Alexander Kupfer

Dr. Alexander Kupfer is a researcher and curator in the Department of Herpetology at the State Museum of Natural History Stuttgart. With a career spanning over two decades, he has held academic positions at the University of Potsdam (2011-2013), University of Siegen (2010-2011), and Friedrich-Schiller University Jena (2007-2010).

• Current role: Researcher & Curator, Herpetology (since 2014)
• Past roles: Interim Professor at University of Potsdam, Lecturer at University of Siegen, Postdoc at Natural History Museum London

Research Interests: Dr. Kupfer specializes in the evolutionary biology and reproductive ecology of amphibians and reptiles, focusing on:

• Evolution of parental care and skin-feeding in caecilian amphibians
• Sexual size dimorphism and its ecological implications
• Phylogenetic analysis of amphibian lineages
• Application of micro-CT, histochemistry, and stable isotope analysis
• Ecology of herpetofauna in Southwestern Germany

Recent Publications: His work spans 20 years, with a focus on caecilian amphibians (Ichthyophis, Geotrypetes, Siphonops), reproductive strategies, and ecological adaptations. Key trends include:

• Comparative studies of oviparous and viviparous species
• Analysis of trophic ecology using stable isotopes
• Evolution of cloacal anatomy and sperm storage
• Demographic studies linking growth patterns to conservation
• Phylogenetic investigations of Indian and Southeast Asian caecilians

Methodologies: Integrates scanning electron microscopy, micro-CT, histochemistry, and stable isotope analysis (δ15N) with field studies. His work on parental care in Boulengerula taitanus highlights evolutionary transitions toward viviparity.

Collaborations: Works with institutions in Germany, Thailand, Bolivia, and the UK. Affiliated with research teams studying tropical ecosystems, European newt populations, and caecilian phylogeny.
