About
Dr. Steven Ramm is an evolutionary biologist at Bielefeld University, serving as an Associate Member of the SFB/Transregio 212 "A Novel Synthesis of Individualization across Behavior, Ecology and Evolution: Niche Choice, Niche Conformance, Niche Construction" (NC³) and affiliated with the Joint Institute for Individualization in a Changing Environment (JICE). His research focuses on the evolutionary mechanisms underlying reproductive strategies, with particular emphasis on sexual selection, sperm competition, and sex allocation.
Dr. Ramm's research interests span several interconnected areas within evolutionary biology:
- Sexual selection and its role in shaping reproductive traits
- Sperm competition dynamics and evolutionary consequences
- Sex allocation strategies in hermaphroditic and dioecious organisms
- Effects of environmental factors (particularly temperature) on reproductive success
- Molecular mechanisms underlying seminal fluid function and sperm competition
- Experimental evolution approaches to understanding reproductive adaptation
His recent publications demonstrate a strong focus on understanding how temperature changes affect fertility and reproductive success across animal taxa, with increasing use of meta-analytical approaches. There's also a clear emphasis on hermaphroditic systems, particularly flatworms like Macrostomum lignano, to investigate fundamental questions about sex allocation, selfing strategies, and the evolution of reproductive traits under different selective pressures. His work bridges molecular, physiological, and evolutionary perspectives to address key questions in reproductive biology.
Dr. Ramm has been actively involved in collaborative research through the SFB/Transregio 212 consortium, which examines individualization processes across multiple biological scales. His work contributes to understanding how reproductive strategies evolve in response to environmental challenges and social contexts, with implications for predicting how species might respond to ongoing climate change.
