Our goal is to understand which aspects of communication and interaction are affected by abiotic factors (with a focus on temperature, pH, and oxygen) and anthropogenic substances, and what strategies organisms employ to compensate for these effects. In doing so, we integrate aspects across different timescales: chemical effects on the picosecond scale, molecular biological and ecological responses ranging from milliseconds to daily rhythms and years, up to long-term climate change effects. Our specific focus is on the direct environmental effects on natural and anthropogenic substances and the associated processes.</p> Content content-536112 Thu, 05 Mar 2026 12:36:58 +0100 https://www.uni-bremen.de/en/roggatz#c536112 <p>Dr. Christina Roggatz<br /> BIOM 3790<br /> James-Watt-Str. 1<br /> 28359 Bremen</p> <p>+49 (0)421 218 56658</p> <p><a class="mail" href="mailto:croggatz@uni-bremen.de" title="Opens a window for sending an e-mail">croggatz@uni-bremen.de</a></p> Content content-719534 Tue, 07 Apr 2026 09:47:32 +0200 https://www.uni-bremen.de/en/roggatz#c719534 Content
