evidence for transitions in deep time and at present are described, and transitions in our changing world are considered. We propose that environmental transitions may be facilitated for endoparasites because hosts reduce exposure to physiologically challenging environments and argue that adoption of an endoparasitic lifestyle entails an equivalent transitioning process as organisms switch from living in one environment (e.g., freshwater, seawater, or air) to living symbiotically within hosts. Environmental transitions of parasites have repeatedly resulted in novel forms and diversification, contributing to the tree of life. Recognizing the potential processes underlying present-day and future environmental transitions is crucial in view of our changing world and the current biodiversity crisis.},
